Investigation of the Impact of Different Earthquake Zones on Irregular Plan Buildings Managed by Belt Wall
Authors: Jambhulkar Maitrey , Tenpe Dr. Ashwini
Published: June 2024

Abstract: The least sturdy areas of a structure sustain damage first during an earthquake. Failures in the structure's mass, rigidity, and shape are the root cause of this weakness. Structures are composing of structures with discontinuities, like this one. The majority of urban infrastructures are unstructured systems. An unequal distribution of mass, strength, and stiffness within a building could result from structural irregularities. One of the primary causes of structural failures and earthquakes are abnormalities in mass, stiffness, plane, torsion, etc. As a result, it is essential to consider how all four of these irregularities affect a structure's performance. These buildings differ from typical buildings in their dynamic qualities because of variations in mass and stiffness with height. The study design are more difficult when the building is construct in a seismically active area. In this research work investigate about the impact of different earthquake zones on irregular plan buildings managed by belt wall. For modeling and analysis work use ETABS 2016. In this work select G+11 building for study that plan irregularity. Perform response spectrum analysis in all four zones of earthquake. Study their displacement, bending moment, story drift, shear force and base reactions. After complete the analysis work all parameters are controlled by belt wall and compare controlled and uncontrolled parameters.

Paranoia, (Para)cinema, and the Right-Wing Mindset: Making Sense of My Son Hunter
Authors: Frykholm Joel
Published: June 2024

This article aims to make sense of My Son Hunter (The Unreported Story Society and Breitbart News, 2022; dir. Robert Davi). The first part of the analysis discusses My Son Hunter as an example of right-wing counter-cinema that tries to simultaneously tap into the cultural prestige associated with feature filmmaking and provide niche audiences with “paracinematic” pleasures. The second part of the analysis explores cinematic form and filmmaking techniques in My Son Hunter, demonstrating how the movie extends a promise of “truth” via an affective bombardment that draws on melodrama and paranoid fiction as well as the flexible modes of docudramatic approximation. The overall effect is to make logic and argumentation superfluous, which is indicative of how the film can be regarded as both symptomatic and productive of a “post-truth” condition.
Crises in the Arctic: Upheavals in the Memoir of Josephine Diebitsch-Peary
Authors: Juncker Clara
Published: June 2024

In My Arctic Journey: A Year among Ice-Fields and Eskimos (1894), Josephine Diebitsch-Peary documents her experiences during the North Greenland Expedition of 1891–92, which began ominously when her husband, the famed Arctic explorer Robert E. Peary, broke his leg aboard the Kite and was carried to the expedition headquarters near the mouth of MacCormick Fjord. As the first white woman in the Arctic, Diebitsch-Peary faced numerous crises, torn as she was between True Womanhood ideals and desires for hunting and exploration. She navigated internal and external upheavals, depicting the Arctic landscape and native disputes, and vacillating between biased descriptions and identification with Inughuit women. Additional crises included the disappearance of mineralogist and meteorologist John M. Verhoeff and the pressures of her husband’s ambitions. Despite these challenges, she actively participated in the expedition, grappling with traditional role expectations and the demands of polar exploration. Her memoir reflects the personal, national, and international costs of a contested icescape, revealing the struggles she overcame and those she did not.
Trump's Playbook of Electoral Manipulation: An Interplay of Manipulation Tactics in a Longstanding Democracy
Authors: Lindén Maria
Published: June 2024

The attempt by former President Donald Trump to manipulate the United States’ 2020 presidential elections is a salient example of how electoral manipulation has changed to adapt to the new political and societal context that marks present-day elections. This highlights the need for a novel approach to help us better understand electoral manipulation, which is becoming increasingly common all over the world. This article addresses this need by presenting a novel framework for examining electoral manipulation in the United States in the 2020s. A novel feature of the framework is a focus on the interplay between different manipulation tactics. It identifies nine electoral manipulation tactics that interact with and reinforce each other: breaking democratic norms, disinformation, gerrymandering, voter suppression, hacking and leaking, collusion with foreign states, intraparty pressure, intimidation and violence, and corrupting state and government institutions.
The use of Fuzzy Logic Controller and Artificial Bee Colony for optimizing adaptive SVSF in robot localization algorithm
Authors: Suwoyo Heru , Hajar Muhammad Hafizd Ibnu , Indriyanti Prastika , Febriandirza Arafat
Published: June 2024

