Authors: Matynia Elżbieta
Published: January 2021

The Lost Treasure of Solidarity The article discusses the political changes in Poland. The author offers information on Solidarity, a social movement between 1971 and 1981. The Solidarity miracle that disappeared with the terror of martial law imposed in December 1981 reemerged only briefly in a more limited version to hover over the spectacular Roundtable negotiations in April 1989. The surge in both the volume and the diversity of civil initiatives in the mid-1970s coincide with the signing of the Helsinki Accords and with the country's dramatically worsening economic situation.

The Origins of the Flying University and the Society of Scientific Courses Since the beginning of 1977 groups of students begun to participate in courses organized outside the official educational institutions. This was due to the censorship of official university curricula in humanities and social sciences, especially in literature, history, philosophy, sociology and economy. At the beginning the unofficial courses were organized within the network of academic ministry. The Flying University started its operation in the spring of 1977 in Krakow and in the autumn that year in Warsaw by organizing public lectures and seminars in private apartments. On January 22nd 1978 several outstanding Polish scientists signed The Founding Declaration of the Society of Scientific Courses. The main goals of the initiative – which remained unrecognized by authorities – was not only to organize and patronize independent teaching, but also to grant scholarships and to publish books in samizdat. The activities of the Society were backed by the Catholic Church, but the communist authorities tried to suppress them. The author of the paper describes the circumstances in which both the Flying University and the Society of Scientific Courses were organized.
Wojna na znużenie. NOW-a a aparat przemocy 1982–1989
Authors: Sowiński Paweł
Published: January 2021

NOW-a Publishers versus Polish Secret Service, 1982–1989 This article contributes to the history of the biggest Polish underground publishing project during the communist period. Sowinski argues that NOW-a publishers, though attacked by the police, was not destroyed. One of the main reason for this was the resilience of the grassroot activists energised by external support from Polish émigré circles in the West. Author also seeks causes of NOW-a success as underground book producer in the strategy of limited police harassment of the late stage of communist dictatorship. After martial law had been lifted in 1983 the Polish authority avoided to take major operations against opposition, i.e. massive crackdowns and imprisonments. Instead, the regime developed more subtle methods of policing the illicit book circulation. However, what constantly hampered the police effort to penetrate the NOW-a network was a lack of solid intelligence. The article offers a deep insight into the police investigation, agents reports as well as provides with fresh statistic on independent publishing and the police counterattacks.

Solidarność jako piękna pamiątka
Authors: Kuczyński Paweł
Published: January 2021

Solidarity as a beautiful memorabilia I have written this reflection as both, a social movement researcher and a Polish citizen at the same time. The text is the analysis of the uses and abuses made not only by politicians who have interpreted Polish history of the eighties, but also, by the leading trade union who defines itself as the only successor of Solidarity, while in fact, Solidarity in the eighties was not only a trade union. It was a total, three-dimensional social movement encompassing citizens, workers and independence. Thanks to this unique synthesis, there took place a great breakthrough which covered not only Poland but also the whole soviet camp. Growing amnesia forces us to put the question: who, in todays’ reality, needs a real memory of Solidarity’s input to Polish history? Answering this question it is worth to exclude political parties and their allies fighting for power. It is fascinating to observe how contemporary Polish society is changing and what are the scopes of discussion among the new political actors emerging every year. Naturally, the focus is more on the future than on the past. The heritage of Solidarity wanes gradually but still remains alive among some of social milieu composed of three different groups: the biggest one is old Solidarity militants looking behind with melancholy and bitterness, the second are young leaders of new social movements who are conscious of the historical role of Solidarity as a social movement as well as the differences between the old and new times. Last but not least we should remember about the new generation of scientists who are focused on Solidarity phenomenon. Most of them are historians rather than sociologists.
Correlational Study of Student Perceptions of their Undergraduate Laboratory Environment with respect to Gender and Major
Authors: Nyutu Eva , Cobern William W. , Pleasants Brandy A-S.
Published: January 2021

