    Electromagnetic waves are the analytical solutions of Maxwell's equations that represent one of the most elegant and concise ways to state the fundamentals of electricity and magnetism. From them one can develop most of the working relationships in the electric and magnetic fields. Considering deeply the effect of charge variation in Maxwell’s equations for time varying electric and magnetic fields of charges in moving inertial frame, the magnitude of charge particles vary according to Asif’s equation of charge variation. Consequently the Maxwell’s equations give different results to an observer measuring at rest. This research paper explained the effect of charge variation in Classical Electromagnetic theory, Maxwell’s equations, Coulumb’s law, Lorentz force law when we are referring to any inertial frame.DOI:http://dx.doi.org/10.11591/ijece.v4i2.535

    Telehealthcare systems are nowadays becoming a massive daily helping kit for elderly and disabled people. By using the Kinect sensors, remote monitoring has become easy. Also, the sensors' data are useful for the further improvement of the device. In this paper, we have discussed our newly developed “Eldo-care” system. This system is designed for the assessment and management of diverse neurological illnesses. The telemedical system is developed to monitor the psycho-neurological condition. People with disabilities and the elderly frequently experience access issues to essential services. Researchers today are concentrating on rehabilitative technologies based on human-computer interfaces that are closer to social-emotional intelligence. The goal of the study is to help old and disabled persons with cognitive rehabilitation using machine learning techniques. Human brain activity is observed using electroencephalograms, while user movement is tracked using Kinect sensors. Chebyshev filter is used for feature extraction and noise reduction. Utilizing the autoencoder technique, categorization is carried out by a Convolutional neural network with an accuracy of 95% and higher based on transfer learning. A better quality of life for older and disabled persons will be attained through the application of the suggested system in real time. The proposed device is attached to the subject under monitoring

    Increase urbanization of the world leads to increase in fuel demand. Crude oil based fuel such as diesel fuel; petrol and natural gas are the main fuels. Moreover natural resource reservoirs are in specific regions of the world. Many countries of the world along with Pakistan are facing shortage of the petroleum products. Therefore alternative energy resource must be explored in order to cope with the fuel demand.  In this research work, a 60 hours endurance test has been carried out on horizontal type single cylinder diesel engine. During endurance test, three fuel   samples such as D100 (%diesel as a baseline), B25 (waste cooking oil biodiesel 25% and 75% diesel fuel) and B25+LPG (liquefied petroleum gas and waste cooking oil biodiesel) respectively have been taken to determine the engine performance and noise emission level. Engine performance and noise emission level were taken at constant rpm of 1300 with variable loads from 0.0(no load) to 1.6kg-m at an interval of 0.2kg-m. however analysis of results show that the brake specific fuel Consumption (BSFC) of B25+LPG decrease with increasing the brake power and the brake thermal efficiency increase as increasing the brake power. However, engine noise emission level from three directions such as front back and left show lower noise emission in case of biodiesel and LPG blended as compared to diesel fuel

    In the present study, attempt was made to explore the economic implication of tomato in Nausharo Feroze Sindh. For this purpose 60 growers were selected from different villages of District Naushero feroz of Sindh province during the year 2013 using survey method of study.  The data on various costs, physical and revenue productivity were collected from 60 randomly selected tomato farmers. Result revealed that the education level of selected growers was in order of 25.00% primary (5years), 36.66% of middle (8years), 16.66% matriculate (10years) 3.33% educated from college and university, 1.70% graduate the 18.33% of tomato respondents were illiterate. Results further indicate that farmers incurred an average per hectare fixed costs. Rs 33187.00 include Rs 700.00 for land tax, Rs 32487.00 for rent of land. The results revealed that tomato farmers incurred an average per hectare cost of Rs 19780.75 as labor cost. An average per acre marketing cost of 30457.65 on tomato capital input used, and an average per acre marketing cost was Rs. 4191.73 On an average per acre spent a total cost of production of Rs. 87617.13. An average per acre Physical productivity was 186.00 in mounds. An average per acre Revenue productivity was Rs.158750.00 and the Net income was 71133.00 an availed input output ratio 1:1.81 it means that with the investment of Rs.1.00 in tomato enterprises they yielded Rs.1.81. The cost benefit ratio of the cultivation of tomato at 1:0.81 it means that the tomato growers fetched Rs.0.81 on each rupee investment of tomato. The poor production implies that the soil quality, inadequate canal water, insect pest and poor extension services could be the causes this low production. The empirical result indicates that significant increase in input of tomato in the study area could be traced mainly to use of latest technology. Keywords: Tomato, cost, fruit yield, labor, net returns, and cost-benefit ratio

    Effects of hospital facilities on patient outcomes after cancer surgery: an international, prospective, observational study

    Get PDF
    Background Early death after cancer surgery is higher in low-income and middle-income countries (LMICs) compared with in high-income countries, yet the impact of facility characteristics on early postoperative outcomes is unknown. The aim of this study was to examine the association between hospital infrastructure, resource availability, and processes on early outcomes after cancer surgery worldwide.Methods A multimethods analysis was performed as part of the GlobalSurg 3 study-a multicentre, international, prospective cohort study of patients who had surgery for breast, colorectal, or gastric cancer. The primary outcomes were 30-day mortality and 30-day major complication rates. Potentially beneficial hospital facilities were identified by variable selection to select those associated with 30-day mortality. Adjusted outcomes were determined using generalised estimating equations to account for patient characteristics and country-income group, with population stratification by hospital.Findings Between April 1, 2018, and April 23, 2019, facility-level data were collected for 9685 patients across 238 hospitals in 66 countries (91 hospitals in 20 high-income countries; 57 hospitals in 19 upper-middle-income countries; and 90 hospitals in 27 low-income to lower-middle-income countries). The availability of five hospital facilities was inversely associated with mortality: ultrasound, CT scanner, critical care unit, opioid analgesia, and oncologist. After adjustment for case-mix and country income group, hospitals with three or fewer of these facilities (62 hospitals, 1294 patients) had higher mortality compared with those with four or five (adjusted odds ratio [OR] 3.85 [95% CI 2.58-5.75]; p<0.0001), with excess mortality predominantly explained by a limited capacity to rescue following the development of major complications (63.0% vs 82.7%; OR 0.35 [0.23-0.53]; p<0.0001). Across LMICs, improvements in hospital facilities would prevent one to three deaths for every 100 patients undergoing surgery for cancer.Interpretation Hospitals with higher levels of infrastructure and resources have better outcomes after cancer surgery, independent of country income. Without urgent strengthening of hospital infrastructure and resources, the reductions in cancer-associated mortality associated with improved access will not be realised

    The majority of social network (SN) users are using calling service in SN to build communication across the countries, so the live communication between users requires too much network resource to decrease roughness in audio and video calls. So to improve the quality of service SN provider needs user experience so to assess the quality of experience (QoE) of calling service in SN we selected three popular SNs Facebook, hangout, and Wechat. We used a questionnaire to collect QoE of calling service in SN using the mobile network (MN) and broadband Network (BN). Results show users were satisfied from audio call service of Wechat on BN service and user satisfaction level was excellent of video quality for Wechat video calls using BN and ratings for voice quality in video call were good in the hangout on BN and MN internet
