Can We Map Culture?
Authors: Underwood Ted , So Richard Jean
Published: June 2021

Images that convert culture into physical space have a durable appeal, and numbers make it possible to literalize a spatial representation of culture by measuring the “distances” between cultural artifacts. But do cultural relationships really behave like physical distance? There are good reasons to think the analogy is imperfect, and a number of alternative geometries have been proposed—extending, in a few cases, to a systematic distinction between the mathematics of “embodied experience” and “epistemic experience” (Chang and DeDeo 2020). We test several proposed alternatives to spatial metrics against ground truth implicit in human behavior. While it is sometimes possible to improve on distance metrics, we do not yet find evidence that the information-theoretical measures recommended as appropriate for epistemic questions are generally preferable in the cultural domain.

Authors: Tuğba Kartal Ayşe , Çağla Mutlu Zeynep
Published: June 2021

The aim of the present study was to evaluate the relationship between febrile convulsion, serum iron levels and whole blood parameters. This cross-sectional case-control study included patients aged 6 months-6 years-old brought to the department of pediatrics of Kütahya ParkHayat Hospital with febrile convulsions between January 2015 and December 2019. The patients were divided into two groups as: febrile with convulsions (study group; n= 47) and febrile without convulsions (control group; n= 35). Both groups were age and sex-matched. Some blood parameters such as mean serum iron, ferritin, Hb and MCV levels were used to compare the groups. Mean serum iron levels of the study and control groups were 33.7 ± 2.1 μg/dL and 56.3 ± 7.4 μg/dL (p<0.05), and serum ferritin levels were 27.3 ± 6.2 ng/mL and 31.1 ± 2.1 ng/ mL (p>0.05), respectively. Mean hemoglobin levels of the study and control groups were 10.6 ± 1.7 g/dL and 11.1 ± 1.4 g/dL (p <0.05), and mean MCV levels were 71.1 ± 1.2 fL and 73.2 ± 1.1 fL (p>0.05), respectively. In the light of the findings of this study, the low serum iron and ferritin levels may be reinforcing factors for developing febrile convulsion. However, multicentre studies with more patients are needed to reach a precise conclusion.

Published: June 2021

The aim of this study was to compare the influence of a final rinse with and without passive ultrasonic irrigation (PUI), using 17% ethylenediaminetetraacetic acid (EDTA) or 10% citric acid (CA), with 2.5% sodium hypochlorite (NaOCl) with PUI, on the sealing ability of root canal fillings. Root canal instrumentation was performed in single-rooted premolars using NaOCl as the irrigant. Subsequently, the roots were randomly allocated into four experimental groups (n=23): EDTA+PUI, EDTA, CA+PUI, CA and control group: NaOCl+PUI. The specimens were root-filled using gutta-percha with a resin-based sealer and inserted into a device to measure glucose leakage at 7 and 30 days. Kruskal-Wallis and Mann- Whitney tests were used to evaluate the differences between the solutions and with or without PUI. Friedman’s ANOVA was used to compare time points (P<0.05). PUI groups showed lower infiltration values (EDTA+PUI 0.74±0.77 and CA+PUI 5.32±1.45) when compared to the groups on which PUI was not performed (EDTA 7.20±2.18 and CA 20.73±4.70), this difference was significant for EDTA (P<0.01) and CA (P=0.000). Also, EDTA showed less glucose infiltration than CA, with or without PUI (P<0.005). NaOCl+PUI showed a higher cumulative glucose infiltration (22.92±9.71). A final rinse using EDTA or CA with PUI enhances the sealing of root canal fillings. EDTA showed less infiltration.

Authors: Rubín De Celis-Quintana Gisela Nataly , Moreno-Rodríguez Adriana , Torres-Rosas Rafael , Argueta-Figueroa Liliana
Published: June 2021

Las bacterias arginolíticas metabolizan la arginina que se encuentra en la saliva produciendo amoníaco, el cual potencialmente es un factor endógeno de inhibición de la microbiota cariogénica. Las pastas dentales con arginina podrían brindar mayor disponibilidad de dicho compuesto y, por tanto, ayudar a la prevención de caries. El propósito de esta revisión fue evaluar la evidencia publicada acerca del efecto anticariogénico de pastas dentales que con-tienen arginina. Se realizó una revisión sistemática de literatura, en las bases de datos PubMed, Scholar Google y Web of Science, publicada en el período 2010 a 2020. Los criterios de elegibilidad fueron artículos originales con diseño de ensayos clínicos aleatorizados y observacionales, en texto completo en inglés o español, con participantes de todas las edades, en los cuales se hubiera evaluado el efecto anticariogénico de la arginina. De los 424 registros identificados, se revisaron 42 artículos en texto completo. De éstos, siete estudios se seleccionaron por cumplir los criterios de elegibilidad. En tres estudios se observó una disminución en el incremento de procesos cariosos, dos estudios determinaron que la actividad del sistema arginina deiminasa es mayor, la remineralización de lesiones incipientes en esmalte lo reportan dos estudios, así como la reducción en la producción de ácido láctico. No se reportaron efectos secundarios relacionados con la arginina. Con base en el análisis de los estudios incluidos, se concluye que los dentífricos que contienen una combinación de fluoruro y arginina, poseen una mayor cantidad de beneficios y actividad anticariogénica cuando se comparan con dentífricos convencionales.
Design and Fabrication of Rocker Bogie Mechanism
Authors: Tamgadge Mayank
Published: June 2021