The science laboratory learning environment has been a distinctive area in science education since the 19th century. Unfortunately, students are generally not aware of what science instructors expect from laboratory experiences, and far too often, the undergraduate science laboratory curriculum lacks explicit, well-defined goals. Science instructors assume that they have created their laboratory curriculum in such a way as to reflect an ideal science instructional laboratory, but students may not recognize this. What previous studies do not indicate is the extent to which students understand the laboratory goals for instruction as intended by the instructors. This study, therefore, using a quantitative design, examined undergraduate science major (biology, chemistry, and physics) and non-major students’, and female and male perceptions of their science instructional laboratory with respect to instructors’ goals for the laboratory. Data was collected via the Student Perceptions of the College Instructional Laboratory Survey (SPCILS) at a Midwestern University in the USA. The findings suggest that, on the whole, students perceive their instructional labs much as intended by their instructors. Female and male students were just as likely to view their instructional laboratories as intended by the instructors. Moreover, the study found no differences between science majors and non-majors. This study provides baseline data for future qualitative studies about how major and gender might be impacting students’ laboratory experiences in ways beyond what was measured on this survey. Our research was done at a teaching-oriented, midsized university. It would thus be appropriate for similar investigations to be carried out at a research-oriented university.

The objective of this research is to describe how the teacher integrates technologies in blended learning and to analyze students’ perception and challenges in blended learning. The research was conducted in a private senior high school in Bandung and used a qualitative descriptive method. The data were collected through interview and questionnaire. The findings show that the teacher had already integrated technologies to run the process of teaching and learning in the new normal era as a replacement of a face to face learning due to Covid-19 pandemic. In the blended learning, the teacher integrated the variety of technologies in teaching-learning activities, namely zoom meeting and WhatsApp group chatting for the synchronous learning and she utilized google classroom, screencast o matic screen recorder, viva video editor, YouTube, and Quizizz the synchronous learning. The students perceived  blended learning positively and determined that it is it is one of the effective ways of teaching. The biggest challenge overcome by the teacher is more time needed to learn and adapt to this new situation where they must employ technology in our educational culture. For the students, the stability of internet connection also becomes major obstacle in blended learning. Apart from that, blended learning can be an option applied in the learning process in the current pandemic era.

Complementary and alternative medicine use among hypertensive patients receiving biomedical treatment: a cross-sectional survey at the LEKMA General Hospital in Accra, Ghana.
Authors: Dumfeh Magzy  F. , Ahorlu Collins S. K.
Published: January 2021

Background: Complementary and alternative medicine (CAM) use is on the increase globally and there is an increased rate of usage among hypertensive patients.
Objective: This study was designed to describe CAM use among hypertensive patients at a municipal hospital.
Methods: A cross-sectional survey of hypertensive patients at a Municipal Assembly Hospital was conducted. Respondents were made up of 209 (99 CAM users and 110 non-Cam users) selected randomly from patients attending the hypertension clinic. The pattern of CAM use, clinical profiles of respondents, and their attitudes toward CAM were examined. Descriptive statistics and the Chi Square test were used for data analysis.
Results: Out of the 209 patients interviewed, 99 (47.36%) had used at least one type of CAM mostly herbal products (72.72%, n =72).The CAM users demonstrated poorer adherence to antihypertensive medications (30.30%, n =30) as compared to non-CAM users (8.08%, n = 80). We observed a positive association between non-CAM use and medication adherence (p = 0.001). The majority (72.72%, n = 72) of the CAM users claimed to have obtained the expected effect, however,89.89% (n = 89) did not disclose their CAM use to their physician. They cited lack of inquiry by physicians as the main reason for non-disclosure.
Conclusion: A considerable proportion of hypertensive patients receiving conventional treatment at a municipal hospital also use CAM therapies. Physicians should be encouraged to inquire about the history of CAM use among their patients to be able to advise patients concerning the possible adverse reactions and drug interactions.

Modeling and Analysis for Surface roughness in Machining EN-31 steel using Response Surface Methodology
Authors: Abhang L B , Hameedullah M
Published: January 2021

This paper utilizes the regression modeling in turning process of En-31 steel using response surface methodology (RSM) with factorial design of experiments. A first-order and second-order surface roughness predicting models were developed by using the experimental data and analysis of the relationship between the cutting conditions and response (surface roughness). In the development of predictive models, cutting parameters of cutting velocity, feed rate, depth of cut, tool nose radius and concentration of lubricants were considered as model variables, surface roughness were considered as response variable. Further, the analysis of variance (ANOVA) was used to analyze the influence of process parameters and their interaction during machining. From the analysis, it is observed that feed rate is the most significant factor on the surface roughness followed by cutting speed and depth of cut at 95% confidence level. Tool nose radius and concentration of lubricants seem to be statistically less significant at 95% confidence level. Furthermore, the interaction of cutting velocity/feed rate, cutting velocity/ nose radius and depth of cut/nose radius were found to be statistically significant on the surface finish because their p-values are smaller than 5%. The predicted surface roughness values of the samples have been found to lie close to that of the experimentally observed values.