The objective of solving feature-based localization problems is to estimate the path of the robot referring to a given map. Thus, it is not surprising that robust estimators such as Smooth Variable Structure Filter (SVSF) are often used to handle this problem. Basically, its use is highly dependent on an accurate system model and known statistical noise. Where neither of these are available by definition. Therefore, the conventional way is not recommended and the use of an adaptive filter approach can be involved. Based on this and although only partially, Innovation Adaptive Estimation (IAE) has been considered to have a positive influence on improving the performance of the estimator. But not infrequently the solutions offered by this approach also lead to divergences due to unmapped dynamic conditions. Moreover, in this proposal, IAE is enhanced by applying Artificial Bee Colony-Tuned Fuzzy Logic. The hope is that there is quality control for the process noise covariance Q and R measurements by updating them based on the output of this ABC-Tuned FLC.

A traffic accident is an unexpected and inadvertent road event involving a vehicle with or without other road users that results in human injuries and possibly property damage. This study identifies and analyses the characteristics of Indonesian and Malaysian road traffic incidents. The method used was the identification of crash data coordinates and the Equivalent Accident Number (EAN) score per road segment. Accident characteristics are based on the type of road traffic accident, and collision is the most common type of accident. Speed data of two vehicles, cars and motorcycles, was collected through the test driver method by using the same vehicles for cars and motorcycles and following their normal driving habits. From the analysis results, some factors causing accidents on the Bekasi Narogong Road Section are the lack of traffic signs, road surface conditions, and lack of clear road markings. While on the FT050 Johor federal road, every kilometre per segment and along the segment, motorcycles are faster than cars in terms of speed.
Analysis of floodwater: A Case Study of the Tukad Buluk Poh River
Authors: Hidayat Acep , Praptoyo Riska Dwi , Isradi Muhammad , Suprapti Suprapti
Published: June 2024

One of the main causes of flooding is the disruption of river flow due to silting or narrowing of the river basin. The high volume of water in the rivershed will overflow and cause flooding in the surrounding area of the river. The object of this research is the Tukad Biluk Poh River, a river in the Jembrana district, Bali, which has 28 km long and empties into the Indian Ocean. The study aims to measure a flood water level limit at the river bridge that crosses the National Highway Gilimanuk-Denpasar so flooding on that section can be avoided. This quantitative descriptive research analysis uses the Nakayasu HSS (Synthetic Unit Hydrograph of Nakayasu) method for a while in 2, 5, 10, 25, 50, 100, 200, and 1000 years. Next, a hydraulics analysis to determine the flood water level limit uses the HEC-RAS model and results in MAB heights for a similar period. The research results revealed the height at the pavement section and the bottom of the girder section. At the end of this paper, the height of bridge that needs to be elevated at the bottom of the bridge's upper structure and a guard height for a certain repeat time are discussed. Therefore, it is believed that the research outcome will make an important contribution to the local government in issuing the Tukad Biluk Poh rivershed policy.

Enriching Students’ Cross-Cultural and Multilingual Communication: The Serious Play Approach Utilizing Playmobil Pro Figures
Authors: Meletiadou Eleni
Published: June 2024

Playmobil pro is an innovative modelling kit for adults that encourages creative thinking in the university/workplace. International multilingual students often disclose that they have little opportunity to develop their intercultural awareness, and cross-cultural and multilingual communicative competencies while engaging in meaningful activities that foster sustainable content and language learning. In the present study, 35 students were involved in two Playmobil pro workshops. They worked individually to present themselves to their peers, referring to their cultural background. They then worked in groups to explore intercultural differences among people working for organizations operating in the UK and another country of their choice and offer recommendations to help organizations avoid cross-cultural conflicts. The aim was to actively engage students to work on their final assignment and develop their intercultural awareness and cross-cultural communicative skills. This case study used a qualitative design and explored students’ attitudes by asking them to write a short anonymous report at the end of the implementation and provide anonymous feedback via Mentimeter after each workshop. The lecturer also kept notes in the form of a diary during this implementation. Thematic analysis was used to analyse the data which revealed that Playmobil pro facilitated intercultural communication in the post-COVID-19 era as students seemed to be unwilling to work with their peers in face-to-face classes, possibly suffering from trauma. However, learners confessed that they needed more time, support, and artefacts to fully present their ideas and thoughts. Recommendations for the effective implementation of Playmobil pro with multilingual students will be offered.

