Abstract
Background Beta-glucans are effective in binding bile acids (BA) thereby
lowering cholesterol concentration. This might contribute to the beneficial
effects of the consumption of β-glucan-rich foods like oatmeal on
glucose homeostasis.
Objective We measured BA serum concentrations in patients with
uncontrolled type 2 diabetes (T2DM) to investigate the effect of two days of
oatmeal treatment on BA concentration as compared to a conventional T2DM-adapted
diet.
Methods The OatMeal And Insulin Resistance study was performed as a
randomized, open label crossover dietary intervention study with consecutive
inclusion of 15 patients in an inpatient clinical setting. Bile acids were
measured by high-resolution mass spectrometry. For statistical analysis, the
differences in the concentration of serum BA and laboratory parameters between
the fifth day and the third day of each inpatient stay were calculated and the
effect compared between both phases by using the Wilcoxon test.
Results Whereas there was a mean decrease in total BA following oatmeal
treatment (−0.82±1.14 µmol/l), there was
no decrease following the control treatment. Glycocholic acid was lower after
oatmeal treatment but higher following control treatment
(−0.09±0.17 vs.
0.05±0.11 µmol/l). The reduction in total BA was
directly correlated with a decrease in proinsulin during the oatmeal phase.
Decreases in blood lipids or apolipoproteins were mostly greater after oatmeal
treatment, but these differences were not statistically significant.
Conclusion Two days of oatmeal diet led to significant reductions in
total BA as compared to a diabetes-adapted control diet. The magnitude of BA
reduction was directly correlated with a decrease in proinsulin.

Abstract
Objective Streptococcal toxic shock syndrome (STSS) is a very rare and severe entity from among the invasive diseases caused by Streptococcus pyogenes, whose characteristics, treatment, morbidity, and mortality are little known in pediatrics. The aim of this study was to determine its prevalence and the characteristics of its presentation in the emergency department (ED) in Spain.
Methods This is a descriptive and observational study. Patients from 1 month to 18 years of age, admitted to the ED with a final diagnosis of STSS between 2009 and 2014, were included. Patients whose parents or guardians did not allow informed consent were excluded.
Results Nine cases were diagnosed (1/100,000 consultations); the median average age was 2 years, and five were girls. No patient had a significant medical history. The most frequent reason for consultation was fever (9/9), followed by respiratory symptoms (6/9). Six presented in the ED with shock. Seven were diagnosed with pleuropneumonia, one with meningitis, and one with necrotizing fasciitis. All patients required admission at the pediatric intensive care unit, mechanical ventilation, and inotropic support. All had a complete recovery.
Conclusion STSS is a rare entity in the ED affecting healthy patients who presented respiratory or otorhinolaryngology disease. In our patients, nonspecific clinical manifestations and its rapid progression to shock are shown, meaning the importance of bearing this entity in mind in the emergency room. Understanding the epidemiology and clinical manifestations of this syndrome in our work area helps pediatricians to recognize it and to initiate the appropriate treatment at an early stage, which helps engender a quick and effective approach, essential for a favorable prognosis.

Published: January 2020

Abstract
Objective Lower respiratory tract infections (LRTI) are one of the most important causes of morbidity and mortality in childhood. Hypoxemia, pulmonary hypertension (PH) due to pulmonary vasoconstriction, and heart failure due to various causes are the most important risk factors for mortality in LRTI. The aim of this study was to investigate characteristics of the patients with LRTI and the frequency of PH that developed secondary to LRTI.
Materials and Methods The study included 70 patients who were diagnosed as having LRTI clinically and radiologically between January 2012 and March 2013 at Department of Pediatrics, Konya Training and Research Hospital. Age, sex, risk factors for LRTI, symptoms and physical examination findings, laboratory tests, and Doppler echocardiography findings of the patients were retrospectively reviewed.
Results Of the patients, 44 (62.9%) were male and 26 (37.1%) were female. Thirty-seven (52.9%) patients were younger than 1 year, and the mean age was 2.5 ± 3.11 years. The most common symptoms of the patients were cough and fever. Rhonchus, retraction, and crackles were found to be the most common findings in physical examinations. Heart failure was found in 10% of patients and PH was detected in 8.6% through Doppler echocardiography. Development of heart failure and the presence of bilateral patch infiltration on posteroanterior chest X-rays were significantly more frequent in patients with PH. Some 42.9% of patients had at least one viral agent in their nasopharyngeal swabs. The most common viral agents were respiratory syncytial virus and rhinoviruses.
Conclusion PH may develop during the course of LRTI in children. Given that the development of PH can cause life-threatening complications such as heart failure, affected patients should be kept under close follow-up. It should be remembered that PH is more likely to develop in patients with bilateral patch infiltration on chest X-ray.