Published: January 2021

The Personal Transporter (PeT) is an electric vehicle, with easy maneuverability and compactness, which finds its application in confined areas. It is designed to transport an individual with the aid of an intelligent system. The two main wheels are driven by separate dc motors, fed by a common battery source and aided with the power electronic drives for appropriate speed control. The directional control is a electro - differential system done using the H-bridge circuit. The speed control is done with the help of microcontroller by varying the duty ratio of pulse width modulation signals given to the mosfets in the H bridge circuit. Two castor wheels are placed in order to balance the vehicle. The vehicle is further embellished with an intelligent system that directs the person to his/her destination in the best possible manner. This is done through installing receivers and transmitters in the i-PeT, as well as the places around the specified range. The application of such a system will be very helpful in various places such as airports, hospitals, shopping centers and lounges.

Authors: Rao V. Malleswara , Veerappan AR. , Michael T. Christo , Kathirvelu C.
Published: January 2021

Thickness of the mixing sphere with multi openings in the startup system is unattainable using the design codes. Obtaining the values experimentally is also quite uneconomical. Hence the analysis of sphere with openings was performed to find the allowable thickness values based on maximum stress conditions given in ASME code. The whole start-up system was modeled in CAESAR and the flexibility analysis was carried out for all the static load cases. The reaction forces and moments acting on the connecting nozzles of the sphere were obtained and given as inputs for the finite element analysis of the sphere. The mixing sphere was modeled in ANSYS and analyzed for the maximum stress that occurs for different thickness values. The analysis reveals that the maximum stresses for the given thickness values are within the allowable limit according to ASME design code. The optimum thickness of the sphere and the corresponding allowable pressure were also determined.

Authors: Ali Rashid , Ahmad Nafis
Published: January 2021

A new model for turbulent flame velocity of premixed flame in spark ignition engine for Iso-octane air mixture has been developed and validated for a wide range of engine operating parameters. The model developed is a zero dimensional thermodynamic model. The effects of engine speed (600-1160 rpm), equivalence ratio (0.7-1.1), unburnt mixture temperature (532- 650 Rankine), compression ratio (5-8) and ignition timing (5-30 degree before top dead center) have been studied in detail. The comparison between theoretical and experimental burning velocity has been made for a wide range of engine operating parameters such as compression ratio, angle of spark, equivalence ratio, flame radius, engine speed and unburnt mixture temperature. The flame velocity obtained from the present model is in good agreement with the experimental and theoretical flame velocity of Cakir. The flame velocity computed by the present model is also in good agreement with the flame velocity calculated by Malik model.

EFFECT OF BLANK RADIUS ON RADIAL STRESSES IN HYDROFORMING DEEP DRAWING PROCESS
Authors: KUMAR R.UDAY
Published: January 2021

This paper presents evaluation and effect of blank radius on radial stresses through mathematical formulations in hydroforming deep drawing process using castor oil medium. Hydraulic pressure can enhance the capabilities of the basic deep drawing process for making cups. In hydroforming deep drawing process, applying the hydraulic pressure on blank periphery in radial direction. It is obtained through the punch movement within the fluid chamber, which is provided in punch and die chambers. These two chambers are connected with the bypass path and it is provided in the die. During the process punch movement within the fluid chamber the pressure is generated in fluid and it is directed through the bypass path to blank periphery, the fluid film is created on the upper and lower surfaces of the blank and subsequently reduces frictional resistance and is to reduce tensile stresses acting on the wall of the semi drawn blank. The blank is taking at centre place in between blank holder and die surface with supporting of high pressurized viscous fluid. The radial stresses are produced in the blank in radial direction due to punch force applied on it, the shear stresses acted by viscous fluid on the both sides of blank, so apply viscosity phenomenon to this analysis. The radial stresses are determined in terms of viscosity of castor oil, blank geometry and process parameters for magnesium alloys.

