“In an increasingly large amount of scientific literature, DA-HAIs are considered the principal threat to patient safety in the ICU and are among the main causes of patient morbidity and mortality [1] and [2]. In industrialized countries, device-associated healthcare-associated infection (DA-HAI) surveillance in the intensive care unit (ICU) plays a substantial role in hospital infection control and quality assurance [3] and was reported by the Centers for Disease Control

and Prevention (CDC) study of the efficacy of nosocomial Regorafenib molecular weight infection control (SENIC) as an efficacious tool to reduce DA-HAIs [4]. The CDC’s previous National Nosocomial Infection Surveillance System (NNIS) and current National Healthcare Safety Network (NHSN) have established standardized criteria for DA-HAI surveillance [5] and [6]. This standardized surveillance method allows for the determination of DA-HAI rates per 1000 device-days, which can be used as benchmarks

among healthcare centers, and provides infection control practitioners (ICPs) with an in-depth look at the institutional problems they are confronted with so they can design an effective strategy to solve them. However, in the context of an expanded framework for DA-HAI control, most of the relevant studies of ICU-acquired infections have been carried out filipin in industrialized countries [7]. In developing countries, in contrast, few published studies have reported DA-HAI rates using standardized definitions [8], [9], [10], [11], [12], [13], [14] and [15]. The International Nosocomial Infection Control Consortium (INICC) was founded in 1998, when selected hospitals from Latin America were invited to participate in the project to measure DA-HAIs using standardized definitions and methodology [16]. Subsequently, other hospitals from different parts of the world joined the INICC. Currently, the INICC comprises a worldwide network of 300 hospitals from 40 countries in Latin America, Asia, Africa and Europe [12]. On a monthly basis, healthcare facilities send data to the INICC, which are then entered into an international database.

Zastosowanie każdego środka przymusu bezpośredniego podlega odnotowaniu w indywidualnej i zbiorczej dokumentacji medycznej. Stosowanie środków przymusu bezpośredniego wobec dzieci w placówkach psychiatrycznych nie budzi wątpliwości. Wątpliwości

mogą powstać jedynie co do określenia, czy zachowanie pacjenta wyczerpuje podstawy jego zastosowania. Problem dotyczy stosowania środków przymusu bezpośredniego w innych niż szpitale psychiatryczne podmiotach leczniczych. W tym miejscu warto zaznaczyć, że określenie „szpital psychiatryczny” odnosi się również do oddziału psychiatrycznego w szpitalu ogólnym, kliniki psychiatrycznej, sanatorium dla osób z zaburzeniami psychicznymi, selleck products innego podmiotu leczniczego sprawującego całodobową opiekę psychiatryczną lub odwykową (art. 3 pkt. 2 Ustawy o ochronie zdrowia psychicznego). Ustawa o ochronie zdrowia psychicznego pomija kwestię stosowania środków przymusu bezpośredniego wobec pacjentów

w innych podmiotach leczniczych. W tej materii powstaje pytanie, czy są podstawy prawne do stosowania środków przymusu bezpośredniego, określonych w Ustawie o ochronie zdrowia psychicznego, wobec pacjentów małoletnich, którzy na skutek zaburzeń somatycznych znajdują się w stanie psychicznym uniemożliwiającym skuteczne leczenie czy też bezpieczny pobyt w szpitalu. I zaznaczamy, że nie chodzi tu o przeprowadzenie procesu diagnostyczno-terapeutycznego bez zgody przedstawiciela ustawowego, ale o zastosowanie przymusu bezpośredniego, np. w postaci unieruchomienia, gdy zaburzenia psychiczne małoletniego pacjenta polegające na nadpobudliwości Volasertib clinical trial psychoruchowej są następstwem np. zapalenia opon mózgowych czy choroby zakaźnej połączonej z drgawkami i wysokimi temperaturami. Nie zawsze bowiem z takimi dziećmi przebywają na oddziale rodzice

