The radiation released by Hiroshima bone has marked human bones

On Aug. 6, 1945, the United States dropped an atomic bomb nicknamed “Little Boy” on Hiroshima, Japan, leading to a nuclear blast that instantly claimed about 45,000 lives. Now, the jawbone of one of those casualties — belonging to a person who was less than a mile from the bomb’s hypocenter — is helping researchers determine how much radiation was absorbed by the bones of the victims, a new study finds.

The amount is staggering: Analyses show that the jawbone’s radiation dose was about 9.46 grays (Gy). A Gy is the absorption of one joule of radiation energy per kilogram of matter, which in this case is bone.

QS rankings 2018 and the UoA Physics Department

The QS World University rankings for 2018 were announced very recently. It is always interesting to see some of the data regarding overall performance and assessment by the QS foundation. The latter uses their own algorithm and set of criteria to manage available bibliographical data (in collaboration with Elsevier as I read), thus producing a ranking list for several hundreds of universities around the World.

Regarding Physics I am interested in, our National and Kapodistrian University of Athens Physics Department is placed in positions 401-500, maintaining its status in the top-500 universities of the world. However, according to the QS criteria, UoA Physics is placed in the last position among Greek Physics Departments. See results and a screenshot below:

Putting aside the fact that NTUA (ranked in 151-200) is not a pure Physics Department, AUTh occupies the second place, while U.Crete is in No3.

Amid non-existent research funding, personnel reduction to a 40% with respect to what it was 3-4 years ago, turbulence with new legislation and “reforms”

I am personally very happy that NTUA Physics is still in the top-500. A different ranking based on another set of criteria (excluding from points the number of foreign students and faculty, mutlilingual programs, international character etc) has put the Physics Dept of UoA in the 101-150 worldwide for 2016 and 76-100 in 2017. Not bad for what we, as faculty, experience in our miserable everyday lifes.

Προσωρινοί πίνακες κατάταξης ΕΛΙΔΕΚ – Μεταδιδάκτορες

Μόλις πριν λίγο αναρτήθηκαν οι προσωρινοί πίνακες κατάταξης για τη δράση ΕΛΙΔΕΚ “ενίσχυση μεταδιδακτόρων”. Για τις φυσικές επιστήμες, υπάρχει το όριο των 24 προτάσεων προς χρηματοδότηση, το οποίο αντιστοιχεί σε βαθμολογία 84.

Έγκριση Προσωρινών Πινάκων Κατάταξης για επτά (7) Επιστημονικές Περιοχές, στο πλαίσιο της 1ης Προκήρυξης ερευνητικών έργων ΕΛΙΔΕΚ για την ενίσχυση Μεταδιδακτόρων Ερευνητών/τριών

Στην Πυρηνική Φυσική (βασική ή εφαρμογές) δεν υπάρχει καμία που να ξεπερνά το όριο αυτό, νομίζω 75 είναι η πιο υψηλή που βρίσκεται. Εξαιρετικά ανησυχητικό για το μέλλον του πεδίου, καθώς οι μεταδιδάκτορες πρέπει να ενισχυθούν για να είναι έτοιμοι να αποτελέσουν την επόμενη γενιά μελών ΔΕΠ στο αντικείμενο. Χωρίς εμπειρία δεν υπάρχει περίπτωση να συνεχίσουν προς αυτήν την κατεύθυνση.

Βραβεία Ακαδημίας Αθηνών 2017

Συνηθίζω να αφιερώνω λίγο χρόνο στην παράθεση των δεικτών των εργασιών που βραβεύονται από την Ακαδημία Αθηνών, με έμφαση στις Θετικές Επιστήμες και στις Επιστήμες Μηχανικών. Το βλέπω λίγο σαν παιχνίδι, αλλά έχει και κάποιο ενδιαφέρον σχετικά με τη διαδικασία της αξιολόγησης, και ίσως για κάποιους, με το επίπεδο των ίδιων των εργασιών που συμμετέχουν και τελικά βραβεύνται.

Ειδικότερα φέτος, αναλυτικά τα αποτελέσματα έχουν ανακοινωθεί εδώ.

Για τα βραβεία που έχουν αποδοθεί σε δημοσιευμένες εργασίες (υπάρχουν και κάποιες για συνολική προσφορά, ακαδημαϊκές επιδόσεις κτλ, αναλυτικά τα κριτήρια και οι θεματικές περιοχές των βραβείων για το 2017 εδώ), παραθέτω τον παρακάτω πίνακα, με τα σχόλια δικά σας.

Getting ready for HNPS2017

It’s been a while since my last blog post. I have been really busy with end of the semester and preparing for a couple of Conferences where our group are participating.

The first one is coming up this weekend, Friday and Saturday 9-10.06.2017. It is the 26th Annual Symposium of our Hellenic Nuclear Physics Society, our little body of nuke people who gather together, present their recent works and give lots of space to young researchers to immense in what is going on in our field.

This year we have prepared an impressive number of 7 posters and 1 oral talk spanning all aspects of our scientific activities. The NuSTRAP group are active in three main directions, namely nuclear structure, nuclear reactions and applications of radiation including instrumentation and environmental studies. Despite being mostly preliminary, our results are publicly available online. You can visit this page to view our recent posters and if you fancy, give us some feedback or publicize our work to the social media. I stress out the fact that the majority of the work has been carried out by undergrads who spend a lot of time and showed exceptional eagerness to advance science while getting educated.

We will be standing next to our posters this coming Friday and Saturday, here is a link to the official program of HNPS2017. This is the list of posters:

Nuclear Data 2016 – Bruges

For a nuclear structure experimentalist, it might not be worth attending a big Conference, such as Nuclear Data 2016, which is dominated by nuclear reactions and an infinite number of cross-section measurements of all kinds (it’s not an exaggeration to say 80% is neutrons on uranium). Nevertheless, the limited sessions dedicated to data regarding nuclear structure had its own value: meet bureaucrats, higher-rank officials and database managers that are at the core of information dissemination and data evaluation. For all it’s worth, ND2016 was an interesting International Conference of ~500-600 participants held in a magic city: Bruges (Brugge for the locals).

Never been in Bruges before, but it surely had a large impression on me. First, the weather for Belgian standards was excellent. Sunshine, dry atmosphere, 28C for a full week and very few clouds just for a morning. Easy to walk or ride your bike, Bruges is UNESCO Heritage City, preserving the local architecture style today, which except some large buildings (cathedrals, palaces, some old factories) imitates the gothic style that makes her distinct.

The Conference did not offer any lunch or dinner, except a ceremonial one the night before the last day in the beautiful Belfort located in central Market, so it was a good opportunity to explore the city during the noon breaks and nights. Even the most fanatic anti-alcohol could not resist the charm of the highest number of beer labels offered in the pubs. Try Beerwall next time you be there and you will get amazed.

If you are not visiting for a conference or a football game (place was flooded by Leicester fans on Wednesday due to a Champions League match) Bruges is a place for a romantic weekend. You have all the comfort in time to visit all major attractions, visit monuments, cathedrals, bridges crossing the streams. You can admire the beautiful swans swimming in the waters and enjoy good food and beer. On the expensive side, especially if you are staying inside the old city (Oud Brugge), the city is simply great for a short visit.

I hear that the next Nuclear Data (ND2019) will be held in Beijing, but INPC2019 will take place in Edinburgh. So, dear students of the NuSTRAP group, put some extra effort and we could have nice works to present in Scotland in three years!
