    We performed a study to assess the effectiveness of a fluid infusion strategy currently used in the military pre-hospital environment using the patient's own body weight as an infusion device. Thirteen healthy volunteers were cannulated and 0.9% sodium chloride infused over a period of ten minutes. The volumes infused were measured and flow rates derived. A mean flow rate of 40 ml per minute was seen through an 18 g cannula. This strategy generates reasonable flow rates, but whether this is sufficient to the clinical aim of fluid resuscitation in pre-hospital settings is unknown.

    Oxygen is an essential part of the most important metabolic pathways in aerobic organisms. Oxygen delivery is merely dependent on blood, rendering blood loss a devastating event. Traumatic pre-hospital liver bleeding is a major cause of early trauma deaths in human and animals, with no established therapeutic method yet. Increasing intra-abdominal pressure (IAP) has been shown to reduce liver bleeding by half. Although reduction of blood loss could be in favor of blood oxygen delivery, however, the complex interaction between increased IAP and respiratory mechanics during severe hemorrhagic shock remained unclear. We used a novel model of liver trauma in 16 rabbits and randomly assigned them to either normotensive abdomen group or increased IAP by fluid infusion (HA) groups (n=8 each). Liver size and the amount of liver injury were evaluated. Various blood oxygenation parameters were recorded. Both groups were identical in terms of the liver size and injury. The HA group had significantly lower shock index. Arterial oxygen capacity and oxygen content were higher in the HA group. No significant statistical difference was seen between groups in terms of abdominal perfusion pressure; alveolar pressure of oxygen; dissolved oxygen in blood plasma; alveolar to arterial oxygen tension gradient; arterial to alveolar oxygen pressure ratio; the ratio between partial pressure of arterial oxygen and fraction of inspired oxygen; and respiratory index. In conclusion, the novel therapeutic method of increasing IAP by fluid infusion in a rabbit model of liver hemorrhage preserved blood oxygenation better than the classic therapeutic method.

    There is growing interest in the use of blood components for pre-hospital resuscitation of patients with major traumatic haemorrhage. It has been speculated that early resuscitation with blood components may have benefits in terms of treating trauma-induced coagulopathy, which in turn may influence survival. The proposed systematic review will evaluate the evidence on the clinical effectiveness of pre-hospital blood components (red blood cells and/or plasma or whole blood), in both civilian and military settings, compared with other resuscitation strategies in patients with major traumatic haemorrhage. Standard systematic review methods aimed at minimising bias will be employed for study identification, selection and data extraction. General medical and specialist databases will be searched; the search strategy will combine terms for the population, intervention and setting. Studies will be selected for review if the population includes adult patients with major traumatic haemorrhage who receive blood components in a pre-hospital setting (civilian or military). Systematic reviews, randomised and non-randomised controlled trials and controlled observational studies will be included. Uncontrolled studies will be considered depending on the volume of controlled evidence. Quality assessment will be tailored to different study designs. Both patient related and surrogate outcomes will be considered. Synthesis is likely to be primarily narrative, but meta-analyses and subgroup analyses will be undertaken where clinical and methodological homogeneity exists. Given the increasing use by emergency services of blood components for pre-hospital resuscitation, this is a timely systematic review, which will attempt to clarify the evidence base for this practice. As far as the authors are aware, the proposed systematic review will be the first to address this topic. PROSPERO CRD42014013794.

    Pre-hospital care is emergency medical care given to patients before arrival in hospital after activation of emergency medical services. It traditionally incorporated a breadth of care from bystander resuscitation to statutory emergency medical services treatment and transfer. New concepts of care including community paramedicine, novel roles such as emergency care practitioners, and physician delivered pre-hospital emergency medicine are re-defining the scope of pre-hospital care. For severely ill or injured patients, acting quickly in the pre-hospital period is crucial with decisions and interventions greatly affecting outcomes. The transfer of skills and procedures from hospital care to pre-hospital medicine enables early advanced care across a range of disciplines. The variety of possible pathologies, challenges of environmental factors, and hazardous situations requires management that is tailored to the patient's clinical need and setting. Pre-hospital clinicians should be generalists with a broad understanding of medical, surgical, and trauma pathologies, who will often work from locally developed standard operating procedures, but who are able to revert to core principles. Pre-hospital emergency medicine consists of not only clinical care, but also logistics, rescue competencies, and scene management skills (especially in major incidents, which have their own set of management principles). Traditionally, research into the hyper-acute phase (the first hour) of disease has been difficult, largely because physicians are rarely present and issues of consent, transport expediency, and resourcing of research. However, the pre-hospital phase is acknowledged as a crucial period, when irreversible pathology and secondary injury to neuronal and cardiac tissue can be prevented. The development of pre-hospital emergency medicine into a sub-specialty in its own right should bring focus to this period of care.

    During calculating the fluid resistence with Herschel-Bulkley formula, the deviation is very large in some regions. In order to decrease the deviation, the optimized parameters of approximate solution are obtained through mathematic analysis and 3-D optimization calculation. In the close region of relative radius of the core flow, the continuity of deviation is determined with the limit methods. By analysis, the results indicate that the deviation in the area around the discontinuous nodes is very large; the deviation is the function of fluid parameters, approximate solution parameters and the relative radius of the core flow. While the fluid parameters keep certain, the 3-D figures of the deviation are drawn. The slice plane is used to seek the extremums of multi-peaks surface; The optimized parameters of approximate formula make the approximate formula in the regions of the certain deviation. The available area of relative radius of the core flow increases by 43.2%. It is more valuable for the calculation of flow resistance in pipe transportation.

    After a brief outline of past developments in the training of ambulance personnel, this paper traces the adoption in the UK of Pre-Hospital Trauma Life Support (PHTLS) courses from the US. The 1991 World Student Games in Sheffield, UK led to liaison between training staff from South Yorkshire Metropolitan Ambulance and Paramedic Service (SYMAPS) and from Western New York Medical Training Institute. As a result, the trauma care policy of SYMAPS was altered from aiming to stabilise the patient at the scene of the accident to emphasising rapid and thorough assessment, packaging and transport. This is a resume of the scope of the PHTLS provider course. The course concentrates on the principles of PHTLS for the multisystems trauma victim.

    The calcium signaling plays a vital role in flow-dependent vascular endothelial cell (VEC) physiology. Variations in fluid shear stress and ATP concentration in blood vessels can activate dynamic responses of cytosolic-free [Formula: see text] through various calcium channels on the plasma membrane. In this paper, a novel dynamic model has been proposed for transient receptor potential vanilloid 4 [Formula: see text]-mediated intracellular calcium dynamics in VECs induced by fluid shear stress and ATP. Our model includes [Formula: see text] signaling pathways through P2Y receptors and [Formula: see text] channels (indirect mechanism) and captures the roles of the [Formula: see text] compound channels in VEC [Formula: see text] signaling in response to fluid shear stress (direct mechanism). In particular, it takes into account that the [Formula: see text] compound channels are regulated by intracellular [Formula: see text] and [Formula: see text] concentrations. The simulation studies have demonstrated that the dynamic responses of calcium concentration produced by the proposed model correlate well with the existing experimental observations. We also conclude from the simulation studies that endogenously released ATP may play an insignificant role in the process of intracellular [Formula: see text] response to shear stress.

    Hypothermia is associated with increased morbidity and mortality in trauma patients and poses a challenge in pre-hospital treatment. The aim of this study was to identify equipment to prevent, diagnose, and treat hypothermia in Norwegian pre-hospital services. In the period of April-August 2011, we conducted a survey of 42 respondents representing a total of 543 pre-hospital units, which included all the national ground ambulance services, the fixed wing and helicopter air ambulance service, and the national search and rescue service. The survey explored available insulation materials, active warming devices, and the presence of protocols describing wrapping methods, temperature monitoring, and the use of warm i.v. fluids. Throughout the services, hospital duvets, cotton blankets and plastic "bubble-wrap" were the most common insulation materials. Active warming devices were to a small degree available in vehicle ambulances (14%) and the fixed wing ambulance service (44%) but were more common in the helicopter services (58-70%). Suitable thermometers for diagnosing hypothermia were lacking in the vehicle ambulance services (12%). Protocols describing how to insulate patients were present for 73% of vehicle ambulances and 70% of Search and Rescue helicopters. The minority of Helicopter Emergency Medical Services (42%) and Fixed Wing (22%) units was reported to have such protocols. The most common equipment types to treat and prevent hypothermia in Norwegian pre-hospital services are duvets, plastic "bubble wrap", and cotton blankets. Active external heating devices and suitable thermometers are not available in most vehicle ambulance units.

    Full Text Available Abstract Background To assess, whether arterial blood gas measurements during trauma patient's pre-hospital shock resuscitation yield useful information on haemodynamic response to fluid resuscitation by comparing haemodynamic and blood gas variables in patients undergoing two different fluid resuscitation regimens. Methods In a prospective randomised study of 37 trauma patients at risk for severe hypovolaemia, arterial blood gas values were analyzed at the accident site and on admission to hospital. Patients were randomised to receive either conventional fluid therapy or 300 ml of hypertonic saline. The groups were compared for demographic, injury severity, physiological and outcome variables. Results 37 patients were included. Mean (SD Revised Trauma Score (RTS was 7.3427 (0.98 and Injury Severity Score (ISS 15.1 (11.7. Seventeen (46% patients received hypertonic fluid resuscitation and 20 (54% received conventional fluid therapy, with no significant differences between the groups concerning demographic data or outcome. Base excess (BE values decreased significantly more within the hypertonic saline (HS group compared to the conventional fluid therapy group (mean BE difference -2.1 mmol/l vs. -0.5 mmol/l, p = 0.003. The pH values on admission were significantly lower within the HS group (mean 7.31 vs. 7.40, p = 0.000. Haemoglobin levels were in both groups lower on admission compared with accident site. Lactate levels on admission did not differ significantly between the groups. Conclusion Pre-hospital use of small-volume resuscitation led to significantly greater decrease of BE and pH values. A portable blood gas analyzer was found to be a useful tool in pre-hospital monitoring for trauma resuscitation.

    Road traffic injuries are responsible for a vast number of trauma-related deaths in middle- and low-income countries. Pre-hospital emergency medical service (PHEMS) provides care and transports the injured patients from the scene of accident to the destined hospital. The PHEMS providers and paramedics were recently trained in the Pre Hospital Trauma Life Support (PHTLS) guidelines to improve the outcome of trauma patients in developing countries. We decided to carry out a study on the success rate of PHEMS personnel in implementing PHTLS guidelines at the scene of trauma. Severe trauma patients who had been transferred to the emergency department were included in the study. Evaluations included transfer time, airway management, spinal immobilization, external bleeding management, intravenous (IV) line access, and fluid therapy. All evaluations were performed by an expert emergency physician in the emergency department. The mean response time was 17.87±9.1 minutes. The PHEMS personnel immobilized cervical spine in 60.4% of patients, out of whom 16.7% were not properly immobilized. Out of 99 (98%) cases of established IV line access by the PHEMS providers, 57% were satisfactory. Fluid therapy, which was carried out in 99 (98%) patients by the PHEMS personnel, was appropriate in 92% of the cases. PHEMS personnel need more education and supervising to provide services according to PHTLS guidelines.

    Assessment and management of pain in pre-hospital care settings are important aspects of paramedic and clinical team roles. As emergency department waiting times and delays in paramedic-to-nurse handover increase, it becomes more and more vital that patients receive adequate pre-hospital pain relief. However, administration of analgesia can be inadequate and can result in patients experiencing oligoanalgesia, or under-treated pain. This article examines these issues along with the aetiology of trauma and the related socioeconomic background of traumatic injury. It reviews validated pain-assessment tools, outlines physiological responses to traumatic pain and discusses some of the misconceptions about the provision of effective analgesia in pre-hospital settings.

    Full Text Available Background: Most of the bad outcomes in patients with severe traumatic brain injury (TBI are related to the presence of a high incidence of pre-hospital secondary brain insults. Therefore, knowledge of these variables and timely management of the disease at the pre-hospital period can significantly improve the outcome and decrease the mortality. The Brain Trauma Foundation guideline on "Prehospital Management" published in 2008 could provide the standardized protocols for the management of patients with TBI; however, this guideline has included the relevant papers up to 2006. Methods: A PubMed search for relevant clinical trials and reviews (from 1 January 2007 to 31 March 2013, which specifically discussed about the topic, was conducted. Results: Based on the evidence, majority of the management strategies comprise of rapid correction of hypoxemia and hypotension, the two most important predictors for mortality. However, there is still a need to define the goals for the management of hypotension and inclusion of newer difficult airway carts as well as proper monitoring devices for ensuring better intubation and ventilatory management. Isotonic saline should be used as the first choice for fluid resuscitation. The pre-hospital hypothermia has more adverse effects; therefore, this should be avoided. Conclusion: Most of the management trials published after 2007 have focused mainly on the treatment as well as the prevention strategies for secondary brain injury. The results of these trials would be certainly adopted by new standardized guidelines and therefore may have a substantial impact on the pre-hospital management in patients with TBI.

  15. An analytical formula for the longitudinal resonance frequencies of a fluid-filled crack

    The fluid-filled crack model (Chouet, 1986, JGR) simulates the resonances of a rectangular crack filled with an inviscid fluid embedded in a homogeneous isotropic elastic medium. The model demonstrates the existence of a slow wave, known as the crack wave, that propagates along the solid-fluid interfaces. The wave velocity depends on the crack stiffness. The model has been used to interpret the peak frequencies of long-period (LP) and very long period (VLP) seismic events at various volcanoes (Chouet and Matoza, 2013, JVGR). Up to now, crack model simulations have been performed using the finite difference (Chouet, 1986) and boundary integral (Yamamoto and Kawakatsu, 2008, GJI) methods. These methods require computationally extensive procedures to estimate the complex frequencies of crack resonance modes. Establishing an easier way to calculate the frequencies of crack resonances would help understanding of the observed frequencies. In this presentation, we propose a simple analytical formula for the longitudinal resonance frequencies of a fluid-filled crack. We first evaluated the analytical expression proposed by Kumagai (2009, Encyc. Complex. Sys. Sci.) through a comparison of the expression with the peak frequencies computed by a 2D version of the FDM code of Chouet (1986). Our comparison revealed that the equation of Kumagai (2009) shows discrepancies with the resonant frequencies computed by the FDM. We then modified the formula as fmL = (m-1)a/[2L(1+2ɛmLC)1/2], (1) where L is the crack length, a is the velocity of sound in the fluid, C is the crack stiffness, m is a positive integer defined such that the wavelength of the normal displacement on the crack surface is 2L/m, and ɛmL is a constant that depends on the longitudinal resonance modes. Excellent fits were obtained between the peak frequencies calculated by the FDM and by Eq. (1), suggesting that this equation is suitable for the resonant frequencies. We also performed 3D FDM computations of the

    Full Text Available Abstract Background Poisoned patients are often treated in and discharged from pre-hospital health care settings. Studies of poisonings should therefore not only include hospitalized patients. Aims: To describe the acutely poisoned patients treated by ambulance personnel and in an outpatient clinic; compare patients transferred to a higher treatment level with those discharged without transfer; and study the one-week mortality after pre-hospital discharge. Methods A one-year multi-centre study with prospective inclusion of all acutely poisoned patients ≥ 16 years of age treated in ambulances, an outpatient clinic, and hospitals in Oslo. Results A total of 3757 health service contacts from 2997 poisoning episodes were recorded: 1860 were treated in ambulances, of which 15 died and 750 (40% were discharged without transfer; 956 were treated in outpatient clinic, of which 801 (84% were discharged without transfer; and 941 episodes were treated in hospitals. Patients discharged alive after ambulance treatment were mainly poisoned by opiates (70%, were frequently comatose (35%, had respiratory depression (37%, and many received naloxone (49%. The majority of the patients discharged from the outpatient clinic were poisoned by ethanol (55%, fewer were comatose (10%, and they rarely had respiratory depression (4%. Among the hospitalized, pharmaceutical poisonings were most common (58%, 23% were comatose, and 7% had respiratory depression. Male patients comprised 69% of the pre-hospital discharges, but only 46% of the hospitalized patients. Except for one patient, who died of a new heroin overdose two days following discharge from an ambulance, there were no deaths during the first week after the poisonings in the 90% of the pre-hospital discharged patients with known identity. Conclusion More than half of the poisoned patients treated in pre-hospital treatment settings were discharged without transfer to higher levels. These poisonings were more often

    The traditional communication infrastructure of the pre-hospital Emergency Medical System (EMS) is limited to voice communication using radio or cell phone technologies. With the emergence of 3rd Generation wireless networks (3G) and enhanced mobile devices capable of data communication (e.g., mobile tablets, PDAs with cell phones, or cell phones with PDA capabilities), the voice communication can be enhanced with interactive data messaging and perhaps even with interactive video communication. However, video requires substantially more bandwidth which 4th Generation (4G) systems are promising. However, their availability is limited. We present an infrastructure that allows dynamic selection of the best data transport mode in the pre-hospital EMS environment.

    Full Text Available Introduction: Since pre-hospital emergency staff, who play a vital role in saving peoples’ lives, work under a lot of pressure, determining the rate and dangers of their job burnout is very important. Therefore, this study was carried out to determine the job burnout rate of the pre-hospital emergency staff in Isfahan, Iran. Methods: In this cross-sectional study, all of the pre-hospital emergency staff in all emergency operation centers in Isfahan were included. Using the standard Maslach burnout inventory questionnaire, the job burnout rate of emergency technicians was measured. The studied aspects were frequency and intensity of emotional exhaustion, depersonalization and personal accomplishment feeling, which were then divided into 3 levels (low, average and high according to the intensity and frequency of these feelings. Results: In the end, 68 technicians were involved in this study (Mean age 26.97±7.7; 42.6% single. Regarding intensity, their mean emotional exhaustion score was 25.59±20.39, depersonalization score was 10.57±7.83 and personal accomplishment feeling was 34.6±8.46. Moreover, the mean emotional exhaustion frequency was 21.21±11.95 (low level, depersonalization frequency was 8.94±5.43 (low level and personal accomplishment feeling frequency was 26.82±5.72 (high level. Conclusion: The data obtained in this study shows that the pre-hospital emergency technicians in Isfahan show average levels of emotional exhaustion and depersonalization intensity and frequency and feel highly unaccomplished.

    The right person in the right place and at the right time is not always possible; telemedicine offers the potential to give audio and visual access to the appropriate clinician for patients. Advances in information and communication technology (ICT) in the area of video-to-video communication have led to growth in telemedicine applications in recent years. For these advances to be properly integrated into healthcare delivery, a regulatory framework, supported by definitive high-quality research, should be developed. Telemedicine is well suited to extending the reach of specialist services particularly in the pre-hospital care of acute emergencies where treatment delays may affect clinical outcome. The exponential growth in research and development in telemedicine has led to improvements in clinical outcomes in emergency medical care. This review is part of the LiveCity project to examine the history and existing applications of telemedicine in the pre-hospital environment. A search of electronic databases including Medline, Excerpta Medica Database (EMBASE), Cochrane, and Cumulative Index to Nursing and Allied Health Literature (CINAHL) for relevant papers was performed. All studies addressing the use of telemedicine in emergency medical or pre-hospital care setting were included. Out of a total of 1,279 articles reviewed, 39 met the inclusion criteria and were critically analysed. A majority of the studies were on stroke management. The studies suggested that overall, telemedicine had a positive impact on emergency medical care. It improved the pre-hospital diagnosis of stroke and myocardial infarction and enhanced the supervision of delivery of tissue thromboplasminogen activator in acute ischaemic stroke. Telemedicine presents an opportunity to enhance patient management. There are as yet few definitive studies that have demonstrated whether it had an effect on clinical outcome.

    We report prospectively recorded observational data from consecutive cases in which the attending pre-hospital critical care anaesthesiologist considered performing pre-hospital advanced airway management but decided to withhold such interventions. Anaesthesiologists from eight pre-hospital critical care teams in the Central Denmark Region (a mixed rural and urban region with 1.27 million inhabitants) registered data from February 1st 2011 to October 31st 2012. Included were patients of all ages for whom pre-hospital advanced airway management were considered but not performed. The main objectives were to investigate (1) the pre-hospital critical care anaesthesiologists' reasons for considering performing pre-hospital advanced airway management in this group of patients (2) the pre-hospital critical care anaesthesiologists' reasons for not performing pre-hospital advanced airway management (3) the methods used to treat these patients (4) the incidence of complications related to pre-hospital advanced airway management not being performed. We registered data from 1081 cases in which the pre-hospital critical care anaesthesiologists' considered performing pre-hospital advanced airway management. The anaesthesiologists decided to withhold pre-hospital advanced airway management in 32.1% of these cases (n = 347). In 75.1% of these cases (n = 257) pre-hospital advanced airway management were withheld because of the patient's condition and in 30.8% (n = 107) because of patient co-morbidity. The most frequently used alternative treatment was bag-mask ventilation, used in 82.7% of the cases (n = 287). Immediate complications related to the decision of not performing pre-hospital advanced airway management occurred in 0.6% of the cases (n = 2). We have illustrated the complexity of the critical decision-making associated with pre-hospital advanced airway management. This study is the first to identify the most common reasons why pre-hospital critical care

    Pre-hospital advanced airway management has been named one of the top-five research priorities in physician-provided pre-hospital critical care. Few studies have been made on paediatric pre-hospital advanced airway management. The aim of this study was to investigate pre-hospital endotracheal intubation success rate in children, first-pass success rates and complications related to pre-hospital advanced airway management in patients younger than 16 years of age treated by pre-hospital critical care teams in the Central Denmark Region (1.3 million inhabitants). A prospective descriptive study based on data collected from eight anaesthetist-staffed pre-hospital critical care teams between February 1st 2011 and November 1st 2012. Primary endpoints were 1) pre-hospital endotracheal intubation success rate in children 2) pre-hospital endotracheal intubation first-pass success rate in children and 3) complications related to prehospital advanced airway management in children. The pre-hospital critical care anaesthetists attempted endotracheal intubation in 25 children, 13 of which were less than 2 years old. In one patient, a neonate (600 g birth weight), endotracheal intubation failed. The patient was managed by uneventful bag-mask ventilation. All other 24 children had their tracheas successfully intubated by the pre-hospital critical care anaesthetists resulting in a pre-hospital endotracheal intubation success rate of 96 %. Overall first pass success-rate was 75 %. In the group of patients younger than 2 years old, first pass success-rate was 54 %. The total rate of airway management related complications such as vomiting, aspiration, accidental intubation of the oesophagus or right main stem bronchus, hypoxia (oxygen saturation advanced airway management. Compared with the total population of patients receiving pre-hospital advanced airway management in our system, the overall success rate following pre-hospital endotracheal intubations in children is acceptable but

    Full Text Available Introduction: Stroke is recognized as the third cause of mortality after cardiovascular and cancer diseases, so that lead to death of about 5 million people, annually. There are several scales to early prediction of at risk patients and decreasing the rate of mortality by transferring them to the stroke center. In the present study, the accuracy of Cincinnati pre-hospital stroke scale was assessed. Methods: This was a retrospective cross-sectional study done to assess accuracy of Cincinnati scale in prediction of stroke probability in patients referred to the emergency department of Poursina Hospital, Rasht, Iran, 2013 with neurologic symptoms. Three criteria of Cincinnati scale including facial droop, dysarthria, and upper extremity weakness as well as the final diagnosis of patients were gathered. Sensitivity, specificity, predictive values, and likelihood ratios of Cincinnati scale were calculated using SPSS version 20. Results: 448 patients were assessed. The agreement rate of Cincinnati scale and final diagnosis was 0.483 ± 0.055 (p<0.0001. The sensitivity of 93.19% (95% Cl: 90.11-95.54, specificity of 51.85% (95% Cl: 40.47-63.10, positive predictive value of 89.76% (95% Cl: 86.27-92.62, negative predictive value of 62.69% (95% Cl: 55.52-72.45, positive likelihood ratio of 1.94% (95% Cl: 1.54-2.43, and negative likelihood ratio of 0.13% (95% Cl: 0.09-0.20 were calculated. Conclusion: It seems that pre-hospital Cincinnati scale can be an appropriate screening tool in prediction of stroke in patients with acute neurologic syndromes.

    We report data from the first Utstein-style study of physician-provided pre-hospital advanced airway management. Anaesthesiologists from eight pre-hospital critical care teams in the Central Denmark Region (a mixed rural and urban region with 1.27 million inhabitants) prospectively registered data according to the template for reporting data from pre-hospital advanced airway management. Data collection took place from February 1st 2011 to October 31st 2012. Included were patients of all ages on whom pre-hospital advanced airway management was performed. The objective was to estimate the incidences of failed and difficult pre-hospital endotracheal intubation, and complications related to pre-hospital advanced airway management. The overall incidence of successful pre-hospital endotracheal intubation among 636 intubation attempts was 99.7%, even though 22.4% of pre-hospital endotracheal intubations required more than one intubation attempt. The overall incidence of complications related to pre-hospital advanced airway management was 7.9%. Following rapid sequence intubation, the incidence of first pass success was 85.8%, the overall incidence of complications was 22.0%, the incidence of hypotension 7.3% and that of hypoxia 5.3%. Multiple endotracheal intubation attempts were associated with an increased overall incidence of complications. No airway management related deaths occurred. The overall incidence of successful pre-hospital endotracheal intubations compares to those found in other physician-staffed pre-hospital systems. The incidence of pre-hospital endotracheal intubations requiring more than one attempt is higher than suspected. The incidence of hypotension or hypoxia after pre-hospital rapid sequence intubation compares to those found in UK emergency departments. Pre-hospital advanced airway management including pre-hospital endotracheal intubation performed by experienced anaesthesiologists is associated with high success rates and relatively low

    The surface stiffness of a fluid-saturated porous solid is defined as the ratio between a small change in capillary pressure and the average displacement of the boundary due to the resulting rise or fall of the fluid level in the pore channels. When the surface pores are structurally open, the surface stiffness is entirely due to the stiffness of the microscopic fluid membranes extended by capillary forces over the surface pores. Due to interfacial tension between the immiscible wetting fluid in the pores and nonwetting fluid (air) above the surface, essentially closed-pore boundary conditions can prevail at the interface. It has recently been shown that the surface stiffness of a porous material containing cylindrical pores can be calculated simply as the surface tension of the saturating fluid divided by the static permeability of the porous solid [P. B. Nagy, Appl. Phys. Lett. {bold 60}, 2735 (1992)]. In this letter, we show that the same simple relationship can be generalized for the surface stiffness of fluid-saturated porous media containing parallel prismatic pore channels of any number, size, or shape. {copyright} {ital 1995} {ital American} {ital Institute} {ital of} {ital Physics}.

    The early use of blood products has been associated with improved patient outcomes following severe hemorrhage or traumatic injury. We aimed to investigate the influence of pre-hospital blood products (i.e. plasma and/or RBCs) on admission hemostatic properties and patient outcomes. We hypothesized that pre-hospital plasma would improve hemostatic function as evaluated by rapid thrombelastography (rTEG). We conducted a prospective observational study recruiting 257 trauma patients admitted to a Level I trauma center having received either blood products pre-hospital or in-hospital within 6 hours of admission. Clinical data on patient demographics, blood biochemistry, injury severity score and mortality were collected. Admission rTEG was conducted to characterize the coagulation profile and hemostatic function. 75 patients received pre-hospital plasma and/or RBCs (PH group; nearly half received both RBCs and plasma) whereas 182 patients only received in-hospital blood products (RBCs, Plasma and Platelets) within 6 hours of admission (IH group). PH patients had lower Glasgow coma scale (GCS) scores, more penetrating injuries, lower systolic blood pressures, lower hemoglobin levels, lower platelet counts and greater acidosis upon ED admission than the IH group (all p plasma, more pre-hospital plasma transfusion was tendency towards improved rTEG variables. When adjusting for pre-hospital RBC, pre-hospital plasma was associated with significantly higher rTEG MA (p = 0.012) at hospital admission. After adjusting for pre-hospital RBCs, pre-hospital plasma transfusion was independently associated with increased rTEG MA, as well as arrival indices of shock and hemodynamic instability. Besides more severe injury and worse clinical presentation, the group that received pre-hospital transfusion had early and late mortality similar to patients not transfused pre-hospital. These data suggest that early administration of plasma can provide significant hemostatic and potential

    Pre-hospital observation beds in community care centres have for many years served as an alternative to hospitalisation in rural districts of Norway. The article presents the use of observation beds associated with the Fosen A&E centre. A retrospective review of records of patients who had contacted Fosen A&E centre during the period 21 August 2006-21 August 2009 was undertaken. Patient characteristics and clinical pathways were registered, including admissions to hospital or to an observation bed, as well as re-admissions. Ever since observation beds were first introduced, clear inclusion and exclusion criteria have been applied with regard to the allocation of patients to observation beds. Altogether 8027 patients had been in direct contact with an A&E doctor, and 2342 were admitted, of whom 77% to hospital and 23% to an observation bed. Of the 530 patients admitted to an observation bed, 55% were 70 years or older. Of these, 68% were discharged to their homes within 36 hours, 17% were transferred to hospital, and the remainder received further treatment in a local rehabilitation unit or nursing home. The rate of readmission to observation beds or hospital amounted to 4% among those who had been discharged after no more than three days, and 18% among those discharged after 3-28 days. A low number of readmissions may indicate that the use of observation beds is an alternative to hospitalisation.

