Objective: Distress tolerance and self-compassion play a significant role in mitigating the harm caused by the experience of infidelity. This study compares the effectiveness of cognitive behavioral therapy (CBT) and compassion-focused therapy (CFT) in improving distress tolerance and self-compassion among women who have experienced marital infidelity. Materials and Methods: This quasi-experimental study employed a pre-test, post-test, follow-up design with a control group. The study population included women who had experienced infidelity by their spouse and sought counseling and psychotherapy services in Tehran in the year 2021. From this population, using purposive sampling, 45 women were selected based on the study's criteria and randomly assigned to two experimental groups and one control group (15 per group). The first experimental group received cognitive behavioral therapy, and the second received compassion-focused therapy. The control group did not receive any intervention. Data were collected using the Distress Tolerance Scale (Simons & Gaher, 2005) and the Self-Compassion Scale (Neff, 2003). Data were analyzed using repeated measures analysis of variance and SPSS software version 22. Findings: The results showed that both distress tolerance and self-compassion scores in the cognitive-behavioral and compassion-focused therapy groups were higher in the post-test compared to the pre-test (p<0.01). Furthermore, a comparison of the two experimental groups revealed no significant difference in scores of distress tolerance and self-compassion between the groups. Conclusion: It can be concluded that both cognitive-behavioral therapy and compassion-focused therapy were equally effective in improving distress tolerance and self-compassion among women.

Authors: Wang Zhiwei , Wei Yu , Liu Hongyuan , Chen Feng
Published: April 2024

[Objective] Biochar was used as a soil conditioner to analyze the effects of biochar on soil moisture, conductivity and nutrients in new cultivated land and agricultural runoff nutrients in the Yellow River Basin. [Methods] In Caoxian County, Heze City, Shandong Province, a field experiment was conducted with rice as the test crop, and the biochar application rates were set at 0 t/hm2 (CK), 4.5 t/hm2 (C1), 9 t/hm2 (C2) and 13.5 t/hm2 (C3) treatments were used to determine soil water content, electrical conductivity, soil nutrients and agricultural runoff nutrients under different treatments, and to analyze the effects of biochar on rice yield, as well as its correlation with soil physicochemical properties and agricultural runoff nutrients. [Results] Compared with the control, the application of biochar had a significant effect on soil water content, and the increase of soil volume water content decreased with the increase of biochar application amount. In August and September, the soil conductivity treated by C1 and C2 was significantly higher than CK, and there was no significant difference in the rest of the rice growth period. The application of biochar could promote the absorption and utilization of soil nutrients, but had no significant effect on soil pH. C1 and C2 treatments generally increased the nutrient content of farmland regression water, and C3 treatments generally reduced the nutrient content of farmland regression water. The application of biochar could increase the yield of rice, especially the C2 treatment, which was 8.49%. The correlation analysis showed that soil total phosphorus, total potassium and available phosphorus were significantly positively correlated with rice yield, and soil nitrate nitrogen and SO2- 4 contents were significantly negatively correlated with rice yield. The total nitrogen, total potassium and nitrate nitrogen in agricultural runoff were significantly positively correlated with rice yield. [Conclusion] The application of biochar can increase soil moisture, affect soil nutrients and electrical conductivity, and help to increase nutrient content in new created cropland in the Yellow River basin, and can be used as a soil amendment for new created cropland in the Yellow River basin. The recommended application amount is 9 t/hm2.

Published: April 2024

The research on the early warning method of flash floods serves as an important groundwork for the prediction and early warning of flash flood disasters. Being restricted by various objective factors such as lack of data and complicated formation mechanism of flash flood disasters in small watersheds, accurate and targeted early warning has consistently been a weak link within the flash flood control system. In this regard, focusing on a series of problems, such as "short risk forecasting period", "frequent missing and false reports" and "poor early warning accuracy", this research explores a hierarchical partition management system that fulfills the demands of early warning based on the analysis of watershed lag time and risk situation. Meanwhile, based on the comprehensive consideration of the characteristics of various multi-source early warning data, such as meteorological forecast rainfall and monitoring rainfall water level, this research proposes corresponding early warning modes for different types of early warning objects. On these grounds, this research applies the proposed early warning system to Xiaguan Creek in Shangyu District, Zhejiang Province. Relevant findings indicate that the effective extension of the forecasting period, coupled with the reduction of the phenomenon of "missing and false reports", provides scientific support for the early warning and transfer decision related to flash floods.

