Součástí je i předběžný návod k použití.This Bachelor´s thesis is concerned with the construction of floating skimmers which enable the collection of crude oil-based materials or similar materials and their pumping-off - including similar such materials by pumps located on the banks (of rivers, etc,) into pre-prepared containers. Its components include the theoretical introduction as well as research into similar products in the world. It resolves the calculations of the floatqualities of skimmers, and linked to that, the suggested design of the whole construction enables one to automatically regulate at a distance the thickness of the pumped-off layers. A complete 3D model has been created for the control of components with the aid of FEM analyses, the creation of the underpinning documentation as well as photo-realistic visualistaions.

BUGARSKA NA PUTU KA EVROPSKOJ UNIJI – O IZMENI BUGARSKOG USTAVA OD 24. SEPTEMBRA 2003.

Taking into consideration the continuous complaints for corruption, organised crime and „the existence of the state not based on law“ the EU Commission required additional reforms of judiciary (transparency, openness, rendering of an accounting). Therefore, Sofa – being concerned that Brussels could stipulate the Bulgarian accession to EU by applying the so-called protection clauses – rapidly took on to carry out the Constitution reform. Actually, for twelve years the Constitution of the Republic of Bulgaria had remained “untouchable” for the fear that it could provoke serious reactions due to different positions on the reform. However, after the European Commission had criticised “the state of the Bulgarian judiciary” and since the accession to NATO was soon to come, there was no other choice. Therefore, it adopted amendments in the following sequence: the first amendment – on 23 February 2003, the second amendment – on 25 February 2005 and the third amendment – on 30 March 2006. The immediate cause for the adoption of the fourth constitutional amendment was, among other things, the Article 129, paragraph 4, which had been introduced by the third reform of 30 March 2006. The European Commission realised that the division of power was jeopardised, what also affected the independence of the judiciary. This was because the President of the state was authorised by the parliament to dismiss three supreme magistrates (the President of the Supreme Court of Cassation, the President of the Supreme Constitutional Court as well as the General State Prosecutor) in the case related to the Article 128 paragraph 4 point 5. As early as on 2 February 2007 the Assembly adopted the fourth amendment to the Constitution of the Republic of Bulgaria with 129 votes for, 28 against (with 6 abstentions), thus fulfilling some requests of the European Commission. As during the consultations on the new Law on Constitutional Court the parliament requested to make amendments that would “additionally change the Constitution” the fifth amendment is likely be adopted afterwards.Bugarska, kao zemlja koja pretenduje da bude članica EU, mora da zadovolji dva osnovna kriterijuma iz Mastrihta: demokratski sistem vlasti i poštovanje ljudskih prava. U tom sklopu, i specifčne kriterijume, precizirane na Evropskom savetu u Kopenhagenu 1993. godine, između ostalih: stabilnost institucija kojima se garantuju demokratija, pravna država, ljudska prava i poštovanje i zaštita manjina.1 Uprkos izmeni bugarskog Ustava od 24. septembra 2003. godine, Bugarskoj stižu nova upozorenja od Evropske komisije. Rukovodilac pregovaračke ekipe EU sa Bugarskom Bridžet Černota ističe da “Bugarska previše kasni u reformi sudstva, promenama u zakonodavstvu: davno su istekli rokovi kada je parlament te zemlje trebalo da donese zakone o zaštiti potrošača i konkurencije, o onemogućavanju diskriminacije građana iz Evropske unije koji počinju biznis u Bugarskoj i neke druge”. Otuda, EU – predočila je Černota – iz tih. razloga, može da primeni zaštitne klauzule i odloži prijem Bugarske u EU, predviđen za 1. januar 2007. godine

Anthropometric Indices of Obesity and Potential Health Risk in Adult Rural Population from Bačka and Banat – The Republic of Serbia