Published: January 2020

AbstractThis study aims to compare the clinical outcomes of the nickel–titanium arched shape–memory alloy connector (hereafter referred to as the ASC) and tension band fixation for the treatment of transverse patellar fractures. We retrospectively analyzed a total of 257 patients with transverse patellar fractures who were treated at our emergency orthopaedics department from March 2010 to March 2017. Either an ASC or the Kirschner wire (K-wire) tension band had been used to treat these fractures according to surgeons' experience and preference. We compared operative details, postoperative recovery, and postoperative knee function at 6 months. In terms of surgical duration, blood loss, incision length, length of hospital stay, and postoperative complications, patients in the ASC group showed significantly better results than patients in the K-wire group (p < 0.05). There were no significant differences between the two groups in terms of fracture healing time, knee mobility, and the Boström score at the postoperative 6-month evaluation (p > 0.05). Though, there were similar functional outcomes between two groups whose transverse patellar fractures were different methods, we found that the ASC method was a more reliable, more minimally invasive, and safer treatment option than the tension band wiring method using K-wires, resulting in less tissue damage, shorter surgical duration, shorter length of hospital stay, and fewer complications.
Entanglement-based 3D magnetic gradiometry with an ultracold atomic scattering halo
Authors: Shin D K , Ross J A , Henson B M , Hodgman S S , Truscott A G 
Published: January 2020

Abstract
Ultracold collisions of Bose–Einstein condensates can be used to generate a large number of counter-propagating pairs of entangled atoms, which collectively form a thin spherical shell in momentum space, called a scattering halo. Here we generate a scattering halo initially composed of pairs in a symmetric entangled state in spin, and observe a coherent oscillation with an anti-symmetric state during their separation, due to the presence of an inhomogeneous magnetic field. We demonstrate a novel method of magnetic gradiometry based on the evolution of pairwise correlation, which is insensitive to common-mode fluctuations of the magnetic field. Furthermore, the highly multimode nature and narrow radial width of scattering halos enable a 3D reconstruction of the interrogated field. Based on this, we apply Ramsey interferometry to realise a 3D spatial reconstruction of the magnetic field without the need for a scanning probe.
Study of temperature dependent viscosity of different types of engine used oils
Authors: Raţiu S , Alexa V , Josan A , Cioată V G , Kiss I 
Published: January 2020

Abstract
The article presents a study on the change in kinematic viscosity with the temperature for three samples of synthetic used oil (SAE 5W-30). Samples were taken after a 10,000 km run on the occasion of periodically changing oil from three engines with close cylindrical capacities (one diesel engine – VW 1.9 TDI, one gasoline engine – Audi 1.8 Turbo and one spark engine – Audi 1.8 Turbo, working with GPL). Comparatively, viscosity measurements were made for the same oils before being introduced into the engines. The kinematic viscosity was measured experimentally using the Brookfield viscometer from 5 to 5 degrees Celsius. To eliminate the errors, the measurements were made under the same conditions for all samples, being repeated three times, the values taken into consideration for a given temperature being made up of averages of the three measurements.

Abstract
The paper involve testing of various engine oils – synthetic and semi – synthetic – in terms of viscosity change at different temperatures and the degree of wear. New and used oils were compared. This is an important issue for determining the reliability of motor vehicles, anticipated repairs and maintenance. As a result of the process of exploitation, engine oils are subjected to physicochemical changes. The impact on the deterioration in the condition of the lubricating liquid have, among others high pressure, temperature, pollution or oil oxidation. Therefore, it is necessary to change the engine oil after the mileage recommended by the producer . However, these recommendations may not be adequate for the actual consumption of liquids, which is determined by the technical condition of the engine and the course of the operation process. Determining the optimal replacement time is an important issue due to the reduction of operating costs and reduction of emissions of environmentally harmful exhaust. For this purpose, the viscosity depending on the temperature of different oils with various degrees of wear, tear, and obsolescence were measured. Characteristic points were determined and a mathematical model describing these changes was created. It was noticed that the greatest changes in viscosity occur at a temperature of 0 °C to 40 °C, whereas from 40 °C the viscosity changes appear in a smaller range for all oils and the viscosity was below 100 mPa·s. Results of comparing the new and used oil was evaluation of the change of their lubricating properties. The aim of this paper was to conduct viscosity tests of selected engine oils using a rotational viscometer in order to check the degree of engine oil consumption due to the degree of exploitation.

