Published: December 2019

El objetivo de la presente investigación fue determinar la relación entre los Horarios de expendio de licores “Hora Segura” y los muertos por choques de tránsito y atropellos, homicidios y suicidios. La investigación descriptiva en base a los reportes mensuales que realiza la Municipalidad Metropolitana de Lima (LM), Perú de la base de datos del Instituto de Medicina Legal (IML) registrados del 2015 al 2017, con un análisis bivariado y riesgos relativos, caracterizando a los fallecidos por muertes violentas y su relación con sexo, edad y consumo de alcohol. Existe una disminución significativa de víctimas alcoholizadas en todas las muertes violentas excepto el suicidio de mujeres, entre el 2015 y 2017. La mayor disminución porcentual en los homicidios de alcoholizados se produjo en las mujeres, significando una reducción del feminicidio. La media de edad se desplaza en frecuencias conforme pasan los años, con excepción del suicidio en mujeres entre el año base (2015) contra el 16 y 17. Las víctimas son mayores en los alcoholizados de LM, coherente con lo publicado por el anuario estadístico de la Policía Nacional, tanto en edad como en sexo. Se concluye que la disminución de muertes violentas y los cambios en edad y sexo en LM debería ser consecuencia de la política pública y los eficaces controles policiales. La “hora segura” tiene evidencias para su aplicación en todo el país. La hora segura es una estrategia eficaz para enfrentar el feminicidio.

Published: December 2019

Effect of pressure gradient on heat transfer in turbulent boundary layer is constantly investigated during creation and improvement of heat exchange equipment for energy, aerospace, chemical and biological systems.
The paper deals with problem of steady flow and heat transfer in turbulent boundary layer with variable pressure in longitudinal direction. The mathematical model is presented and the analytical solution of heat transfer in the turbulent boundary layer problem at positive and negative pressure gradients is given. Dependences for temperature profiles and coefficient of heat transfer on flow parameters were obtained.
At negative longitudinal pressure gradient (flow acceleration) heat transfer coefficient can both increase and decrease. At beginning of acceleration zone, when laminarization effects are negligible, heat transfer coefficient increases. Then, as the flow laminarization increases, heat transfer coefficient decreases. This is caused by flow of turbulent energy transfers to accelerating flow.
In case of positive longitudinal pressure gradient, temperature profile gradient near wall decreases. It is because of decreasing velocity gradient before zone of possible boundary layer separation.

The article deals with the problem of providing the population with thermal energy. Today, it is one of the important components of the central and local authorities. Now thermal energy and the sphere of thermal energy consumption in Ukraine are in a crisis condition (up to 80% of emergency networks). As a result, it negatively affects the level of energy and national security of the country as a whole. It is shown that among the main factors influencing the situation are unsatisfactory technical condition of thermal energy objects, imperfect system of pricing, lack of necessary investment funds for modernization to fixed assets of thermal energy and housing stock. As a result, this does not allow the implementation of modern technology in this area. Therefore, the quality of the population's supply of heat is very low. The data on statistics on excessive losses in the production and transportation of heat is given. This is explained by the fact that heat losses during transportation in centralized networks reach 45…60%, while the low level of thermal insulation increases them by another 1…20%. So the consumer receives a smaller portion of the thermal energy, and if you take into account the state of the old cast iron radiators that are triggered, then you can imagine how huge the heat loss is. In connection with this now, an important task is find ways to improve the efficiency of heat networks. The article gives a literary review of recent research and publications in which the solution to this problem was initiated. It has been established that the modernization and reconstruction of heat networks requires high financial costs, and so now the authorities are working to improve the efficiency of the old heating networks.
The article analyzes one of the approaches - this is the washing of radiators. In this direction, existing methods and approaches to the cleaning of heating systems are considered, and the most basic ones are defined, which allow to effectively carry out flushing of the system without its modernization and attracting additional capital investments. As a result of the spent statistical analysis and on the basis of the existing experimental base and cleaning plants, equipment has been created that allows the washing of closed or open heating as a whole or locally. It also effectively removes dirt from the inside walls of the system. The equipment works by means of combined pneumohydropimpuls and chemical methods, as well as the main mechanisms of cavitation. The result before the use of such equipment will increase the heat transfer coefficient of the whole system and more efficiently use the energy resource, saving at the same time funds.
SLOW-UP GENERATION OF NITROGEN OXIDES BY TURNING THE PRIMARY AIR FLOW IN THE SWIRL BURNER OF THE BOILER TPP 312
Authors: Kobzar S.G. , Kovalenko G.V. , Khalatov A.A. 
Published: December 2019