    Studies of pre-hospital endotracheal intubation (ETI) from single EMS systems have shown contradictory results, which may represent local differences in paramedic training and experience. An alternative hypothesis is that positive pressure ventilation increases mortality because positive pressure ventilation causes hypotension in severely injured hypovolemic patients. A national sample (National Trauma Data Bank, 1994-2002) was used to minimize effects of local paramedic training and experience. All patients with pre-hospital GCS 16 (most likely to be hypovolemic) were included. Patients intubated in the field (pre-hospital group, n = 871) and in the emergency department (ED group, n = 6581) were compared. To determine whether pre-hospital ETI was an independent predictor of hypotension and mortality, logistic regression was used to control for potential confounders, including age, ISS, body region injured, AIS scores, pre-hospital IV fluids, and other variables. Physiologic variables were not used, as they may be influenced by ETI and positive pressure ventilation, and were therefore considered outcomes, rather than predictors. Groups were comparable in age, gender, anatomic distribution of injuries, likelihood of at least one severe injury (AIS >3) and other variables, except for head injury (ED 83%, pre-hospital 71%, p intubated in the field were more likely to be hypotensive upon arrival in the ED (SBP predictor of hypotension upon arrival in ED (OR 1.7, 95% CI 1.46 -2.09, p endotracheal intubation in trauma patients is associated with hypotension and decreased survival. This may be mediated by the effect of positive pressure ventilation during hypovolemic states.

    Full Text Available Abstract Introduction Endotracheal intubation (ETI has been considered an essential part of pre-hospital advanced life support. Pre-hospital ETI, however, is a complex intervention also for airway specialist like anaesthesiologists working as pre-hospital emergency physicians. We therefore wanted to investigate the quality of pre-hospital airway management by anaesthesiologists in severely traumatised patients and identify possible areas for improvement. Method We performed a risk assessment according to the predictive Bayesian approach, in a typical anaesthesiologist-manned Norwegian helicopter emergency medical service (HEMS. The main focus of the risk assessment was the event where a patient arrives in the emergency department without ETI despite a pre-hospital indication for it. Results In the risk assessment, we assigned a high probability (29% for the event assessed, that a patient arrives without ETI despite a pre-hospital indication. However, several uncertainty factors in the risk assessment were identified related to data quality, indications for use of ETI, patient outcome and need for special training of ETI providers. Conclusion Our risk assessment indicated a high probability for trauma patients with an indication for pre-hospital ETI not receiving it in the studied HEMS. The uncertainty factors identified in the assessment should be further investigated to better understand the problem assessed and consequences for the patients. Better quality of pre-hospital airway management data could contribute to a reduction of these uncertainties.

  14. On-Track Testing as a Validation Method of Computational Fluid Dynamic Simulations of a Formula SAE Vehicle

    Science.gov (United States)

    Weingart, Robert

    This thesis is about the validation of a computational fluid dynamics simulation of a ground vehicle by means of a low-budget coast-down test. The vehicle is built to the standards of the 2014 Formula SAE rules. It is equipped with large wings in the front and rear of the car; the vertical loads on the tires are measured by specifically calibrated shock potentiometers. The coast-down test was performed on a runway of a local airport and is used to determine vehicle specific coefficients such as drag, downforce, aerodynamic balance, and rolling resistance for different aerodynamic setups. The test results are then compared to the respective simulated results. The drag deviates about 5% from the simulated to the measured results. The downforce numbers show a deviation up to 18% respectively. Moreover, a sensitivity analysis of inlet velocities, ride heights, and pitch angles was performed with the help of the computational simulation.

    Full Text Available Purpose: To determine the degree of adherence to a cervical spine (c-spine clearance protocol by pre-hospital Emergency Medical Services (EMS personnel by both self-assessment and receiving hospital assessment, to describe deviations from the protocol, and to determine if the rate of compliance by paramedic self-assessment differed from receiving hospital assessment. Methods: A retrospective sample of pre-hospital (consecutive series and receiving hospital (convenience sample assessments of the compliance with and appropriateness of c-spine immobilization. The c-spine clearance protocol was implemented for Orange County EMS just prior to the April-November 1999 data collection period. Results: We collected 396 pre-hospital and 162 receiving hospital data forms. From the pre-hospital data sheet. the percentage deviation from the protocol was 4.096 (16/396. Only one out of 16 cases that did not comply with the protocol was due to over immobilization (0.2%. The remaining 15 cases were under immobilized, according to protocol. Nine of the under immobilized cases (66% that should have been placed in c-spine precautions met physical assessment criteria in the protocol, while the other five cases met mechanism of injury criteria. The rate of deviations from protocol did not differ over time. The receiving hospital identified 8.0% (13/162; 6/16 over immobilized, 7/16 under immobilized of patients with deviations from the protocol; none was determined to have actual c-spine injury. Conclusion: The implementation of a pre-hospital c-spine clearance protocol in Orange County was associated with a moderate overall adherence rate (96% from the pre-hospital perspective, and 92% from the hospital perspective, p=.08 for the two evaluation methods. Most patients who deviated from protocol were under immobilized, but no c-spine injuries were missed. The rate of over immobilization was better than previously reported, implying a saving of resources.

    Full Text Available Abstract Background Mortality from invasive meningococcal disease (IMD has remained stable over the last thirty years and it is unclear whether pre-hospital antibiotherapy actually produces a decrease in this mortality. Our aim was to examine whether pre-hospital oral antibiotherapy reduces mortality from IMD, adjusting for indication bias. Methods A retrospective analysis was made of clinical reports of all patients (n = 848 diagnosed with IMD from 1995 to 2000 in Andalusia and the Canary Islands, Spain, and of the relationship between the use of pre-hospital oral antibiotherapy and mortality. Indication bias was controlled for by the propensity score technique, and a multivariate analysis was performed to determine the probability of each patient receiving antibiotics, according to the symptoms identified before admission. Data on in-hospital death, use of antibiotics and demographic variables were collected. A logistic regression analysis was then carried out, using death as the dependent variable, and pre-hospital antibiotic use, age, time from onset of symptoms to parenteral antibiotics and the propensity score as independent variables. Results Data were recorded on 848 patients, 49 (5.72% of whom died. Of the total number of patients, 226 had received oral antibiotics before admission, mainly betalactams during the previous 48 hours. After adjusting the association between the use of antibiotics and death for age, time between onset of symptoms and in-hospital antibiotic treatment, pre-hospital oral antibiotherapy remained a significant protective factor (Odds Ratio for death 0.37, 95% confidence interval 0.15–0.93. Conclusion Pre-hospital oral antibiotherapy appears to reduce IMD mortality.

Patients of the 1st group (n=30 received emergency medical assistance from the feldsher teams and patients of the 2nd group (n=40 — from the doctor teams. Expert estimation approach was used for the real practice assessment. Results. The hospital-matched diagnose rate was 97.5% in the doctor teams in comparison with 76.7% in feldsher teams (p<0.05. The efficiency of pre-hospital thrombolysis in 90 minutes after its beginning was 60.1% for the doctor teams versus 73.3% for the feldsher teams (p>0.05. The deviation from the standard operating procedure of the medical care for myocardial infarction patients was observed more often in the doctor teams in comparison with this in the feldsher teams. Time for the decision about pre-hospital thrombolysis start, the rate of unreasonable use or unreasonable refusal of thrombolysis did not differ significantly in feldsher and doctor teams. Conclusion. To increase the effectiveness of pre-hospital thrombolysis therapy it is necessary to follow strictly the standard of the medical care for patients with acute coronary syndrome. One of the main approaches to improve the availability of up to date medical care technologies in STEACS treatment is implementation of pre-hospital thrombolysis in practice of feldsher teams.

    Introduction It is important to gain a thorough understanding of positive coping methods adopted by medical emergency personnel to manage stressful situations associated with accidents and emergencies. Thus, the purpose of this study was to gain a better understanding of positive coping strategies used by emergency medical service providers. Methods This study was conducted using a qualitative content analysis method. The study participants included 28 pre-hospital emergency personnel selected from emergency medical service providers in bases located in different regions of the city of Mashhad, Iran, from April to November 2016. The purposive sampling method also was used in this study, which was continued until data saturation was reached. To collect the data, semistructured open interviews, observations, and field notes were used. Results Four categories and 10 subcategories were extracted from the data on the experiences of pre-hospital emergency personnel related to positive coping strategies. The four categories included work engagement, smart capability, positive feedback, and crisis pioneering. All the obtained categories had their own subcategories, which were determined based on their distinctly integrated properties. Conclusion The results of this study show that positive coping consists of several concepts used by medical emergency personnel, management of stressful situations, and ultimately quality of pre-hospital clinical services. Given the fact that efficient methods such as positive coping can prevent debilitating stress in an individual, pre-hospital emergency authorities should seek to build and strengthen “positive coping” characteristics in pre-hospital medical emergency personnel to deal with accidents, emergencies, and injuries through adopting regular and dynamic policies.

    Conclusion: Pre-hospital delay was mainly patient-related. Hospital delay was mainly related to healthcare resources. Governmental measures to promote ambulance emergency services may reduce the pre-hospital delay, while improving the utilization of healthcare resources may reduce hospital delay.

    Full Text Available Abstract Introduction We describe a system of scenario-based training using simple mannequins under realistic circumstances for the training of pre-hospital care providers. Methods A simple intubatable mannequin or student volunteers are used together with a training version of the equipment used on a routine basis by the pre-hospital care team (doctor + paramedic. Training is conducted outdoors at the base location all year round. The scenarios are led by scenario facilitators who are predominantly senior physicians. Their role is to brief the training team and guide the scenario, results of patient assessment and the simulated responses to interventions and treatment. Pilots, fire-fighters and medical students are utilised in scenarios to enhance realism by taking up roles as bystanders, additional ambulance staff and police. These scenario participants are briefed and introduced to the scene in a realistic manner. After completion of the scenario, the training team would usually be invited to prepare and deliver a hospital handover as they would in a real mission. A formal structured debrief then takes place. Results This training method technique has been used for the training of all London Helicopter Emergency Medical Service (London HEMS doctors and paramedics over the last 24 months. Informal participant feedback suggests that this is a very useful teaching method, both for improving motor skills, critical decision-making, scene management and team interaction. Although formal assessment of this technique has not yet taken place we describe how this type of training is conducted in a busy operational pre-hospital trauma service. Discussion The teaching and maintenance of pre-hospital care skills is essential to an effective pre-hospital trauma care system. Simple mannequin based scenario training is feasible on a day-to-day basis and has the advantages of low cost, rapid set up and turn around. The scope of scenarios is limited only by

    Full Text Available Abstract Background Evaluating geographic access to health services often requires determining the patient travel time to a specified service. For urgent care, many research studies have modeled patient pre-hospital time by ground emergency medical services (EMS using geographic information systems (GIS. The purpose of this study was to determine if the modeling assumptions proposed through prior United States (US studies are valid in a non-US context, and to use the resulting information to provide revised recommendations for modeling travel time using GIS in the absence of actual EMS trip data. Methods The study sample contained all emergency adult patient trips within the Calgary area for 2006. Each record included four components of pre-hospital time (activation, response, on-scene and transport interval. The actual activation and on-scene intervals were compared with those used in published models. The transport interval was calculated within GIS using the Network Analyst extension of Esri ArcGIS 10.0 and the response interval was derived using previously established methods. These GIS derived transport and response intervals were compared with the actual times using descriptive methods. We used the information acquired through the analysis of the EMS trip data to create an updated model that could be used to estimate travel time in the absence of actual EMS trip records. Results There were 29,765 complete EMS records for scene locations inside the city and 529 outside. The actual median on-scene intervals were longer than the average previously reported by 7–8 minutes. Actual EMS pre-hospital times across our study area were significantly higher than the estimated times modeled using GIS and the original travel time assumptions. Our updated model, although still underestimating the total pre-hospital time, more accurately represents the true pre-hospital time in our study area.

    Acute myocardial infarction ( AMI) is a dangerous disease with a high mortality rate. For AMI patients, the outcome of the patients depends on time to beginning of effective treatment in addition to other factors such as severity of disease and involved vessels etc. The key is whether reperfusion therapy is started early enough after the onset of symptoms, and the benefit of reperfu-sion therapy depends on the time, too. The delay of AMI treatment is divided into pre-hospital de-lay and in-hospital delay. In-hospital delay, Door-to-Balloon Time, has been well controlled. Pre-hospital delay, accounting for 75% of the total delay time, is the most important factor affect-ing AMI treatment. Patient delay ( PD) time for AMI patients is summarised in this study.

    Full Text Available Abstract Background Earthquakes are renowned as being amongst the most dangerous and destructive types of natural disasters. Iran, a developing country in Asia, is prone to earthquakes and is ranked as one of the most vulnerable countries in the world in this respect. The medical response in disasters is accompanied by managerial, logistic, technical, and medical challenges being also the case in the Bam earthquake in Iran. Our objective was to explore the medical response to the Bam earthquake with specific emphasis on pre-hospital medical management during the first days. Methods The study was performed in 2008; an interview based qualitative study using content analysis. We conducted nineteen interviews with experts and managers responsible for responding to the Bam earthquake, including pre-hospital emergency medical services, the Red Crescent, and Universities of Medical Sciences. The selection of participants was determined by using a purposeful sampling method. Sample size was given by data saturation. Results The pre-hospital medical service was divided into three categories; triage, emergency medical care and transportation, each category in turn was identified into facilitators and obstacles. The obstacles identified were absence of a structured disaster plan, absence of standardized medical teams, and shortage of resources. The army and skilled medical volunteers were identified as facilitators. Conclusions The most compelling, and at the same time amenable obstacle, was the lack of a disaster management plan. It was evident that implementing a comprehensive plan would not only save lives but decrease suffering and enable an effective praxis of the available resources at pre-hospital and hospital levels.

    Administering intravenous recombinant tissue plasminogen activator (r-tPA) within 4.5 h or endovascular procedures within 8 h of ischemic stroke onset may reduce the risk of disability. The effectiveness of media campaigns to raise stroke awareness and shorten pre-hospital delay is unclear. We studied 1144 consecutive ischemic stroke patients at Aomori Prefectural Central Hospital, Japan, between March 2010 and February 2014. From March 2012, the government sponsored an educational campaign based on a television commercial to improve knowledge of stroke symptoms and encourage ambulance calls for facial palsy, arm palsy, or speech disturbance. For the 544 and 600 patients admitted before and during the intervention, respectively, we recorded the National Institutes of Health Stroke Scale score, stroke type, the time when patients or bystanders recognized stroke symptoms, and hospital arrival time. Pre-hospital delay, as the time interval from awareness of stroke to hospital arrival, was categorized as 0-3, 3-6, and 6+ h. The mean pre-hospital delay was shorter (12.0 vs 13.5 h; P = 0.0067), the proportion of patients arriving within 3 h was larger (55.7 vs 46.5 %; P = 0.0021), and the proportion arriving after 6 h was smaller (32.7 vs 39.5 %; P = 0.0162) in the intervention group than in the pre-intervention group. There was no significant difference in the proportion of patients treated with r-tPA (6 and 7.5 % of the intervention and pre-intervention groups, respectively). A television-based public education campaign potentially reduced pre-hospital delay for ischemic stroke patients, but the r-tPA treatment rate was unchanged.

    Full Text Available Background: Achieving definitive care within the "Golden Hour" by minimizing response times is a consistent goal of regional trauma systems . This study hypothesizes that in urban Level I Trauma Centers, shorter pre-hospital times would predict outcomes in penetrating thoracic injuries. Materials and Methods: A retrospective cohort study was performed using a statewide trauma registry for the years 1999-2003 . Total pre-hospital times were measured for urban victims of penetrating thoracic trauma. Crude and adjusted mortality rates were compared by pre-hospital time using STATA statistical software. Results: During the study period, 908 patients presented to the hospital after penetrating thoracic trauma, with 79% surviving . Patients with higher injury severity scores (ISS were transported more quickly. Injury severity scores (ISS ≥16 and emergency department (ED hypotension (systolic blood pressure, SBP <90 strongly predicted mortality (P < 0.05 for each . In a logistic regression model including age, race, and ISS, longer transport times for hypotensive patients were associated with higher mortality rates (all P values <0.05. This was seen most significantly when comparing patient transport times 0-15 min and 46-60 min (P < 0.001. Conclusion: In victims of penetrating thoracic trauma, more severely injured patients arrive at urban trauma centers sooner . Mortality is strongly predicted by injury severity, although shorter pre-hospital times are associated with improved survival . These results suggest that careful planning to optimize transport time-encompassing hospital capacity and existing resources, traffic patterns, and trauma incident densities may be beneficial in areas with a high burden of penetrating trauma.

    2008-01-01

    INTRODUCTION Pleural drainage with chest tube insertion for thoracic trauma is a common and often life-saving technique. Although considered a simple procedure, complication rates have been reported to be 2–25%. We conducted a prospective cohort observational study of emergency pleural drainage procedures to validate the indications for pre-hospital thoracostomy and to identify complications from both pre- and in-hospital thoracostomies. PATIENTS AND METHODS Data were collected over a 7-month period on all patients receiving either pre-hospital thoracostomy or emergency department tube thoracostomy. Outcome measures were appropriate indications, errors in tube placement and subsequent complications. RESULTS Ninety-one chest tubes were placed into 52 patients. Sixty-five thoracostomies were performed in the field without chest tube placement. Twenty-six procedures were performed following emergency department identification of thoracic injury. Of the 65 pre-hospital thoracostomies, 40 (61%) were for appropriate indications of suspected tension pneumothorax or a low output state. The overall complication rate was 14% of which 9% were classified as major and three patients required surgical intervention. Twenty-eight (31%) chest tubes were poorly positioned and 15 (17%) of these required repositioning. CONCLUSIONS Pleural drainage techniques may be complicated and have the potential to cause life-threatening injury. Pre-hospital thoracostomies have the same potential risks as in-hospital procedures and attention must be paid to insertion techniques under difficult scene conditions. In-hospital chest tube placement complication rates remain uncomfortably high, and attention must be placed on training and assessment of staff in this basic procedure. PMID:18201502

    Endotracheal intubation is an important part of pre-hospital advanced life support that requires training and experience, and should only be performed by specially trained personnel. In Norway, anaesthesiologists serve as Helicopter Emergency Medical Service HEMS physicians. However, little is known about how they themselves evaluate the quality and safety of pre-hospital advanced airway management. Using a semi-structured questionnaire, we interviewed anaesthesiologists working in the three HEMS programs covering Western Norway. We compared answers from specialists and non-specialists as well as full- and part-time HEMS physicians. Of the 17 available respondents, most (88%) felt that their continuous exposure to intubations was not sufficient. Additional training was mainly acquired through other clinical practice and mannequin- or cadaver-based skills training. Of the respondents, 77% and 35% reported having experienced difficult and failed intubations, respectively. Further, 59% reported knowledge of airway management-related deaths in their HEMS program. Significantly more full- than part-time HEMS physicians had experienced these problems. All respondents had airway back-up equipment in their service, but 29% were not familiar with all the equipment. The majority of anaesthesiologists working as HEMS physicians view pre-hospital advanced airway management as a high-risk procedure. Relevant airway management competencies for HEMS physicians in Norway seem to be insufficiently trained and maintained. A better-defined level of competence with better training methods and systems seems warranted.

    The aim of this study was to explore the impact of motion generated by ambulance patient management on the performance of two lightweight physiologic sensors. Two physiologic sensors were applied to pre-hospital patients. The first was the Contec Medical Systems CMS50FW finger pulse oximeter, monitoring heart rate (HR) and blood oxygen saturation (SpO2). The second was the RESpeck respiratory rate (RR) sensor, which was wireless-enabled with a Bluetooth(®) Low Energy protocol. Sensor data were recorded from 16 pre-hospital patients, who were monitored for 21.2 ± 9.8 min, on average. Some form of error was identified on almost every HR and SpO2 trace. However, the mean proportion of each trace exhibiting error was ambulance transit on the incidence of HR or SpO2 error. The RESpeck RR sensor delivered an average of 4.2 (±2.2) validated breaths per minute, but did not produce any validated breaths during the gross motion of ambulance transit as its pre-defined motion threshold was exceeded. However, this was many more data points than could be achieved using traditional manual assessment of RR. Error was identified on a majority of pre-hospital physiologic signals, which emphasised the need to ensure consistent sensor attachment in this unstable and unpredictable environment, and in developing intelligent methods of screening out such error.

    Full Text Available BACKGROUND AND PURPOSE: Measures of specific knowledge of coping with pre-hospital stroke symptoms can help educate high-risk patients and family caregivers. This study aimed to develop and validate the Pre-hospital Stroke Symptoms Coping Test (PSSCT. MATERIALS AND METHODS: Reliability and validity were analyzed using multiple data sources. The Delphi expert consultation method was applied to assess the test's surface validity and content validity index. The final edition of the 19-item PSSCT contained 3 sections assessing coping with typical symptoms and symptoms associated with vomiting and twitching. Its psychometric properties were investigated in a community sample of 300 high-risk patients and family members. RESULTS: The PSSCT was readily accepted by participants. It demonstrated adequate surface validity and content validity, and good internal consistency (KR20 = 0.822 and test-retest reliability (0.769, with difficulty (P and degree of differentiation (D ranges of 0.28-0.83 and 0.15-0.66, respectively. It was also able to distinguish between individuals who had/had not experienced a stroke. Experienced individuals scored significantly higher overall and on coping with typical symptoms and twitching (P<0.01. CONCLUSIONS: The PSSCT can practically and directly assess critical knowledge regarding coping with pre-hospital stroke symptoms and has good reliability and validity.

    Background: Pre-hospital providers, such as paramedics and emergency medical technicians, are in a position to provide key emotional support to injured children and their families. Objective: Our goal was to examine (a) pre-hospital providers' knowledge of traumatic stress in children, attitudes towards psychosocial aspects of care, and confidence in providing psychosocial care, (b) variations in knowledge, attitudes, and confidence according to demographic and professional characteristics, and (c) training preferences of pre-hospital providers regarding psychosocial care to support paediatric patients and their families. Method: We conducted a cross-sectional, online survey among an international sample of 812 pre-hospital providers from high-income countries. The questionnaire was adapted from a measure for a similar study among Emergency Department staff, and involved 62 items in 7 main categories (e.g. personal and work characteristics, knowledge of paediatric traumatic stress, and confidence regarding 18 elements of psychosocial care). The main analyses comprised descriptive statistics and multiple regression analyses. Results: On average, respondents answered 2.7 (SD = 1.59) out of seven knowledge questions correctly. Respondents with higher knowledge scores were more often female, parent of a child under 17, and reported that at least 10% of their patients were children. A majority of participants (83.5%) saw all 18 aspects of psychosocial care as part of their job. Providers felt moderately confident (M = 3.2, SD = 0.45) regarding their skills in psychosocial care, which was predicted by gender (female), having more experience, having a larger proportion of child patients, and having received training in psychosocial care in the past five years. Most respondents (89.7%) wanted to gain more knowledge and skills regarding psychosocial care for injured children. In terms of training format, they preferred an interactive website or a one-off group

    Seizures are a common presentation to pre-hospital emergency services and they generate significant healthcare costs. This article summarises the United Kingdom (UK) Ambulance Service guidelines for the management of seizures and explores the extent to which these guidelines are evidence-based. Summary of the Clinical Practice Guidelines of the UK Joint Royal Colleges Ambulance Liaison Committee relating to the management of seizures. Review of the literature relating to pre-hospital management of seizure emergencies. Much standard practice relating to the emergency out of hospital management of patients with seizures is drawn from generic Advanced Life Support (ALS) guidelines although many patients do not need ALS during or after a seizure and the benefit of many ALS interventions in seizure patients remains to be established. The majority of studies identified pertain to medical treatment of status epilepticus. These papers show that benzodiazepines are safe and effective but it is not possible to draw definitive conclusions about the best medication or the optimal route of administration. The evidence base for current pre-hospital guidelines for seizure emergencies is incomplete. A large proportion of patients are transported to hospital after a seizure but many of these may be suitable for home management. However, there is very little research into alternative care pathways or criteria that could be used to help paramedics avoid transport to hospital. More research is needed to improve care for people after a seizure and to improve the cost-effectiveness of the healthcare systems within which they are treated.

    This paper describes a comparative study of the gravimetric versus hydrolysis/derivatization/gas chromatography-mass spectrometry determination of fat in infant formula. Fat was extracted using supercritical carbon dioxide modified with a small amount of ethanol, the extract was weighed, and the total fat was determined gravimetrically. Subsequently, another sample of the supercritical fluid fat extract was hydrolyzed to yield free fatty acids, which were converted to their methyl ester derivatives (FAMEs). Quantification was performed by GC-MS. NIST Standard Reference Material (SRM-1846) was used to validate both fat determination methods. Results showed that the gravimetric average percent fat was 26.86%, whereas the GC-MS method yielded 24.64%. Some peaks were detected in the ion chromatogram from the GC-MS that were identified as nonfatty acids such as aldehydes, which may account for the higher percentage fat measured as weight of extract rather than measured as FAMEs expressed as triglycerides.

Items that obtained adequate K and CVI indexes and remained in the instrument were: ambulance conservation status; physical structure; comfort in the ambulance; availability of material resources; user/staff safety; continuous learning; safety demonstrated by the team; access; welcoming; humanization; response time; costumer privacy; guidelines on care; relationship between professionals and costumers; opportunity for costumers to make complaints and multiprofessional conjunction/actuation. CONCLUSION The instrument to assess quality of care has been validated and may contribute to the evaluation of pre-hospital care in mobile emergency services.

    The pre-hospital and early in-hospital management of most severely injured patients has dramatically changed over the last 20 years. In this context, the factor time has gained more and more attention, particularly in German-speaking countries. While the management in the early 1990s aimed at comprehensive and complete therapy at the accident site, the premise today is to stabilise trauma patients at the accident site and transfer them into the hospital rapidly. In addition, the introduction of training and education programmes such as Pre-hospital Trauma Life Support (PHTLS(®)), Advanced Trauma Life Support (ATLS(®)) concept or the TEAM(®) concept has increased the quality of treatment of most severely injured trauma patients both in the preclinical field and in the emergency trauma room. Today, all emergency surgical procedures in severely injured patients are generally performed in accordance with the Damage Control Orthopaedics (DCO) principle. The advancements described in this article provide examples for the improved quality of the management of severely injured patients in the preclinical field and during the initial in-hospital treatment phase. The implementation of trauma networks, the release of the S3 polytrauma guidelines, and the DGU "Weißbuch" have contributed to a more structured management of most severely injured patients.

    India currently has the dubious distinction of experiencing the highest number of road traffic accidents in the world. We believe that this study on road traffic accidents may help to identify factors in the pre-hospital setting that may influence mortality rates. A prospective observational study was carried out in a metro area in India over a period of one year. The study included consecutive patients admitted to the trauma service after road traffic accidents. Demographic information, time and place of accident, and details regarding the vehicle and the events leading up to the hospital admission were recorded. Injury severity, management in the hospital, and final outcomes in terms of mortality were noted. The data were analyzed with SPSS software. A total of 773 patients were enrolled. Of these, there were 197 deaths and 576 survivors. The majority of patients were aged 15 - 40 years (67%) and were male (87.84%). More accidents occurred at night (58.2%) than during the day (41.8%). Mortality was not significantly associated with age, sex, or time of accident. City roads (38.9%) saw more accidents than highways (26.13%), but highway accidents were more likely to be fatal. Two-wheeler riders (37.65%) and pedestrians (35.75%) formed the majority of our study population. Mortality was significantly associated with crossing the road on foot (P = 0.004). Pillion riders on two-wheeler vehicles were more likely to experience poor outcomes (relative risk [RR] = 1.9, P = 0.001). Front-seat occupants in four-wheeler vehicles were at an increased risk of not surviving the accident (61.98%; RR=2.56, P = 0.01). Lack of safety gear, such as helmets, seat belts, and airbags, was significantly associated with mortality (P = 0.05). Delays in transfers of patients to the hospital and a lack of pre-hospital emergency services was significantly associated with increased mortality (P = 0.000). A lack of respect for the law, weak legislation and law enforcement, disregard for

    This short report describes the case of a young adult male who had smoked a synthetic cannabinoid legal high product called 'Exodus Damnation'. The patient's presentation was atypical from that described in the literature, with hypotension and hypoxaemia. Of note was the rapid recovery after pre-hospital intervention with high-flow oxygen therapy and intravenous fluids. The patient refused on-going care, despite repeated advice to attend the Emergency Department. The distinct lack of specialist support and referral to drug treatment for this patient population, with whom ambulance services are coming into contact with increasing frequency, is reported. For those patients with the capacity to refuse on-going care, ambulance services may be in an opportune position to actively promote referral to support services for these vulnerable individuals.