Authors: Rui Zilong , Zhou Kuibin , Dong Ruixing , Shi Xia
Published: April 2024

Double jet flames are commonly observed in the energy industry. A facility consisting of a double jet flames apparatus, was designed to experimentally simulate the interaction of double jet fires with different spaces and nozzle diameters. It has been found that the exit momentum, nozzle diameters and nozzle spacing significantly affect the flame behavior. The experimental results show that the flame merging probability (Pm) of double jet fires with different nozzle diameters can be fitted with dimensionless parameters that couple the Froude number(Fr) and the distance between fire sources. Additionally, it has been observed that the difference in height between the two flames can be used as a parameter to determine the correlation between flame height and the distance to the nozzle center.

Authors: Zhu Junjie , Zhang Mingguang
Published: April 2024

In the event of a material leak in an atmospheric steel tank farm, it is likely to cause a fire and explosion, leading to an escalation of secondary accidents. According to the historical domino accident data to analyze the accident characteristics, the explosion phenomenon is common in atmospheric pressure steel storage tank accidents, and the coupling phenomenon is obvious. However, there is a dearth of research on multiple explosions in steel storage tank farms. This paper investigates the dynamic response of an atmospheric pressure storage tank under the coupling effect of simultaneous detonation of two explosive wave sources. With the help of finite element analysis software to establish a simplified model of the tank under the action of two sources of blast wave coupling, to explore the propagation law of the blast wave scenario and the dynamic response process of the tank. The deformation damage of the tanks by the angular size of the blast load is revealed, and the structural energy changes are analyzed. The study of the dynamic response of steel tanks under the dual-source explosion scenario can provide a theoretical reference basis for quantitative damage in realistic scenarios.

Authors: Chen Yating , Jiang Jiajia
Published: April 2024

Polymerization reaction is a strong exothermic reaction that is prone to thermal runaway accidents. To prevent thermal runaway accidents, a styrene thermal polymerization reaction model is established by using computational fluid dynamics (CFD). The failure of stirring speed, cooling temperature of cooling jacket and cooling flow rate during the reaction process are simulated to explore the impact of runaway scenarios on reaction temperature rise and hot spot distribution. The results show that under the conditions of stirring speed of 160 r/min, cooling temperature of 155 ℃ and cooling flow rate of 3.2 m/s, the average temperature of the reaction system is lower and there are fewer hot spot areas, which reduces the possibility of thermal runaway accidents. The monitoring point position that best represents the average temperature of the entire reaction system is located at or above the top one-third of the liquid level.

Authors: Cheng Dan , Li Gang , You Fei
Published: April 2024

To enhance the thermal stability and flame retardancy of cotton fabrics, a hybrid sol was prepared by using silica (SiO2) sol, calcium hypophosphite (CaHP) and chitosan (CS), then finished on the surface of cotton fabrics through dipping-baking (drying) method. The results show that the CaHP-CS and SiO2 are successfully attached to the cotton fabric surface. Remarkably, the limiting oxygen index (LOI) value of the CaHP-CS-SiO2@COT was 31.30 % ( the highest of all samples). In the cone calorimetry test (CCT), the study revealed that the CaHP-CS-SiO2@COT has the lowest peak heat release rate (PHPP), fire growth rate (FGR) and CO2/CO. Its flame retardancy is mainly enhanced by the SiO2 (provides a gel coating with dimensional structure to block the transmission of oxygen and heat, CaHP (promotes cotton cellulose to dehydrate and form aromatic chars) and CS (dilute gaseous products and cool down heated areas).

Authors: Yang Haoqing , Zhuang Bailiang , Liu Yongyue , Li Jingkun
Published: April 2024

A novel room temperature-thermal curing process was proposed to fabricate the Fe/epoxy composite easily and rapidly. The effect of thermal curing on the microstructure and mechanical properties were investigated. The results show that the thermal curing leads to the coarsening of Fe phase and the dense of Fe/epoxy interface. The average diameter of Fe increased from 36.03 μm to 64.91 μm after thermal curing, leading to the microstructure evolved from the island shape to the quasi reticular structure. The voids in the Fe phase and cracks along the phase boundary in the Fe/epoxy composite disappeared under the effect of diffusion. The tensile strength increased from 13.14 MPa to 53.72MPa and the elongation increased from 5.86% to 8.18% after thermal curing, with the improvement of 308.8% and 39.6%, respectively. The combination of brittle fracture in Fe and the crack elongation along the interface of Fe/epoxy improve both the strength and the plasticity of the Fe/epoxy composite. The Fe grains sustain fine with average size of 0.49 μm, contains abundant low-angle grain boundary (LAGBs) and deformed grains, but the density of dislocation and the value of texture are extremely low.