The aim of the work is computer simulation of the formation of nitrogen oxides in the furnace of the boiler TPP 312 with the swirl of the primary air in the boiler burners. The organization of the vortex flow allows reducing the generation of nitrogen oxides due to the formation of a return flow, which ballasts the combustion zone by oxidation products. The limitation of this technique is the reduction of the combustion temperature which can lead to underburning.
The objective of the study is to determine the formation of nitrogen oxides based on computer simulation of the gas dynamics of the firing space of the boiler TPP 312 DTEK Ladyzhyn TES when swirling streams of air are used in the burner channels.
Efficient combustion of fuel, in particular solid, is ensured by three factors: mixing of the fuel and the oxidizing agent, residence time in the temperature zone necessary for the combustion of fuel particles and temperature. The selection of the parameter is under pressure from requirements operating in opposite directions. On the one hand, a higher temperature contributes to better fuel burning, but, on the other hand, the formation of nitrogen oxides increases at a higher temperature.
Analysis of the data on the quality of coal that comes to the station made it possible to derive the averaged characteristics of coal that were used to improve the combustion model of the software package.
Conclusions
In the presence of swirling flow, the maximum temperature is 108 K lower than in the case of a direct-flow burner, which causes a 5% reduction in the generation of nitrogen oxides. Centrifugal flows created a rarefaction zone at the burner axis and the reaction products begin to heat the fuel mixture in the burner itself. The surface area of ​​the beginning of combustion during the application of twisting reduces by 30%.
The results of the study showed that the twisting of the primary air does not lead to a significant reduction of nitrogen oxides.

Published: December 2019

The efficiency of operation of perforated trays in a cyclic mode depends on the accepted hydrodynamic modes, which determine the limits of stable operation of mass-exchange column apparatus. There are no general methods of calculating the boundaries of the hydrodynamic modes of perforated trays operate in the cyclic mode. On this basis, the authors were tasked to determine the hydrodynamic modes of operation of mass-exchange column apparatus equipped with perforated trays, the action of which occurs in the mode of controlled cycles of fluid retention on the plates and the overflow of fluid through all holes or slits. Sieve and scaly trays with arched-type scales without overflow devices were selected for study.
The aim of the work was to determine the hydrodynamic modes of operation of the sieve and scaly trays without overflow devices in a cyclic mode of retention and overflow of liquid, determination of lower and upper critical velocity of the vapor in the holes of the sieve and scaly trays, the linear velocity of the vapor in the free cross section of the mass-exchange column apparatus and the relative magnitude of the liquid splash to the upper trays. Liquid flow was monitored using a flowmeter RM, air velocity in the free section of the column was monitored using an anemometer MC-13.
It was determined that the lower critical air velocity in the bubbling holes was 5.4 m/s; linear air velocity in free column cross section was 0.25 m/s. The velocity of the air in the holes at which the fluid splashes onto the upper plates begins was 8 m/s; thus linear air velocity in free column cross section was equal to 0.7 m/s.
Hydrodynamic modes of scaly trays and corresponding values of air velocity in the free section of the column were established. In bubbling mode it was 0.5…0.9 m/s, in the transitional mode it was 0.9…1.3 m/s and in the jet mode, it was 1.3…2.0 m/s. It was determined that the lower critical air velocity in the holes of the trays, below which the drain of liquid is occurs, was 6.5…7.0 m/s. The upper critical air velocity in the holes of the trays above which the liquid splash on the upper trays is observed was 16 m/s.
The air velocity in the free cross section of the column was 1.3…1.5 m/s. the relative magnitude of the liquid splash in the mode of steady operation of scaly trays in the bubbling mode does not exceed 0.1 kg/kg of air, in the jet mode, does not exceed 0.2 kg/kg of air.
It is proved that intense overflow of liquid through bubbling holes of the perforated trays occurs at air velocities less than the lower critical. For sieve and scaly trays, this velocity should not exceed 1.5-1 m/s.
A slight spillage of liquid through the holes of the trays occurs in the range of values of air velocity in the holes of sieve trays of 1.5-5.3 m/s, in the holes of scaly trays of 1,5-6,4 m/s.

Published: December 2019

Background: Stroke and dementia are frequent comorbidities. Dementia possibly increases total costs of stroke care, especially cost of institutionalization and informal medical care. However, stroke rehabilitation costs in dementia patients are understudied. Objective: To estimate inpatient stroke rehabilitation costs for Swedish dementia patients in comparison with non-dementia patients. Methods: A longitudinal cohort study with linked data from the Swedish Dementia Register and the Swedish Stroke Register was conducted. Patients diagnosed with dementia who suffered a first ischemic stroke between 2010 and 2014 ( n = 138) were compared with non-dementia patients ( n = 935). Cost analyses were conducted from a Swedish health care perspective. The difference of rehabilitation costs between the two groups was examined via simple linear regression (before and after matching by propensity scores of dementia) and multiple linear regression. Results: Mean inpatient rehabilitation costs for dementia and non-dementia patients were SEK 103,693/$11,932 and SEK 130,057/$14,966, respectively (median SEK 92,183/$10,607 and SEK 106,365/$12,239) ( p = 0.001). Dementia patients suffered from more comorbidities and experienced lower functioning, compared to non-dementia patients. The inpatient rehabilitation cost for patients with known dementia was 0.84 times the cost in non-dementia individuals. Conclusion: Dementia diagnosis was significantly associated with lower inpatient stroke rehabilitation costs. This might be explained by physicians’ beliefs on the limited effectiveness of rehabilitation in dementia patients. Further research on cost-effectiveness of stroke rehabilitation and patients’ satisfaction with stroke rehabilitation is necessary.

