Published: September 2021

Astochastic approach based optimization technique to optimize the Hata model path loss equation is presented in this paper. In this paper, the existing Hata model equation for determining path loss in medium urban city is optimized using Least Mean Square regression method. Out of various path loss models available, Hata model was chosen due to its accuracy and reliability in an urban propagation environment. The optimization technique proposed is applied to get the optimumcoefficients of Hata propagation model equation. This stochastic approach is based on reducing the mean square difference between the measured and predicted path loss by adjusting the error coefficients of MSE through regression. The MSE obtained after optimization is significantly lower than that obtained from the existing Hata model. For better planning and implementation of mobile cellular networks there is a need for modifying the existing path loss prediction models. This optimized model can be used to improve the quality of service in 900MHz band in a medium sized urban environment.

Authors: Gaur Shrishti , Sood Neetu
Published: September 2021

In the past few decades wireless communication has been growing with leaps and bounds characterised by demand for safer, faster and enhanced communication systems. Exploiting the physical properties of communication through appropriate signalling and coding processes, the concept of Physical Layer Security (PLS) has intensified. Consequently, the pursuit for this fulfilment has led to surfacing of inevitable high data traffic and challenges with data security. For futuristic technologies like 5G and beyond, traditional technologies like Radio Frequency (RF) unaccompanied have proved to be rather inefficient and search for alternative and upgraded technologies like Visible Light Communication (VLC) has gained momentum. However, VLC technology is not sufficient in all terms and in combination with RF demonstrates superior capabilities. In this paper an attempt has been made to evaluate the importance of PLS systems and the depth and degree up to which engineers and researchers have been able to reach in attaining robustness and resilience in it as an integral aspect of RF and VLC systems.

Path loss which is one of the main issues in wireless communication system and has been studied for long time. With the tremendous increase in demand in wireless technology, this Path loss needs to be optimized. Therefore, it is very important to analyse these different propagation models in order to get some useful information out and develop a system based on it. This is done to get the optimum path loss from different models. These are useful tools which makes the designers capable of designing a wireless system with great efficiency. In pursuit of the same, this paper attempts to optimize free space propagation model and hata model using GA algorithm, and shows a comparison by putting them side by side. This paper gives an insight of comparison between free space and Hata model in wireless communication taking different propagation environments into consideration.

Published: September 2021

In this paper, we will be reviewing beam steering application using lens antenna. Various approaches are available for achieving beam steering of lens antennas for different applications and some of them will be reviewed here. In radar systems, beam steering is accomplished by switching the antenna element or changing the relative phase. Beam steering has major role for 5g due to the quasi optic layer. Beam steering can also be done by varying the refractive index. In most of these papers studies, we found out that beam steering overcomes the interference, improves gain, increases directivity and also save power. Wide angle is also achieved in lens antenna.
Emergence of Digitized Gamification as an Educational Tool and the Implications on Digital Literacy and Equity
Authors: Harris Kirsilyn C. , Redlo Jesse M.
Published: September 2021

The phenomenon of gamification has developed into a widely used educational tool over the last sixty years. In that time gamification has evolved from serious games, used to educate military personnel and medical workers, to a tool used to teach a variety of disciplines. The proliferation of gamification is particularly prevalent due to the ease of access and production of games in a digital format. Whether being used in the classroom or being used in daily life as a non-traditional learner, the common man is inundated with information and games that teach. Some games intentionally teach skills, however, even those that aren’t geared towards teaching can teach peripheral skills and values that aren’t easily taught in the classroom. Unfortunately, it is difficult to determine which games and content are going to be positive and helpful to growth and development, and which will not be. One such skill that would be invaluable to teach would be digital literacy, especially in such a digitized world. Thus the question posed here is whether gamification will be a reliable tool to teach digital literacy due to its success being implemented in other disciplines.

