Public Health Impact of Particulate Matter Pollution in Nepal: A Review | IJSTE JOURNAL VOL 3, ISS 4

Public Health Impact of Particulate Matter Pollution in Nepal: A Review

Worldwide air pollution continues to pose a significant threat to human health. Air pollution is a major environmental risk to health. According to Yale Environmental Performance Index (EPI) 2016, Nepal ranked on 149 among 180 countries in terms of air quality. Nepal’s capital city Kathmandu, which also chokes beneath a blanket of pollution, there is neither data nor any proper information available regarding air quality. Different natural and anthropogenic reasons are responsible for the emission of complex mixtures of air pollutants, many of which are harmful to health. Particulate matter also consists of a complex mixture of solid and liquid particles of organic and inorganic substances suspended in the air. Particulate matter affects more people than any other pollutant. There is a close, quantitative relationship between exposure to high concentrations of small particulates (PM10 and PM2.5) and increased mortality or morbidity, both daily and over time. The effects of particulate matter on health occurs at levels of exposure currently being experienced by many people both in urban and rural areas and in developed and developing countries. Fine particles are more dangerous than coarse particles, as PM2.5 can penetrate into the alveolar regions of the lungs these particles may cause serious damage to developing lungs of children. Ambient particulate matter is responsible for harmful effects on health, even in the absence of other air pollutants. Long-term exposure to current ambient particulate matter concentrations may affect the lungs of both children and adults and may reduce life expectancy by a few months, mainly in subjects with pre-existing heart and lung diseases. Acute exposure studies that evaluated short-term (usually daily) variations in health end points such as hospitalizations, and lung function associated with short-term variations in levels of pollution. Long term (months, years) exposure can cause some chronic health issues like includes, increased mortality rates, reduced survival times, chronic cardiopulmonary disease and reduced lung function. The issues of particulate matter pollution should be addressed by the national level policy that can be applied at different public and private sectors. The government of Nepal has introduced several policies, legislation and standards related to air pollution. Those policies and legislation need to be implemented to fight against the pollution.

Effect on Concrete Strength Due to Addition of Fiber | IJSTE JOURNAL VOL. 3, ISS 1

Effect on Concrete Strength Due to Addition of Fiber

Concrete is most widely used construction material in the world. Fiber reinforced concrete (FRC) is a concrete in which small and discontinuous fibers are dispersed uniformly. The fibers used in FRC may be of different materials like steel, G.I., carbon, glass, asbestos, polypropylene, jute etc. The addition of these fibers into concrete mass can dramatically increase the compressive strength, tensile strength, flexural strength and impact strength of concrete. FRC has found many applications in civil engineering field. Based on the laboratory experiment on fiber reinforced concrete (FRC), cube and cylinders specimens have been designed with steel fiber reinforced concrete (SFRC) containing fibers of 0% and 0.5% volume fraction of hook end Steel fibers of 53.85, 50 aspect ratio. Comparing the result of FRC with plain M20 grade concrete, this paper validated the positive effect of different fibers with percentage increase in compression and splitting improvement of specimen at 7 and 28 days, analyzed the sensitivity of addition of fibers to concrete with different strength.

Modification in Weld Overlay for Productivity and Corrosion Resistance | IJSTE JOURNAL VOL 2, ISS 2

Modification in Weld Overlay for Productivity and Corrosion Resistance

This paper focuses on the modification in overlay welding in the industries. Industries have increased the possibility of severe corrosion and wear in process pressure vessels. The industries must upgrade the corrosion and wear performance of these main important parts. It is essential to surface non-alloyed or low alloy base materials with high-alloy cladding. The Electro slag strip cladding (ESSC) or Electro slag welding (ESW), Gas metal arc welding (GMAW) processes are appropriate for applying welded deposits over large surface areas. The paper indicates how the modification helped in order to improve the production rate as well as corrosion resistance properties, hence improvement in the quality of the weld overlay. How production is increased with the use of Electro slag strip cladding instead of Gas metal arc welding is discussed in this paper. Material used for Electro slag strip welding is also discussed.

Faults in Transformer Winding and Probing their Occurence by S-Transform and RBF Neural Network Technique | IJSTE JOURNAL VOL 2, ISS 9

Faults in Transformer Winding and Probing their Occurence by S-Transform and RBF Neural Network Technique

Now a days significant enhancement of certainty, reliability and economics of the power transformer is an important topic in power system engineering because among all equipment as for expedition used in electrical systems power transformer is one of the most costly piece of equipment. So that accurate diagnosis of fault has been always been a major issue. Simulation studies based on transient model of transformer winding enhance understanding of surge voltage and fault current waveforms. Those are non-stationary in nature. The non -stationary nature of current waveforms inside the transformer winding requires the model parameter to be both time and frequency dependent. it will help to detect type of fault as well as location of occurrence using simulation studies. This paper aims to present a technique for diagnosis of the type of the fault and location of occurrence. . The proposed method is based on a transient model based transformer under impulse test and S-Transform with good time frequency resolution for all frequencies (multi resolution). S-Transform is used to produce a stock well coefficient vector which utilized as inputs testing set to a Radial Basis Function Neural Network (RBF). The fault conditions are simulated by the variation of fault location according to inter turn winding of power transformer or disc. The training is conducted by programming in MATLAB. The robustness of the proposed scheme is investigated by synthetically polluting the simulated voltage signals with White Gaussian Noise. The suggested method has produced fast and accurate results. Estimation of fault location is intended to be conducted in future.

