Study of radioactive particle tracking using MCNP-X code and artificial neural network

Agitators or mixers are highly used in the chemical, food, pharmaceutical and cosmetic industries. During the fabrication process, the equipment may fail and compromise the appropriate stirring or mixing procedure. Besides that, it is also important to determine the right point of homogeneity of the mixture. Thus, it is very important to have a diagnosis tool for these industrial units to assure the quality of the product and to keep the market competitiveness. The radioactive particle tracking (RPT) technique is widely used in the nuclear field. In this paper, a method based on the principles of RPT is presented. Counts obtained by an array of detectors properly positioned around the unit will be correlated to predict the instantaneous positions occupied by the radioactive particle by means of an appropriate mathematical search location algorithm. Detection geometry developed employs eight NaI(Tl) scintillator detectors and a Cs-137 (662 keV) source with isotropic emission of gamma-rays. The modeling of the detection system is performed using the Monte Carlo Method, by means of the MCNP-X code. In this work, a methodology is presented to predict the position of a radioactive particle to evaluate the performance of agitators in industrial units by means of an Artificial Neural Network.

Spatio-Temporal Changing Scenario of Growth and Structure of Manufacturing Industries in Asansol-Durgapur Region, West Bengal

Asansol-Durgapur Industrial Region serves as nerve-knot of the economy of West Bengal as well as the entire economic region of Eastern India because of its enormous reservoir of excellent quality of coal of Raniganj Coalfield, outstanding network of transport by rail and road, skillful and cheap labour in close proximity of states. With the establishment of a number of large industrial units like Iron & Steel Plant, Durgapur Steel Plant, Chittaranjan Locomotive works, Durgapur Alloy Steel Plant, Durgapur Thermal Power Station, and hundreds of medium and small-scale industries have made the region great industrial belt after Hooghly industrial belt in West Bengal. Though there was rapid industrialization after independence period but the growth of industries has not taken place uniformly throughout the study area. This is because, high manufacturing intensity found in Durgapur, Asansol, Raniganj and Kulti areas whereas the Salanpur, Jamuria, Fraidpur, Barabani areas witnesses low manufacturing intensity. The decadal growth of industries also noteworthy, in 1951 there were 46 industrial units and it increased to 430 in 2019. The number of basic metal and engineering units was 2 and 18 respectively in the year 1951 whereas in 2019 the basic metal and engineering unit increased to 122 and 66 respectively. This paper primarily focuses on the estimation of spatial and temporal distribution of manufacturing industrial units, growth and structural changes, manufacturing intensity and concentration of the manufacturing sector during the period of 1951 to 2019 in Asansol-Durgapur Industrial Region.

Measuring the Physico-Chemical Impact of Wastewater from the Open Sewer in an Industrial Area: Case of the Kossodo Industrial Area in the City of Ouagadougou in Burkina Faso

Wastewater from industrial units in the Kossodo district in the city of Ouagadougou has a physicochemical impact on the environment and the population. For several years the Kossodo area was famous for the effects of wastewater from industrial units on the environment (a foul odor). We took samples from various points of the open canals in order to determine the physico-chemical parameters of this wastewater. This choice was guided by a concern to measure the physico-chemical impact of wastewater from the open sewer in the industrial zone of Kossodo in the city of Ouagadougou on the one hand and to show the danger represented by this wastewater from industrial units on the environment and public health on the other hand. The objective also guided the choice of the parameters retained for the measurement of the physicochemical impact of the industrial units wastewater of the open sewer of Kossodo zone in the city of Ouagadougou: MES, DCO, BOD5, pH, Potassium, Sodium. The results show that the wastewater from the open sewers of the industrial units of Kossodo in the city of Ouagadougou, has a high physicochemical parameter content than the authorized discharge standard.

Ecological phytomonitoring in Donbass using geoinformational analysis

The results of the phytoindication monitoring carried out in the central industrial units of Donbass during 1996 – 2021 have summarized. Botanical indication is considered as a way to carry out a reliable ecological expertise when zoning ecological crisis areas in an industrial region. Geographic information analysis of botanical and ecological indices (occurrence frequency of teratogenic deviations of plants, structure and concentration of pollen grains, level of taxonomic diversity of bryophytes) allows to visualize indicators of the state of local geosystems in an anthropogenically transformed region.