Published: September 2021

The gift of god that is precious is vision through which, one can see the beautiful world and enjoy. But many people throughout the world are deprived of this According to October 2017 report of World Health Organization (WHO) an estimated 253 million people live with vision impairment. 36 million are blind and 217 million have moderate to severe vision impairment. Un-operated cataract is the main reason for blindness in low income and developing countries Even in China by the end of 2017, the population over 60 will reach 241 million, accounting for 17.3 percent of the country's total population and nearly 40 million are disabled and semi disabled, according to data released by the Committee for the elderly in 201 d. So, in this case most of the visually challenged people cannot afford an expensive device to use as their supporter. So, in this paper we have proposed a cost-effective 3D intelligent Walking device. This mainly depends on the sensors because they can improve the world through diagnostics in many applications and it helps to improve performance. This device is implemented using ARM Controller, IR Sensors, Vibration Sensor, as well as GSM and GPS for location Sharing. Also a voice module is introduced along with this to give the directions through audio format. This Entered device is programmed by simple machine Learning algorithms to optimize the machine.

Published: September 2021

TFET or Tunnel Field Effect Transistor in recent times has been the center of attraction of vast number of researcher’s despite of having minute subthreshold slope and excessive Ion/Ioff ratio. It is known that TFETs are much more immune to short-channel effects and fluctuations of random dopants in comparison to their MOSFET counterparts. TFETs are actually gated p-i-n diodes having tunneling current flowing between source and channel bands. In this paper deep rooted literature review has been done scanning each and every aspects of TFET including the variations of performance with different parameters. The paper finally gives a picture on the recent progress of TFET in different aspects such as from subthreshold swing to a significantly lower leakage current and high on current .For the simulation curves Nanohub.org was used as a tool. Lastly different types of TFET in respect of doping to symmetry and also gates are compared.

Authors: Gupta Ankita , Kaur Lakhwinder , Kaur Gurmeet
Published: September 2021

Global food demand is expected to be doubled by 2050, while natural resources are continuously under threat due to unpredictable climatic changes. This challenge can be tackled by increasing the yield of the crops and by reducing abiotic stresses such as water stress. Research shows that due to water stress the morphology and the structure of plant’s canopy changes. The first step in building early water stress detection system is to extract accurate area where photosynthetic activities of the plant are occurring. In this research work, comparative analysis of seven different segmentation algorithms viz., convolution gradient-based, watershed, mean-shift, k-means, Global static thresholding, Otsu thresholding and hybrid approach (combination of Global Static thresholding with k-means) has been analyzed in order to identify the most probable area of canopy where maximum photosynthetic signals can be captured. The comparison is done in terms of IoU metric. The comparative results indicate that the most appropriate method for wheat canopy segmentation is a hybrid approach, which achieves IoU score of 59.8 and its runner up algorithm is Global Static Thresholding with an IoU score 53.8.

Squaring Technique using Vedic Mathematics
Authors: Bajaj Jasmine , Jajodia Babita
Published: September 2021

Vedic Mathematics provides an interesting approach to modern computing applications by offering an edge of time and space complexities over conventional techniques. Vedic Mathematics consists of sixteen sutras and thirteen sub-sutras, to calculate problems revolving around arithmetic, algebra, geometry, calculus and conics. These sutras are specific to the decimal number system, but this can be easily applied to binary computations. This paper presented an optimised squaring technique using Karatsuba-Ofman Algorithm, and without the use of Duplex property for reduced algorithmic complexity. This work also attempts Taylor Series approximation of basic trigonometric and inverse trigonometric series. The advantage of this proposed power series approximation technique is that it provides a lower absolute mean error difference in comparison to previously existing approximation techniques.
Pathways to the successful function and use of mid-tech household water and sanitation systems
Authors: Mattos Kaitlin , Warren John , Eichelberger Laura , Kaminsky Jessica , Linden Karl G.
Published: September 2021