czy inni opiekunowie. W tego typu sytuacjach personel medyczny ma do czynienia z pacjentami wykazującymi zaburzenia psychiczne o podłożu somatycznym, które powodują, że pacjenci stanowią zagrożenie dla samych siebie. W tej sytuacji może powstać potrzeba przeciwdziałania. I powracamy do postawionego pytania, czy są podstawy prawne takiej interwencji, a jeżeli tak, to jakie są jej granice [3]. W literaturze prawniczej wskazuje się na dopuszczalność zastosowania środków Fossariinae przymusu bezpośredniego wobec pacjenta z zaburzeniami psychicznymi przebywającego w innym szpitalu aniżeli psychiatryczny. Chodzi tu bowiem o zagwarantowanie pacjentowi bezpieczeństwa [3], [9], [12] and [18]. Warto w tym miejscu pokrótce prześledzić przedstawiane w tej mierze argumenty. Po pierwsze można rozważyć stosowanie art. 18 Ustawy o ochronie zdrowia psychicznego, pozwalającego na zastosowanie środka przymusu bezpośredniego wobec pacjenta z zaburzeniami psychicznymi, jeżeli pacjent ten dopuszcza się zamachu przeciwko życiu lub zdrowiu własnemu.

The surprisal   (or ‘self information’) of

the outcome of a random variable is defined as the negative logarithm of the outcome’s probability, which in this case is the probability of the actual next word wt+1wt+1 given the sentence so far: equation(1) surprisal(wt+1)=-logP(wt+1|w1…t),where the base of the logarithm forms an arbitrary scaling factor (we use base-e). Informally, the surprisal of a word can be viewed as a measure of the extent to which its occurrence was unexpected. The symbols w in Eq. (1) do not need to stand for actual words. Instead, they may represent the words’ syntactic categories (i.e., their parts-of-speech; PoS), in which case Eq. (1) formalizes the unexpectedness of the encountered PoS selleckchem given the PoS-sequence corresponding to the sentence so far. This does away with any (lexical) semantics and may thereby reveal purely syntactic effects (cf. Frank & Bod, 2011). Several authors have put forth theoretical arguments for surprisal as a measure of cognitive processing effort or predictor of word reading time (Hale, 2001, Levy, 2008, Smith and Levy, 2008 and Smith and Levy, 2013) and it is indeed well established by now that reading times correlate positively with the surprisal of words (Fernandez Monsalve et al., 2012, Fossum and Levy, click here 2012, Frank, 2014, Frank and Thompson, 2012, Mitchell et al., 2010,

Roark et al., 2009 and Smith and Levy, 2013) as well as with the surprisal of parts-of-speech (Boston et al., 2008, Boston et al., 2011, Demberg and Keller, 2008 and Frank and Bod, 2011). A second important concept from information theory is entropy   ( Shannon, 1948), a measure of the uncertainty about the outcome of a random variable. For example, after

processing w1…tw1…t, the uncertainty about the remainder of the sentence is quantified by the entropy of the distribution of probabilities over the possible continuations wt+1…kwt+1…k (with k>tk>t). This entropy Pyruvate dehydrogenase is defined as equation(2) H(Wt+1…k)=-∑wt+1…kP(wt+1…k|w1…t)logP(wt+1…k|w1…t),where Wt+1…kWt+1…k is a random variable with the particular sentence continuations wt+1…kwt+1…k as its possible outcomes. When the next word or part-of-speech, wt+1wt+1, is encountered, this will usually decrease the uncertainty about the rest of the sentence, that is, H(Wt+2…k)H(Wt+2…k) is generally smaller than H(Wt+1…k)H(Wt+1…k). The difference between the two is the entropy reduction  , which will be denoted ΔHΔH. Entropy is strongly reduced when moving from a situation in which there exists many possible, low-probability continuations to one in which there are few, high-probability continuations. Informally, entropy reduction can be said to quantify how much ambiguity is resolved by the current word or PoS, at least, to the extent that disambiguation reduces the number of possible sentence continuations.

Em todos os doentes, as medidas nutricionais e de suporte são fundamentais. A abstinência alcoólica é óbvia e obrigatória; melhora o prognóstico, as lesões histológicas, diminui a pressão portal, a progressão para a cirrose Rapamycin ic50 e melhora a sobrevivência em todas as fases da DHA. Após um episódio da HAA, não há «consumo seguro», sendo bastante provável a recidiva e/ou a evolução para cirrose, especialmente no sexo feminino18. É frequente a desnutrição calórico-proteica em alcoólicos, bem como deficiências em vitaminas e minerais, como as vitaminas A e D, tiamina, folatos, piridoxina e zinco51 and 52. Estas

