Atmospheric carbon dioxide (CO2) levels have increased dramatically in the last few decades. Famous for causing global warming, CO2 is also resulting in the acidification of seas and oceans. This disturbs the rich life of the marine ecosystem, which affects human communities dependent on this environment for their livelihood. For islands like Malta and Gozo, this problem is particularly important. This ‘silent crisis’ has attracted the X-prize Competition organisers who have set a $2 million dollar prize to be awarded to anyone that can develop stable, inexpensive, and precise acidity (pH) sensors to help understand the acidification of marine environments. At the same time, a European COST initiative (Supramolecular Chemistry in Water) is encouraging the design of water-soluble molecules which can recognise analytes. Most chemical sensors do not perform well in water.Continue reading
In Malta, buildings cover one third of the Island, leaving greenery in the dirt track. Green roofs are one way to bring plants back to urban areas with loads of benefits. Antoine Gatt, who manages the LifeMedGreenRoof project at the University of Malta, tells us more.
Soil sustains wildlife, landscapes, crops, forests, and air and water quality. Our survival and development depends on soil. However, a large amount of metals is being released daily into the environment through household waste, agricultural practices, and industrial activity.
Soil acts as a ‘sink’ for pollution, and depending on the soil’s chemical conditions, metals may persist there for long periods of time, posing a risk for humans and ecosystems. Maltese soils have a high concentration of lead, zinc, and copper. At high concentrations, these metals are harmful to many forms of life and can lead to a host of diseases including cancer. Carmen Sanchez Garcia (supervised by Dr Anthony Sacco) studied how to reduce the level of these metals in Maltese soils using plants instead of conventional methods.Continue reading
All over the world, hip replacement surgeries are on the increase. Provisional data from the hip replacement register at Mater Dei shows that, in Malta during 2014, 145 people needed their hips replaced while another 11 needed revisions to old implants. With costs that run into the thousands, the problem of faulty implants caught the eye of a local research team of engineers and medics. Cassi Camilleri finds out more about their work in solving the dilemma. Photography by Elisa von Brockdorff
The Valletta 2018 Foundation recently started a five-year research study to evaluate and monitor the European Capital of Culture (ECoC) project in Malta. The process combines both quantitative and qualitative approaches to collect data that will be communicated to the general public and interested stakeholders. This research will provide feedback to help fine-tune or correct the Foundation’s operations. The process aims to provide a local model for research in culture and the creative sector in order to encourage more cultural research after 2018.Continue reading
Language,translation,and education: three hot topics on the Maltese Islands.
Malta invests heavily in education with a big chunk of its budget, strength, and efforts invested to elevate standards. Malta is also largely bilingual. This is even reflected in Malta’s constitution which places both Maltese and English as official languages. Yet, deciding on which language to use to teach children is a thorn in the side of Maltese educational institutions. A viable bilingual policy is still needed.
The European Union places great importance on national languages. This policy elevates the importance of all EU languages no matter the country’s size. The EU releases its documents in each language—a boon for Maltese translation studies. However, there is a clear lacuna in terminology and glossaries for education documents.
Jana Galea (supervised by Prof. Anthony Aquilina) translated an international publication on education into Maltese and compiled an accompanying glossary of educational terms. Translators have to adopt the role of terminologists (professionals who research and locate information or past publications to ensure accuracy and consistency in the usage of terms) when working with specialised terminology, a time consuming activity due to the lack of standardised terms. A glossary of educational terms facilitates translation by providing an easy-to-access reference tool that ensures consistent terminology in translations.
The research tries to show that Maltese and English should not be seen as rivals constantly trying to outdo each other. The Maltese language is part of the country’s unique identity, its most democratic tool, and an official EU language. It is strong and continuously growing, as Prof. Manwel Mifsud stated ‘Ilsien żgħir imma sħiħ, ilsien Semitiku imma Ewropew, ħaj u dinamiku’ (A small but complete language, a Semitic language but European, alive and dynamic). Then there is the English language which is Malta’s main linguistic link to the rest of the world and the carrier of scientific, technological, and informational developments—both languages enrich the Maltese Islands.
This research was performed as part of a Master of Arts in Translation at the Faculty of Arts, University of Malta. It is partially funded by STEPS (the Strategic Educational Pathways Scholarship—Malta).

Video streaming uses a lot of bandwidth. Internet service providers can either limit bandwidth or provide more. To bypass this problem newer encoders aim to compact video into smaller packages, to keep the same video quality but a smaller size.
The problem is the variety of video devices available that range from mobiles, tablets, and high definition TVs. This diversity results in various different video transmissions being needed. To avoid encoding the same sequence several times and reduce the traffic over a network, video coding called H.264/Scalable Video Coding (SVC) was introduced. This type of video coding allows a single stream to encode for time, space, and quality. This technology saves bandwidth. SVC is expected to become the standard for Internet streaming. The only thing holding it back is the need for a complex encoder.
Kurt Abela
Kurt Abela (supervised by Dr Ing. Reuben Farrugia) proposed the use of a Graphics Processing Unit (GPU) based encoder to speed up the encoder. The Block Motion Estimation (BME) module within SVC takes up the bulk of the total encoding time in standard H.264/AVC. Abela designed certain modules to be optimised for NVIDIA GPUs. Through an asynchronous programming model, the video encoder could be run simultaneously on the CPU (Computer Processing Unit) and GPU. By using this novel encoder, encoding was sped up at most 436x times, when compared to a reference model, with no loss in quality. The encoder was sped up even more with further improvements to allow real-time HD video encoding.
This system is much cheaper and easier to use than leading alternatives. GPUs are very cheap and already found in most computers. Further developments on GPUs could soon see them replace more expensive encoders in datacentres.
