calculated by the authors to use a simplified methodology that takes into account the indicators of average life expectancy at birth, the weighted average monthly wages and the average monthly pension, as well as the average duration of study and literacy of the population, for each of 54 municipalities and 8 urban districts of the Republic of Bashkortostan for the period of 2007 and 2013. A comprehensive study of spatial autocorrelation in the distribution of HDI in the republic was conducted in accordance with the five-step methodology proposed by the authors. At the first stage of the study, a weighted spatial matrix of inverse distances between the administrative centers of the municipalities was calculated. This matrix defined the spatial lag structure. At the second stage, which consisted in calculating the global and local indexes of spatial auto-correlation (Moran’s and Giris), the hypothesis about the presence of spatial autocorrelation in the HDI distribution was confirmed. Under the third stage, Moran’s scatterplots were used to visualize the spatial mutual influence of the HDI for specific municipalities for 2007 and 2013. The fourth stage consisted in spatial model estimation. Two specifications were considered: spatial auto-regression (SAR) and spatial error (SEM), both permitting to identify the mutual influence in the spatial distribution of the HDI in municipalities and urban districts. Coefficients of the models were estimated by using maximum likelihood approach. The final part of the study was devoted to the interpretation of the results of spatialregression modeling. R-Studio was used as a modelling tool.

Results. It was shown that the distribution of the HDI in municipalities of the Republic of Bashkortostan is characterized by sustainable positive spatial auto-correlation. Moreover, we note an increase in dynamics of positive spatial correlation in the distribution of the HDI, which could be explained by the increasing role of urbanization and concentration of human resources in relatively large cities. There is even “a competitive struggle” going on in a number of municipalities for resources that contribute to raising the HDI. A number of municipalities form, however, a cluster of territories with a low level of human development. These areas are mainly located in the Northeast of the Republic. The estimation of spatial regression models allowed us overall to quantify the spatial auto-correlation dependencies in the distribution of human capital.

Conclusion. The obtained results of spatial dependencies in the distribution of human capital can be used both in the development of strategies for the long-term socio-economic development of municipalities and serve as a basis for strategic planning of the development of the region.
Reliability of a Smartphone Compared With an Inertial Sensor to Measure Shoulder Mobility: Cross-Sectional Study (Preprint)
Authors: Roldán-Jiménez Cristina , Martin-Martin Jaime , Cuesta-Vargas Antonio I
Published: September 2019

BACKGROUND

The shoulder is one of the joints with the greatest mobility within the human body and its evaluation is complex. An assessment can be conducted using questionnaires or functional tests, and goniometry can complement the information obtained in this assessment. However, there are now validated devices that can provide more information on the realization of movement, such as inertial sensors. The cost of these devices is usually high and they are not available to all clinicians, but there are also inertial sensors that are implemented in mobile phones which are cheaper and widely available. Results from the inertial sensors integrated into mobile devices can have the same reliability as those from dedicated sensors.

OBJECTIVE

This study aimed to validate the use of the Nexus 4 smartphone as a measuring tool for the mobility of the humerus during shoulder movement compared with a dedicated InertiaCube3 (Intersense) sensor.

METHODS

A total of 43 subjects, 27 affected by shoulder pathologies and 16 asymptomatic, participated in the study. Shoulder flexion, abduction, and scaption were measured using an InertiaCube3 and a Nexus 4 smartphone, which were attached to the participants to record the results simultaneously. The interclass correlation coefficient (ICC) was calculated based on the 3 movements performed.

RESULTS

The smartphone reliably recorded the velocity values and simultaneously recorded them alongside the inertial sensor. The ICCs of the 3 gestures and for each of the axes of movement were analyzed with a 95% CI. In the abduction movement, the devices demonstrated excellent interclass reliability for the abduction humeral movement axis (Cronbach alpha=.98). The axis of abduction of the humeral showed excellent reliability for the movements of flexion (Cronbach alpha=.93) and scaption (Cronbach alpha=.98).

CONCLUSIONS

Compared with the InertiaCube3, the Nexus 4 smartphone is a reliable and valid tool for recording the velocity produced in the shoulder.

Authors: Bogaerts Annick , Bijlholt Margriet , Mertens Lotte , Braeken Marijke , Vanden Eynde Hannelore , Jacobs Bart , Vandenberghe Bert , Ameye Lieveke , Devlieger Roland
Published: September 2019

BACKGROUND

The inter-pregnancy period is an important window of opportunity to prevent gestational weight retention. Despite an overwhelming number of existing health apps, validated applications to support a healthy lifestyle in women during both pregnancy and postpartum are lacking.

