Abstract: Trends in sustainable development of tourism in Romania. This study focuses on a thorough analysis of tourism in Romania, by underlining the issues that support the prerequisites of sustainable development concept. Firstly, we highlight the management and planning patterns of thermal and mineral water in the current health resorts, where hidrographical resources have been used for centuries and have not yet been exhausted. The tourist potential of the Romanian Carpathians and the Black Sea has enabled the development of various forms of tourism and tourist infrastructure suitable for both primary and derived offer. Romania’s integration into the European Union, as well as its complying with the regulations of market economy have led to establishing a new globalized tourism, based on sustainable development, regarding mainly the cultural and rural tourism.
Tourism and Archaeology: Back to Origins

Journal of Settlements and Spatial Planning , 2011,
Abstract: Archaeological tourism is an alternative form of cultural tourism, which aims to promote the passion for history and the preservation of historical sites. Unfortunately, today, in Romania, there is not a real connection between archaeology and tourism and there are only few sites exploited for tourism. The interests between archaeology and tourism due to the preservation and the capitalization of the historical remains, generates, in fact a sustainable form of tourism. From this point of view the attractiveness of the sites is based on the idea of preserving the “spirit of place” by safeguarding of tangible and intangible heritage. This is the most important in capitalizing the Romanian rural space, too. A fascinating subject related to archaeological tourism is Roman archaeological remains. In this paper we will make a classification of some roman archaeological sites by the level of importance for tourism. This sites are all situated in rural area: the milestone from the Roman period situated in Aiton Village, the rural settlement from the Roman era, the aqueduct and the Roman road from Cop ceni and the Roman camp, the Roman road, the temples and the possibility for a touristic site museum from Tibiscum . Finally, the paper will consider three sites near Cluj-Napoca: Dealul Lomb (a Roman villa), Polus Centre area (the remains preserved in situ) and the S ndule ti settlement (Roman remains, near the spring of Cop ceni which was captured in the Roman era, too).
ROBOTIC ASSISTED LAPAROSCOPIC MYOMECTOMY VERSUS CLASSICAL MYOMECTOMY - A COMPARATIVE STUDY
Sidonia Maria S?ceanu,V. ?urlin,Cristina Angelescu,?t.Ptracu
Jurnalul de Chirurgie , 2012,
Abstract: AIM:The objective of this study was to perform a comparative analysis between robotic assisted laparoscopic and open approach, for patients with uterine leiomyoma, in terms of feasibility and quality of operation (duration of surgery, number and dimensions of extracted miomas, intraoperative blood loss). MATERIAL AND METHODS: We conducted a retrospective study on 166 patients diagnosed with uterine fibroids who have received conservative surgery – myomectomy over a period of 3 years (2008-2010). 38 cases were treated by robotic assisted laparoscopic myomectomy (RALM) and 128 patients underwent open myomectomy. RESULTS: BMI was higher among patients with RALM, 27.68 vs 22.63, respectively. The average time of interventions was similar, 111.8 min for RALM. Time for myomectomy itself was 50.39 min and 22.37 min for the uterine suture. Open myomectomy took an average of 103 min, 21.05 min for myomectomies itself, and 21.05 min for the uterine suture. In RALM, a higher number of myomas were extracted, but with a smaller volume, 2.26 myomas with a volume of 57 mm3 vs 1.8 myomas with a volume of 156 mm3 for open myomectomy. Blood loss was significantly lower during robotic-assisted laparoscopic myomectomy compared to open myomectomy, 140 mL vs 267 mL. Patients treated by RALM had a shorter length of stay 2.05 versus 6 days. Postoperative complications in RALM were insignificant. In open miomectomy we noted: a case of uncontrollable intraoperative bleeding that required the use the Gelaspon, 4 cases of postoperative febrile syndrome and one case of urinary infection. CONCLUSIONS: RALM is feasible and allows superior results compared to open myomectomy, with less blood loss and shorter postoperative hospital stay.
Scientists Deduced the Existence of Particles with Faster-than-Light Speeds Recently Discovered by CERN