Experimental investigation on effect of EGR on biofuel fueled HCCI engine using external fuel vaporizer- A Technical review

The Homogeneous charge compression ignition (HCCI) combustion is an alternative to current engine combustion systems. The research in HCCI is being carried out to use it as a method to reduce emissions and also enhance engine efficiency. HCCI has the potential to nearly eliminate NOx emissions while increasing efficiency as in diesel engine. HCCI adapts a pre mixture of gas-phase fuel and air being burned spontaneously and entirely by an auto ignition process. Homogeneous Charge Compression Ignition (HCCI) engines promises a high thermal efficiency combined with low levels of nitrogen oxides and particulate matter emissions. The purpose of this study is to summarise the effect of alternative fuel when used in the HCCI engine combustion process. Modification of single cylinder diesel engine runs on HCCI mode with diesel and biofuel. Installation of EGR system on HCCI engine. To study the effect of EGR rate on the engine exhaust parameter like nitrogen oxides (NOX), carbon oxides (CO and CO2), particulate matters (PM) and unburnt hydro carbons (UHC) by running the engine on HCCI mode with biofuel.

Experimental Approach for Selection of Tool Steel Using Heat Treatment Process with MTTF and MTBF | IJSTE JOURNAL VOL-2 ISS-8

Experimental Approach for Selection of Tool Steel Using Heat Treatment Process with MTTF and MTBF

Tools steels are generally used in forming process of operation under definite mechanical properties of the sheet metal. At the same time failure of tools steels take place because of many number causes or insufficient material selection criteria. Under this paper we have taken the five samples as punch materials i.e. EN-31, OHNS, D-2, EN-9 and D-3 to find out the different causes of punch failures. Main objective is to study the effect on the hardness of tool steel after heat treatment processes. Also MTBF and MTTF are reliability terms based on methods and procedures for lifecycle predictions for a product. These terms providing a numeric value based on a compilation of data to quantify a failure rate and the resulting time of expected performance. The numeric value can be expressed using any measure of time, but hours is the most common unit in practice. Fracture surface displays typical ductile fracture, and the outer and inner surface of the part punched off is full of little bowings around which there are many micro cracks caused by the stretch stress under biaxial strain/stress state. This survey also helps to find out the failure mode appraisal in inner lower control arm and punch with their preventive methods.

#IJSTE JOURNAL : Recyclable Thermoset Plastics (NEW TECHNOLOGY)

IJSTE :  International Journal of Science Technology and Engineering

TITLE: Recyclable Thermoset Plastics

Plastics are divided into thermoplastics and thermoset plastics. The former can be heated and shaped many times, and are ubiquitous in the modern world, comprising everything from children’s toys to lavatory seats. Because they can be melted down and reshaped, thermoplastics are generally recyclable. Thermoset plastics however can only be heated and shaped once, after which molecular changes mean that they are “cured”, retaining their shape and strength even when subject to intense heat and pressure.

       Due to this durability, thermoset plastics are a vital part of our modern world, and are used in everything from mobile phones and circuit boards to the aerospace industry. But the same characteristics that have made them essential in modern manufacturing also make them impossible to recycle. As a result, most thermoset polymers end up as landfill. Given the ultimate objective of sustainability, there has long been a pressing need for recyclability in thermoset plastics.

      In 2014 critical advances were made in this area, with the publication of a landmark paper in the journal Science announcing the discovery of new classes of thermosetting polymers that are recyclable. Called poly(hexahydrotriazine)s, or PHTs, these can be dissolved in strong acid, breaking apart the polymer chains into component monomers that can then be reassembled into new products. Like traditional unrecyclable thermosets, these new structures are rigid, resistant to heat and tough, with the same potential applications as their unrecyclable forerunners.

      Although no recycling is 100% efficient, this innovation – if widely deployed – should speed up the move towards a circular economy with a big reduction in landfill waste from plastics. We expect recyclable thermoset polymers to replace unrecyclable thermosets within five years, and to be ubiquitous in newly manufactured goods by 2025.

Research Trend : 360-Degree Infrared Vision

Michael Dortch was building video surveillance trailers for industrial parks in Colorado when his clients started asking for near-omniscient views of their properties. They wanted to see intruders in the dark from all angles, but such coverage required up to seven thermal infrared cameras and cost more than $100,000. So Dortch and a colleague spent four years developing a cheaper, more capable alternative. Their Thermal Radar system provides 360-degree infrared coverage that can spot people, fires, vehicles, and more.

A finished unit will cost about $16,000—many times cheaper than any system that comes close—and should be ready for its debut later this year. The first and biggest market will be corporate security. But the forest service, the Utah Department of Transportation, and even the Pentagon, Dortch says, also have his invention on their radar.

Research update: The Anti-Slouch Screen

If you slump down when you’re typing on an ErgoSensor monitor by Philips, it’ll suggest that you sit up straighter. To help office workers avoid achy backs and tired eyes, the device’s built-in camera follows the position of your pupils to determine how you are sitting. Are you too close? Is your neck tilted too much? Algorithms crunch the raw data from the sensor and tell you how to adjust your body to achieve ergonomic correctness. The monitor can also inform you that it’s time to stand up and take a break, and it will automatically power down when it senses that you’ve left. - #IJSTE
