First application of the marine differential electric dipole for groundwater investigations: A case study from Bat Yam, Israel
Authors: Haroon Amir , Lippert Klaus , Mogilatov Vladimir , Tezkan Bülent 
Published: December 2017

The marine differential electric dipole (DED) is applied for the first time to study a subseafloor groundwater body in the coastal region of Bat Yam, Israel. Previous marine long-offset transient electromagnetic applications detected this freshwater body underneath the Mediterranean seafloor. We have applied the novel DED method for the first time in the marine environment to further investigate this natural phenomenon. The main objectives are to locate the freshwater-seawater interface at the western aquifer edge and to identify the mechanism controlling this freshwater occurrence beneath the seafloor. The acquired step-on signals allow one to detect the freshwater body in the vicinity of the Israeli coastline at a depth of approximately 70 m beneath the seafloor. However, aquifer thickness is only poorly determined and may vary between 40 and 100 m. A lateral resistivity contrast is observable between adjacent 1D inversion models and also apparent in data profile curves that constrain the seaward extent of the detected resistive body to a distance of less than 4 km from the coastline. A subsequent 2.5D forward-modeling study aims to find a subseafloor resistivity distribution that adequately explains all measured DED data simultaneously. The results further constrain the lateral extent of the resistive aquifer to approximately 3.6–3.7 km from the Israeli coast. Furthermore, the data indicate that the aquifer system may be susceptible to seawater intrusion, as a superior data fit is achieved if a brackish water zone of approximately [Formula: see text] with a lateral extent of less than 300 m is located at the head of the freshwater body.

Introduction: Optimal scheduling and calendar management in an outpatient chemotherapy unit is a complex process that is driven by a need to focus on safety while accommodating a high degree of variability. Primary constraints are infusion times, staffing resources, chair availability, and unit hours. Methods: We undertook a process to analyze our existing management models across multiple practice settings in our health care system, then developed a model to optimize safety and efficiency. The model was tested in one of the community chemotherapy units. We assessed staffing violations as measured by nurse-to-patient ratios throughout the workday and at key points during treatment. Staffing violations were tracked before and after the implementation of the new model. Results: The new model reduced staffing violations by nearly 50% and required fewer chairs to treat the same number of patients for the selected clinic day. Actual implementation results indicated that the new model leveled the distribution of patients across the workday with an 18% reduction in maximum chair utilization and a 27% reduction in staffing violations. Subsequently, a positive impact on peak pharmacy workload reduced delays by as much as 35 minutes. Nursing staff satisfaction with the new model was positive. Conclusion: We conclude that the proposed optimization approach with regard to nursing resource assignment and workload balance throughout a day effectively improves patient service quality and staff satisfaction.

Purpose: Despite growing interest in bundled payments to reduce the costs of care, this payment method remains largely untested in cancer. This 3-year pilot tested the feasibility of a 1-year bundled payment for the multidisciplinary treatment of head and neck cancers. Methods: Four prospective treatment-based bundles were developed for patients with selected head and neck cancers. These risk-adjusted bundles covered 1 year of care that began with primary cancer treatment. Manual processes were developed for patient identification, enrollment, billing, and payment. Patients were prospectively identified and enrolled, and bundled payments were made at treatment start. Operational metrics tracked incremental effort for pilot processes and average payment cycle time compared with fee-for-service (FFS) payments. Results: This pilot confirmed the feasibility of a 1-year prospective bundled payment for head and neck cancers. Between November 2014 and October 2016, 88 patients were enrolled successfully with prospective bundled payments. Through September 2017, 94% of patients completed the pilot with 6% still enrolled. Manual pilot processes required more effort than anticipated; claims processing was the most time-consuming activity. The production of a bundle bill took an additional 15 minutes versus FFS billing. The average payment cycle time was 37 days (range, 15 to 141 days) compared with a 15-day average under FFS. Conclusion: Prospective bundled payments were successfully implemented in this pilot. Additional pilots should study this payment method in higher-volume cancers. Robust systems are needed to automate patient identification, enrollment, billing, and payment along with policies that reduce administrative burden and allow for the introduction of novel cancer therapies.
Hyperpolarized gas MRI in pulmonology
Authors: Kern Agilo Luitger , Vogel-Claussen Jens 
Published: December 2017

