Prof. Lal Tennekoon

Professor Basil Laliputhra Tennekoon, Emeritus Professor of Civil Engineering at the University of Moratuwa, was called to rest on 30 March 2025 at the age of 82. He was educated at S. Thomas’ College, Mt. Lavinia, where he won the Miller Mathematics Prize in 1960, an achievement that gets one’s name on a board in the college hall. The prize is named after Rev. Edward Miller, the fifth warden of the school, who had read mathematics at Cambridge. Young Tennekoon fulfilled this early promise, obtaining first class honours in civil engineering from the University of Peradeniya in 1965. There were many Thomians who entered the engineering faculty with him, including Shanthi Kumar Rasaratnam (now holding an MBE for services to water engineering in the UK), Mano Ponniah (who later played first class cricket for Cambridge and All-Ceylon), and Gerard Rodrigo (subsequently a Marxist development economist).

Lal Tennekoon went on to complete his PhD at Cambridge University in 1970, on the behaviour of foundations on sandy soils. Other notable Peradeniya graduates/academics who completed PhDs in Cambridge around this time included Alagiah Thurairajah (1962, on shear properties of soils), Munidasa Ranaweera (1969, on the finite element method applied to limit analysis) and Vickramabahu Karunaratne (1970, on plasma physics) – halcyon days for Peradeniya engineering, no doubt. For six years after his PhD, Tennekoon was attached to the Faculty of Engineering at Peradeniya, teaching at both undergraduate and postgraduate levels. He joined the Katubedda Campus of the University of Sri Lanka in 1975 and became a Professor of Civil Engineering at the University of Moratuwa in 1984 and Senior Professor in 1994. Moratuwa was fortunate to obtain his services. When I once suggested that his moving to Moratuwa was a result of “the best people gravitating to the best places”, his rejoinder was that he would have found it difficult, after he got married to Preethi, to keep pace with Thurairajah’s work ethic in the Peradeniya soil mechanics lab!

He guided the fortunes of the Civil Engineering Department as its Head from 1980 to 1985, during which time the annual undergraduate intake was increased from 50 to 100, and a new civil engineering complex was constructed to accommodate that increase. He also steered the Faculty of Engineering as its Dean for 10 months in 1994/1995, when there was sharp division in the university regarding the continuation of the NDT programme within the Faculty.

Professor Tennekoon’s main research interests were based around the problems facing the geotechnical engineers of this country. These were in the areas of: (i) Shallow foundations in low lying areas containing peat and organic clays; (ii) Pile foundations terminating on rock; (iii) Landslides and the stabilisation of slopes; and (iv) Site Investigations for all types of civil engineering structures. He also chaired the Moratuwa University’s Senate Research Committee from around 1998 to 2002 and was responsible for setting up the Research Awards Scheme, which contributed significantly to raising research quality at the university.

Over his illustrious career, he provided assistance to many development projects in the country during their planning, design and construction stages, in the collection and interpretation of geotechnical data. Notable contributions have been in (i) the Environmental Improvement Project for the city of Colombo; (ii) the Southern Highway Project from Colombo to Matara; (iii) the Beira Lake Restoration Project; and (iv) several multi-storeyed building projects such as Ceylinco Celestial Towers, Crescat Towers, HNB Tower, Bank of Ceylon Tower, Central Bank Tower and Havelock City Project. He worked closely with Geotech (Pvt) Ltd, where his close friend Eng. Parakrama Jayasinghe was Managing Director. At times he enlisted the services of his colleagues, most of them his juniors. The consideration paid by this senior engineer to the disciplinary competencies of his younger associates only served to increase our own reciprocal respect for him.

Professor Tennekoon served as the principal author for the development of two standards for the Institute of Construction Training and Development (ICTAD), in which his research findings were also incorporated. The two standards were in the areas of ‘Site Investigation’, and ‘Pile foundations end bearing on rock’; and were published by the Sri Lanka Standards Institution (SLSI). He was a Founder Member of the Sri Lanka Geotechnical Society (SLGS) in 1987; and held its Presidency from 1994 to 2000. He was recognised for his contributions to the Geotechnical Engineering profession in Sri Lanka by the SLGS at an International Conference organised by the Society in 2007. The Institution of Engineers Sri Lanka bestowed on him an Award for Excellence in 2008. He was elected a Fellow of the National Academy of Sciences of Sri Lanka in 2013.