OBJECTIVE

To describe the development and evaluation of the INTER-ACT app, part of an inter-pregnancy lifestyle coaching module targeting women with previous excessive gestational weight gain.

METHODS

a mixed methods design to identify needs of healthcare providers and end users, based on 15 semi-structured interviews, two focus groups and two surveys. The user interface was evaluated in a pilot study (n=9).

RESULTS

Healthcare providers indicate that a mobile app can enhance a healthy lifestyle in pregnant women. Pregnant women preferred graphic displays in the app, weekly notifications and support messages based on their own goals. Both mothers and health care providers reported increased awareness and valued the combination of the app with face-to-face coaching.

CONCLUSIONS

We report on the development and evaluation process of an application to promote a healthy lifestyle in a specific female population. These women valued the INTER-ACT app because it was offered in combination with face-to-face contact with a caregiver.

Authors: Faizal Muh. Disna , Haryanto Aris , Tjahajati Ida
Published: September 2019

Anaplasma platys is a tick-borne, Gram-negative bacterium that causes anaplasmosis, a companion vector-borne disease impacting dogs. Information on this disease remains limited in Indonesia. Its symptoms are not specific, so molecular analysis is required for a rapid and accurate diagnosis. GroEL is an essential gene commonly used for classification and species identification of many groups of bacteria, including Anaplasma spp. In this study, a molecular diagnosis of anaplasmosis based on the groEL gene sequence was conducted using PCR. In addition, the genetic diversity of Anaplasma platys in infected dogs was determined. Blood samples were collected from 51 dogs suspected of anaplasmosis from Prof. Dr. Soeparwi Animal Hospital, animal clinics, and pet shops in the Yogyakarta area, Indonesia, based on anamnesis, histories of tick infestations, and clinical symptom examinations. DNA extraction and PCR targeting the groEL gene were performed, followed by sequencing. Phylogenetic tree analysis and construction were carried out using the BLAST and MEGA programs. Positive PCR sample results (amplicon length of 624 bp) were found in 6 of 51 dogs. Samples A1 (KHJ/C2), A2 (KHJ/A2), A3 (KSK/L), A4 (KHJ/L), and A5 (KNP/M2) had close ties to Anaplasma platys (AF478129.1) from GenBank. Phylogenetic analysis showed a very high homology value (100%) and bootstrap value of 100%. It can be concluded that there was no genetic diversity in the Anaplasma platys found in infected dogs in the Yogyakarta area.
¿Por qué tomamos tanto refresco en México? Una aproximación desde la interdisciplina
Authors: Théodore Florence L. , Blanco García Ilian , Juárez Ramírez Clara
Published: September 2019

En México, el refresco se convirtió en una bebida muy presente en la vida cotidiana y festividades, con un consumo máximo per cápita de 139.9 litros en 2012. Estos niveles de consumo, entre los más altos del mundo, dañan la salud y se asocian con obesidad y enfermedades crónicas no transmisibles como la diabetes. Beber refresco perjudica tanto la economía familiar como la del sector salud, al deber atender la emergencia de estas enfermedades, así como al medio ambiente, pues la producción de refrescos requiere extraer de manera intensa agua del subsuelo, deteriorando los mantos freáticos y su entorno. ¿Cómo se ha llegado en México a este alto nivel de consumo de refresco, convertiéndose en un problema de salud pública, al contribuir a enfermar a la población?
Inspeccionando la literatura científica de diferentes disciplinas académicas, colocaremos al centro de nuestro análisis la aproximación teórica de Sidney Mintz, que retomaremos como guía para comprender algunos de los sucesos más relevantes en el ámbito social, económico y político, desde donde se favoreció la incorporación masiva de esta bebida al escenario de la cultura alimentaria mexicana. Habremos de revisar la historia para defender nuestra argumentación: no es fortuita la ubicación de México entre los países del mundo con mayores niveles de consumo de refrescos.

Published: September 2019

Los medios de comunicación son un espacio de aprendizaje alterno que influye en la conformación de roles, modos y costumbres. A la luz de la Ley General de Derechos de niñas, niños y adolescentes en México, se establece un sistema de protección integral que contempla la suma de acciones desde diversos frentes; los medios de comunicación tienen un papel primordial. El objetivo de este artículo es reflexionar sobre la construcción de las representaciones mediáticas, como parte de un sistema de protección a los derechos de infancia. Para el análisis se establecieron criterios basados en los cuatro ejes rectores de la Convención de los Derechos del niño. Se hizo evidente la necesidad de fortalecer un nuevo escenario donde las representaciones de los medios coadyuven a la protección de derechos de infancia que marca la ley.

