Published: June 2019

Objective: To study the specificities and parameters of the new, including innovative, freight and passenger electric locomotives, produced for domestic railways in the framework of the program of creating the new locomotives in 2004–2010. To analyze pull and energy efficiency parameters of direct current and alternating current electric locomotives. To estimate the maximum weight of trains and specific energy consumption of electric locomotives. To detect the advantages of new electric locomotives in comparison with those produced earlier. To develop guidelines on efficiency improvement of the new electric locomotives. Methods: Comparative analysis, methods of grade computations, linear regression analysis, power balance method. Results: The main design features and parameters of the new and earlier produced electric locomotives were studied, the former include the power of tractive motors, traction effort, as well as the speed at continuous rating of traction. The parameters of the new and earlier produced electric locomotives were compared. Key performance indicators of electric locomotives were analyzed, such as the maximum mass of a train and specific energy consumption on traction. The comparison of the above-mentioned indicators with performance indicators of earlier produced electric locomotives was given. According to calculation data and statistical data analysis the advantages of new electric locomotives were determined over those produced earlier. High performance of regenerative breaking was shown, specifically new electric locomotives. It was detected that in winter regeneration of electric energy was significantly reduced, in case of regenerative braking of passenger electric locomotives series EP1 with alternating current, as most of energy generated by tractive motors was spent on electric heating circuits of passenger cars. Guidelines on efficiency improvement of new electric locomotives were developed. Practical importance: The conditions in which new electric locomotives would implement the available advantages were determined, compared to those produced earlier. The elaborated offers make it possible to improve pull and energy efficiency of the new electric locomotives in operation.

Authors: Kononov Dmitriy
Published: June 2019

Objective: To improve the reliability of wrought wheels by means of fatigue enhancement of the latter, processed by use of disk turning. Methods: The creation in the disk skin layer the correct quality indices, such as magnitude and depth of residual stress occurrence, the level and depth of hammering, surface roughness. In order to fulfill the task, the required material of the tool cutting part is selected, tool design parameters are determined, cutting depth and feed, allowed for the required processing accuracy, surface roughness, residual stress the level and depth of hammering, is calculated. In the process of turning the cutting speeds are to provide optimum temperature in the cutting area, that is the temperature at which the operation in question results in minimum wear ratio of the cutter and induces compression residual stress. Results: It was discovered that the reduction of roughness level, hammering depth and residual compression stress formation increase the fatigue endurance of wheels. Cutting speeds (toolcutting speed, cutting depth and feed) were set for each segment of the disk surface (wheel rim section, midsection and hub section) outside and inside the wheel, in order to achieve optimum quality indices; the method of estimated determination of machined surface quality parameters of freight car wrought wheels was developed, depending on the cutting speeds taking into account temperature and force interactions of the machining tool and the machined part. Practical importance: The method of fatigue enhancement of the rolling stock wrought wheels when processed was developed. The basic requirements to values of wrought wheel discs quality parameters were formulated.

Authors: Kotenko Alexey , Grachev Andrey , Gogoleva Anastasiya , Shmanev Timofey
Published: June 2019

Objective: At present the majority of railway lines experiences serious difficulties in handling of the increased flow of freight trains with considerable amount of passenger traffic. In view of this there is a necessity to improve the level of train schedule stability by creating certain time slacks in it, which make it possible to eliminate errors. Methods: The methods of simulation, computational theory and construction of a train schedule graph were applied. Results: The method of train routing was developed on the basis of simulation of schedule configuration. The characteristics of schedule configuration and conditions of its creation were presented. The influence of trainhandling capacity efficiency coefficient on the choice of a configured train routing diagram was studied, as well as one of the vital factors, causing degradation of train schedule fulfillment stability – disagreement in train traffic. It was shown that in case of selecting a configuration it was necessary to increase the headway between consecutive trains after a bunch of trains, and if train overtaking is inevitable – to use the time of extra removal. In order to eliminate the consequences of disagreement in train traffic, it was proposed to increase intervals not between all trains, but to compensate the disagreement after passage of a number of trains, the latter should be specified on an individual basis. The assessment of compensating interval efficiency was fulfilled by means of removal coefficient calculation for different conditions on three options. It was concluded that the compensating interval not only reduces disagreement impact, but also improves train-handling capacity. The example of train schedule stability improvement was considered on the basis of applying configurations at “Malaya Vishera – Bologoye” section on down trains within the period of time from 11.30 pm to 7.30 am. Practical importance: Application of configurations makes it possible to achieve higher implementable levels of speed and train-handling capacity, leads to the detection of time slacks and time buffers, which considerably increase train schedule stability and, consequently, the stability of its fulfillment.