alterações devem ser identificadas e corrigidas, pois podem ter implicações no prognóstico. Há indicações de que a simples instituição de dieta entérica padrão de 2 000 kcal/d pode ser tão eficaz como a terapêutica médica e, inclusivamente, potenciar a eficácia desta última53 and 54. Nos doentes de alto risco, estão preconizadas outras terapêuticas. Dada a natureza inflamatória da HAA, os anti-inflamatórios esteroides parecem

ser uma terapêutica racional. De facto, na HAA, a administração de corticoides diminui os níveis de citocinas pró-inflamatórias, entre as quais a IL-8 e o TNF-α, para além de várias moléculas de adesão intracelular55 and 56. Esta diminuição parece ser consequência do aumento find more da expressão de uma proteína designada Glucocorticoid-Induced Leucine Zipper (GILZ), que inibe francamente a via do fator nuclear kB e a ativação de monócitos e macrófagos em resposta ao LPS 57. A administração de corticoides tem sido a terapêutica mais estudada na HAA, mas nem por isso é livre de controvérsia. Nos últimos 40 anos, foram publicados 13 estudos acerca da administração de prednisolona na HAA; contudo, a maioria era de pequena dimensão e com populações heterogéneas. A mais recente meta-análise mostra que a administração de prednisolona (40 mg/d durante 4 semanas) se revelou benéfica em termos de redução da mortalidade dos doentes com FDM ≥ 32 e/ou com encefalopatia58. Esta situa-se em 65%, comparativamente aos 84,6% dos não tratados, representando, ainda

Bortezomib order assim, uma diminuição do risco relativo de morte em 30%, com um número necessário para tratar de apenas 545. De salientar que a eficácia da prednisolona, na diminuição da mortalidade a curto prazo, não foi demonstrada em casos muito graves, podendo mesmo ser prejudicial. Com efeito, a existência de pancreatite, hemorragia digestiva, insuficiência renal ou infeção ativa foram critérios de exclusão nos estudos atrás mencionados. Foi sugerido que, com FDM > 54, a mortalidade é maior aquando do tratamento com corticoide59. Existem ainda doentes não respondedores aos corticoides, numa percentagem que pode chegar aos 40%. A decisão de suspender os corticoides pode ser tomada calculando ao sétimo dia o score de Lille, que se baseia nos valores de bilirrubina, albumina, tempo de protrombina, creatinina e idade do doente.

For this comparison, those values resulting in a probability other than zero are considered statistically distinct ( D’Suze and Sevcik, 2010). From the phase plot (ti,Qi), which represents Ts-DF venom (SWS) of Q = D − 1 plotted against the SWS of Q = D − 1 from Ts-MG venom (data not shown), and based

on the non-parametric Spearman rank correlation coefficient (rs, when ds = rs2), the coefficient of determination SB431542 (ds) value obtained was 0.56 and rs (0.75) with P(rs = 0) of 3.19 × 10−20. Considering these values and that plotted points do not tend to cluster around a straight line, it is strengthened that venoms are different. MALDI-TOFMS analyses of Ts-DF and Ts-MG venom chromatographic fractions resulted in the detection of 171 and 174 components whose molecular masses ranged from m/z 1145.6 to 10,988.4 and 1196.8 to 16,457.5, respectively ( Fig. 5-A). Were observed in Ts-DF and Ts-MG venoms 114 corresponding molecular masses. Moreover, 54 (32.1%) were present only in Ts-DF venom, and 70 (38.0%) were exclusive for Ts-MG venom ( Fig. 5-B and Table 4). Ts-DF venom yielded a smaller number of peptides with molecular mass distributed between 6500 and 7500 Da than Ts-MG venom. On the other hand, 5001 to 5500 Da peptides were in higher number in Ts-DF venom than in Ts-MG one ( Figs. 5 and 6). T. serrulatus is considered the most important scorpion species for Public Health in Brazil