    The patient handover is important for the safe transition from the pre-hospital setting to secondary care. The loss of critical information about the pre-hospital phase may impact upon the clinical course of the patient. University Hospital Emergency Care registrars answered a questionnaire about how they perceive clinical documentation from the ambulance services. We also reviewed patient records retrospectively, to investigate to what extent eight selected parameters were transferred correctly to hospital records by clinicians. Only parameters outside the normal range were selected. The registrars preferred a verbal handover with hand-written pre-hospital reports as the combined source of clinical information. Scanned report forms were infrequently used. Information from other doctors was perceived as more important than the information from ambulance crews. Less than half of the selected parameters in pre-hospital notes were transferred to hospital records, even for parameters regarded as important by the registrars. Abnormal vital signs were not transferred as often as mechanism of injury, medication administered and immobilisation of trauma patients. Data on pre-hospital abnormal vital signs are frequently not transferred to the hospital admission notes. This information loss may lead to suboptimal care.

    Full Text Available Abstract Background Physician-manned emergency medical teams supplement other emergency medical services in some countries. These teams are often selectively deployed to patients who are considered likely to require critical care treatment in the pre-hospital phase. The evidence base for guidelines for pre-hospital triage and immediate medical care is often poor. We used a recognised consensus methodology to define key priority areas for research within the subfield of physician-provided pre-hospital critical care. Methods A European expert panel participated in a consensus process based upon a four-stage modified nominal group technique that included a consensus meeting. Results The expert panel concluded that the five most important areas for further research in the field of physician-based pre-hospital critical care were the following: Appropriate staffing and training in pre-hospital critical care and the effect on outcomes, advanced airway management in pre-hospital care, definition of time windows for key critical interventions which are indicated in the pre-hospital phase of care, the role of pre-hospital ultrasound and dispatch criteria for pre-hospital critical care services. Conclusion A modified nominal group technique was successfully used by a European expert group to reach consensus on the most important research priorities in physician-provided pre-hospital critical care.

    Ischaemic stroke clinical outcomes are improved by earlier treatment with intravenous thrombolysis. An existing pathway at the Mater University Hospital for assessment of suspected acute stroke in the Emergency Department was updated, aiming to shorten ‘door to needle time’. This study examines the final clinical diagnosis of Dublin Fire Brigade Ambulance Paramedic identified Face Arm Speech Test (FAST) positive patients presenting to the Emergency Department over a 7 month period. A retrospective analysis was carried out of 177 consecutive FAST positive patients presenting between March and November 2014. The final clinical diagnosis was acute stroke in 57.1% (n=101) of patients. Of these, 76 were ischaemic strokes of whom 56.5% (n=43) were thrombolysed. In the pre-hospital setting Ambulance Paramedics can identify, with reasonable accuracy, acute stroke using the FAST test. Over half of the ischaemic stroke patients presenting via this pathway can be treated with intravenous thrombolysis

    Full Text Available Pre-hospital trauma treatment is an important situation in which pain should be appropriately assessed and treated, but there is a great lack of studies about it. Literature has widely pointed out that the underanalgesia problem is spread to all groups of patients. The objective of the study is to verify the efficacy of a sedation-analgesia protocol based on the use of NSAIDs, Fentanyl and Midazolam, for prehospital treatment of trauma patients. The protocol was tested in three Emergency Medical Services for a four month period, in which 30 patients were included in the study. Results evidenced a good management of both pain and anxiety in the majority of patients treated, with the achievement of analgesia target in 80% of the patients and sedation target in 100% of the patients.

    Emergency medical research is subject to special conditions. Emergency patients e.g. are generally considered to be non-capable of giving consent. This results in sparse emergency medical data when compared to clinical observation studies under controlled conditions. After emergency medical treatment, deceased patients are not rarely subject to forensic investigation. The cooperation between emergency and forensic medicine has not only emergency medical training potential in individual cases, but also scientific innovation potential especially with respect to the retrospective evaluation of pre-hospital emergency measures. Such partnerships (like in Berlin at the Charité - Universitätsmedizin Berlin between the Institute of Legal Medicine and the Center for Musculoskeletal Surgery or in Hamburg between the Institute for Legal Medicine at the University Hospital and the Municipal Fire Brigade with the Emergency Medical Service) are yet exceptional in Germany. © Georg Thieme Verlag Stuttgart · New York.

    The Scandinavian society of anaesthesiology and intensive care medicine task force on pre-hospital airway management was asked to formulate recommendations following standards for trustworthy clinical practice guidelines. The literature was systematically reviewed and the grading of recommendations assessment, development and evaluation (GRADE) system was applied to move from evidence to recommendations. We recommend that all emergency medical service (EMS) providers consider to: apply basic airway manoeuvres and airway adjuncts (good practice recommendation); turn unconscious non-trauma patients into the recovery position when advanced airway management is unavailable (good practice recommendation); turn unconscious trauma patients to the lateral trauma position while maintaining spinal alignment when advanced airway management is unavailable [strong recommendation, low quality of evidence (QoE)]. We suggest that intermediately trained providers use a supraglottic airway device (SAD) or basic airway manoeuvres on patients in cardiac arrest (weak recommendation, low QoE). We recommend that advanced trained providers consider using an SAD in selected indications or as a rescue device after failed endotracheal intubation (ETI) (good practice recommendation). We recommend that ETI should only be performed by advanced trained providers (strong recommendation, low QoE). We suggest that videolaryngoscopy is considered for ETI when direct laryngoscopy fails or is expected to be difficult (weak recommendation, low QoE). We suggest that advanced trained providers apply cricothyroidotomy in 'cannot intubate, cannot ventilate' situations (weak recommendation, low QoE). This guideline for pre-hospital airway management includes a combination of techniques applied in a stepwise fashion appropriate to patient clinical status and provider training. © 2016 The Authors.

    Full Text Available Abstract Objectives Pre-hospital care (PH in Brazil is currently in the phase of implementation and expansion, and there are few studies on the impacts of this public health service. The purpose of this study is to assess the quality of care and severity of trauma among the population served, using trauma scores, attendance response times, and mortality rates. This work compares two pre-hospital systems: the Mobile Emergency Care Service, or SAMU 192, and the Fire Brigade Group, or CB. Method Descriptive study evaluating all patients transported by both systems in Catanduva, SP, admitted to a single hospital. Results 850 patients were included, most of whom were men (67.5%; the mean age was 38.5 ± 18.5 years. Regarding the use of PH systems, most patients were transported by SAMU (62.1%. The trauma mechanisms involved motorcycle accidents in 32.7% of cases, transferred predominantly by SAMU, followed by falls (25.8%. Regarding the response time, CB showed the lowest rates. In relation to patient outcome, only 15.5% required hospitalization. The average score on the Glasgow Coma Scale was 14.7 ± 1.3; average RTS was 7.7 ± 0.7; ISS 3.8 ± 5.9; and average TRISS 97.6 ± 9.3. The data analysis showed no statistical differences in mortality between the groups studied (SAMU - 1.5%; CB - 2.5%. The trauma scores showed a higher severity of trauma among the fatal victims. Conclusion Trauma victims are predominantly young and male; the trauma mechanism that accounted for the majority of PH cases was motorcycle accidents; CB responded more quickly than SAMU; and there was no statistical difference between the services of SAMU and CB in terms of severity of the trauma and mortality rates.

    Objective There has been very little use of telehealth in pre-hospital emergency medical services (EMS), yet the potential exists for this technology to transform the current delivery model. In this study, we explore the costs and benefits of one large telehealth EMS initiative. Methods Using a case-control study design and both micro- and gross-costing data from the Houston Fire Department EMS electronic patient care record system, we conducted a cost-benefit analysis (CBA) comparing costs with potential savings associated with patients treated through a telehealth-enabled intervention. The intervention consisted of telehealth-based consultation between the 911 patient and an EMS physician, to evaluate and triage the necessity for patient transport to a hospital emergency department (ED). Patients with non-urgent, primary care-related conditions were then scheduled and transported by alternative means to an affiliated primary care clinic. We measured CBA as both total cost savings and cost per ED visit averted, in US Dollars ($USD). Results In total, 5570 patients were treated over the first full 12 months with a telehealth-enabled care model. We found a 6.7% absolute reduction in potentially medically unnecessary ED visits, and a 44-minute reduction in total ambulance back-in-service times. The average cost for a telehealth patient was $167, which was a statistically significantly $103 less than the control group ( p cost savings from the societal perspective, or $2468 cost savings per ED visit averted (benefit). Conclusion Patient care enabled by telehealth in a pre-hospital environment, is a more cost effective alternative compared to the traditional EMS 'treat and transport to ED' model.

    To determine the optimal composition o f the pre-hospital medical response team (MERT) and the value of pre-hospital critical care interventions in a military setting, and specifically to determine both the benefit of including a doctor in the pre-hospital response team and the relevance of the time and distance to definitive care. A comprehensive review of the literature incorporating a range of electronic search engines and hand searches of key journals. There was no level 1 evidence on which to base conclusions. The 15 most relevant articles were analysed in detail. There was one randomized controlled trial (level 2 evidence) that supports the inclusion of a doctor on MERT. Several cohort studies were identified that analysed the benefits of specific critical care interventions in the pre-hospital setting. A doctor with critical care skills deployed on the MERT is associated with improved survival in victims of major trauma. Specific critical care interventions including emergency endotracheal intubation and ventilation, and intercostal drainage are associated with improved survival and functional recovery in certain patients. These benefits appear to be more easily demonstrated for the rural and remote setting than for the urban setting.

    Full Text Available Abstract Background: Iran is one of the countries with considerable road traffic injuries. Pre-hospital interventions have an important role in preventing mortalities and disabilities caused by traffic accidents.The present study aimed to explore the barriers of pre-hospital care in traffic injuries in Tehran, Iran. Methods: A qualitative content analysis approach was conducted based on 21 semi-structured interviews with 18 participants. A purposeful sampling method was applied until reaching data saturation. Interviews were transcribed verbatim, and then data condensing, labeling, coding and defining categories were performed by qualitative content analysis. Results: Four main barriers including 4 main categories and 13 subcategories emerged; they included Barriers related to people, Barriers related to metropolitan infrastructure,Barriers related to the profession and Barriers related to managerial issues. Conclusion: Based on the findings of this study, pre-hospital service barriers in traffic accidents have many dimensions including cultural, structural and managerial domains. Policy makers in health system can use these findings to promote the quality of pre-hospital services, especially in the field of traffic injuries.

    With the introduction of regional trauma networks in England, ambulance clinicians have been required to make triage decisions relating to severity of injury, and appropriate destination for the patient, which may require 'bypassing' the nearest Emergency Department. A 'Trauma Unit Bypass Tool' is utilised in this process. The Major Trauma Triage tool smartphone application (App) is a digital representation of a tool, available for clinicians to use on their smartphone. Prior to disseminating the application, validity and performance against the existing paper-based tool was explored. A case-based study using clinical scenarios was conducted. Scenarios, with appropriate triage decisions, were agreed by an expert panel. Ambulance clinicians were assigned to either the paper-based tool or smartphone app group and asked to make a triage decision using the available information. The positive predictive value (PPV) of each tool was calculated. The PPV of the paper tool was 0.76 and 0.86 for the smartphone app. User comments were mainly positive for both tools with no negative comments relating to the smartphone app. The smartphone app version of the Trauma Unit Bypass Tool performs at least as well as the paper version and can be utilised safely by pre-hospital clinicians in supporting triage decisions relating to potential major trauma.

    2013-12-01

    To gather preferences for novel pre-hospital physiologic monitoring technologies from emergency rescue services. Qualitative semi-structured interviews and focus groups were conducted with three groups from UK Search and Rescue (SAR); (1) Extractors (e.g. SAR teams), (2) Transporters (personnel primarily responsible for casualty transport), and (3) Treaters (e.g. Emergency Department doctors). Three themes were defined; SAR casualty management, novel physiologic monitor potential, and physiologic monitor physical properties. Some SAR groups already employed physiologic monitoring but there was no consensus on which monitor(s) to carry or what to monitor and how frequently. Existing monitors also tended to be bulky and heavy and could be unreliable in an unstable environment or if the casualty was cold. Those performing monitoring tended to have only basic first-aid training, and their workload was often high particularly if there was more than one casualty. The potential benefits of employing a novel monitor were strategic and clinical; an opportunity for transmitting data off-scene in order to facilitate monitoring or generate advice (i.e. telemedicine) was also voiced. A range of more intuitive, physical properties was also raised (e.g. small/compact, lightweight). SAR-specific technology should be simple to operate by those with less medical training, which means that clinical data interpretation and presentation should be carefully considered. It would be beneficial if novel monitors carried out a majority of the interpretation, allowing rescuers to proceed with their priority task of removing the casualty to safety.

    As in many other developing countries, emergency medical services, especially pre-hospital emergency care, has long been neglected in Pakistan. Consequently, patients are brought to the emergency departments by relatives or bystanders in private cars, taxis or any other readily available mode of transportation. Ambulances, where they exist, have barely a stretcher and arrangements for oxygen supply. Modern emergency services are considered too costly for many countries. A model of pre-hospital emergency services, called Rescue 1122 and established in Punjab province of Pakistan, is presented. The system is supported by government funding and provides a quality service. The article describes the process of establishment of the service, the organisational structure, the scope of services and the role it is currently playing in the healthcare of the region it serves.

    Advanced airway management is a critical intervention that can harm the patient if performed poorly. The available literature on this subject is rich, but it is difficult to interpret due to a huge variability and poor definitions. Several initiatives from large organisations concerned with airway management have recently propagated the need for guidelines and standards in pre-hospital airway management. Following the path of other initiatives to establish templates for uniform data reporting, like the many Utstein-style templates, we initiated and carried out a structured consensus process with international experts to establish a set of core data points to be documented and reported in cases of advanced pre-hospital airway management. A four-step modified nominal group technique process was employed. The inclusion criterion for the template was defined as any patient for whom the insertion of an advanced airway device or ventilation was attempted. The data points were divided into three groups based on their relationship to the intervention, including system-, patient-, and post-intervention variables, and the expert group agreed on a total of 23 core data points. Additionally, the group defined 19 optional variables for which a consensus could not be achieved or the data were considered as valuable but not essential. We successfully developed an Utstein-style template for documenting and reporting pre-hospital airway management. The core dataset for this template should be included in future studies on pre-hospital airway management to produce comparable data across systems and patient populations and will be implemented in systems that are influenced by the expert panel.

    A number of authors have shown how medical decisions are influenced by social values; others have minimized the putative influence of values and have argued that medical decisions are predominantly constrained by the organization of medical work. Based on fieldwork in France and the USA observing pre-hospital resuscitations, we seek to resolve these views by showing that while judgments about the social value of a patient do influence professional decisions, so do judgments about the work that must be accomplished to manage a case. Pre-hospital emergency work has many facets that are variably valued by different professionals at different moments of an emergency's trajectory. These values compete with each other in what we call a "fluctuating economy". This article analyses the role of social, technical, medical or surgical, heroic, and competence values in the course of pre-hospital emergency work. We show how these values may conflict or align with each other, forcing professionals to constantly establish priorities during an emergency trajectory.

    Optimal pre-hospital care for out-of-hospital cardiac arrest (OHCA) caused by respiratory disease may differ from that for OHCA associated with other aetiologies, especially with respect to respiratory management. We aimed to investigate whether pre-hospital advanced airway management (AAM) was associated with favourable outcomes after OHCA caused by intrinsic respiratory disease. This nationwide, population-based, propensity score-matched study of adult patients in Japan with OHCA due to respiratory disease from 1 January 2005 to 31 December 2012 compared patients with and without pre-hospital AAM. The primary outcome was neurologically favourable survival at one month after the OHCA. Of 49,534 eligible patients, 20,458 received pre-hospital AAM and 29,076 did not. In a propensity score-matched cohort (18,483 versus 18,483 patients), the odds of neurologically favourable survival were significantly lower for patients receiving pre-hospital AAM (0.6% versus 1.5%; odds ratio [OR] 0.42 [95% confidence interval {CI} 0.34 to 0.52]). The results from multivariable logistic regression analysis also showed that pre-hospital AAM was significantly associated with a decreased chance of neurologically favourable survival (adjusted OR 0.43 [95% CI 0.35 to 0.52]). Similar findings were observed for one-month survival and pre-hospital return of spontaneous circulation. In subgroup analyses, pre-hospital AAM was associated with poor neurological outcomes, regardless of the type of airway device used (laryngeal mask airway, adjusted OR 0.35 [95% CI 0.19 to 0.57]; oesophageal obturator airway, adjusted OR 0.44 [95% CI 0.35 to 0.55]; and endotracheal tube, adjusted OR 0.47 [95% CI 0.30 to 0.69]). In conclusion, pre-hospital AAM was associated with poor neurological outcome among patients with OHCA caused by intrinsic respiratory disease.

    The number of ambulance call-outs in Norway is increasing owing to societal changes and increased demand from the public. Together with improved but more expensive education of ambulance staff, this leads to increased costs and staffing shortages. We wanted to study whether the current dispatch triage tools could reliably identify patients who only required transport, and not pre-hospital medical care. This could allow selection of such patients for designated transport units, freeing up highly trained ambulance staff to attend patients in greater need. A cross-sectional observational study was used, drawing on all electronic and paper records in our ambulance service from four random days in 2012. The patients were classified into acuity groups, based on Emergency Medical Dispatch codes, and pre-hospital interventions were extracted from the Patient Report Forms. Of the 1489 ambulance call-outs included in this study, 82 PRFs (5 %) were missing. A highly significant association was found between acuity group and recorded pre-hospital intervention (p ≤ 0.001). We found no correlation between gender, distance to hospital, age and pre-hospital interventions. Ambulances staffed by paramedics performed more interventions (234/917, 26 %) than those with emergency medical technicians (42/282, 15 %). The strongest predictor for needing pre-hospital interventions was found to be the emergency medical dispatch acuity descriptor. This study has demonstrated that the Norwegian dispatch system is able to correctly identify patients who do not need pre-hospital interventions. Patients with a low acuity code had a very low level of pre-hospital interventions. Evaluation of adherence to protocol in the Emergency Medical Dispatch is not possible due to the inherent need for medical experience in the triage process. This study validates the Norwegian dispatch tool (Norwegian index) as a predictor of patients who do not need pre-hospital interventions.

    The article presents a description and analysis of the implementation of a pre-hospital treatment system (SAMU) as part of the research project Diagnostic Analysis of the Implementation of a National Policy for the Reduction of Violence and Accidents. Implementation and organization of the SAMU service, together with the related materials, human resources, and equipment, was studied in five Brazilian State capitals with high morbidity and mortality rates from external causes: Curitiba (Paraná), Recife (Pernambuco), Brasília (Federal District), Rio de Janeiro, and Manaus (Amazonas). The study involved four phases, each developing exploratory and analytical cycles, combined with fieldwork, triangulating quantitative and qualitative data. Implementation of the pre-hospital treatment system is now a key health sector asset. Further necessary steps include: comprehensive legislation covering vehicles, personnel, and equipment; closer networking between mobile units and healthcare facilities; focus on information generated in this sub-system, thus facilitating planning; and maintaining and upgrading high qualifications for SAMU crews. The service is officially establishing, standardizing, and regulating a sub-system that is crucial for saving lives.

    This study was designed to explore the utilization and non-utilization of pre-hospital emergency care by migrants and non-migrants, and the factors that influence this behaviour. A cross-sectional representative German survey was conducted in a sample of 2.175 people, 295 of whom had a migration background. An additional sample of 50 people with Turkish migration background was conducted, partially in the Turkish language. Apart from socio-demographics, the utilization of emergency services and the reasons for non-utilization were assessed. Migrants had a higher utilization rate of pre-hospital emergency care (RR = 1.492) than non-migrants. Furthermore, migrants who were not born in Germany had a lower utilization rate (RR = 0.793) than migrants who were born in Germany. Regarding non-utilization, the most frequently stated reasons belonged to the categories initial misjudgment of the emergency situation and acting on one's own behalf, with the latter stated more frequently by migrants than by non-migrants. To prevent over-, under-, and lack of supply, it is necessary to transfer knowledge about the functioning of the medical emergency services, including first aid knowledge.

    Marike Alferink

    Full Text Available BACKGROUND: Delay in seeking treatment at the hospital is a major challenge in current Buruli ulcer control; it is associated with severe sequelae and functional limitations. Choosing alternative treatment and psychological, social and practical factors appear to influence delay. Objectives were to determine potential predictors for pre-hospital delay with Leventhal's commonsense model of illness representations, and to explore whether the type of available dominant treatment modality influenced individuals' perceptions about BU, and therefore, influenced pre-hospital delay. METHODOLOGY: 130 healthy individuals aged >18 years, living in BU-endemic areas in Benin without any history of BU were included in this cross-sectional study. Sixty four participants from areas where surgery was the dominant treatment and sixty six participants from areas where antibiotic treatment was the dominant treatment modality were recruited. Using a semi-structured interview we measured illness perceptions (IPQ-R, knowledge about BU, background variables and estimated pre-hospital delay. PRINCIPAL FINDINGS: The individual characteristics 'effectiveness of treatment' and 'timeline acute-chronic' showed the strongest association with pre-hospital delay. No differences were found between regions where surgery was the dominant treatment and regions where antibiotics were the dominant treatment modality. CONCLUSIONS: Individual characteristics, not anticipated treatment modality appeared predictors of pre-hospital delay.

    The aim of this systematic review was to determine the supporting evidence for the clinical use of hydrogel dressings as a first aid measure for burn wound management in the pre-hospital setting. Two authors searched three databases (Ovid Medline, Ovid Embase and The Cochrane Library) for relevant English language articles published through September 2014. Reference lists, conference proceedings and non-indexed academic journals were manually searched. A separate search was conducted using the Internet search engine Google to source additional studies from burns advisory agencies, first aid bodies, military institutions, manufacturer and paramedic websites. Two authors independently assessed study eligibility and relevance of non-traditional data forms for inclusion. Studies were independently assessed and included if Hydrogel-based burn dressings (HBD) were examined in first aid practices in the pre-hospital setting. A total of 129 studies were considered for inclusion, of which no pre-hospital studies were identified. The review highlights that current use of HBD in the pre-hospital setting appears to be driven by sources of information that do not reflect the paramedic environment. We recommend researchers in the pre-hospital settings undertake clinical trials in this field. More so, the review supports the need for expert consensus to identify key demographic, clinical and injury outcomes for clinicians and researchers undertaking further research into the use of dressings as a first aid measure.

    Full Text Available Background: Data on the prehospital interventions received by critically ill children at arrival to Paediatric Emergency Services (PES is limited in developing countries. This study aims to describe the pre-hospital care scenario, transport and their impact on outcome in non-traumatic, acutely ill children presenting in PES with agonal breathing. Methods: Prospective observational study done on children aged below 15 years arriving in PES with agonal breathing due to non-trauma related causes. Results: Out of 75 children studied, 69% were infants. The duration of illness among 65% of them (75 was less than 3 days. Majority of them (81% had received treatment prior to arrival. Government sector physicians (72%, half of them (51% being pediatricians were the major treating doctors. 37% of the children had arrived to the Emergency in an ambulance. Cardiopulmonary Resuscitation (CPR was given to 27% on arrival in PES. Other interventions included fluid boluses to correct shock (92% and inotrope infusion (56%. Sepsis (24% and pneumonia (24% were the most common diagnoses. Out of 75, 57 (76% children who were stabilized and shifted to PICU and among them 27 (47% survived to discharge. Normal blood pressure (p=0.0410 and non-requirement of CPR (0.0047 and inotropic infusion (0.0459 in PES were associated with a higher chance of survival. Conclusion: 36% (27/75 of children who arrived to our PES with agonal breathing survived to hospital discharge. Survival was significantly better among those who did not need CPR.

    Full Text Available This survey aims to encourage the multidisciplinary communities to join forces for innovation in the mobile health monitoring area. Specifically, multidisciplinary innovations in medical emergency scenarios can have a significant impact on the effectiveness and quality of the procedures and practices in the delivery of medical care. Wireless body sensor networks (WBSNs are a promising technology capable of improving the existing practices in condition assessment and care delivery for a patient in a medical emergency. This technology can also facilitate the early interventions of a specialist physician during the pre-hospital period. WBSNs make possible these early interventions by establishing remote communication links with video/audio support and by providing medical information such as vital signs, electrocardiograms, etc. in real time. This survey focuses on relevant issues needed to understand how to setup a WBSN for medical emergencies. These issues are: monitoring vital signs and video transmission, energy efficient protocols, scheduling, optimization and energy consumption on a WBSN.

    Full Text Available Abstract Background Road traffic injuries (RTIs are a major public health problem, requiring concerted efforts both for their prevention and a reduction of their consequences. Timely arrival of the Emergency Medical Service (EMS at the crash scene followed by speedy victim transportation by trained personnel may reduce the RTIs' consequences. The first 60 minutes after injury occurrence - referred to as the "golden hour"- are vital for the saving of lives. The present study was designed to estimate the average of various time intervals occurring during the pre-hospital care process and to examine the differences between these time intervals as regards RTIs on urban and interurban roads. Method A retrospective cross-sectional study was designed and various time intervals in relation to pre-hospital care of RTIs identified in the ambulance dispatch centre in Urmia, Iran from 20 March 2005 to 20 March 2007. All cases which resulted in ambulance dispatches were reviewed and those that had complete data on time intervals were analyzed. Results In total, the cases of 2027 RTI victims were analysed. Of these, 61.5 % of the subjects were injured in city areas. The mean response time for city locations was 5.0 minutes, compared with 10.6 minutes for interurban road locations. The mean on-scene time on the interurban roads was longer than on city roads (9.2 vs. 6.1 minutes, p Conclusion The response, transport and total time intervals among EMS responding to RTI incidents were longer for interurban roads, compared to the city areas. More research should take place on needs-to and access-for EMS on city and interurban roads. The notification interval seems to be a hidden part of the post-crash events and indirectly affects the "golden hour" for victim management and it needs to be measured through the establishment of the surveillance systems.

    2013-05-01

    Airway management is an important skill in pre-hospital emergency medicine. The most optimal method depends on the resources and experience of the emergency medical service (EMS) providers. We wanted to study the frequency of occurrence, equipment used, problems experienced and maintenance of skills in pre-hospital airway management by non-physicians. A structured questionnaire consisting of 30 questions was distributed to 383 EMS providers in three hospital districts (population 597,521 and area 147,467 km(2) ) in Northern Finland. The questionnaire was answered by 226 EMS providers and 58.5% (224/383) were included in the final analyses. In all, 82.6% (185/224) of the EMS providers were allowed to perform endotracheal intubation (ETI) and 44.2% (99/224) could perform ETI using sedative agents. The annual mean frequency of using a supraglottic airway device (SAD) was 1.0 (range 0-20, n = 224), for ETI it was 2.0 (range 0-16, n = 185) and for bag-valve-mask ventilation it was 4.3 (range 0-30, n = 223). The mean frequency of drug-assisted ETI was 1.1 (range 0-13, n = 99). Unsuccessful ETI had been experienced by 65.7% (119/181) of the EMS providers. Airway management had been practised in an operating room by 25.9% (56/216) and with a manikin by 81.3% (182/224) of the EMS providers during the past 12 months. Advanced airway management procedures are uncommon for most EMS providers in Northern Finland. Procedures, training in and maintenance of airway management skills should be re-evaluated. © 2013 The Acta Anaesthesiologica Scandinavica Foundation.

