Assessment of Seagoing Ships Longitudinal Strength in the Context of International Rules, Important Factor for Safe Operation  [PDF]
Dumitru Lupascu, Ionel Chirica
World Journal of Engineering and Technology (WJET) , 2015, DOI: 10.4236/wjet.2015.34029
Abstract: The paper is focused on the ship hull safety problems related to the longitudinal strength of the ship during design, construction and service in context of International Goal-Based Ship Construction Standards carried out by International Maritime Organization (IMO). The study underscores the importance of ship longitudinal strength for prevention of theirs losses, mentioning the most important measures taken by IMO for improvement of ship safety. In the work, a critical analysis of the methodology of the International Association of Classification Societies (IACS) for calculation of sectional efforts induced by waves in ship’s hull is described. Finally, a calculation base proposal for improvement the efforts on quasi-static layout of the ship on wave is performed.
Design Solutions for Jack up Platform Retrofitting  [PDF]

World Journal of Engineering and Technology (WJET) , 2015, DOI: 10.4236/wjet.2015.33015
Abstract: The paper is focused on the structural problems related to the retrofitting of a ship structure into a maritime self-elevating platform. The study is referred on the design of the global and local strengthening of the platform and legs structures. The joint structure built as the connection between the platform hull and the tubular legs, is designed so that to be acted by the special actuators. The total force provided by the actuators during the lifting operations is necessary to balance the total weight of the platform hull and operating equipment. The work described in the paper shows a methodology for FEM global and local strength calculation of platform structure and legs structure using site-specific parameters recommended by DNV rules, such as water depth, wave and wind loads. Also, the global static and dynamic behavior analysis of the jack up unit is presented. From the case study results it may conclude that the proposed methodology offers economic advantages to the field in which they are employed. In the paper, the platform structural capacity, incorporating yielding and buckling, is the limiting condition for the scenario under investigation.

Abstract: Early laparoscopic cholecystectomy within 5 days of onset of symptoms of acute cholecystitis has proved better to open cholecystectomy. Feasability is already well established; the conversion rate to open cholecystectomy and the post-operative morbidity are not higher than with the delayed laparoscopy after the initial medical management. Total hospital stay is, on the other hand, significantly shorter. Only one study showed an increase in operative time with early surgery (on average 15 minutes). Both preoperative or perioperative risk factors for conversion to laparotomy were identified. Prompt laparoscopic intervention avoids the complications which may arise with initial medical management, such as failure of medical management or biliary peritonitis. Early laparoscopic cholecistectomy should be considered the “gold standard” for management of acute cholecystitis.
Electoral Campaigns in the Process of Transition to Democracy in Romania after December 1989. Research Theme: Local Campaign for Mayor’s Office of Iasi, 2004 – The Construction of a Political Product
Revista Romaneasca pentru Educatie Multidimensionala , 2012,
Abstract: This study aims to present the electoral campaigns in Romania after December 1989. Electoral campaigns are designed, at least in theory, to inform voters about candidates and to help them better understand their position on problems of the moment, the causes for which they stand up for and party affiliations. Knowing the candidates and being aware of their conceptions and actions, the electors can decide who to vote for, whether to adjust or not their electoral options or if there is a need of changing the political power. Unfortunately, electoral campaigns succeed only partially to achieve these goals, failing most of the time to inform the electors and help them to vote according to them. The construction of the political figure, the notoriety of the candidate, the credibility, the slogan, the media agenda versus the population agenda, are matters of discussion absolutely necessary for a suitable analysis, and we cannot create an image of coherency in the planning of a campaign or, even more specific, in the construction of a political product. After the first part, which is to some extent theoretical, in the second part I will put forward a practical study which in this case can only be the presentation of a fragment of electoral campaign. It is a fragment because the amplitude and complexity of approaching an electoral campaign with all of its elements would overcome the time allocated during this conference, this is the reason why I will analyze the electoral campaign through the construction of the political product. The research’s presentation consists of the local campaign for the Mayor’s office of Iasi, in 2004, considered through the national electoral context: the realization of the D.A. alliance between PNL and PD in the autumn of 2003, meant the beginning of the actual electoral struggle in Romania. If when the alliance was launched, in the autumn of 2002, the two parties were almost alike, around 10-12%, after one year, PNL rose to 18-20% and PD remained at 10-12%. In order to have a clearer image upon the political market” of Iasi I have presented the first five brands” (political parties) with their the political products” (candidates for the position of Mayor) resulted from this campaign and, bearing in mind the criteria announced above, I found interesting the evolution of two candidates for the seat of Mayor of Iasi: Dan Carlan- Democrat Party (PD) and Relu Fenechiu- National Liberal Party (PNL). Finally, I was concerned with the construction of the political product of PD and PNL, and moreover, the logical conclusions of the scien
The 2008 Election Moment. Iasi, the First Uninominal Elections
Revista Romaneasca pentru Educatie Multidimensionala , 2012,
Abstract: In this article we try to present and briefly analyze the local and the parliamentary elections from 2008 in Iasi County. Through this paper we intend to reveal the voters’ expectations in terms of electoral offer, and also the desirable dominant traits of the candidates proposed by the main political parties, through the choices at the polls.The results of these elections have revealed two contradictory features in the options of the electorate: at the local level, we can clearly see a trend of preserving local structures, voters going for the incumbent candidate for the seat of the Mayor and for the County Council they voted for a well- known person, with the highest degree of notoriety, certified by two terms as Mayor of Iasi; while in the general elections, a renewal trend of the Romanian Parliament, long waited as a renewal of the entire political class, was clearly seen.

Abstract: The matrimonial regime is ruled by two perspectives, the Roman law and the German one. The Romanian concepts were taken from the French law. The new Romanian Civil Code is characterized by the special attention it pays to the regulation of spouses' patrimonial relationships, ant it therefore abandons the exclusivist conception and enacts several matrimonial regimes, namely: a) the regime of legal community; b) the regime of separation of assets; c) the regime of separation of assets with participation to acquisitions; d) the regime of conventional community. The matrimonial convention represents the legal document by which future spouses, or, as the case may be, current spouses, resorting to the liberty they have been conferred by the legislator, determine their own matrimonial regime or, as the case may be, modify their applicable matrimonial regime.

Abstract: A review of the literature describing the hepatic and splenic blunt trauma, indicates that as many as 67% of exploratory celiotomies, are reports as diagnostic. Avoiding unnecessary surgical procedure offers an attractive choice. Nevertheless, nonsurgical management should not bew considered unless the patient meets the following criteria: 1) hemodynamic stability, with or without minimal fluid resuscitation; 2) no demonstrable peritoneal signs on abdominal examination; and 3) the absence on computer tomography (CT scan) of any intraperitoneal or retroperitoneal injuries that require operative intervention. Although a patient could meet the above criteria, several additional factors can be used as predictors of failure of non surgical treatment.

Abstract: Endoluminal surgery of the varicose veins it's not a recent technique but the new procedures using radiofrequency and laser considerably relaunced its interest. The thermic energy that this technique gives to the venous wall induces a fibrous retraction of the vein and its occlusion. There are detailed here the material needed, methods but also the difficulties, possible incidents and accidents during them. The indications of these endoluminal interventions are still a disputed subject. The evaluation of the results is difficult, especially for laser procedures because the materials and techniques are various and the methods are not standardized.
