Water Temperature Control Using PID Control System Based on LabVIEW
Authors: Ramadhani Ari
Published: February 2020

Abstract - Automatic system have grown widespread across all sector so do water heater. Traditionally, heating water is done by utilizing fire as heat source. As the growing of technology, the heating process could be done by manipulating electrical energy by convert it to heat. Electrical energy is flown to a metal rod that contact directly with the water which increase the water temperature. On some case, appropiate water temperature is needed. Altough, a thermometer is needed to read the actual temperature as a feedback value for the system and a system that can control the electricity current flow through the heater that the heat produced is linear to the current flow. With implementing microcontroller as a process node for generating PWM signal, this problem can be solved. Also, Labview is needed as an interface for monitoring and bursting an output which have been processed by Proportional, Integral, and Devivative (PID) controller to producing accurate and stable heat. Based on the results of testing, the system is able to provide a rapid response to any changes that occur, both changes in set-point and changes in water temperature (actual value). Another test is done by comparing the temperature value detected by the temperature sensor in this device with an external digital thermometer placed in the same place, and from some of the tests the temperature value detected by the temperature sensor in this device has a difference of ± 0.19 ℃ with a digital thermometer.

Se realizaron estudios arqueométricos que involucraron la aplicación de microscopía electrónica de barrido y técnicas termoanalíticas sobre distintas piezas óseas recuperadas del sitio de Boca de Lega (BL), Provincia de Santa Fe, Argentina. El material ósteoarqueológico recuperado de BL, exhibe una baja integridad mecánica y una distribución a nivel superficial, debido a procesos de acumulación de depósitos sedimentarios, re-depósitos y erosión del ambiente fluvial. También se observó signos de posible termoalteración. Los primeros estudios arqueométricos sobre un elemento denominado como BL21, lograron determinar la existencia de accionar antrópico de sociedades pretéritas. A partir de estos resultados, se avanzó en el análisis de otros elementos óseos de BL, denominados BL07, BL26 y BL49, mediante nuevos estudios arqueométricos en donde se aplicaron técnicas analíticas como ser: análisis térmico diferencial, termogramimetría y microscopía electrónica de barrido con microanálisis dispersivo de energías. El uso conjunto de estas técnicas permitió identificar la alta incidencia de componentes edáficos en las muestras como también el registro de un calentamiento que fue superior a 673K/400°C. En virtud de los resultados obtenidos fue posible reconfirmar el muy posible accionar humano como factor originario de la termoalteración previamente observada.

Esta exposición tiene por finalidad ofrecer una síntesis sobre un tipo específico de registro arqueológico: talleres líticos. Estima que el mismo tiene una correlación estructural con el terreno y procura representarla con mapas de relieve y pendiente, otorgando a ésta última un valor de atractor causal para la explotación eco-económica del ambiente por la población prehispánica. Los talleres estudiados se localizan en el sur de la Sierra de Comechingones, en un sector de cordones serranos erosionados con altitud máxima de 1100 m.s.n.m. Se trata de un tipo de registro arqueológico muy numeroso en esta parte de la sierra; se considera al mismo representativo de un modo de producción y una larga tradición tecno-económica por parte de las poblaciones indígenas que colonizaron este paisaje en tiempos prehispánicos.
sistema ferroviario argentino en los 90’ desde una mirada socio-técnica:
Authors: Garcia Farjat Marcelo José , Novaira Nicolas , Salguero Sergio
Published: February 2020

El presente trabajo tiene como objetivo principal explorar y discutir, desde una mirada socio-técnica, el comportamiento y funcionamiento del sistema ferroviario en los 90’ en el marco de políticas privatizadoras. El ferrocarril ha tenido en la Argentina un rol preponderante dentro del desarrollo industrial al ser considerado como un elemento estructurante del territorio nacional, al facilitar la integración e interconexión territorial y por ser una fuente de trabajo relevante para vastos sectores del país. Para ello, en primer lugar, se hará una presentación y discusión acerca de los distintos grupos relevantes que formaron parte de la definición del sistema ferroviario desde el modelo constructivista SCOT, atendiendo a la reciprocidad existente entre política y tecnología de manera contextual. En segundo lugar, tomando en cuenta ciertas limitaciones de este modelo, se consideran ciertas políticas que orientan al sistema ferroviario a entenderlo como una tecnología autoritaria y de exclusión. Luego se dará cuenta que el atraso y estancamiento tecnológico en el sistema ferroviario respondió, por un lado, a la falta de políticas científicas y tecnológicas y por otro, a la estructura económica y social del país; y no por la mera falta o carencia de capital científico y tecnológico. Finalmente, se analizará el rol del Estado en la constitución de un sistema científico- tecnológico en el marco de la necesidad de un proyecto de país y de la vinculación con otros componentes relevantes tales como la infraestructura científicotecnológico y el sector productivo.

