Abstract
Objective To evaluate whether the use of intraoperative ultrasound leads to more conservative surgeries for benign ovarian tumors.
Methods Women who underwent surgery between 2007 and 2017 for benign ovarian tumors were retrospectively analyzed. The women were classified into two groups: those who underwent intraoperative ultrasound (group A) and those who did not (group B). In group A, minimally-invasive surgery was performed for most patients (a specific laparoscopic ultrasound probe was used), and four patients were submitted to laparotomy (a linear ultrasound probe was used). The primary endpoint was ovarian sparing surgery (oophoroplasty).
Results Among the 82 cases identified, only 36 met the inclusion criteria for the present study. Out of these cases, 25 underwent intraoperative ultrasound, and 11 did not. There were no significant differences in arterial hypertension, diabetes, smoking history, and body mass index for the two groups (p = 0.450). Tumor diameter was also similar for both groups, ranging from 1 cm to 11 cm in group A and from 1.3 cm to 10 cm in group B (p = 0.594). Tumor histology confirmed mature teratomas for all of the cases in group B and for 68.0% of the cases in group A. When the intraoperative ultrasound was performed, a more conservative surgery was performed (p < 0.001).
Conclusion The use of intraoperative ultrasound resulted in more conservative surgeries for the resection of benign ovarian tumors at our center.
Chronic Distal Radioulnar Joint Dislocation: A Case Report
Authors: Fernandes Leonor , Sousa João , Cruz Fernando 
Published: November 2019

AbstractDislocation of the distal radioulnar joint (DRUJ) usually occurs associated with a distal radius fracture. An isolated dislocation, without a radius fracture, is a rare situation.We present a case of neglected isolated DRUJ dislocation in a 30-year-old manual laborer. The treatment was performed 4 months after the initial injury. Open reduction and fixation were performed. This resulted in a stable, pain-free joint, and the patient resumed his previous work.Surgical techniques of foveal reattachment and dorsal capsuloplasty have been described for chronic DRUJ instability. An isolated and dislocated DRUJ is an uncommon injury that may be misdiagnosed and initially mistreated. There haven't been many reports in the literature of a case such as this.

Published: November 2019

Abstract
Background Hospitals across the country are investing millions of dollars to adopt new Health Insurance Portability and Accountability Act (HIPAA)-compliant secure text messaging systems. However, in nearly all cases, these implementations are occurring without evaluation of their impact on patient care.
Objective To evaluate perceived impact on patient care and workflow of new text messaging system implemented in obstetrics at Yale-New Haven Hospital and to inform guidelines for future implementations in emergent settings.
Methods A new HIPAA-compliant texting system was implemented in obstetrics in 2016. Before implementation of the new system, residents and nurses were surveyed on perceived effect of communication system (pagers with text receiving, service mobile phones, personal cell phones) on clinical workflow and patient care using 5-point Likert scale and open-ended questions. Following roll-out (1 and 6 months), both teams were surveyed with same questions. Results were compared using Wilcoxon–Mann–Whitney test (0–1 months and then 0–6 months). Open-ended question results were qualitatively compared for recurrent unifying themes.
Results In both nursing and resident domains, 1 month after implementation, the new communication system was perceived to significantly improve efficiency and patient care across all metrics. After 6 months, this effect decayed in nearly all categories (including efficiency, real-time communication, and knowledge of covering provider). The exception was nurse's knowledge of which resident to contact and resident's timely evaluation of patient, for which we observed sustained improvements. System shortcomings identified included interrupted connection (i.e., dropped calls), dysfunctional and inaccurate alert system, and unclear identification of the covering provider.
Conclusion A new text-messaging–based communication system may improve efficiency and patient care in emergent settings, but system shortcomings can substantially erode potential benefits over time. We recommend implementers evaluate new systems for a set of specific functional requirements to increase probability of sustained improvement and decrease risk of poor patient outcomes.
Participation patterns of the rainfall index insurance for pasture, rangeland and forage programme
Authors: Goodrich Brittney , Yu Jisang , Vandeveer Monte 
Published: November 2019