Mid-tech water and sanitation infrastructure – interventions that make moderate use of resources, materials, and technology while providing improvements in health and well-being – may serve an important intermediate role for communities that cannot immediately get high-tech piped infrastructure. However, such systems must be socially appropriate, technically functional, and sustainable. We determined the combinations of technical and social conditions that contribute to the success of household, mid-tech water, sanitation, and hygiene (WASH) systems using qualitative comparative analysis (QCA). We collected data on 32 household mid-tech Portable Alternative Sanitation Systems (PASS) installed in remote, rural Alaskan communities for 1 year. We then coded qualitative and quantitative data for each household ‘case’ into fuzzy-set values for four technical conditions and four social conditions. We conducted fuzzy-set QCA analyses to determine combinations of conditions (pathways) that led to the successful function and use of PASS. We identified multiple pathways for the success of PASS units, requiring combinations of technical and social conditions. Our analysis reveals that the successful implementation of household mid-tech WASH infrastructure is complicated. We recommend that deliberate steps be taken to engage homeowners, provide appropriate training and support, determine ownership parameters, and ensure the technical sufficiency of mid-tech systems before they are deployed.
Effects of micro-flocculation pretreatment on the ultrafiltration membrane fouling caused by different dissolved organic matters in treated wastewater
Authors: Ren Lanxin , Liu Chen , Meng Ting , Sun Yingxue
Published: September 2021

This study investigated the efficacy of using micro-flocculation as a pretreatment approach in alleviating ultrafiltration (UF) membrane fouling caused by organic matter in treated wastewater. Three typical model dissolved organic matters (DOM), humic acid, fulvic acid, and sodium alginate, were employed to simulate membrane fouling. The results showed that micro-flocculation using poly aluminum chloride (PAC) or polymerized ferric sulfate (PFS) as flocculant could effectively enhance the treatment performance of the UF process on DOM. With 6 mg/L PAC, the removal efficiency of humic acid, fulvic acid, and sodium alginate by micro-flocculation combined UF process reached 79.95%, 63.25%, and 51.14%, respectively. Specifically, after micro-flocculation, micromolecular hydrophilic organic matter (e.g., fulvic acid) tended to form a compact cake layer. The macromolecular hydrophobic organic matter (e.g., humic acid) and macromolecular hydrophilic organic matter (e.g., sodium alginate) generally led to a loose cake layer. At PAC dosage of 6 mg/L, the membrane specific flux (J/J0) at the end was improved by 11.71%, 10.27%, and 2.2% for humic acid, sodium alginate and fulvic acid solutions, respectively, compared with the UF process alone. It could be inferred that micro-flocculation pretreatment can effectively mitigate the membrane fouling when treating wastewater containing humic acid, sodium alginate, or fulvic acid.
Migration crime in the Republic of Bashkortostan: features and trends
Authors: Egoryshev Sergey V.
Published: September 2021

The relevance of the article is determined by the fact that population migration, being a kind of horizontal mobility process, has both a positive and a negative impact not only on the demographic situation in the country as a whole and its regions, but also on many socio-economic and political processes taking place in them. The migration process and the socio-demographic groups participating in it have become the subject of study by specialists representing various branches of scientific knowledge. This allows, from the methodological point of view, from the standpoint of the ratio of the general and the particular, and at the interdisciplinary level, to study migration as a complex, contradictory, social process with significant latency. One of the problems that has not yet received proper scientific understanding is the impact of migration on the state of the crime situation in the new social environment. The study of this problem, which is the purpose of this article, will not only bring new knowledge to sociological and criminological sciences, but will also contribute to the improvement of migration policy, law enforcement and social work with migrants. The migration process and its participants have a complex structure and differentiation, therefore the research topic can be disclosed taking into account this differentiation, which is impossible to do within the framework of one article. Therefore, the object of analysis in the article is external migrants — foreign citizens and representatives of the CIS countries, and the subject is formed by the crimes committed by them and against them. The analysis also includes crimes related to migration. The empirical basis of the study was the data of demographic and criminal statistics for the period from 2012 to 2020, presented at the levels of Russia and the Republic of Bashkortostan. This made it possible to characterize the features, trends in dynamics and the content of the research subject. The established dependence of the external migration process dynamics and crimes committed by its participants should be investigated taking into account the criminogenic component general state of migration and the related possibilities of statistical accounting and sociological research that complements it. In the context of the topic under consideration, an author’s addition to the classification of migrants entering from abroad is proposed.
Rural development: a new microdistrict between the city and the village. Part 1. Theoretical analysis of social and territorial spaces of cities and villages
Authors: Davydenko Vladimir A. , Andrianova Elena V. , Filippova Tatyana M.
Published: September 2021