Published: February 2020

As the fifth-generation (5G) mobile communication is utilizing millimeter-wave (mmWave) frequency bands, electromagnetic field (EMF) exposure emitted from a 5G mmWave mobile handset should be evaluated and compliant with the relevant EMF exposure limits in terms of peak spatial-average incident power density. In this work, a fast power density (PD) assessment method for a 5G mmWave mobile handset using the equivalent currents (EQC) method is proposed. The EQC method utilizes the intermediate-field (IF) data collected by a spherical measurement system to reconstruct the EQCs over a reconstruction surface, and then computes the PD in close proximity of the mobile handset with acceptable accuracy. The performance of the proposed method is evaluated using a mmWave mobile handset mock-up equipped with four quasi-Yagi antennas. The assessed PD results are compared with those computed using full-wave simulations and also those measured with a planar near-field (NF) scanning system. In addition, three influencing factors related to the accuracy of the EQC method, namely, the angular resolution, the phase error, and the handset position in the IF measurements, are also analyzed. The proposed method is a good candidate for fast PD assessment of EMF exposure compliance testing in the mmWave frequency range.

Barragán oculto y reservado
Authors: Żuławska-Sobczyk Elżbieta
Published: February 2020

La obra de Luis Barragán es patrimonio nacional de México. Se podría esperar investigaciones profundas y publicaciones, tanto populares como científicas, usando avanzada tecnología para acercar al lector tanto a los proyectos como a las realizaciones del arquitecto mexicano más reconocido en el extranjero. Sin embargo, las instituciones que han heredado los derechos de autor del artista protegen tanto su herencia que hacen el acceso a su obra muy difícil, sino imposible, además de excesivamente costoso. En consecuencia no sólo la obra de Barragán no es tan conocida dentro del país como afuera de este, sino también no se puede profundizar el conocimiento sobre el desarrollo de las ideas y pensamientos que guiaban al artista. Estas fases evolucionaron de manera significativa durante su vida y valdría la pena estudiarlas de una manera más detallada. En este ensayo se intenta indicar los elementos de la evolución del pensamiento artístico de Barragán que siguen poco estudiados y las causas de esta situación.

Generalized Ramsey Numbers: Forbidding Paths with Few Colors
Authors: Krueger Robert A.
Published: February 2020

Let $f(K_n, H, q)$ be the minimum number of colors needed to edge-color $K_n$ so that every copy of $H$ is colored with at least $q$ colors. Originally posed by Erdős and Shelah when $H$ is complete, the asymptotics of this extremal function have been extensively studied when $H$ is a complete graph or a complete balanced bipartite graph. Here we investigate this function for some other $H$, and in particular we determine the asymptotic behavior of $f(K_n, P_v, q)$ for almost all values of $v$ and $q$, where $P_v$ is a path on $v$ vertices.

Oxidative stress is caused by an imbalance between the production of pro-oxidants and the capacity of a biological system of rapid detoxification of free radicals. In this paper the level of pro-oxidants and antioxidants was quantified in patients with psoriasis vulgaris. The results of this study show that the level of oxygen reactive species dramatically increases and the physiologic antioxidant mechanisms are inefficient in patients with psoriasis vulgaris. These findings re-confirm that oxidative stress has a destructive and pathogenic potential in psoriasis.

Published: February 2020

To assess the correlation between main parameters of glycemic control and cardiovascular risk scores in non-diabetic persons. Risk scores were calculated by using the University of Edinburgh Risk Calculator. Risk scores are used to estimate the probability of cardiovascular disease in individuals who have not already developed major atherosclerotic disease. We correlated the results of these scores with the parameters that describes the glycaemic profile: preprandial glicaemia, HbA1c and 1 hour and 2 h post-prandial glycaemia, determined during Oral Glucose Tolerance Test (OGTT).Both fasting glycaemia and HbA1c significantly correlated with cardiovascular risk scores calculated for a period of 10 years. The recorded post-prandial glycaemic values at 1h and 2h after glucose loading didn�t significantly correlate with calculated scores, in the study group. The observed correlations underline the importance of glycaemia in the pathogenesis of cardiovascular diseases.