Lung diseases have a high prevalence amongst the world population and their early diagnosis has been pointed out to be key for successful treatment. However, there is still a lack of non-invasive examination methods with sensitivity to early, local deterioration of lung function. Proton-based lung MRI is particularly challenging due to short T 2 * times and low proton density within the lung tissue. Hyperpolarized gas MRI is aan emerging technology providing a richness of methodologies which overcome the aforementioned problems. Unlike proton-based MRI, lung MRI of hyperpolarized gases may rely on imaging of spins in the lung’s gas spaces or inside the lung tissue and thereby add substantial value and diagnostic potential to lung MRI. This review article gives an introduction to the MR physics of hyperpolarized media and presents the current state of hyperpolarized gas MRI of 3Headvasd and 129Xe in pulmonology. Key applications, ranging from static and dynamic ventilation imaging as well as oxygen-pressure mapping to 129Xe dissolved-phase imaging and spectroscopy are presented. Hyperpolarized gas MRI is compared to alternative examination methods based on MRI and future directions of hyperpolarized gas MRI are discussed.
Effects of contrast administration on cardiac MRI volumetric, flow and pulse wave velocity quantification using manual and software-based analysis
Authors: Fathi Amir , Weir-McCall Jonathan R , Struthers Allan D , Lipworth Brian J , Houston Graeme 
Published: December 2017

Objective:
The aim of the current study was to determine the effects of gadolinium contrast agent on right (RV) and left ventricular (LV) volumetric, aortic flow and pulse wave velocity (PWV) quantification using manual, semi-automatic and fully automatic analysis techniques.

Methods:
61 participants free from known cardiovascular disease were recruited. Cardiac MR was performed on a 3 T scanner. A balanced steady-state free precession stack was acquired of the ventricles with phase contrast imaging of the aorta performed pre- and post-administration of 10 ml 0.5 mmol ml−1 gadoterate meglumine. The images were analysed manually, and using a semi-automated and a fully automated technique.

Results:
54 completed the study. Gadolinium-based contrast administration significantly increase the signal-to-noise ratio (pre: 830 ± 398 vs post: 1028 ± 540, p = 0.003) with no significant change in contrast-to-noise ratio (pre: 583 ± 302 vs post: 559 ± 346, p = 0.54). On LV analysis, post-contrast analysis yielded significantly higher end systolic volume (54 ± 20 vs 57 ± 18 ml, p = 0.04), and lower ejection fraction (59 ± 9 vs 57 ± 8%, p = 0.023). On RV analysis, gadolinium contrast resulted in no significant differences. Similar results were seen using the semi-automated and fully-automated techniques but with a larger magnitude of difference. Conversely, using both manual and software analysis aortic flow and PWV quantification proved robust to the effects of contrast agent producing only small non-significant differences.

Conclusion:
Gadolinium contrast administration significantly alters LV endocardial contour detection with this effect amplified when using semi-automated analysis techniques. In comparison, RV and PWV analysis is robust to these effects.

Advances in knowledge:
Contrast administration alters LV quantification but not flow analysis. However, these differences are small.
A high 18F-FDOPA uptake is associated with a slow growth rate in diffuse Grade II–III gliomas
Authors: Isal Sibel , Gauchotte Guillaume , Rech Fabien , Blonski Marie , Planel Sophie , Chawki Mohammad B , Karcher Gilles , Marie Pierre-Yves , Taillandier Luc , Verger Antoine 
Published: December 2017

Objective:
In diffuse Grade II–III gliomas, a high3,4-dihydroxy-6-(18F)-fluoro-L-phenylalanine (18F-FDOPA) positron emission tomography (PET) uptake, with a standardized uptake value (SUVmax)/contralateral brain tissue ratio greater than 1.8, was previously found to be consistently associated with the presence of an isocitrate dehydrogenase (IDH) mutation, whereas this mutation is typically associated with a better prognosis. This pilot study was aimed to ascertain the prognostic value of this high 18F-FDOPA uptake in diffuse Grade II–III gliomas with regard to the velocity of diameter expansion (VDE), which represents an established landmark of better prognosis when below 4 mm per year.

Methods:
20 patients (42 ± 10 years, 10 female) with newly-diagnosed diffuse Grade II–III gliomas (17 with IDH mutation) were retrospectively included. All had a 18F-FDOPA PET, quantified with SUVmax ratio, along with a serial MRI enabling VDE determination.

Results:
SUVmax ratio was above 1.8 in 5 patients (25%) all of whom had a VDE &lt;4 mm/year (100%) and IDH mutation (100%). Moreover, a SUVmax ratio above 1.8 was associated with higher rates of VDE &lt;4 mm/year in the overall population (45 vs 0%, p = 0.04) and also in the subgroup of patients with IDH mutation (45 vs 0%, p = 0.10).

Conclusion:
This pilot study shows that in diffuse Grade II–III gliomas, a high 18F-FDOPA uptake would be predictive of low tumour growth, with a different prognostic significance than IDH mutation.

