Modelling and availability analysis of container manufacturing industry with Petri Nets

The present work deals with the modeling and availability analysis of Container Manufacturing industry by applying Petri Net (PN) technique and attains the various availability levels by varying various operating parameters that affects the overall availability of the system. This system consist of four subsystems/components namely Gas Cutting machine, Hydraulic Press, Rolling machine and Submerged arc welding (SAW) welding machine. For the mathematical recreation of the system pertaining to the real environment, a Petri module of GRIF 2021 software was used. The model of the system has been made with Generalized Stochastic Petri Net (GSPN) considering exponential distribution for the failure of the components. In the existing research, an attempt has been made to identify the most critical component of system and suggest the repair priorities of different components on the basis of effect of repair rate on overall system availability. Also an attempt has been to find out the optimum number of repairmen. In the present work Hydraulic Press is the critical subsystem having more effect on availability of the system as compared to other subsystems. The optimum no of repairmen required are four thereafter, no increase in system availability seen in the present case. The results of present research work are might be helpful for plant management to design a suitable maintenance strategy to meet one of the objectives i.e. economically maintenance with maximum availability of the system.

Growth response of pigeon pea (Cajanus cajan L. Millsp) on saline and alfisol soils

As an archipelago country, Indonesia is surrounded by abundant saline soils which could be potential for growing food crops. The research work was conducted to study the growth responses of some pigeon pea genotypes on saline soils. The genotypes of Pigeon pea (LG Kidul, Mega, 90024, 91043 and 94028), as treatment, were grown on Alfisol soil (non-saline) and on saline soil. The experiment was carried out using completely randomized design and replicated three times. All data observed were analyzed by employing standard deviation from 3 replicates. The results of present research work revealed a significant growth retardation of pigeon pea when grown on saline soil. All growth parameters, plant height, plant diameter, root dry weight, and shoot dry weight were significantly lower on saline soil than on Alfisol soil. High concentration of Na+ was observed in roots, shoots and leaves of pigeon pea indicating growth retardation and toxicity symptoms of pigeon pea on saline soil was due to Na+.

The Relationship Between Height Components and Bi-iliac/Bi-acromial Index with Blood Pressure Among Chakma Tribal Children of Tripura Aged 6-16 Years

Blood pressure in pre-pubertal and pubertal age group is now an alarming situation to health professionals worldwide. Little knowledge is still with us about how different body composition parameters correlate with blood pressure. Blood pressure (BP) correlates with various factors like weight, height, sitting height (SH) among children and adolescents in developed countries with upper-middle socio-economic society. Intention of present research work is to contrast sitting height, relative sitting height ratio (Cormic Index), biiliocristal to biacromial ratio and BMI of rural Chakma boys and girls between the age 6-16 years of Tripura, North-eastern State, with the National Health and Nutrition Examination Survey III (NHANESIII) reference data to conclude the correlation among sitting height, relative sitting height ratio, biiliocristal-biacromial ratio and BMI with BP among Chakma children of lower socio-economic group of Tripura. A total of 1350 children (676 boys and 674 girls) of 12 government schools from Chakma community aged 6-16 years were selected by stratified cluster random sampling method of North and Dhalai district of Tripura, undergo blood pressure and anthropometric measurements using standard techniques. Multiple regression is applied for establishing the relationship between height, sitting height, relative sitting height ratio, biiliocristal-biacromial ratio and BMI with Systolic blood pressure (SBP) and Diastolic blood presure (DBP) among these children. In comparison with NHANES III reference data, Chakma children aged 6 to 16 years showed lower mean sitting height value. In the multiple regression analysis, sitting height is positively associated with systolic BP (β=0.893; 95% Ci=0.964-0.966) and diastolic BP (β=0.505; 95% Ci=0.935-0.938) in both the sexes. The results of present research work is statistically significant for both sitting height and cormic index with systolic BP (β=0.650; 95% Ci=0.963-0.970 and β=0.103; 95% Ci=0.963-0.970 respectively), whereas only sitting height remains significant with diastolic BP (β=3.519; 95% Ci=0.934-0.946) after being adjusted for age, gender and BMI among Chakma children. The present findings recommended a must large population based research work after being adjusted for factors like dietary habits, athletic performance, salt intake, socio-economic status etc. for accurate estimation of predominance of hypertension among North-eastern children and adolescents. Significant positive association was found between systolic and diastolic blood pressure together with the height, sitting height, relative sitting height ratio among studied population.