    Full Text Available Background: Snakebite is the most important cause of envenomation in South Asia particularly in Bangladesh, though there is lack of data from the rural part of the country. About 82 species of snakes (28 venomous exist in Bangladesh. In this study, demographic characteristics of the victim, circumstances behind the bite along with pre-hospital and hospital managements and outcomes were evaluated. Methods: It was a cross-sectional study during January 2010 to June 2012 at Rangpur Medical College Hospital. Only venomous snakebite cases were included and diagnosis was made on clinical syndrome. Descriptive statistics were presented using percentage and proportion. Results: Out of 28 patients (mean age: 31.7 years, 20 (71.4% were males with a significant male-female ratio (2.5:1. Majority were farmers (46.4% and most (50% of the bites happened during household activities. Lag period between bite and hospitalization was ≤5 hours in 50% patients; 6 to 10 hours in 39.2% and >10 hours in 10.7% cases. 82.1% patients received ligature as pre-hospital first aid. Total 21 patients received anti-snake venom (ASV in different dose regimens. 15 (53.5% patients recovered while 13 (46.4% died. Among 13 patients who died, 53.8% died within 2 hours, 15.3% within 3-24 hours and 30.7% after 24 hours post-bite. Conclusion: Snakebite has a significant impact on human health and economy through treatment-related expenditures and loss of productivity. Policy makers of Bangladesh should prioritize the issue to reduce future mortality and morbidity. Keywords: Poisoning, Snakebite, Bangladesh, Envenomation, Management

    During perioperative management of patients with gastrointestinal cancer complicated by diabetes mellitus, adequate alimentation is required, but we often face difficulties associated with hyperglycemia and other accompanying complications. Recently, we investigated the effects of a novel palatinose based enteral formula (MHN-01) in suppressing post-prandial hyperglycemia and improving lipid metabolism in experimental animals and perioperative management of patients with esophageal cancer complicated by diabetes mellitus. We gave normal rats and rats with type 2 diabetes mellitus a single oral dose of fluid diet, and analyzed comparatively the time course of blood glucose level in each group until 3 h after the dose. In both the normal rat group and the type 2 diabetes group, peak blood glucose level after the MHN-01 dose was significantly lower than after a dose of ordinary fluid diet and was comparable to the peak level after a dose of a fluid diet rich in MUFA (monounsaturated fatty acid). We allowed normal mice free access to fluid diet for 43 days, and measured their body fat levels. Fat accumulation was significantly lower in mice given MHN-01 than in mice given ordinary fluid diet. We also analyzed the respiratory quotient and resting energy expenditure of normal Sprague-Dawley rats fed by MHN-01 or an ordinary fluid diet. The respiratory quotient of the MHN-01 group was significantly lower than the ordinary fluid group, although the resting energy expenditure of both groups was almost the same level. The effect of MHN-01 was estimated to be based on improvement of lipid metabolism. Between 2003 and 2005, among 164 patients who underwent radical thoracic esophagectomy and/or reconstruction for esophageal carcinoma at Okayama University Hospital, nine patients (5.5%) were diagnosed with diabetes mellitus in pre-operative screening and were treated with MHN-01. Clinical courses of two cases with severe status of diabetes mellitus were presented as successful

    Background Every day throughout the UK, ambulance services seek medical assistance in providing critically ill or injured patients with pre-hospital care. Objective To identify the current availability and utilisation of physician-based pre-hospital critical care capability across England, Wales and Northern Ireland. Design A postal and telephone survey was undertaken between April and December 2009 of all 13 regional NHS ambulance services, 17 air ambulance charities, 34 organisations affiliated to the British Association for Immediate Care and 215 type 1 emergency departments in England, Wales and Northern Ireland. The survey focused on the availability and use of physician-based pre-hospital critical care support. Results The response rate was 100%. Although nine NHS ambulance services recorded physician attendance at 6155 incidents, few could quantify doctor availability and utilisation. All but one of the British Association for Immediate Care organisations deployed ‘only when available’ and only 45% of active doctors could provide critical care support. Eleven air ambulance services (65%) operated with a doctor but only 5 (29%) operated 7 days a week. Fifty-nine EDs (27%) had a pre-hospital team but only 5 (2%) had 24 h deployable critical care capability and none were used regularly. Conclusion There is wide geographical and diurnal variability in availability and utilisation of physician-based pre-hospital critical care support. Only London ambulance service has access to NHS-commissioned 24 h physician-based pre-hospital critical care support. Throughout the rest of the UK, extensive use is made of volunteer doctors and charity sector providers of varying availability and capability. PMID:21427108

    2013-10-01

    The development of the Swedish ambulance service has resulted in three different competence levels in Swedish ambulance teams: specialist ambulance nurses, registered nurses and emergency medical technicians. A nursing scientific model developed by Peplau (Peplau, H., 1991. Interpersonal Relations in Nursing. Springer Publishing Company, New York.) breaks down the nurse-patient relationship into a number of phases: an orientation, an identification, an exploitation and a resolution phase. This model has then been adapted to the pre-hospital emergency care by Suserud (Dahlberg, K., Segesten, K., Nyström, M., Suserud, B.-O., Fagerberg, I., 2003. Att förstå vårdvetenskap [To Understand Caring Science]. Studentlitteratur, Lund.). The purpose of this study was to explore, by direct content analysis, how the phases of the pre-hospital nurse-patient relationship described by Suserud (Dahlberg et al., 2003), emerge in 17 specialist ambulance nursing students descriptions of ambulance missions. The results show that the four phases of the pre-hospital nurse-patient relationship could be identified and each phase includes several different parts. Furthermore, the results show that the parts of each phase can vary depending on the patient's condition and the environmental circumstances of the ambulance mission. This improved understanding of the four phases of the pre-hospital nurse-patient relationship, and their parts, could be used by ambulance team members as a support during the pre-hospital caring process in ambulance missions. This new knowledge could also be used in education. Copyright © 2012 Elsevier Ltd. All rights reserved.

    Full Text Available Patients with ST elevation myocardial infarction (STEMI require prompt treatment, best done by primary percutaneous coronary intervention (PPCI. However, for patients unable to receive PPCI, immediate pre-hospital thrombolysis (PHT is the best alternative. Evidence indicates that diagnostic and management support for staff increases the use of PHT. This study aimed to describe the patient demographics and management of patients, to determine any potential inter-area differences in referral rates to the ECG e-transmission service and to explore the views and experiences of key staff involved in ECG e-transmission within NHS Highland. Data from 2,025 patient episodes of ECG e-transmission identified a statistically significant geographical variation in ECG e-transmission and PHT delivery. Scottish Ambulance Service (SAS staff were more likely than GPs to deliver PHT overall, however, GPs were more likely to deliver in remote areas. Interviews with six Cardiac Care Unit (CCU nurses and six SAS staff highlighted their positive views of ECG e-transmission, citing perceived benefits to patients and interprofessional relationships. Poor access to network signal was noted to be a barrier to engaging in the system. This study has demonstrated that a specialist triage service based on e-transmission of ECGs in patients with suspected STEMI can be implemented in a diverse geographical setting. Work is needed to ensure equity of the service for all patients.

    Full Text Available Snakebite is an important medical emergency. Anti-snake venom along with supportive care is the only specific treatment. However, many people put their faith in non-registered medical practitioners. Where medical aid is available, lack of trained health personnel jeopardizes the situation. This retrospective study, the first of its kind, was aimed at studying the pre-hospital treatment as well as the behavior of patients bitten by snakes and referred to the Postgraduate Institute of Medical Education and Research, Chandigarh, India. A total of 88 cases that occurred between January 1997 and December 2001 were studied. Seventy patients received treatment prior to admission (the majority was treated by non-registered medical practitioners, registered medical practitioners, and MBBS doctors. The various treatment modalities used were: anti-snake venom (ASV, tourniquet, incision and drainage (I&D, tetanus toxoid, injections, and tablets. Non-registered medical practitioners still preferred tourniquet and I&D. The patients who were referred within 24 hours stayed less time in the hospital and spent less money on the treatment compared to those who were referred after 24 hours. Non-registered medical practitioners and inadequately trained health staff are often the first contact of snakebite victims. Their traditional and unscientific methods of treatment lead to unnecessary morbidity and increased treatment cost. It is therefore necessary to train these people adequately so that proper treatment can be instituted at the earliest.

    This study evaluated the time performance in the emergency response center to provide pre-hospital emergency services in Kermanshah. This study was a descriptive retrospective cross-sectional study. In this study 500 cases of patients from Shahrivar (September) 2012 to the end of Shahrivar (September) 2013 were selected and studied by the non-probability quota method. The measuring tool included a preset cases record sheet and sampling method was completing the cases record sheet by referring to the patients' cases. Data were analyzed using SPSS version 18 and the concepts of descriptive and inferential statistics (Kruskal-Wallis test, benchmark Eta (Eta), Games-Howell post hoc test). The results showed that the interval mean between receiving the mission to reaching the scene, between reaching the scene to moving from the scene, and between moving from the scene to a health center was 7.28, 16.73 and 7.28 minutes. The overall mean of time performance from the scene to the health center was 11.34 minutes. Any intervention in order to speed up service delivery, reduce response times, ambulance equipment and facilities required for accuracy, validity and reliability of the data recorded in the emergency dispatch department, Continuing Education of ambulance staffs, the use of manpower with higher specialize levels such as nurses, supply the job satisfaction, and increase the coordination with other departments that are somehow involved in this process can provide the ground for reducing the loss and disability resulting from traffic accidents.

    2011-01-01

    Although tracheal intubation (TI) in the pre-hospital setting is regularly carried out by emergency medical service (EMS) providers throughout the world, its value is widely debated. Heterogeneity in procedures, providers, patients, systems and stated outcomes, and inconsistency in data reporting make scientific reports difficult to interpret and compare, and the majority are of limited quality. To hunt down what is really known about the value of pre-hospital TI, we determined the rate of reported Utstein airway variables (28 core variables and 12 fixed-system variables) found in current scientific publications on pre-hospital TI. We performed an all time systematic search according to the PRISMA guidelines of Medline and EMBASE to identify original research pertaining to pre-hospital TI in adult patients. From 1,076 identified records, 73 original papers were selected. Information was extracted according to an Utstein template for data reporting from in-the-field advanced airway management. Fifty-nine studies were from North American EMS systems. Of these, 46 (78%) described services in which non-physicians conducted TI. In 12 of the 13 non-North American EMS systems, physicians performed the pre-hospital TI. Overall, two were randomised controlled trials (RCTs), and 65 were observational studies. None of the studies presented the complete set of recommended Utstein airway variables. The median number of core variables reported was 10 (max 21, min 2, IQR 8-12), and the median number of fixed system variables was 5 (max 11, min 0, IQR 4-8). Among the most frequently reported variables were "patient category" and "service mission type", reported in 86% and 71% of the studies, respectively. Among the least-reported variables were "co-morbidity" and "type of available ventilator", both reported in 2% and 1% of the studies, respectively. Core data required for proper interpretation of results were frequently not recorded and reported in studies investigating TI in

    Full Text Available Abstract Background & Aims of the Study: When the issue of the quality of the patient's care is addressed, determination of infection degrees in reference to the quality of such cares has gained a high priority. Therefore, infections in ambulance equipment might play a significant role in reduction of the quality of the hospital cares. This study was conducted wishing to determine bacterial infection degrees in ambulances servicing in pre-hospital emergency medical services of Qom University of Medical Sciences, Iran. Materials and Methods: In this analytical cross-sectional study, 132 sampling of the equipments of 12 ambulances were done. Samples were stored on BHI broth as an amplifier for 24 hours. Then, they were introduced to blood agar and Eosin Methylene Blue (EMB agar culture environments. After 24 hours, negative staphylococcus coagulase and bacillus were specified by different environments, solutions, diagnostic discs, gram staining, catalase test, oxidase test and coagulase test. Then data were analyzed by SPSS16. Results: The results showed that the highest infection prevalence rate was observed in stretchers (12 samples, 100% and the lowest in oxygenation moisturizers (1 sample, 8.4%. From infected equipments, in addition, four instruments (37% were mobile and eight of them (63% were immobile. Conclusion: Results indicated that an infection degree of the utensils and instruments which were used in ambulances employed servicing in the Qom Province Medical Emergency Response Center of Iran is high, that might have their roots in non-application of disinfectants for disinfecting ambulance surfaces and equipment. This is a mandatory for healthcare agents to utilize the protective covers, especially medical gloves.

    Implementation of evidence-based treatment for pre-hospital status epilepticus can improve outcomes. We hypothesized that publication of a pivotal pre-hospital clinical trial (RAMPART), demonstrating superiority of intramuscular midazolam over intravenous lorazepam, altered the national utilization rates of midazolam for pre-hospital benzodiazepine-treated seizures, while upholding its safety and efficacy outside the trial setting. This is a retrospective, observational cohort study of pre-hospital patient encounters throughout the United States in the National Emergency Medicine Services Information System database, from January 2010 through December 2014. We compared the rates and odds of midazolam use as first-line treatment among all adult and pediatric benzodiazepine-treated seizures before and after RAMPART publication (February 2012). Secondary analyses were conducted for rates of airway interventions and rescue therapy, as proxies for safety and efficacy of seizure termination. 156,539 benzodiazepine-treated seizures were identified. Midazolam use increased from 26.1% in January 2010 to 61.7% in December 2014 (difference +35.6%, 95% CI, 32.7%-38.4%). The annual rate of midazolam adoption increased significantly from 5.9% per year to 8.9% per year after the publication of RAMPART (difference +3.0% per year; 95%CI, 1.6%-4.5% per year; adjusted OR 1.24; 95%CI, 1.17-1.32). Overall frequency of rescue therapy and airway interventions changed little after the publication of RAMPART. These data are consistent with effective, ongoing, but incomplete clinical translation of the RAMPART results. The effects of the trial, however, cannot be isolated. The study was limited by broad inclusion of all benzodiazepine-treated seizures as well as a lack of information on route of drug of administration. The safety and effectiveness of midazolam for benzodiazepine-treated seizures in prehospital clinical practice appear consistent with trial data, which should encourage

    2011-05-01

    Full Text Available Introduction: Acute anterior myocardial infarctions caused by proximal left anterior descending (LAD artery occlusions are associated with a higher morbidity and mortality. Early identification of high-risk patients via the 12-lead electrocardiogram (ECG could assist physicians and emergency response teams in providing early and aggressive care for patients with anterior ST-elevation myocardial infarctions (STEMI. Approximately 25% of US hospitals have primary percutaneous coronary intervention (PCI capability for the treatment of acute myocardial infarctions. Given the paucity of hospitals capable of PCI, early identification of more severe myocardial infarction may prompt emergency medical service routing of these patients to PCI-capable hospitals. We sought to determine if the 12 lead ECG is capable of predicting proximal LAD artery occlusions. Methods: In a retrospective, post-hoc analysis of the Pre-Hospital Administration of Thrombolytic Therapy with Urgent Culprit Artery Revascularization pilot trial, we compared the ECG findings of proximal and nonproximal LAD occlusions for patients who had undergone an ECG within 180 minutes of symptom onset. Results: In this study, 72 patients had anterior STEMIs, with ECGs performed within 180 minutes of symptom onset. In patients who had undergone ECGs within 60 minutes (n¼35, the mean sum of ST elevation (STE in leads V1 through V6 plus ST depression (STD in leads II, III, and aVF was 19.2 mm for proximal LAD occlusions and 11.7 mm for nonproximal LAD occlusions (P¼0.007. A sum STE in V1 through V6 plus STD in II, III, and aVF of at least 17.5 mm had a sensitivity of 52.3%, specificity of 92.9%, positive predictive value of 91.7%, and negative predictive value of 56.5% for proximal LAD occlusions. When the ECG was performed more than 60 minutes after symptom onset (n¼37, there was no significant difference in ST-segment deviation between the 2 groups. Conclusion: The sum STE (V1-V6 and STD (II

    Paramedics make important and increasingly complex decisions at scene about patient care. Patient safety implications of influences on decision making in the pre-hospital setting were previously under-researched. Cutting edge perspectives advocate exploring the whole system rather than individual influences on patient safety. Ethnography (the study of people and cultures) has been acknowledged as a suitable method for identifying health care issues as they occur within the natural context. In this paper we compare multiple methods used in a multi-site, qualitative study that aimed to identify system influences on decision making. The study was conducted in three NHS Ambulance Trusts in England and involved researchers from each Trust working alongside academic researchers. Exploratory interviews with key informants e.g. managers (n = 16) and document review provided contextual information. Between October 2012 and July 2013 researchers observed 34 paramedic shifts and ten paramedics provided additional accounts via audio-recorded 'digital diaries' (155 events). Three staff focus groups (total n = 21) and three service user focus groups (total n = 23) explored a range of experiences and perceptions. Data collection and analysis was carried out by academic and ambulance service researchers as well as service users. Workshops were held at each site to elicit feedback on the findings and facilitate prioritisation of issues identified. The use of a multi-method qualitative approach allowed cross-validation of important issues for ambulance service staff and service users. A key factor in successful implementation of the study was establishing good working relationships with academic and ambulance service teams. Enrolling at least one research lead at each site facilitated the recruitment process as well as study progress. Active involvement with the study allowed ambulance service researchers and service users to gain a better understanding of the research

    现代急救医学多分为院前急救和院内急救两部分,前者更是整个抢救体系中的重要部分。在抢救过程中,护理安全是决定急救质量的一项重要指标。其高低直接能造成最终患者的抢救结果。优秀的护理安全以及相应的细节管理目前越来越被医院以及医护人员所重视。本文通过对近年来国内医院护理安全和细节管理在院前急救中的实施情况进行了回顾,陈述当前护理安全细节管理在院前急救中的现状,以及其实际的应用前景。%Modern Emergency Medicine is normally divided as pre-hospital care and hospital care. The former one is a more important part in the whole emergency system. In the rescue process, nursing safety is an important indicator to decide rescue equality. Its level can directly influence the final rescue result. Now excellent nursing safety and relevant specific management are paid more and more attention by hospital and medical workers. This article reviewed the implementation of domestic hospital nursing safety and specific management in pre-hospital care in recent years, and stated current situation of nursing safety management in pre-hospital care and its practical application prospect.

    Full Text Available Abstract Background Early interventions proved to be able to improve prognosis in acute stroke patients. Prompt identification of symptoms, organised timely and efficient transportation towards appropriate facilities, become essential part of effective treatment. The implementation of an evidence based pre-hospital stroke care pathway may be a method for achieving the organizational standards required to grant appropriate care. We performed a systematic search for studies evaluating the effect of pre-hospital and emergency interventions for suspected stroke patients and we found that there seems to be only a few studies on the emergency field and none about implementation of clinical pathways. We will test the hypothesis that the adoption of emergency clinical pathway improves early diagnosis and referral in suspected stroke patients. We designed a cluster randomised controlled trial (C-RCT, the most powerful study design to assess the impact of complex interventions. The study was registered in the Current Controlled Trials Register: ISRCTN41456865 – Implementation of pre-hospital emergency pathway for stroke – a cluster randomised trial. Methods/design Two-arm cluster-randomised trial (C-RCT. 16 emergency services and 14 emergency rooms were randomised either to arm 1 (comprising a training module and administration of the guideline, or to arm 2 (no intervention, current practice.

We estimated that around 750 patients will be met by the services in the 6 months of observation. This duration allows recruiting a sample of patients sufficient to observe a 30% improvement in the proportion of appropriate diagnoses.

    Background Cumulative evidence demonstrates that primary percutaneous coronary intervention(PCI)is a mperfusion strategy for ST-elevation myocardial Infarction(STEMI).This study was undertaken to evaluate the pre-hospital care-seeking pathway and subsequent care quality in patients with STEMI in the Beijing health care system,which offers patients a choice between seeking care in a small community hospital(SH group)or a large hospital(LH group).Methods Between January 1 and December 31,2006, a cross-sectional and multicenter survey was conducted in 11 hospitals qualified as tertiary centers in Beijing and included consecutive patients with STEMI admitted within 24 hours after onset of symptoms.Results Among the 566 patients interviewed,28.3%first arnved at a small community hospitaI and were transferred to large hospitals with the ability to perform primary PCI.The median total pre-hospital delay in the SH group(n=160)was significantly longer than in the LH group(n=406)(225 vs.120 minutes,P<0.001).Multivariate analysis showed that interpreting symptoms to non-cardiac origin(OR,1.996;95%CI: 1.264-3.155),absence of history of myocardial infarction(OR,1.595;95%CI:1.086-3.347),non-health insuranca coverage(OR,1.931;95%Cl:1.079-3.012)and absence of sense of impending doom (OR,4.367;95%CI:1.279-1 4.925) were independent predictors for choosing small hospitals.After adjusting for demographics and medical history,patients in the SH group were 1.698 times(95% CI: 1.1 82-3.661) less likely to receive primary PCI compared with those in the LH group. Conclusions Above one fourth of the STEMI patients in Beijing experienced inter-hospital transfer.Factors including symptoms interpretation,symptoms,history of myocardial infarcUon,and insurance coverage were associated with the patients'pre-hospital care-seeking pathway.The patients who were transferred had longer pre-hospital delays and were less Iikely to receive primary PCI.

    Tuberculosis (TB) remains a major health problem in Zambia, despite considerable efforts to control and prevent it. With this study, we aim to understand how perceptions and cultural, social, economic, and organisational factors influence TB patients' pre-hospital delay and non-compliance with care provided by the National Tuberculosis Programme (NTP). A mixed methods study was conducted with 300 TB patients recruited at Kanyama clinic for structured interviews. Thirty were followed-up for multiple in-depth interviews. Six focus group discussions were organised and participant observation was conducted. Ten biomedical care providers, 10 traditional healers, and 10 faith healers were interviewed. Factors associated with non-compliance (disruption of treatment > one week) were assessed by applying logistic regression analyses; qualitative analysis was used to additionally assess factors influencing pre-hospital delay and for triangulation of study findings. TB treatment non-compliance was low (10 %), no association of outcome with cultural or socio-economic factors was found. Only patients' time constraints and long distance to the clinic indicated a possible association with a higher risk of non-compliance (OR 0.52; 95 % CI 0.25, 1.10, p = 0.086). Qualitative data showed that most TB patients combined understandings of biomedical and traditional TB knowledge, used herbal, traditional and/or faith healing, suffered from stigmatizing attitudes, experienced poverty and food shortages, and faced several organisational obstacles while being on treatment. This led in some cases to pre-hospital delay or treatment non-compliance. Mixed methods analysis demonstrated the importance of in-depth information ascertained by qualitative approaches to understand how cultural, socio-economic and organisational factors are influencing patients' pre-hospital delay and treatment compliance. To strengthen the Zambian NTP, combating stigma is of utmost priority coupled with

    The gastrointestinal microbiota of breast-fed babies differ from classic standard formula fed infants. While mother's milk is rich in prebiotic oligosaccharides and contains small amounts of probiotics, standard infant formula doesn't. Different prebiotic oligosaccharides are added to infant formula: galacto-oligosaccharides, fructo-oligosaccharide, polydextrose, and mixtures of these. There is evidence that addition of prebiotics in infant formula alters the gastrointestinal (GI) microbiota resembling that of breastfed infants. They are added to infant formula because of their presence in breast milk. Infants on these supplemented formula have a lower stool pH, a better stool consistency and frequency and a higher concentration of bifidobacteria in their intestine compared to infants on a non-supplemented standard formula. Since most studies suggest a trend for beneficial clinical effects, and since these ingredients are very safe, prebiotics bring infant formula one step closer to breastmilk, the golden standard. However, despite the fact that adverse events are rare, the evidence on prebiotics of a significant health benefit throughout the alteration of the gut microbiota is limited.

  6. The effect of paramedic training on pre-hospital trauma care (EPPTC-study): a study protocol for a prospective semi-qualitative observational trial

    Science.gov (United States)

    2014-01-01

    Background Accidents are the leading cause of death in adults prior to middle age. The care of severely injured patients is an interdisciplinary challenge. Limited evidence is available concerning pre-hospital trauma care training programs and the advantage of such programs for trauma patients. The effect on trauma care procedures or on the safety of emergency crews on the scene is limited; however, there is a high level of experience and expert opinion. Methods I – Video-recorded case studies are the basis of an assessment tool and checklist being developed to verify the results of programs to train participants in the care of seriously injured patients, also known as “objective structured clinical examination” (OSCE). The timing, completeness and quality of the individual measures are assessed using appropriate scales. The evaluation of team communication and interaction will be analyzed with qualitative methods and quantified and verified by existing instruments (e.g. the Clinical Team Scale). The developed assessment tool is validated by several experts in the fields of trauma care, trauma research and medical education. II a) In a German emergency medical service, the subjective assessment of paramedics of their pre-hospital care of trauma patients is evaluated at three time points, namely before, immediately after and one year after training. b) The effect of a standardized course concept on the quality of documentation in actual field operations is determined based on three items relevant to patient safety before and after the course. c) The assessment tool will be used to assess the effect of a standardized course concept on procedures and team communication in pre-hospital trauma care using scenario-based case studies. Discussion This study explores the effect of training on paramedics. After successful study completion, further multicenter studies are conceivable, which would evaluate emergency-physician staffed teams. The influence on the patients

    Full Text Available The biggest hurdle for early hospital presentation is the narrow therapeutic window after stroke. The aims of our study were to investigate the time lags and the factors causing pre-hospital and emergency department (ED delay during acute ischemic stroke attack. Between June 2004 and October 2005, we prospectively studied 129 acute ischemic stroke patients who presented to the ED of the study hospital within 4 hours after symptom onset. Chi-square testing for trend, uni-variate and multiple logistic regression analyses was performed to evaluate the factors influencing delays in the ED presentation of acute ischemic stroke patients. The median time from symptom onset to ED arrival was 71 (mean ± SD, 82.7 ± 57.7 minutes. The median times from ED arrival to neurologic consultation, computed tomography scan, electrocardiogram, and laboratory data completion were 10 (11.3±9.9 minutes, 17 (9.6±11.3 minutes, 14 (23.3±55 minutes, and 39 (44.4±24.5 minutes, respectively. Univariate and multiple logistic regression models revealed that age < 65 years, illiteracy and awakening with symptoms were the most significant factors related to a delay in ED presentation. This study indicates that 2 hours of pre-hospital delay is the cutoff point for thrombolytic therapy. Organization of a stroke team and standardized stroke pathways may help to shorten in-hospital time consumption. Educational efforts should not only focus on the public, but also on the training of ED physicians and other medical personnel.

    Chest pain and acute dyspnoea are frequent causes of emergency medical services activation. The pre-hospital management of these conditions is heterogeneous across different regions of the world and Europe, as a consequence of the variety of emergency medical services and absence of specific practical guidelines. This position paper focuses on the practical aspects of the pre-hospital treatment on board and transfer of patients taken in charge by emergency medical services for chest pain and dyspnoea of suspected cardiac aetiology after the initial assessment and diagnostic work-up. The objective of the paper is to provide guidance, based on evidence, where available, or on experts' opinions, for all emergency medical services' health providers involved in the pre-hospital management of acute cardiovascular care. © The European Society of Cardiology 2015.

This strategy may lead to an undesirable increase in osmolality of feeds, the maximum recommended safe limit being 400 mOsm/kg. The aim of the study was to measure the changes in osmolality of several commercialized preterm formulas after addition of glucose polymers and medium-chain triglycerides. Osmolality was measured by the freezing point depression method. Six powdered formulas with concentrations of 14 g/100 ml and 16 g/100 ml, and five ready-to-feed liquid formulas were analyzed. All formulas, were supplemented with 10% (low supplementation) or 20% (high supplementation) of additional calories, respectively, in the form of glucose polymers and medium chain triglycerides, maintaining a 1:1 glucose:lipid calorie ratio. Inter-analysis and intra-analysis coefficients of variation of the measurements were always supplemented formulas varied between 268.5 and 315.3 mOsm/kg, increasing by 3-5% in low supplemented formulas, and by 6-10% in high supplemented formulas. None of the formulas analyzed exceeded 352.8 mOsm/kg. The supplementation of preterm formulas with nonprotein energy supplements with up to 20% additional calories did not exceed the maximum recommended osmolality for neonatal feedings.

    This article presents a fast new numerical method for redistancing objective functions based on the Hopf-Lax formula [1]. The algorithm suggested here is a special case of the previous work in [2] and an extension that applies the Hopf-Lax formula for computing the signed distance to the front. We propose the split Bregman approach to solve the minimization problem as a solution of the eikonal equation obtained from Hopf-Lax formula. Our redistancing procedure is expected to be generalized and widely applied to many fields such as computational fluid dynamics, the minimal surface problem, and elsewhere.

