The One-Page Proposal BT Young Scientist & Technology This lesson discusses the process involved in submitting entries to the BT Young Scientist & Technology Exhibition. The requirement to carry out careful and detailed planning which will inform the mandatory one-page proposal is stressed. The critical importance of the one-page proposal is central to the lesson.
Generating renewable energy ESB The term ‘sustainability’ relates to the need to ensure that we do not deprive future generations of essential energy resources by using them up or by damaging the environment in an irreversible manner. The obvious way of ensuring sustainability is the use of renewable resources.
HPV Vaccine – benefits and efficacy Health Service Executive HPV vaccine safety has been monitored for more than ten years and is continually reviewed by many international bodies including: the European Medicines Agency; the Global Advisory Committee on Vaccine Safety of the World Health Organization; and the Centers for Disease Control and Prevention in the US.
Fish Farming and Aquaculture BIM Aquaculture, the husbandry of animals and plants in aquatic environments, is also an important industry. Ireland has an abundance of aquatic environments suitable for aquaculture ranging from its extensive and varied coastline, to its abundant inland waterways.
Remote patient monitoring Boston Scientific The quality of life of patients with long term or chronic conditions is generally much greater if they can stay in their own home. They maintain contact more easily with family and friends and have a greater degree of freedom. With the benefit of RPM (remote patient monitoring) it is possible to quickly advise the patient or family members on what action to take if a problem arises.
Short Range Radio Device Communications Commission for Communications Regulations Today SRDs or ‘short range (radio) devices’ are in common use. These devices use low power RF (radio frequency) in specified RF bands. They are not likely to cause harmful interference to other networks or to essential public services and so no licence is required for their use.
Minimising energy loss in power transmission Eirgrid Metallic conductors, such as copper and aluminium, carry the electric current to our homes and places of work. However, some energy is lost along the way as heat because even the best conductors have some electrical resistance. These losses have been reduced from about 13% in 1960 to about 7.5% in 2016. Can we reduce these losses even further?
The Future-Ready Workforce Dell EMC Over a relatively short period of time the Information Technology (IT) industry has emerged as a significant influence on a changing workplace. This lesson discusses some of the features of this change such as mobility, remote working and technologies driving these. The concepts ‘Bring You Own Device’ and ‘Activity Based Working’ are also explained.
Resource efficiency EPA Today we face potential shortages of food, water, fuel, timber and critical materials. Historical events have been driven by drought, famine and climate events, and continue to be. Our current wasteful use of the limited available resources cannot be sustained.
Inflammatory Diseases MSD The innate immune system is always ready to fight infection while the adaptive (or ‘specific’) immune system is activated when the innate system fails to stop infection. Inflammatory disease can be caused by an autoimmune response in which the body’s immune system attacks normal healthy tissue mistaking it for a pathogen.
Layered Mapping Ordnance Survey Ireland Maps are used for decision making in many areas of activity such as flood control, mineral exploration, housing and education. Layered mapping allows the user to place different geo-spatial data sets onto a map in layers. The lesson describes the GeoHive – a web platform that facilitates this process and instructs the student on its use.
What is multiple sclerosis? Perrigo In multiple sclerosis the myelin sheath surrounding neurons is attacked by the body’s defence systems resulting in the slowing down of the signal or even its blockage. Even if a signal is just slowed down it will cause responses to go out of synch and become ineffective.
Climate change ― an overview Teagasc The Earth’s climate has always been changing. However, scientists have now concluded that there is a 95% probability that the global warming of the last 50 years is due to man-made greenhouse gases (GHGs). This is because the Earth’s natural greenhouse effect has been enhanced by these emissions.
They imagined their discoveries... BT Young Scientist & Technology With over 50.000 visitors, the BT Young Scientist and Technology Exhibition, showcases some 550 student projects. This lesson provides first-hand accounts from three previous prize winners – two groups and one individual – who describe the unique, fascinating, and often life-changing, experience in their own words.
Sustainability in Irish Fisheries BIM The maximum sustainable yield from a fishery occurs when the rate of reproduction of the fish is at a maximum. This occurs at half the carrying capacity of the fishery. A fish stock can be compared to an investment fund. If interest is withdrawn from it faster than it accumulates then the fund declines. Several fish stocks in the sea areas around Ireland are overfished.