In April 2003, Professor Tennekoon was invited by the Government of Sri Lanka to be part of a team for implementing the World Bank funded project for the Improvement of Relevance and Quality of Undergraduate Education (IRQUE). This was a 6-year project where the major component was the establishment of a Quality Enhancement Fund (QEF). This was to be a strategy in which quality and relevance were to be improved through the entire university system by the implementation of a competitive funding scheme. Professor Tennekoon was responsible for the implementation of this QEF component, which often involved choosing between competing study programmes. His dispassionate judgment and clinical impartiality ensured the smooth operation of this project; it also endeared him to virtually the entire university community in Sri Lanka. Some of us wondered whether he was deserting his primary calling to engineering through this involvement, but he was only broadening his horizons. He later became passionate about outcome based engineering education, and chaired the Accreditation Board of the Institution of Engineers, Sri Lanka, responsible for accrediting engineering programmes under the Washington Accord.

Twenty eight years ago, Lal Tennekoon suffered a massive heart attack and was in the intensive care unit for many days. His loving wife Preethi and his children Layanthi and Banuka rarely left the hospital premises, at times camping out on its staircases, as I recall. Theirs was clearly a very loving family. How fortunate that we all got him back from the brink of death. From a private communication he circulated to some of us soon after, I am aware that he was extremely grateful to all who attended on, ministered to and prayed for him. He himself looked after his wife caringly, eschewing all professional and other engagements, towards the end of her life. Preethi’s demise hastened his own.

Professor Lal Tennekoon was an illustrious but utterly unpretentious and much loved academic; a greatly sought after and highly respected geotechnical consultant; and a passionate advocate for outcome based engineering education. His twin concerns for practice oriented research on the one hand and engineering education on the other, continue to be nurtured by those he engaged with. His geotechnical expertise endures in the careers of his one-time students, all now emeritus or full professors themselves – Professor Anuruddha Puswewala (rock mechanics); Professor Athula Kulathilake (slope stability); Professor Saman Thilakasiri (piled foundations); Professor Udeni Nawagamuwa (environmental geotechnics); and Professor Nalin de Silva (shallow foundations).

Maduro abduction marks dangerous aggravation of ‘world disorder’

Venezuelan President Maduro being taken to a court in New York

The abduction of Venezuelan President Nicolas Maduro by US special forces on January 3rd and his coercive conveying to the US to stand trial over a number of allegations leveled against him by the Trump administration marks a dangerous degeneration of prevailing ‘world disorder’. While some cardinal principles in International Law have been blatantly violated by the US in the course of the operation the fallout for the world from the exceptionally sensational VVIP abduction could be grave.

Although controversial US military interventions the world over are not ‘news’ any longer, the abduction and hustling away of a head of government, seen as an enemy of the US, to stand trial on the latter soil amounts to a heavy-handed and arrogant rejection of the foundational principles of international law and order. It would seem, for instance, that the concept of national sovereignty is no longer applicable to the way in which the world’s foremost powers relate to the rest of the international community. Might is indeed right for the likes of the US and the Trump administration in particular is adamant in driving this point home to the world.

Chief spokesmen for the Trump administration have been at pains to point out that the abduction is not at variance with national security related provisions of the US Constitution. These provisions apparently bestow on the US President wide powers to protect US security and stability through courses of action that are seen as essential to further these ends but the fact is that International Law has been brazenly violated in the process in the Venezuelan case.

To be sure, this is not the first occasion on which a head of government has been abducted by US special forces in post-World War Two times and made to stand trial in the US, since such a development occurred in Panama in 1989, but the consequences for the world could be doubly grave as a result of such actions, considering the mounting ‘disorder’ confronting the world community.

Those sections opposed to the Maduro abduction in the US would do well to from now on seek ways of reconciling national security-related provisions in the US Constitution with the country’s wider international commitment to uphold international peace and law and order. No ambiguities could be permitted on this score.

While the arbitrary military action undertaken by the US to further its narrow interests at whatever cost calls for criticism, it would be only fair to point out that the US is not the only big power which has thus dangerously eroded the authority of International Law in recent times. Russia, for example, did just that when it violated the sovereignty of Ukraine by invading it two or more years ago on some nebulous, unconvincing grounds. Consequently, the Ukraine crisis too poses a grave threat to international peace.

It is relevant to mention in this connection that authoritarian rulers who hope to rule their countries in perpetuity as it were, usually end up, sooner rather than later, being a blight on their people. This is on account of the fact that they prove a major obstacle to the implementation of the democratic process which alone holds out the promise of the progressive empowerment of the people, whereas authoritarian rulers prefer to rule with an iron fist with a fixation about self-empowerment.

Nevertheless, regime-change, wherever it may occur, is a matter for the public concerned. In a functional democracy, it is the people, and the people only, who ‘make or break’ governments. From this viewpoint, Russia and Venezuela are most lacking. But externally induced, militarily mediated change is a gross abnormality in the world of democracy, which deserves decrying.