    This paper reports the measurement of [Formula: see text] meson production in proton-proton ([Formula: see text]) and proton-lead ([Formula: see text]) collisions at a center-of-mass energy per nucleon pair of [Formula: see text] by the CMS experiment at the LHC. The data samples used in the analysis correspond to integrated luminosities of 28[Formula: see text] and 35[Formula: see text] for [Formula: see text] and [Formula: see text] collisions, respectively. Prompt and nonprompt [Formula: see text] mesons, the latter produced in the decay of [Formula: see text] hadrons, are measured in their dimuon decay channels. Differential cross sections are measured in the transverse momentum range of [Formula: see text], and center-of-mass rapidity ranges of [Formula: see text] ([Formula: see text]) and [Formula: see text] ([Formula: see text]). The nuclear modification factor, [Formula: see text], is measured as a function of both [Formula: see text] and [Formula: see text]. Small modifications to the [Formula: see text] cross sections are observed in [Formula: see text] relative to [Formula: see text] collisions. The ratio of [Formula: see text] production cross sections in [Formula: see text]-going and Pb-going directions, [Formula: see text], studied as functions of [Formula: see text] and [Formula: see text], shows a significant decrease for increasing transverse energy deposited at large pseudorapidities. These results, which cover a wide kinematic range, provide new insight on the role of cold nuclear matter effects on prompt and nonprompt [Formula: see text] production.

    Full Text Available Introduction: Endotracheal intubation (ETI is currently considered superior to supraglottic airway devices (SGA for survival and other outcomes among adults with non-traumatic out-of-hospital cardiac arrest (OHCA. We aimed to determine if the research supports this conclusion by conducting a systematic review. Methods: We searched the MEDLINE, Scopus and CINAHL databases for studies published between January 1, 1980, and 30 April 30, 2013, which compared pre-hospital use of ETI with SGA for outcomes of return of spontaneous circulation (ROSC; survival to hospital admission; survival to hospital discharge; and favorable neurological or functional status. We selected studies using pre-specified criteria. Included studies were independently screened for quality using the Newcastle-Ottawa scale. We did not pool results because of study variability. Study outcomes were extracted and results presented as summed odds ratios with 95% CI. Results: We identified five eligible studies: one quasi-randomized controlled trial and four cohort studies, involving 303,348 patients in total. Only three of the five studies reported a higher proportion of ROSC with ETI versus SGA with no difference reported in the remaining two. None found significant differences between ETI and SGA for survival to hospital admission or discharge. One study reported better functional status at discharge for ETI versus SGA. Two studies reported no significant difference for favorable neurological status between ETI and SGA. Conclusion: Current evidence does not conclusively support the superiority of ETI over SGA for multiple outcomes among adults with OHCA. [West J Emerg Med. 2014;15(7:-0.

    The King LT(S)-D laryngeal tube (King LT) has gained popularity as a bridge airway for pre-hospital airway management. In this study, we retrospectively reviewed the use of the King LT and its associated airway outcomes at a single Level 1 trauma centre. The data on all adult patients presenting to the Mayo Clinic in Rochester, Minnesota with a King LT in situ from July 1, 2007 to October 10, 2012 were retrospectively evaluated. Data collected and descriptively analyzed included patient demographics, comorbidities, etiology of respiratory failure, airway complications, subsequent definitive airway management technique, duration of mechanical ventilation, and status at discharge. Forty-eight adult patients met inclusion criteria. The most common etiology for respiratory failure requiring an artificial airway was cardiac arrest [28 (58%) patients] or trauma [9 (19%) patients]. Four of the nine trauma patients had facial trauma. Surgical tracheostomy was the definitive airway management technique in 14 (29%) patients. An airway exchange catheter, direct laryngoscopy, and video laryngoscopy were used in 11 (23%), ten (21%), and ten (21%) cases, respectively. Seven (78%) of the trauma patients underwent surgical tracheostomy compared with seven (18%) of the medical patients. Adverse events associated with King LT use occurred in 13 (27%) patients, with upper airway edema (i.e., tongue engorgement and glottic edema) being most common (19%). In this study of patients presenting to a hospital with a King LT, the majority of airway exchanges required an advanced airway management technique beyond direct laryngoscopy. Upper airway edema was the most common adverse observation associated with King LT use.

    Scarce evidence yields conflicting results regarding the effect of prodromal chest pain (PCP) on pre-hospital delay during an acute myocardial infarction (AMI). We aimed to assess the impact of PCP on delay. Data was collected on 619 ST-elevated MI patients from the multicenter Munich Examination of Delay in Patients Experiencing Acute Myocardial Infarction (MEDEA) study. Patients with any PCP (which was subdivided into undefined PCP, possible and definite angina) within a year before AMI were identified using the Rose questionnaire, administered in bedside interviews. The influence of PCP and its subdivisions (all compared to no PCP) was assessed using logistic regression (with cut-offs of 2 h, 6 h, and a 4-category ordinal outcome). Any type of PCP was reported by men (50.6%) more than women (34.6%) (OR=1.9; 95% CI: 1.3 to 2.8; p=.001). The median delay of patients with PCP was not significantly different to delay in patients with no PCP (p=.327). Prolonged delay times were observed in women with PCPs of lesser degree of cardiac confirmation, while the opposite was observed in men. In women, possible angina was more strongly associated with delay <2 h (OR=6.8; 95% CI=2 to 23.8) than any PCP (OR=2.6; 95% CI=1.2 to 5.7). For men, PCPs of increasing cardiac confirmation are associated with prolonged delay. For women, PCPs of lesser cardiac confirmation are more likely to lead to prolonged delay. Future studies should investigate mediating factors. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    2014-01-01

    Full Text Available The paper systematically describes an approach to solution of initial and initial-boundary value problems for evolution equations based on the representation of the corresponding evolution semigroups with the help of Feynman formulae. The article discusses some of the methods of constructing Feynman formulae for different evolution semigroups, presents specific examples of solutions of evolution equations. In particular, Feynman formula is obtained for evolution semigroups generated by multiplicative perturbations of generators of some initial semigroups. In this case semigroups on a Banach space of continuous functions defined on an arbitrary metric space are considered; Feynman formulae are constructed with the help of operator families, which are Chernoff equivalent to the initial unperturbed semigroups. The present result generalizes the author's paper \\Feynman formula for semigroups with multiplicative perturbed generators" and some of the results of the joint with O.G. Smolyanov and R.L. Schilling paper \\Lagrangian and Hamiltonian Feynman formulae for some Feller processes and their perturbations". The approach to the construction of Feynman formulae for semigroups with multiplicative and additive perturbed generators is illustrated with examples of the Cauchy problem for the Schrodinger equation, the approximation of transition probabilities of some Markov processes.Further, a wider class of additive and multiplicative perturbations of a particular generator | the Laplace operator | is considered in the paper. And Feynman formula for the solution of the Cauchy problem for a second order parabolic equation with unbounded variable coefficients is proved. In addition, the article describes a method for constructing Feynman formulae for solutions of the Cauchy | Dirichlet problem for parabolic differential equations. The method is also illustrated by a second order parabolic equation with variable coefficients. These results generalize some

    Full Text Available Background Circulatory management is a critical issue in pre-hospital transportation phase of multiple trauma patients. However, the quality of this important care did not receive enough attention. Objectives The aim of this study was to investigate the quality of pre-hospital circulatory management in patients with multiple trauma. Patients and Methods This was a cross-sectional study conducted in 2013. The study population consisted of all patients with multiple trauma who had been transferred by emergency medical services (EMS to the central trauma department in Kashan Shahid Beheshti medical center, Kashan, Iran. We recruited a convenience sample of 400 patients with multiple trauma. Data were collected using the circulatory assessment questionnaire and controlling hemorrhage (CAQCH that were designed by the researchers and were described by using frequency tabulations, central tendency measures, and variability indices. The chi-square test was used to analyze the data. Results The study sample consisted of 263 males (75.2%; 57.75% had lower levels of education and 28.75% were workers. The most common mechanism of trauma was traffic accident (85.4%. We found that the quality of circulatory management was unfavorable in 61% of the cases. A significant relationship was observed between the quality of circulatory management and type of trauma and staff’s employment status. Conclusions The quality of pre-hospital circulatory management provided to patients with multiple trauma was unfavorable. Therefore, establishment of in-service training programs on circulatory management is recommended.

    2010-01-01

    We study possible formulations of algebraic propositional proof systems operating with noncommutative formulas. We observe that a simple formulation gives rise to systems at least as strong as Frege---yielding a semantic way to define a Cook-Reckhow (i.e., polynomially verifiable) algebraic analogue of Frege proofs, different from that given in [BIKPRS96,GH03]. We then turn to an apparently weaker system, namely, polynomial calculus (PC) where polynomials are written as ordered formulas ("PC over ordered formulas", for short). This is an algebraic propositional proof system that operates with noncommutative polynomials in which the order of products in all monomials respects a fixed linear order on the variables, and where proof-lines are written as noncommutative formulas. We show that the latter proof system is strictly stronger than resolution, polynomial calculus and polynomial calculus with resolution (PCR) and admits polynomial-size refutations for the pigeonhole principle and the Tseitin's formulas.

    Krajewska, K; Kamiński, J Z

    2015-01-01

    The generalized Klein-Nishina formula for Compton scattering of charged particles by a finite train of pulses is derived in the framework of quantum electrodynamics. The formula also applies to classical Thomson scattering provided that frequencies of generated radiation are smaller that the cut-off frequency. The validity of the formula for incident pulses of different durations is illustrated by numerical examples. The positions of the well-resolved Compton peaks, with the clear labeling by integer orders, opens up the possibility of the precise diagnostics of properties of relativistically intense, short laser pulses. This includes their peak intensity, the carrier-envelope phase, and their polarization properties.

    Du, Yi-jian; Wu, Yong-shi

    2016-01-01

    In this paper, we study the relation between the Cachazo-He-Yuan (CHY) formula and the maximal-helicity-violating (MHV) amplitudes of Yang-Mills and gravity in four dimensions. We prove that only one special rational solution of the scattering equations found by Weinzierl support the MHV amplitudes. Namely, localized at this solution, the integrated CHY formula reproduces the Parke-Taylor formula for Yang-Mills amplitudes as well as the Hodges formula for gravitational amplitudes. This is achieved by developing techniques, in a manifestly M\\"obius covariant formalism, to explicitly compute relevant reduced Pfaffians/determinants. We observe and prove two interesting properties (or identities), which facilitate the computations. We also check that all the other $(n-3)!-1$ solutions to the scattering equations do not support the MHV amplitudes, and prove analytically that this is indeed true for the other special rational solution proposed by Weinzierl, that actually supports the anti-MHV amplitudes.

    2008-04-01

    We show that semiclassical formulas such as the Gutzwiller trace formula can be implemented on a quantum computer more efficiently than on a classical device. We give explicit quantum algorithms which yield quantum observables from classical trajectories, and which alternatively test the semiclassical approximation by computing classical actions from quantum evolution. The gain over classical computation is in general quadratic, and can be larger in some specific cases.

    Acute heart failure is a fatal syndrome. Emergency physicians, cardiologists, intensivists, nurses and other health care providers have to cooperate to provide optimal benefit. However, many treatment decisions are opinion-based and few are evidenced-based. This consensus paper provides guidance to practicing physicians and nurses to manage acute heart failure in the pre-hospital and hospital setting. Criteria of hospitalization and of discharge are described. Gaps in knowledge and perspectives in the management of acute heart failure are also detailed. This consensus paper on acute heart failure might help enable contiguous practice.

  13. Convenient formulae for some integrals in perturbation theory

    Directory of Open Access Journals (Sweden)

    D. Henderson

    2010-01-01

    Full Text Available The free energy and pressure of a fluid, as given by perturbation theory, involve integrals of the hard sphere correlation functions and their density derivatives. In most applications a straightforward procedure would be to obtain these integrals, possibly numerically, using the formulae and computer codes for the hard sphere correlation functions, given previously [Mol. Phys., 2007, 106, 2; Condens. Matter Phys., 2009, 12, 127], followed by numerical differentiation with respect to the density and a possible compounding of errors. More sophisticated methods are given in this paper, which is the second in a planned trilogy, drawn from the author's lecture notes. Three representative model fluids are considered. They are the square-well fluid, the Yukawa fluid, and the Lennard-Jones fluid. Each model fluid is popular for theoretical and engineering calculations and can represent a simple fluid such as argon. With the methods presented here, numerical integration and differentiation are not necessary for the square-well and Yukawa fluids. Numerical integration cannot be easily avoided in the case of the Lennard-Jones fluid. However, numerical differentiation with respect to the density is not required.

    Full Text Available In this work we want to show that the mathematical model of quantum mechanics, led to its classical approach, is able to reproduce as close macroscopic experimental results captured by the Manning formula, sufficiently verified through their diverse applications in hydraulics. Molecular interaction between the fluid and the wall of the vessel is studied decomposing the Hamiltonian in two parts: free, and interacting. Scaling process is considered from molecular to hydraulic. Participation of the symmetries of Saint-Venant equation in the hydraulic gradient is taken into account. Correlations between different variables are set. The magnitude of scale change is estimated. We conclude that the Compton wavelength induces to the Boussinesq viscosity concept and the characteristic length of the viscous sublayer.

    2004-12-01

    Foods, which, in addition to their nutritional attributes, contain also elements that are considered to be health-promoting, have been termed "functional foods". In this regard, human milk has gained recognition as being the ultimate functional food for infants - by its biological compatibility, nutritional value and the undisputed added value of its health promoting qualities. Intensive research activity has recently evolved in a quest to identify and define the components of human milk that might confer disease-preventing and health-enhancing properties and to determine the instances and clinical conditions in which these factors become particularly important. The outcome of such research would also provide a rationale for advocating the supplementation of commercial infant formulas with such substances. In effect, the body of data accumulated from scientific and clinical studies on nucleotides, probiotics, prebiotics and long-chain polyunsaturated fatty acids in human milk and as additives to infant formula, has become regarded as convincing enough by the infant formula industry so as to launch into the market formulas supplemented with one or more of these factors - in an effort to emulate human milk and its beneficial effects. The following review is intended for the reader to obtain a general idea of the new supplements that have been introduced to infant formulas. We summarize the pertinent experimental and clinical observations concerning each of the supplements, pointing out their potential specific benefits, their possible disadvantages and the issues that still remain unresolved.

    1999-03-01

    Refrigerating fluids are experiencing a real revolution since few years. CFCs with their destructive effect on the ozone layer are now prohibited while HCFCs will be progressively eliminated and replaced by HFCs. However, HFCs can contribute to the increase of the greenhouse effect. The solutions proposed by thermal engineering professionals consist in the confinement of air-conditioning installations (elimination of recurrent leaks) and in the improvement of installations efficiency. HCFC fluids like the R 22 are still widely used in air-conditioning but they are supposed to be replaced by HFC fluids like the R 134a, the R 407C or the R 410A. This short paper gives a brief presentation of these fluids and of their chemical characteristics. (J.S.)

  1. The Formula of Plague Narratives

    2015-01-01

    The article is a narratological investigation of a selection of plague tales. The selection spans millennia and different text types, technologies and genres, from The Bible to apocalyptical films, iPhone games and testimonials from Médecins Sans Frontières. The research question is whether...... it is possible to establish a stable formula for plague narratives despite the spread over centuries and in different text types, and to explain this formula and possible variations of it. The initial and tentative hypothesis is that a formulaic narrative structure exists for accounts, both documentary...... and fictional, of epidemics. The samples include: Exodus, History of the Peloponnesian War, Samuel Pepys’ Diary, A Journal of the Plague Year, The Last Man, The Plague in Bergamo, Discipline and Punish: The Birth of the Prison, Doomsday, The Dead Zone, World War Z.

    In this paper, we give formulas for the swimming of simplified two-dimensional bodies in complex fluids using the reciprocal theorem. By way of these formulas we calculate the swimming velocity due to small-amplitude deformations on the simplest of these bodies, a two-dimensional sheet, to explore general conditions on the swimming gait under which the sheet may move faster, or slower, in a viscoelastic fluid compared to a Newtonian fluid.

  3. Reasoning on Schemata of Formulae

    Echenim, Mnacho

    2012-01-01

    A logic is presented for reasoning on iterated sequences of formulae over some given base language. The considered sequences, or "schemata", are defined inductively, on some algebraic structure (for instance the natural numbers, the lists, the trees etc.). A proof procedure is proposed to relate the satisfiability problem for schemata to that of finite disjunctions of base formulae. It is shown that this procedure is sound, complete and terminating, hence the basic computational properties of the base language can be carried over to schemata.

  4. CHY formulae in 4d

    CERN Document Server

    Zhang, Yong

    2016-01-01

    In this paper, we develop a rather general way to reduce integrands with polarisation involved in the Cachazo-He-Yuan formulae, such as the reduced Pfaffian and its compactification, as well as the new object for F3 amplitude. We prove that the reduced Pfaffian vanishes unless on a certain set of solutions. It leads us to build up the 4d CHY formulae using spinors, which strains off many useless solutions. The supersymmetrization is straightforward and may provide a hint to understanding ambitwistor string in 4d.

  5. Geometric formula for prism deflection

    Indian Academy of Sciences (India)

    Apoorva G Wagh; Veer Chand Rakhecha

    2004-08-01

    While studying neutron deflections produced by a magnetic prism, we have stumbled upon a simple `geometric' formula. For a prism of refractive index close to unity, the deflection simply equals the product of the refractive power − 1 and the base-to-height ratio of the prism, regardless of the apex angle. The base and height of the prism are measured respectively along and perpendicular to the direction of beam propagation within the prism. The geometric formula greatly simplifies the optimisation of prism parameters to suit any specific experiment.

  6. Cubature formulas on combinatorial graphs

    CERN Document Server

    Pesenson, Isaac Z

    2011-01-01

    Many contemporary applications, for example, cataloging of galaxies, document analysis, face recognition, learning theory, image processing, operate with a large amount of data which is often represented as a graph embedded into a high dimensional Euclidean space. The variety of problems arising in contemporary data processing requires development on graphs such topics of the classical harmonic analysis as Shannon sampling, splines, wavelets, cubature formulas. The goal of the paper is to establish cubature formulas on finite combinatorial graphs. The results have direct applications to problems that arise in connection with data filtering, data denoising and data dimension reduction.

    Full Text Available Mothers’ own milk is the best source of nutrition for nearly all infants. Beyond somatic growth, breast milk as a biologic fluid has a variety of other benefits, including modulation of postnatal intestinal function, immune ontogeny, and brain development. Although breastfeeding is highly recommended, breastfeeding may not always be possible, suitable or solely adequate. Infant formula is an industrially produced substitute for infant consumption. Infant formula attempts to mimic the nutritional composition of breast milk as closely as possible, and is based on cow’s milk or soymilk. A number of alternatives to cow’s milk-based formula also exist. In this article, we review the nutritional information of breast milk and infant formulas for better understanding of the importance of breastfeeding and the uses of infant formula from birth to 12 months of age when a substitute form of nutrition is required.

  1. Comparison of Tissue Preservation using Formalin and Ethanol as Preservative Formula

    Directory of Open Access Journals (Sweden)

    See Woan Shian

    2016-09-01

    Full Text Available Background: Tissue preservation can be performed through embalming, by providing the chemical embalming fluid to the human remains. Formalin’s preservative formula is the foundation for modern methods of embalming. Unfortunately, this preservative formula has several disadvantages. While Ethanol’s preservative formula is a considerable agent to replace formalin’s preservative formula. The aim of this study was to compare the tissue preservation using formalin and ethanol as preservative formula. Methods: This study was carried out from September–October 2014 in the Laboratory of the Department of Anatomy, Faculty of Medicine, Universitas Padjadjaran. The study used the laboratory experimental method with consecutive sampling of 16 Wistar Rats. Thirty two soleus muscles and thirty two colons were collected and divided into two groups. Each group consisted of 16 soleus muscles and 16 colons. Group 1 was preserved with formalin’s preservative formula and Group 2 was preserved with ethanol’s preservative formula. The two groups were preserved for six weeks. The tissue’s color, consistency, odor and the growth of bacteria were determined before and after treatment. Results: Tissues preserved with ethanol’s preservative formula had better tissue preservation in the aspect of color and odor, compared with formalin’s preservative formula. Both preservative formulas showed no growth of bacteria in tissues but failed to retain the consistency. All the data were analyzed with Chi-square test. Conclusions: Ethanol’s preservative formula preserves better quality of tissue compared to formalin’s preservative formula.

  2. Koide's Mass Formula for Neutrinos

    Brannen, Carl

    2006-05-01

    We derive Koide's mass formula as an eigenvector equation. We show that to within current experimental error, the square roots of the masses of the charged leptons follow the simple equation (m^-n)^0.5 = μ1(1 + √2(δ1+ 2nπ/3)) where δ1 is the interesting number .22222204717(48) and μ1 is a constant. Next we generalize the Koide formula to the neutrinos by assuming that the square root of the mass of the smallest neutrino must be taken to be negative. Then masses of the simple form (m^0n)^0.5 = μ0(1 + √2(δ1+ π/12 + 2nπ/3)) where 3;μ0= 3^12 ;μ1, satisfy recent neutrino oscillation measurements close to the centers of the error bars. Finally, we discuss the preon model for the fermions that led to the above discovery.

  3. The Callias index formula revisited

    CERN Document Server

    Gesztesy, Fritz

    2016-01-01

    These lecture notes aim at providing a purely analytical and accessible proof of the Callias index formula. In various branches of mathematics (particularly, linear and nonlinear partial differential operators, singular integral operators, etc.) and theoretical physics (e.g., nonrelativistic and relativistic quantum mechanics, condensed matter physics, and quantum field theory), there is much interest in computing Fredholm indices of certain linear partial differential operators. In the late 1970’s, Constantine Callias found a formula for the Fredholm index of a particular first-order differential operator (intimately connected to a supersymmetric Dirac-type operator) additively perturbed by a potential, shedding additional light on the Fedosov-Hörmander Index Theorem. As a byproduct of our proof we also offer a glimpse at special non-Fredholm situations employing a generalized Witten index.

    Black hole formula 1) Second dimension (x,y) f(x)=y Energy E=m*c2 2) Third dimension (x,y,z) really x=y=z Black hole formula Root(c2)=c=Root(E/m) As mass go the velocity of light, mass become black hole so there are energy as multiply by mass. Example relativity When E=m*c2 1) Root(c2)=c=Root(E/m) 2) 3*c*Root(c2)=3*c*Root(E/m)=3*c2 From 1) to 2) as an example, As velocity is faster, mass increased. It means when velocity is increased, sec(time) is slower, and m(distance) is increased. The number is good to study physics.

    We construct Koppelman formulas on manifolds of flags in $\\C^N$ for forms with values in any holomorphic line bundle as well as in the tautological vector bundles and their duals. As an application we obtain new explicit proofs of some vanishing theorems of the Bott-Borel-Weil type by solving the corresponding $\\debar$-equation. We also construct reproducing kernels for harmonic $(p,q)$-forms in the case of Grassmannians.

    Let F be a uniformly distributed random k-SAT formula with n variables and m clauses. We prove that the Walksat algorithm from Papadimitriou (FOCS 1991)/Schoning (FOCS 1999) finds a satisfying assignment of F in polynomial time w.h.p. if m/n0. This is an improvement by a factor of $\\Theta(k)$ over the best previous analysis of Walksat from Coja-Oghlan, Feige, Frieze, Krivelevich, Vilenchik (SODA 2009).

    2011-01-01

    We give an explicit solution of the ADHM recursion formula conjectured by Chuang, Diaconescu, and Pan. This solution is closely related to the formula for the Hodge polynomials of Higgs moduli spaces conjectured by Hausel and Rodriguez-Villegas. We solve also the twisted motivic ADHM recursion formula. As a byproduct we obtain a conjectural formula for the motives of twisted Higgs moduli spaces, which generalizes the conjecture of Hausel and Rodriguez-Villegas.

  16. Transport Coefficients of Fluids

    CERN Document Server

    Eu, Byung Chan

    2006-01-01

    Until recently the formal statistical mechanical approach offered no practicable method for computing the transport coefficients of liquids, and so most practitioners had to resort to empirical fitting formulas. This has now changed, as demonstrated in this innovative monograph. The author presents and applies new methods based on statistical mechanics for calculating the transport coefficients of simple and complex liquids over wide ranges of density and temperature. These molecular theories enable the transport coefficients to be calculated in terms of equilibrium thermodynamic properties, and the results are shown to account satisfactorily for experimental observations, including even the non-Newtonian behavior of fluids far from equilibrium.

    As we know, a solution of an extremal problem with Hermite interpolation constraints is a system of nodes of corresponding Gaussian Hermite quadrature formula (the so-called Jacobi approach). But this conclusion is violated for a Birkhoff quadrature formula. In this paper an extremal problem with Birkhoff interpolation constraints is discussed, from which a large class of Birkhoff quadrature formulas may be derived.

    The nuclear modification factor [Formula: see text] and the azimuthal anisotropy coefficient [Formula: see text] of prompt and nonprompt (i.e. those from decays of b hadrons) [Formula: see text] mesons, measured from PbPb and pp collisions at [Formula: see text] [Formula: see text] at the LHC, are reported. The results are presented in several event centrality intervals and several kinematic regions, for transverse momenta [Formula: see text] [Formula: see text] and rapidity [Formula: see text], extending down to [Formula: see text] [Formula: see text] in the [Formula: see text] range. The [Formula: see text] of prompt [Formula: see text] is found to be nonzero, but with no strong dependence on centrality, rapidity, or [Formula: see text] over the full kinematic range studied. The measured [Formula: see text] of nonprompt [Formula: see text] is consistent with zero. The [Formula: see text] of prompt [Formula: see text] exhibits a suppression that increases from peripheral to central collisions but does not vary strongly as a function of either y or [Formula: see text] in the fiducial range. The nonprompt [Formula: see text] [Formula: see text] shows a suppression which becomes stronger as rapidity or [Formula: see text] increases.

  4. Modern trends in fluid therapy for burns.

    Science.gov (United States)

    Tricklebank, Stephen

    2009-09-01

    The majority of burn centres use the crystalloid-based Parkland formula to guide fluid therapy, but patients actually receive far more fluid than the formula predicts. Resuscitation with large volumes of crystalloid has numerous adverse consequences, including worsening of burn oedema, conversion of superficial into deep burns, and compartment syndromes. Resuscitation fluids influence the inflammatory response to burns in different ways and it may be possible, therefore to affect this response using the appropriate fluid, at the appropriate time. Starches are effective volume expanders and early use of newer formulations may limit resuscitation requirements and burn oedema by reducing inflammation and capillary leak. Advanced endpoint monitoring may guide clinicians in when to 'turn off' aggressive fluid therapy and therefore avoid the problems of over-resuscitation.

  5. Non-Newtonian Properties of Relativistic Fluids

    CERN Document Server

    Koide, Tomoi

    2010-01-01

    We show that relativistic fluids behave as non-Newtonian fluids. First, we discuss the problem of acausal propagation in the diffusion equation and introduce the modified Maxwell-Cattaneo-Vernotte (MCV) equation. By using the modified MCV equation, we obtain the causal dissipative relativistic (CDR) fluid dynamics, where unphysical propagation with infinite velocity does not exist. We further show that the problems of the violation of causality and instability are intimately related, and the relativistic Navier-Stokes equation is inadequate as the theory of relativistic fluids. Finally, the new microscopic formula to calculate the transport coefficients of the CDR fluid dynamics is discussed. The result of the microscopic formula is consistent with that of the Boltzmann equation, i.e., Grad's moment method.

    2007-01-01

    @@ Many attempts have been made to standardize the calculation of whiteness. Whiteness formulas currently in use satisfactorily characterize the appearance of commercial whiteness. However, they have poor correlations with the observers' evaluations, and are often unsuccessful in assessing tinted white samples.A whiteness formula in the CIELAB uniform color space is developed in this paper. Several whiteness formulas are analyzed and compared. The experimental results show that the whiteness formula in the CIELAB uniform color space agrees well with the visual ranking, and it is superior to the CIE whiteness formula and the others in visual correlativity, uniformity and applicability.

    The difference between the electromagnetic self-energies of proton and neutron can be calculated with the Cottingham formula, which expresses the self-energies as an integral over the electroproduction cross sections - provided the nucleon matrix elements of the current commutator do not contain a fixed pole. We show that, under the same proviso, the subtraction function occurring in the dispersive representation of the virtual Compton forward scattering amplitude is determined by the cross sections. The representation in particular leads to a parameter-free sum rule for the nucleon polarisabilities. We evaluate the sum rule for the difference between the electric polarisabilities of proton and neutron by means of the available parameterisations of the data and compare the result with experiment.