The rocker-bogie suspension mechanism its currently NASAs one of the favourite design for wheeled mobile robots, mainly because it has multipurpose capabilities to deal with different types of surface and obstacles because it uniformly distributes the overall weight over its 6 wheels at all times. That's why it has many advantages when dealing with obstacles, there is one of the disadvantage is its low average speed of operation, the rocker bogie system generally not suitable for situations where high-speed operations for which to cover large surfaces Areas. mainly due to stability problems. Our purpose is to increase the stability of the rocker-bogie mechanism system by expanding its support design structure, making it more stable and flexible while moving at high speed, at different surfaces but keeping its original flexibility against obstacles. Most of the flexibility of this method can be achieved without any mechanical modification to existing designs only a change in control strategy. Some mechanical changes are required to Achieve the maximum Advantages and to increase the rover operations speed in future. We will develop a method of driving a rocker-bogie vehicle so that it can effectively step over most obstacles rather than impacting and climbing over them. The Rocker-Bogie Mechanism system was designed to be used at slow speeds. It is capable of overcoming obstacles that are depends upon the size of a wheel.
Replacement of Sand by Quarry Dust in Concrete
Authors: Borsare Suraj V
Published: June 2021

The role of quarry dust in the construction of building and other structures to eliminate the demand of nature sand by using quarry waste to replace the use of natural sand. We are investigating the potential of using quarry waste and its effect on the strength and workability of concrete. Initially cement concrete cube was studied with various proportion of cement concrete +quarry dust (M20 & M25). The experimental result showed that the additional of quarry dust as fine aggregate ratio of 30%, 40% and 50% was found to enhance the compressive properties. The compressive strength of concrete cubes at the age of 7 and 28 days were obtained at room temperature. These raw materials of concrete, i.e., river sand and gravel, are also struggling to cope with the rapidly growing demand in many areas around the globe. The sources of good quality river sand and gravel are depleting very fast. According to United Nations Environment Program (UNEP) report, “Sand-rarer than one thinks”, published in March2014, sand and gravel has now become the most widely used natural resource on the planet after water. These are now being extracted at a rate far greater than their renewal. Crushed sands, fine aggregate produced from stone crushing, has become very popular in areas where natural sand is not abundantly available or where there is scarcity in the supply of natural sand. The Mumbai-Pune express highway was a project, where there is a difficulty in procurement of natural sand. This made the construction company to use crushed sand for making approximately 20 lakh cum of concrete necessary for the construction. However, such type of sands contains a large amount of micro-fines, i.e., particles finer than 75 microns, which can have an adverse effect on properties of concrete. So proportioning of different raw materials at the time of mix design is very important, when crushed sand is used in concrete The availability of sand at low cost as a fine aggregate in concrete is not suitable and that is the reason to search for an alternative material. Quarry dust satisfies the reason behind the alternative material as a substitute for sand at very low costIt is found that 40% replacement of fine aggregate by quarry dust gives maximum result in strength than normal concrete and then decreases from 50%. The compressive strength is quantified for varying percentage and grades of concrete by replacement of sand with quarry dust.

Journal bearings typically consists of metal sleeve that fits around a shaft. The sleeve is held in place within a housing. The journal is simply place on the shaft that is surrounded and supported by the bearing. Journal bearings can be made out of metallic or non-metallic materials such as bronze, aluminium etc. Bearings are generally made out of material that is softer than the metal of the shaft. Typically, journal bearings are used in various applications such as turbines, compressors, centrifugal pumps etc. The performance of hydrodynamic journal bearing is depend upon the lubrication. Lubrication provides a thin film between internal sliding surfaces of the bearing components to reduce friction. Nowadays crude oil uses increases day by day. Due to depletion of petroleum resources, increasing its price and environmental pollution interest is developed towards the use of economical, environment-friendly lubricants. Bio-lubricants are made from vegetable oils. They are environment-friendly, non-toxic and also having performance benefits such as high viscosity index, high lubricity, high load carrying capacities, rapid biodegradability etc. In this review paper, to improve performance of hydrodynamic journal bearing and also to replace petroleum oil different types of bio-lubricants were examined.

