We have chosen to create plug-in for CASE tool “Magic Draw UML”. This plug-in extends “Magic Draw UML” abilities of constraints creation, because system partially ensures the correctness of constraint elements. Plug-in was developed for system analysts, who precisely specify requirements for systems. The prototype we made successfully embodies main goals of project and can be improved in the future. Limited natural language templates can be specified using TBEProfile module. Business rules created with plug-in are formatted and clear to understand. It helps to improve project engineering level of automation. User using prototype is able to specify business rules in UML class, state protocol, state machine, sequence and activity diagrams. System was created using JAVA programming language and “Magic Draw UML OpenAPI”.

A ressonância magnética nuclear no domínio do tempo (RMN-DT), possui inúmeras vantagens em relação à RMN de alta resolução tais como: baixo custo do equipamento, de análise e manutenção e não precisa de operador especializado. Apesar disso a técnica de RMN-DT ainda tem um campo muito grande de desenvolvimento para análise de componente com baixa mobilidade molecular como sólidos amorfos e cristalinos. Isto requer o desenvolvimento de instrumentação e/ou métodos de análise que se consiga medir o sinal de RMN em menos de 10 µs, após a irradiação da amostra. O tempo entre o final da excitação e o começo da aquisição do sinal é conhecido como tempo morto. A opção estudada nesta dissertação para redução do tempo morto foi o uso de pulsos formatados, que já são utilizados em experimentos de RMN em alta resolução e de imagens por RMN, para excitação seletiva. No entanto, pulsos formatados não têm sido utilizados em RMN-DT. A principal vantagem desses pulsos é que eles são projetados para que a potência no final do pulso seja mínima, o que diminui o tempo morto do espectrômetro. No caso do pulso convencional, na forma retangular, a potência no final do pulso é máxima, o que aumenta o tempo morto. Os pulsos formatados utilizados foram pulsos Sinc, Sine e também pulsos com início similar aos pulsos retangulares, com potência máxima, e que depois de certo tempo tem decaimento similar aos pulsos Sinc e Sine. Esses pulsos inéditos foram denominados Reta-Sine e Reta-Sinc. Foram avaliados amostras heterogêneas (solido-líquido) e sólidas como CaSO4.2H2O, farelo de soja, polímeros amido e Policaprolactona. Esses pulsos também foram usados para monitorar reações de polimerização da resina epóxi com poliamida (Araldite®). Com esses métodos foi possível reduzir o tempo morto de espectrômetro de 23MHz 23 µs para 14 µs e de 20 Mhz de 9 para 6 µs. Com isso conclui-se que o pulsos formatados podem reduzir significativamente o tempo morto de espectrômetro de RMN-DT, sem acessórios ou custo financeiro, pois as sequências podem ser instalada e usadas em qualquer espectrômetro moderno. / The nuclear magnetic resonance in the time domain (TD-NMR) It has numerous advantages over the high-resolution NMR such as low cost of equipment, analysis and maintenance and requires no specialized operator. Nevertheless NMR DT technique also has a very large development field for component analysis with a low molecular mobility as amorphous and crystalline solids. This requires the development of instrumentation and / or analysis methods that can measure the NMR signal in less than 10 µs, after irradiation of the sample. The time between the end of excitation and signal acquisition the beginning is known as dead time. The option studied in this work to reduce the dead time was the use of formatted pulses, which are already used in NMR experiments in high resolution and NMR imaging for selective excitation. However, formatted pulses have not been used in NMR DT. The main advantage of these pulses is that they are designed so that the power in the pulse end is minimized, which reduces the dead time of the spectrometer. In the case of conventional pulse in rectangular form, the power in the pulse end is maximum, which increases the dead time. Formatted pulses used were Sync pulses, Sine and also pulses beginning similar to rectangular pulses with maximum power, and after a while has similar decay to Sync and Sine wrists. These unpublished wrists were called Sine and Straight-Line-Sync. They were evaluated heterogeneous samples (solid-liquid) and solid as CaSO4.2H2O, soybean meal, starch polymers and Polycaprolactone. These pulses are also used to monitor polymerization reactions the polyamide epoxy resin (Araldite®). With these sequences it was possible to reduce the dead time of 23 µs 23MHz spectrometer to 14 µs e 20 Mhz from 9 to 6 µs. With this it is concluded that the formatted pulses can significantly reduce the dead time DT-NMR spectrometer, without fittings or financial cost because the sequences can be installed and used in any modern spectrometer.