    YANG, S.

    2014-11-01

    Full Text Available This paper presents how to search mathematical formulae written in MathML when given plain words as a query. Since the proposed method allows natural language queries like the traditional Information Retrieval for the mathematical formula search, users do not need to enter any complicated math symbols and to use any formula input tool. For this, formula data is converted into plain texts, and features are extracted from the converted texts. In our experiments, we achieve an outstanding performance, a MRR of 0.659. In addition, we introduce how to utilize formula classification for formula search. By using class information, we finally achieve an improved performance, a MRR of 0.690.

    Hickey, T

    1993-02-01

    With the increase in interest in formulas, or apparently non-productive utterances in children's speech, a range of definitions has emerged and sometimes conflicting criteria have been proposed for their identification. These definitions of formulas are compared, and the criteria of Brown (1973), Wong Fillmore (1976), Peters (1983) and Plunkett (1990) for the recognition of formulas are reviewed. A preference rule system is proposed, which distinguishes necessary, typical and graded conditions for the recognition of formulas. Using these conditions, some of the formulas found in the data of one child acquiring Irish between 1;4 and 2;1 are examined. Issues such as length of units, frequency of occurrence and appropriateness of use are discussed. The methods developed in this study could be used to assess the importance of formulas in the language acquisition of other children.

    Guldager, Jan G.; Schröder, Philipp J.H.

    . This paper presents a two country intra-industry trade model with heterogeneous firms subject to high and low tariffs. We examine the welfare effects of applying three different tariff reduction formulas proposed in the literature i) a proportional cut, ii) the Swiss formula and iii) a compression formula......WTO negotiations rely on tariff reduction formulas. It has been argued that formula approaches are of increasing importance in trade talks, because of the large number of countries involved, the wider dispersion in initial tariffs (e.g. tariff peaks) and gaps between bound and applied tariff rates....... No single formula dominates for all conditions. The ranking of the three tools depends on the degree of product differentiation in the industry, and the achieved reduction in the average tariff....

    Zoppi, G

    1993-01-01

    According to the definition of the European Scientific Committee for Food, hypoallergenic or hypoantigenic formulas (HA-formulas) are those which contain hydrolysed protein derived both from casein or whey. Soy-based formulas are not comprised in this definition since it has been demonstrated from several years that soy-protein, in several circumstances, may be highly allergenic. Hypoallergenic formulas contain besides hydrolysed protein, carbohydrate and lipid in amount and proportion similar to those indicated by ESPGAN recommendations on adapted formulas. As far as it concerns composition in lipid, recently great attention has been given to optimal supply and ratio of omega 3 and omega 6 fatty acids. Hypoallergenic formulas are therefore suitable for balanced nutrition of suckling infants. Specific indications on prevention of atopic diseases are not treated.

    Generating knowledge through quality research is fundamental to the advancement of professional practice in emergency nursing and care. There are multiple paradigms, designs and methods available to researchers to respond to challenges in clinical practice. Systematic reviews, randomised control trials and other forms of experimental research are deemed the gold standard of evidence, but there are comparatively few such trials in emergency care. In some instances it is not possible or appropriate to undertake experimental research. When exploring new or emerging problems where there is limited evidence available, non-experimental methods are required and appropriate. This paper provides the theoretical foundations and an exemplar of the use of case study and case-based research to explore a new and emerging problem in the context of emergency care. It examines pre-hospital clinical judgement and decision-making of mental illness by paramedics. Using an exemplar the paper explores the theoretical foundations and conceptual frameworks of case study, it explains how cases are defined and the role researcher in this form of inquiry, it details important principles and the procedures for data gathering and analysis, and it demonstrates techniques to enhance trustworthiness and credibility of the research. Moreover, it provides theoretically and practical insights into using case study in emergency care. Copyright © 2017 College of Emergency Nursing Australasia. Published by Elsevier Ltd.

    2013-01-01

    Elements and Formulae of Special Relativity presents elements and formulas of the theory of special relativity and covers topics ranging from kinematics and propagation of light to mechanics of single bodies, hydrodynamics, and thermodynamics. Vector operators, electromagnetic fields, electrodynamics, and statistical mechanics are also explored. This book is comprised of 13 chapters and begins by introducing the reader to the kinematics of special relativity, paying particular attention to formulas required for transformations between two frames of reference. Attention then turns to the propag

  5. Synthesizing Accurate Floating-Point Formulas

    2013-01-01

    International audience; Many critical embedded systems perform floating-point computations yet their accuracy is difficult to assert and strongly depends on how formulas are written in programs. In this article, we focus on the synthesis of accurate formulas mathematically equal to the original formulas occurring in source codes. In general, an expression may be rewritten in many ways. To avoid any combinatorial explosion, we use an intermediate representation, called APEG, enabling us to rep...

  6. Whitney's formulas for curves on surfaces

    CERN Document Server

    Burman, Yurii

    2009-01-01

    The classical Whitney formula relates the number of times an oriented plane curve cuts itself to its rotation number and the index of a base point. In this paper we generalize Whitney's formula to curves on an oriented punctured surface. To define analogs of the rotation number and the index of a base point of a curve, we fix an arbitrary vector field on the surface. Similar formulas are obtained for non-based curves.

    2011-01-01

    The literature on reconstruction formulas for photoacoustic tomography (PAT) is vast. The various reconstruction formulas differ by used measurement devices and geometry on which the data are sampled. In standard photoacoustic imaging (PAI), the object under investigation is illuminated uniformly. Recently, sectional photoacoustic imaging techniques, using focusing techniques for initializing and measuring the pressure along a plane, appeared in the literature. This paper surveys existing and provides novel exact reconstruction formulas for sectional photoacoustic imaging.

  8. Column Holdup Formula of Soil Solute Transport

    Institute of Scientific and Technical Information of China (English)

    2000-01-01

    The shortcomings of the present two formulae for describing column holdup are analyzed and deductions are made to find a new formula. The column holdup, Hw, described by the new formula is dimensional,and related to soil solute transport kinesis and column physical properties. Compared with the other two column holdups, Hw is feasible to describe dimensional column holdup during solute transport process. The relationships between Hw and retardation factor, R, in different solute transport boundary conditions are established.

The data sample, collected with the CMS detector, corresponds to an integrated luminosity of 19.7[Formula: see text]. The measurement is performed in the lepton+jets channel in which the products of the semileptonic decay [Formula: see text] with [Formula: see text] where [Formula: see text] is an electron or muon, are used to select [Formula: see text] events with large Lorentz boosts. The products of the fully hadronic decay [Formula: see text] with [Formula: see text] are reconstructed using a single Cambridge-Aachen jet with distance parameter [Formula: see text], and [Formula: see text] [Formula: see text]. The [Formula: see text] cross section as a function of [Formula: see text] is unfolded at the particle level and is used to test the modelling of highly boosted top quark production. The peak position of the [Formula: see text] distribution is sensitive to the top quark mass [Formula: see text], and the data are used to extract a value of [Formula: see text] to assess this sensitivity.

  12. Relating Turing's Formula and Zipf's Law

    CERN Document Server

    Samuelsson, C

    1996-01-01

    An asymptote is derived from Turing's local reestimation formula for population frequencies, and a local reestimation formula is derived from Zipf's law for the asymptotic behavior of population frequencies. The two are shown to be qualitatively different asymptotically, but nevertheless to be instances of a common class of reestimation-formula-asymptote pairs, in which they constitute the upper and lower bounds of the convergence region of the cumulative of the frequency function, as rank tends to infinity. The results demonstrate that Turing's formula is qualitatively different from the various extensions to Zipf's law, and suggest that it smooths the frequency estimates towards a geometric distribution.

    The paper presents a design formula for Tetrapod armour on a 1:1.5 slope exposed to head-on random wave attack. The formula predicts the relative number of broken Tetrapods as function of: the mass of the Tetrapods, the concrete tensile strength and the wave height in front of the structure. Thus......, the formula addresses the observed problem of ensuring structural integrity of the slender types of non-reinforced armour units. The formula is based on results from small scale model tests with load-cell instrumented Tetrapods in which both the static, the quasi-static and the impact proportions of the loads...

  14. Mesoscopic formulas of linear and angular momentum fluxes

    Science.gov (United States)

    Fruleux, Antoine; Sekimoto, Ken

    2016-07-01

    Many approaches of coarse graining have been developed under the names of Cosserat theory or polar-fluid theory for those materials in which some component elements undergo nonaffine deformations, such as elastic materials with inclusions or granular matters. For the complex elements such as living cells, however, the microscopic variables and their dynamics are often unknown, and there has been no systematic theory of coarse graining from the microscales nor the formulas like the Irving-Kirkwood formula that constitutes the macroscopic stress or couple stress in terms of some microscale quantities. We show that, for the quasi-steady states, the coarse-graining procedure must generally provide us with the Cosserat-type balance equations as long as the procedure keeps track of the conservation of linear and angular momenta, and that the fluxes of these conserved quantities should generally be expressed in the Irving-Kirkwood-type formulas, where the interparticle distance or forces and torques should be replaced by those associated to the pair of neighboring coarse-graining volumes. This framework, which refers to no particular microvariables or dynamics, is valid for active complex matters out of equilibrium and with any multibody interactions.

  15. Assessment of the breast volume by a new simple formula

    Directory of Open Access Journals (Sweden)

    El-Oteify Mahmoud

    2006-01-01

    Full Text Available Background: With the recent introduction of improved techniques for plastic surgery of the breast and increased public awareness toward these procedures, plastic surgeons are continuously trying to improve their methods and results to reach perfection. Assessment of the breast volume is an important issue prior to the use of breast implants in any aesthetic or reconstructive breast surgery. Previous methods to measure breast volume have included use of a simple bra and breast cup size, cumbersome fluid displacement, appliances and approximate visual estimation. Objectives: In this work we have tried to develop an easy method for assessment of the breast volume for both the patient and the the surgeon through a simple mathematical formula. Materials and Methods: Fifty two volunteers were included in this study. For every one, general parameters including age, weight and height were recorded. Local breast measurements and water volume displacement were also recorded. Results: The collected data were statistically correlated. Using the analyzed data, the breast volume was calculated through a simple and direct formula on the basis of the breast circumference. Conclusion: Our method has, as its principle, the use of an accurate and simple formula, which is based only on one measurement. This is easy for both the patient and the plastic surgeon. This equation is not only a significant technical advantage for the surgeon, but also provides a universal standardization of the breast volume.

  16. Rigorous theoretical constraint on constant negative EoS parameter [Formula: see text] and its effect for the late Universe.

    Science.gov (United States)

    Burgazli, Alvina; Eingorn, Maxim; Zhuk, Alexander

    In this paper, we consider the Universe at the late stage of its evolution and deep inside the cell of uniformity. At these scales, the Universe is filled with inhomogeneously distributed discrete structures (galaxies, groups and clusters of galaxies). Supposing that the Universe contains also the cosmological constant and a perfect fluid with a negative constant equation of state (EoS) parameter [Formula: see text] (e.g., quintessence, phantom or frustrated network of topological defects), we investigate scalar perturbations of the Friedmann-Robertson-Walker metrics due to inhomogeneities. Our analysis shows that, to be compatible with the theory of scalar perturbations, this perfect fluid, first, should be clustered and, second, should have the EoS parameter [Formula: see text]. In particular, this value corresponds to the frustrated network of cosmic strings. Therefore, the frustrated network of domain walls with [Formula: see text] is ruled out. A perfect fluid with [Formula: see text] neither accelerates nor decelerates the Universe. We also obtain the equation for the nonrelativistic gravitational potential created by a system of inhomogeneities. Due to the perfect fluid with [Formula: see text], the physically reasonable solutions take place for flat, open and closed Universes. This perfect fluid is concentrated around the inhomogeneities and results in screening of the gravitational potential.

  17. Pre-hospital care in burn injury

    Shrivastava Prabhat

    2010-10-01

    Full Text Available The care provided to the victims of burn injury immediately after sustaining burns can largely affect the extent and depth of the wound. Although standard guidelines have been formulated by various burn associations, they are still not well known to public at large in our country. In burn injuries, most often, the bystanders are the first care providers. The swift implementation of the measures described in this article for first aid in thermal, chemical, electrical and inhalational injuries in the practical setting, within minutes of sustaining the burn, plays a vital role and can effectively reduce the morbidity and mortality to a great extent. In case of burn disasters, triage needs to be carried out promptly as per the defined protocols. Proper communication and transport from the scene of the accident to the primary care centre and onto the burn care facility greatly influences the execution of the management plans

  1. Body surface area formulae: an alarming ambiguity.

    Science.gov (United States)

    Redlarski, Grzegorz; Palkowski, Aleksander; Krawczuk, Marek

    2016-06-21

    Body surface area (BSA) plays a key role in several medical fields, including cancer chemotherapy, transplantology, burn treatment and toxicology. BSA is often a major factor in the determination of the course of treatment and drug dosage. A series of formulae to simplify the process have been developed. Because easy-to-identify, yet general, body coefficient results of those formulae vary considerably, the question arises as to whether the choice of a particular formula is valid and safe for patients. Here we show that discrepancies between most of the known BSA formulae can reach 0.5 m(2) for the standard adult physique. Although many previous studies have demonstrated that certain BSA formulae provide an almost exact fit with the patients examined, all of these studies have been performed on a limited and isolated group of people. Our analysis presents a broader perspective, considering 25 BSA formulae. The analysis revealed that the choice of a particular formula is a difficult task. Differences among calculations made by the formulae are so great that, in certain cases, they may considerably affect patients' mortality, especially for people with an abnormal physique or for children.

  11. Preclinical assessment of infant formula.

    Science.gov (United States)

    2012-01-01

    Infant formulas are the sole or predominant source of nutrition for many infants and are fed during a sensitive period of development and may therefore have short- and long-term consequences for infant health. Preclinical safety assessment therefore needs to include both short-term and long-term studies in animals. It is recommended that procedures are instituted by which experts may serve as independent scientists for companies developing novel products, without having their integrity compromised, and later serve the legislative institutions. A two-level assessment approach to determine the potential toxicity of a novel ingredient, its metabolites, and their effects in the matrix on developing organ systems has been suggested by IOM. This appears reasonable, as novel ingredients can be of different levels of concern. The use of modern methods in genomics and proteomics should be considered in these evaluation processes as well as novel methods to evaluate outcomes, including metabolomics and molecular techniques to assess the microbiome.

  13. A ``fractal'' modification of Torricelli's formula

    Science.gov (United States)

    Maramathas, Athanasios J.; Boudouvis, Andreas G.

    2010-03-01

    A modification is proposed of Torricelli’s (1608-1647) formula for the velocity of water discharging from a small hole at the bottom of a large tank filled with fractal solid material. The new formula takes proper account of the mechanical energy losses due to flow in the solid matrix, thus expanding the area of validity of the classical Torricelli’s formula. Moreover, it offers a convenient alternative to Darcy’s law for estimating the discharge rate from an aquifer. The new formula was derived from laboratory experiments, with a low-Reynolds number discharge flow (Darcian flow). It was tested in a natural karst aquifer where the flow is non-Darcian, at Almiros spring on the island of Crete (Greece). In both cases, the predictive capability of the modified formula is established.

    2013-01-15

    We derive the Lichnerowicz-Weitzenboeck formula for the two-component order parameter superconductor, which provides a twofold view of the kinetic energy of the superconductor. For the one component order parameter superconductor we review the connection between the Lichnerowicz-Weitzenboeck formula and the Ginzburg-Landau theory. For the two-component case we claim that this formula opens a venue to describe inhomogeneous superconducting states intertwined by spin correlations and charged dislocation. In this case the Lichnerowicz-Weitzenboeck formula displays local rotational and electromagnetic gauge symmetry (SU(2) Circled-Times U(1)) and relies on local commuting momentum and spin operators. The order parameter lives in a space with curvature and torsion described by Elie Cartan geometrical formalism.

    Full Text Available Initial management of severely burned patient is similar with a trauma victim. Determination of airway patency, evaluation of respiration and circulation, early recognition of concomitant trauma has vital importance in burn patients. In the early phase, mortality mainly depends on missed or un-treated severe injuries or pathologies, but not burn injury itself.In patients that have TBSA greater than 15 %, fluid resuscitation should be started. In the first 24 hours, crystalloid solutions should be preferred. .Several formulas can guide fluid resuscitation; however the amount of fluid that is given to the patient should be individualized according to the patient’s need.

  5. Connection formula for thermal density functional theory

    CERN Document Server

    Pribram-Jones, Aurora

    2015-01-01

    The adiabatic connection formula of ground-state density functional theory relates the correlation energy to a coupling-constant integral over a purely potential contribution, and is widely used to understand and improve approximations. The corresponding formula for thermal density functional theory is cast as an integral over temperatures instead, ranging upwards from the system's physical temperature to infinite temperatures. Several formulas yield one component of the thermal correlation free energy in terms of another, many of which can be expressed either in terms of temperature- or coupling-constant integration. We illustrate with the uniform electron gas.

    The eikonal approximation for moderately small scattering amplitudes is considered. With the purpose of using for their numerical estimations, the formulas are derived which contain no Bessel functions, and, hence, no rapidly oscillating integrands. To obtain these formulas, the improper integrals of the first kind which contain products of the Bessel functions J_0(z) are studied. The expression with four functions J_0(z) is generalized. The expressions for the integrals with the product of five and six Bessel functions J_0(z) are also found. The known formula for the improper integral with two functions J_nu(z) is generalized for non-integer nu.

    We consider the eikonal approximation for moderately small scattering amplitudes. To find numerical estimates of these approximations, we derive formulas that contain no Bessel functions and consequently no rapidly oscillating integrands. To obtain these formulas, we study improper integrals of the first kind containing products of the Bessel functions J0(z). We generalize the expression with four functions J0(z) and also find expressions for the integrals with the product of five and six Bessel functions. We generalize a known formula for the improper integral with two functions Jυ (az) to the case with noninteger υ and complex a.

    A dense mixture of granules and liquid often shows a severe shear thickening and is called a dilatant fluid. We construct a fluid dynamics model for the dilatant fluid by introducing a phenomenological state variable for a local state of dispersed particles. With simple assumptions for an equation...... of the state variable, we demonstrate that the model can describe basic features of the dilatant fluid such as the stress-shear rate curve that represents discontinuous severe shear thickening, hysteresis upon changing shear rate, and instantaneous hardening upon external impact. An analysis of the model...... reveals that the shear thickening fluid shows an instability in a shear flow for some regime and exhibits the shear thickening oscillation (i.e., the oscillatory shear flow alternating between the thickened and the relaxed states). The results of numerical simulations are presented for one- and two...

    The present study aims to reveal some facts concerning first language ([Formula: see text] and second language ([Formula: see text] spoken-word processing in unbalanced proficient bilinguals using behavioral measures. The intention here is to examine the effects of auditory repetition word priming and semantic priming in first and second languages of these bilinguals. The other goal is to explore the effects of attention manipulation on implicit retrieval of perceptual and conceptual properties of spoken [Formula: see text] and [Formula: see text] words. In so doing, the participants performed auditory word priming and semantic priming as memory tests in their [Formula: see text] and [Formula: see text]. In a half of the trials of each experiment, they carried out the memory test while simultaneously performing a secondary task in visual modality. The results revealed that effects of auditory word priming and semantic priming were present when participants processed [Formula: see text] and [Formula: see text] words in full attention condition. Attention manipulation could reduce priming magnitude in both experiments in [Formula: see text]. Moreover, [Formula: see text] word retrieval increases the reaction times and reduces accuracy on the simultaneous secondary task to protect its own accuracy and speed.

    2006-01-01

    Hodge integrals over moduli spaces of curves appear naturally during the localization procedure in computation of Gromov-Witten invariants. A remarkable formula of Marino-Vafa expresses a generation function of Hodge integrals via some combinatorial and algebraic data seemingly unrelated to these apriori algebraic geometric objects. We prove in this paper by directly expanding the formula and estimating the involved terms carefully that except a specific type all the other Hodge integrals involving up to three Hodge classes can be calculated from this formula. This implies that amazingly rich information about moduli spaces and Gromov-Witten invariants is encoded in this complicated formula. We also give some low genus examples which agree with the previous results in literature. Proofs and calculations are elementary as long as one accepts Mumford relations on the reductions of products of Hodge classes.

    The development of computer controlled continuous rolling process calls for a mathematicalexpression that can express the inequality condition of "constant flow". Tension is the link of thecontinuous rolling process. From the condition of dynamic equilibrium, a differential equation oftension is given out. On the basis of the physical rules established from the industrial practice andexperimental studies, the law of volume constancy, the linear relation of forward slip and tension,the state equation of continuous rolling, the formula of dynamic tension, and the formula of statictension have been obtained. These formulae reflect the functional relations between tensions,thickness, roll velocity, and time in the continuous rolling process. It is implied that the continuousrolling process is a gradually steady, controllable, and measurable dynamic system. An assumptionof predicting the thickness of a steel plate using these tension formulae is also put forward.

    Euler Number is one of the most important characteristics in topology. In two- dimension digital images, the Euler characteristic is locally computable. The form of Euler Number formula is different under 4-connected and 8-connected conditions. Based on the definition of the Foreground Segment and Neighbor Number, a formula of the Euler Number computing is proposed and is proved in this paper. It is a new idea to locally compute Euler Number of 2D image.

    We generalize Macdonald's formula for the cohomology of Hilbert schemes of points on a curve from smooth curves to curves with planar singularities: we relate the cohomology of the Hilbert schemes to the cohomology of the compactified Jacobian of the curve. The new formula is a consequence of a stronger identity between certain perverse sheaves defined by a family of curves satisfying mild conditions, whose proof makes an essential use of Ng\\^o's support theorem for compactified Jacobians.

    We treat the problem of normally ordering expressions involving the standard boson operators a, a* where [a,a*]=1. We show that a simple product formula for formal power series - essentially an extension of the Taylor expansion - leads to a double exponential formula which enables a powerful graphical description of the generating functions of the combinatorial sequences associated with such functions - in essence, a combinatorial field theory. We apply these techniques to some examples related to specific physical Hamiltonians.

    2015-01-01

    This book presents a focused, readable account of the principal physical and mathematical ideas at the heart of fluid dynamics. Graduate students in engineering, applied math, and physics who are taking their first graduate course in fluids will find this book invaluable in providing the background in physics and mathematics necessary to pursue advanced study. The book includes a detailed derivation of the Navier-Stokes and energy equations, followed by many examples of their use in studying the dynamics of fluid flows. Modern tensor analysis is used to simplify the mathematical derivations, thus allowing a clearer view of the physics. Peter Bernard also covers the motivation behind many fundamental concepts such as Bernoulli's equation and the stream function. Many exercises are designed with a view toward using MATLAB or its equivalent to simplify and extend the analysis of fluid motion including developing flow simulations based on techniques described in the book.

    Witten's twistor string theory has led to new representations of S-matrix in massless QFT as a single object, including Cachazo-He-Yuan formulas in general and connected formulas in four dimensions. As a first step towards more realistic processes of the standard model, we extend the construction to QCD tree amplitudes with massless quarks and those with a Higgs boson. For both cases, we find connected formulas in four dimensions for all multiplicities which are very similar to the one for Yang-Mills amplitudes. The formula for quark-gluon color-ordered amplitudes differs from the pure-gluon case only by a Jacobian factor that depends on flavors and orderings of the quarks. In the formula for Higgs plus multi-parton amplitudes, the massive Higgs boson is effectively described by two additional massless legs which do not appear in the Parke-Taylor factor. The latter also represents the first twistor-string/connected formula for form factors.

    Full Text Available Ana Močić Pavić, Iva Hojsak Referral Center for Pediatric Gastroenterology and Nutrition, Children's Hospital Zagreb, Zagreb, Croatia Background: In recent years prebiotics have been added to infant formula to make it resemble breast milk more closely and to promote growth and development of beneficial intestinal microbiota. This review aims to present new data on the possible positive effects of prebiotics in infant formula on intestinal microbiota (bifidogenic and lactogenic effect and on clinical outcomes including growth, infections, and allergies. With that aim, a literature search of the Cochrane Central Register of Controlled Trials (CENTRAL, EMBASE, Scopus, PubMed/Medline, Web of Science, and Science Direct in the last 10 years (December 2003 to December 2013 was performed. Results: Altogether 24 relevant studies were identified. It was found that during intervention, prebiotics can elicit a bifidogenic and lactogenic effect. As far as clinical outcomes were concerned, 14 studies investigated the effect of infant formula supplemented with prebiotics on growth and found that there was no difference when compared with non-supplemented infant formula. All available data are insufficient to support prebiotic supplementation in order to reduce risk of allergies and infections. Conclusion: There is currently no strong evidence to recommend routine supplementation of infant formulas with prebiotics. Further well-designed clinical studies with long-term follow-up are needed. Keywords: prebiotics, infant formula, growth, allergy, infections, supplementation

  10. New formulae between Jacobi polynomials and some fractional Jacobi functions generalizing some connection formulae

    Abd-Elhameed, W. M.

    2017-07-01

    In this paper, a new formula relating Jacobi polynomials of arbitrary parameters with the squares of certain fractional Jacobi functions is derived. The derived formula is expressed in terms of a certain terminating hypergeometric function of the type _4F3(1) . With the aid of some standard reduction formulae such as Pfaff-Saalschütz's and Watson's identities, the derived formula can be reduced in simple forms which are free of any hypergeometric functions for certain choices of the involved parameters of the Jacobi polynomials and the Jacobi functions. Some other simplified formulae are obtained via employing some computer algebra algorithms such as the algorithms of Zeilberger, Petkovsek and van Hoeij. Some connection formulae between some Jacobi polynomials are deduced. From these connection formulae, some other linearization formulae of Chebyshev polynomials are obtained. As an application to some of the introduced formulae, a numerical algorithm for solving nonlinear Riccati differential equation is presented and implemented by applying a suitable spectral method.

  11. Holographic Fluids with Vorticity and Analogue Gravity

    2012-01-01

    We study holographic three-dimensional fluids with vorticity in local equilibrium and discuss their relevance to analogue gravity systems. The Fefferman-Graham expansion leads to the fluid's description in terms of a comoving and rotating Papapetrou-Randers frame. A suitable Lorentz transformation brings the fluid to the non-inertial Zermelo frame, which clarifies its interpretation as moving media for light/sound propagation. We apply our general results to the Lorentzian Kerr-AdS_4 and Taub-NUT-AdS_4 geometries that describe fluids in cyclonic and vortex flows respectively. In the latter case we associate the appearance of closed timelike curves to analogue optical horizons. In addition, we derive the classical rotational Hall viscosity of three-dimensional fluids with vorticity. Our formula remarkably resembles the corresponding result in magnetized plasmas.

    Recent interest in shortening the fasting interval after ingestion of milk products demonstrated large volumes of breast milk in the stomach 2 h after breastfeeding. Although aspiration is a rare event, if it were to occur with human breast milk, it is important to understand the extent of the lung injury that might occur. Therefore, the response to instillation of acidified breast milk and infant formula in the lungs of adult rabbits was studied. In 18 anesthetized adult rabbits, 1 of 3 fluids (in a volume of 0.8 ml.kg-1 and pH level of 1.8, acidified with hydrochloric acid); saline, breast milk, or infant formula (SMA, Wyeth, Windsor, Ontario), was instilled into the lungs via a tracheotomy. The lungs were ventilated for 4 h after instillation. Alveolar-to-arterial oxygen gradient and dynamic compliance were measured before and at hourly intervals after instillation. After 4 h, the rabbits were killed and the lungs were excised. Neutrophil infiltration was quantitated by a pathologist blinded to the instilled fluid. A histologic control group of four rabbits was ventilated under study conditions without any intratracheal fluid instillation. Alveolar-to-arterial oxygen gradient increased and dynamic compliance decreased significantly during the 4 h after instillation of both breast milk and infant formula compared with baseline measurements and with saline controls (P formula rabbits were significantly greater than those in the control group. Instillation of acidified breast milk or infant formula (in a volume of 0.8 ml.kg-1 and pH level of 1.8) into rabbits' lungs induces acute lung injury of similar intensity that lasts at least 4 h.

