Mid Infrared Spectroscopy and Multivariate Analysis Evaluation of Adulteration in Whey Protein Powder
Authors: De Carvalho dos Anjos Virgilio
Published: March 2020

Mid infrared (MIR) spectroscopy was combined with multivariate approaches Principal Component Analysis (PCA) and Partial Least Squares (PLS) regression to assess modifications in spectral profile of whey protein concentrate (WPC) powder due to changes in formulation level using caffeine, creatine and lactose, simulating fraud. Adulterations were made by replacing WPC in different levels from 5 to 50% (w/w - 5% steps) with three adulterants in separate. The spectra comparison of the samples allowed the identification of peaks associated to characteristic chemical bonds of each adulterant. PCA was carried out and 89% of the total variability of the spectral data was explained by three principal components, which allowed the confirmation of variables influencing each sample mixture and validating the spectral observations. Above 20% decrease in WPC content (20% adulteration), it was possible to differentiate all the three substances used. Predictions of percentage of WPC substitution were made through PLS regressions. The best prediction models were: lactose > creatine > caffeine. However, predictions resulted in overall good accuracy, low relative errors and coefficients of determination of fitting of calibration and validation curves above 0.97 in all cases. Therefore, techniques employed here aid the quality assessment of food products as alternative analytical tools.
Recherches expérimentales sur les phénomènes de triboluminescence et de cristalloluminescence
Authors: Longchambon Henri
Published: March 2020

En résumé, le spectre de la lumière émise dans 18 cas distincts de triboluminescence et 1 cas de cristalloluminescence a été photographié.

De l'examen de ces spectres, et des autres observations que j'ai pu faire on peut tirer les conclusions suivantes :

1° Le phénomène de triboluminescence est dû à une effluve électrique se produisant dans la fracture à laquelle on a donné naissance, et excitant la luminescence du gaz qui s'y trouve.

2° Avec les corps fluorescents ou phosphorescents ce phénomène peut être compliqué par un phénomène secondaire de fluorescence ou de phosphorescence excité par cette effluve.

Avec les corps très durs ce phénomène peut être compliqué d'un phénomène lumineux d'ordre calorifique, le travail d'arrachement pouvant porter des particules du corps à une température suffisante pour qu'elles soient lumineuses. Il se peut que dans certains cas, seuls ces phénomènes de phosphorescence ou d'émission thermique soient en jeu.

3° Sous réserve de ces phénomènes secondaires, les atomes constituant le corps que l'on brise n'émettent pas de lumière en quantité qui ait permis de la déceler.

4° Pour la plupart des corps, l'effluve de rupture se produit au sein d'une atmosphère gazeuse fournie par le cristal lui-même. Le phénomène est entièrement indépendant du milieu extérieur au cristal.

5° Pour certains corps le phénomène dépend du milieu extérieur, et l'effluve se produit vraisemblablement aux dépens de l'atmosphère entourant le cristal.

6° Un certain nombre de cas de cristalloluminescence peuvent se ramener à un phénomène de triboluminescence, la rupture des cristaux accompagnant une variation de température.

7° Dans les autres cas de cristalloluminescence le phénomène est distinct du phénomène de triboluminescence.

8° Le phénomène fondamental de triboluminescence, consistant en une effluve électrique, ne se produit ni avec les quelques corps simples cristallisés qui ont été étudiés à ce point de vue, ni avec les corps amorphes.

9° En général ce phénomène ne se produit pas si l'on brise un cristal suivant un plan de clivage, à moins que la direction de celui-ci ne soit perpendiculaire à un axe de pyroélectricité.

10° L'effluve électrique de rupture se produit aussi bien avec des cristaux dont le réseau admet un centre de symétrie qu'avec les cristaux piezo ou pyroélectriques. On peut considérer que ce phénomène est lié au mode de répartition des atomes suivant les différents plans réticulaires, et qu'il apparaît lorsqu'on sépare deux plans réticulaires chargés d'atomes de nature différente ou liés de façon différente aux atomes sous-jacents.

