Published: September 2023

Abstract

Students with learning disabilities have increased continuously from last few decades’ due to this threat of emerging academic, social, and psychological issues increased automatically. Students who have a fixed mindset that their qualities are fixed, whereas those who have a growth mindset that their qualities are flexible. The current applied research investigated Pakistan's Superior University the efficiency of a Growth Mindset intervention based on (Dweck, Chiu, & Hong, 1995) theory. Through project-based learning, this study indicates to determine how an intelligence scale and learning disabilities affect students' growth mindsets. Results of Before Intervention Test (BIT) were ineffective, so an After Intervention Test (AIT) was implemented through a project-based learning activity, and significant results were discovered. The validity and reliability tests were employed in this work to support the analysis of multiple linear regression. The findings of this study indicate that student growth attitude is highly influenced by both learning disability (X2) and IQ scale (X1), as well as by all other variables taken together. If researchers, administrators, teachers, and other people have a better knowledge of the mindsets of students with learning disabilities, they will be better able to develop effective solutions.

Published: September 2023

Abstract

The pressure surge at the moment of blasting seriously threatens the safety of pipeline structures and other buildings. This article established two numerical simulation models of the hydraulic transition process and water–air two-phase flow based on the one-dimensional transient flow theory and considering the actual flow characteristics of water and air. The hydraulic characteristics and blasting parameters of the blasting system were studied under two different conditions of the tunnel with and without the pressure flow. The observed parameters of an actual blasting engineering prototype verified the accuracy of the mathematical model. The maximum pressure of pressure blasting was 2.55 times as high as hydrostatic pressure. The maximum pressure of non-pressure blasting was 1.77 times as high as hydrostatic pressure. Pressure blasting impact was 2.17 times greater than nonpressure blasting. Discrepancies between actual and simulated data for gushing and overflow heights ranged from 9 to 14%. The model can provide a reference for blasting engineering on the simulation calculation of hydraulic characteristics such as impact pressure, overflow time, and overflow of the underwater rock plug blasting system.
Upstream vortices of a sluice gate: An experimental and numerical study
Authors: Norouzi Reza , Ebadzadeh Parisa , Sume Veli , Daneshfaraz Rasoul 
Published: September 2023

Abstract

This paper aims to explore the effects of a sill under a standard sluice gate on the development of the intake vortices. In total, 200 experiments were carried out. Sills with different shapes and widths were considered both numerically and experimentally. Results indicated that using a sill changes the flow depth and upstream pressure. Using a silled gate causes a decrease in the amount of air entering the fluid. By increasing the sill width, the vortex intensity reduces and this reduction is further amplified by increasing the approach discharge. The experimental findings are also compared to the results from the numerical model Flow-3D with interesting agreements.

Abstract

Achieving safely managed sanitation (SMS) in rural areas has spurred innovation in toilet designs that provide on-site treatment of fecal sludge (FS), including the development of International Development Enterprise (iDE)’s alternating dual-pit latrine upgrade (ADP). ADPs treat FS by inactivating pathogens using storage treatment with lime; however, ADPs’ reduction in pathogenicity (and thus their associated public health benefit) has not yet been described in real-world pits at scale. We thus enumerate the fecal indicator bacteria Escherichia coli (E. coli) and fecal coliforms in 147 pits after two years of storage treatment with lime and compare detected concentrations to relevant standards. E. coli and fecal coliform concentrations indicated a risk to human health in 31% and 42% of sampled pits, respectively. Regression models described relationships between fecal indicator bacteria concentrations and measured factors (e.g., sludge pH, temperature) but did not reveal any meaningful associations. High rates of pit ineligibility also indicate that many ADPs are not operated as recommended. Results indicate a one-in-three chance that a household emptying their own pit would be exposed to health hazards and call into question the effectiveness of the standard two-year storage treatment in real-world applications. To improve rural SMS, various evidence-based recommendations are made.
Design Guidelines of Mobile Apps for Older Adults: Systematic Review and Thematic Analysis

Published: September 2023

Background
Mobile apps are fundamental tools in today’s society for practical and social endeavors. However, these technologies are often not usable for older users. Given the increased use of mobile apps by this group of users and the impact that certain services may have on their quality of life, such as mobile health, personal finance, or online administrative procedures, a clear set of guidelines for mobile app designers is needed. Existing recommendations for older adults focus on investigations with certain groups of older adults or have not been extracted from experimental results.

