to win the World Cup the street parties would last for days. Our cover story (pg. 48) looks into the background behind this relationship. The flipside of this bond has been a strange dislike of the French. The story goes that back in 1798 Napoleon invaded Malta and stole its riches—a history influenced by the Church and British colonisers who had separate but overlapping agendas. Our

cover story focuses on Dr Charles Xuereb’s research, which tries to uncover what has blocked Malta’s memory of the French and what can be done to change this oftennegative view. The issue is packed with other features. Dr Maria Galea tells us about Maltese Sign Language (pg. 42). Her research helped bring a logical framework to the written form of the language, which can help around 400 deaf people in Malta.

Anne Marie Dimech writes about Dr Gabrielle Zammit’s work on bacteria that took her from the cliffs of Dwejra, Gozo to Malta’s ancient underground catacombs (pg. 20). The broad range of stories reflects the diversity of research at University. But at THINK we felt we had to go further. Apart from stories from student articles (pg. 17-19), features, reviews (pg. 56-61), and opinion pieces (pg. 12-16), we are introducing Toolkit (pg. 4) that highlights University’s best equipment, Design (pg. 10)

Malta: Stockholm Syndrome (or why we love the British) The cover is a social commentary on Malta's distorted collective memory. The Sette Giugno monument, previously placed in St George's Square and currently situated in Hastings Garden, Valletta is one of the few monuments which symbolises Maltese revolt. The photograph shows the monument's reverse side—a side usually forgotten, much like the monument and what it represents. Photography and image composite by Jean Claude Vancell.

Mecon M

econ is an ongoing research project for the 2015 edition of the IASS EXPO, themed

Future Visions which is to be held in Amsterdam between June and August 2015. The project is to design and build a structurally innovative, deployable pavilion in a bid to celebrate Future Visions in the field of engineering design and innovation. Mecon is the solution created by a team of five recently graduated architects. Mecon is a deployable structure which transforms from a cube into a truncated octahedron (mecon is a term coined by Buckminster Fuller). The change in geometry increases its volume thrice which opens a host of new applications. Each cube is only capable of transforming into the mecon if its edges are equal in length and follow a specific path dictated by the unique joints the team designed. The transformation is simple, and the joints can be scaled to produce a mecon of any size, but for the EXPO the team had to abide by strict weight, size, and transportation restrictions. Mecon has only been possible thanks to the support of Prof. Alex Torpiano and Prof. Dion Buhagiar (Faculty for the Built Environment), and Prof. Joseph Grima and the Auxetics Research Group (Faculty of Science, University of Malta), and Lee Bullock from Proto+. After the expo, the pavilion will be reassembled in Malta. If interested in exhibiting this structure, please contact team@mecon.space and like the Facebook page www.facebook.com/mecon.space Design

The Mecon pavilion, consisting of three modules, will be suspended at the Muziekgebouw in Ambsterdam (above and top).

Cyanobacteria are believed to have been among the first living organisms to colonise the earth and to give it its oxygen-rich atmosphere. This eventually let human beings and a host of other animals evolve. Cyanobacteria are unique in being bacteria that can phosynthesise, glide without the aid of flagellae and fix nitrogen through specialised cells, while adapting and surviving in hostile environments. Apart from their importance in evolution, cyanobacteria have recently come back into the spotlight because of wide-ranging biotechnological applications. They are being studied to make biofuels and help degrade plastic. They are also used in the production of cosmetics and lubricants. Molecules made by these bacteria have shown antiviral, antibacterial, antifungal and anticancer properties that can lead to the production of new medicines.

Zammit is presently collaborating with medical geneticist, Professor Alex Felice to sequence the whole genomes of these new strains of cyanobacteria and microalgae.

Her love of Malta’s natural and cultural heritage has driven her work to safeguard Malta and its environment. Although one person’s research is only a sliver in the contribution to scientific knowledge, every step is vital to create a picture that can save others, and perhaps with these efforts nature will provide yet another medicine.

MRI Physics A SUMMARY

MRI is a non-invasive medical test that aids doctors and physicians in their diagnoses and treatment of various medical conditions. During an MRI scan, the subject lies in a strong magnetic field with radio-frequency waves directed at them. The magnets in the MRI scanner line up the protons (H+ ions) in the body in the same direction because they are sensitive to a magnetic field. Short bursts of radio waves are then sent to particular areas of the body, knocking the protons out of alignment. When the radio waves are turned off, the protons then realign and in so doing they send out radio signals, which are picked up by receiver coils. These signals provide information about the exact location of the protons in the body. Then, in the same way that millions of pixels on a computer screen can create complex pictures, the signals from the millions of protons in the body are combined to create a detailed image. These images enable physicians to evaluate various parts of the body and determine the presence or

So we really have to invest more in screening people.’ In Germany, regular screenings help identify disease before it becomes incurable. This regular testing also provides a wealth of data for researchers to develop a better understanding of various diseases. In Malta, this has not been adopted systematically.

There is no denying that care is crucial. However, being able to differentiate between diseases better and earlier will prove essential in the long-run. It is about working backwards and trying to improve on what is already known to develop better treatments and improve people lives. As Sonia rightly says, ‘It’s about taking the bull by the horns.’