Kidney stones and how to remove them Boston Scientific Kidney stones can often be shattered using a non-invasive procedure called shock wave lithotripsy. The shattered pieces are then eliminated naturally from the body. High energy sound waves are focussed on the stone for about an hour at the rate of about 1 pulse per second.
What is broadcasting? Commission for Communications Regulations Radio signals, like light, are electromagnetic. They do not require a medium and they travel at about 300 million metres per second. The frequency of radio signals ranges from about 100 kHz to beyond 1000 MHz. The corresponding wavelengths range from 3000 metres to 0.3 metres.
Understanding electricity Eirgrid Volts, amperes and watts are related as follows: watts = volts × amperes. This lesson explains the meaning of these units and why they are related in this way. It also highlights how the unit of electric charge (the coulomb) relates to volts and amperes.
The Internet of Things EMC The topic of this lesson is the ‘Internet of Things’(IoT), also known as the ‘Internet of Everything’. The lesson describes the purpose of the IoT and the characteristics required by ‘things’ in order to operate effectively in that environment. The innovative EMC test platform is also described.
Septic Tanks EPA This lesson outlines the structure and operation of septic tanks. It describes primary, secondary and tertiary treatment processes. Septic tanks are so unobtrusive that they are easily forgotten and this can lead to major problems. All septic tanks must now be registered with the local authority. The EPA supervises the inspection of the tanks by the local authority.
Meningococcal disease Health Service Executive Meningitis is an inflammation of the meninges — three layers of tissue that surround and protect the brain and spinal cord. The classical symptoms of meningitis are fever, vomiting, drowsiness, feeling confused and irritable, stiff neck and photophobia. The final two symptoms are often absent in small children.
Ecology and Social Responsibility Iarnrod Eireann When carrying out project or maintenance works on the railways it is important to conduct ecological surveys beforehand in order to plan correctly and assign appropriate mitigation measures. Quantitative, qualitative or semi quantitative surveys set a baseline indicator of biodiversity in specific localised areas.
Coding and Mapping Ordnance Survey Ireland This lesson deals with the topic of coding and discusses some of the principles involved. An example of the ‘object oriented’ concept is presented and the object-oriented spatial database Prime2, Ireland’s National Spatial Platform, is described. The OSi project with CoderDojo and Minecraft is outlined.
Health and Safety at Work Siemens Health and safety in the workplace is the topic of this lesson. Having underlined the critical importance of workplace incidents to economic and social wellbeing, the ‘Siemens Zero Harm’ policy is described. This highly effective strategy is the legacy of Werner von Siemens, founder of the famous global engineering company.
Antibiotic resistance Health Products Regulatory Authority In the past thirty years only two new classes of antibiotics have appeared and so the problem of antibiotic resistance is becoming more serious. The World Health Organisation has classified it as a ‘serious threat that has the potential to affect anyone, of any age, in any country’.
Science and Serving People Mark Pollock Trust Although blind, Mark competed in ultra-endurance races across the globe and rowing in the Commonwealth Games. In 2010, a tragic a fall left him paralysed. This lesson outlines his story and describes his current exploration of the application of scientific knowledge to the treatment of spinal cord injury.
Soil Classification Teagasc Soils can now be classified using the World Reference Base (WRB) for soil resources. It draws on ideas from the USDA, Russian and other systems. This system recognises 32 basic reference soil groups. Globally, the WRB system can be used as a benchmark.
Be Inspired and Take Part BT Young Scientist & Technology This lesson describes how the BT Young Scientist & Technology Exhibition promotes scientific inquiry. It emphasises the importance of developing your curiosity about the world around us and outlines how to take part in the exhibition.
The Electric Car ESB This lesson explores the evolution of the electric car, the science and technology behind it and the reasons why it is becoming more important to modern life. Key components are the electric motor and the battery, and there is ongoing research to make them more efficient. An A3 poster on ecars is also included.
Managing our Marine Resources BIM With an estimated 80% of species in EU waters being overfished it is essential that our fisheries work in a sustainable manner to ensure that our marine resources are kept in good health for future generations. In order to do this a detailed understanding of marine ecology is required.