A Review of High Performance Solar Stills for Desalination of Waste Water
Authors: Kagdelwar Abhishek S.
Published: June 2021

Pure water is renewable resource on the earth, it getting impure now a days. Solar desalination is one of the best way to produce fresh water from any type of impure water in a sustainable way. A solar still is a simply design device used to purify the water by using solar energy by the process of evaporation and condensation. Generally, the productivity of the conventional solar still is about 1–5 L/m2/day. But this quantity is not sufficient for an individual to fulfill daily needs of water in life. Hence either more than 1 L/m2 is required per person or better for modifications to improve the solar still design for the demand of the fresh water (likely more than 5 L/m2/day). In this work, an attempt has been made to categorize the different solar still designs with productivity more than 5L/m2/day. Here, we identify as such efficient high productivity of solar stills and discuss their modifications and heat transfer mechanism to reach at useful conclusions. This review will be a reference guide for future researchers who wish to concentrate only on efficient high productivity of solar stills to improve the productivity or efficiency.

In the busy metropolitan cities like Hyderabad, Mumbai, Delhi, people don't have time to invest in waiting for transport. Waiting time for transport in such crowded cities leads to less productivity on a whole. People face this problem in their daily life where they have no idea about the current status of their transport. So, the proposed solution is an android based application that will help the user to check out the current location of the bus and also will help the user to know how much time the bus will take to reach the current location of the user. The system will use GPS as the basis for the application and basic android application will be interfacing with the updated database to provide the real-time data to the user, hence enhancing the user-experience.
High Temperature, High Cycle Fatigue Demeanor of 10wt% cr Steel and Unlike Metal Weld
Authors: Shah Hilal Ahmad
Published: June 2021

The present study primarily focuses on understanding the high cycle fatigue behavior (HCF) of alloy 10wt%Cr Ferritic Steel and Dissimilar metal weld (DMW) joint between 617M and 10wt%Cr Ferritic Steel. For assessing the HCF behavior, tests were conducted under stress controlled cycling, by employing dissimilar stress ratios (R) and wide range of temperatures (300 K – 853 K). The S-N curves plotted at R= -1 and temperatures (300 K,673 K,853 K) for 10wt%Cr Ferritic Steel shows that fatigue life decreased with increase in stress amplitude. It is also observed that fatigue life of 10wt%Cr Ferritic Steel falls with increase in the temperature regardless of the stress amplitude, clearly showing the strong dependence of fatigue life on the temperature. An effort has been made to find out the fatigue parameters at 300 K and 853 K using Basquin equation. These fatigue parameters were used for life prediction, showed that predicted life is in good agreement with experimental life with in a scatter band of 2. At 853 K, Goodman diagram shows that limiting alternating stress decreases with increase in the mean stress. The results were linked with the detailed scanning electron microscope investigation where it is analyzed that at 300 K, the fatigue failure was by trans-granular mode, characterized by striations while at 673 K and 853 K, intergranular mode and strong oxidation is seen, thus lowering the life at said temperatures. The standard S-N behavior for DMW at R= -1 and at temperature of 853 K showed that the welding reduces the number of cycles to failure. Vicker’s hardness measurements show that there is softening in the 10wt%Cr side & hardening in the butter layer resulting in failure of all non-defective samples on the 10wt%Cr side. HCF test was also showed on damaged samples at 230 MPa and 200 MPa, found, that crack initiates & propagates near the damage at 230 MPa while at 200MPa crack initiates and propagates in the 10wt%Cr side irrespective of the damage.

In cyber world everything is dependent on data and all Artificial Intelligence algorithms discover knowledge from past data only, With the development of information technologies, the trend of integrating cyber, physical and social (CPS) systems to a highly unified information society, rather than just a digital Internet, is becoming increasing obvious. An increasing amount of personal data, including location information, web-searching behaviour, user calls, user preference, is being silently collected by the built-in sensors inside the products from those big companies, which brings in huge risk on privacy leakage of data owners. In this paper, we aim at securing data by combining blockchain and AI together, and design a Secure Networking architecture (termed as SecNet) to significantly improve the security of data sharing, and then the security of the whole network. In SecNet, to protect data, one of the biggest challenges is where and how to store data, because users have to give their data to service providers if they want to use certain services or applications.