Authors: Grigoras Gheorghe , Neagu Bogdan-Constantin
Published: June 2019

In the paper, an improved smart meter data-based three-stage algorithm to calculate the power/energy losses in the three-phase networks with the voltage level below 0.4 kV (low voltage - LV) is presented. In the first stage, a loading function of input data was built having as main feature the working at the same time with files from the database of smart metering system (SMS) containing the hourly electricity records, and files including the characteristic load profiles established by the Distribution Network Operator (DNO) for the consumers with standard energy meters depending the following factors: consumption class, day and season. In the second stage, a function which is based on the work with the structure vectors was implemented to identify easy the configuration of analysed networks. In the third stage, an improved version of forward/backward sweep-based algorithm was proposed to calculate fast the power/energy losses to three-phase LV distribution networks in balanced and unbalanced regime. A real LV rural distribution network from a pilot zone belonging to a Distribution Network Operator (DNO) from Romania was used to confirm the accuracy of the proposed approach. The comparison with the results obtained using the DigSilent PowerFactory Simulation Package certified the performance of the algorithm, the mean absolute percentage error (MAPE) being 0.94%.
Idempotent Factorizations of Square-free Integers
Authors: Fagin Barry
Published: June 2019

We explore the class of positive integers n that admit idempotent factorizations n=pq such
that lambda(n) divides (p-1)(q-1), where lambda(n) is the Carmichael lambda function. Idempotent factorizations with p and q prime have received the most attention due to their cryptographic advantages, but there are an infinite number of n with idempotent factorizations containing composite p and/or q.
Idempotent factorizations are exactly those p and q that generate correctly functioning keys in the
RSA 2-prime protocol with n as the modulus. While the resulting p and q have no cryptographic utility and therefore should never be employed in that capacity, idempotent factorizations warrant study in their own right as they live at the intersection of multiple hard problems in computer science and number theory. We present some analytical results here. We also demonstrate the existence of
maximally idempotent integers, those n for which all bipartite factorizations are idempotent. We show
how to construct them, and present preliminary results on their distribution.

Authors: S. Eldesoky Amal , Eid Kamel , M. Abdullah Aboubakr
Published: June 2019

The deaf impairment is among the most substantial health problem worldwide, that can lead to various personal, economical, and social crisis. Therefore, it is critical for developing an efficient way to facilitate communication between deaf-dumb impaired and normal people. Herein, we have rationally designed a new digitally computerized and mobile smart system as an efficient communication tool between deaf impaired and normal Arabian people. This is based on two main steps, including creating a digital output for the hand gestures using gloves flex sensors equipped with a three-axis accelerometer that is controlled using a microcontroller. The digital results are compared to that in a words-based “database”, where Arabs use expressions not alphabet in their communication. The second step is translation or conversion the outputs of the first stage into written texts and voices. The newly developed system allows Arabian deaf to translate words of ordinary people into gestures using a speech recognition system with an impressive accuracy over 90 % without the needing for a webcam, colored gloves, and/or online translator. The presented system can be used on any android or windows.
Teacher's Attitudes as Knowledge Predictors
Authors: Quirós Oscar E. , Chaverri Gloriana , Iturralde-Polit Paula , Miranda Karen , Sandí-Ureña Santiago
Published: June 2019

Attitudes and behaviours towards the natural environment have been extensively studied in certain cultural settings during the last 40 years. In education, the teacher's ability to grasp the fundamentals of an academic subject may define his or her own attitudes towards that discipline; certainly the reverse is also valid. The correlations between affective and cognitive domains appear to play a significant role in teaching-learning dynamics. In this study we seek to assess whether the affective posture towards school sciences of a cohort of teachers in rural communities shows an association with their cognitive competence in the disciplines. The results of this study provide evidence that there is a statistically significant correlation between the cognitive and affective domains for in-service teachers. The affective domain, therefore, could serve as a predictor for cognitive competency and self-efficacy expectancies with respect to both content and career fulfilment.

