Published: April 2020

Ex-situ culture studies of five selected aquatic macrophytes, namely Nymphaea nouchali Burm. f., Enhydra fluctuans Lour., Ipomoea aquatica Forsk., Hygroryza aristata (Retz.) Nees ex Wight & Arn. and Limnocharis flava (L.) Buch. were carried out. Comparing the biochemical composition of the above mentioned five aquatic macrophytes, on an average, Enhydra fluctuans was found to contain highest amounts of proteins (18.20%) and Ipomoea aquatica contains highest amounts of carbohydrate (58.60%). Lowest amounts of proteins (14.35%) were recorded in Hygroryza aristata and Limnocharis flava. On the other hand lowest amounts of carbohydrates were obtained in Nymphaea nouchali. Ipomoea aquatica contained highest amounts of energy (321.23 kcal) and lowest amount was observed in Limnocharis flava. The five aquatic plants were low in fiber, fat and also in ash. Among all the five aquatic macrophytes, highest values of calcium and phosphorus were found to be present in Limnocharis flava and iron was highest in Nymphaea nouchali. Lowest values of calcium and phosphorus were present in Ipomoea aquatica and lowest amount of iron was present in Limnochris flava. The present study demonstrated that, these five aquatic macrophytes are the important sources of carbohydrate, protein and minerals, which are suitable for incorporation in human diet and feed also.

Authors: Hossain Khandaker Tanvir , Rahman Md Hafizur 
Published: April 2020

In Southkhali Union of Bagerhat district in Bangladesh about 47% of the total population is living beyond the service area of cyclone shelters (CS) not only for the carrying capacity of CS but also for the accessibility. Location-allocation tool of Network Analyst tool in ArcGIS determined the service area of each CS in the study area based on its shelter capacity and accessibility. People residing outside the service area of cyclone shelter are highly vulnerable due to low elevation of land and poor housing structure. The location-allocation tool of Network Analyst provided the proper evacuation plan that would identify the shelter location for each household or cluster of population and the evacuation route also. It would also help to find the proper location to build new shelters for unserved community.

Published: April 2020

BackgroundThe National Early Warning Score (NEWS) was introduced to standardise early warning scores (EWS) in England. It has been recommended that NEWS should be used in pre-hospital care but there is no published evidence that this improves outcomes. In 2015, the West of England Academic Health Science Network region standardised to NEWS across all healthcare settings. Calculation of NEWS was recommended for acutely unwell patients at referral into secondary care.AimTo evaluate whether implementation of NEWS across a healthcare system affects outcomes, specifically addressing the effect on mortality in patients with suspicion of sepsis (SOS).Design and settingA quality improvement project undertaken across the West of England from March 2015 to March 2019, with the aim of standardising to NEWS in secondary care and introducing NEWS into community and primary care.MethodData from the national dashboard for SOS for the West of England were examined over time and compared to the rest of England. Quality improvement methodology and statistical process control charts were used to measure improvement.ResultsThere was a reduction in mortality in the SOS cohort in the West of England, which was not seen in the rest of England over the time period of the project. Admissions did not increase. By March 2019, the West of England had the lowest mortality in the SOS cohort in England.ConclusionTo the authors’ knowledge, this is the first study demonstrating that use of NEWS in pre-hospital care is associated with improved outcomes in patients with SOS.