MARKER ASSISTED SELECTION OF VENTURIA INAEQUALIS FUNGUS ON DIFFERENT GENOTYPES OF APPLE
Bianca Ionela Ptracu
Fruit Growing Research , 2012,
Abstract: Apple scab caused by Venturia inaequalis, is an important disease, spread worldwide, having a major negative impact in apple production. In this study, there were analyzed four apple cultivars (Liberty, Florina, Starkrimson, Golden Spur), used as genitors in a diallel cross, and their seedlings. In the field, plants selection was done after presence or absence of the scab on leaves, and afterwards, phenotipically selection was completed by marker assisted selection. The molecular analysis conducted with the markers AL-07, AM-19 and U1400, detects the presence of the Vf gene, introgressed from Malus floribunda 821, which confers resistance to the pathogen, in the parental cultivars Liberty and Florina, and in all the F1 hybrids belonging these two genitors. Starkrimson and Golden Spur were susceptible scab parents with recessive homozygous genotype (vfvf), while Liberty and Florina were identified as heterozygous scab resistant parents with genotype (Vfvf). From the 60 apple seedlings analyzed, grouped in six combinations after their genitors (in each combinations were selected ten hybrids, among them five resistant and five susceptible to apple scab attack) 28 were resistant and heterozygous for Vf gene (Vfvf) and 32 were susceptible to scab with recessive homozygous genotypes (vfvf), being obtained almost Mendelian ratio for response to the pathogen, 50% resistant: 50% susceptible. Seedlings belonging to Starkrimson x Golden Spur were only recessive homozygous genotype (vfvf), and in combination resistant x resistant (Liberty x Florina) were identified susceptible and resistant offspring, but at last, only with heterozygous for Vf gene (Vfvf) and no one with dominant homozygous genotypes (VfVf). Classical methods of selection, regarding apple scab resistance can be very much improved using genetics markers sent in linkage with important phenotypics characters, could become a technics in shorting selection process by reduction of time and of breeding programme costs.
Using Hashing to Solve the Dictionary Problem (In External Memory)
John Iacono,Mihai Pǎtracu
Computer Science , 2011,
Abstract: We consider the dictionary problem in external memory and improve the update time of the well-known buffer tree by roughly a logarithmic factor. For any \lambda >= max {lg lg n, log_{M/B} (n/B)}, we can support updates in time O(\lambda / B) and queries in sublogarithmic time, O(log_\lambda n). We also present a lower bound in the cell-probe model showing that our data structure is optimal. In the RAM, hash tables have been used to solve the dictionary problem faster than binary search for more than half a century. By contrast, our data structure is the first to beat the comparison barrier in external memory. Ours is also the first data structure to depart convincingly from the indivisibility paradigm.
LOCALLY ADVANCED OR METASTATIC GASTRIC CANCER – AN EPIDEMIOLOGICAL AND DIAGNOSING UPDATE
Florina Ptracu,Adina Croitoru,Iulia Gramaticu,M. Andrei
Jurnalul de Chirurgie , 2011,
Abstract: Gastric cancer represents a major health problem worldwide. It is often diagnosed at an advanced stage, because screening, which would help an early detection is performed only in Japan. Gastric cancer rates may be decreased by reducing smoking and alcohol consumption and by increasing the number of fresh fruits and vegetables eaten. Eradication of Helicobacter pylori may also decrease gastric cancer incidence. Seventy-five percent of the patients are diagnosed in unresectable stage. They represent a challenge for clinicians as they have to choose between a strictly supportive approach or to expose patients to the side-effects of a potentially ineffective treatment. The treatment of advanced gastric cancer is essentially palliative.
THERAPEUTIC APPROACHES IN ADVANCED BILIARY TRACT CANCER – EXPERIENCE OF FUNDENI DIGESTIVE ONCOLOGY DEPARTMENT

Jurnalul de Chirurgie , 2011,
Abstract: Cholangiocarcinoma is a rare malignancy, difficult to diagnose, associated with a high mortality. Diagnosis and treatment of these tumors are complex and require a multidisciplinary team. The prognosis is infaust, about 80% of patients being in unresectable stage at the moment of diagnosis. The incidence of intrahepatic cholangiocarcinoma is increasing worldwide, not very well explained, probably by improving diagnostic methods. A complete surgical resection with histologically negative resection margins is the only cure for cholangiocarcinoma, the results depending on technique used and the careful selection of patients. Chemotherapy, radiotherapy and biliary drainage are palliative methods of treatment. Liver transplantation for unresectable cholangiocarcinoma is currently contraindicated because of a high recurrence rate. Photodynamic treatment might improve quality of life. In the following, we will describe the results of a retrospective study which took place during the period 06.01.2004 – 01.01.2005, in the Department of Digestive Oncology - Fundeni Clinical Institute, including the patients with locally advanced and metastatic cholangiocarcinoma, treated by systemic chemotherapy. The results were compared with a similar study from our department during 2002-2003.
Finding the Median (Obliviously) with Bounded Space
Paul Beame,Vincent Liew,Mihai Pǎtracu
Computer Science , 2015,
Abstract: We prove that any oblivious algorithm using space $S$ to find the median of a list of $n$ integers from $\{1,...,2n\}$ requires time $\Omega(n \log\log_S n)$. This bound also applies to the problem of determining whether the median is odd or even. It is nearly optimal since Chan, following Munro and Raman, has shown that there is a (randomized) selection algorithm using only $s$ registers, each of which can store an input value or $O(\log n)$-bit counter, that makes only $O(\log\log_s n)$ passes over the input. The bound also implies a size lower bound for read-once branching programs computing the low order bit of the median and implies the analog of $P \ne NP \cap coNP$ for length $o(n \log\log n)$ oblivious branching programs.