( Funasa, 2001 and Funasa, 2009). This is the first study to evaluate the toxicity of the venom of T. serrulatus from DF, Brazil, and the effects it provokes in vivo on murine Dasatinib mw species. We demonstrated that the T. serrulatus venom from Distrito Federal (LD50 of 51.6 μg/mouse) is almost twice (1.98) less toxic than the T. serrulatus (MG)

venom (LD50 of 26.0 μg/mouse). Nishikawa et al. (1994) had previously shown for T. serrulatus the LD50 of 25.5 μg/mouse. The LD50 of the venom of T. serrulatus from Bahia, a northeastern Brazilian state also bordering MG, is 96.16 μg/mouse ( Silva et al., 2005a and Silva et al., 2005b), indicating the existence of differences in the venom of this species from different regions of Brazil. Factors such as milking and storage means of the venom, the route of venom administration on mice, and the observation time course of LD50 experiment could possibly result in different toxicities. However, as the experiments conducted here with both venoms Rolziracetam followed the same protocols, these factors were controlled, being the origin of scorpions the most acceptable hypothesis to reinforce the assertion for regional venom variation. The neurotoxins were the most important compounds of scorpion venom, acting on ion channels and resulting in an expressive release of acetylcholine, noradrenaline and adrenaline affecting both the sympathetic and parasympathetic systems, inducing physiological and behavioral changes (Henriques et al., 1968, Ismail, 1995, Dávila et al., 2002, Vasconcelos et al., 2005, Cupo et al.

There are a considerable number of publications and patents on the application of vitrification for tissue and whole organ preservation including kidney [32], liver slices [29] and blood vessels [55]. click here Most tissues studied were either vascular or were organ slices, in both cases the CPA equilibration time throughout the tissue could be effectively reduced by the perfusion of the CPA solution or adjusting the tissue slice thickness [56]. The

earliest accounts of vitrification of articular cartilage are from Jomha et al. [45] and [46]. These two studies demonstrated 42% and 33% cell recovery respectively after vitrification using high concentrations of Me2SO. Song et al. achieved ∼80% chondrocyte viability (Alamar Blue and calcein-AM fluorescent functional assays) in vitrified rabbit full thickness femoral head cartilage. Using cryosubstitution, it was shown that vitrification, or in other words ice-free cryopreservation, was truly achieved [96]. In another study, scanning electron microscopy of the cartilage samples immersed and fast-cooled in ⩾6 M DMSO solution showed a

decrease in the size and total volume of http://www.selleckchem.com/products/MG132.html the enlarged pores due to ice formation [48]. Further evidence of the protection of extracellular matrix from ice formation damage was provided by multiphoton fluorescent imaging of cartilage grafts and Raman spectroscopy of heart valve leaflets, concluding that the tissue extracellular matrix received more extensive damage when frozen with a conventional slow-freezing than when vitrified [18] and [105]. Since the concentrations required for vitrification are generally high, a number of studies have investigated CPA toxicity at high concentrations in cartilage and other tissues providing some valuable information although the data is far from complete. It is clear that CPA toxicity is species and tissue specific; therefore, these results cannot be generalized [5], [23], Dynein [85], [88], [104] and [111]. There are few studies investigating the mechanisms

of toxicity and the effects of high concentrations of CPAs [7], [13], [26], [28], [32] and [113]. More recently, a few studies have investigated CPA toxicity specific to articular cartilage with some general trends in CPA toxicity to chondrocytes and CPA interactions developing [6], [26] and [53]. The specifics of cellular toxicity are not clearly defined at this point and methods of mitigating toxicity of specific CPAs are not available; however the general consensus in the field of cryobiology is to expose cells to the CPA at the lowest concentration and temperature for the shortest exposure time possible so the formation of ice is avoided. This method is called liquidus tracking or stepwise loading and cooling.

Moreover, methodological problems involved in isolation of veins and venules commit study of this vascular bed. In spite of this, isolated portal vein and perfused mesenteric venular bed preparations have been used in biological research to asses venous function in view of the fact that these preparations respond to a variety of vasoactive

agents [32] and [37]. Since splanchnic venous bed accommodates about 25% of the total blood volume [32] and mesenteric vascular bed can be destination for 10% of cardiac output [37], investigation of venous responses at these vascular regions could BIRB 796 order yield important information about circulatory function and control of blood pressure. The renin-angiotensin system (RAS) is a coordinated hormonal cascade important to the regulation of renal sodium excretion and blood pressure. Angiotensin II (Ang II), the main effector peptide of RAS, binds two major receptors, AT1 and AT2 (AT1R and AT2R) [38]. The vast majority of Ang II actions occur via the AT1R binding, including vasoconstriction, cellular proliferation, and activation of the sympathetic nervous system [35]. The actions of Ang II mediated by AT2R are less well understood; however, it is known that AT2R stimulation includes vasodilation, inhibition of cell

proliferation and modulation of growth and remodeling in fetal vasculature [3]. Ang II promotes vasoconstriction in isolated mesenteric venules [8] and [37] and portal vein preparations [8], [12], [18] and [23] Nutlin-3a supplier of normotensive rats; however, to our knowledge, the vascular effects of Ang II either in veins or venules from hypertensive rats have not been evaluated. Thus, the aim of the present study was to investigate the effects of Ang II in the mesenteric venular bed and in the circular muscle of portal veins from spontaneously hypertensive Amylase rats (SHR) by evaluating the participation of AT1R and AT2R on Ang II response. In addition, we analyzed the role of cyclooxygenase (COX) metabolites, nitric oxide

