Abstract

The increase in demand for petroleum as a source of energy and as a primary raw material forindustries has resulted in an increase in its production, transportation and refining, which in turn has resulted in gross pollution of the environment and soil. Due to its hydrophobic characteristics and slow process of biodegradation, petroleum can remain in the environment for a long time and its toxicity can affect negatively the impact on human, animals and aquatic ecosystems due to its carcinogenic potential. The objective of this study is to solve the chronicenvironmental contamination by oil, conventional treatment techniques and bioremediation as an alternative tool for recovery of petroleum-contaminated soils. It is widely known that the main organismsresponsible for decomposing petroleum in bioremediation are bacteria and fungi. Therefore, this paper investigates the use of Saccharomyces cerevisiae to eliminate the Total Petroleum Hydrocarbons (TPH) from soil that has been contaminated by crude oil in the lab to determine its potential to degrade petroleum hydrocarbons at 30°C for a period of 28 days under aerobic condition. The soil samples were analysed by using the EPA method from start and the end of the experimental periods using spectrophotometer. At the end of 28 days petroleum degradation was recorded. During the 28 days of incubation, the absorbance in the control is constant (0.27), when adding 1% yeast shows that there is a decrease in the absorbance to (0.15) TPH is 916.67 mg/L,; while the 2% yeast shows that the absorbance is lowered to (0.036) TPH is 750mg/L. The results showed that TPH removal from the soil utilising the Saccharomyces cerevisiaewas more successfully accomplished during the aforementioned amount of yeast added

Abstract

The transport and deposition of substances, such as soluble ions, heavy metal pollutants, bacteria, and suspension-colloidal particles(SPs), in porous media is an important yet challenging topic in environmental geotechnics. A nonlinear attachment-detachment model with adsorption hysteresisis proposed, which uses an adsorption function and scanning desorptionisotherms to model the deposition effect of SPs. The reactionrate constant related to hysteretic characteristics essentially reflects thenonequilibrium hydrodynamic process during the transport of SPs.Static deposition tests and column experiments with pulse injection areused to calibrate the transport parameters.Column penetration experiments are performed under variable injectionconcentrations and seepage velocities. The results show thatthere is good agreement between simulated and experimental breakthrough curves(BTCs).When the injection concentration is increased, the effluent concentrationclearly increases, which actually reflects a nonlinear depositionprocess. In contrast, with a decrease in the injection concentration, therelease effect of the already deposited SPs prolongs the penetrationprocess, which is also related to the hysteresis. Previously proposedlinear attachment-detachment models probably result in an overestimationof the adsorption capacity of porous media.Studies show that increasing the seepage velocity enhances thereaction rate constant between SPs and the porous medium matrix andsimultaneously strengthens the hydrodynamic force acting on SPs,which actually promotes the movement of SPs along the flowing water.For small particles, the reaction rate constant is the dominant factor.Nevertheless, for large particles, the hydrodynamic force plays an importantrole, except for the hysteretic effect caused by the collisionsbetween SPs and between SPs and the solid matrix.

Abstract

Biodiesel is an environmentally friendly fuel source with similar combustion qualities comparable to regular diesel. Microalgal biodiesel has recently attracted global attention and interest for researchers because of the fact that they are sustainable, renewable and non-toxic. In this research, using microalgae Nannochloropsis oculata, cell disruption was carried out using a high-speed homogeniser (HSH) pre-treatment technique, and lipid extraction was done using a mixture of deep eutectic solvents like methanol and hexane. Different operating input factors of HSH were examined on the microalgae to study their effective cell disruption rate and lipid efficiency. The result showed that an enhanced lipid yield of 40.56% was obtained from N.oculata, and thus, this study attempted to imply that the cell wall of the microalgae was fully ruptured, permitting the solvents to diffuse and recover lipids. The significant components of biodiesel characterisation were discovered using gas chromatography analysis, which concluded that this could be employed as a feedstock in biodiesel production.

Abstract

The nanosatellite market is rapidly growing forscientific and commercial applications. The main reason isthe availability of low-cost commercial off-the-shelfcomponents and already-developed subsystems in themarket. This evolution also enabled many universities andsmall and medium-sized enterprises (SMEs) to developtheir own satellites. The problem with small satellites is the available spaceand weight constraints for housing a large number ofrequired subsystems, such as power, attitudedetermination and control, telecommunication, andpayload. The ultimate solution is to make all subsystemssmaller and lighter. Attitude control system orientate the satellite in space to rotate solar panels towards Sun and antennas towards ground station. Normally permanentmagnets, reaction wheels, and magnetic rods are used for this purpose, but their price, weight, and size make themincompatible with small satellites. In this conference, we are going to discuss innovative embedded attitude actuators called embedded magnetorquers, which are inserted in theinternal layers of the power management PCB (printed circuit board) of small satellites. The resultant system is very light, reconfigurable andoccupies no extra space on the spacecraft.