The glycinergic neurotransmission system is a potential pharmacological target for pain and muscle spasm relief therapy. Planarians are attractive model organisms for neuropharmacological research, due to their simplicity and neurotransmitters shared with mammals. In this study, planarians were exposed to glycine, caffeine, midazolam and ondansetron separately and to successive associations of glycine/caffeine, glycine/midazolam and glycine/ondansetron. Effects on motility were examined by a grid crossing assay. Results showed a dose-dependent reduction of motility by glycine, partially reversed by caffeine and midazolam, but not by ondansetron. Midazolam caused an intense decrease of motility, but not significantly lower than glycine. Ondansetron-treated planarians showed decrease motility compared with controls, but not with glycine or midazolam. These results are consistent with data obtained from higher organisms, showing that planarians can be used as model organisms for glycinergic pharmacological research.

One of the solutions to reduce the production and maintenance costs of the sucker rod pumping installations is to develop automated systems for regulating and controlling their operations. The development of these automated systems requires an attentive modeling of the dynamics of the mechanism of the pumping unit, process in which the identification of the values of the parameters involved in the calculations plays an essential role. The paper presents the manner of determining the values of some parameters of the mechanism of a C-320D-256-100 pumping unit starting from the variation on a cinematic cycle of the motor torque at the crank shaft. Simulations were performed with a computer program developed by the authors, and the experimental records were processed with the program Total Well Management.

There are many steps in fabrication of dental crowns and bridges at which an error can occur, and a technician can only fabricate a quality restoration if the impression itself is of adequate quality. All dental practitioners should have the ability to evaluate the quality of dental impression before sending to the laboratory. Elastomeric silicones (polysiloxane) are the most utilised impression materials in dental practice. The present study deal with the deficiencies of silicones dental impressions sent to commercial dental laboratories for fabrication of single crowns and bridges.

In this work the Raman total half bandwidths of five free nucleic acids components (cytidine-5`- monophosphate, 2`- deoxycytidine 5`- monophosphate, 2`- deoxyguanosine-5`- monophosphate, thymidine - 5� - monophosphate disodium salt hydrate and uridine-5`- monophosphate disodium salt) have been measured, respectively. Raman scattering can be used to study the fast molecular relaxation processes of free nucleic acids components in solid phase. The dependencies of the total half bandwidths and of the corresponding global relaxation times, on functional groups and on the type of DNA and RNA constituents, are reported. In our study, the full widths at half-maximum (FWHMs) for the Raman bands of these nucleic acids components, are typically in the wavenumber range from 9 to 28 cm-1. Besides, it can be observed that the (sub)picosecond dynamics studied in this work, has a global relaxation time value smaller than 1.18 ps and larger than 0.38 ps. We have found that the band centered at 1264 cm-1 for cytidine -5`- monophosphate, the profile near 1373 cm-1 attributed to thymidine -5`- monophosphate disodium salt hydrate and the band around 1233 cm-1 attributed to uridine -5`- monophosphate disodium salt, respectively, are suitable for studying the dynamical behavior of molecular fragments in nucleic acids components. For the case of solid phase samples of nucleic acids components, we can suppose that the dominant relaxation mechanism is of the vibrational type one.

Acylhydrazinecarbothioamides (2a,b) were synthesized by addition of 2-(5H-dibenzo[a,d][7]annulen-5-yl)acetohydrazide to different isothiocyanates. The new 1,2,4-triazol-3-thioles (3a,b) were synthesized by cyclization of new 2- acylhydrazinecarbothioamides (3a,b) in basic media. Alkylation of 1,2,4-triazole-3-thiols (3a-c) with ethyl bromide gave only S-substituted derivatives (4a-c). The structures of the synthesized compounds have been established on spectral data (IR, 1H-NMR and 13C-NMR spectroscopy) and elemental analysis. The cytotoxic effect of new compounds was evaluated using two alternative models on plant and invertebrate organisms.

Published: February 2020

The behaviour of some insulating fluids in contact with copper foil and / or insulation paper under thermal stress (110�30C for 1000 hours), in a closed system (the access of atmospheric oxygen being limited), has been studied by determining the changes in viscosity and concentration of CO2 and CO. The experimental data revealed that, following the applied heat treatment, the change in viscosity of the esters-based insulating fluids (both synthetic and vegetable) is approximately 7 times lower than in the case of the investigated mineral oils. It has also been found that, following the thermal ageing, the gas content of the mineral oils is substantially higher than in the esters-based oils (8 times higher for CO2 and 4 times higher for CO, respectively). The experimental results indicate superior values for the thermal stability and compatibility with the insulation paper of ester-based insulating fluids.