Biocompatibility of Medical Devices Boston Scientific Medical devices that are implanted in the body generally come into contact with a variety of tissues and their interaction with each tissue type must be taken into account so that there is maximum benefit with minimal adverse reaction. This lesson considers some of the issues associated with biocompatibility.
Radar and its Uses Commission for Communications Regulations Air traffic control, weather forecasting and navigation are among the most important applications of radar. The lesson outlines the basic principles of radar systems. ComReg regulates the allocation of the hundreds of RF bands that are used for TV and radio, mobile phones, radar, meteorology and satellite communications.
Compliance and Standards in Business CRH Ethical behaviour in business, no less than in everyday life, is often taken for granted but the consequences of unethical activity are so grave, as evidenced by the financial crash, that it is vital to set up compliance programmes that promote and support ethical behaviour at all levels of business.
Agriculture and Climate Change Department of Agriculture, Food and the Marine Agriculture’s most significant contributions to global greenhouse gases are due to methane (8.6%) and nitrous oxide (5.5%). In fact agriculture is the most significant source of these gases. While agriculture itself contributes relatively little to CO2 levels, changes in land use make a much greater contribution (12%).
The 3rd Platform EMC The term ‘3rd platform’ refers to the revolution in information and communications technology brought about by modern mobile telecommunications in conjunction with online applications and ‘cloud’ based storage.
Ionising Radiation and Health Hazards EPA Electromagnetic radiation whose wavelength is less than about 300 nm is called ionising radiation because it can knock electrons off some atoms and molecules causing ions to form, or to be more precise, ion pairs. Ionising radiation can damage bio-molecules such as DNA, causing cells to malfunction or die.
Pertussis (Whooping Cough) Health Service Executive Pertussis is a serious and very contagious bacterial disease that can last for up to three months. Children are most commonly affected. It can be prevented by a course of vaccination. Outbreaks recur when the percentage of people vaccinated falls.
Using Bacteria to make a Biomolecule MSD Interferon inhibits cell proliferation and so has anti-cancer properties. In order to make it DNA coding for interferon is introduced into E. coli bacteria which multiply and produce commercial quantities of interferon. The cells are regularly harvested and the interferon extracted. Genetic modification of the bacteria is necessary as otherwise they would destroy the interferon, a protein foreign to them.
Mapping for Climate Change Ordnance Survey Ireland Severe flooding events in recent years have highlighted the importance of maps that show the likely extent of flooding for a given rise in water level. OSi generates maps from a database that is constantly being updated with data from total stations, GPS receivers, lidar, 3D scanners etc.
Carbon Capture and Storage Shell The term ‘carbon capture’ refers to processes in which CO2 is captured at source with a view to storing it permanently, typically underground. Anthropogenic CO2 comes mainly from fuel combustion and so research in this area has focused on capturing CO2 before, during or after the main combustion process.
Wind Turbine Technology Siemens Wind power has been the most rapidly growing form of energy in Ireland over the past ten years; installed capacity has risen from about 600 MW (in 2004) to 2190 MW (in 2014). Wind power is generally greatest in Ireland during winter when the demand is highest − in contrast to solar power.
Microorganisms – can we live without them? Teagasc Apart from helping digestion, gut bacteria benefit us in many other ways. They aid the development of some immune system cell types and they reduce the risk of allergies. They are affected by what we eat and our level of activity. Gut bacteria benefit us in so many ways that our health depends on them.
The Future is Mobile Vodafone There were no mobile phone subscribers in 1982. Today, some thirty years later, while 18% of the world’s 7 billion population do not have electricity and 20% cannot read or write, nearly 85% have mobile phones. This extraordinary situation illustrates our fascination with the mobile.
Let the Robots do the work Boston Scientific Robotic machines first appeared in the manufacturing industry in the 1950s. Since then, there has been significant scientific and technical advances in robotic design and functioning. This lesson looks at this historical evolution and describes the fundamental physics and mechanics involved.
HPV — Human Papillomavirus Health Service Executive Cervical cancer is responsible for the deaths of some 250,000 women each year and most are a consequence of HPV infection. This lesson outlines the range of papilloma viruses and describes how vaccines can provide a very high degree of protection.