Authors: Wang Ziyi , Wei Xiangshu
Published: April 2024

The development of the Internet has given birth to a new type of promotion mode, and the selection of promotion agents has become a hot issue. The influence index of the agent itself and the type of its association structure become the key factors affecting the degree of product promotion. In this study, we analyze different types of influencers and their community structure in social networks, study the influence of influencers' community structure and influence on information dissemination, and try to find out the agent selection strategy to obtain the highest promotion efficiency under the lowest budget. Based on these findings, this paper proposes an agent selection strategy for product promotion that integrates influencer type and association structure. The strategy suggests that firms first identify the social network structure of their target market and then select the combination of influencers that maximizes the effect of information dissemination. The findings of this study provide a new perspective and methodology for enterprises to promote their products in social networks, which helps them to utilize social network resources more effectively and enhance the effectiveness and efficiency of product promotion.

Authors: Li Yuchen
Published: April 2024

With the trend of decentralization, fragmentation and popularization of media communication, “micro-short plays”, which integrate the characteristics of short videos and TV dramas, emerge at the opportune moment. They have since developed a unique narrative system and aesthetic style. With the Douyin platform as an example, the narrative characteristics of micro-short plays are closely related to the platform and media characteristics of short videos. As for narrative objects, micro-short plays present a weakening of the environment and the focus of characters. They pursue a “fast-paced” and “refreshing” structure and plot, themed by both topicality and network IP.

Published: April 2024

Cluster headaches affect 0.1% of the population and are four times more common in males than in females. Patients with this condition present with severe unilateral head pain localized in the frontotemporal lobe, accompanied by ipsilateral lacrimation, conjunctival injection, nasal congestion, diaphoresis, miosis, and eyelid edema. Recently, the first genome-wide association study of cluster headaches was conducted with the goal of aggregating data for meta-analyses, identifying genetic risk variants, and gaining biological insights. Although little is known about the pathophysiology of cluster headaches, the trigeminovascular and trigeminal autonomic reflexes and hypothalamic pathways are involved. Among anti-calcitonin gene-related peptide monoclonal antibodies, galcanezumab has been reported to be effective in preventing episodic cluster headaches.

Published: April 2024

Lecaniodiscus cupanioides Planch (ex. Benth) is effective in treating burns, fevers, and inflammatory conditions. This study investigates the toxicity effects of the aqueous leaf extract (ALE) of L. cupanioides and its effect on stress-induced ulcers in animal models. The plant was collected and a 1:30 (g/ml) plant powder/solvent ratio was extracted using an ultrasonic bath at 50 °C for 45 min. Up-and-down procedure was used for acute toxicity. During subacute toxicity testing, a total of 20 mice were divided into four groups of five animals each. While group 1 served as control, groups 2, 3, and 4 received 250, 500, and 1000 mg/kg of the extract daily for 21 days. On day 22nd, animals were sacrificed and samples were collected for hematology, biochemical, and histological analyses. In the stress-induced ulcer activity, male albino mice were randomly separated into 5 groups of 5 animals, treated with the test drug, and then dissected after being stressed using the water immersion model. LD50 was > 5000 mg/kg, and in biochemical examination, there was a significant decrease in the ALP level at medium and high doses (p value < 0.05) and non-significant alterations in the values of urea, creatinine, alanine aminotransferase (ALT), aspartate aminotransferase (AST), body weight and hematology parameters (p > 0.05). The histology results showed no evidence of liver and kidney toxicity. In conclusion, aqueous leaf extract of L. cupanioides was safe following a single dose (at 5000 mg/kg) and following repeated doses for 21 days (at 250, 500, and 1000 mg/kg). This study demonstrated that the extract had a significant effect on stress-induced ulcers at various dose levels when compared to the control (native, negative control, and omeprazole). The animals treated with 200mg/kg and 400mg/kg of the extract showed a significant increase in ulcer score, ulcer index, ulcer severity, and total acidity (p < 0.05). The ulcer protection ability of the aqueous plant extract was dose-dependent.

Pigment compositions in Siberian early Upper Paleolithic complexes
Authors: Lbova Liudmila
Published: April 2024

Cultural assemblages associated with archaic forms of Homo sapiens in Siberia appeared around 40 000 – 50 000 years BP, revealing the evidence of the modern behavioural complex and use of various pigments. Multi-element composition of pigment materials appearing on some Early Upper Palaeolithic objects, which was obtained using SEM-EDX analysis, showed differences in the use of various natural ingredients in the territories of Southern Siberia (as Kara-Bom, Denisova cave (11), Malaya Syya, Khotyk-3, and Kamenka). Microscopic examination and identification of traces using low- and high-power microscopes revealed the presence of pigment and pigment’s composition on the surface of the personal ornamentations, and also as a natural haematite with trace of using. Composite pigments and a wider colour spectrum, including blue and green colours, replace the use of natural pigments such as goethite, hematite, limonite, colorful clays in collections of the early stages of the Upper Palaeolithic. The use of natural pigments in culture has two aspects: utilitarian, for everyday and symbolic. Household use of pigments, especially ochre, is known from ethnographic materials as antiseptic, adhesive material, skin softener, and addition for food.