Published: June 2024

Obstacles related to the continuous cropping of sweetpotato (
Ipomoea batatas (L.) Lam.) restrict its intensive production.
However, the effects of continuous cropping on soil properties and/or
the rhizosphere microbial community are largely unclear. In this study,
we analysed changes in rhizosphere soil chemical properties and
microbial communities of sweetpotato across different cultivation years.
We observed that the microbial diversity and complexity of the fungal
ecological network in rhizosphere soils of sweetpotato were decreased
after 5 years of continuous cropping, with significant enrichment in
Sphingobium, Gemmatimonas, Volutella, and
Neoidriella. Tuber yield, soil pH, and available potassium (AK)
content were significantly reduced after continuous cropping, with the
soil microbial community having the highest correlation with pH, AK, and
ammonium nitrogen (NH -N).
Specifically, soil pH and AK were positively correlated with
Bacillus and Gaiella, and negatively correlated with some
plant-pathogenic fungi ( Volutella and Neoidriella), while
NH -N showed the opposite trend. In
addition, soil pH, AK, and the relative abundance of Bacillus
were positively correlated with tuber yield, while Volutella
showed the opposite trend. In summary, the continuous cropping of
sweetpotato negatively affects rhizosphere soil health, resulting in
imbalanced soil fertility and increased abundance of pathogens. These
results improve our understanding of factors driving obstacles faced
with the continuous cropping of sweetpotato, enabling future studies and
the development of technologies to overcome these obstacles.

We report the first provincial records of the genus Dolichoderus in Saskatchewan, represented by two species: Taschenberg’s Long-necked Ant (Dolichoderus taschenbergi) and Mary’s Long-necked Ant (Dolichoderus mariae). These species are previously known from eastern Canada and the eastern United States. The new discoveries fill in the range for D. taschenbergi, which has previously been found in Alberta and Manitoba, but has not been reported from Saskatchewan, and they represent a significant westerly range expansion of D. mariae, which has previously been reported in southeastern Manitoba and Ontario.
Torpor may facilitate opportunistic predation of live-trapped small mammals: a cautionary note
Authors: Jung Thomas , Kenney Alice , Krebs Charles
Published: June 2024

Small mammals are often key components in ecological monitoring programs, and live trapping is often used to obtain small mammal density estimates or other metrics. However, an aspect of such trapping that has received little attention is opportunistic predation of captured animals. Here, we report a Common Raven (Corvus corax) preying on a deermouse (Peromyscus spp.) after it was released from a live trap. The mouse was torpid when removed from the trap. The raven preyed on the deermouse right after it was released, likely because the mouse had not yet fully aroused from torpor and was not able to find adequate shelter or evade the raven. Best practices to avoid similar occurrences include passively warming the animal before releasing it or returning it to the trap to arouse from torpor in safety. Our observation further highlights the need for researchers to be vigilant about opportunistic predation of small mammals captured and released from live traps and to take actions to mitigate the risk, especially if the mammals are exhibiting signs of torpor.

Despite of positive impacts of the earnings management on the business purposes, many businesses have been suffered due to the audit failures as a result of aggressive earnings management. Therefore, the study on true reflection of earnings management, the controlling factors and how aggressively manipulated earnings quality can be mitigated are the areas of concern these days. For the estimation of earnings management, performance matched discretionary accruals model has been implemented as this model has been identified as the best explanatory models. Thereafter, this research has accumulated the sector-wise earnings management to identify the impact of sectors on the sectorial earnings management. There are eleven different industries involved in the research while four of them have revealed that the managers from certain sectors have got involved in the aggressive earnings management. Further, this research has investigated the impact of the attributes of the corporate governance on the sector-wise earnings management. the variables of corporate governance like managerial ownership, block-holders, institutional ownership and non-executive directors’ fees have significant impact on sector-wise earnings management where other variables like board meeting, board size, number of female members on the board, board independence have not been identified as they have significant impact on controlling earnings management. Univariate and multivariate methods are used to demonstrate the results and to establish the inferences of the outcomes of the research. The use of coefficients (β -value) and p-value are much prominent in this study.