Objective
In this research work, we systematically reviewed the scientific literature that provided recommendations for the design of mobile apps based on usability testing with older adults and organized such recommendations into a meaningful set of design guidelines.

Methods
We conducted a systematic literature review of journal and conference articles from 2010 to 2021. We included articles that carried out usability tests with populations aged >60 years and presented transferable guidelines on mobile software design, resulting in a final set of 40 articles. We then carried out a thematic analysis with 3 rounds of analysis to provide meaning to an otherwise diverse set of recommendations. At this stage, we discarded recommendations that were made by just 1 article, were based on a specific mobile app and were therefore nontransferrable, were based on other authors’ literature (as opposed to recommendations based on the results of usability tests), or were not sufficiently argued. With the remaining recommendations, we identified commonalities, wrote a faithful statement for each guideline, used a common language for the entire set, and organized the guidelines into categories, thereby giving shape to an otherwise diverse set of recommendations.

Results
Among the 27 resulting guidelines, the rules Simplify and Increase the size and distance between interactive controls were transversal and of the greatest significance. The rest of the guidelines were divided into 5 categories (Help & Training, Navigation, Visual Design, Cognitive Load, and Interaction) and consequent subcategories in Visual Design (Layout, Icons, and Appearance) and Interaction (Input and Output). The recommendations were structured, explained in detail, and illustrated with applied examples extracted from the selected studies, where appropriate. We discussed the design implications of applying these guidelines, contextualized with relevant studies. We also discussed the limitations of the approach followed, stressing the need for further experimentation to gain a better understanding of how older adults use mobile apps and how to better design such apps with these users in mind.

Conclusions
The compiled guidelines support the design of mobile apps that cater to the needs of older adults because they are based on the results of actual usability tests with users aged >60 years.

Water pollution from manufacturing waste and air pollution from forest and land fires are major environmental issues in the Siak district. This research aimed at gathering empirical data by implementing a real-action project based on SSCS learning to enhance sustainability awareness of Junior High School. This quasi-experiment was carried out in two groups of students in 7th grade of SMPN 1 Koto Gasib, Siak, Riau Province. The experimental class used the SSCS learning model with the ESD approach and the control class applied the scientific learning model. Indicators of sustainability awareness comprise: 1) Sustainability Practice Awareness; 2) Behavioral and Attitude Awareness; and 3) Emotional Awareness. Real-action project that is implemented by the teacher in this research is conducted to promote sustainability awareness in the form of a water purification model, planting pollution-absorbing plants, and creating Eco-brick flower pots. Data analysis uses inferential statistics, namely the T-test using SPSS-26 software. The analysis results of sustainability awareness indicate that students in the experimental class get a higher average of 76%, with the high category. Meanwhile, students in the control class get an average of 65% in the medium category. The T-test analysis of sustainability awareness gets a significance value of 0,002. 0,05, which indicates that there is a significant difference between experimental and control classes. The implementation of SSCS learning model using ESD approach can enhance the students’ sustainability awareness through environmental problem-solving activities, as well as building knowledge, behavior, and attitudes of love for the environment.