11° Ce phénomène est un argument en faveur de l'hypothèse de la nature électrique des forces de cohésion entre atomes ou molécules, tant pour les composés organiques que pour les corps minéraux
MATHEMATIC MODEL OF AND METHOD FOR SOLVING THE DIRICHLET HEAT-EXCHANGE PROBLEM FOR ONE-SHEET ROTARY HYPERBOLOID
Authors: Berdnyk Mykhailo
Published: March 2020

It is the first generalized 3D mathematical model developed for calculating temperature fields in the thin-wall one-sheet rotary hyperboloid, which rotates with constant angular velocity around the axis OZ, ; the model was created with the help of known equations of generating lines in cylindrical coordinate system with taking into account finite velocity of heat conductivity and in the form of the Dirichlet boundary problem for the hyperbolic equation of heat conduction under condition that heat-conduction properties of the body were constant, and no internal sources of the heat were available. At initial moment of time, the body temperature was constant; values of temperature on outside surfaces of the body were known and presented continuous function of coordinate.The hyperbolic heat-conductivity equation was derived from the generalized energy transfer equation for the moving element of continuous medium with taking into account finiteness of the heat conductivity velocity.In order to solve the boundary problem, the desired temperature field was represented as a complex Fourier series. The obtained boundary problems for the Fourier coefficients were found with the help of Laplace integral transformations and the new integral transformation for two-dimensional finite space. Intrinsic values and intrinsic functions for the integral transformation kernel were found by method of finite element and the Galerkin methods. Besides, the domain was divided into simplex element.As a result, the temperature field in the thin-wall one-sheet rotary hyperboloid was found in the form of convergent series in Fourier functions.

Authors: Gnilenko Alexey
Published: March 2020

The full adder is a key element of any arithmetic logic units used in microprocessor systems. For microprocessor components created for modern mobile digital devices, compact layout design on the silicone chip is of great importance. In this paper an area effective layout design on the chip is proposed for 4-bit ripple carry adder based on pass transistor logic. The full adder is simulated using EDA tool and output signal waveforms are obtained to demonstrate the functionality of the design. It is shown that 1-bit full adder based on pass transistor logic and composed of two 3T XOR gates and one 2T multiplexer allows us to obtain area effective layout design on the chip for 4-bit ripple carry adder providing acceptable characteristics for output signals.

THERMODYNAMIC LAWS OF CHROMIUM REDUCTION BY MIXTURES OF СН4 + Н2О AND СН4 + СО2
Authors: Gryshyn Oleksandr , Nadtochij Angela , Velykonska Nataliia , Zykin Yevhenii
Published: March 2020

The development of a physico-chemical model of methane behavior in the processes of solid-phase reduction of chromium-containing raw materials will allow us to create the technological basis for the production of multicomponent sponge ligatures. The reduction of oxides with methane is accompanied by the deposition of soot carbon. The negative effect of carbon black, which is blocking the reaction surface, can be eliminated by adding carbon dioxide or water vapor to methane. A thermodynamic analysis of the reduction of chromium oxide with mixtures of CH4-CO2, CH4-H2O was carried out. The effect of the partial replacement of methane by carbon on the thermodynamic preferences of the process is analyzed. A physicochemical model of the behavior of the CH4 molecule in the recovery process is proposed. The thermodynamic features of reduction at various ratios of СН4 are considered: (Н2О, СО2, О2), as well as the composition of the mixture (Н2О+СО2+О2), which ensure the conditions of solid-phase reduction of oxides and the product of carbide destruction. The use of CH4 + H2O + O2 mixtures in the reduction of chromium oxide is thermodynamically less effective. The use of a mixture of СН4 + Н2О + СО2 has a very insignificant effect on the conversion of methane, and also reduces the thermodynamic preference for the reduction of Cr2O3 in comparison with СН4 + Н2О + О2 and СН4 + Н2О. However, it should be noted that in addition to CO and H2, carbon can be present in the reduction products, so the high reduction potential in this process variant (C+CO+H2) can be used to reduce oxides. The reduction of chromium oxide with mixtures of СН4 + Н2О + О2, СН4 + Н2О, and СН4 + Н2О + СО2 can be thermodynamically realized in the temperature range excluding the melting of the charge. As a result of this process, a carbide phase is formed, as well as a gas phase, which has a high reduction potential and can be used in further technological schemes. Meanwhile, it seems possible to control the carbon content in the sponge ligature by selecting the optimal composition of the source gas mixture.
METALS HEAT TREATMENT MODEL

