Modeling of Explosive Processes in Anisotropic Media where Boundary of the Influence Region is Identified

Nowadays, explosive processes are widely used for the optimization of extraction minerals processes, in the buildings construction and industry. This practice allows to significantly increase the speed of the work and, at the same time, reduce it cost. However, side effects of the explosion usage can be catastrophic, since its destructive power is capable of completely demolishing even fairly stable buildings and causing irreparable damage to the environment, therefore there is a need for a precise mathematical modeling of the explosive process with a detailed calculation of all its consequences.One of the models used to investigate the explosion process is a fluid based on the simulation of an environment in which an explosion occurs as a filtration fluid. In this case, the velocity field generated by the explosion is usually considered to be potential.This article deals with a mathematical model of the explosion process based on a liquid model. It takes into account the mutual influence of the deformable anisotropic porous medium parameters and the explosive process characteristics. The corresponding boundary value problem is solved using the numerical quasiconformal mappings method which ensures the possibility of its solution taking into account the presence of the reverse effect, the existence of which essentially complicates the process of solving the problem by other, less «dynamical» methods. Algorithm used in the modelling of similar processes in hydrodynamics and electrodynamics, in particular for the study of filtration processes and electromotography is adapted for solving appropriate boundary value problems. The method of identifying the external boundary of the domain of the explosive process influence is developed by introducing certain changes to the «classical» algorithm for solving such a type of boundary problems for the twice-bounded domain since the last one requires a priori assignment of the inner and outer domain contours

The Use Of Agricultural Waste In Solving Of Environmental Problems In Democratic Republic Of The Congo

The presence of chromium in wastewaters produced from mining industries in Democratic Republic of the Congo is harmful for the environment. As a promising and polishing method for heavy metals removal from wastewaters, adsorption has been used with agricultural waste as low adsorbent. In this study, the use of sugar beet pulp has been investigated for the removal of hexavalent chromium from aqueous in batch adsorption mode. Adsorption experiments were conducted to obtain the optimal conditions combinations for the highest percent removal. Four parameters were studied such as contact time (30–180min), initial chromium concentration (10-50mg/L), pH (2-9) and solid to liquid ratio (0.25 g/100 mL-3 g/100 mL). However, the agitation rate was equal to 100 rpm and the room temperature was considered. The highest percent removals of 90.53% for 10 ppm concentration and 76.34% for 50 ppm concentration were achieved at the following conditions: pH 2, contact time 90 min, S/L ratios of 2 g/100 mL and 3 g/100 mL respectively. Langmuir and Freundlich adsorption isotherms were used for the mathematical description of adsorption equilibrium. Freundlich isotherm fitted well the equilibrium data. The maximum capacity (Qmax) from the Langmuir isotherm was found to be 11.299 mg/g. These results indicated that sugar beet pulp can be used as low cost adsorbent for the removal of chromium from mining industries wastewater to avoid environmental problem

Integrated management tool for water, crop, soil and N-fertilizers: the Saltmed model

Good management will be required to double food production by 2050. Testing management strategies is commonly carried out in the field. Such trials are costly and require quite a long time to produce consistent and reliable results. An alternative option to field trials would be the use of tested models. Models can run with ‘what-if’ scenarios depicting different types of field management. They are a less costly and faster alternative to field trials. In contrast to some existing models, the SALTMED 2013 model is designed for general applications that include various irrigation systems and water application strategies, water of different qualities, variety of crops and trees, different nitrogen based fertilizers and different soil types. The model can simulate up to 20 fields with different treatments, different crops, different irrigation systems and management as well as different N-fertilizer applications. The SALTMED model has been tested using field experiment data from Portugal, Italy, Denmark, Morocco, Egypt, Syria, Brazil and Iran. It successfully simulated soil moisture, salinity, nitrogen content, grain yield and total dry matter. The model provides academics, professionals and extension services with a management tool for crops, soil, water and nitrogen fertilizers. This paper describes the processes, the equations of the model and summarizes the different applications and results obtained

The effect of auditory stimulation on pain response of preterm infants

This study aimed to evaluate the effect of auditory stimulation on preterm infants' pain responses. A quasi-experimental design was utilized in this study. Thirty preterm infants were recruited for the study. They were one group used for three days as day one (routine care), day two (music intervention) and day three (recorded mother voice intervention) before, during and after blood sample procedure (heel prick) from Cairo University hospitals (El Monira and Kasar Aini). A tool containing two parts was used for data collection: 1) socio-demographic data for the preterm infants and the mothers, 2) Premature Infant Pain Profile (PIPP) tool for physiological responses (heart rate, oxygen saturation) behavioral state, brow bulge, eye squeeze, nasolabial furrow and respiratory rate was determined. Results of the study showed that during heel prick the majority of preterm infants (96.7%) who were exposed to recorded mother voice had highly statistical significant no or minimal pain followed by music groups (66.7%). On the other hand, nearly half of the cases (46.7%) had moderate pain and (30%) had severe pain among control group. There were significant differences between the three groups in the behavioral state, brow bulge, eye squeeze and nasolabial furrow (P≤0.001) and improved oxygen saturation (P≤0.05). After heel prick, the preterm infants (100%) who were exposed to recorded mother voice had highly statistically significant no or minimal pain in the items of behavioral state, eye squeeze and nasolabial furrow (P≤0.001), brow bulge was significantly lower (P≤0.05) when comparing by control or music group. In Conclusion, exposure to recorded mother voice during heel prick of preterm infants is better than exposure to music or no intervention and this was manifested by lower pain level, decrease heart rate, improved oxygen saturation and respiration. Key words: Auditory stimulation; recorded mother voice; music; pain response; physiological responses; behavioral stat

The effect of saline irrigation water on the yield of pepper: experimental and modelling study

The present study investigates the impact of using saline water on pepper crop yield and the application of a numerical model in predicting soil moisture and relative yield under saline irrigation conditions. In the greenhouse experimental study conducted in Antalya, Turkey, the effects of different irrigation regimes with salinity treatments using a drip irrigation system were investigated for two pepper varieties. The irrigation regimes consisted of four irrigation treatments with four salinity levels in two cropping seasons—spring 2011 and autumn 2011. The numerical model SALTMED was used and calibrated using measured soil moisture of a control experiment run during spring 2011. After the calibration, the model was validated using other experimental treatments during spring 2011 and all the experimental treatments in autumn 2011, with appropriate salinity stress parameter π50 values which are calibrated versus the highest salinity treatments in the spring 2011 and autumn 2011 experiments. The predicted results show the ability of the model to reproduce the measured soil moisture at three soil layers 0–20, 20–40 and 40–60 cm. The predicted relative yield results are in good agreement with measured data. Although the numerical model SALTMED has been used in several studies in the past, this is the first study that illustrates the potential capacity of the model for use in managing greenhouse production
