Chemical, Mineralogical and Metallurgical Characterization of Goethite Rich Iron Ore Sinter

In this paper, the influence of structural water present in goethite rich ore fines on sinter properties like mean size, RI, RDI, TI, AI, and microstructure was studied. For this three plant sinters with different basicities (A1, A2, and A3) were experimentally produced varying the raw mix. From the study on variable basicity, it is found that increased basicity has good effects on the sinter properties. The desired norms of metallurgical properties for good quality sinter required for large size blast furnace met with increased tumbler index and decreased abrasion index. The RI is also better in highly fluxed sinter A3 and the RDI is low. All these are happening due to the availability of more free time and porosity. The mean-size of sinter also increases with the increase of basicity. The reducibility index and RDI of sinter A2 and A3 appear to be similar although there is a variation in chemistry and basicity, this may be attributed to use of more micro-fines in the raw material of sinter A3. The specific consumption of coke rate is highest for sinter A3 is also due to more micro-fines in raw materials. From the microstructure, it is found that in sinter A1 more magnetite and fewer ferrites are developed in comparison to A2 and A3. The silicoferrites of calcium and aluminium (SFCA) developed in sinter A2 and A3 are acicular in the structure which provides better strength to the sinter. Also, the porosity is more in case of A2 and A3 which can accelerate the reducibility process.

Anxiety Perceived By Children during Venipuncture

Abstract: Introduction: When it comes to pediatric patients undergoing venipuncture, it should be every phlebotomist’s nurse’s top goal to reduce a child’s fear, pain, and distress. Most children have some fear of needles. When a child’s level of distress in anticipation of the venipuncture is on the rise, it can be a rather difficult task for the nurse and parent to make the blood collection process go over smoothly! Methods: This study was conducted using a descriptive correlational design among 181 children who met the inclusion criteria using purposive sampling technique. Data collection was done using Demographic, Clinical Variables Proforma and Modified Venham’s Anxiety Scale. Results: The findings revealed that 42.5% of the children had moderate anxiety, 7.7% had worst anxiety and 1.10% had no anxiety during venipuncture. The study findings revealed significant association between the anxiety and age of the child at the level of (P < 0.05)

Performance of Banking Sector Selected Companies Based on Macro and Micro Economic Variables

This project is an effort to study the performance of BANKING sector companies listed in our title based on the movement of equity share prices in cash markets which are an indication of the manner in which the information is received, processed, assessed and reflected by the investing community in the country. Concepts like efficiency market hypothesis which base themselves on the way in which the information about companies is internalized by the capital markets are utilized for our study. As this is an experiential study two methods of action are implemented. A generalized risk diversified portfolio purchases and sales are made as well as a sector-specific intensive portfolio trades are also made for a period of 45 days. An investment methodology which incorporates both the macro and microeconomic variables is formulated and utilized for the purpose of selection of scripts based on various informational inputs. The results of the portfolio are analyzed both on a daily basis and a periodic basis using the following tools, viz: Treynor ratio, Sharpe ratio, and Jensen’s alpha, which are accepted as valid barometers of the performance of a fund manager. The undersigned would be the fund manager for the limited purpose of this project and the finally the alpha would indicate the success or failure of the experiment on which this report is based.

Air Pollution Trends in India Past 10 Years

The major problem in INDIA is the decrease in air quality and this trend has been in increasing drift from the past years in the major cities of INDIA. The significant reasons for this are a rapid increase in population and acreage, from which there is a substantial demand for personnel and public transport which keeps the environment of a certain city in crux. The air pollutants in the major cities of INDIA exceed the NATIONAL AMBIENT AIR QUALITY STANDARDS (NAAQS). (Guttikunda, Goel et al. 2014). The pollutants include gaseous contaminant which might be noxious gaseous pollutants and organic gaseous pollutants such as hydrocarbons and particulate matter which might be in the form of suspended particulate matter or Respirable suspended particulate matter (particle size less than 10 micrometers. Hence, it is also called particulate matter 10).(Organization 2003)

Design and Implementation of Smart Home Control Systems Based on Wireless Sensor Networks and Power Line Communications

In this system, they are implementing a smart home control network by using wireless sensor networks(WSNs)  power line communication(PLCs). In the smart home, the goals are to reduce the impact of wireless interference. In the smart home, they are to control the network 4 unnecessary energy consumption. In each room, they are establishing an isolated WSNs with one coordinator with the integrated into the PLCs transceiver. Management station via PLCs in WSNs obtained by transferring environment parameters for is coordinator responsible. In smart home appliances, they control the message for PLCs then it's directly transferred by using rather than WSNs proposed smart home control network is substantially mitigated. The impact of wireless interference on the experimental results. Lightning system & analysis of the illumination of a fluorescent lamp are presented additionally in smart home control. Control was evaluated without the energy saving of lighting system. Under the smart control, it can be reduced at 40% least on the cloudy or sunny day & it can indicate the numerical result of electricity consumption. The moreover smart home control network algorithm implemented by the proposed for the prototype. Experimental results presented in this system show the capacity of these modems to overcome the hostile environment due to the inverter and to guarantee reliable communication over the PWM network. The proposed system is practically possible for smart home control networks.

A Research on Fault Detection and Diagnosis of Rolling Bearing

Mechanical failure prevention and condition monitoring have been one of the mechanical engineers’ concerns in recent years due to the personal safety, reliability, failure cost, and equipment downtime issues. Proper system failure prevention process helps to reduce the possibility of the system malfunction, identification of source causes, and troubleshooting. The use of novel sensors such as an Air-coupled ultrasonic transducer, Eddy current, Piezoelectric ultrasonic transducer as diagnostic tools for detection of bearing faults has been investigated. A series of experiments were carried out in a laboratory environment. Localized defects with different sizes were created intentionally on the test bearing components simulating evolving cracks or other related faults. Four different signal processing techniques were applied to extract the signal features. The resulting data for different bearing speed and load showed that the sensors are capable of detecting different types of defects located on the bearing components.