Published: March 2020

This paper considers the problem of developing a model of thermal metal processing by multiprocessor computing systems. The obtained metal is used for high-strength fasteners manufactured by cold forging method without final heat treatment. The model is based on the heat treatment method of a billet from low- and medium-carbon steels intended for cold heading. The model aims at improving technological properties of a billet by ensuring high dispersion and uniformity of a billet structure across the entire plane of its cross-section.Implementation of the proposed model ensures the technical result of high dispersion and uniformity of the structure of the billet. The technological process of steel heat treatment is characterized by high performance, low power consumption, and improved performance characteristics. The apparatus for implementation of the spheroidization annealing regime determines the uniform distribution of cementite globules in the ferrite matrix, which means that it provides the necessary mechanical properties of the metal for its further cold deformation. The multiprocessor computing system software allows controlling the temperature conditions, both on the entire plane of the billet section, and across its length. Such temperature conditions are controlled in the center of the plane of the billet cross-section.Experimental studies of the heat treatment of metal products were conducted. In order to test the functions of the proposed model, several experiments were performed when a 20 mm diameter wire from 20G2G steel was subjected to heat treatment. Experimental studies have shown that metal has the necessary elasticity properties, saving the required hardness.
BURDEN MATERIAL DISCHARGE FROM THE ISOLATION BELL OF THE BLAST FURNACE CHARGING AREA
Authors: Selegei Andrey , Ivaschenko Valery , Golovko Vyacheslav , Mikhailovsky Nikolay , Selegey Svetlana , Mirgorodskaya Alexandra
Published: March 2020

Blast furnace practice has been remaining the most suitable one in the steel production route. A rather large amount of blast furnaces (BF) is equipped with bell-like charging equipment. The discharge capability of such equipment has a drastic influence on the parameters of the charging operations and blast furnace driving rates. The charging features regulate in many cases burden materials descend and the parameters of the BF smelt. In relation to the mentioned, it is revealed that to determine the volume of the burden materials flow passing through the isolation bell of the BF charging area is an urgent scientific and engineering problem. A number of publications is devoted to the problem how to define the burden materials flow coming from the large bell. Most of these studies are grounded on the expressions by prof. Zenkov. However, there is a drawback apparently present in these findings and it can be expressed as the lack of the complex approach to incorporate such parameters as the material type, its granulometry and the geometry of the isolation bell outlet hole. The aim of the current research is to reveal the analytic dependence capable of determining the volumetric flow of the burden materials passing through the hole of the large bell. Thus, possessing the data on the burden materials flow and the geometry of the isolation bell outlet hole, one can determine the initial conditions for developing the trajectory of burden materials movement within the top area of the blast furnace. Moreover, the method proposed with the current publication permits determining the actual aggregate size of the burden materials coming to the BF top charge through the data of burden materials volumetric flow. Further, the actual size of the material particles being charged can be derived from the dependences presented in this work and this, in its turn, influences the permeability of the burden materials column for gases at a given point of BF top radius. Taking these data into account, the real opportunity emerges for an on-line correction of the BF drive by incorporating the certain on-line conditions of BF smelt. The results of the findings reported in this article are to be utilized for improvements on the automation system of blast furnace charge control.
Застосування методів рухомого керування для стабілізації космічного апарату з аеромагнітною системою відведення
Authors: Lapkhanov Erik
Published: March 2020