Treating Arthritis Pfizer Some 100,000 people in Ireland are known to be suffering with arthritis and many more are claimed to be undiagnosed. This lesson looks at the impact of arthritis on skeletal joints. The various types of the disease are described — osteoarthritis, rheumatoid arthritis, fibromyalgia, gout, lupus and ankylosing spondylitis.
The Bovine Genome and Human Nutrition Teagasc Food quality is important for both human health and Irish export sales. Genomic analysis of cattle, as carried out by the ICBF, allows scientists to design specific breeding regimes and to predict the quality of beef and milk. This lesson deals with human nutrition, cattle breeds in Ireland, the impact of genomic science and genomic profiling.
The Digital Universe EMC This lesson discusses the difference between ‘data’ and ‘information’ and describes how an analogue entity is digitised. The function of the microprocessor is discussed along with the meaning of terms such as machine language’. This leads to the topic of computer programming.
Xrays: Uses and Dangers Radiological Protection Institute of Ireland The use of X-rays in any situation carries some risk and accordingly such use is carefully monitored by the RPII. This lesson describes the nature of X-rays and their position in the electromagnetic spectrum. The production of X-rays for medical application is discussed.
How Chemistry Serves Society Shell Many industries are founded on chemistry and this lesson describes how chemistry underpins many processes. The concept of the chemical formula is examined and the terms ‘chemical formula’ and ‘structural formula’ are differentiated.
The Wonderful World of Maps Ordnance Survey Ireland Maps have played a critical role in the evolution of human society. This lesson from OSI discusses the history of mapping and outlines the various techniques utilised. The mathematics of triangulation is explained and the great Irish survey of the mid 19th century is described.
All you need to know about Wi-Fi Commission for Communications Regulations This lesson deals with some of the technologies behind the Wi-Fi phenomenon. Various types of network are defined, the various devices in a wireless LAN are described and the term ‘hotspot’ is discussed. Some radio fundamentals are reviewed.
Science, Technology and Sustainability CRH Sustainability is a critical concern for social, economic and environmental reasons. The lesson focuses on the processes involved in the production of cement. It describes the measures taken by CRH to control energy use and atmospheric emissions such as dust and greenhouse gases.
Keeping the Lights on Eirgrid This lesson describes the function some of the main components of the national power grid. The conductivity of materials constituting a multi-core power cable is described. The lesson then describes how these cables are supported on the steel pylons and discussed the function of insulators.
Air Quality EPA Irish wind patterns generally ensure that the quality of the air we breathe is good. Nevertheless, modern urbanisation and industrialisation can have negative effects on it. This lesson identifies sources of pollution and the effect that pollutants have on the environment.
Penicillin: A Life Saving Antibiotic Teva Ireland The world of pharmaceuticals was changed forever when Alexander Fleming discovered penicillin in 1928. The TEVA lesson describes the background to this discovery and the subsequent impact of the antibiotic. Penicillin chemistry is discussed and its effect on inhibiting the development of pathogenic bacteria is described.
The Miracle of The Eye Novartis This lesson deals with the function and operational components of the human eye. It describes the structure of the eye and outlines how images are formed. The function of rod and cone cells, spectral range and the formation of colour vision are described.
Filling a Vial - What could be Simpler? Genzyme Genzyme are constructing the modern high-tech production line to fill the familiar glass vials that contain pharmaceuticals. This is a tightly controlled industrial process involving the removal of pyrogens, freeze drying. These processes are described and the chemistry behind them is examined.
Protecting us from noise EPA This lesson outlines the adverse effects and cost of noise. The EU Directive on Environmental Noise (Directive 2002/49/EC) set out a common approach across the EU to reduce the harmful effects of environmental noise.
Firmware At Work Boston Scientific This lesson examines some of the elements that contribute to the revolution in intelligent technology — such as software, firmware, robotics, microcode, miniaturisation, microprocessors — and indicates some exciting developments that are underway.
Using the Radio Spectrum Commission for Communications Regulations In this lesson we look at the radio spectrum and the communication services that depend on it. We also discuss the role of ComReg in managing the use of the spectrum and the need for such management. An extra Poster Sheet on ComReg is included in the folder.