AbstractUsing a novel policyholder-level data set, we analyse participants’ choices of 2-month index intervals in the Rainfall Index for Pasture, Rangeland and Forage (RI-PRF) insurance programme. We first provide a conceptual model that illustrates participation patterns of the rainfall index insurance. We then connect these predicted patterns to some empirical evidence from the policyholder-level data set, which is a subset of data provided by the USDA Risk Management Agency for all RI-PRF participants in Nebraska and Kansas during the years 2013–2017. Because the correlations between forage yield and precipitation and the expected premium subsidy vary by month, different degrees of risk aversion may predict distinctively different choices of the 2-month intervals. Using cluster analysis, we group the participants with similar allocation patterns across the 2-month intervals. We observe that the number of participants displaying relatively low levels of risk aversion increase over time. We connect this to the fact that premium subsidies and producer returns associated with non-growing season (risk-increasing) months are often greater than those for growing season (risk-reducing) months, and this has important implications for policy design. Our findings suggest that more research in this area could assist policymakers in keeping the RI-PRF programme in line with its objective of reducing risk for livestock producers.
Royal jelly reduces depression-like behavior through possible effects on adrenal steroidogenesis in a murine model of unpredictable chronic mild stress

Published: November 2019

ABSTRACTRoyal jelly (RJ) is used as a dietary supplement for human health promotion. Recently, a clinical trial has reported that RJ improved mental health. The present study was conducted to experimentally support the clinical effect of RJ on mental health and to further elucidate the mechanisms of action of RJ. RJ and an ethanol extract of RJ, which contains fatty acids but not proteins, inhibited an unpredictable chronic mild stress (UCMS)-induced increase in immobility time, a depression-like behavior, in the tail suspension test. DNA microarray analysis of the adrenal grand revealed that the expression of genes involved in cholesterol metabolism was up-regulated in response to UCMS exposure and that RJ suppressed expression of genes related to cholesterol synthesis and transport. These results suggested that RJ improves stress-induced depression-like behavior by regulating adrenal steroidogenesis and that fatty acids contained in RJ partly contribute to the antidepressant effect of RJ.

Published: November 2019

ABSTRACT
Corn fibre xylan (CX) shows high resistance to enzymatic hydrolysis due to its densely decorated side chains. To find enzymes capable of hydrolyzing CX, we isolated a bacterial strain (named H2C) from soil, by enrichment culture using non-starch polysaccharides of corn as the sole carbon source. Analysis based on the 16S rRNA sequence placed strain H2C within genus Paenibacillus. Enzymes were purified from supernatant of culture broth of strain H2C based on solubilizing activities toward CX. Four enzymes, Xyn5A, Xyn10B, Xyn11A, and Xyn30A, were successfully identified, which belong to glycoside hydrolase (GH) families, 5, 10, 11, and 30, respectively. Phylogenetic analysis classified Xyn5A in subfamily 35 of GH family 5, a subfamily of unknown function. Their activities toward beechwood xylan and/or wheat arabinoxylan indicated that these enzymes are β-1,4-xylanases. They showed high solubilizing activities toward a feed material, corn dried distiller’s grains with solubles, compared to five previously characterized xylanases.

Published: November 2019

Abstract
A graphene/In2O3 bilayer (termed as GI-bilayer) is proposed as a transparent conducting electrode with remarkably improved areal-uniformity. To fabricate this new structure, an In2O3 layer with a thickness of less than 50 nm was grown by atomic layer deposition and then a graphene layer was grown by chemical vapor deposition and subsequently transferred onto the as-grown In2O3 layer. Electrical and optical properties of the GI-bilayer were systematically studied to verify effects of the underlying In2O3 layer. Hall measurements and following analysis showed a conductance enhancement of the GI-bilayer owing to p-type doping of graphene. Specifically, Raman analysis and ultraviolet photoelectron spectroscopy were performed to prove p-type doping of the graphene in the GI-bilayer. In addition, the GI-bilayer exhibited the significantly improved uniformity of the sheet resistance compared to that of a conventional monolayer of graphene. There was a duality on the role of the In2O3 underlayer in the GI-bilayer. It acted as a dopant layer to the graphene and lowered the sheet resistance from 863 to 510 Ω/sq as well as compensated microscale defects on graphene. More importantly, the In2O3 underlayer resulted in the extremely reduced standard deviation of sheet resistance from 150 to 7.5 Ω/sq over the area of 49 cm2.
Formation of salinity and density vertical stratification of the Black sea
Authors: Korotaev G K 
Published: November 2019

AbstractA simple model of the haline and density stratification evolution in the cylindrical rotating basin under the influence of buoyancy fluxes through the side border is proposed in the work based on the dimension analysis. The model is based on the assumption that the sharp pycnocline and two different circulation cells in the vertical plane above and below pycnocline. The model shows that the typical time of vertical circulation cell modification is determined by the inertia of the main body of waters in the basin. Also under fixed ambient conditions, one should expect pycnocline sharpening and increased intensity of vertical circulation cells over time. The model application to describe the climatic changes of the Black Sea haline stratification is discussed. It is asserted that the response of a marine basin to changes in the external conditions depends significantly on the inertia of a main water body. It is noted that this result is of importance not only for the Black Sea, but also for the World Ocean. This effect explains the slow change in the meridional heat transport even in case of considerable variations of deep convection at high latitudes.