(NO), and the kinin B2R in modulating Ang II-mediated constriction in SHR. Male Wistar and SHRs weighing 200–300 g were obtained from the Institute of Biomedical Sciences of the University of São Paulo (ICB-USP). All of the animal experiments were conducted in accordance with the guidelines of the Ethic Committee for Research of ICB-USP and conformed to the Guide for the Care and Use of Laboratory Animals published by the United States National Institutes of Health (NIH publication No. 85-23, revised 1996). Animals were kept in a temperature-controlled room on a 12 h light/12 h dark cycle with 60% humidity, standard rat chow, and water ad libitum. Isolated perfused mesenteric venular bed preparations were performed according to the method previously described [37].

During ESD, the strength and the direction of traction were changed to get the efficient traction and the optimal dissection Thiazovivin plane by pushing, pulling, rotating and bending the steerable grasper.

A total of 28 ESDs were performed in 8 pigs (14 ESDs in each group). Mean specimen size was 1320.0 ± 207.8 vs. 1251.8 ± 183.3mm2 (p=ns), mean total procedure time was 63.9 ± 10.0 vs. 42.8 ± 7.8 min (p=0.021), and mean dissection speed was 22.0 ± 6.0 vs. 39.7 ± 12.4mm2/min (p=0.031) in the C-ESD and SG-ESD group respectively. Perforation rate of C-ESD group was 28.6% (4/14) whereas no perforation occurred in SG-ESD group. All perforations in the C-ESD group occurred at proximal sites such as 34 and 40cm. In conclusion, controllable traction ensured faster and safer colonic ESD in the porcine model. We expect this method could reduce the technical difficulty of colonic ESD in humans, and that it could well be helpful to novice and intermediate level endoscopists, and even experts on certain occasions. “
“Through injection of bulking agents, radiofrequency and variations of fundoplication, multiple endoscopic approaches

to the therapy of GERD have focused on increasing cardia/lower esophageal sphincter narrowing. Dysphagia following band ligation, secondary to scar formation, is not uncommon in both variceal band ligation and endoscopic mucosal resection. The therapeutic impact of targeted band ligation with/without mucosectomy on GERD patients was evaluated up to 12 months of follow up. Patients with documented PPI responsive GERD Sunitinib manufacturer with an abnormal pH study underwent targeted band ligation with/without mucosectomy. Band ligation was performed in all four Phospholipase D1 quadrants not more than 5 mm distal to the Z-line and in 3 or 4 quadrants not more than 5 mm proximal

to the Z-line. Patient were randomized by sealed envelope to band ligation vs. band ligation with mucosectomy and blinded to the therapy performed. Six months after the procedure, all patients completed a medication history, GERD-HQRL questionnaire and underwent repeat pH testing. With the exception of repeat pH testing, this data was compiled at 12 months as well. 10 patients participated in the trial, half of whom underwent band ligation with mucosectomy. No procedural complications occurred. All patients had complete 6 month data and 7/10 patients have complete 12 month data. All patients are expected to have complete 12 month data by May, 2013. Three patients reported de novo dysphagia, one required dilation. Mean HQRL scores (off medications) improved from 26.6 to 9 at 6 months and 6.9 at 12 months, with 60% and 71% of scores normalizing at those respective time points. Improvement was noted in the band-ligation with mucosectomy group, with mean HQRL scores improving from 26.2 to 7.4 at 6 months and 7.5 at 12 months with band-ligation alone, with mean HQRL scores improving from 27 to 10.6 at 6 months and 6 at 12 months (See Figure 1).