    Several different protein hydrolysate-based infant formulas have been promoted as hypoallergenic and considered suitable for the dietary management of cow's milk allergy (CMA). Accepting that none of the hydrolysate-based products is completely safe, the American Academy of Pediatrics (AAP) recommends that these formulas should be tested in a double-blind placebo-controlled setting and tolerated by at least 90% of children with proven CMA. In principle, this recommendation is also endorsed by the European Society of Paediatric Gastroenterology and Nutrition (ESPGAN) and the European Society of Paediatric Allergy and Clinical Immunology (ESPACI). In this two-center study, 32 children with proven CMA were tested with the extensive hydrolysate whey formula Nutrilon Pepti, for comparison with Profylac (extensive) and Nan HA (partial) whey hydrolysate products. Skin-prick tests (SPTs) were, respectively, positive to the three hydrolysate formulas in 19%, 15%, and 32% of children. After oral challenge it was concluded that 97% (95% CI: 85-100%) of the children tolerated Nutrilon Pepti, 94% (95% CI: 75-100%) tolerated Profylac, and 64% (95% CI: 37-81%) tolerated Nan HA. This study demonstrates that the extensive hydrolysates Nutrilon Pepti and Profylac are well tolerated in a population of children with proven CMA and that both products can be considered safe for their intended use. This study confirms that a very small number of children react even to extensively hydrolyzed formulas. SPT prior to oral exposure to the hydrolysate-based formulas can indicate whether a child is at risk of showing reactions to the product. Introduction of new products to these children should be carried out under a doctor's supervision. However, the majority of the SPT-positive children did tolerate the two extensively hydrolyzed whey-based formulas tested.

    2016-01-01

    Breast milk is a dynamic fluid with compositional changes occurring throughout the period of lactation. Some of these changes in nutrient concentrations reflect the successively slowing growth rate and developmental changes in metabolic requirements that infants undergo during the first year of life. Infant formula, in contrast, has a static composition, intended to meet the nutritional requirements of infants from birth to 6 or 12 months of age. To better fit the metabolic needs of infants and to avoid nutrient limitations or excesses, we suggest that infant formulas should change in composition with the age of the infant, that is, different formulas are created/used for different ages during the first year of life. We propose that specific formulas for 0 to 3 months (stage 1), 3 to 6 months (stage 2), and 6 to 12 months (stage 3) of age may be nutritionally and physiologically advantageous to infants. Although this initially may impose some difficult practical/conceptual issues, we believe that this staging concept would improve nutrition of formula-fed infants and, ultimately, improve outcomes and make their performance more similar to that of breast-fed infants.

    Full Text Available Hypernatremic dehydration is a rare but serious clinical condition in newborns and small infants. It is usually caused by diarrhea, improperly prepared infant formula, decreased fluid intake, or exclusive breastfeeding. Symptoms are usually masked until neurological symptoms occur. We report two infants who presented with fever and hypernatremic dehydration caused by concentrating infant formula to alleviate symptoms of constipation, and careless formula preparation due to confusion over spoon sizes, respectively. In the first case, status epilepticus occurred during early treatment, despite close serum sodium monitoring, though the infant was asymptomatic and thriving 4 years after discharge, with no identified neurodevelopmental deficits. The course of treatment was smooth in the second case, and no neurological complications developed. The practice of concentrating infant formula to relieve symptoms of constipation, although temporarily effective, is hazardous to newborns or young infants and can cause hypernatremic dehydration. Spoon sizes supplied with commercial infant formulas (30 mL/spoonful or 60 mL/spoonful should be unified to avoid mistakes during preparation, especially by inexperienced and teenage mothers.

    Introduction. NASA's Human Research Program is focused on addressing health risks associated with long-duration missions on the International Space Station (ISS) and future exploration-class missions beyond low Earth orbit. Visual acuity changes observed after short-duration missions were largely transient, but now more than 50 percent of ISS astronauts have experienced more profound, chronic changes with objective structural findings such as optic disc edema, globe flattening and choroidal folds. These structural and functional changes are referred to as the visual impairment and intracranial pressure (VIIP) syndrome. Development of VIIP symptoms may be related to elevated intracranial pressure (ICP) secondary to spaceflight-induced cephalad fluid shifts, but this hypothesis has not been tested. The purpose of this study is to characterize fluid distribution and compartmentalization associated with long-duration spaceflight and to determine if a relation exists with vision changes and other elements of the VIIP syndrome. We also seek to determine whether the magnitude of fluid shifts during spaceflight, as well as any VIIP-related effects of those shifts, are predicted by the crewmember's pre-flight status and responses to acute hemodynamic manipulations, specifically posture changes and lower body negative pressure. Methods. We will examine a variety of physiologic variables in 10 long-duration ISS crewmembers using the test conditions and timeline presented in the figure below. Measures include: (1) fluid compartmentalization (total body water by D2O, extracellular fluid by NaBr, intracellular fluid by calculation, plasma volume by CO rebreathe, interstitial fluid by calculation); (2) forehead/eyelids, tibia, and calcaneus tissue thickness (by ultrasound); (3) vascular dimensions by ultrasound (jugular veins, cerebral and carotid arteries, vertebral arteries and veins, portal vein); (4) vascular dynamics by MRI (head/neck blood flow, cerebrospinal fluid

    The theory of explicit formulas for regularized products and series forms a natural continuation of the analytic theory developed in LNM 1564. These explicit formulas can be used to describe the quantitative behavior of various objects in analytic number theory and spectral theory. The present book deals with other applications arising from Gaussian test functions, leading to theta inversion formulas and corresponding new types of zeta functions which are Gaussian transforms of theta series rather than Mellin transforms, and satisfy additive functional equations. Their wide range of applications includes the spectral theory of a broad class of manifolds and also the theory of zeta functions in number theory and representation theory. Here the hyperbolic 3-manifolds are given as a significant example.

    The Langlands Program relates Galois representations and automorphic representations of reductive algebraic groups. The trace formula is a powerful tool in the study of this connection and the Langlands Functoriality Conjecture. After giving an introduction to the Langlands Program and its geometric version, which applies to curves over finite fields and over the complex field, I give a survey of my recent joint work with Robert Langlands and Ngo Bao Chau (arXiv:1003.4578 and arXiv:1004.5323) on a new approach to proving the Functoriality Conjecture using the trace formulas, and on the geometrization of the trace formulas. In particular, I discuss the connection of the latter to the categorification of the Langlands correspondence.

    We present a special-relativistic analysis of deformable interferometers where counter propagating beams share a common optical path. The optical path is allowed to change rather arbitrarily and need not be stationary. We show that, in the absence of dispersion the phase shift has two contributions. To leading order in $v/c$ one contribution is given by Wang empirical formula for deformable Sagnac interferometers. The second contribution is due to the stretching of the optical path and we give an explicit formula for this stretch term valid to first order in $v/c$. The analysis provides a unifying framework incorporating the Sagnac, Wang and Fizeau effects in a single scheme and gives a rigorous proof of Wang empirical formula.

    Full Text Available In logic, representation of a domain (e.g., physical reality comprises the things its expressions (formulas refer to and their relationships. Recent research has examined the realm of nonsymbolic representations, especially diagrams. It is claimed that, in general, diagrams have advantages over linguistic descriptions. Current diagrammatic representations of logic formulas do not completely depict their underlying semantics, and they lack a basic static structure that incorporates elementary dynamic features, creating a conceptual gap that can lead to misinterpretation. This paper demonstrates a methodology for mapping the sense of a logic formula and producing diagrams that integrate linguistic conception, truth-values, and meaning and can be used in teaching, communication, and understanding, especially with students specializing in logic representation and reasoning.

    Random Boolean formulae, generated by a growth process of noisy logical gates are analyzed using the generating functional methodology of statistical physics. We study the type of functions generated for different input distributions, their robustness for a given level of gate error and its dependence on the formulae depth and complexity and the gates used. Bounds on their performance, derived in the information theory literature for specific gates, are straightforwardly retrieved, generalized and identified as the corresponding typical-case phase transitions. Results for error-rates, function-depth and sensitivity of the generated functions are obtained for various gate-type and noise models.

    2016-11-01

    A new method computing Campbell-Hausdorff formula is proposed by using quantum moment-cumulant relations, which is given by Weyl ordering symmetrization of classical moment-cumulant relations. The method enables one to readily use symbolic language software to compute arbitrary terms in the formula, and explicit expressions up to the 6-th order are obtained by the way of illustration. Further the symmetry Codd(A, B) = Codd(B, A), Ceven(A, B) = - Ceven(B, A) is found and proved. The operator differential method by Knapp is also examined for the comparison.

    2016-06-01

    Full Text Available Ship squat is a combined effect of ship’s draft and trim increase due to ship motion in limited navigation conditions. Over time, researchers conducted tests on models and ships to find a mathematical formula that can define squat. Various forms of calculating squat can be found in the literature. Among those most commonly used are of Barrass, Millward, Eryuzlu or ICORELS. This paper presents a comparison between the squat formulas to see the differences between them and which one provides the most satisfactory results. In this respect a cargo ship at different speeds was considered as a model for maximum squat calculations in canal navigation conditions.

    Full Text Available This work implements and evaluates the recent complete addition formulae for the prime order elliptic curves of Renes, Costello and Batina on an FPGA platform. We implement three different versions:(1 an unprotected architecture; (2 an architecture protected through coordinate randomization; and (3 an architecture with both coordinate randomization and scalar splitting in place. The evaluation is done through timing analysis and test vector leakage assessment (TVLA. The results show that applying an increasing level of countermeasures leads to an increasing resistance against side-channel attacks. This is the first work looking into side-channel security issues of hardware implementations of the complete formulae.

    The accurate computation of radiative opacities is basic in the ICF target physics analysis, in which the radiation is an important feature to determine in detail. For this reason, accurate analytical formulas for giving mean opacities versus temperature and density of the plasma seem to be a useful tool. In this work we analyse some analytical expressions found in the literature for the opacity low Z plasmas in a wide range of temperature and densities. The validity of these formulas for computing the opacity under NLTE conditions is investigated using the new code ABAKO.

  1. Calculation of the CIPW norm: New formulas

    Pruseth, Kamal L.

    2009-02-01

    A completely new set of formulas, based on matrix algebra, has been suggested for the calculation of the CIPW norm for igneous rocks to achieve highly consistent and accurate norms. The suggested sequence of derivation of the normative minerals greatly deviates from the sequence followed in the classical scheme. The formulas are presented in a form convenient for error-free implementation in computer programs. Accurate formulas along with the use of variable molecular weights for CaO and FeO; corrected formula weights for apatite, pyrite and fluorite; and suggested measures to avoid significant rounding off errors to achieve absolute match between the sum of the input weights of the oxides and the sum of the weights of the estimated normative minerals. Using an analogous procedure for determining the oxidation ratios of igneous rocks as used in the SINCLAS system of Verma et al (2002, 2003), the suggested calculation scheme exactly reproduces their results except for apatite for reasons explained in the text, but with a superior match between the totals for about 11,200 analyses representing rocks of a wide range of composition

    2016-03-01

    Since breastfeeding is not always possible, infant formulas (IFs) are supplemented with prebiotic oligosaccharides, such as galactooligosaccharides (GOS) and/or fructooligosaccharides (FOS) to exert similar effects to those of the breast milk. Nowadays, a great number of infant formulas enriched with prebiotics are disposal in the market, however there are scarce data about their composition. In this study, the combined use of two chromatographic methods (GC-FID and HPLC-RID) for the quantification of carbohydrates present in commercial infant formulas have been used. According to the results obtained by GC-FID for products containing prebiotics, the content of FOS, GOS and GOS/FOS was in the ranges of 1.6-5.0, 1.7-3.2, and 0.08-0.25/2.3-3.8g/100g of product, respectively. HPLC-RID analysis allowed quantification of maltodextrins with degree of polymerization (DP) up to 19. The methodology proposed here may be used for routine quality control of infant formula and other food ingredients containing prebiotics.

  16. Formula management: in search of magic solutions.

    Science.gov (United States)

    McConnell, C R

    1997-12-01

    Formula management is the unjustified reliance on a set of rules or prescribed behaviors--a management formula, fad, or "flavor-of-the-month"--as the answer to an organization's needs. It is the manifestation of a tendency to believe that the essence of management can be proceduralized, that the art of management can be replaced with an expanding science of management. This tendency has been repeatedly demonstrated in the application of concepts such as management by objectives (MBO) and the variants of total quality management (TQM). All of management's "formulas" have their place; however, none of them provide all of management's needed answers. To view any of the specifically delineated "kinds of management"--all of which are highly susceptible to misapplication and resistance to change both blatant and subtle--as a cure-all is fully as inappropriate as denying their value out of hand. Formula or not, organizational results will continue to depend on the practice of the art, as well as the science, of management.

    The production of K[Formula: see text](892)[Formula: see text] and [Formula: see text](1020) mesons has been measured in p-Pb collisions at [Formula: see text][Formula: see text] 5.02 TeV. K[Formula: see text] and [Formula: see text] are reconstructed via their decay into charged hadrons with the ALICE detector in the rapidity range [Formula: see text]. The transverse momentum spectra, measured as a function of the multiplicity, have a p[Formula: see text] range from 0 to 15 GeV/c for K[Formula: see text] and from 0.3 to 21 GeV/c for [Formula: see text]. Integrated yields, mean transverse momenta and particle ratios are reported and compared with results in pp collisions at [Formula: see text][Formula: see text] 7 TeV and Pb-Pb collisions at [Formula: see text][Formula: see text] 2.76 TeV. In Pb-Pb and p-Pb collisions, K[Formula: see text] and [Formula: see text] probe the hadronic phase of the system and contribute to the study of particle formation mechanisms by comparison with other identified hadrons. For this purpose, the mean transverse momenta and the differential proton-to-[Formula: see text] ratio are discussed as a function of the multiplicity of the event. The short-lived K[Formula: see text] is measured to investigate re-scattering effects, believed to be related to the size of the system and to the lifetime of the hadronic phase.

  2. Dissipative charged fluid in a magnetic field

    Directory of Open Access Journals (Sweden)

    Navid Abbasi

    2016-05-01

    Full Text Available We study the collective excitations in a dissipative charged fluid at zero chemical potential when an external magnetic field is present. While in the absence of magnetic field, four collective excitations appear in the fluid, we find five hydrodynamic modes here. This implies that the magnetic field splits the degeneracy between the transverse shear modes. Using linear response theory, we then compute the retarded response functions. In particular, it turns out that the correlation between charge and the energy fluctuations will no longer vanish, even at zero chemical potential. By use of the response functions, we also derive the relevant Kubo formulas for the transport coefficients.

  3. Fluid dynamics

    CERN Document Server

    Ruban, Anatoly I

    This is the first book in a four-part series designed to give a comprehensive and coherent description of Fluid Dynamics, starting with chapters on classical theory suitable for an introductory undergraduate lecture course, and then progressing through more advanced material up to the level of modern research in the field. The present Part 1 consists of four chapters. Chapter 1 begins with a discussion of Continuum Hypothesis, which is followed by an introduction to macroscopic functions, the velocity vector, pressure, density, and enthalpy. We then analyse the forces acting inside a fluid, and deduce the Navier-Stokes equations for incompressible and compressible fluids in Cartesian and curvilinear coordinates. In Chapter 2 we study the properties of a number of flows that are presented by the so-called exact solutions of the Navier-Stokes equations, including the Couette flow between two parallel plates, Hagen-Poiseuille flow through a pipe, and Karman flow above an infinite rotating disk. Chapter 3 is d...

  4. Anisotropic thermal conductivity of magnetic fluids

    2009-01-01

    Considering the forces acting on the particles and the motion of the particles, this study uses a numerical simulation to investigate the three-dimensional microstructure of the magnetic fluids in the presence of an external magnetic field. A method is proposed for predicting the anisotropic thermal conductivity of magnetic fluids. By introducing an anisotropic structure parameter which characterizes the non-uniform distribution of particles suspended in the magnetic fluids, the traditional Maxwell formula is modified and extended to calculate anisotropic thermal conductivity of the magnetic fluids. The results show that in the presence of an external magnetic field the magnetic nanoparticles form chainlike clusters along the direction of the external magnetic field, which leads to the fact that the thermal conduc-tivity of the magnetic fluid along the chain direction is bigger than that along other directions. The thermal conductivity of the magnetic fluids presents an anisotropic feature. With the increase of the magnetic field strength the chainlike clusters in the magnetic fluid appear to be more obvious, so that the anisotropic feature of heat conduction in the fluids becomes more evident.

  5. Graphical representation of QT rate correction formulae: an aid facilitating the use of a given formula and providing a visual comparison of the impact of different formulae.

    Rowlands, Derek J

    2012-01-01

    The QT interval on the electrocardiogram is an increasingly important measurement, especially in relation to drug action and interaction. The QT interval varies inversely as the heart rate and numerous rate correction formulae have been proposed. It is difficult to compare the effect of applying different formulae at different heart rates and for different measured QT intervals. A simple graphical display of the results from different formulae is proposed. This display is dependent on the concept of the absolute correction factor. This graphical presentation is useful (a) in comparing the effect of the application of different formulae and (b) in directly reading the correction produced by any individual formula.

  6. Adaptive dispersion formula for index interpolation and chromatic aberration correction.

    2014-01-13

    This paper defines and discusses a glass dispersion formula that is adaptive. The formula exhibits superior convergence with a minimum number of coefficients. Using this formula we rationalize the correction of chromatic aberration per spectrum order. We compare the formula with the Sellmeier and Buchdahl formulas for glasses in the Schott catalogue. The six coefficient adaptive formula is found to be the most accurate with an average maximum index of refraction error of 2.91 × 10(-6) within the visible band.

  8. Message passing for quantified Boolean formulas

    Zhang, Pan; Zdeborová, Lenka; Zecchina, Riccardo

    2012-01-01

    We introduce two types of message passing algorithms for quantified Boolean formulas (QBF). The first type is a message passing based heuristics that can prove unsatisfiability of the QBF by assigning the universal variables in such a way that the remaining formula is unsatisfiable. In the second type, we use message passing to guide branching heuristics of a Davis-Putnam Logemann-Loveland (DPLL) complete solver. Numerical experiments show that on random QBFs our branching heuristics gives robust exponential efficiency gain with respect to the state-of-art solvers. We also manage to solve some previously unsolved benchmarks from the QBFLIB library. Apart from this our study sheds light on using message passing in small systems and as subroutines in complete solvers.

  9. Clause Elimination Procedures for CNF Formulas

    Science.gov (United States)

    Heule, Marijn; Järvisalo, Matti; Biere, Armin

    We develop and analyze clause elimination procedures, a specific family of simplification techniques for conjunctive normal form (CNF) formulas. Extending known procedures such as tautology, subsumption, and blocked clause elimination, we introduce novel elimination procedures based on hidden and asymmetric variants of these techniques. We analyze the resulting nine (including five new) clause elimination procedures from various perspectives: size reduction, BCP-preservance, confluence, and logical equivalence. For the variants not preserving logical equivalence, we show how to reconstruct solutions to original CNFs from satisfying assignments to simplified CNFs. We also identify a clause elimination procedure that does a transitive reduction of the binary implication graph underlying any CNF formula purely on the CNF level.

  10. Asymptotic sampling formulae for Lambda-coalescents

    CERN Document Server

    Berestycki, Julien; Limic, Vlada

    2012-01-01

    We present a robust method which translates information on the speed of coming down from infinity of a genealogical tree into sampling formulae for the underlying population. We apply these results to population dynamics where the genealogy is given by a Lambda-coalescent. This allows us to derive an exact formula for the asymptotic behavior of the site and allele frequency spectrum and the number of segregating sites, as the sample size tends to infinity. Some of our results hold in the case of a general Lambda-coalescent that comes down from infinity, but we obtain more precise information under a regular variation assumption. In this case, we obtain results of independent interest for the time at which a mutation uniformly chosen at random was generated. This exhibits a phase transition at \\alpha=3/2, where \\alpha \\in(1,2) is the exponent of regular variation.

  11. Universality of Mixed Action Extrapolation Formulae

    CERN Document Server

    Chen, Jiunn-Wei; Walker-Loud, Andre

    2009-01-01

    Mixed action theories with chirally symmetric valence fermions exhibit very desirable features both at the level of the lattice calculations as well as in the construction and implementation of the low energy mixed action effective field theory. In this work we show that when the mixed action effective field theory is projected onto the valence sector, both the Lagrangian and the extrapolation formulae become universal in form through next to leading order, for all variants of discretization methods used for the sea fermions. This implies that for all sea quark methods which are in the same universality class as QCD, the numerical values of the physical coefficients in the various mixed action chiral Lagrangians will be the same up to perturbative lattice spacing dependent corrections. This allows us to construct a prescription to determine the mixed action extrapolation formulae for a large class of hadronic correlation functions computed in partially quenched chiral perturbation theory at the one-loop level...

  12. Inclusion probability with dropout: an operational formula.

    Science.gov (United States)

    Milot, E; Courteau, J; Crispino, F; Mailly, F

    2015-05-01

    In forensic genetics, a mixture of two or more contributors to a DNA profile is often interpreted using the inclusion probabilities theory. In this paper, we present a general formula for estimating the probability of inclusion (PI, also known as the RMNE probability) from a subset of visible alleles when dropouts are possible. This one-locus formula can easily be extended to multiple loci using the cumulative probability of inclusion. We show that an exact formulation requires fixing the number of contributors, hence to slightly modify the classic interpretation of the PI. We discuss the implications of our results for the enduring debate over the use of PI vs likelihood ratio approaches within the context of low template amplifications.

    Samyn, M; Heenen, P H; Pearson, J M; Tondeur, F

    2002-01-01

    In order to have more reliable predictions of nuclear masses at the neutron drip line, we here go beyond the recent mass formula HFBCS-1 and present a new mass formula, HFB-1, based on the Hartree-Fock-Bogoliubov method. As with the HFBCS-1 mass formula, we use a 10-parameter Skyrme force along with a 4-parameter delta-function pairing force and a 2-parameter phenomenological Wigner term. However, with the original HFBCS-1 Skyrme force (MSk7), the rms error becomes unacceptably large and a new force fit is required. With the isoscalar and isovector effective masses constrained to be equal, the remaining 15 degrees of freedom are fitted to the masses of all the 1754 measured nuclei with A>=16, |N-Z|>2 given in the 1995 Audi-Wapstra compilation. The rms error with respect to the masses of all the 1888 measured nuclei with Z,N>=8 is 0.764 MeV. A complete mass table, HFB-1 (available on the Web), has been constructed, giving all nuclei lying between the two drip lines over the range Z,N>=8 and Z<=120. A compar...

    Soy formula (SF) has been fed to millions of infants worldwide. It has been shown to promote growth and development as well as milk-based formula (MF). Controversy has developed over the adequacy and safety of SF. Most concerns are based on in vivo and in vitro data that raise the possibility of estrogenic effects of isoflavones contained in SF. There are few studies of children who were fed SF, and thus insufficient data are available to judge if SF feeding results in clinically significant developmental effects and if there are any long-term health consequences (adverse or beneficial). However, the Arkansas Children's Nutrition Center is conducting a prospective longitudinal study comparing growth, development, and health of breastfed children with formula-fed (SF and MF) children from birth through age 6 y. After 5 y of study, children in all 3 groups (n > 300) are growing and developing within normal limits, and there are no indications of adverse effects in the soy-fed children. Neonatal pig studies comparing SF, MF, and breast milk (BM) have shown diet-specific gene expression profiles in various target tissues. Therefore, although SF differed significantly from BM, MF also differed from BM, and SF differed from MF. Nonetheless, these animals grew and developed normally, and SF piglets had several health benefits (eg, increased bone quality) and no observable adverse effects. Thus, to date, our results suggest that SF supports normal growth and may have advantages in promoting bone development.

  8. The management of central diabetes insipidus in infancy: desmopressin, low renal solute load formula, thiazide diuretics.

    Infants consume most of their calories as formula. Because of this large fluid intake, infants normally produce dilute urine, not far off from that seen in individuals with diabetes insipidus (DI). Infants with DI are therefore prone to water intoxication if fixed antidiuresis is achieved using the long-acting vasopressin analog desmopressin (DDAVP), which induces a state of high urine concentration. DI treatment approaches applied to older children and adults, who consume the their calories as solids, are difficult to apply to infants with DI. When used in infants, oral and intranasal DDAVP can be associated with wide swings in serum sodium concentration (SNA). In comparison, precisely administered subcutaneous doses of DDAVP can be successfully used in infants with DI, and appear to be superior to oral or intranasal DDAVP therapy. Alternatively, consistent eunatremia can be simply achieved in infantile DI using low renal solute load (RSL) formula and thiazide diuretics. Low RSL formula reduces obligatory urinary water losses, and thiazide diuretics concentrate the urine to levels seen in normal formula-fed infants. This report addresses treatment options of DI in infancy and the delicate management issues involved.

    2011-03-28

    We discuss a family of multi-term addition formulae for Weierstrass functions on specialized curves of low genus with many automorphisms, concentrating mostly on the case of genus 1 and 2. In the genus 1 case, we give addition formulae for the equianharmonic and lemniscate cases, and in genus 2 we find some new addition formulae for a number of curves.

  13. Ultradiscrete soliton equations derived from ultradiscrete permanent formulae

    2011-07-22

    We propose formulae of ultradiscrete permanent. Utilizing the formulae, ultradiscrete soliton equations and their multi-soliton solutions are obtained by a simple process. Changing variables and parameters of the formulae, we can derive the ultradiscrete Toda, KdV and hungry Lotka-Volterra equations. An extended version of the ultradiscrete hungry Lotka-Volterra equation is also proposed.

    The production of the [Formula: see text] state in proton-proton collisions is probed via its decay to the [Formula: see text] final state with the LHCb detector, in the rapidity range [Formula: see text] and in the meson transverse-momentum range [Formula: see text]. The cross-section for prompt production of [Formula: see text] mesons relative to the prompt [Formula: see text] cross-section is measured, for the first time, to be [Formula: see text] at a centre-of-mass energy [Formula: see text] using data corresponding to an integrated luminosity of 0.7 fb[Formula: see text], and [Formula: see text] at [Formula: see text] using 2.0 fb[Formula: see text]. The uncertainties quoted are, in order, statistical, systematic, and that on the ratio of branching fractions of the [Formula: see text] and [Formula: see text] decays to the [Formula: see text] final state. In addition, the inclusive branching fraction of [Formula: see text]-hadron decays into [Formula: see text] mesons is measured, for the first time, to be [Formula: see text], where the third uncertainty includes also the uncertainty on the [Formula: see text] inclusive branching fraction from [Formula: see text]-hadron decays.

    Jet multiplicity distributions in top quark pair ([Formula: see text]) events are measured in pp collisions at a centre-of-mass energy of 8 TeV with the CMS detector at the LHC using a data set corresponding to an integrated luminosity of 19.7[Formula: see text]. The measurement is performed in the dilepton decay channels ([Formula: see text], [Formula: see text], and [Formula: see text]). The absolute and normalized differential cross sections for [Formula: see text] production are measured as a function of the jet multiplicity in the event for different jet transverse momentum thresholds and the kinematic properties of the leading additional jets. The differential [Formula: see text] and [Formula: see text] cross sections are presented for the first time as a function of the kinematic properties of the leading additional [Formula: see text] jets. Furthermore, the fraction of events without additional jets above a threshold is measured as a function of the transverse momenta of the leading additional jets and the scalar sum of the transverse momenta of all additional jets. The data are compared and found to be consistent with predictions from several perturbative quantum chromodynamics event generators and a next-to-leading order calculation.

    We present new addition formulae for the Weierstrass functions associated with a general elliptic curve. We prove the structure of the formulae in n-variables and give the explicit addition formulae for the 2- and 3-variable cases. These new results were inspired by new addition formulae found in the case of an equianharmonic curve, which we can now observe as a specialization of the results here. The new formulae, and the techniques used to find them, also follow the recent work for the generalization of Weierstrass functions to curves of higher genus.

    Aerodynamic characteristics of a vehicle are important elements in its design and construction. A low drag coefficient brings significant fuel savings and increased engine power efficiency. In designing and developing vehicles trough computer simulation process to determine the vehicles aerodynamic characteristics are using dedicated CFD (Computer Fluid Dynamics) software packages. However, the results obtained by this faster and cheaper method, are validated by experiments in wind tunnels tests, which are expensive and were complex testing equipment are used in relatively high costs. Therefore, the emergence and development of new low-cost testing methods to validate CFD simulation results would bring great economic benefits for auto vehicles prototyping process. This paper presents the initial development process of a Formula SAE Student race-car prototype using CFD simulation and also present a measurement system based on low-cost sensors through which CFD simulation results were experimentally validated. CFD software package used for simulation was Solid Works with the FloXpress add-on and experimental measurement system was built using four piezoresistive force sensors FlexiForce type.