В роботі проведено дослідження застосування методів рухомого керування для здійснення грубої стабілізації космічного апарату (КА) з аеромагнітною системою відведення (АМСВ). В свою чергу, АМСВ складається з двох підмодулів: аеродинамічного плоского вітрильного елементу і електромагнітних виконавчих органів. Електромагнітні виконавчі органи слугують для здійснення орієнтації і стабілізації аеродинамічного плоского вітрильного елементу перпендикулярно до динамічного потоку атмосфери, що набігає. Встановлено, що забезпечення такої стабілізації для плоских вітрильних аеродинамічних елементів збільшує силу аеродинамічного гальмування на 40-50 % і зменшує час відведення на 25-30 %. Однак, для ефективного функціонування таких систем, головним критерієм є мінімізація витрат бортової електричної енергії в довготривалих космічних місіях з відведення відпрацьованих КА з робочих орбіт. Виходячи з цього, було запропоновано застосування методів рухомого керування для електромагнітних виконавчих органів (магнетторків) за допомогою яких здійснюється груба стабілізація аеродинамічного елементу. Встановлено, що при застосуванні методів рухомого керування витрати бортової енергії можна на порядок зменшити.

Квадратичные оптимизационные модели и методы
Authors: Kosolap Anatolii
Published: March 2020

Фактически в любой сфере человеческой деятельности при проектировании сложных систем необходимо выбирать наилучшие решения. Это позволяет экономить ресурсы, время, деньги. Для построения математических моделей систем разработан инструментарий. Наиболее простыми являются линейные модели с непрерывными переменными число которых может быть достаточно большим. Разработаны эффективные методы, позволяющие находить оптимальные значения переменных в линейных моделях. Однако класс задач, которые можно описать линейными моделями, очень ограничен. Большинство проектируемых систем являются нелинейными. Для таких систем строятся нелинейные модели и используются методы решения нелинейных оптимизационных задач. Попытка аппроксимации нелинейных систем линейными в многомерном евклидовом пространстве является неэффективной. В большинстве случаев, сложные системы могут быть описаны квадратичными моделями. Если квадратичные модели сводятся к минимизации выпуклой функции на выпуклом множестве, то существуют эффективные методы для решения таких классов задач [1]. Однако систем с выпуклыми квадратичными моделями очень мало. В тоже время, общими квадратичными функциями можно описать значительное число сложных систем.

Some possible options for the formulation of inverse problems are considered. The ultimate research goals in these cases determine the algorithms for the approximate solution of the inverse problem and allow one to correctly interpret these solutions. Two main statements of inverse problems considered: inverse problems of synthesis and inverse problems of measurement. It is shown that in inverse synthesis problems one should not take into account the error of the mathematical model. In addition, it is possible in these cases to synthesize approximate solution algorithms that do not have a regularizing property. Examples of practical problems considered.

This paper addresses the problem of creating mathematical methods to optimize time and computing resources when processing Big Data. These methods are based on the proposed data organizational structure called “m-tuples based on ordered sets of arbitrary cardinality”. We formulated certain properties of the given data organizational structure as a consequence of the logical rules applied for the formation of m-tuples. A set of functional dependencies was also derived between m-tuples based on their location in the structure. A graphical interpretation was presented to illustrate the change of dynamics in fractions of operand combinations for which one tuple is a subset of the other. It takes into account the variation in the lengths of operand tuples. We also obtained logical conclusions about the influence of the properties studied and mathematical methods of working with the given structure to minimize the computing resources involved.

Published: March 2020

This paper purpose is to construct maximally parallel algorithms for solving economy problems that are described by dynamic models. The problems of mathematical modeling of a similar class of problems on parallel cluster-type computing systems are considered. Most conventional algorithms for solving such problems (methods of runs, decomposition of a matrix into two diagonal matrices, doubling, etc.), with several processors, usually work no faster than with a single processor. This is caused by significant computations’ sequence of such algorithms. The developed procedure of numerical and analytical sampling is quite simply generalized to other types of differential equations of mathematical physics. In particular, in stationary problems it is easier to localize features and apply high-order schemes in the smoothness areas.