Enteral nutrition is the recommended route of intake. Human milk is preferred for infants. Marthe J. Moseley Chronic critical illness is a problem in the critical care environment. The ultimate goal in managing care for the chronically critically ill is liberation from mechanical ventilation, leading to improved survival and enhanced quality of life. Clinical see more practice guidelines are presented as a framework in providing care for this distinct patient population. Research studies supplement the recommendations to ensure best care guides critical care decisions using the best evidence in the context of patient values and clinical expertise. Jan Powers and Karen Samaan Malnutrition has been identified as a cause for disease as well

as a condition resulting from inflammation associated with acute or chronic disease. Malnutrition is common in acute-care settings, occurring in 30% to 50% of hospitalized patients. Inflammation has been associated with malnutrition and malnutrition has been associated with compromised immune status, infection, and increased intensive care unit (ICU) and hospital lengths of stay. The ICU nurse is in the best position to advocate for appropriate nutritional therapies and NADPH-oxidase inhibitor facilitate the safe delivery of nutrition. Jody Collins Nutrition and care considerations in the overweight

and obese population within the critical care setting are multifaceted. Patients requiring critical care have specialized care management needs that often

times challenge health care providers. When patients are obese, this further complicates the physiologic aspects of healing, thus creating challenges to meeting both the nutritional needs of the individual and hampering treatment. This article reviews the care considerations, physiology of bariatric patients, and challenges of providing safe and quality care, including current evidence-based practice strategies developed to provide optimal support for obese patients during hospitalization and within the critical care setting. Gordana Bosnic This article presents an overview of postoperative DNA Synthesis inhibitor nutritional requirements and goals following bariatric surgery. It summarizes current diet progression and nutrient intake guidelines geared toward optimizing weight loss and maintaining adequate nutritional status, nutrient absorption, as well as hydration. The article further emphasizes the importance of postoperative follow-up with a bariatric multidisciplinary team for appropriate postoperative care, diet management, and nutrient deficiency screenings. Miranda K. Kelly Enteral nutrition is an important aspect of caring for critically ill patients, yet delays in implementation of guidelines and recommendations occur. Bedside caregivers are in a key position to evaluate current practice and lead change to implement evidence-based practice guidelines. Interdisciplinary teams can use change models, such as Larrabee’s, to provide guidance and support success of practice change projects.

It should also be noted that this variable gives only the first stranding time of the oil, and a large part of the oil slick may actually still be floating around in the sea, arriving at the shore later. Variables of this type are dependent on one or more other variables, called parents. The relations between a conditional variable (child) ABT-737 order and its parents are established through a conditional probability table (CPT). A CPT for the model presented here is determined in two fold. First, mathematical functions are adopted when applicable to specify the relations between variables. Second, simulations are performed and the results are incorporated to the model. In

this section, all the conditional variables are listed and their origin is explained. The variable Wave height is conditional on the variable Season, and is divided into four different intervals, as presented in Table 5. The probability distributions, which

are adopted for this variable, are based on field measurements performed in the Gulf of Finland, see Kahma and Pettersson (1993). As the Gulf of Finland is quite narrow, the highest measured significant wave height is 5.2 m, which has been recorded only twice in the history until 2013, see Marita Mustonen (2013). However, a wave height of approximately two meters already makes it almost impossible for the current Finnish oil-combating vessels to carry out oil-recovery operations. This variable reflects the fraction of an oil spill that evaporates into the air, and

is expressed as a percentage of the initial spill size. The rate at selleck products which the oil evaporates depends, among other factors on the oil type in question, the weather circumstances, such as wind and wave height, as well as the prevailing temperature. Evaporation is also affected by the initial spreading rate of the oil, since the larger the surface area is, the faster light components will evaporate – see for example Yamada (2009). However, this particular dependency is not taken into consideration here. In order to calculate the CPT we use the following equation, see Juntunen (2005): equation(1) Evaporation=f1(oil Clomifene type)·f2(wave height)·f3(season)Evaporation=f1(oil type)·f2(wave height)·f3(season)where Evaporation is the fraction of an initial spill that evaporated (%) and the following factors are used to determine this parameter: f1 (light oil) = 0.8; f1 (medium oil) = 0,3; f1 (heavy oil) = 0,15; This variable quantifies the amount of oil that is still left in the water after considering the possible effect of the evaporation. The variable exists in 17 states ranging from 0 (all of the oil has evaporated) to 50,000 cubic meters. This node quantifies the time that oil-combating fleet may gain by utilizing the offshore booms, which prevent the oil spill from spreading quickly. The probabilities for this variable are elicited from the experts, and are presented in Table 6.
