Published: June 2019

One of the promising ways in environmentalizing marine internal combustion engines is the neutralization of harmful substances in exhaust gases through particular gas recirculation (EGR-technology). However, the use of such techniques conflicts with the engine's energy efficiency. In the work presented, the scheme-design solution of the exhaust gas recirculation system with using the heat of recirculation gases by an ejector refrigeration machine for cooling the air at the intake of ship's main engine is proposed. The effect of using the heat of recirculation gases for cooling the air at the intake of the engine is analyzed taking into account the changing climatic conditions for a particular vessel's route line. It is shown that the use of an ejector refrigeration machine reduces the air temperature at the entrance of the main engine by 5-15 ° С, which reduces the specific fuel consumption by 0.5-1.5 g/(kW∙h). This reduces emissions of harmful substances when the engine is running with recirculation of gases, in particular, NOx by 30-35%; SOx by 10-12%.

Published: June 2019

Information on surface tension is necessary for modeling boiling processes in nanofluids. It was shown that the problem of predicting the surface tension of complex thermodynamic systems, such as nanofluids, remains outstanding. It should be noted that the surface tension of liquids and the saturated vapor pressure are due to a specific intermolecular interaction in the region of spatial heterogeneity of the substance (surface layer). Moreover, the compositions of the surface layer of nanofluid and its liquid phase are not equal. The presence of nanoparticles in the base fluid affects the composition of the surface layer of liquids. However, there are no methods for determining the composition of the surface layer of nanofluids and this fact complicates establishing the dependence of the surface tension on the state parameters of nanofluids. It should be mentioned that the number of possible methodological errors in measurements of the saturated vapor pressure of nanofluids is significantly lower than for the surface tension measurements. Therefore, in the development of models for predicting the surface tension, scientific and practical interest has establishing the relationship between the surface tension and the saturated vapor pressure of nanofluids. In the presented work, we consider the nanofluids of isopropanol/Al2O3 nanoparticles and o-xylene/fullerenes C60. Saturated vapor pressure and surface tension of nanofluids of isopropanol/Al2O3 nanoparticles have been studied in the temperature range 293 – 363 K and concentrations of Al2O3 nanoparticles 0-8.71 g/kg. Measurement of saturated vapor pressure and surface tension of nanofluids of o-xylene/fullerenes C60 have been performed in the temperature range 283 – 348 K and the concentration of C60 0-7.5 g/kg. It is shown that additives of Al2O3 nanoparticles and fullerenes C60 lead to a decrease in the surface tension and increase in the saturated vapor pressure. It is shown that there is a universal dependence between the reduced surface tension and saturated vapor pressure for the researched nanofluids.
The shape of road markings for visibility computations
Authors: Crescenzo Giuseppe , Villa Céline , Brémond Roland , Vignali Valeria , Lantieri Claudio , Simone Andrea 
Published: June 2019

Road markings visibility is usually assessed by means of the visibility level (VL). Several models have been developed to calculate the visibility distance on the road (Detect/PCDetect, Carve/Tarvip, Cost 331 and CIE 73). These models all approximate the visibility of a marking by estimating the diameter of an ‘equivalent’ disc. In this process, speculative hypotheses are made to calculate this diameter, labelled the equivalent area hypothesis, the equivalent perimeter hypothesis or the equivalent width hypothesis. To compare these hypotheses, a psychophysical experiment was conducted with eight participants and 120 stimuli. It was found that the merit of each hypothesis changed with the diameter of the equivalent disc. Above 0·1°, all the hypotheses gave good results, but the equivalent area hypothesis was found to be the best. Below 0·1°, the equivalent width hypothesis was more accurate, but further investigations are still needed.