Published: June 2019

Lead (Pb) is a toxic environmental heavy metal that induces serious clinical defect on all organs with the nervous system being the primary target. Curcumin is the main active constituent of turmeric rhizome (Curcuma longa) with strong antioxidant and anti-inflammatory properties. This study is aimed at evaluating the therapeutic potentials of curcumin on Pb-induced neurotoxicity. Thirty six male Sprague Dawley rats were randomly assigned into five (5) groups with 12 rats in the control (normal saline) and 6 rats for the lead treated group (LTG) (50 mg/kg lead acetate for 4 weeks), recovery group (RC) (50 mg/kg lead acetate for 4 weeks), treatment group 1 (Cur100) (50 mg/kg lead acetate for 4 weeks, followed by 100 mg/kg curcumin for 4 weeks) and treatment group 2 (Cur200) (50 mg/kg lead acetate for 4 weeks, followed by 200 mg/kg curcumin for 4 weeks) groups each. All experimental groups received the oral treatments through orogastric-tube on alternate days. Motor function was assessed using horizontal bar method while Pb concentration in the cerebellum of the rats were evaluated using ICP-MS techniques. Pb-administered rats showed significant decrease in motor scores, SOD activity with increase MDA levels and Pb concentration in their cerebellum with marked alterations in the histological architecture of the cerebellar cortex layers. However, treatment with curcumin improved the motor score, reduced Pb concentration in the cerebellum and ameliorates the markers of oxidative stress as well as restored the histological architecture of the cerebellum. The results this in study suggested that curcumin attenuates Pb-induced neurotoxicity via inhibition of oxidative stress and chelating activity.
Opacity Corrections for Resonance Silver Lines in Nano-Material Laser-Induced Plasma
Authors: EL Sherbini Ashraf M. , EL Sherbini Tharwat M. , Parigger Christian G.
Published: June 2019

Q-switched laser radiation at wavelengths of 355 nm, 532 nm, and 1064 nm from a Nd: YAG laser was used to generate plasma in laboratory air at the target surface made of compressed nano-silver particles of size 95 ± 10 nm. The emitted resonance spectra from the neutral silver at wavelengths of 327.9 nm and 338.2 nm indicate existence of self-reversal in addition to plasma self-absorption. Both lines were identified in emission spectra at different laser irradiation wavelengths with characteristic dips at the un-shifted central wavelengths. These dips are usually associated with self-reversal. Under similar conditions, plasmas at the corresponding bulk silver target were generated. The recorded emission spectra were compared to those obtained from the nano-material target. The comparisons confirm existence of self-reversal of resonance lines that emerge from plasmas produced at nano-material targets. This work suggests a method for recovery of the spectral line shapes and discusses practical examples. In addition, subsidiary calibration efforts that utilize the Balmer series Hα-line reveal that other Ag I lines at 827.35 nm and 768.7 nm are optically thin under variety of experimental conditions and are well-suited as reference lines for measurement of the laser plasma electron density.

Authors: Baños Carlos , Hernández María , Rico Antonio M. , Olcina Jorge
Published: June 2019

Tourism, and particularly residential tourism, has led to a change in the urban and demographic model of towns along the European Mediterranean coastline. Water as a limited and limiting resource for the growth of tourism is a popular topic in the scientific literature. However, the incorporation of non-conventional resources (desalination) has meant, in theory, that this limitation has been overcome. The aims of this paper are: a) to identify the different tourism models implanted in this territory and describe them from the point of view of their consumption of water in the demand cycle from 2002 to 2017; b) analyse the hydrosocial cycle, highlighting the measures aimed at satisfying water demand; and c) identify the limitations associated with these hydrosocial systems. To this end, different types of information will be processed, and various complex indicators produced. The results show the importance that demand management and the use of desalinated water in increasing the resilience of this territory to aridity. However, this has generated other problems associated with a tsunami of construction and the continuity of a non-sustainable territorial model.