Οι κρατήρες διαφυγής ρευστών (pockmarks) είναι βυθίσματα σε μαλακά ιζήματα του βυθού, στα παράκτια και πελαγικά οικοσυστήματα. Μελετώνται παγκοσμίως τις τελευταίες τέσσερις δεκαετίες και στον ελληνικό χώρο έχουν εντοπιστεί κυρίως στη Δυτική Ελλάδα. Εξ αυτών, οι περισσότεροι είναι κρατήρες μεθανίου και μόνο στον Ελαιώνα Αιγίου και στον όρμο του Πρίνου έχουν βρεθεί κρατήρες γλυκού νερού. Έως τώρα, η μελέτη της βιολογίας των κρατήρων έχει εστιάσει κυρίως την περίπτωση των κρατήρων μεθανίου. Για τους κρατήρες γλυκού νερού δεν υπάρχουν εργασίες σχετικά με τη βιολογία τους, εκτός από μια η οποία αφορά τη μικροβιακή δράση στο ίζημα. Στον Ελαιώνα οπτική παρατήρηση έδειξε την ύπαρξη πληθώρας βενθικών οργανισμών, οι οποίοι απουσιάζουν από τον ευρύτερο πυθμένα. Το φαινόμενο αυτό έχει παρατηρηθεί σε πολλούς κρατήρες παγκοσμίως και θεωρείται ότι σχετίζεται κυρίως με τη φύση του υποστρώματος στο εσωτερικό της δομής των κρατήρων. Γενικά, υπάρχει πολύ περιορισμένη πληροφορία για το αβιοτικό και βιοτικό περιβάλλον των κρατήρων, ιδιαίτερα στη στήλη του νερού, ενώ δεν είναι σαφές το αν οι δομές αυτές μπορούν να αποτελέσουν διαταραγμένα περιβάλλοντα ή οάσεις οργανισμών. Η παρούσα εργασία διερευνά το πλαγκτικό στοιχείο στους κρατήρες γλυκού νερού του Ελαιώνα και αποτελεί την πρώτη σχετική αναφορά σε διεθνές επίπεδο, τουλάχιστον σε ότι σχετίζεται με το ζωοπλαγκτόν. Για τη μελέτη συλλέχθηκε μικρο- και μεσοζωοπλαγκτόν, έτσι ώστε να διερευνηθεί όλο το εύρος μεγέθους των οργανισμών από 50 μm έως 20 mm. Οι κρατήρες που μελετήθηκαν παρουσίασαν μικρή εκροή γλυκού νερού. Μετρήσεις θρεπτικών ιόντων και χλωροφύλλης -α έδειξαν ότι οι κρατήρες δεν επηρέασαν φυσικοχημικά το θαλάσσιο περιβάλλον. Ωστόσο, παρατηρήθηκε αύξηση της Chl-a κοντά στο στόμιο του κρατήρα και της φαιοφυτίνης (προϊόν αποδόμησης της Chl-a) και των θρεπτικών στο εσωτερικό του κρατήρα. Ως προς το ζωοπλαγκτόν, οι κρατήρες βρέθηκαν να συγκεντρώνουν μεγαλύτερες αφθονίες πελαγικών προνυμφών βενθικών οργανισμών που εγκαθίστανται στο εσωτερικό τους, όπως έχει επιβεβαιωθεί με οπτική παρατήρηση, καθώς και ειδών Αρπακτικοειδών και Ποικιλοστοματοειδών Κωπηπόδων (ενηλίκων, κωπηποδιτών, ναυπλίων). Τα εν λόγω κωπήποδα πιθανόν να σχετίζονται με την παρουσία αυξημένου αιωρούμενου οργανικού υλικού στους κρατήρες και ζελατινοειδών διηθηματοφάγων οργανισμών (κωπηλατών, βυτιοειδών) σε αυτούς. Επιπλέον, η αυξημένη συγκέντρωση ναυπλίων και κωπηποδιτικών σταδίων υποθέτουμε ότι μπορεί να σχετίζεται με την αυξημένη παρουσία αυγών κωπηπόδων, εφόσον η δομή του κρατήρα μπορεί να τα συγκεντρώνει. Επειδή η παρούσα μελέτη πραγματοποιήθηκε σε μια περίοδο ανάμιξης του νερού και μια περίοδο ασθενούς θερμοστρωμάτωσης, θεωρούμε ότι οι παρατηρήσεις μας για το ζωοπλαγκτόν δεν εμφανίζουν έντονο ‘’σήμα’’ και προτείνεται επανάληψη της έρευνας σε περίοδο έντονης θερμοστρωμάτωσης. / Pockmarks are seabed depressions on soft sediments, found in coastal and pelagic ecosystems. They have been studied for the last four decades and in Greece they can be found