Climate and good performance in the construction needs to be executed, the characteristic is community participation, transparency, responsiveness and accountability. If this does not work together it will be a bottleneck in the development. With reference to the MPR IV / MPR / 2000 on recommendations in the Implementation of Regional Autonomy Policy, then the provision of opportunity for the public to actively participate in the implementation of development processes, including in the process of spatial planning. To realize the true public participation should be pursued. So cooperation with relevant parties such as universities, non-governmental organizations (NGOs), community leaders, parliamentarians, and other stakeholders need to be synergized. Strategies undertaken to improve the role of the community can be done by: 1) increasing awareness (Awareness Raising), 2) Advocacy Policy (Policy Advocacy), 3) Development Institutions (Institution Building), 4) Capacity (Capacity Building). Thus the community involvement in spatial planning becomes particularly relevant in the context of creating its territory, namely the layout in the public interest and create a beautiful environment

Published: September 2019

Plant vegetation accumulates polycyclic aromatic hydrocarbons (PAHs) among which benzo[a]pyrene (B[a]P) is recognized as being very toxic, including cancerogenic. Lymantria dispar L. larvae are sensitive to changes in the environment, providing potential signs of pollutant presence. We examined the chronic effects of two concentrations of B[a] P on the activity of carboxylesterase (CaE), acetylcholinesterase (AChE) and heat shock protein 70 (Hsp70) levels in the brain tissue of two populations of L. dispar larvae, originating from unpolluted and polluted habitats. We found that the relative growth rate was significantly lower in both populations and that only larvae from polluted forests were sensitive to low B[a]P concentrations, exhibiting a significant increase in brain tissue CaE activity and Hsp70 concentration. AChE activity showed no changes in response to B[a]P exposure in either population. Examined biochemical parameters indicate that their sensitivity to chronic treatment with B[a]P was highly dependent on the pre-exposure history of L. dispar larvae, suggesting that they could be promising biomarkers of B[a]P and PAH pollution in forest ecosystems.
Coupled simulation of a thermoelectric generator applied in diesel engine exhaust waste heat recovery
Authors: Xiao Guo-Quan , Zhang Zheng
Published: September 2019

This work develops a heat transfer model of a thermoelectric generator to explore the coupled relationship between high temperature exhaust flows, structure, and the external cooling air. The coupled heat transfer results showed that the fins reached a uniform high temperature, for the rated speed, the average temperature is 474 K. The coupled design scheme of the thermoelectric generator tested by installing it in a 4-cylinder turbocharged Diesel engine exhaust system. Comparison of the test and simulation results showed that as engine speed in-creased, the inlet and outlet exhaust temperatures of the thermoelectric generator exhibited a parabolic trend increase. The cooling water outlet temperature and the top, middle, and bottom fin temperatures increased linearly, and the coupled model was verified. From idle speed to rated speed, the top, middle, and bottom fin temperatures increased from 458 K to 476 K, 417 K to 463 K, and 406 K to 449 K, respectively; the cooling water outlet temperature increased from 293.6 K to approximately 303 K. Hence, the thermoelectric components installed in fins can experience temperature differences of over 100 K, the heat transfer efficiency can increase which ensures consistent output performance of the thermoelectric generator based on coupled design between the heat exchanger and thermoelectric modules array column.

Published: September 2019

Global warming and other climate change phenomena became a worldwide exploited subject over recent decades. World science has made enormous progress in understanding past climate change and its causes, and continues to study current and potential impacts that will affect people in the future. All scientists agree that the Earth's climate is changing due to natural phenomena, and most of them argue that human activities are increasing the greenhouse effect, while some scientists attribute climate changes exclusively to the natural causes. Though there still is, and always will be, need for multiple lines of research on an extremely complex system like Earth's climate is, an immediate consensus is crucial for decision-makers to place climate change in the context of other large challenges facing the world today. This paper discusses the existing body of evidence on climate changes in the past, and uncertainties that prevent scientists to reach full consensus on how climate might change in the future. It extends the time scale of climate changes over the entire history of Earth to help better understanding of hypothetical changes and their consequences that could be expected both in the near and in a very distant future.