Published: June 2019

Non-targeted effects (NTE) such as bystander effects or genomic instability have been known for many years but their significance for radiotherapy or medical diagnostic radiology are far from clear. Central to the issue are reported differences in response of normal and tumour tissues to signals from directly irradiated cells. This review will discuss possible mechanisms and implications of these different responses and will then discuss possible new therapeutic avenues suggested by the analysis. Finally, the importance of NTE for diagnostic radiology and nuclear medicine which stems from the dominance of NTE in the low dose region of the dose response curve will be presented. Areas such as second cancer induction and microenvironment plasticity will be discussed.

STUDI EKONOMI SYARIAH TENTANG PERUBAHAN PP NO 46 TAHUN 2013 KE PP NO 23 TAHUN 2018
Authors: Mawadah Sokhikhatul
Published: June 2019

 

Micro, Small and Medium Enterprises (MSMEs) are one of the drivers of the Indonesian economy. The MSME sector is proven to be able to survive in the midst of the economic crisis in Indonesia. At present, the growth of MSMEs from year to year continues to increase. The more rapid development of MSMEs in Indonesia will cause more contribution to the receipt of the country's Gross Domestic Product. This is where MSMEs become a sector that will have a large potential in the amount of tax revenue. The tax incentive policy for MSMEs previously regulated in Government Regulation Number 46 of 2013 provided that the final tax rate imposed on MSMEs is 1 percent of gross income. However, at present, the regulation has been amended and replaced with Government Regulation Number 23 of 2018, where the final tax rate for MSME players is only 0.5 percent of gross income. If viewed from a sharia economic perspective, a decrease in taxes is a form of government justice for MSME actors, because basically businesses run by MSMEs do not always bring profits, so that a high tax rate can burden them. This is in accordance with the general goal of implementing the economic system, namely to realize prosperity and peace for the entire community. This study aims to provide a critical review of how much the effect of changes in PP on final income tax rates for MSMEs is seen from the literature review involving several Islamic elements. The methodology in this study is qualitative descriptive. Discussion refers to previous research and results from literature studies.

Prospectif elementary students must take the test read,write,and numeracy to enter elementary school. Whereas learning in Kindergarden (TK) calistung only introduction. Kindergarden education program is more emphasized on the activity of playing as well a character building. The fact is, many kindergarden even play groups, especially in big cities have taught calistung and have a target to know calistung after they come out. This raises a polemic regarding calistung for early childhood.
Model Pembelajaran dalam Mengembangkan Multiple Intelligences Pada Anak Usia Dini
Authors: Amalia Rizka
Published: June 2019

Learning method can be interpreted as a way used to implement the plan that has been prepared in the form of real and practical activities to achieve learning objectives. There are several learning methods that can be used to implement learning strategies. Learning model has a broader meaning than the strategy, method or procedure of learning.

Multiple intelligences differentiates intelligence into specific 'modalities', rather than seeing intelligence as dominated by a single general ability. Howard Gardner proposed this model in his 1983 book Frames of Mind: The Theory of Multiple Intelligences. According to Gardner, an intelligence must fulfill eight criteria: potential for brain isolation by brain damage, place in evolutionary history, presence of core operations, susceptibility to encoding (symbolic expression), a distinct developmental progression, the existence of savants, prodigies and other exceptional people, and support from experimental psychology and psychometric findings.
EDUTAINMENT DALAM PENGEMBANGAN MULTIPLE INTELLIGENCES TEORI HOWARD GARDNER PADA ANAK USIA DINI

Published: June 2019

There are nine intelligences proposed by Howard Gardner. Nine intelligences include: intelligence language, logical-mathematical, visual-spatial, bodily-kinesthetic, rhythmic-musical, intrapersonal, interpersonal, naturalistic and existential. When speaking of the intelligence then of course it's going to talk about a person's brain. In theory the brain, it is said that the brain will only absorb information if the brain is in a state of happy to get it. Then to condition it, teachers should make learning fun and humanizing learners. Appropriate learning models would improve intelligence learners. One model of learning that can be used to improve the intelligence of the learner is to use the model of edutainment. This article attempts to provide edutainment strategies in the use of the model to the increase of multiple intelligences of children.