In other words, we can say that as nature of ownership changes, there is a change in monthly turnover. Likewise, the percentage share of different components of cost namely overhead cost and fixed cost of Rubber Industry in Kerala based on ownership is different and it is found more for sole proprietorship and firm respectively. The percentage share of different components of cost of Rubber Industry in Kerala based on operation is same. KEY WORDS: Monthly turnover, Cost structure, Rubber Industry, Overhead cost, Fixed cost.

INFLUENCE OF COVID-19 LOCKDOWN ON AIR QUALITY

In late 2019, a novel irresistible infection with human to human contagious transmission (COVID-19) was recognized in Wuhan, China, which has transformed into a worldwide pandemic. Nations everywhere in the world have executed a type of lockdown to hinder its contamination and moderate it. Lockdown because of COVID-19 effectively affects social and monetary fronts. In any case, this lockdown likewise has some constructive outcome on regular habitat. The study objective is to think about the adequacy of COVID-19 lockdown on the air contamination around the world. Because of pandemic, all avoidable activities around the globe were prohibited. Ongoing information delivered by NASA (National Aeronautics and Space Administration) and ESA (European Space Agency) demonstrates that the contamination level in certain nations has decreased up to 30%. The nationwide halting of public transports and closure of major industrial units has resulted in obvious significant reductions in emissions of a variety of gases related to energy and transport. The decrease of air contamination was firmly connected with movement limitations during this pandemic and five air toxins i.e., SO2, PM2.5, PM10, NO2, and CO have likewise diminished.

Frequent Crisis and Modern Trends Associated with HAZOP Study in Plants and Industrial Units

Hazard and operability (HAZOP) analysis has a well-deserved reputation for systematic and thorough evaluation of process hazards in industrial units. The method is now widely known and is in prevalent use in the chemical processing industries; so much so that in many industries performing a HAZOP has become a legal requirement for new or modified industrial units. A number of guides exist for conducting HAZOPs, the most recent being the IChemE guidelines on finest practice – second edition, published in the year 2008. In exercise however, following best practice is not that easy and many compromises have to be made in order to finish the task an added hurdle occurs when the HAZOP is led by a self-governing leader from an external company or third party as is increasingly the case. In this circumstance the person in charge also has to satisfy the customer or customer’s requirements which do not always match to the best custom. In addition there is a drift to lessen HAZOP study scope to safety health and environmental concerns only and to exclude operability and consistency issues. This has resulted from a observance mindset, possibly in an attempt to lessen liabilities. HAZOP is increasingly being seen as a conformity tool rather than as a tactic to ensure a secure, trustworthy and well designed plant. With the current financial environment we can expect these hitches to increase as project costs come under enhanced pressure and the extent of many projects is reduced. This paper discusses some of the more frequent crisis that occur during HAZOPs and some of the possible solutions in industrial units.

The Effect of Wages, Investment, Number of Industrial Units, and Number of Job Opportunities on the Level of Migration to DKI Jakarta in 2008-2019

One of the cities in Indonesia that has quite rapid economic progress is DKI Jakarta. The high minimum wage, investment, number of industrial units, and job opportunities in DKI Jakarta are factors that attract people to migrate to this city. However, in reality, the growth of in-migration to DKI Jakarta in the 2008-2019 period tends to show a decline. This study aims to determine the influence and magnitude of the effect of wages, investment, number of industries, and employment opportunities on in-migration to DKI Jakarta in 2018-2019. The analysis method used is multiple linear regression analysis and the method of least squares Ordinary Least Square (OLS). While the types and methods of research used in this research are descriptive quantitative and verification methods. The data used are data on provincial minimum wages, investment, industrial units, job opportunities, and data on incoming migration in DKI Jakarta in the 2008-2019 timeframe. The data in this study came from the Central Bureau of Statistics. The results showed that the provincial minimum wage (UMP) and investment (INV) variables partially affected the incoming oil (MM) to DKI Jakarta in 2008-2019. Meanwhile, the industrial unit variable (UIN) and the variable number of job opportunities (KKJ) partially did not affect in-migration to DKI Jakarta (MM) in 2008-2019. This research implies that in dealing with the high rate of population movement, the government needs to implement policies to overcome it such as increasing the provincial minimum wage, investment, the number of industrial units.