A coconut climber mechanism was subjected to Finite Element Analysis (FEA) to improve its overall design and analyze its strength characteristics. The von Mises stress, total deformation, and factor of safety were evaluated using static structural analysis for the seat and pedal assemblies of the mechanism. The design has a minimum yielding factor of safety of 7.03 for the seat assembly and 12.09 for the pedal assembly. If aluminum is used as an alternative to steel, the prototype's weight can be reduced to at least 64.56% without compromising its strength properties. The weight reduction by using aluminum is expected to reduce the effort required to use the improved designs. This study also demonstrated a robust methodology of exploring design alternatives without fabricating actual prototypes, leading to a more cost-effective design process. It is recommended that other topologies and materials be further explored to improve the design of the coconut climber mechanism.

Based in the Visayas State University, Philippines, the germplasm collection of the Philippine Root Crops Research and Training Center (PhilRootcrops) is home to several varieties that have not been fully characterized for their potential use in the production of functional foods. This study evaluated the compositional properties, amylose/amylopectin ratio, and glycemic index of flour and starches of 10 varieties of cassava (Manihot esculenta Crantz), sweet potato (Ipomoea batatas L. (Lam)), and taro (Colocasia esculenta L. Schott); 8 varieties of yam (Dioscorea alata L.); and 5 varieties of arrowroot (Maranta arundinacea L.), which was the recommended varieties of the National Seed and Industry Council (NSIC). The total starch as well as the amylose/amylopectin ratio of the starch component was determined using Megazyme assay kits, and the glycemic indices were predicted through enzymatic in vitro starch hydrolysis. Results revealed significant (p < 0.05) varietal variations on flour and starch yield, dry matter, crude protein, crude fiber, amylose/amylopectin ratio, and glycemic index. Among these crops, sweet potato was found to have the highest amylose contents, while taro and arrowroot showed lower glycemic indices. These profiles can serve as fundamental information for processors to develop new products that capitalize on these unique properties.

This study was conducted to determine the physico-chemical characteristics of ensiled cassava (Manihot esculenta Crantz) and sweetpotato (Ipomoea batatas L. (Lam.)) foliage with or without additives molasses and rice bran. Six treatment combinations were from two crop species (cassava and sweetpotato) and three additives (without additive, 10% molasses, and 10% rice bran). The physical (color, odor, texture) and chemical characteristics (pH, total soluble sugars, Flieg point, dry matter, organic matter, ash, crude protein, NDF, ADF, hemicellulose) of the samples were evaluated following standard procedures. Fermentation kinetics of cassava foliage silage and ruminal in situ DM degradability of cassava foliage silage were evaluated for 3, 6, 12, 24, 48, and 72 h using cannulated cattle. Results showed that cassava foliage (CF) and sweetpotato foliage (SF) silages with molasses had the lowest pH of 3.82 and 3.80, respectively due to high TSS values of the samples. CF had the highest crude protein (19.06%) compared to SF silage (11.61%). Moreover, CF had low fiber fractions (NDF and ADF) resulting in a high effective dry matter degradability (74.73%) of the silage. Results on silage quality, nutritive value, and dry matter degradability evaluation proved the potential of cassava foliage silage with molasses as an alternative high protein feed for ruminants.

Biochar is a carbon (C) rich material that improves soil quality, increases crop yield, and is produced from biomass pyrolysis under a limited oxygen environment. An experiment laid out in a split-plot, a completely randomized design (CRD) and was conducted to investigate the growth responses of corn-to-corn cob biochar (CCB) (15 t ha-1), and corn husk biochar (CHB) (15 t ha-1) in a Lipa clay loam soil (Typic Eutrudepts) applied with organic fertilizer (OF) (10 t ha-1) and inorganic fertilizer [recommended rate (RR):120 N;60 P2O5-60; K2O per ha]. The results showed that CCB and CHB are rich in macro- and micro-essential elements. The Brunauer-Emmett-Teller (BET) analysis showed the high average surface area, high pore radius, and pore volume of biochars. The field emission-transmission electron microscopy (FE-TEM) and X-ray energy dispersive spectroscopy (EDS) showed a very high concentration of C (88 – 90%) and other elements (Cu, Na, K, Cl, S, Si, P, Ca, O) for the biochar. The CCB and CHB applied with organic and inorganic fertilizers improved the pH, EC, and nutrient status of the clay loam soil. This was evident in the enhanced growth of the plants (corn ear biomass, root biomass, and plant height) and increased leaf chlorophyll concentration. The CCB and CHB with organic and inorganic fertilizer applications are recommended for clay loam soil as they improve both the soil health and the plant growth.