CONNECT THE DOTS A new hallmark for graphene, the wonder material of the 21st century, has been found. It has a range of applications—from biomedical to new, smart materials.

he crumpled paper in the dustbin next to your office desk appears like a mundane object. However, if you grab a piece of paper and pull from both ends to open it up, it will grow longer and fatter. This

seemingly unremarkable property could result in the next revolutionary material. Professor Joseph Grima is one of the leaders in the field of auxetic materials. He starts by explaining the obvious. When something is stretched it tends to become longer and thinner. Auxetics defy this logic. They become wider when stretched. The extent to which a material gets fatter or thinner is called the Poisson’s ratio. A positive Poisson’s ratio is when the material gets thinner, a rubberband is a good example; while if a material widens when pulled it has a negative Poisson’s ratio. This makes a material auxetic. This property is ‘scale independent,’ explains Dr Daphne large and small structures.

explains how graphene is a form of carbon made of single atom-thick layers. They appear like sheets of paper with clouds of electrons on each side. These are really thin layers, graphene is amongst the thinnest materials that ever existed. One graphene layer, for example, is invisible to the human eye being thinner than a soap bubble film, yet nearly as strong as diamond. This unique structure combines strength with an ability to pass electricity and heat. Thus making it promising for several future applications.

MAKING THE CONNECTION Grima compares graphene sheets to the sea in autumn. The small ripples on the surface of the sea resemble graphene sheets, which are not perfectly flat. Graphene has ripples in it. Nevertheless, unlike the crumpled paper mentioned before, graphene is not naturally auxetic. It does not get wider when stretched. Grima’s team shows how graphene’s

The presence of these pentagons geometrically disturbs the graphene sheet, which dramatically increases the amount of ripples. Grima’s team succeeded in showing that putting enough defects in graphene imparts it with auxetic properties. As a result of these defects, ‘the imperfect graphene’ adopted a real crumpled shape, giving it the necessary geometry similar to that of a ‘highly wrinkled paper’, so that when one stretches it, it also widens, explains Grima.

These points relate to the 1st (I/me), 2nd (you), and 3rd person (he/him) person. Now by pointing to these (with an index finger) a signer can create pronouns: me/I, you, and him/her. Coupled with this, there are a certain group of verbs in Maltese Sign Language that ‘agree’ with these points. The hands move towards these points and sort of ‘attach’ (or affix) to them. So in a verb like STAQSA (ASK), the hand is not an index finger shape but more like the handshape of the OK

Maltese Sign Language agreement verbs need to be properly marked in SignWriting in order to be read with ease. This is because, within what looks like a single sign, often multiple elements can be marked. Just as the single Maltese word fakkarthiela (the equivalent in English of ‘I reminded her of it’) is made up of the verb ‘fakkar’ (to remind) ‘t’ (past tense plus 1st person singular ‘I’) ‘hie’ (feminine ‘it’) and ‘lha’ (to her), the same sign can simultaneously indicate subject, object, as well as adjectives and adverbs.

MALTA

Stockholm Syndrome (or why we love the British) Between 1798 and 1800, Malta changed hands three times. The feudal Knights were easily replaced by Napoleonic France, whom the Maltese initially welcomed, then revolted against a mere 82 days later ushering in the British Empire. 'Why?' is a mystery lost in the history books that gloss over the period demonising Napoleon while exalting the British who ruled Malta as a colony till independence in 1964.

Xuereb contrasts this with Canon Panzavecchia’s account published in 1835, the first Maltese point of view of the reviewed period. Panzavecchia, who was one year old in 1798, influenced many subsequent history books. Panzavecchia describes ‘two years of calamitous occupation’ after an invasion that saw Bonaparte trick the Order into submission. He also mentions a degrading convention, with the Maltese being forced to sign an unfavourable treaty to integrate Malta as part of France in 1798. He forgets to mention the benefits Napoleon

NOTEWORTHY PEOPLE TO REMEMBER Mikiel Anton Vassalli (1764–1829) needs to remembered with a monument in Valletta. In Paris there is a new authentic description of Vassalli that Xuereb found in 2013. Vassalli was not just as a linguist but as a patriot and politician. He has not been wholly rehabilitated. Another monument should be dedicated to the 10,000 people who perished between 1798–1800 no matter which side they fought for. They should be included in a monument that remembers the event without taking sides.

head left on a spike. Xuereb thinks that the clergy and traders bought the services of mercenaries. They then used them to tie the hands of the Maltese peasants into a fully-fledged countryside revolt. These mercenaries were probably the very slaves Bonaparte’s reforms had just freed. On 1st September 1800, Alexander Ball estimated 3,000 troops were occupying the front posts besieging the French. The author Cavaliero had stated that Bonaparte had freed around 2,000 slaves—1,400 Moors and 600 Turks—who would have been treated brutally before being freed, much more likely culprits to the

fort and port. When the French surrendered due to the combined efforts of a British sea blockade and Maltese-led land siege, the Maltese were not involved in any treaties. The 5th September 1800 capitulation basically signed Malta off to the British. The British were meant to leave, but did not—not that the Maltese wanted the Order back. This handover was cemented in 1814. In the meantime the Maltese tried to claim their political rights but failed. Malta was deemed unfit to govern itself. The Catholic Church supported British rule in Malta; an uneasy relationship at times, since the Church still owned one third of their colony. However, ‘the British had a trick with

CORRECTING THE COLLECTIVE MEMORY

Feature

The French came to liberate the Maltese from a despotic, ailing Order from the feudal era. Vassalli’s nationalistic aspirations made this possible. After the French Revolution, a republican system of government was put into place in Malta to secularise administration and give people rights. Ecclesiastical leaders aided by the British Navy in the Mediterranean stopped all of this progress and restored privileges to the elite, justifying the counter revolt by demonising the French as anti-religious and anti-Maltese. As a result, public education was delayed for another 80 years and representative government for more than a century. Malta was humbled into a fortress colony and its people deemed unable to govern themselves.