Fire and burns represent the fourth cause of death in the world. Numerous options for dressings exist, but their selection should be based on several factors such as burn severity, wound location and water retention. Collagen (COLL) is the most common protein in the human body and, due to its biocompatibility, is the main component in biomaterials development. Mefenamic acid (MA) is a non-steroidal anti-inflammatory drug with analgesic properties, and carboxymethylcellulose (NaCMC) is a biocompatible and biodegradable polymer that is commonly used in biomedical field. Collagen - carboxymethylcellulose - mefenamic acid hydrogels, developed in order to be used in burn treatments were lyophilized and the corresponding spongious matrices were investigated by optical microscopy, FT-IR spectroscopy, water absorption, enzymatic degradation and drug release kinetics studies. All tests revealed proper morphological structure, favourable release patterns, convenient swelling capacity and degradation profiles, indicating the possibility of their use for medical applications.

Published: February 2020

The purpose of this work was to investigate the physicochemical properties of watermelon seeds and oil and to find out if this oil is suitable and compatible with diesel engines. The results showed that the watermelon seeds had the maximum length (9.08 mm), width (5.71mm), thickness (2.0 mm), arithmetic mean diameter (5.59 mm), geometrical mean diameter (4.69 mm), sphericity (51.6%), surface area (69.07), volume 0.17 cm3 and moisture content 5.4%. The oil was liquid at room temperature, with a density and refractive index of 0.945 and 1.4731 respectively acidity value (1.9 mgNaOH/g), free fatty acid (0.95 mgNaOH), iodine value (120 mgI2/100g), saponification value (180 mgKOH/g), antiradical activity (46%), peroxide value (7.5 mEqO2/Kg), induction period (6.2 h), fatty acid: palmitic acid (13.1%), stearic acid (9.5 %), oleic acid (15.2 %) and linoleic acid (61.3%). Straight non food vegetable oils can offer a solution to fossil fuels by a cleaner burning with minimal adaptation of the engine. A single cylinder air cooled diesel engine Ruggerini RY 50 was used to measure emissions of various blends of watermelon oil (WO) and diesel fuel (WO10D90, WO20D80, WO30D70 and WO75D25). The physic-chemical properties of the oil influence the combustion process and emissions leading to the reduction of NOX and the increase in CO, CO2 and HC.

The antiplatelet effect of clopidogrel prodrug is characterized by a wide inter-individual variability that has a significant clinical relevance. Among varios factors that are involved in the occurrence of clopidogrel resistance, the genetic polymorphisms play a key role. The aim of the present study was to investigate the impact of some risk factors for atherosclerosis on the antiplatelet effect of clopidogrel in patients with acute coronary syndrome and the possible correlation with metabolizer phenotype of patients based on CYP2C19 polymorfisms. We found a statistically significant correlation (p value [ 0.05) between smoking or dyslipidaemia and the presence of ultrarapid metabolizer phenotype for clopidogrel in our research population.

Water pollution with nutrient-based contaminants represents a special concern at national level as it may lead to the occurrence of water eutrophication affecting the properties of the water bodies. This paper presents the characterisation of nitrogen distribution in water and sediments from the Plumbuita Lake (Bucharest, Romania) and the speciation of this element in the form of ammonium, nitrite, nitrate and organic nitrogen. The results of this study prove the importance of an integrated approach regarding the quantification of nutrient content with the nutrient dynamics in the evaluation of the eutrophication phenomenon.

The objective of the present work was to obtain and evaluate the solid inclusion complexes of a-, b-cyclodextrins and hydroxypropyl-a-, hydroxypropyl-b-cyclodextrins derivatives with uracil (U) and anti-cancer agent 5-fluorouracil (5FU). The thermogravimetry (TG), differential scanning calorimetry (DSC), Fourier transform infrared spectroscopy in attenuated total reflectance mode (FTIR-ATR) and scanning electron microscopy (SEM) were used to characterize these inclusion compounds. New information on the physicochemical behavior of these solid state complexes synthesized by melting in solution was obtained. Corelating the experimental data we found that the complexation occurs for each host:guest system thus, the preparation method exhibited a real efficiency to interaction achievements. The inclusion capability and the thermal stability of the studied complexes were due to both the flexibility and the size of the cyclodextrin ring as well the stereoelectronic effect of the U or 5FU molecule. We appreciated that the complexes between U or 5FU with 2-hydroxypropyl derivatives of a- and b- CD have the largest content of guest and are the most stable. The obtained results could be useful in formulation of the pharmaceutical products and also in drug delivery.