Climate change is leading to severe heat waves in India, affecting a large vulnerable population and impacting their health and well-being. The recent adaptive thermal comfort research for Indian climates suggested that the people living in residential buildings can adapt to indoor temperatures upto 35 ℃. The Jain ascetics in India have been leading their life without the use of electricity for hundreds of years, irrespective of the temperatures. In this study, thermal comfort surveys with 20 monks and nuns were carried out during summer for the composite climate of Delhi. 90% of the subjects expressed acceptability of the thermal conditions while the indoor operative temperatures varied between 35 ℃ and 40 ℃. This study should offer hope to people globally that if we can gradually adapt to the rising temperatures, we may be able to move on with our lives without affecting our comfort or health.

Published: April 2024

This paper evaluates the current model curricula in India for architecture and engineering colleges as well as education policy documents that will influence the coursework taught across the country to determine if the undergraduate and post-graduate education system is aimed at creating future professionals who can respond to India's Nationally Determined Contributions and net-zero by 2070 goal. It uses literature review and survey data to identify gaps in graduate attributes and competencies that result from these curricula and policy documents. While over fifteen years of codes and rating systems, and longer for industry-led practices, have introduced standards and best practices, the market has not moved towards future-proof net-zero buildings. The findings show that the model curricula do not address climate change and that comprehensive frameworks, as well as transformative education at scale, are being done through other programs like Solar Decathlon India (SDI).
Optimizing Urban Morphology to Mitigate Urban Heat Islands: A Case of Hyderabad
Authors: Pothamsetty Amuktamalyada , Chundeli Faiz Ahmed
Published: April 2024

Urbanization, changing urban geometries and surfaces, forms hotspots called urban heat islands (UHI). Several studies have been conducted to understand its cause, intensity, and impact on urban microclimate. The current study attempts to assess the impact of the urban morphology of multiple residential urban blocks in Hyderabad on urban heat island intensity. The study explores the possibility of UHI mitigation by modifying morphology constructed on policy measures like zoning regulations. Six urban residential blocks under the city's peri-urban belt are studied for their morphology and microclimate. Field study, 2D building database, and satellite imagery are used to develop urban built geometry of the blocks. The microclimate, i.e., air temperature and wind speed, is determined using a numerical model, ENVI-met. The simulated microclimate data is used to compute UHI intensity based on reference climate data of an urban block at the time of the investigation. The urban morphology is then modified to reduce UHI intensity. The modified urban geometry with a significant reduction in UHI intensity is used to suggest planning/design recommendations through zoning regulations. Further, the paper reinforces the significance of the correlation between UHI and urban morphology, which can be regulated through zoning.

Published: April 2024

Optimizing operational energy in buildings can increase the significance of embodied energy and associated carbon emissions. Promoting low embodied energy materials and construction processes is crucial for achieving low-carbon development while reducing operational energy. However, accessing reliable embodied energy data for construction materials in India poses a major challenge for conducting Life Cycle Assessments (LCA) to quantify the environmental impact. The proprietary nature of these datasets limits their availability in LCA studies, leading to uncertainties in building LCA results. Thus, this study aims to develop a construction material embodied energy database in India. A uniform data collection framework adapted for the building and construction sector and confidence level measurements for the embodied energy datasets will be used. This database will help reduce uncertainty in LCA studies and support informed decision-making.

Published: April 2024

The paper investigates how residential loads in India contribute to grid peak load and how to manage such peaks. Algorithms that process smart meter data from residential loads and compute attributes that capture their contribution to the system peak are devised and demonstrated in the paper. Specifically, a distribution system is considered based on a study on households in Pune, India. To enhance the household dataset for analysis, a synthetic data generation technique is employed. The algorithms developed here are applied to this system to showcase their capabilities. Results show how simple attributes such as peak amplitude and peak duration can extract sufficient information to ensure households that contribute to system peak are appropriately identified. Moreover, these attributes offer insights into appliance ownership, supporting the development of effective DR programs. A demonstration of how shifting of individual peaks can significantly impact system peak is also provided. The results lay the foundation for designing meaningful DR programs leveraging the smart meter data.