Published: June 2019

Introduction. Direct primary care (DPC), a fee for membershiptype of practice, is an evolving innovative primary caredelivery model. Little is known about current membershipfees, insurance billing status, physician training, and patientpanel size in DPC practices. This study aimed to obtain currentdata for these variables, as well as additional demographicand financial indicators, and relate the findings to the HealthyPeople 2020 goals. It was predicted that DPC practices would(1) submit fewer claims to insurance, (2) have decreased membershipfees, (3) be primarily family medicine trained, and(4) have increased the projected patient panel size since 2005.
Methods. An electronic survey was sent to DPC practices(n = 65) requesting location, membership fees, projectedpatient panel size, insurance billing status, training,and other demographic and financial indicators. Datawere aggregated, reported anonymously, and compared totwo prior characterizations of DPC practices done in 2005.
Results. Thirty-eight of 65 (59%) practices responded to the2015 survey. The majority of respondents (84%) reported usingan EMR, offering physician email access (82%), 24-hour access(76%), same day appointments (92%), and wholesale labs (74%).Few respondents offered inpatient care (16%), obstetrics (3%),or financial/insurance consultant services. Eighty-eight percent(88%) of practices reported annual individual adult membershiprates between $500 and $1,499, decreased from 2005 where81% reported greater than a $1,500 annual fee. The proportion ofpractices who submit bills to insurance decreased from 75% in2005 to 11% in 2015. Fifty-six percent (56%) of practices reportedprojected patient panel size to be greater than 600, increasedfrom 40% in 2005. Family medicine physicians represented 87%of respondents, markedly different from 2005 when 62 - 77% ofDPC respondents were general internal medicine physicians.
Conclusions. Most DPC practices no longer submit to insuranceand are family medicine trained. Comparedwith the previous sampling, DPC practices report decreasedmembership fees and increased projected panelsize. These trends may signify the DPC movement’sgrowth in application and scope.

Published: June 2019

Introduction. With arthroscopic techniques being used, the importanceof knot tying has been examined. Previous literaturehas examined the use of reversing half-hitches on alternatingposts (RHAPs) on knot security. Separately, there has been researchregarding different suture materials commonly used inthe operating room. The specific aim of this study was to validatethe effect of different stacked half-hitch configuration anddifferent braided suture materials on arthroscopic knot integrity.
Methods. Three different suture materials tied withfive different RHAPs in arthroscopic knots were compared.A single load-to-failure test was performed andthe mean ultimate clinical failure load was obtained.
Results. Significant knot holding strength improvement wasfound when one half-hitch was reversed as compared to baselineknot. When two of the half-hitches were reversed, therewas a greater improvement with all knots having a mean ultimateclinical failure load greater than 150 newtons (N). Comparisonof the suture materials demonstrated a higher meanultimate clinical failure load when Force Fiber® was used andat least one half-hitch was reversed. Knots tied with eitherForce Fiber® or Orthocord® showed 0% chance of knot slippagewhile knots tied with FiberWire® or braided fishing linehad about 10 and 30% knot slippage chances, respectively.
Conclusion. A significant effect was observed in regards to bothstacked half-hitch configuration and suture materials used onknot loop and knot security. Caution should be used with tyingthree RHAPs in arthroscopic surgery, particularly witha standard knot pusher and arthroscopic cannulas. The findingsof this study indicated the importance of three RHAPsin performing arthroscopic knot tying and provided evidenceregarding discrepancies of maximum clinical failure loads observedbetween orthopaedic surgeons, thereby leading to bettersurgical outcomes in the future.

The Rabbit Listened by C. Doerrfeld
Authors: Radmanovich Rachel 
Published: June 2019