The first part of the work is devoted to the analysis of socio-territorial transforming one of the desolate rural lands from the perspective of an approach to phenomenological sociology. The goal is, from a theoretical point of view, to deepen the social construction scientific approach of locality, based on the study of the topological perspective between the city and the village according to such space properties as orientability, compactness and connectivity, when they remain invariant during construction changes in the working site of the territory. The methodology of structural and genetic operationalization of social space is used in terms of P. Bourdieu, rethinking the production of space by A. Lefebvre’s paradigm, its verification in terms of the phenomenology of A. Appadurai, the production of place as a center of meaning created by experience from interpretations of humanistic geography. The used combination of several paradigms provides a theoretically powerful basis for understanding how interlocal social relations, lifeworlds, and the found out identities of the territory inhabitants between the city and the village are interconnected. The theoretical object of research is local communities in rural and suburban areas. General hypothesis of the research: at present, a new modification of the concept of “rural” has emerged, especially to the extent that it is typical for any country in the world, while global trends in the suburbanization (isolation) of individual rural areas as various forms of peripheral urban development acquire a special (priority) value, challenging A. Lefebvre’s “urban revolution” paradigm in the sense that the space of the modern world is becoming totally urbanized. This article confirms the hypothesis about the spread of the global suburbanization of Roger Cale’s theory, which is becoming more widespread and more significant phenomenon in different countries and regions of the world. This is also evidenced by the ever-expanding geography of suburban research in post-socialist countries, as well as criticism of the derived meaning concept of suburbs in relation to urban centers. The empirical evidence of this article confirms the growing importance of peripheral urban development in various forms and, in a more general context, leads to an understanding of the need to revise urban social theory in the spread context of global suburbanization. The scientific novelty of the work lies in the author’s rethinking of the reproduction concept of space both at the symbolic level of local subjectivity and in specific ties to the life worlds of the new territories inhabitants of spatial development, with the author’s empirical confirmation of the proposed approaches, conclusions and presented databases.
The image of the future through the eyes of Ural students
Authors: Tarasova Anna N. , Telepaeva Daria F.
Published: September 2021

The study of the temporal attitudes of young people is one of the relevant topics, given the situation of uncertainty and riskiness in which society is today, including due to the COVID-19 pandemic. The problem considered in the article consists in identifying the social construction determinants of one’s personal future in conjunction with the future of one’s country in the minds of the younger generation. The purpose of the article is to show how students of the Urals see the future, to highlight changes in attitudes during a pandemic. The article is based on the data of the 8th stage of monitoring the student body of the Middle Urals, carried out in 2020, that is, during the coronavirus pandemic. A total of 2,000 students from 13 universities of the Sverdlovsk region took part in the survey. The paper uses the methods of descriptive analysis, the method of correlation analysis based on the Spearman coefficient, and the index method. According to the results of the study, a general tendency was highlighted: in the assessments of students, confidence in the future (post-COVID?!) day is lower than in the distant future. At the same time, the impact of the pandemic on the perception of their own future by students was not as strong as one might expect. Some contradiction is noted: assessing their present and future, students turn out to be more optimistic than assessing the future of the country. It is concluded that there is a bias in the temporal attitudes of students. Discrepancies in the images of the “desired” and “expected” future are indicated. Ural students speak about positive changes in the country much less often than about negative ones. Combined with a declining self-esteem of being protected (0.49) from persecution for political beliefs, this poses a potential threat that requires the close attention of all youth workers. It is recommended to form strategic thinking in young people, developing the ability to see future threats and problems, while they are just emerging and there is time to mitigate them or prepare for their impact.