mainly in the western parts of the country. Most of the pockmarks are methane formatted, while groundwater formatted pockmarks have been found in Greece only in Elaionas bay and Prinos bay. So far, only methane pockmarks have been studied, concerning their biological components, and there are no references for the groundwater formatted ones, except one that focused on the microbial activity in the sediments. In Elaionas bay optical observations revealed the presence of an extensive benthic community that lacks from the surrounding seabed. This has been observed in a number of pockmarks worldwide and is believed to be co occurring with the presence of hard substrates in the pockmarks. Generally, there is little information of the biotic and abiotic environment of the pockmarks, especially in the water column, while it is not yet clear if these depressions should be considered as disturbed environments or local oasis for the organisms in the area. This study is focusing on the planktonic component of the pockmark field at Elaionas bay and to our knowledge it is the first attempt internationally, at least when it comes to zooplankton. Mesozooplankton and microzooplankton samples were collected in order to investigate the whole basic size range of the zooplankton community (50 μm to 20 mm). The studied pockmarks exhibited slight groundwater flow. Nutrient and chlorophyll a concentrations showed no physicochemical ‘’signal’’ in the pockmarks. However, there was a trend of increase of Chl –a near the opening of the pockmark and of phaeophytin and nutrients inside the pockmark. As for zooplankton, there is evidence that greater abundances of pelagic larvae of benthic organisms are concentrated in the pockmarks (the presence of the adults has been confirmed by divers and ROV), as well as some species of the Order Harpacticoida and Poecilostomatoida (adults, copepodites, nauplii). These copepods may be related to the increase of dissolved organic matter in the pockmark and the presence of tunicates (appendicularians, doliolids) also found concentrated in the pockmarks. Increased abundance of nauplii and copepodite stages in the pockmark is believed to result from the increase of copepod eggs, assuming that the pockmark can gather and retain them. Repetition of the sampling procedure at the pockmark field on a different season is necessary, because the lack of a strong thermocline suggests that any strong differences between the pockmark and the surrounding environment are being less detectible.

In this article, I seek to discuss the principles of modulation and variation in Deleuze’s canonical essay “Postscript on the Societies of Control” (Deleuze 1992). Analyzing and testing what Deleuze recognizes as “inseparable variations, forming a system of variable geometry” and as a “self-deforming cast that will continuously change from one moment to the other […], like a sieve whose mesh will transmute from point to point” (1992: 4), I will focus on the digital image