Advances in knowledge:
18F-FDOPA PET in a single session imaging could have prognostic value in initial diagnosis of diffuse Grade II–III gliomas.
The Many Gifts of Status: How Attending to Audience Reactions Drives the Use of Status
Authors: Sharkey Amanda J. , Kovács Balázs 
Published: December 2017

The majority of extant studies involving status argue that status enters into choice and evaluation because people personally believe that status serves as a signal of quality. However, this mechanism seems less plausible in cases when consensus on the meaning of quality is lacking. To understand how and why status often nonetheless enters into evaluation in those cases, this paper contributes to a growing body of work that proposes that individuals and organizations are particularly likely to base their choices and evaluations on status when they are concerned with the reactions of others. We provide an empirical test of this argument by analyzing how the sales gap between prizewinning books and their shortlisted-only peers (as well as a second similar-content control group) changes during the December holidays, when the purchase of books as gifts increases relative to purchases for one’s own personal use. Results show that the sales gap widens with the increased orientation toward gift giving, consistent with our theoretical arguments about how attending to audience reactions drives the use of status. Analyses of two online experiments allow for further clarification of the mechanism behind our findings.This paper was accepted by Ray Reagans, organizations.

Published: December 2017

Managing perishable inventory systems with positive lead times and finite ordering capacities is important but notoriously difficult in both theory and computation. The optimal control policy is extremely complicated, and no effective heuristic policy has been proposed in the literature. In this paper, we develop an easy-to-compute approximation algorithm for this class of problems and prove that it admits a theoretical worst-case performance guarantee under independent and many commonly used positively correlated demand processes. Our worst-case analysis departs significantly from those in the previous studies, requiring several novel ideas. In particular, we introduce a transient unit-matching rule to dynamically match the supply and demand units, and the notion of associated demand processes that provides the right future demand information to establish the desired results. Our numerical study demonstrates the effectiveness of the proposed algorithm. This paper was accepted by Yinyu Ye, optimization.
Looking for blind spots in somatics’ evolving pathways
Authors: Fortin Sylvie 
Published: December 2017

Abstract
The field of somatics has expanded tremendously since Hanna introduced the term in the 1970’s. This reflective paper has evolved from my experience as a practitioner and theorist of somatics over the last 30 years. As such I will address the broadness of the field of somatics by looking at five pathways undertaken by somatic practitioners: social, ecological, spiritual, health and well-being and education. Possibilities and constraints within each of these pathways are critically examined, from an intimate, embodied and socio-political perspective, in order to bring awareness to possible blind spots associated with each pathway. In doing so, I attempt to counter overzealous stances towards somatics while at the same time recognizing and valuing its tremendous potential to generate individual and collective agency.
Eje 2. El cine argentino y español: épocas, aportes y debates: Entre el Peronismo, el tercer mundo y los usos sociales del cine. Notas sobre el Instituto de Cinematografía de la UNL en 1973
Authors: Mestman Mariano 
Published: December 2017

El artículo se focaliza en el Instituto de Cinematografía (IC) de la Universidad Nacional del Litoral (UNL), Argentina, en torno a 1973–1974, no tanto en lo referido a la organización institucional e interna sino a cuatro cuestiones que lo singularizan: la asunción de nuevas autoridades alineadas con el programa de Reconstrucción Nacional del Peronismo en el gobierno; la recuperación del proyecto inicial del Instituto, el del período en que Fernando Birri lo dirigió (1956–1962); los vínculos con imaginarios y experiencias nacionales e internacionales, de América Latina y del llamado Tercer Mundo; el uso social del cine con fines educativos y políticos. El texto parte de la bibliografía existente sobre los conflictos y polémicas al interior del IC: con el director interventor durante 1969–1970, así como entre grupos de afinidad en torno al documental social, por un lado, y a la indagación de lenguajes y estéticas contemporáneas, por otro. Desde allí se propone una lectura del proyecto de 1973 en relación con esos y otros sucesos de los años previos y con la historia más larga del Instituto. Se anexan tres documentos internos de la gestión del IC de 1973–1974, hasta ahora inéditos.
Eje 4. Análisis de textos cinematográficos: en tanto representación de nuevas formas de sociabilidad y como acción social reflexiva: Nihilismo sociocultural y pérdida del mundo en Extension du domaine de la lutte (1999) de Philippe Harel y Michel Houellebecq
Authors: Ortega Joaquín Esteban 
Published: December 2017