Doerrfeld, Cori. The Rabbit Listened. Dial-Penguin Random House, 2018.
This picture book, both written and illustrated by Cori Doerrfeld, is a lovely book for encouraging listening skills and overall calm in children aged 1-5. As the implicit meaning can run very deep, adults would also benefit from the messaging. It is about a young girl, a toddler named Taylor, who is grieving. At the beginning of the story, Taylor is in her comfy pyjamas and has just finished building a substantial wooden block tower. It then comes crashing down, providing a strong, simple, and non-threatening metaphor to the adversities of everyday life.
As a result, Taylor is very sad and would like to express her feelings in a certain way, yet she is unsure of what way that is or is unable to articulate her emotion. Several different types of animals come by to try to cheer her up. A chicken tries to get her to talk (and will not be quiet), a bear tries to get her to shout (displaying anger), etc. The variety of animals chosen is wonderful symbolism that kids can relate to and are a great visual metaphor for feelings. At the end of the story, Taylor realizes she just wants to be alone and be quiet. The rabbit was the only animal to recognize this. The rabbit just listened.
The story includes soft, calm, and simple crayon-type illustrations that are so cute, they are almost tactile. The background of each page is stark white, placing the focus of the story solely on the characters. This book would appeal to just about anyone reflecting on their feelings during a time of loss, difficulty, or even trauma. As some of the less obvious metaphors would be lost on a younger audience, this book is a great stepping stone to begin and facilitate conversations between children and adults about feelings and how to cope with challenging life circumstances.

The Remember Balloons by J. Oliveros
Authors: Townsend Deanna 
Published: June 2019

Oliveros, Jessie. The Remember Balloons. Illustrated by Dana Wulfekotte, Simon & Schuster Books for Young Children – Simon and Schuster, 2018
This beautifully written story tells of a young boy and his dear relationship with his aging Grandfather. Connected through balloons that hold memories and stories, the young boy notices his Grandfather begins to lose his balloons and eventually his memory, even of knowing his beloved grandson. Confused and upset, the young boy cannot understand why this is happening and tries in vain to save his Grandfather’s balloons. Saddened, the boy seeks his parent’s help whereby they show him that he now has a whole new set of balloons—his Grandfather’s. In acquiring these treasured memories, the young boy discovers a new way to be with his Grandfather through retelling him all his old stories.
Illustrated in pencil sketch with minimal colour other than the varied and vibrant balloons, Oliveros speaks to children in a beautifully relatable manner about memories and stories and the connections to the people we cherish. It gently acknowledges the difficult changes in relationships as a loved one experiences the changes of aging and memory loss and guides the reader to find new ways to experience their stories and build new connections.
The subtle acknowledgement of mixed-race families and friend groups also lends itself to a realistic and contemporary view of family and culture, further strengthening the relatability of this story to a wider readership.
Recommended and appropriately written for ages 5-9 years, the book’s themes of keeping our memories close in our varied balloons and maintaining our connections with family even as relationships change, lends itself to a far greater age demographic.

Hidden Figures: The True Story of Four Black Women and the Space Race by M.L. Shetterly and W. Conkling
Authors: Kim Melanie 
Published: June 2019

Shetterly, Margot L and Winifred Conkling. Hidden Figures: The True Story of Four Black Women and the Space Race. Illustrated by Laura Freeman, Harper, 2018.
Based on The New York Times bestselling book and Academy Award-nominated movie, this historical picture book was inspired from the true story of the first four black women who worked at NASA. Author Margot Lee Shetterly follows the careers of these women who were really good at math, and their achievements as black women. Hidden Figures is illustrated by Laura Freeman, who has illustrated over twenty children’s books. To illustrate this book, she read the original book, watched the movie, and did research on NASA’s website to view archival photos. Freeman’s in-depth research has resulted in powerful images that enable the reader to feel the racial discrimination of the time. In addition, through the illustrations, the reader is able to see what the machine computers looked like at the time. An illustrated timeline and glossary page are provided at the end of the book; these pages will help readers to visualize the story. These illustrations will provide interest for all ages.
The text is written in simple English. However, there are some scientific terms. Therefore, for younger children, reading this book with adults or reading buddies is recommended. Moreover, going over the glossary pages with children before they read the book will help children to understand the story better. Overall, this book will help children to be aware of sexism and racism and the achievements of black women in the past.
Hidden figures is highly recommended for school libraries. Teachers can use this book as a cross-curricular resource for social studies, language arts, and health classes. The message from this book is for readers not to give up on achieving their goals. When children read this book, they can substitute their own difficult situation and get the courage to overcome obstacles.