Variant slip effects, aspect ratios and steady-state criteria in unsteady cavities with direct PDE simulation of eddies
Authors: Wong Hon Fei , Sohail Muhammad , Noor Noor Fadiya Mohd
Published: June 2024

Numerical simulations of an unsteady laminar lid-driven cavity Newtonian flow are executed to demonstrate the formation of eddies under different aspect ratios and steady-state criteria. A couple of nonlinear unsteady partial differential equations (PDEs) of Navier Stokes satisfying a set of boundary conditions is examined with both inclusions of no-slip and free-slip effects. Finite difference method (FDM) is employed to solve the vorticity-stream function using a self-developed Matlab® code embedded in a Graphical User Interface (GUI) to ease the cavity problem analysis by the end users. Four models are studied where Ansys Fluent® employing the Finite Element Method (FEM) is used to verify the present FDM steady-state results produced for the first model. It is observed that the value of stream function begins to drop and streamline distribution changes shape when e ≤ 10−5. Refrainment of merging of secondary eddies also happens when the free-slip boundary condition effect passes the threshold value. The Stretching effect with free-slip BC in the fourth model regulates the fluid dynamics to reach the entire cavity sufficiently with no room for eddy formation by increasing the slip length to an intense value. Free-slip simulates free surface applications in geophysical occurrences (river and glacier), spilling dynamics, ship hull designs, technologies of coating and fuel spraying/injection.

Authors: Chríbik Andrej , Majkút Andrej , Jančo Roland
Published: June 2024

In the scope of the green energy and climatic changes waste poses as a great resource as an alternative fuel or source for their production. This helps to decrease the need for fossil resources, as well as diversify energy production. This kind of waste utilization and mitigation therefore directly fits into latest legislation and green initiatives. This paper focuses on the influence of five synthesis gases with relatively high heating values on the internal parameters of the internal combustion engine intended for cogeneration. Measurements show that proportion of the hydrogen in the mixture has indirect influence on the combustion duration and also maximal pressure rise rate. Interestingly hydrogen proportion in fuel showed no direct influence on the maximal in-cylinder pressure. Higher CO to CH4 ratio reduced burn time and increased maximal combustion pressure with slightly decreased performance. Concentration of CH4 directly influenced volumetric LHV value of the mixture with subsequent influence on the IMEP and engine effective torque. Generally, operation of the engine at full load at 1500 min−1 on chosen mixtures compared to the runs on methane showed decrease of engine torque output of up to 13.4% and increase of the hourly fuel consumption from 1.56 for pure methane to maximally 3.87 kg.h−1 for measured gases. Lastly, for one of the fuels erratic engine operation was observed.

Authors: Srinivasa Rao Mallipudi , Ramanjaneyulu Siripurapu
Published: June 2024

The present work focuses on the influence of solid-state welding, namely, friction stir welding (FSW) and arc welding, namely, metal inert gas welding (MIG), on the mechanical characteristics of new lightweight 5 mm thick Al-Mg-Mn alloy plates with the addition of 0.4% Sc and 0.1% Zr. The alloys were fabricated using aluminium with 10% magnesium, aluminium with 2% scandium, and aluminium with 5% zirconium master alloys in combination with the Al-Mg-Mn alloy- with the help of a stir casting melting technique. The hardness, tensile strength, 3-point bend strength, impact strength and microstructure of the rolled Al-Mg-Mn alloy plates with the addition of 0.4% Sc and 0.1% Zr were examined. Both the mechanical properties of the FSW and MIG weld joints were compared with those of the non-welded plates. The strength of the non-welded Al-Mg-Mn-Sc-Zr alloy plates was greater, than that of the FSW and MIG weld joints. However, the friction stir welded joints exhibited the improved mechanical properties in comparison with those the MIG welded joints due to more refined precipitation. Compared with the non-welded Al-Mg-Mn-Sc-Zr alloy plates, the friction stir welded joint exhibited a 91.6% joint efficiency and a 63.8% metal inert gas welded joint.