Abstract

The purpose of the study was to delineate the epidemiological characteristics of electrocution deaths in Maryland, identify any potential risks, and address preventive measures. A retrospective review of all the deaths due to electrocution was conducted at the Office of the Chief Medical Examiner in the State of Maryland from 2005 to 2015. During the 11-year period, a total of 55 electrocution deaths were identified from the autopsy cases at the statewide medical examiner system. More males died of electrocution than females with its ratio of (M: F) = 9:1. Of the 55 cases, 67.3% were White, 18.2% were African-American, 12.7% were Hispanic, and 1.8% were other races. The age of the victims ranged from 4 to 83 years with mean age of 40 years. >96% deaths due to accidents and 3.4% were suicide. The majority of deaths (70.9%) were caused by high-voltage circuits. Approximately 64% of fatalities were work-related accidents. The study indicated that electrocution deaths frequently affected young male workers who were in contact with a high-voltage currents while on the job. The detailed death scene investigation and autopsy findings are presented. The potential hazards of electricity must continue to be addressed in public safety campaigns to prevent such deaths. Strategies should ensure safe work environments for any contact with electric currents.

Abstract

Most world problems which include industrial, biological and engineering prob-lems, present themselves in the form of non-linear partial differential equations. The characteristics of physical systems are exhibited by non-linear equations. Modelling natural physical systems using complex non-linear partial differential equations is complicated since it is difficult to obtain exact explicit solutions. Here, we look at fluid models involved in industrial processes over stretching surfaces. The phenomenon of unsteady mixed convection boundary layer flow has been considerably studied by many. The studies of these phenomena have been devoted to a lot of applications subject to different conditions.  Here, a new iteration method which converges faster will be introduced. The applica- tion of a pseudospectral method to solve coupled non-linear system of partial differential equationsmodelling boundary layer flow over a stretching surface in a rotating fluid will be demonstrated. Important flow properties such as lo-cal skin-friction coefficient, heat and mass transfer rates will also be put into consideration. Validation of the method will be conducted using convergence graphs.

Abstract

The study of longitudinal surface roughness on performance of magnetic fluid based hydrodynamic circular foot step bearing considering the slip velocity. The velocity slip is modelled by the method of Beavers and Joseph. The stochastic model is used for surface roughness. The equation for radial flow rate is solved to obtain the expression for pressure. Which is then used for calculation of load carrying capacity. It is discovered that non-dimensional slip velocity, inner radius, variance and skewness are responsible for significant decrease in the load carrying capacity of the bearing. However in the case of non-dimensional standard deviation, the load carrying capacity is increased

Abstract

Complex dynamic behavior of nonlinear structures makes it challenging for uncertainty analysis through Monte Carlo simulations (MCS). Surrogate modeling presents an efficient and accurate computational alternative for a large number of MCS. Previous researches have demonstrated that the multi-input multi-output nonlinear autoregressive with exogenous input (MIMO-NARX) model provides good discrete-time representations of deterministic nonlinear multi-degree-of-freedom (MDOF) structural dynamic systems. To investigate the influence of uncertainty propagation on system performance, the MIMO-NARX strategy is integrated with different meta-modeling techniques. Different meta-models including Kriging, polynomial chaos expansion (PCE), and arbitrary polynomial chaos (APC) are used to surrogate the NARX coefficients for system uncertainties. A nine-DOF structure is used as an MDOF dynamic system to evaluate different meta-models for the MIMO-NARX. Good fitness of statistical responses is observed between the MCS results of the original system and all surrogated MIMO-NARX predictions. It is demonstrated that the APC-NARX model with the advantage of being data-driven is the most efficient and accurate tool for uncertainty quantification of nonlinear structural dynamics.

Abstract

It has taken the globe less than four decades to transform plastic from “marvel to menace,” as mentioned by National Geographic. Plastics are a broad category of synthetic or semi-synthetic materials that contain polymers as a primary component. The majority of modern plastics are made from chemicals sourced from fossil fuels such as natural gas or petroleum. Now that the ban on single-use plastic is the new normal, the direct impact of the ban will definitely reduces plastic waste, but it may also result in the loss of capital and important resources of Ice-cream industries, and it is at this point that we must consider the overall impact. Between 1950 and 2017, 9.2 billion tons of plastic are thought to have been produced. Since 2004, more than half of this plastic has been produced. 400 million tons of plastic were created in 2020. By 2050, it is predicted that yearly worldwide plastic production will exceed 1,100 million tons if current trends in plastic demand hold. So far, 14% of all plastic waste has been burned, with less than 10% recycled. These waste products frequently run into sewage systems, plugging the mouths of drain holes and causing a spill of murky water over the surface of the ground. Looking for alternative solution Ice-cream vending machine seems a good fit, is economical and preferred by people (as our snowball sampling study says) as this study checks and deals with the overall impact of using vending machines for ice creams, its impact on industry and most importantly consumer  welfare. Our sample data only gives inferences of population of tier 1 & tier 2 demographics and might not hold for tier 3 demographics. Moreover the market research gives a lot of positive insights about this industry.