Published: March 2020

This article discusses the change in the magnitude of the currents of cathodic protection stations with changing seasons. The change in the value of currents at a constant voltage of the stations is significant. The work draws attention to the fact that with excess current, wasteful use of resources is possible. Given that changes in electrical parameters are possible not only with changing seasons, but also under the influence of precipitation, groundwater level, technological factors, it is advisable to automatically control the cathodic protection station. The use of joint control by several cathodic protection stations is proposed, which will minimize their combined influence. Coordination of the operating modes of the stations is minimizes the wasteful use of resource.

The method of sequential approximation (MSA) [1] allows representation of a reproduced function in an analytical form in the form of a product of functions, each of which depends on one variable. The paper is devoted to application of the representation of a function in the vicinity of a point and is considered for evaluation of numerical filter parameters. The result of this representation is an analytical expression in the form of a product of independent functions of one variable. As the practical experience of technical applications shows, the function of the parameters is quite satisfactorily describes its behavior throughout the definition area. An example of the application of this approach to the solution of an important scientific problem of numerical filter parameters determination is proposed.

Authors: Verney Caroline , Few Janet
Published: March 2020

This paper describes a small part of wider research into family and community in the nineteenth century undertaken by the late Caroline Verney. Her study of the north Devon parishes of Bittadon, Braunton, Georgeham, Marwood, Mortehoe and West Down centred on the way in which Victorian farming communities functioned, with investigations into kinship stemming from that core theme. At the same time, Janet Few was researching the role of kinship and its impact on community cohesion in three other areas of north Devon: Bulkworthy, Bucks Mills and Hatherleigh. Few's work on the farming parish of Bulkworthy is particularly relevant and has been used to complement Verney's findings for Mortehoe, which form the focus of this article. Together they have been used to investigate the employment of farm servants and the basis upon which they might have been chosen.

O presente artigo traz uma reflexão teórica realizada por meio de análise de três obras produzidas pelo artista francês Jean-Baptiste Debret durante o período em que esteve no Brasil, no início do século XIX. As obras selecionadas foram analisadas com base na teoria e conceitos propostos pelo historiador da arte Michael Baxandall. Assim, o objetivo foi destacar obras de Debret que representassem cenas de gênero mostrando momentos de ócio e lazer para, a partir delas, aplicar a metodologia de observação de obras de arte proposta por Baxandall. O método empregado foi de abordagem qualitativa com enfoque indutivo na análise dos dados coletados, bem como a pesquisa é bibliográfica e empreendida pelo uso de fontes secundárias. Por fim, considerou-se que as obras de Debret retratam muito mais do que cenas de gênero, sendo também testemunhos históricos no tocante a hábitos e costumes marcantes de uma sociedade de época.

Published: March 2020

O presente estudo de natureza descritivo-exploratória buscou analisar se a descentralização top-down do Programa Segundo Tempo (PST) via terceiro setor garantiu a diminuição das desigualdades regionais e entre os municípios por níveis de desenvolvimento humano. Utilizou-se dos dados do Ministério do Esporte referentes às adesões do terceiro setor ao PST (convênios firmados e executados) de 2003 a 2011. A amostragem do estudo foi constituída de 412 cidades. Políticas de equidade, que são a finalidade última da participação do governo federal na descentralização de programas, não são alcançadas sem uma estratégia eficiente de alocação dos recursos nas regiões e localidades mais vulneráveis. Longe da disputa sobre universalização e focalização, a Constituição Federal de 1988 imprimiu uma funcionalidade do governo federal no sistema federalista. E, sob esse aspecto, os incentivos do programa à participação do terceiro setor demonstraram ser inadequados.