Authors: Wijayanto Andi , Muktiati Nunuk Sri , Balâ€™afif Farhad , Rianawati Sri Budhi
Published: September 2021

Background: Tuberculosis is an infectious disease that develop from systemic infection caused by bacterium Mycobacterium tuberculosis complex. Generally, M.tuberculosis spread from one person to another through nuclear droplet air transmission. Although TB has a lower transmission rate compared to another infectious disease, TB still become a global health problem. It is estimated that approximately one third of the worldâ€™s population is infected by tuberculosis. Every year it is estimated that there are nine million new cases and close to two million death cases caused by tuberculosis.Case: A 24-year-old female was admitted to the hospital complaining of could not move both of her legs and could not urinate. One month before admission, she was diagnosed with meningitis TB; miliary TB; and meningioma at thoracic vertebrae T11-12 based on physical examination, laboratory examination, Chest X-Ray, Head CT Scan without contrast, and thoracolumbal MRI. When admitted to the hospital, the patient already treated with Fixed Dose Combination of antituberculosis Drugs first category for one and a half month from Turen Primary Healthcare. Then the patient underwent bronchoscopy examination. The result of the anatomical pathology examination showed class two. Then the patient underwent a laminectomy surgery and tumor excision at thoracic vertebrae T11-12. The result of postoperative Anatomical Pathology examination showed a neurofibroma pattern. After surgery, the Physical Medicine and Rehabilitation Department placed thoracic lumbosacral orthoses (TLSO) to the patient. Postoperative evaluation up to three months showed that the patientâ€™s general condition was quite good but still cannot move both of her legs and cannot urinate.

Authors: Tantular Rezki
Published: September 2021

Background: Tuberculosis (TB) is a major global health problem and South-East Asia was the leading contributor of TB cases globally. Treatment regimen of TB for an individual patient depends on multiple factors, and one of them was patientâ€™s comorbidities. Comorbidities such as renal failure or concurrent use of immunosuppressant drugs post renal transplantation will influence pharmacological aspect of anti-tuberculosis drugs.Case: A 38-year-old male with a history of chronic renal failure who had undergone routine hemodialysis was diagnosed with pulmonary tuberculosis and was scheduled for a renal transplantation procedure. During the administration of anti-tuberculosis drugs in this patient, the physician mustconsider the kidney function, and possible drug interactions between anti-tuberculosis drugs especially rifampicin with immunosuppressant drugs used after renal transplantation. The initialregimen used in this patient was RHE which was followed by RH, but after using immunosuppressant drugs, rifampicin was replaced with moxifloxacin to avoid suboptimal effect of immunosuppressant drugs to prevent donor rejection, which is the biggest contributor ofmortality in transplant recipients in the first year post-transplantation.

Published: September 2021

During the coronavirus disease 2019 pandemic in the United States, claims for unemployment insurance (UI) benefits rose sharply because of the substantial job loss and the expansion of UI programs. To improve upon UI administrative data, in this article, we use the Household Pulse Survey to estimate the number of people who applied for UI benefits, the number of people who received benefits, and the success rate of UI applicants (the share of applicants who received benefits) during the first 9 months of the pandemic. We examine differences by demographic group, educational attainment, and prepandemic household income. In addition, we relate state-level estimates to UI recipiency before the pandemic, job loss during the pandemic, and the differential spread of the coronavirus across states. Compared with individuals who applied for UI benefits but did not receive them, we find that individuals who received benefits had greater well-being in a variety of domains, including household finances, food security, and mental health.
Nursing Student Perceptions and Attitudes Toward Patients With Cancer After Education and Mentoring: Integrative Review
Authors: Hedenstrom Margot Lisa , Sneha Sweta , Nalla Anusha , Wilson Barbara
Published: September 2021

Background

Knowledge about nursing student attitudes toward patients with cancer after an educational intervention and mentoring support is limited. This review examined the literature on this topic.

Objective

This integrative review aims to explore the literature on the experiences of students who participate in an oncology elective or educational course on cancer and their attitudes toward cancer.

Methods

A comprehensive search was conducted using PubMed, CINAHL, and MEDLINE databases. Each study was systematically assessed. An evidence table was completed to identify the key aspects of each study that was reviewed.

Results

There is insufficient information on the impact of nursing student education on the attitudes and skills of nursing students caring for patients with cancer. An integrative review was completed on the impact of education and mentoring for nursing students on cancer care, which yielded 10 studies that were reviewed. These studies indicate that educational intervention and mentoring improve the confidence and ability of nursing students to care for patients with cancer.