Prevalence and distribution of human malarial infection in district Multan, Punjab, Pakistan

Abstract The present study was undertaken during 2015-17 with the objective to provide data of malarial infections in human population based on incidences in twenty different localities of district Multan, Punjab, Pakistan. The blood slides of suspected patients were studied to identify the malarial parasites. Slide positivity was found to be 1478 (39.20%) out of 3770 and Plasmodium vivax infection was 905 (61.23%), Plasmodium falciparum 425 (28.75%) and mixed species (P. vivax and P. falciparum) 148 (10.01%) were identified. In the month of December, 150 cases (73.25%) of P. vivax infection counted to be the highest, whereas, 42 cases (58.33%) of P. vivax in the month of September were recorded. The P. falciparum infection remained highest in the month of August with 58 cases (25.66%) and lowest in the month of May with 24 (23.76%). Similarly infection of mixed species remained highest 30 (13.27%) in August and lowest 7 (7.60%) in the month of February. Infection in male was highest 850 (57.51%) and female was lowest 628 (42.48%). No incidence of Plasmodium ovale and Plasmodium malariae infection was to be observed in this study. The results of present research work concluded that P. vivax and P. falciparum are serious health hazards which can ultimately lead to serious cerebral malaria problems. However, no association was found between age group, sex and type of infection. Therefore, it can be concluded that the incidence of any type of infection may happened from person to person of any age group and in any sex.

Effect of Education and Socioeconomic Status on Anxiety, Depression and Stress Level of Cancer Patients

The prevalence of psychological distress among cancer patients is high, and they are at higher risk of developing severe anxiety, depression and potential mood disorders. The present research examined educational level and socioeconomic status differences in the degree of anxiety, depression and stress among cancer patients. The sample consisted of 540 patients within the age range of 25-45 years. The sample for the study was obtained from the various Hospitals of Ahmedabad city. The purposive sampling technique was used because the patients were selected on the basis of the inclusion-exclusion criteria such as 1) age range within 25-45 years; 2) willingness to participate in the present research; 3) suffering from lungs and breast cancer in the first stage; and 4) being treated in outdoor settings of public hospitals of Ahmedabad city. Results of present research work demonstrate that there is an influence of education level and socioeconomic status of cancer patients on anxiety, stress and depression level of cancer patients. The government should focus on characteristics of lower-income occupation and lower educational attainment group to develop more accurate and effective prevention and treatment strategies for cancer.

Analysis of Radiative Magneto-Nanofluid over an Accelerated Plate in a Rotating Medium with Hall Effects

Present research work has been undertaken to analyze the effects of Hall current on natural convective flow of radiative, incompressible, viscous and electrically conducting magneto-nanofluid over a uniformly accelerated moving vertical ramped temperature plate in a rotating medium. Three types of water based nanofluids containing the nanoparticles of alumina, copper and titanium oxide have been accounted. The mathematical model of the problem has been presented using the nanoparticle volume fraction model. The Laplace transform technique has been employed to solve the mathematical model. The closed-form expressions of nanofluid velocity, temperature, shear stress and rate of heat transfer at the plate have been obtained for both the conditions of ramped temperature and isothermal plates. The effects of various physical parameters on the nanofluid velocity due to primary and secondary flows and temperature have been exemplified using various graphs whereas, the numerical values of shear stress and rate of heat transfer at the plate have been reported in tabular form for different values of physical parameters of interest. Moreover, the numerical results have been compared for the natural convective flow near ramped temperature plate with the corresponding flow near isothermal plate. It has been noted that both the nanofluid velocity and temperature are higher in magnitude in the case of isothermal plate than that of ramped temperature plate. The results of present research work have been validated with the earlier published work.