El peculiar nihilismo que atraviesa la obra literaria de Michel Houellebecq resulta ser no únicamente la posibilidad de un reflejo estético de nuestra vida social sino también una acción social reflexiva en sí misma susceptible de ser tenida en cuenta como conocimiento social. El presente artículo toma como referencia la adaptación cinematográfica que Philippe Harel realizó en 1999 sobre la novela del escritor francés titulada Extension du domaine de la lutte (Ampliación del campo de batalla) para constatar que nuestra época está favoreciendo la hibridación de los discursos y para cuestionar la posibilidad de vivir más allá de esa última ilusión que parece ser la de vivir sin ilusiones.
Detection of Shigella dysenteriae Type 1 in Milk by PCR
Authors: Gupta Pallavi , Dhaked Ram Kumar 
Published: December 2017

<p>Shigellosis is severest form of bacillary dysentery, a disease limited to humans and certain other primates. Conventional microbiological techniques used for the isolation and biochemical identification of microbes are time-consuming as well as labour intensive. Due to the fastidious nature of <em>Shigella</em> and the lengthy culture time, a rapid and sensitive system for the detection of bacteria is highly desirable. Nucleic acid-based techniques have enormous potential in the detection of biological weapons because of their specificity, sensitivity, and the speed with which results can be obtained. The application of polymerase chain reaction in sensitive detection of bacterial pathogens in direct food samples is largely affected by the quality of the template DNA. To overcome the shortcomings of conventional methods, we have defined simple method of sample preparation that facilitates PCR based detection of <em>Shigella dysenteriae</em> in milk. In present study, gene specific primers were designed to detect <em>stxA</em> gene.<em> </em>The genomic DNA extraction from the spiked milk was carried out by proteinase K, lysozyme, chloroform-isoamyl alcohol and heat treatments. The optimized extraction of DNA by addition of chloroform-isoamyl alcohol proved to be the most satisfactory amongst all, with limit of detection of 2.0 x 10<sup>3 </sup>cfu/ reaction and was completed in 4h.</p><p> </p>
Development of Scale and Rotation Invariant Neural Network based Technique for Detection of Dielectric Contrast Concealed Targets with Millimeter Wave System
Authors: Kumar Bambam , Sharma Prabhat , Singh Dharmendra 
Published: December 2017

<p class="p1">The detection of concealed targets beneath a person’s clothing from standoff distance is an important task for protection and the security of a person in a crowded place like shopping malls, airports and playground stadium, etc. The detection capability of the concealed weapon depends on a lot of factors likes, a collection of back scattered data, dielectric property and a thickness of covering cloths, the hidden object, standoff distance and the probability of false alarm owing to objectionable substances. Though active millimeter wave systems have used to detect weapons under cloths, but still more attention is required to detect the target likes a gun, knife, and matchbox. To observe such problems, active V-band (59 GHz- 61 GHz) MMW radar with the help of artificial neural network (ANN) has been demonstrated for non-metallic as well as metallic concealed target detection. To validate ANN, the signature of predefined targets is matched with the signature of validated data with the help of the correlation coefficient. The proposed technique has good capability to distinguish concealed targets under various cloths.<span class="Apple-converted-space"> </span></p>

Authors: Kwaśniewski Dariusz , Juliszewski Tadeusz , Walczyk Józef , Tylek Paweł , Adamczyk Florian , Szczepaniak Jan 
Published: December 2017

Abstract
The objective of the paper was to determine fuel consumption on elimination of the energy willow plantation with current mechanical methods with the use of the machine research model. The paper covers investigations of four machine units. The lowest fuel consumption (142.6 l∙ha−1) with the use of Meri Crusher MJS-2.0) did not ensure effectiveness of operation of this unit. Efficiency of elimination of the plantation in this case is only 36.4%. On the other hand, the highest consumption of diesel oil (776.4 l∙ha−1) was reported for FAO FAR model FV 4088, and the effectiveness of elimination was not satisfactory and it was 57.0%. The highest effectiveness of elimination of the plantation was reported for the model of a new machine. Fuel consumption in this case was 535.7 l∙ha−1 and the willow plantation elimination effectiveness was the highest and it amounted to 94.8%.

Modification of a recuperator construction with CFD methods
Authors: Ludwig Wojciech , Zając Daniel 
Published: December 2017

Abstract
The purpose of the work was initial modification of the construction of a commercially produced heat exchanger – recuperator with CFD (computational fluid dynamics) methods, based on designs and process parameters which were provided. Uniformity of gas distribution in the space between the tubes of the apparatus as well as the pressure drop in it were taken as modification criteria. Uniformity of the gas velocity field between the tubes of the heat exchanger should cause equalization of the local individual heat transfer coefficient values and temperature value. Changes of the apparatus construction which do not worsen work conditions of the equipment, but cause savings of constructional materials (elimination or shortening some parts of the apparatus) were taken into consideration.