Для оценки направления на морской объект рассмотрено формирование пространственно-временногосигнала в приемной эквидистантной линейной антенной решетке в условиях плоского волнового фронта поляакустического давления, создаваемого сложным широкополосным сигналом. Модель формирования спектра информационного сигнала на выходе отдельного гидрофона антенной решетки представлена векторно-матричным уравнением в аддитивной смеси с шумом гидроакустического канала. Для оценивания такого сигнала применены методы линейного оценивания в спектральной области, позволяющие получить несмещенныеоценки с минимальной дисперсией. Найдена матрица весовых коэффициентов, с помощью которой шумовыекомпоненты отдельного гидрофона (приемного канала) приводятся к белому шуму с минимальной дисперсией.При суммировании спектров гидрофонов антенной решетки пространственно-временной сигнал на ее выходе определен с помощью оценок отдельных информационных сигналов гидрофонов и их остаточного шума сразной дисперсией. Минимальное значение дисперсии выходного шума антенной решетки получено на основании ковариационной матрицы остаточного шума. Предлагаемый оптимальный метод оценки направленияприхода сигнала от морского объекта на антенную решетку позволяет отказаться от избыточного числа еелиний задержки при одновременном значительном уменьшении влияния шума гидроакустического канала.The paper considers the estimation of the direction tothe marine objects by dealing with the formation of a spacetimesignal on the receiving equidistant linear antenna arrayin conditions of the flat wavefront of the acoustic pressurefield generated by a complex broadband signal. The modelof spectrum shaping of the information signal at the outputof a separate hydrophone of the antenna array is derived bythe vector-matrix equation in the additive mix with the noiseof the underwater acoustic channel. The estimation of sucha signal was performed by methods of linear evaluation inthe spectral domain, allowing to get unbiased estimates withthe least dispersion. The noise components of each separatehydrophone (receiving channel) are reduced to white noisewith minimal dispersion using the calculated weightingmatrix. The resulting space-time signal at the output of theantenna array obtained by the summing spectrums of all ofthe hydrophones can be determined by the estimation of theseparate information signals of each array element and itsresidual noise with different variance. The minimal value ofthe noise variance at antenna array output was obtained basedon the covariance matrix of the residual noise. The proposedoptimal method of the estimation of angle-of-arrival of thesignal from the remote marine object on the antenna arrayallows substantially decreasing both the number of its delaylines and the influence of the underwater acoustic channelnoise.

Abstract
How magnetic reconnection drives Mercury’s magnetospheric dynamics under extreme solar wind conditions is not well understood. Here we report MESSENGER observations of an active reconnection event in Mercury’s magnetotail driven by an interplanetary coronal mass ejection on 2011 November 23. The primary Hall magnetic field, sequential passage of X-lines with Hall field perturbations, and flux ropes (FRs) provide unambiguous evidence of multiple X-line reconnection in an unstable ion diffusion region. In addition, large FRs consisting of multiple successive small-scale FRs are ejected tailward at quasi-periodic intervals of ∼1 minute, which is comparable to the Dungey cycle time. We propose that these large FRs are generated by the interaction and coalescence of multiple ion-scale FRs. This is distinct from the commonly accepted Earth-like substorm process where plasmoids are created by widely separated X-lines in the magnetotail. These observations suggest that during extreme solar wind conditions multiple X-line reconnection may dominate the tail reconnection process and control the global dynamics of Mercury’s magnetosphere.
L’identité en face à face
Authors: Fhima Catherine 
Published: April 2020

L’article interroge l’identité à partir de l’étude du cas de l’écrivain Max Jacob et d’une configuration d’écrivains, juifs et français, entre 1890 et 1930. Conduite par l’idée que le concept d’« identité » ne gagne une valeur heuristique dans les sciences humaines et sociales qu’à la condition majeure d’être confronté à celui d’« altérité », la réflexion se fonde sur une méthode inductive permettant de dégager des principes d’analyse : l’identité ne peut être référée que par rapport à un processus historique et à un contexte spécifique évitant tout jugement classificatoire préétabli ; l’identité provient et procure du « trouble » ; elle est le produit d’interactions entre moi et tu et nous, vous et eux ; ce faisant, à la confluence des rapports entre individualités et modes d’être collectifs, elle est principe d’action. Ainsi, dans le cas d’écrivains, l’identité entraîne-t-elle un mode d’écrire soumis à une obligation de novation et au désir de marquer leur place en faisant œuvre singulière.

Authors: Doering Lynn V. , Moser Debra K. , Lemankiewicz Walter , Luper Cristina , Khan Steven 
Published: April 2020

• Background Effects of postoperative depression on recovery from coronary artery bypass grafting have not been widely studied.
• Objectives To evaluate emotional and physical recovery after bypass surgery and investigate associations between depressive symptoms and infections and impaired wound healing in patients with high and low levels of depressive symptoms.
• Methods A nonrandomized, comparative, longitudinal design was used to study 72 bypass surgery patients without serious noncardiac comorbidities who were available for follow-up after discharge. Patients completed questionnaires to assess depressive symptoms, emotional recovery, and physical recovery within 48 hours after extubation, at discharge from the hospital, and 6 weeks later and performed 6-minute walk tests at the last 2 times. Infections and impaired wound healing (as indicated by positive cultures, antibiotic treatment, or extra treatments, such as debridements or incisions and drainage) were identified by chart audit.
• Results At discharge, patients with higher depressive symptom scores (indicating more symptoms) reported poorer emotional recovery (P &lt; .001) and poorer physical recovery (P = .007) and achieved shorter walking distances (P&lt;.001) than did patients with lower scores (indicating fewer symptoms). Six weeks after discharge, emotional and physical recovery remained lower in patients with more depressive symptoms (P &lt; .001). Infections and impaired wound healing were more common among patients with higher depressive symptom scores (46%) than among patients with lower scores (19%, P=.03).
• Conclusions After bypass surgery, depressive symptoms are associated with infections, impaired wound healing, and poor emotional and physical recovery.
Improving Oral Care in Patients Receiving Mechanical Ventilation
Authors: Cutler Constance J. , Davis Nancy 
Published: April 2020

