Published: October 2023

Road dust contributes significantly to air pollution by releasing fine particulate matter (PM) and other pollutants into the air, which can cause respiratory and cardiovascular problems and premature death. This dust is generated through the wear and tear of vehicle tires and road surfaces, as well as the accumulation of dirt and debris on the road, primarily from construction activities and cargo trucks carrying building materials. Wind, weather conditions, and vehicle movement play crucial roles in the distribution and concentration of these particles in the air. To address this issue, this paper focuses on identifying various variables that are connected to road dust operations and their interrelationships with air pollution variables, representing the dynamic pattern of the entire system. The paper proposes the establishment of a sustainable causal-loop model using system dynamics (SD) modeling in Vensim, connecting feedback mechanisms to effectively control the road dust concentration. Additionally, the paper suggests different policy interventions applied to the whole system to achieve optimized results. In the future, this research aims to convert and simulate the causal-loop model to a stock-flow model and compare the effectiveness of different policy interventions to further reduce road dust contributing to air pollution.

Published: October 2023

Canisters are used to store liquids such as oil, paint, liquefied glue, and so on. When a customer buys a canister of liquid, they expect the contents to be in pristine condition. The contents of the canister may become defective due to errors in manufacture, transportation, or unfavourable climatic conditions, and the unsuspecting client discovers this after breaking the seal. The vendor will not take the defective goods back after the seal has been broken. One such process that can be used to determine that the products in the canisters are in usable condition is non-destructive testing using ultrasonics. In this method, a transducer is used, which has a transmitter and a receiver. The transmitter is placed on one side of the canister, and the receiver is placed exactly opposite on the other side. Using this, the time taken for the waves to propagate from emitter to receiver (time of flight) is noted and compared with that of standard values. This process allows us to determine whether the contents of the canisters are in good condition or not. The measurements are carried out at three different locations, i.e., the top, middle, and bottom of the canister, and time of flight (TOF) values are recorded. If the content inside the canister is in a liquid state, the TOF is observed at about 54±0.5 microseconds. Due to poor weather conditions, mismanufacturing, or mishandling in transportation, if the canister’s contents have any air pockets, then the contents react and solidify. For this case, the TOF is about 40 ±0.5 microseconds only. A difference of 14 microseconds was observed when the content of the canister changed from liquid sate to solid. This allows us to determine the contents of the canister, without opening the seal.

Women’s safety has always been an issue in the modern era. They endure lot of problems like sexual harassment, physical abuse and trafficking. These are the most alarming problems in society. All these problems show a very dangerous impact on women empowerment. So, to protect women from such assaults it is very important to find a solution. In this present research work, authors designed a women safety TARA wrist band, a self-defence device for women. TASER [Thomas A. Swift’s Electric Rifle] system is used in this device. This paper deals with the materials which are used in the device, battery, mechanical, thermal and physical analysis of the device. From this analysis, operating temperatures and the load conditions are analysed to manufacture a perfect women safety wristband. Fused Deposition Modelling 3D Printing technique is used for development of the prototype.

Environmental pollution due to improper disposal of plastic waste has greatly degraded the livelihood of both humans and animals. In this article, polyethylene terephthalate (PET) bottles were used as reinforcement in scrap aluminum. The composite material was made through the stir-casting route. The samples were characterized using the microstructure, tensile strength, and hardness. Results show an increase in tensile strength up to 4% addition of PET and steady hardness reduction as reinforcement composition increases. However, the mechanical strength declines as reinforcement goes beyond 8%.
Optimal Production in Vacuum Food Packaging Thermoforming with Linear Programming
Authors: Rubio Sebastián , Vallejo-Huanga Diego
Published: October 2023

This article presents an optimization model to determine the ideal production distribution in the thermoforming lines of a sausage factory. A linear programming model subject to the simplex method is used to find the production coefficient, determining the ideal workload for three machines involved in the packaging process. The methodology considers common characteristics of the sausage industry, where production programming, thermoforming machines, and their capacities are the ones that directly influence the execution of the experiment. Using the model allows for analyzing the variations of the actual production plan and its effectiveness against the optimized production results. The experiments compared and evaluated the fulfillment of the optimization objective. The modeling was executed with the free software language programming R. A mathematical model was generated that allows evaluating and programming the optimal production in the thermoforming lines to maximize packaging and optimize resources, considering the restrictions of the process. The purpose is to avoid overproduction and misuse of available resources. The results show that the model makes it possible to optimize daily production in the thermoforming lines by 11% for October and 8% for March, equivalent to 5,500 and 3,500 units per day, respectively.

Fine and uniform carbides play a beneficial role in the high hardness and wear resistance of martensitic stainless steel. This paper investigates the effect of magnesium and rare earth(RE) on the dispersion of carbides in a high-carbon martensitic stainless steel. The results show that RE-Al-O and RE-Al-O-S inclusions were generated in RE-containing steel, while Mg-Al-O+(Ca, Mn)S and MgO+CaS inclusions were in Mg-containing steel. MC, M7C3, and M23C6 types of carbides were detected in both RE-containing and Mg-containing steels, which is consistent with thermodynamic calculation. The RE-Al-O inclusion can act as heterogeneous nuclei for carbides, while Mg-containing inclusions do not promote carbide precipitation for sulfur enrichment. The three-dimensional etching test suggests that RE-containing steel has more serious network carbides and larger carbide sizes than Mg-containing steel. The carbon segregation ratio presents an “M” shape due to δ→γ phase transformation. Rare earth is easy to combine with S and weaken the inhibiting effect of carbon segregation. Thus, magnesium has a stronger inhibitory effect on carbon segregation than rare earth.

This study aimed to assess and improve the preparedness of selected hospitals in Saudi Arabia for nuclear and radiological emergencies. A team of experts developed and issued guidelines for radiation emergency response, selected 21 referral hospitals across the country, provided technical and logistical support, evaluated preparedness and provided recommendations for improvement. An evaluation process with four essential criteria (early detection of accidents, medical response team responsibilities, availability and accessibility of equipment and supplies, and training on the implementation of the emergency plan) and 50 sub-criteria was conducted, and hospitals’ preparedness was assessed. The initial assessment showed that most hospitals had a moderate level of preparedness, with an average overall score of 67.5%. Interventions were implemented through training workshops, guidelines, checklists, and feedback. The follow-up assessment showed that the intervention was highly effective in enhancing the preparedness of all hospitals, with an average overall score of 99.1%. All hospitals achieved the benchmark of 80% or higher in all four aspects, with 14 hospitals scoring 100% and the remaining seven hospitals requiring further technical support. The study concluded that the intervention was successful in improving the preparedness of health facilities for nuclear and radiological emergencies and recommended continuous monitoring and evaluation to maintain the high level of readiness.

Published: October 2023

In this paper, a three-dimensional subspace conjugate gradient method is proposed, in which the search direction is generated by minimizing the approximation model of the objective function in a three-dimensional subspace. The approximation model is not unique and is alternative between quadratic model and conic model by the specific criterions. The strategy of initial stepsize and nonmonotone line search are adopted, and the global convergence of the presented algorithm is established under mild assumptions. In numerical experiments, we use a collection of 80 unconstrained optimization test problems to show the competitive performance of the presented method.