Published: December 2019

Background: Drug-related problems (DRP) are common in the elderly population, especially in people living with dementia (PwD). DRP are associated with adverse outcomes that could result in increased costs. Objective: The objective of the study was to analyze the association between DRP and healthcare costs in PwD. Methods: The analysis was based on the cross-sectional data of 424 PwD. Compliance, adverse effects, and drug administration of prescribed and over-the-counter drugs taken were assessed. DRP were identified and classified by pharmacists using an adapted German version of “PIE-Doc®”. Healthcare utilization was assessed retrospectively used to calculated costs from a public payer perspective using standardized unit costs. The associations between DRP and healthcare costs were analyzed using multiple linear regression models. Results: 394 PwD (93%) had at least one DRP. An inappropriate drug choice was significantly associated with increased total costs ( b = 2,718€; CI95% 1,448–3,988) due to significantly higher costs for hospitalization ( b = 1,936€; 670–3,202) and for medications ( b = 417€; 68–765). Problems with medication dosage and drug interactions were significantly associated with higher medication costs ( b = 679€; 31–1,328; and b = 630€; 259–1,001, respectively). Conclusions: DRP could significantly lead to adverse outcomes for PwD and healthcare payers, reflected by a higher hospitalization and costs, respectively. Further research is needed to clarify on interventions and approaches efficiently avoiding DRP and on the effect on patient-reported and economic outcomes.

Background: Quantifying the contribution of cerebrovascular disease to the clinical and pathological profile of Alzheimer’s disease is challenging. Objective: We aimed to determine the influence of cerebrovascular disease, amyloid-β (Aβ), and their comorbidity on cognitive decline, hippocampal atrophy, and Aβ deposition, by evaluating data from the Australian Imaging, Biomarker and Lifestyle Study of Ageing. Methods: Two-hundred and eighteen participants underwent Aβ PET, MRI, and cognitive assessment at 18-month intervals for up to 90 months. Aβ status was determined on baseline PET. Participants were also classified as V+ on baseline MRI if they had≥1 large cortical infarcts, subcortical infarcts, or cortical cerebral microinfarcts; or white matter hyperintensity volume greater than the 90th percentile of healthy controls. Linear mixed models were conducted comparing slopes of change in cognition, hippocampal volume, and Aβ load between the four resultant groups. Results: Mean age at baseline was 74 years (range 59–96). One-hundred and fifteen participants were cognitively normal, 54 had mild cognitive impairment, and 49 had Alzheimer’s disease. Compared to the Aβ-/V- group, the Aβ+/V- and Aβ+/V+ groups showed significantly faster cognitive decline and hippocampal atrophy over 90 months. V+ status was associated with greater cognitive decline (Cohen’s d = 0.85, p < 0.001) and hippocampal atrophy ( d = 2.05, p < 0.001) in the Aβ+ group but not in the Aβ- group. V+ status was not associated with Aβ accumulation in any group. Conclusion: Comorbidity of cerebrovascular disease and Aβ was associated with cognitive decline and neurodegeneration. Cerebrovascular disease was not associated with the rate of Aβ accumulation.

Published: December 2019

Jointed goatgrass (Aegilops cylindrica Host; 2n = 4x = 28, CcCcDcDc) is a tetraploid remote relative of bread wheat (Triticum aestivum L; 2n=6x=42, AABBDD) with two genomes and 28 chromosomes. The diversity center of this species is in the Fertile Crescent and in central Asia and could also be found in many places in Iran. In this experiment, 359 accessions provided by National Plant Gene Bank of Iran (NPGBI) were used. Based on the geographical distribution, the highest distribution of A. cylindrica is found in North, West and North-West regions of Iran. The data on the distribution of A. cylindrica showed that its distribution centers in Iran are more than those reported in the previous studies. Chromosome counting showed that all A. cylindrica accessions are tetraploid (2n=4x=28). Results of factor analysis for nine morphological chromosome traits showed that karyotypic variation within accessions are related to the length of chromosomes and there is difference between the accessions for their total chromosome length, but the karyotype of different accessions are almost the same for the symmetry. Low coefficient of variation in morphological traits as well as symmetric karyotypes of A. cylindrica species observed in this study could lead us to predict that A. cylindrica could be a recently evolved species among the remote relatives of bread wheat.