Conclusions

Student nurses need to be armed with knowledge, skills, and positive attitudes while caring for patients with cancer. Nursing students perform best when they have accurate information, positive role models, and mentoring by experienced oncology professionals, to support proficiency in caring for patients with cancer. The lack of knowledge of nursing students in the areas of cancer care, treatment, and patient support requires additional education and research to promote expertise and positive attitudes toward cancer and treating patients with cancer. This will support nursing students’ ability to care for patients with cancer as well as develop future educational interventions to shape nursing student attitude and knowledge. This integrative review also identifies the positive impact on the attitudes of other health care professionals who have received training or education on cancer.
Identifying Player Types to Tailor Game-Based Learning Design to Learners: Cross-sectional Survey using Q Methodology
Authors: Van Gaalen A E J , Schönrock-Adema J , Renken R J , Jaarsma A D C , Georgiadis J R
Published: September 2021

Background

Game-based learning appears to be a promising instructional method because of its engaging properties and positive effects on motivation and learning. There are numerous options to design game-based learning; however, there is little data-informed knowledge to guide the choice of the most effective game-based learning design for a given educational context. The effectiveness of game-based learning appears to be dependent on the degree to which players like the game. Hence, individual differences in game preferences should be taken into account when selecting a specific game-based learning design.

Objective

We aimed to identify patterns in students’ perceptions of play and games—player types and their most important characteristics.

Methods

We used Q methodology to identify patterns in opinions on game preferences. We recruited undergraduate medical and dental students to participate in our study and asked participants to sort and rank 49 statements on game preferences. These statements were derived from a prior focus group study and literature on game preferences. We used by-person factor analysis and varimax rotation to identify common viewpoints. Both factors and participants’ comments were used to interpret and describe patterns in game preferences.

Results

From participants’ (n=102) responses, we identified 5 distinct patterns in game preferences: the social achiever, the explorer, the socializer, the competitor, and the troll. These patterns revolved around 2 salient themes: sociability and achievement. The 5 patterns differed regarding cheating, playing alone, story-telling, and the complexity of winning.

Conclusions

The patterns were clearly interpretable, distinct, and showed that medical and dental students ranged widely in how they perceive play. Such patterns may suggest that it is important to take students’ game preferences into account when designing game-based learning and demonstrate that not every game-based learning-strategy fits all students. To the best of our knowledge, this study is the first to use a scientifically sound approach to identify player types. This can help future researchers and educators select effective game-based learning game elements purposefully and in a student-centered way.
La naturaleza tutelar de las medidas cautelares en la Jurisdicción Especial para la Paz
Authors: Acosta-Alvarado Paola Andrea
Published: September 2021

En la teoría procesal, las medidas cautelares son herramientas judiciales que suelen concebirse como instrumentos para asegurar el buen desarrollo del proceso y el cumplimiento de las sentencias. Sin embargo, en el ámbito del derecho internacional de los derechos humanos (DIDH) la figura de las medidas cautelares ha venido desarrollando un rol tutelar, que tiene como fin último la protección de los derechos fundamentales. Este texto tiene como objetivo poner de presente la transformación que estas medidas han experimentado, a través del trabajo puntual de la Jurisdicción Especial para la Paz, órgano transicional que sigue el perfil del DIDH. Al demostrar esta nueva naturaleza tutelar de las medidas cautelares se quiere resaltar su importante papel en la tutela de los individuos y, más aún, en el éxito de la justicia transicional, que en Colombia tiene además perfil restaurativo.
Hacia una sistematización de los usos semánticos del concepto de dignidad humana en la protección internacional de derechos humanos: una revisión doctrinaria
Authors: Lafferriere Jorge Nicolás , Lell Helga
Published: September 2021

Este artículo se enmarca en un proyecto de investigación que indaga en la multiplicidad semántica que reviste el tér-mino “dignidad” en los casos contenciosos y en las opiniones consultivas de la Corte Interamericana de Derechos Humanos. Ello implica partir de la hipótesis de que dicha variedad de significados existe, y de que el análisis de este tópico es relevante, por cuanto permite clarificar el impacto de las posturas tomadas sobre la concreción de derechos. El trabajo que aquí presentamos constituye una primera aproximación al estado de la cuestión a partir de una revisión de las posiciones doctrinarias respecto de qué significados puede tener el término “dignidad”, con especial referencia a las normas e interpretación jurisprudencial en el ámbito de los derechos humanos. Esta revisión es útil para realizar una propuesta de sistematización y clasificación de esos posibles usos para futuros trabajos de investigación jurisprudencial.
Modelos de legitimación procesal constitucional en las entidades federativas en México: Una mirada al federalismo procesal constitucional
Authors: Rivera León Mauro Arturo
Published: September 2021