By way of damage control, the US could take the initiative to ensure that the democratic process, read as the full empowerment of ordinary people, takes hold in Venezuela. In this manner the US could help in stemming some of the destructive fallout from its abduction operation. Any attempts by the US to take possession of the national wealth of Venezuela at this juncture are bound to earn for it the condemnation of democratic opinion the world over.

Likewise, the US needs to exert all its influence to ensure that the rights of ordinary Ukrainians are protected. It will need to ensure this while exploring ways of stopping further incursions into Ukrainian territory by Russia’s invading forces. It will need to do this in collaboration with the EU which is putting its best foot forward to end the Ukraine blood-letting.

Meanwhile, the repercussions that the Maduro abduction could have on the global South would need to be watched with some concern by the international community. Here too the EU could prove a positive influence since it is doubtful whether the UN would be enabled by the big powers to carry out the responsibilities that devolve on it with the required effectiveness.

What needs to be specifically watched is the ‘copycat effect’ that could manifest among those less democratically inclined Southern rulers who would be inspired by the Trump administration to take the law into their hands, so to speak, and act with callous disregard for the sovereign rights of their smaller and more vulnerable neighbours.

Democratic opinion the world over would need to think of systems of checks and balances that could contain such power abuse by Southern autocratic rulers in particular. The UN and democracy-supportive organizations, such as the EU, could prove suitable partners in these efforts.

All in all it is international lawlessness that needs managing effectively from now on. If President Trump carries out his threat to over-run other countries as well in the manner in which he ran rough-shod over Venezuela, there is unlikely to remain even a semblance of international order, considering that anarchy would be receiving a strong fillip from the US, ‘The World’s Mightiest Democracy’.

What is also of note is that identity politics in particularly the South would be unprecedentedly energized. The narrative that ‘the Great Satan’ is running amok would win considerable validity among the theocracies of the Middle East and set the stage for a resurgence of religious fanaticism and invigorated armed resistance to the US. The Trump administration needs to stop in its tracks and weigh the pros and cons of its current foreign policy initiatives.

Students of The British High School in Colombo in action at the fashion show

The British School in Colombo (BSC) hosted its Annual Christmas Carnival 2025, ‘Gingerbread Wonderland’, which was a huge success, with the students themseles in the spotlight, managing stalls and volunteering.

The event, organised by the Parent-Teacher Association (PTA), featured a variety of activities, including: Games and rides for all ages, Food stalls offering delicious treats, Drinks and refreshments, Trade booths showcasing local products, and Live music and entertainment.

The carnival was held at the school premises, providing a fun and festive atmosphere for students, parents, and the community to enjoy.

The halls of the BSC were filled with pure Christmas magic and joy with the students and the staff putting on a tremendous display.

Among the highlights was the dazzling fashion show with the students doing the needful, and they were very impressive.

The students themselves were eagerly looking forward to displaying their modelling technique and, I’m told, they enjoyed the moment they had to step on the ramp.

The event supported communities affected by the recent floods, with surplus proceeds going to flood-relief efforts.

Hi! This week I’m giving you some beauty tips so that you could look forward to enjoying 2026 with a glowing younger looking skin.

Face wash for natural beauty

* Avocado:

Take the pulp, make a paste of it and apply on your face. Leave it on for five minutes and then wash it with normal water.

* Cucumber:

Just rub some cucumber slices on your face for 02-03 minutes to cleanse the oil naturally. Wash off with plain water.

* Buttermilk:

Apply all over your face and leave it to dry, then wash it with normal water (works for mixed to oily skin).

Face scrub for natural beauty

Take 01-02 strawberries, 02 pieces of kiwis or 02 cubes of watermelons. Mash any single fruit and apply on your face. Then massage or scrub it slowly for at least 3-5 minutes in circular motions. Then wash it thoroughly with normal or cold water. You can make use of different fruits during different seasons, and see what suits you best! Follow with a natural face mask.

Face Masks

* Papaya and Honey:

Take two pieces of papaya (peeled) and mash them to make a paste. Apply evenly on your face and leave it for 30 minutes and then wash it with cold water.

Papaya is just not a fruit but one of the best natural remedies for good health and glowing younger looking skin. It also helps in reducing pimples and scars. You can also add honey (optional) to the mixture which helps massage and makes your skin glow.

* Banana:

Put a few slices of banana, 01 teaspoon of honey (optional), in a bowl, and mash them nicely. Apply on your face, and massage it gently all over the face for at least 05 minutes. Then wash it off with normal water. For an instant glow on your face, this facemask is a great idea to try!

* Carrot:

Make a paste using 01 carrot (steamed) by mixing it with milk or honey and apply on your face and neck evenly. Let it dry for 15-20 minutes and then wash it with cold water. Carrots work really well for your skin as they have many vitamins and minerals, which give instant shine and younger-looking skin.