Published: June 2021

El sector de la construcción es un pilar fundamental para la economía y el desarrollo del país. En años recientes, este ha tenido un crecimiento a gran escala, pero también ha sido uno de los sectores donde se generan más residuos sólidos, tanto ordinarios como de construcción y demolición, los cuales son dispuestos en botaderos a cielo abierto o en escombreras, con una gestión deficiente, provocando diversos problemas a la comunidad cercana y al medio ambiente. El aprovechamiento de residuos sólidos aplicados a proyectos constructivos ha sido considerado como una alternativa de sostenibilidad ambiental; por lo anterior, en esta investigación se implementaron residuos de construcción y demolición, botellas de tereftalato de polietileno (PET, por sus siglas en inglés), tierra, guadua, residuos madereros, restos de alambre y envolturas plásticas en la construcción de galpones como alternativa de mejora en comunidades rurales afectadas por la violencia en Antioquia, específicamente en el corregimiento El Prodigio del municipio de San Luis. Como resultados se determinó que la implementación de materiales alternativos en la construcción de galpones permitió la integración social y la reducción del deterioro ambiental debido al uso de 1864 kg de materias primas residuales consideradas para la comunidad como desechos, y 279 kg de materiales no residuales, donde un elemento natural como la guadua ocupó el mayor valor porcentual con 95 %, y el 5 % restante, correspondiente a materiales propios del sector de la construcción. Por lo tanto, la aplicación de la sostenibilidad dirigida al campo avícola promueve el uso de materiales alternativos en lugares donde es necesario su aprovechamiento como mejora ambiental y social; es por lo anterior que en esta investigación surge como objetivo general minimizar los residuos plásticos presentes en la parte urbana y rural de la zona de estudio.

On the evaluation of both spatial and temporal performance of distributed hydrological models
Authors: Nguyen Tam , TRAN AN , Uniyal Bhumika , Phan Thuc
Published: June 2021

Evaluating the spatial and temporal model performance of distributed
hydrological models is necessary to ensure that the simulated spatial
and temporal patterns are meaningful. In recent years, spatial and
temporal remote sensing data have been increasingly used for model
performance evaluation. Previous studies, however, have focused on
either the temporal or spatial model performance evaluation. In
addition, temporal (or spatial) model performance evaluation is often
done in a spatially (or temporally) lumped approach. Here, we evaluated
(1) the temporal model performance evaluation in a spatially distributed
approach (spatiotemporal) and (2) the spatial model performance in a
temporally distributed approach (temporospatial) model performance
evaluation. This study demonstrated that both spatiotemporal and
temporospatial model performance evaluations are necessary since they
provide different aspects of the model performance. For example,
spatiotemporal model performance evaluation helps in detecting the areas
with an issue in the simulated temporal patterns. However,
temporospatial model performance evaluation helps in detecting the time
with an issue in the simulated spatial patterns. The results also show
that an increase in the spatiotemporal model performance will not
necessarily lead to an increase in the temporospatial model performance
and vice versa, depending on the evaluation statistics. Overall, this
study has highlighted the necessity of a joint spatiotemporal and
temporospatial model performance evaluation to understand/improve
spatial and temporal model behavior/performance.
Hospitalization For Iron Deficiency Anemia In Young Children: A Multicenter Analysis
Authors: Segal Julia , Mack Molly , McCormick Meghan , Kalpatthi Ram
Published: June 2021

Background Iron deficiency anemia (IDA) is detrimental to growth and
neurodevelopmental outcomes in young children. IDA is primarily managed
in the outpatient setting, though children with severe anemia may
require admission. No prior studies of children with severe IDA admitted
to US children’s hospitals exist. The objective is to describe
characteristics of children requiring admission for IDA. Procedure Using
the Pediatric Health Information system database, we identified children
age 0-5 years admitted from 2004-2018 with a primary diagnosis of IDA.
Patient characteristics were compared by chi-square test or t-test of
means. Univariate logistic regression was used to identify factors
associated with readmission. We also performed a retrospective review of
primary care records. Results A total of 4963 unique patients were
identified, with 5202 unique hospitalizations. The mean age at admission
at index hospitalization was 1.5 years with no gender difference. A
trend towards an increasing number of admissions was noted in recent
years. The majority of the patients received blood transfusions (87.3%)
and oral iron (61.4%), whereas only 4.9% of patients received
intravenous iron. Overall, 13.1% of patients required ICU admission,
which was more common in female patients and children of Black or Asian
race. Factors associated with decreased odds of readmission included
blood product transfusion and use of oral iron during the index
hospitalization. Conclusions IDA is a preventable condition, with
potential for detrimental long-term outcomes. Trends in the number of
admissions over time are concerning in light of the substantial use of
hospital resources.