This study used a central composite design (CCD) to evaluate how the independent attributes—sonication distance (X1), amplitude (X2), time (X3), & power (X4)—impacted two outcomes—droplet-size (Y1) & polydispersity index (PDI) (Y2). With the time-consuming & inefficient "changing one factor at a time" approach would have been an option for this multifactor optimization, but we opted against it since we wanted to be sure we had the best possible values. Here, a mathematical model of the combined influence of the processing elements led to the selection of a CCD, which is known to be significantly more dependable. Using a double emulsion technique, we created and fine-tuned a drug delivery system consisting of nanobubbles loaded with pemigatinib. Pemigatinib nanobubbles were studied for their shape, surface charge, and particle size to determine their physicochemical characteristics and found that they were spherical with the Zeta potential (ZP) and particle size of -25.3±2.98 & 38.53±2.14 respectively. Pemigatinib-loaded nanobubbles were also tested for their release behaviors and drug encapsulation effectiveness. Finally, we tried to study the anti-tumor activity and cellular absorption of poly (lactic-co-glycolic acid) nanobubbles-Pemigatinib in vitro.

Authors: Jhinjharia Divya , Singh Samvedna , Sahi Shakti
Published: June 2024

Type 2 Diabetes is a metabolic disorder that affects people worldwide. The G-protein coupled receptor (GPCR) known as free fatty acid receptor 4 (FFAR4) has been shown to be a potential therapeutic target for type 2 diabetes mellitus (T2DM)and complications linked to obesity. The present study focuses on the pharmaceutical role of FFAR4 and its potential agonists by predicting anti-diabetic responses, including insulin secretion, glucose uptake and calcium ion concentration levels. We identified differentially expressed genes and elucidated their role extensively through analysis of pathways, molecular mechanisms and linked biological processes. In the present study, a systems biology approach was implemented to establish an interaction network between FFAR4 and its driver’s such as CASR and NR1H4, that highlighted their significance as potential prognostic and therapeutic targets. A mathematical model incorporating biological events mediated by these proteins is studied and simulated using kinetics law reactions. Furthermore, the kinetic simulations were conducted to assess the impact of drug molecules, namely comp35, comp50, compN1 and compN2, on FFAR4 function. The findings reveal FFAR4’s potential as a therapeutic target for the treatment of type 2 diabetes mellitus.

Epilepsy, a neurological disorder characterized by abnormal brain electrical activity leading to recurrent seizures, affects approximately 1% of the Indian population, with higher prevalence in rural (1.9%) compared to urban (0.6%) settings. This interventional study conducted at a tertiary care hospital aimed to assess HRQOL among pediatric epilepsy patients using KINDL R questionnaires. Baseline data was collected from 110 pediatric patients, with two follow-up assessments conducted after interventions were implemented post the first follow-up. HRQOL was evaluated across three age groups: 3-6 years, 7-13 years, and 14-17 years. The study enrolled 110 patients and collected baseline data. Two follow-up assessments were conducted, and interventions were provided after the first follow-up. Following the intervention, HRQOL revealed positive changes in different age groups: 3-6 years (score changed from 17.37 + 2.31 to 20.79 + 4.10), 7-13 years (score changed from 53.29 + 3.96 to 58.88 + 5.68), and 14-17 years (score changed from 63.35 + 6.18 to 74.70 + 8.10). This study concludes that positive impact of pharmacist interventions on HRQOL among pediatric epilepsy patients. The findings underscore the effectiveness of pharmacist involvement in enhancing medication management and overall well-being. Further research could explore long-term effects and optimal strategies for improving HRQOL.

Published: June 2024

The purpose of the trial was to determine whether combination medication for type 2 diabetes mellitus offers better glycemic control than monotherapy. Subjects whose ages were more than 18 years and with glycated hemoglobin levels higher than 7.5% were enrolled. Among the 664 patients enrolled, 332 received monotherapy, while 332 were treated with combination therapy. The treatment groups received either vildagliptin + metformin combination therapy or metformin monotherapy. Vildagliptin, as an adjunct to metformin treatment, was to be evaluated for its safety and efficacy in reducing HbA1c levels from baseline. The study included individuals with a history of T2DM for 3 to 4 years who had been treated with either combination therapy or monotherapy for at least three months. Statistical analysis was done using SPSS software. As per the findings, it indicated that combination therapy led to a considerably greater reduction in glycated hemoglobin levels compared to monotherapy. Adverse events were also observed to vary significantly between the two treatment cohorts. Outcomes suggest that combination medication should be started earlier than monotherapy for superior glycemic control. Additionally, it was thought that the combo therapy had a positive safety profile.