Obesity, along with other unhealthy living habits, nowadays represents one of the greatest risk factors for various diseases. Vojvodina is a part of Serbia where a high percentage of the overweight has been recorded since the period of former Yugoslavia. The aim of this study therefore was to determine the percentage of adults with potential health risk using the indices of obesity. The anthropological study was conducted from 2001 to 2006. The tested group consisted of 4504 individuals, 1965 men and 2539 women. The mean age of the sample was 40.61±11.29. The data were collected in 46 villages in Bačka and Banat, in the central and north-east parts of Vojvodina, situated in the north of Serbia. The investigation included the height, weight, waist and hip circumference. Nutritional condition was determined using the body mass index (BMI kg/m2), while the waist circumference and WHR were used for assessing the central obesity. According to the average BMI (26.86 kg/m2 males, 25.80 kg/m2 females), the population of Bačka and Banat is characterised with pre-obesity. In total, 58.47% individuals of both sexes are with excessive body weight, 38.52% of them being classified as overweight and 19.48% as obese. Central obesity is more frequent in males aged up to 40, while in females it is more present above the age of 50. A higher waist circumference (males≥94 cm; females≥80 cm) is observed in 58% of males and 55% of females, with the risk value (males≥102 cm; females≥88 cm) recorded in 32% of men and women. The indices of obesity indicate a potential health risk for more than a half of the subjects in this study. The data therefore point to the necessity of introducing educational programs for promoting good nutrition and healthy living habits that would ultimately reduce the number of individuals with health risk

Personajele feminine in romanele interbelice ale lui Camil Petrescu

Svrha ovog rada prikazati je odabrane ženske likove u međuratnim romanima Camila Petrescua. Riječ je o romanima Posljednja noć ljubavi, prva noć rata te Prokustova postelja iz kojih sam izdvojila i analizirala likove Ele, Emilie te gospođe T. Kako bih analizirala odabrane ženske likove, bilo je potrebno spomenuti i kako je izgledalo međuratno razdoblje u rumunjskoj književnosti te biografiju Camila Petrescua kao i događaje koji su utjecali na stvaranje ženskih likova u njegovim djelima. Svaki je ženski lik zasebno opisan unutar poglavlja koja se odnose na romane i njihovu radnju bez koje bi bilo nemoguće analizirati ženske likove. Pri analizi tih likova u obzir sam uzela i vrijeme u kojem su napisani navedeni romani te ulogu žene u međuratnom razdoblju i na početku 20. stoljeća kao i navodnu autorovu mizoginiju koja se ipak ponekad može primijetiti u opisima i karakterizaciji ženskih likova. Lik Ele iz romana Posljednja noć ljubavi, prva noć rata prvi je analiziran ženski lik. Riječ je o liku kojeg upoznajemo isključivo kroz oči njezinog supruga te o njoj stvaramo mišljenje od subjektivnih dojmova koje nam prenosi njezin suprug koji je ujedno i pripovjedač. Analiza Ele dovodi do zaključka kako se njezin karakter mijenja kako se mijenja način na koji je vidi njezin suprug. Činjenica jest da je na čitateljima da zaključe kakva je prava Ela uz pomoć dojmova njezinog supruga, no i objektivnim pogledom na situacije koje nam donosi pripovjedač. Emilia iz romana Prokustova postelja predstavlja vulgarnu i prilično neinteligentnu ženu koja ciljeve postiže uz pomoć veza s brojnim muškarcima iz visokog društva Bukurešta. Ona je glumica u usponu koja se pokušava proslaviti uz pomoć veza s redateljima i utjecajnim muškarcima. Mogli bismo reći da je Emilia negativan lik, smatram da u modernom romanu nema mjesta za crno-bijelu klasifikaciju likova na pozitivne i negativne. Preostaje još gospođa T., najsloženiji ženski lik u romanu Prokustova postelja. Gospođa T. predstavlja modernu i emancipiranu ženu koja je drukčija od ostalih ženskih likova. Ona je inteligentna i jaka, ona je žena koja se može nositi s Petrescuovim muškim likovima koji su neshvaćeni intelektualci. Gospođa T. predstavlja promjene u modernom društvu međuratnog razdoblja i početak ženske emancipacije