• Background Comprehensive oral care is an evidence-based prevention strategy to reduce the risk of ventilator-associated pneumonia in patients receiving mechanical ventilation. Until recently, no comprehensive guidelines or standards existed to define necessary tasks, methods, and frequency of oral care to provide patients with optimal results.• Objectives To observe current practice of, define best practice for, and measure compliance with standardized comprehensive oral care.• Methods This observational study was part of a larger research study performed at 5 acute care hospitals. Time blocks of 4 hours were randomized over 8 intensive care units and the 7 days of the week. Baseline data were collected before implementation of multifaceted education on an oral-cleansing protocol; interventional data were collected afterward.• Results Oral care practices were observed for 253 patients. During the baseline period, oral cleansing was primarily via suction swabs. Toothbrushing and moisturizing of the oral tissues were not observed. Only 32% of the patients had suctioning to manage oral secretions. During the interventional period, 33% of patients had their teeth brushed, 65% had swab cleansing, and 63% had a moisturizer applied to the oral mucosal tissues. A total of 61% had management of oral secretions; 38% had oropharyngeal suctioning via a special catheter.• Conclusions Implementation of an evidence-based oral cleansing protocol improved the care of patients receiving mechanical ventilation. Multifaceted education and implementation strategies motivated staff to increase oral care practices.

Published: April 2020

• Background Accreditation standards for certification programs require use of a testing mechanism that is job-related and based on the knowledge and skills needed to function in the discipline.• Objectives To describe critical care advanced practice by revising descriptors to encompass the work of both acute care nurse practitioners and clinical nurse specialists and to explore differences in the practice of clinical nurse specialists and acute care nurse practitioners.• Methods A national task force of subject matter experts was appointed to create a comprehensive delineation of the work of critical care nurses. A survey was designed to collect validation data on 65 advanced practice activities, organized by the 8 nurse competencies of the American Association of Critical-Care Nurses Synergy Model for Patient Care, and an experience inventory. Activities were rated on how critical they were to optimizing patients’ outcomes, how often they were performed, and toward which sphere of influence they were directed. How much time nurses devoted to specific care problems was analyzed. Frequency ratings were compared between clinical nurse specialists and acute care nurse practitioners.• Results Both groups of nurses encountered all items on the experience inventory. Clinical nurse specialists were more experienced than acute care nurse practitioners. The largest difference was that clinical nurse specialists rated as more critical activities involving clinical judgment and clinical inquiry whereas acute care nurse practitioners focused primarily on clinical judgment.• Conclusions Certification initiatives should reflect differences between clinical nurse specialists and acute care nurse practitioners.
Effect of a Specialized Pediatric Institutional Setting on Organ Recovery From Potential Donors

Published: April 2020

• Background The relationship between accessibility to the full range of subspecialty care available at freestanding pediatric hospitals and organ donor management and recovery rates has not been studied.
• Objective To examine current rates of recovery of organs from children for transplantation at free-standing pediatric hospitals versus all other hospitals.
• Methods Data from the hospitals served by Mid-America Transplant Services from January 2000 to July 2003 were reviewed. Organ recovery rates from freestanding children’s hospitals were compared with the rates from other types of institutions. Patients were included if their organs were considered medically suitable at the time of referral for donation.
• ResultsOverall, 66% (210/318) of the potential organs were recovered. The type of institution in which the potential donor was managed did not influence the proportion of organs recovered: 67% (96/144) at freestanding children’s hospitals versus 66% (114/174) at all other hospitals. A greater proportion of livers were recovered at other donor institutions than at children’s hospitals (100% vs 85%, P≤.01).
• Conclusion The organ recovery rate from potential pediatric donors is low. In general, this rate does not appear to be affected by the type of managing pediatric institution except for liver recovery, which favors institutions that are not freestanding children’s hospitals. The low rate of recovery suggests that although suitable donors are identified, appropriate referrals are made, and families provide consent for donation, major obstacles remain to the successful recovery of organs.