O transporte público oportuniza o acesso às experiências e aos espaços de lazer, nos centros urbanos para as comunidades periféricas, democratizando os bens culturais da/na cidade. Nesse sentido, o objetivo deste trabalho é analisar o ciclo político da “Tarifa Domingueira”, da cidade de Curitiba-Paraná, que incentivava o uso do transporte público para o lazer. Utilizou-se da pesquisa documental, para efetuar a investigação e análise da Domingueira, da implantação à extinção do programa. Conclui-se que o ciclo político foi regido pelos interesses das diferentes gestões, atores políticos, instituições público-privadas diretamente ligadas ao sistema de transporte e à gestão da cidade, porém, pouca intervenção de grupos sociais organizados. Assim, faz-se necessário fomentar a participação da sociedade civil nos ciclos políticos para fomentar a participação democrática na política e o acesso aos bens culturais.
Usabilidade de Sites e Gestão da Informação na Análise e Divulgação dos Programas de Recreação em Sites de Resorts no Brasil

Published: March 2020

Esse estudo qualitativo teve por objetivos analisar os sites de resorts, com base na gestão da informação e na usabilidade de sites, bem como, investigar a divulgação dos programas de recreação. Por meio de pesquisa exploratória foram elencados os sites, os quais foram avaliados com base nas Teorias da Gestão da Informação e da Usabilidade de sites, criando-se categorias a priori, para análise dos dados. Os resultados indicam que as informações acerca do programa de atividades recreativas oferecidas são precárias e pouco motivam a adesão à prática. Além disso, os sites dos resorts não atendem a todos os critérios de usabilidade, dificultando a busca por informações pelo usuário, podendo gerar aos estabelecimentos o comprometimento das vendas, devido a essas falhas existentes nos sites. Sugerem-se novos estudos relacionando as temáticas envolvendo tecnologias, turismo, recreação e lazer.
O Lazer como Afirmação da Identidade no Timing da Finitude
Authors: Monteiro Claudia Franco , Brito Cristiane Miryam Drumond de , Borges Raquel de Magalhães
Published: March 2020

Este trabalho é fruto de uma pesquisa do Programa de Pós-Graduação em Estudos do lazer e visa apresentar sua fundamentação teórica para um campo etnográfico referente a pessoas no timing da finitude da vida. Para tanto, apresenta as contribuições de importantes pensadores sobre o tema morte e atividade cotidiana/habituais como afirmação da identidade tais como Morin, Giddens e Kellehear. Propõe uma reflexão sobre o lazer dentro da perspectiva da filosofia existencial e investiga a possibilidade do lazer ser manifesto com um forte sentido de identidade e alinhado aos desejos mais autênticos no tempo da finitude. Mas também busca avançar para reflexões sobre o ser morrente, como um sujeito social e passível de interferências do mercado de consumo e da cultura de massa nas escolhas de atividades de lazer, além de outros determinantes como a condição sociocultural.

Swallowing Difficulties with Tracheostomy: A Neuro-Rehabilitation Perspective
Authors: Saqulain Ghulam , Mumtaz Nazia
Published: March 2020

Swallowing and breathing are complex and highly coordinated functions. These functions depend on well-coordinated work of many organs with larynx and nervous system playing a critical role. Disturbance in one of these functions negatively affects the other. Surgical airways like tracheostomies are required in a number of situations, including but not limited to major head and neck procedures, cases with decreased lung function, excessive bronchial secretions and cases requiring neuro-rehabilitation when prolonged airway is required for mechanical ventilation. Extensive neuro-rehabilitation is required since patients with surgical airway may develop swallowing difficulties including dysphagia and/or aspiration with a very high prevalence, which can pose a threat to life. This article reviews the current status of the diagnostic and therapeutic modalities for swallowing difficulties with special emphasis on current neuro-rehabilitative strategies. Electronic databases including Medline, Web-of-science, Cochrane Library, and Google scholar were used for literature search. Downloaded articles were subsequently assessed independently by two researchers to determine suitability for inclusion in the study.Key words: Neurorehabilitation, Tracheostomy, Transcranial direct current stimulation, Transcranial magnetic stimulation, swallowing difficulty