Authors: GOYAL GARIMA , SINGHAL MANISH , BANSAL AJAY KUMAR
Published: January 2021

TEM (Transmission Electron Microscopy) is an important morphological characterization tool for Nanomaterials. Quite often a microscopy image gets corrupted by noise, which may arise in the process of acquiring the image, or during its transmission, or even during reproduction of the image. Removal of noise from an image is one of the most important tasks in image processing. Denoising techniques aim at reducing the statistical perturbations and recovering as well as possible the true underlying signal. Depending on the nature of the noise, such as additive or multiplicative type of noise, there are several approaches towards removing noise from an image. Image De-noising improves the quality of images acquired by optical, electro-optical or electronic microscopy. This paper compares five filters on the measures of mean of image, signal to noise ratio, peak signal to noise ratio & mean square error. In this paper four types of noise (Gaussian noise, Salt & Pepper noise, Speckle noise and Poisson noise) is used and image de-noising performed for different noise by various filters (WFDWT, BF, HMDF, FDE, DVROFT). Further results have been compared for all noises. It is observed that for Gaussian Noise WFDWT & for other noises HMDF has shown the better performance results.

Published: January 2021

This paper addresses the issue of image segmentation. Image segmentation process is the main basic process or technique used in various image processing problem domains, for example, content based image retrieval; pattern recognition; object recognition; face recognition; medical image processing; fault detection in product industries; etc. Scope of improvement exists in the following areas: Image partitioning; color based feature; texture based feature, searching mechanism for similarity; cluster formation logic; pixel connectivity criterion; intelligent decision making for clustering; processing time; etc. This paper presents the image segmentation mechanism which addresses few of the identified areas where the scope of contribution exists. Presented work basically deals with the development of the mechanism which is divided into three parts first part focuses on the color based image segmentation using k-means clustering methodology. Second part deals with region properties based segmentation. Later, deals with the boundary based segmentation. In all these three approaches, finally the Steiner tree is created to identify the class of the region. For this purpose the Euclidean distance is used. Experimental result justifies the application of the developed mechanism for the image segmentation.

El objetivo de caracterizar los desechos generados por los comedores para la gestión de su disposición ﬁnal en la Universidad Nacional “José Faustino Sánchez Carrión” de la ciudad de Huacho. El método tiene un carácter descriptivo y comparativo, diseño experimental, determinándose el efecto de dosis de compostaje, obtenido por los desechos generados de los comedores. Resultados: se evaluó las dosis en los tratamientos (M1 = 5 %, M2 = 10 %, M3 = 15 %, M4 = 20 %, M5 = 25 %, M6 = 0%, tomados los datos de evaluación de estas dosis en el cultivo de lechuga y rabanito se proceso en un diseño experimental (se procesos con la prueba de F Homogeneidad al 5 %, para determinar el efecto de dosis). Concluidos este proceso estadísticos se precisó los resultados de cada muestra y se determinó que la muestra M4 y M5 sobresalieron en sus parámetros de evaluación. En conclusiones se determinó que las muestras de M4 = 20 %, M5 = 25 % de compostaje en dosis aplicados a la lechuga y rabanito sobresalieron en el desarrollo de hoja y fruto (raíz), con lo cual se acepta la validez de la hipótesis general donde si es posible caracterizar los desechos generados por los comedores, para la gestión de su disposición ﬁnal

A partir de marzo de 2016 y como decantación de experiencias previas, se viene desarrollando desde la Escuela de Sociología de la UNJFSC un proceso de apropiación de herramientas digitales que tiene como motivación principal responder a los requerimientos de digitalización de los procesos de licenciamiento y los de la acreditación. Nuestra escuela ha venido construyendo un espacio digital que tiene por nombre “Sociología en la Red”. Provee servicios con la finalidad de: fortalecer los procesos académicos que consisten en: provisión de contenidos digitales especializados, facilitar el acceso a información de calidad de última generación, afianzar servicios para licenciamiento-acreditación y crear comunidad académica a partir de la construcción de una “identidad digital” para la Escuela. El proceso de construcción, parte de un proceso de “empoderamiento” que tiene que ver con la “apropiación” de herramientas de los ámbitos digitales como son los “sistemas de gestión de contenidos”, estas facilitan la presencia en el mundo digital a personas y grupos que son usuarios comunes de este tipo de recursos. La primera fase del trabajo, está asegurada y ha puesto por el momento a disposición de la audiencia cuatro mil objetos digitales propios de la disciplina, cuenta con presencia sólida en las redes sociales, y explora posibilidades de integrar por un lado sistemas de “referenciación” que permitan el “reúso” de los contenidos y de otro, consolidar sistemas de gestión de los datos para conocer a los usuarios y sus usos preferenciales y necesidades de la comunidad. Esta es una experiencia en curso que articula herramientas de última generación y provee servicios a una comunidad de al menos 1970 suscriptores de la especialidadPalabras Claves: Decantación de experiencias, identidad digital, sistemas de gestión de contenidos