Authors: Lemanov V V , Lukashov V V , Sharov K A 
Published: November 2019

Abstract
For the outflow of jets of various gases from long round tubes, the mode of transition to turbulence through the intermittency mechanism in the near field of the jet was experimentally detected for the first time. This mode is realized in the range of Reynolds numbers of 1900-3200, when inside the jet source, a laminar-turbulent transition occurs in the tube. The reasons of intermittency are turbulent spots (puff). These localized turbulent structures are formed inside the pipe, have a length of about 10-30 pipe diameters in the jet and occupy the entire transverse size of the jet flow.

In this paper we will focus on a promising technology of thermochemical treatment using the energy of the exothermic reaction of the interaction of two inorganic salts pumped into the reservoir in the form of an aqueous solution. The technology is environmentally safe and effective for intensification of production at low-yield wells of “old” layers and for low-permeable layers of unconventional high-viscosity oil. The authors created a mathematical model of the process and conducted a series of numerical studies that form the basis of field experiments to test technology at various fields in Russia.

Some peculiarities of superheated water flow in contracting-expanding nozzles and their influence on droplet dimension distribution in an atomized water plume
Authors: Zalkind V I , Zeigarnik Yu A , Nizovskiy V L , Nizovskiy L V , Schigel S S 
Published: November 2019

Abstract
New calculation data on superheated metastable water flow in atomizing Laval type nozzles is presented. The calculating model is discussed on the assumption of predominating nucleation role in liquid atomization. The Mach number variation is presented for diffuser part of the nozzle taking into account the sound velocity variation in a vapor-liquid system. The new criterion, based upon experimental and calculating data, which determines the reaching of full-flashing regime, is proposed for contracting-expanding nozzles. The submicron mass fraction is considered to be a function of dimensionless parameter, which is the critical radius bubble surface tension energy ratio to chemical potential of phase transition for critical bubble radius at certain pressure drop.

Authors: Skiba S S , Yu Manakov A 
Published: November 2019

Abstract
Impact of different parameters on the decomposition rates of hydrate at negative temperatures with depressurisation method has been studied. In previous work it was demonstrated that decomposition rates of hydrates suspensions in oil at static conditions can be limited by the self-preservation phenomenon. Our experimental research shows that appearance of self-preservation depends on many parameters such as components composition of oil, presence of shear in the system while decomposing hydrates and probably on the history of the sample.

Authors: Larionov K B , Mishakov I V , Slyusarsky K V 
Published: November 2019

Abstract
The processes of oxidation, ignition and combustion of bituminous coal containing 5 wt.% of activating agent (Cu(NO3)2) was studied. The experiment was performed using high-speed video recording of the combustion process of the researched coals in combustion chamber at a temperature of 700°C in the air at atmospheric pressure. Analytical assessment of the characteristics of ignition and combustion processes of the researched coals was carried out based on the obtained results. It was established that addition of Cu(NO3)2 promoter leads to a significant decrease of the time characterizing the delay in the beginning of coal ignition (in 2 times). Effect of the activating additive was also expressed in formation of flame during coal combustion at the stage of volatile substances separation with periodic formation of characteristic flashes formed as a result of decomposition of copper nitrate in the pores of the carbon matrix. This contributed to intensification of the release process of relatively large volume of combustible gases. The obtained results were compared with previously obtained data of the oxidation process of these coals with activating additives of copper salts by thermogravimetric analysis.

Published: November 2019

Abstract
A problem of temperature measurements under a pulse impact on a sample in a case of short-time wind tunnel experiments has been studied. Large errors in temperature definition of the sample wall leads to large errors in heat flux calculation, based on temperature change. The hypothesis on the reason of this error has been examined in the paper and the method of deconvolution has been proposed to improve heat flux calculation.