Background: Coronary artery disease (CAD) is associated with the highest mortality in women around the world. The objective of this study was to compare the clinical risk factors and angiographic pattern of coronary artery disease in young versus old age females having CAD.Material and Methods: This cross-sectional study was conducted at the Department of Cardiology, Chaudhry Pervaiz Elahi (CPE) Institute of Cardiology Multan, Pakistan from April 2018 to December 2018. All females with diagnosis of angina and consistent ischemic changes on ECG were enrolled in the study. A total of 230 females were included with 123 patients aged <45 years and 107 patients aged >45 years. Comparison of patient characteristics, clinical risk factors and angiographic pattern in young and old age females was done by using SPSS version 21 statistical software.Results: Prevalence of hypertension (P=0.001), dyslipidemia (P=0.06) and diabetes mellitus (P=0.007) was significantly higher in females of older age group (>45 years). Similarly, a larger number of older age females (32; 29.9%) presented with ST-Elevation Myocardial Infarction (STEMI) as compared to young female patients (22; 17.88%) (P=0.03). Regarding angiographic patterns of CAD, there was no difference in the prevalence of single vessel disease (SVD), double vessel disease (DVD) and triple vessel disease (TVD) between the groups. Normal angiogram was found in 13 (12.3%) old age females versus 35 (28.8%) young females, respectively (P=0.002).Conclusions: The risk factors profile and clinical presentation of CAD is different in young female patients with CAD. There is an essential need to determine the coronary atherosclerosis factors in young females and these women should be treated more aggressively to prevent adverse cardio-vascular outcomes.Key words: Angiographic Pattern, Coronary Artery Disease, Clinical Pattern, Young Females

Authors: Sanmarco Jéssica , Marcos Verónica , Seijo Dolores , Novo Mercedes
Published: March 2020

Se diseñó un estudio de archivo para conocer las tasas de multi-publicación de los investigadores españoles de Psicología en revistas de prestigio. Para ello, se calculó el promedio de artículos publicados por autor y año natural en revistas indexadas en la Core Collection de la Web of Science por 551 investigadores, clasificados por área de conocimiento. Los resultados mostraron que el 5% de los investigadores tenían una producción atípica (valores outliers o extremos) y, por el contrario, otro 5% no tenía producción científica. La autoría probable de artículos por autor oscila, según área de conocimiento, entre alrededor de 1 artículo por año (límite inferior del intervalo) y en torno a 2 y 2,5 (límite superior del intervalo) por año, publicando la mitad de la distribución (mediana) más de un artículo al año. El límite superior del intervalo de normalidad establece que el 5% de los investigadores publican en promedio, según área de conocimiento, ligeramente más de 2 ó 3 artículos al año. Además, los resultados pusieron de manifiesto diferencias significativas en la tasa de multi-publicación entre las áreas de conocimiento, registrándose en el área de Personalidad, Evaluación y Tratamiento Psicológico la mayor tasa de multi-publicación por autor. Se discuten las implicaciones para la evaluación de la actividad investigadora del profesorado de Psicología.

In this world, that it would be a school, office, banks or apartment the only thing which we concern is safety and security. In this case, we are trying to keep our personal belongings safe like data, money and other important files to be secured from unauthorized persons. To overcome this technology, we are going to represent a fingerprint and algorithm-based security system that provides complete security and making unable to access for unauthorized person or someone else. Therefore, in this system, we are going to tighten the security for the unauthorized person. In this system, we are going to authorize the person's fingerprint who is going to open the locker or door. This fingerprint recognition is only done by the Arduino Uno to check for authentication. In this case, if the person has the correct fingerprint matched with the registered fingerprint, the door will automatically open otherwise the GSM module will be triggered and the registered person will get the concern alert message and the buzzer connected will be intimate the sound to alert the surroundings officially. Here we have done a few algorithms for more safety purposes.