Indetermination versus incompatibility in dynamic systems with dry friction
Authors: Alaci S , Ciornei F C , Pentiuc R D , Ciornei M C , Românu I C 
Published: January 2020

Abstract
The study of the dynamical behavior of a system becomes really complex when friction forces are introduced in calculus since they directly depend on the values of the normal reactions and on the motion of the system, but the motion, at its turn, depends upon the forces from the system. The analysis is more difficult when dry friction, characterized by inequalities, is present between the parts of the system. When inequalities are involved in dynamical equilibrium equations, theoretically simultaneous equilibrium states may occur. In scientific literature there are famous examples supporting this statement. The present paper presents the dynamical study of a simple system, namely a ball obliged to roll in a groove with flat walls.
It is proved experimentally that the motion of the ball is a planar one. The dynamical analysis of the system with planar motion leads to an undeterminate system of equations and therefore the spatial approach of the system is required. After writing the equations of the spatial motion of the ball, an incompatible system of equations is obtained.
Upon the efficiency of gear transmissions

Published: January 2020

Abstract
The work proposes an experimental method and device for finding the efficiency of the spur gear mechanism. A simple device that can measure the work lost by friction only in teeth contacts was constructed. The test rig was designed to ensure measurements for two configurations with the same inertial characteristics but for different gear friction conditions. The principle is based on the difference of energy losses for the two mounting cases that provides the energy lost by friction between flanks. Recording the variation of the decreasing rotational speed for the case of constant actuating torque, the frictional losses can be deduced. The values of the efficiency obtained are smaller than in literature. The method is simple and rapid and the experimental results validate the theoretical model.

Abstract
Among the materials, often used in manufacturing details subjected to cavitation erosion, such as pump impellers, propellers, fittings, valves body, etc. there are also CuZnPb brasses. Their use in molded or laminated condition, for pieces subjected to cavitation, is of short duration due to degradation through the erosion. For this reason, any method of increasing the extension of life, is beneficial. In this direction are enrolled also the results obtained in this paper, obtained by the cavitation tests made on CuZn39Pb3 brass, subjected to three the volumetric heat treatment regimes. Appreciation of cavitation resistance, of each treatment regime, is based on the evolution of average durability

Causes analysis of occurrence of the terrain surface discontinuous deformations of a linear type
Authors: Orwat J 
Published: January 2020

Abstract
In the article some area located in the mining terrain of hard coal mine in Poland has been analysed. In this area the discontinuous deformations of a linear type, for example faults and ground steps have been occurred. They had the substantial dimensions and appeared near or under the residential buildings. That’s why they are so dangerous. In this paper the causes of their occurrence have been analysed. Probably a main reason of their creation is an intensive, underground mining exploitation which in two hard coal seams has been carried out. These seams were located at a relatively small depth, inclined at a significant angle, exploited by the use of a longwall system with a roof rocks cave-in and had a considerable thickness. All of these things contributed to accumulation of the adverse stresses concentrated in one area. Release of stresses caused by an extraction of hard coal contributed to the formation of numerous faults.

Abstract
Speaking of the biggest innovations for the manufacturing industry of the day, we are talking about intelligent production systems with “self-aware”, “self-contemplative and” self-sustaining “capabilities. Building such an intelligent system that is adapted and predictable provides the aforementioned capabilities in production, processes and machines. The intelligent system is able to combine various technologies and techniques for mixing statistical data, data, and artificial intelligence methods. Cigarette production is selected because it is highly serial. In such production, the use of expert systems in quality management in this area is not sufficiently developed, and with direct management, it generates great savings. Mistakes and errors are inversely proportional to productivity. This paper deals with the application of an intelligent system that uses the key principle of lean production. We need to build an adaptive system for predictive error and reduce the machine’s failure time in the cigarette industry.
Exact solution for the severity of transverse cracks in prismatic beams
Authors: Tufisi C , Gillich G R , Hamat C O , Biro I , Gillich N , Nedelcu D 
Published: January 2020

AbstractWe propose herein a mathematical relation to calculate the severity of transverse cracks which affect a prismatic beam. It is known that the damage severity depends on the depth of the crack located at the slice on which the biggest bending moment is achieved. The frequency drop due to this crack is proportional to the severity associated with it. For all other crack locations, the effect is diminished in relation to the curvature registered at the affected slice. It is essential to obtain a relationship to correctly express the severity with respect to the crack depth. To find it, we designed a model of a cantilever beam with cracks located near the fixed end. We observed that the deflection of the beam’s free end increases the closer the crack to the fixed end is, but after a certain limit, the deflection decreases. We concluded that the deflection decrease occurs because the deformation around the crack is restricted by the fixing condition. To find the true severity, we derived the pseudo-severity for six crack positions and estimate the severity using the linear and second-order polynomial regression curves. Next, we used twelve points for interpolation and found a very similar severity. Finally, we performed modal analysis for the beam with cracks at different positions and found the mathematical relation developed to predict frequency changes that involves the severity provides accurate results.

Published: January 2020

Abstract
The objective of the paper is to apply the reverse engineering in the mechanical field to reconstruct the geometry of two types of model turbine blade: axial blade and Pelton bucket. To generate the point clouds, the geometry of the blades was scanned by laser and digital photogrammetry. The Creaform HandySCAN 700 laser scanner and VXelements software were used to get the point cloud of the blades. For digital photogrammetry the NIKON D610 photo device and Agisoft Photoscan software were used to get the point cloud of the blades. Finally, the point clouds generated were compared in GOM Inspect software to highlight the deviations between them.