Published: June 2019

The development of new methods and high-bit instruments for measuring phase shifts of high-frequency periodic signals with high speed for radar and radionavigation tasks is an actual task. The purpose of this work is to create a new phase shift meter for high-frequency periodic signals based on the double-matching method using direct digital frequency synthesis.

On the basis of the proposed mathematical model of phase shift measurements of periodic signals by the method of double coincidence using the statistical accumulation of pulse coincidences, a functional diagram of a digital phase shift meter of periodic signals using a direct digital frequency synthesizer is developed. This allowed the implementation of an 8-bit converter phase shift signal to the code on the programmed logic integrated circuit EPM240T100C5N firm Altera.

The digital phase shift meter of periodic signals based on the double-matching method consists of two comparators, two short-wave pulse generators, a direct digital frequency synthesizer, two pulse counter control circuits, two short pulse coincidence circuits, two pulse counting circuits, four clock counters, four registers, a microcontroller and an indicator. Block diagram of a double-matching digital phase meter using direct digital sintesizer use minimal hardware logic.

In the developed phase shift meter, due to the use of the double-matching method, the time delay between signals does not depend on the period of input signals and can be found when changing the frequency of periodic pulses in wide limits. Measurement errors will be determined mainly by the duration of the pulses of coincidence. The use of statistical accumulation of pulse coincidence in the basis of the work allowed eliminating the restrictions on the duration of pulses of known non-ionic meters.

On the basis of the obtained results, a high-bit converter of phase shifts of high-frequency periodic signals into a binary code with high speed for problems of industrial tomography, radar and radionavigation can be developed.

In rolling fatigue tests the approach of the axes is usually measured once per cycle or for several loading cycles because of the difficulties of processing a large amount of data in multi-cycle testing. The aim of this work was the development and tests of smoothing model for measured by the SZ-01 center time series experimental data using wavelet transform.

With the help of the SZ center, the frictional moment in the roller/shaft system was measured allowing for studying the change in the coefficient of rolling resistance as a function of the level of the contact and non-contact bending load during wear-fatigue tests. Also the axes approach of the contacting bodies (roller and shaft) was measured at eight points on the raceway circumference in one cycle. This allowed studying the heterogeneity of local damages under conditions of rolling and mechano-rolling fatigue. When developing a software module for smoothing a large amount of experimental data from the test center, various methods of time series smoothing were used: moving average; exponential moving average; wavelet transform and moving average applied to the differences of the wavelet coefficients; wavelet transform and exponential moving average applied to the difference of the wavelet coefficients.

The results of numerical simulation showed that the best approximation to the original series was provided by the wavelet transform using an exponential moving average to smooth the differences between the coefficients of the wavelet transform.

The use of a software module based on this model in SZ-01 center allowed smoothing the time series characterizing the change of roller and shaft axes approach and torque.

Aging is associated with the development of various chronic diseases, in which both hypertension and osteoarthritis (OA) are dominant. Currently, there is no effective treatment for OA, whereas hypertension is often treated using L-type voltage-operated calcium channel (VOCC) blocking drugs, nifedipine being among the most classical ones. Although nifedipine together with other VOCC inhibitors plays an important role in people wellbeing, there are unresolved questions on its possible effect on cartilage tissue homeostasis and the development of OA. Due to that, the aim of this study was to analyse the effects of nifedipine on metabolic processes in human chondrocytes and bone marrow mesenchymal stem cells (BMMSCs). To analyze whether those events were mediated specifically through VOCC, agonist BayK8644 was used. Our results demonstrate that nifedipine downregulated chondrocyte proliferation rate as well as mitochondrial respiration and ATP production (Agilent Seahorse) in both cell types. Analysis of cartilage explant histological sections by electron microscopy also suggested that part of mitochondria lose their activity in response to nifedipine.However, switch of energetic metabolic pathway towards glycolytic was observed only in chondrocytes. Stimulation with either nifedipine or BayK8644 resulted in elevated production of collagen type II and proteoglycans in micromass cultures under chondrogenic condition, although the effects of VOCC inhibitor Bay8466 were less expressed. Nitric oxide (NO) activity, as measured by flow cytometry, was upregulated by nifedipine in BMMSCs and particularly chondrocytes, suggesting that NO at least in part may account for the effects of nifedipine on metabolism in both tested cell types.Taken together, we conclude that antihypertensive drug nifedipine inhibits mitochondrial respiration in both chondrocytes and BMMSCs and that these effects may be associated with increased NO accumulation and pro-inflammatory activity. Glycolytic capacity was enhanced only in chondrocytes, suggesting that these cells have the capacity to switch from oxidative phosphorylation to glycolysis and alter their metabolic activity in response to VOCC inhibition. Finally, nifedipine stimulated production of collagen type II and proteoglycans in both cell types, implying its potentially beneficial anabolic effects on articular cartilage. These results highlight a potential link between consumption of antihypertensive drugs and cartilage health