El presente artículo analiza los modelos de legitimación en acciones de inconstitucionalidad y controversias constitucionales establecidas por las diversas Entidades Federativas en el caso mexicano. El estudio argumenta que, dado el federalismo mexicano, Alemania es un adecuado término de comparación por ser un Estado Federal con modelos operativos de justicia constitucional local concentrada en los Länder. Sin embargo, el modelo alemán parte de una articulación constitucional. A diferencia del modelo alemán, el caso mexicano, no ha permitido generar estancos competenciales separados y se ha caracterizado por una competencia basada en la primacía y no el deslinde. Se concluye que, a falta de un adecuado deslinde de competencias en un federalismo procesal constitucional, la única esperanza para la operatividad de los modelos locales es generar incentivos para su empleo, como la legitimación de sujetos no contemplados en el esquema federal y no la simple duplicidad de legitimaciones.

En el presente trabajo se analizan las relaciones y tensiones entre el Poder Ejecutivo y el Poder Legislativo en asuntos militares y de defensa nacional en Argentina. Inspira-do en la investigación que Harlod Koh desarrolló en Estados Unidos, el objetivo es comprobar si, y en qué medida, el Ejecutivo prima sobre el Legislativo, tal como Koh lo hizo para el caso estadounidense. Mediante ejemplos históricos se aprecia que también es el caso en Argentina. No solo existe una primacía del presidente sobre el Congreso, sino que hay casos de abierta violación a la legislación sancionada por el segundo. Incluso pueden hallarse ejemplos de decisiones presidenciales tomadas en abierta contradicción de la Constitución. Finalmente, se buscan las razones constitucionales, históricas y políticas para que se dé esta primacía y se ofrecen ciertas pautas para pensar soluciones.
How Dare You! A Comparative Analysis of Constitutional Court Decisions Regarding Insult Laws in Mexico and South Korea
Authors: Won Yoomin
Published: September 2021

Las expresiones que critican al jefe de estado, las instituciones gubernamentales o los funcionarios públicos con frecuencia son sancionadas con castigo penal por su uso de lenguaje despectivo e irrespetuoso, denominado en la ley "insultos". Este artículo analiza cuatro decisiones de revisión judicial de la Corte Suprema de México y la Corte Constitucional de Corea con respecto a las leyes de insulto desde la perspectiva tanto del derecho internacional de los derechos humanos como del derecho constitucional. Sostengo que castigar criminalmente las expresiones insultantes dirigidas contra funcionarios públicos, símbolos o entidades, viola el principio de libertad de expresión. Primero, la "dignidad de la nación" no es un interés legítimo que garantice la restricción de expresiones insultantes dirigidas a las banderas nacionales o la República. Segundo, Se debe exigir a los funcionarios públicos que toleren un mayor grado de insulto que los particulares. La protección de una función pública, o el honor de un funcionario público, no justifica el castigo penal de las expresiones insultantes. Tercero, el término "insulto" en sí mismo es demasiado vago, por lo tanto, su uso viola el principio de claridad de la legalidad. También restringe sustancialmente la libertad de expresión al prohibir una amplia gama de expresiones y actividades. Con base en este análisis, sostengo que el castigo penal por expresiones dirigidas contra banderas nacionales, funcionarios públicos y la nación, debería eliminarse de los códigos penales. Ni los tribunales ni las autoridades gubernamentales deberían castigar penalmente las expresiones insultantes dirigidas contra los funcionarios públicos. Eliminar las leyes de insulto no dañaría, sino que fortalecería,
The Archetypal Merchant in the 1889 Mexican Commercial Code
Authors: Iturralde González Raúl
Published: September 2021