Published: September 2019

This article presents the developed methodology for the numerical simulation
of radiation heat transfer from water panel heaters and optimization results
of water temperature in the supply pipeline from the mass flow rate of the
heat-carrier and the surface area for a given thermal power of the panel
system. A numerical mathematical model is developed in the assumption that
heat transfer occurs by means of radiation heat exchange by longitudinal
ribs and pipes, which are thermally insulated on top. It is assumed that the
temperature of the rib base is equal to the temperature of the outer wall of
the pipe. The irregularity of the radiation density in different directions
depends on the angle and distance to the irradiated area. The aim of the
work is to develop a methodology to simulate the heat transfer processes of
a radiation panel water heating system and optimization of design and
operating parameters. The radiation intensity is determined by a numerical
method using the MATLsoftware package. Our results of experimental
studies of the radiation flux density are presented and compared with the
results of numerical ones. The thermodynamic efficiency of a panel heating
system is analyzed using the entropy production method (exergy destruction).
The multicriteria optimization of water temperature in the supply pipeline
is performed by LP?-search. It is found that the unevenness of surface
temperature of panels reaches 24.4% as well as for the panels of about 50m
in length a decrease in water temperature to 20K is observed, which leads to
the unevenness of radiation flux density over the heated area. The area of
the cooling system as a function of water temperature and the conditions
under which the entropy production in the system is minimal is determined.
Study and analysis of the cavitating and non-cavitating jets - Part two: Parameters controlling the jet action and a new formula for cavitation number calculation

Published: September 2019

This part of the paper presents the relation between the working conditions, nozzle geometry, nozzle diameter, and jet behavior. Experimental work has been made by impinging the submerged jets on the copper specimen as a target for a period of time. The mass loss and erosion rate at various conditions were measured, calculated and analyzed. For the visualization, a high-speed camera was used and the obtained data were processed to measure parameters which are used to characterize the clouds. Correlations among the jet dynamic power, the cavity length, erosion rate, and the pertinent experimental parameters are apparent. In addition, formulas are proposed to conveniently compare the efficiency of jetting systems based on working conditions. Based on the mathematical analyses of the obtained results a new form for cavitation number calculation is proposed.

The 3-D flow of Casson nanofluid over a stretched sheet with chemical reactions, velocity slip, thermal radiation, and Brownian motion have been analyzed. By employing the similarity transformation, the ODE are obtained from the fluidic system PDE. The transformed ODE are handled for the numerical solution of the proposed fluidic problem by incorporating shooting technique. To compare the obtained numerical results, Lobatto 111A method has been implemented, with 5-8 decimal places of accuracy. The numerical data for the fluidic parameters of interest are demonstrated in the tabular form, further few proficient parameters effects like magnetic parameter, Lewis number, stretching rate parameter, the thermal radiation parameter and Prandtl number on velocity, temperature and concentration profiles have been exhibited numerically as well as graphically. By enhancing the velocity slip parameter, increment is examined in temperature and concentration profiles while opposite behavior is recorded in the velocity profile. Both the concentration and temperature profiles decline with the increase in the Stretching rate ratio parameter.

Published: September 2019

In this research the 3-D transient non-linear thermal analysis of the hard-facing process was performed by using the experimental testing and finite element method. Testing was done at three different carbon steels and the obtained results were compared to one obtained by empirical formulas and welding recommendations. Experimental testing was done on hard faced specimens (plates) with different thickness. Temperatures and temperature cycles was measured by using thermocouples in order to determine maximal temperature and cooling time between 800?C and 500?C. After experimental testing the finite element method analysis was done. The simulations were executed on the open source platform Salome using the open source finite element solver Code Aster. The Gaussian double ellipsoid was selected in order to enable greater possibilities for the calculation of the moving heat source. The numerical results were compared with available experimental and mathematical results.

OBJECTIVE

To investigate temporal trends and contemporary use of insulin pump therapy and glucose monitoring in type 1 diabetes.

RESEARCH DESIGN AND METHODS

In a population-based study, we analyzed the use of insulin pump therapy, continuous glucose monitoring (CGM), and self-monitoring of blood glucose (SMBG) from 1995 to 2017 in patients with type 1 diabetes identified from the Diabetes Prospective Follow-up (DPV) database in Germany and Austria. Patients were stratified by age, sex, migration background, and country.

RESULTS

Among 96,547 patients with type 1 diabetes (median age 17.9 years, 53% males), the percentage using insulin pump therapy increased from 1% in 1995 to 53% in 2017, with the highest rates in the youngest patients (92% in preschoolers, 74% in children, 56% in adolescents aged <15 years, 46% in adolescents aged ≥15 years, 37% in adults). The percentage of patients using CGM increased from 3% in 2006 to 38% in 2017, with the highest rates in the youngest patients (58%, 52%, 45%, 33%, and 15% of respective age-groups). Daily SMBG frequencies increased from 1995 to 2016 and decreased afterward, most prominently in the youngest patients. Between 2015 and 2017, pump therapy was more frequently used in female versus male adolescents and adults (all P < 0.001), while no sex differences were observed for pump use in children <10 years (all P = 1.0) and for CGM use in all age-groups (all P = 1.0).

CONCLUSIONS

Since 1995, insulin pump use has continuously increased, and insulin pump therapy is now standard in patients aged <15 years. CGM use sharply rose in recent years, particularly in young children.