  1. The chemical formula of a magnetotactic bacterium.

    Elucidation of the chemical logic of life is one of the grand challenges in biology, and essential to the progress of the upcoming field of synthetic biology. Treatment of microbial cells explicitly as a "chemical" species in controlled reaction (growth) environments has allowed fascinating discoveries of elemental formulae of a few species that have guided the modern views on compositions of a living cell. Application of mass and energy balances on living cells has proved to be useful in modeling of bioengineering systems, particularly in deriving optimized media compositions for growing microorganisms to maximize yields of desired bio-derived products by regulating intra-cellular metabolic networks. In this work, application of elemental mass balance during growth of Magnetospirillum gryphiswaldense in bioreactors has resulted in the discovery of the chemical formula of the magnetotactic bacterium. By developing a stoichiometric equation characterizing the formation of a magnetotactic bacterial cell, coupled with rigorous experimental measurements and robust calculations, we report the elemental formula of M. gryphiswaldense cell as CH(2.06)O(0.13)N(0.28)Fe(1.74×10(-3)). Remarkably, we find that iron metabolism during growth of this magnetotactic bacterium is much more correlated individually with carbon and nitrogen, compared to carbon and nitrogen with each other, indicating that iron serves more as a nutrient during bacterial growth rather than just a mineral. Magnetotactic bacteria have not only invoked some interest in the field of astrobiology for the last two decades, but are also prokaryotes having the unique ability of synthesizing membrane bound intracellular organelles. Our findings on these unique prokaryotes are a strong addition to the limited repertoire, of elemental compositions of living cells, aimed at exploring the chemical logic of life.

  2. Dirac's monopole, quaternions, and the Zassenhaus formula

    Soloviev, Michael A

    2016-01-01

    Starting from the quaternionic quantization scheme proposed by Emch and Jadczyk for describing the motion of a quantum particle in the magnetic monopole field, we derive an algorithm for finding the differential representation of the star product generated by the quaternionic Weyl correspondence on phase-space functions. This procedure is illustrated by explicit calculation of the star product up to the second order in the Planck constant. Our main tools are an operator analog of the twisted convolution and the Zassenhaus formula for the products of exponentials of noncommuting operators.

  3. Variational formulas of higher order mean curvatures

    Xu, Ling

    2011-01-01

    In this paper, we establish the first variational formula and its Euler-Lagrange equation for the total $2p$-th mean curvature functional $\\mathcal {M}_{2p}$ of a submanifold $M^n$ in a general Riemannian manifold $N^{n+m}$ for $p=0,1,...,[\\frac{n}{2}]$. As an example, we prove that closed complex submanifolds in complex projective spaces are critical points of the functional $\\mathcal {M}_{2p}$, called relatively $2p$-minimal submanifolds, for all $p$. At last, we discuss the relations between relatively $2p$-minimal submanifolds and austere submanifolds in real space forms, as well as a special variational problem.

  5. THE CODIMENSION FORMULA ON AF-COSUBMODULES

    Let M1,M2 be submodules of analytic Hilbert module X on Ω( Cn) such that M1 M2and dimM1/M2 = k <∞.If M2 is an AF-cosubmodule,then the codimension dimM1/M2 of M2 in M1 equals the cardinality of zeros of M2 related to M1 by counting multiplicities.The codimension formula has some interesting applications.In particular,the author calculates out the dimension of Rudin quotient module,which is raised in [14].

  6. Local index formula and twisted spectral triples

    CERN Document Server

    Moscovici, Henri

    2009-01-01

    We prove a local index formula for a class of twisted spectral triples of type III modeled on the transverse geometry of conformal foliations with locally constant transverse conformal factor. Compared with the earlier proof of the untwisted case, the novel aspect resides in the fact that the twisted analogues of the JLO entire cocycle and of its retraction are no longer cocycles in their respective Connes bicomplexes. We show however that the passage to the infinite temperature limit, respectively the integration along the full temperature range against the Haar measure of the positive half-line, has the remarkable effect of curing in both cases the deviations from the cocycle identity.

  7. Perturbative Semiclassical Trace Formulae for Harmonic Oscillators

    DEFF Research Database (Denmark)

    Møller-Andersen, Jakob; Ögren, Magnus

    2015-01-01

    In this article we extend previous semiclassical studies by including more general perturbative potentials of the harmonic oscillator in arbitrary spatial dimensions. Our starting point is a radial harmonic potential with an arbitrary even monomial perturbation, which we use to study the resulting...... U(D) to O(D) symmetry breaking. We derive the gross structure of the semiclassical spectrum from periodic orbit theory, in the form of a perturbative (ħ → 0) trace formula. We then show how to apply the results to even-order polynomial potentials, possibly including mean-field terms. We have drawn...

  8. ON IMMERSION FORMULAS FOR SOLITON SURFACES

    Directory of Open Access Journals (Sweden)

    Alfred Michel Grundland

    2016-06-01

    Full Text Available This paper is devoted to a study of the connections between three different analytic descriptions for the immersion functions of 2D-surfaces corresponding to the following three types of symmetries: gauge symmetries of the linear spectral problem, conformal transformations in the spectral parameter and generalized symmetries of the associated integrable system. After a brief exposition of the theory of soliton surfaces and of the main tool used to study classical and generalized Lie symmetries, we derive the necessary and sufficient conditions under which the immersion formulas associated with these symmetries are linked by gauge transformations. We illustrate the theoretical results by examples involving the sigma model.

  10. Thermophysical Properties of Fluids and Fluid Mixtures

    Energy Technology Data Exchange (ETDEWEB)

    Sengers, Jan V.; Anisimov, Mikhail A.

    2004-05-03

    The major goal of the project was to study the effect of critical fluctuations on the thermophysical properties and phase behavior of fluids and fluid mixtures. Long-range fluctuations appear because of the presence of critical phase transitions. A global theory of critical fluctuations was developed and applied to represent thermodynamic properties and transport properties of molecular fluids and fluid mixtures. In the second phase of the project, the theory was extended to deal with critical fluctuations in complex fluids such as polymer solutions and electrolyte solutions. The theoretical predictions have been confirmed by computer simulations and by light-scattering experiments. Fluctuations in fluids in nonequilibrium states have also been investigated.

    The WZ production cross section is measured by the CMS experiment at the CERN LHC in proton-proton collision data samples corresponding to integrated luminosities of 4.9[Formula: see text] collected at [Formula: see text], and 19.6[Formula: see text] at [Formula: see text]. The measurements are performed using the fully-leptonic WZ decay modes with electrons and muons in the final state. The measured cross sections for [Formula: see text] are [Formula: see text] [Formula: see text] and [Formula: see text] [Formula: see text]. Differential cross sections with respect to the [Formula: see text] boson [Formula: see text], the leading jet [Formula: see text], and the number of jets are obtained using the [Formula: see text] data. The results are consistent with standard model predictions and constraints on anomalous triple gauge couplings are obtained.

    The objective of this study was to determine the thermal injury fluid resuscitation protocols at intensive care units (ICUs) in the United Kingdom and Ireland. A telephone questionnaire was designed to survey the fluid resuscitation protocols of ICUs at all hospitals with plastic/burn surgery departments in the British Isles in 2010. The feedback from the questionnaire was from the senior nurse in charge of the ICUs. 32/64 (50%) of these ICUs had provided care to burns patients. A 100% response from these 32 units was obtained. 71.4% commence fluid resuscitation at 15% total body surface area burn (TBSA), 21.4% at 20% TBSA and 7.1% at 10% TBSA in adults. The estimated resuscitation volume was most often calculated using the Parkland/Modified Parkland formula (87.5%) or the Muir and Barclay formula (12.5%). Interestingly, of the ICUs using formulae, two had recently moved from using the Muir and Barclay formula to Parkland formula and one had recently moved from using the Parkland formula to Muir and Barclay formula. Despite this, 37.5% of ICUs using a formula did not rigidly follow it exactly. The most commonly used resuscitation fluid was Ringer's lactate solution (46.9%) and Human Albumin Solution was used in 12.5%. No ICU used red cell concentrate as a first line fluid. 18.8% used a central line. 40.6% ICUs considered changing the IV solution during resuscitation. 78.1% ICUs consider urine output to be the most important factor in modifying resuscitation volumes. 59.4% ICUs calculate a maintenance fluid rate after completion of resuscitation. The endpoint for resuscitation was at 24 h in 46.9% ICUs and at 36 h in 9.4%. 5/32 (16%) felt their protocol gave too little and 6/32 (19%) felt their protocol gave too much. 59.3% ICUs gave oral/enteral fluids by naso-gastric or naso-jejenal tubes. 21.9% felt that oral/enteral resuscitation worked. Exactly half of the units believed that the formula that they used provided approximately the right amount of fluid, with 25

    Wu-Ling-San (WLS) formula has been proved to prevent calcium oxalate nephrolithiasis both in vitro and in vivo. This is the first prospective, randomized and placebo-controlled clinical trial of WLS in calcium oxalate nephrolithiasis prevention. All patients who enrolled were asked to drink enough fluid to urinate at least 2 L daily during the study period. A 24-hour urine collection was performed to establish the baseline levels of multiple urinary parameters before taking the medicine. The patients were randomized and divided into two groups. The medication group took 2 gm WLS formula three times daily for 1 month. The control group took 2 gm placebo three times daily for 1 month. A 24-hour urine collection was performed to evaluate multiple urinary and serum parameters from all patients during the study period. A total of 39 patients were enrolled and 28 patients completed the study. Fourteen patients were allocated to WLS group and 14 patients to placebo group. After treatment, the mean urine output level increased to 2796.4 ± 525.7 ml/day (percentage of change, 13.9 %) in the WLS formula group. With placebo therapy, the mean decreased slightly to 2521.4 ± 762.7ml/day (percentage of change, -5.7 %). The percentage of change was significantly different between the two groups (independent t-test, P=0.02). No patient complained of side effects, such as fatigue, dizziness, musculoskeletal symptoms, or gastrointestinal disturbance. WLS formula is a promising adjunct to surgical and medical management of kidney stones. Active therapy with WLS formula has a positive effect on diuresis without leading to electrolyte imbalance.

    Infant formulas are designed to be a substitute for breast milk. Since they are sole source of nutrition for growing and developing infants, they are highly regulated by the government. All ingredients in infant formulas must be considered "generally recognized as safe." Manufacturers are continually modifying their products to make them more like breast milk. Functional ingredients added to infant formula include long-chain polyunsaturated fatty acids, nucleotides, prebiotics, and probiotics. The most common breast milk substitutes are standard cow's milk-based term infant formulas, which include subcategories of organic and breast milk supplementation, and come in standard dilutions of 19 or 20 calories per ounce. In addition to standard cow's milk-based term infant formulas, there is a line of term infant formulas marketed for signs and symptoms of intolerance. These products include modifications in lactose content, partially hydrolyzed protein, added probiotics, or added rice starch. There are also specialized formulas for medical conditions such as prematurity, gastrointestinal disorders, allergy, disorders of fat metabolism, and renal insufficiency. Infants on specialty formulas should be monitored closely by medical professionals. Formulas come in ready-to-feed, liquid concentrate, and powder forms. Each offers advantages and disadvantages. Each step in the formula mixing process or each manipulation required for the feeding is another opportunity to introduce bacteria to the formula. There are guidelines for preparing formula in institutions. Standard dilution and mixing instructions are different for each formula, so individual recipes are needed. Caregivers should also be educated on proper hygiene when preparing formula at home.

    Dental caries are a major public health problem worldwide. The aim of this study was to compare the effects of children's follow-on instant powdered cow's milk formula, buffalo milk formula and a chicken-based formula on microhardness of bovine enamel with artificial caries-like lesions. Forty bovine teeth were each placed in acrylic blocks and the enamel surfaces were polished to create flat 5 x 5 millimeter surfaces. The teeth surfaces were then demineralized using 0.1M lactic acid (pH 4.5) to achieve an enamel microhardness of 35-65 Vickers Hardness Numbers (VHN). All specimens were then randomly allocated into one of 4 groups (n=10/group). For remineralization, each group was soaked in a different kind of milk formula for 2 hours at 37°C except group 1 which was a negative control (artificial saliva) group. Group 2 was soaked in Murrah™ buffalo milk formula (a positive control ), group 3 in S-26-Promil-Gold™ (cow's milk formula) and group 4 in a chicken-based formula (Siriraj Hospital, Mahidol University). The microhardness of the specimens was then measured again. Data were analyzed using a one-way ANOVA and paired t-test with a 95% confidence interval. After exposure to the formula, the mean VHN for each study group was significantly higher (paired t-test, p 0.05). In conclusion, S-26-Promil-Gold™ follow-on cow milk formula, Murrah™ buffalo milk formula and the chicken-based formula all increased bovine enamel microhardness after soaking for 2 hours.

    Hypothermia is a common complication in the hypovolemic patient. Warm intravenous fluids have proven valuable at preventing this complication during volume replacement. The microwave oven is considered an applicable alternative method for warming fluids but no protocol has been established. To evaluate the efficacy and affected variables of the microwave oven in warming crystalloid fluids and to determine the appropriate formula for calculating the warming duration. The important variables influencing the operation of the microwave oven include the difference between the crystalloid fluid and room temperature, the microwave oven's capability, variations in microwave irradiation, and fluid shaking. The appropriate formula for calculating warming duration is: Duration (sec) = Volume (cc) x 4.2j.g(-1).K(-1) x Raised temperature DeltaT (K) x 1.1 (Adjusted power) / Mivcwrowave power (W). The microwave oven is a safe and practical method for warming crystalloid fluids.

    Szabłowski, Paweł J

    2011-01-01

    We study some simple generalizations of the Poisson-Mehler summation formula (PM). In particular we exploit farther, the recently obtained equality {\\gamma}_{m,n}(x,y|t,q) = {\\gamma}_{0,0}(x,y|t,q)Q_{m,n}(x,y|t,q) where {\\gamma}_{m,n}(x,y|t,q) = \\Sigma_{i\\geq0}((t^{i})/([i]_{q}!))H_{i+n}(x|q)H_{m+i}(y|q), {H_{n}(x|q)}_{n\\geq-1} are the so called q-Hermite polynomials and {Q_{m,n}(x,y|t,q)}_{n,m\\geq0} are certain polynomials in x,y of order m+n being rational functions in t and q. We study properties of polynomials Q_{m,n}(x,y|t,q) expressing them with the help the so called Al-Salam--Chihara (ASC) polynomials and using them in expansion of the reciprocal of the right hand side of the Poisson-Mehler formula. We prove also some similar in nature equalities like e.g. the following \\Sigma_{i\\geq0}((t^{i})/([i]_{q}!))H_{n+i}(x|q) = H_{n}(x|t,q)\\Sigma_{i\\geq0}((t^{i})/([i]_{q}!))H_{i}(x|q), where H_{n}(x|t,q) is the so called big q-Hermite polynomial. We prove similar equalities involving big q-Hermite and ASC poly...

  19. From formulas to cirquents in computability logic

    CERN Document Server

    Japaridze, Giorgi

    2009-01-01

    Computability logic (CL) (see http://www.cis.upenn.edu/~giorgi/cl.html) is a recently introduced semantical platform and ambitious program for redeveloping logic as a formal theory of computability, as opposed to the formal theory of truth which logic has more traditionally been. Its expressions represent interactive computational tasks seen as games played by a machine against the environment, and "truth" is understood as existence of an algorithmic winning strategy. With logical operators standing for operations on games, the formalism of CL is open-ended, and has already undergone series of extensions. This article extends the expressive power of CL in a qualitatively new way, generalizing formulas (to which the earlier languages of CL were limited) to circuit-style structures termed cirquents. The latter, unlike formulas, are able to account for subgame/subtask sharing between different parts of the overall game/task. Among the many advantages offered by this ability is that it allows us to capture, refin...

  20. Multilinear Formulas and Skepticism of Quantum Computing

    CERN Document Server

    Aaronson, S

    2003-01-01

    Several researchers, including Leonid Levin, Gerard 't Hooft, and Stephen Wolfram, have argued that quantum mechanics will break down before the factoring of large numbers becomes possible. If this is true, then there should be a natural "Sure/Shor separator" -- that is, a set of quantum states that can account for all experiments performed to date, but not for Shor's factoring algorithm. We propose as a candidate the set of states expressible by a polynomial number of additions and tensor products. Using a recent lower bound on multilinear formula size due to Raz, we then show that states arising in quantum error-correction require n^{Omega(log n)} additions and tensor products even to approximate, which incidentally yields the first superpolynomial gap between general and multilinear formula size of functions. More broadly, we introduce a complexity classification of pure quantum states, and prove many basic facts about this classification. Our goal is to refine vague ideas about a breakdown of quantum mech...

  1. Surface diffuseness correction in global mass formula

    Wang, Ning; Wu, Xizhen; Meng, Jie

    2014-01-01

    By taking into account the surface diffuseness correction for unstable nuclei, the accuracy of the macroscopic-microscopic mass formula is further improved. The rms deviation with respect to essentially all the available mass data falls to 298 keV, crossing the 0.3 MeV accuracy threshold for the first time within the mean-field framework. Considering the surface effect of the symmetry potential which plays an important role in the evolution of the "neutron skin" toward the "neutron halo" of nuclei approaching the neutron drip line, we obtain an optimal value of the symmetry energy coefficient J=30.16 MeV. With an accuracy of 258 keV for all the available neutron separation energies and of 237 keV for the alpha-decay Q-values of super-heavy nuclei, the proposed mass formula is particularly important not only for the reliable description of the r-process of nucleosynthesis but also for the study of the synthesis of super-heavy nuclei.

    1982-11-01

    The Nutrient Surveillance Branch has been conducting a survey of infant formula products for Fiscal Year 1981. Each product has been carefully analyzed and the results compared to the label declaration and the minimum-maximum limits specified by the American Academy of Pediatrics' Committee on Nutrition (CON/AAP). Proximate and elemental analyses were made. Protein, fat, ash, and total solids (moisture) were determined by AOAC methods. Osmolality, density, and fatty acids (linoleic) were also determined. Carbohydrates were calculated by difference and caloric content was calculated by using the general Atwater factors. Elemental analysis for Ca, P, Mg, Fe, Zn, Cu, Mn, Na, and K were performed by induction coupled plasma absorption spectroscopy. Chloride was assayed by potentiometric titration with AgNO3. A summary of the findings from the infant formula survey have been compared with CON/AAP recommendations. In general, there were only a few exceptions where the label claims and the CON/AAP requirements were not met. However, in none of these cases was the difference considered to be of public health significance.

    We present results on transverse momentum ([Formula: see text]) and rapidity ([Formula: see text]) differential production cross sections, mean transverse momentum and mean transverse momentum square of inclusive [Formula: see text] and [Formula: see text] at forward rapidity ([Formula: see text]) as well as [Formula: see text]-to-[Formula: see text] cross section ratios. These quantities are measured in pp collisions at center of mass energies [Formula: see text] and 13 TeV with the ALICE detector. Both charmonium states are reconstructed in the dimuon decay channel, using the muon spectrometer. A comprehensive comparison to inclusive charmonium cross sections measured at [Formula: see text], 7 and 8 TeV is performed. A comparison to non-relativistic quantum chromodynamics and fixed-order next-to-leading logarithm calculations, which describe prompt and non-prompt charmonium production respectively, is also presented. A good description of the data is obtained over the full [Formula: see text] range, provided that both contributions are summed. In particular, it is found that for [Formula: see text] GeV/c the non-prompt contribution reaches up to 50% of the total charmonium yield.

  4. A statefinder luminosity distance formula in varying speed of light cosmology

    Balcerzak, Adam

    2014-01-01

    We derive a luminosity distance formula for the varying speed of light (VSL) theory which involves higher order characteristics of expansion such as jerk, snap and lerk which can test the impact of varying $c$ onto the evolution of the universe. We show that the effect of varying $c$ is possible to be isolated due to the relations connecting observational parameters already by measuring the second-order term in redshift $z$ unless there is a redundancy between the curvature and an exotic fluid of cosmic strings scaling the same way as the curvature.

    2017-02-01

    A direct entry and simple process for the synthesis of [Formula: see text]-spiroiminolactones present in a large number of natural products has been developed. In the first step, the synthesis of parabanic acid derivatives was commenced from the reaction of [Formula: see text]-disubstituted urea and thiourea with oxalyl chloride, then a three-component reaction was carried out with isocyanides, acetylenic esters, and [Formula: see text]-disubstituted parabanic acid derivatives. The method allows the construction of a variety of [Formula: see text]-spiroiminolactone structures in good to high yields starting from readily available precursors. It was found that in the case of [Formula: see text]-diphenyl thioparabanic acid, additional products of [Formula: see text]-dispiroiminolactones have been formed due to the higher electrophilicity of [Formula: see text]-dicarbonyl groups. The structures were fully established using spectroscopic analysis NMR, IR, and Mass spectrometry. The crystal structure of [Formula: see text]-dispiroiminolactone was confirmed from single-crystal X-ray diffraction study.

    destacan el involucramiento del equipo de soporte básico en la atención prehospitalaria e indican la necesidad de prevención de esos daños y de calificación de los trabajadores para la estructuración del trabajo basado en la interdisciplinaridad.OBJECTIVES: to identify types of occurrence registered by a pre-hospital care unit and to characterize occurrences from traffic accidents. METHODS: a descriptive cross-sectional study was used to analyze 6,430 pre-hospital calls from July to September, 2003. RESULTS: the occurrences were classified as trauma (35.2 %, or traffic accidents (57.9%. Most occurrences took place in the afternoon and were common in all days of the week. The basic pre-hospital care team, consisting of a licensed practical nurse or associate degree nurse and an ambulance driver, was the team that answered most emergency calls (84.5%. A professional nurse participated in only 11.2% of the occurrences, and great part of these occurrences (4.27% was answered by the advanced pre-hospital care team. A physician participated in only 8.3% of occurrences. CONCLUSION: the basic pre-hospital care team was involved in the majority of emergency calls. This suggests a need of new strategies for preventing victim's complications and better ways to qualify pre-hospital care team members for a quality interdisciplinary-based work.

  9. On Proto-Slavic Oath Formulas

    Directory of Open Access Journals (Sweden)

    Jasmina Grković-Major

    2012-08-01

    Full Text Available This paper deals with Slavic oath formulas containing the phrases ‘stand firm’ and ‘hold firm’, found mostly in peace treaties. The analysis carried out on the rich corpus of Old Serbian charters written in the vernacular and followed by a comparison with the data from Old Russian. The research is an attempt to reconstruct their possible Proto-Slavic structure, both linguistic and conceptual. After presenting the relevant data, the author reconstructs the following Proto-Slavic formulas: * stojati tvrьdo / krěpьko vь / na klętvě ( kъ komu ‘stand firm in / on the oath toward someone’, * drьžati tvrьdo / krěpьko klętvǫ ( kъ komu ‘hold firm the oath toward someone’. Both Serbian and Russian charters show lexical variations in the prepositional phrase and in the adverbial modifier of the formulas, which testify to their semantic compositionality. The etymology of their basic lexical constituents (* stojati, * drьžati, * tvrъdo, * krěpьko indicates that ‘immobility, firmness’ is their core meaning, * drьžati ‘make immobile > hold’ being just a transitive version of * stojati ‘be immobile > stand’. The concrete, physical concepts ‘stand’ and ‘hold’ were mapped into the target domain of the abstract ones (> ‘exist’ and ‘keep, have’. They represent the embodied experience and speak in favor of Embodied Realism. Indo-European parallels show that ‘stand’ and ‘hold’ belong to some of the basic Indo-European (although not just Indo-European conceptual metaphors, having a deep cultural motivation. These notions were so deeply rooted into the conceptual apparatus that they survived the change of cultural codes, becoming an integral part of the oath in Christian times. As time went by, they were secularized and reduced to phraseological units. They still exist today, even with the same lexical constituents as in the medieval charters, e.g. Serb. držati X ( reč, obećanje, veru, Russ

  12. Entropy Formulas For Dynamical Systems With Mistakes

    CERN Document Server

    Rousseau, Jerome; Zhao, Yun

    2010-01-01

    We study the recurrence to mistake dynamical balls, that is, dynamical balls that admit some errors and whose proportion of errors decrease tends to zero with the length of the dynamical ball. We prove, under mild assumptions, that the measure-theoretic entropy coincides with the exponential growth rate of return times to mistake dynamical balls and that minimal return times to mistake dynamical balls grow linearly with respect to its length.Moreover we obtain averaged recurrence formula for subshifts of finite type and suspension semiflows. Applications include $\\beta$-transformations, Axiom A flows and suspension semiflows of maps with a mild specification property. In particular we extend some results from [4, 9, 17] for mistake dynamical balls.

    Hanany, Amihay; Sperling, Marcus

    2017-02-01

    The monopole formula provides the Hilbert series of the Coulomb branch for a 3-dimensional N=4 gauge theory. Employing the concept of a fan defined by the matter content, and summing over the corresponding collection of monoids, allows the following: firstly, we provide explicit expressions for the Hilbert series for any gauge group. Secondly, we prove that the order of the pole at t = 1 and t → ∞ equals the complex or quaternionic dimension of the moduli space, respectively. Thirdly, we determine all bare and dressed BPS monopole operators that are sufficient to generate the entire chiral ring. As an application, we demonstrate the implementation of our approach to computer algebra programs and the applicability to higher rank gauge theories.

  14. Some applications of Rice formulas to waves

    CERN Document Server

    Azaïs, Jean-Marc; Wschebor, Mario

    2009-01-01

    We use Rice's formulas in order to compute the moments of some level functionals which are linked to problems in oceanography and optics. For instance, we consider the number of specular points in one or two dimensions, the number of twinkles, the distribution of normal angle of level curves and the number or the length of dislocations in random wavefronts. We compute expectations and in some cases, also second moments of such functionals. Moments of order greater than one are more involved, but one needs them whenever one wants to perform statistical inference on some parameters in the model or to test the model itself. In some case we are able to use these computations to obtain a Central Limit Theorem.

    We introduce and study probabilistic interpolations of various quantization methods. To do this, we develop a method for finding the expectations of unbounded random operators on a Hilbert space by averaging (with the help of Feynman formulae) the random one-parameter semigroups generated by these operators (the usual method for finding the expectations of bounded random operators is generally inapplicable to unbounded ones). Although the averaging of families of semigroups generates a function that need not possess the semigroup property, the Chernoff iterates of this function approximate a certain semigroup, whose generator is taken for the expectation of the original random operator. In the case of bounded random operators, this expectation coincides with the ordinary one.

    The quantification of the radial transport of gaseous species and solid particles is important to many applications in protoplanetary disk evolution. An especially important example is determining the location of the water snow lines in a disk, which requires computing the rates of outward radial diffusion of water vapor and the inward radial drift of icy particles; however, the application is generalized to evaporation fronts of all volatiles. We review the relevant formulas using a uniform formalism. This uniform treatment is necessary because the literature currently contains at least six mutually exclusive treatments of radial diffusion of gas, only one of which is correct. We derive the radial diffusion equations from first principles using Fick's law. For completeness, we also present the equations for radial transport of particles. These equations may be applied to studies of diffusion of gases and particles in protoplanetary and other accretion disks.

    Inhibitors of mTOR, including clinically available rapalogs such as rapamycin (Sirolimus) and Everolimus, are gerosuppressants, which suppress cellular senescence. Rapamycin slows aging and extends life span in a variety of species from worm to mammals. Rapalogs can prevent age-related diseases, including cancer, atherosclerosis, obesity, neurodegeneration and retinopathy and potentially rejuvenate stem cells, immunity and metabolism. Here, I further suggest how rapamycin can be combined with metformin, inhibitors of angiotensin II signaling (Losartan, Lisinopril), statins (simvastatin, atorvastatin), propranolol, aspirin and a PDE5 inhibitor. Rational combinations of these drugs with physical exercise and an anti-aging diet (Koschei formula) can maximize their anti-aging effects and decrease side effects.

    Full Text Available New empirical formulas of the transmission coefficient for permeable breakwaters were suggested based on available experimental data regarding the low-crest structure (LCS, including the permeable rubble mound breakwater and pile-type breakwater. The rationality of the present formulas was verified by their comparison with existing empirical and analytical formulas. Numerical flume results were obtained by solving the modified Boussinessq-type wave equations (MBEs, and a new expression relating the friction coefficient to the relative submerged depth was also derived. Comparative analysis shows that the results of the present formulas agree with the numerical flume results as well as available experimental data, and the present formulas are superior to the existing empirical and analytical expressions in estimating the transmission coefficient. The present formulas can provide references for estimation of the transmission coefficient in engineering practice.