Background

Hospitals deliver 24-hour, 7-day care on a 5-day workweek model, as fewer resources are available on weekends. In prior studies, poorer outcome with weekend admission or surgery was observed. The purpose of this study was to investigate if 7-day service at a hospital affects the likelihood of the “weekend effect” in surgery. The 7-day service included outpatient consultations, diagnostic examinations, and elective surgeries.

Methods

This was a retrospective cohort study of patients who underwent surgery between April 2014 and October 2016 at an academic medical centre in Tokyo, Japan. The main outcome measure was thirty-day in-hospital mortality from the index surgery. The characteristics of the participants were compared using the Mann–Whitney U test or the chi-squared test as appropriate. Logistic regression was used to test for differences in the mortality rate between the two groups, and propensity score adjustments were made.

Results

A total of 7442 surgeries were identified, of which, 1386 (19%) took place on the weekend. Of the 947 emergency surgeries, 25% (235) were performed on the weekend. The mortality following emergency weekday surgery was 21‰ (15/712), compared with 55‰ (13/235) following weekend surgery. Of the 6495 elective surgeries, 18% (1151) were performed on the weekend. The mortality following elective weekday surgery was 2.3‰ (12/5344), compared with 0.87‰ (1/1151) following weekend surgery. After adjustment, weekend surgeries were associated with an increased risk of death, especially in the emergency setting (emergency odds ratio: 2.7, 95% confidence interval: 1.2–6.5 vs. elective odds ratio: 0.4, 95% confidence interval: 0.05–3.2).

Conclusions

Patients undergoing surgery on weekends had higher 30-day mortality than did those undergoing surgery on weekdays, especially in the emergency setting. These findings have potential implications for health administrators and policy makers who may try to restructure the hospital workweek or consider weekend elective surgery.

Background: Renal carcinoma (RCC) is widely accepted as a malignant tumor of urinary system. Long intergenic non-coding RNA 1939 (LINC01939) is a novel lncRNA which was found to be down-regulated in RCC. Thus, we set out to explore the effect and regulation mechanism of LINC01939 in RCC.
Methods: LINC01939 and miR-154 in RCC tissues and cell lines were detected using qRT-PCR assay. Cell counting kit-8 (CCK-8) assays was exploited to examine cell viability. Flow cytometric analysis was conducted to examine apoptosis. Cell mobility was valued through wound healing assays. Western blotting was applied for examination of proteins related to proliferation, apoptosis, migration and Wnt/β-catenin/Notch.
Results: LINC01939 was down-regulated in RCC tissues. LINC01939 overexpression impeded proliferation and migration, and induced apoptosis. Further study found that the overexpression of LINC01939 strongly suppressed miR-154 expression. Then, the inhibiting effect of overexpressed LINC01939 on proliferation and mobility and the promoting role of LINC01939 in apoptosis were abolished by the combination of miR-154 mimic. Finally, we found that the overexpressed LINC01939 inactivated Wnt/β-catenin and Notch through suppressing miR-154.
Conclusion: The up-regulation of LINC01939 inhibited proliferation and migration of RCC cells by down-regulating miR-154.