When creating laws, legislators bear in mind the subjects whose activities are to be regulated. This mental picture will affect the regulation of both, the subjects and their activities. Different perceived characteristics can be regulated in various ways. While the laws that regulated commerce in Mexico before 1889 were based on the concept of an honest merchant, the Commercial Code enacted by then President Díaz had a different archetypal merchant. Since 1889, commercial laws in Mexico have been enacted based on the idea of an untrustworthy merchant, someone who needs to be regulated and controlled, which has created a regulatory system riddled with unnecessary costs. Through the study of cases decided shortly after the enactment of the 1889 Code, the change in the perception of merchants and commerce becomes apparent. These cases show the strict application of rules in lieu of commercial customs and practices, and the idea of protecting those who are not merchants in their dealings from those who are. However, these ideas should be eliminated from commercial laws. The laws that regulated commerce in Mexico before the 1889 Code offer an excellent starting point for the reform of commercial laws. Laws that assume that merchants are honest and capable of regulating their own affairs will advance commerce in Mexico, which would in turn allow the country to become an innovator (as opposed to a follower) in commercial matters.
Predicting the Crop Type and Region of Abundance using Machine Learning

Abstract: In this modern age of science too technology, students and people in big cities ignorance of many things, such as how we get food, how things are processed, and much more. We are just it focuses on the results we get, because of this morality our knowledge diminishes, as if we did not know the crops or the goods ourselves using. As we visit the rural area when we arrive beyond some kind of plant, we can't know that, so we have identified this place to resolve the problem of students, researchers and many more people by creating a plant identification system which will predict the type of crop and the location of abundance where the harvest is planted.

Published: September 2021

Abstract: The purpose of this work is to investigate experimentally the surface roughness and MRR while machining of aluminium 2024 alloy which is prepared by powder metallurgical technique. Aluminium 2024 alloy prepared with different composition such as Pure Al, 1.5 W% of Mg and 2-6 % of Cu powders. Powders are blended with ball milling machine according to the composition required and specimens are prepared in square shape die (25*25mm) by applying uniaxial load of 200Mpa. The sintering process was performed at 594 0C for 60 min and cooled at room temperature. SEM and XRD analysis was carried out to know various characteristics like green density, dimensional changes during sintering, sintering density, mechanical properties and microstructures. Finally the Surface roughness and MRR during machining with CNC milling machine at different depth of cuts was also evaluated. Keywords: Aluminium 2024 alloy, surface roughness, MRR, SEM and XRD analysis
Directional Moiré Boosting Using Spatial Filtering
Authors: Chatterjee Joydeep
Published: September 2021

Abstract: Overlapping of two or more grating structures of small frequency differences gives rise to the Moiré patterns. While the overall moiré patterns are widely studied, in many cases – specially in case of a zonal fringe analysis – zone or direction based highlighting or suppression of moiré patterns are very helpful. This paper presents a simple method for directional boosting of moiré patterns, generated using Spatial Light Modulator (SLM) based interferometric setup, using the spatial filtering technique.

Incorporation of Rice Husk Ash as Partial Replacement of Cement in M40 Grade Concrete
Authors: Dar Musaib Bashir
Published: September 2021

Abstract: In this developing era concrete and cement mortar are widely used by the construction industry, with this development. Large number of industrial wastes are generated and if these wastes are not properly used it will create severe problems, keeping the environment in mind, concrete engineers are trying to find some alternative materials which will not only replaces the cement content but also improves strength of concrete. As we also know that during the manufacturing of cement large amount of Co2 is released into the environment, but if we use such material that will replace the quantity of cement content therefore indirectly, we are contributing towards the prevention of our planet from global warming and other pollutions. Also, in this research work the Rice Husk Ash is used. the rice husk ash obtained from the rice processing units, by adding this product with concrete, not only replaces the cement content but also increases the strength of concrete like compressive strength etc. The Rice husk ash was incorporated with concrete with varying percentages of 2.5% ,5% ,7.5%, & 10%. the proper codal precautions were followed during the manufacture of concrete cubes of 150x150x150mm. it was concluded that the strength of concrete increased by incorporated the rice husk ash.