Authors: Жданова С.М. , Малин М.И. 
Published: September 2023

В марте 2019 г. изучены таксономический состав, вертикальное и горизонтальное распределение зоопланктона в оз. Плещеево. Установлено, что его обилие невелико (численность 11.5–13.8 тыс. экз./м3, биомасса < 0.1 г/м3), значительно ниже, чем регистрировали в этот сезон в 1980–90-х гг. Среди ракообразных, как и прежде, преобладал холодолюбивый Cyclops kolensis. Отмечено возрастание доли представителей р. Synchaeta, которые составляли до 12–27% общей численности коловраток. В то же время наблюдалось снижение обилия Eudiaptomus graciloides, ранее многочисленного в подледный период.
In March 2019, we studied the taxonomic composition, vertical and horizontal distribution of under-ice zooplankton in Lake Pleshcheyevo and revealed that its quantity (abundance 11.5–13.8 thous. ind./m3, biomass <0.1 g/m3) was much lower than in the same season of 1980–1990. The cryophilic species Cyclops kolensis dominated among crustaceans. An increase in the share of representatives of the genus Synchaeta (12–27% of the total abundance of rotifers) was also noted. At the same time, previously dominant during the under-ice period Eudiaptomus graciloides demonstrated the reduced abundance.

Abstract

OBJECTIVE
To conduct a retrospective multi-institutional study reporting short- and long-term outcomes of adrenalectomy in patients presenting with acute hemorrhage secondary to spontaneous adrenal rupture.

ANIMALS
59 dogs and 3 cats.

METHODS
Medical records of dogs and cats undergoing adrenalectomy between 2000 and 2021 for ruptured adrenal masses were reviewed. Data collected included clinical presentation, preoperative diagnostics, surgical report, anesthesia and hospitalization findings, histopathology, adjuvant treatments, and long-term outcome (recurrence, metastasis, and survival).

RESULTS
Median time from hospital admission to surgery was 3 days, with 34% of surgeries being performed emergently (within 1 day of presentation). Need for intraoperative blood transfusion was significantly associated with emergent surgery and presence of active intraoperative hemorrhage. The short-term (≤ 14 days) complication and mortality rates were 42% and 21%, respectively. Negative prognostic factors for short-term survival included emergent surgery, intraoperative hypotension, and performing additional surgical procedures. Diagnoses included adrenocortical neoplasia (malignant [41%], benign [12%], and undetermined [5%]), pheochromocytoma (38%), a single case of adrenal fibrosis and hemorrhage (2%), and a single case of hemangiosarcoma (2%). Local recurrence and metastasis of adrenocortical carcinoma were confirmed in 1 and 3 cases, respectively. Overall median survival time was 574 days and 900 days when short-term mortality was censored. No significant relationship was found between histopathological diagnosis and survival.

CLINICAL RELEVANCE
Adrenalectomy for ruptured adrenal gland masses was associated with similar short- and long-term outcomes as compared with previously reported nonruptured cases. If hemodynamic stability can be achieved, delaying surgery and limiting additional procedures appear indicated to optimize short-term survival.

Published: September 2023

Abstract

Study aim: This study aimed to determine and compare the ‘optimum power load’ in the hexagonal (HBDL) and straight (SBDL) bar deadlift exercises.

Material and methods: Fifteen novice strength-trained males performed three repetitions of the HBDL and SBDL at loads from 20–90% of their one-repetition maximum (1RM). Peak power, average power, peak velocity, and average velocity were determined from each repetition using a velocity-based linear position transducer.

Results: Repeated measures ANOVA revealed a significant effect of load for HBDL and SBDL (all p < 0.001). Post-hoc analyses revealed peak power outputs for HBDL were similar across 50–90% 1RM, with the highest peak power recorded at 80% 1RM (1053 W). The peak power outputs for SBDL were similar across 40–90% 1RM, with the highest peak power recorded at 90% 1RM (843 W). A paired sample t-test revealed that HBDL showed greater peak power at 60% (Hedges’ g effect size g = 0.53), average power at 50–70%, (g = 0.56–0.74), and average velocity at 50% of 1RM (g = 0.53). However, SBDL showed greater peak velocity at 20% (g = 0.52) and average velocity at 90% of 1RM (g = 0.44).

Conclusion: Practitioners can use these determined loads to target peak power and peak velocity outputs for the HBDL and SBDL exercises (e.g., 50–90% 1RM in HBDL). The HBDL may offer additional advantages resulting in greater peak power and average power outputs than the SBDL.
