The early shoot borer, top borer, root borer, internode borer are major insect occurs in most of the sugarcane growing areas of the Gujarat and cause extensive damage to the sugarcane crop, which leads to losses in the crop yield. The weather discrepancies acting an important role in development of sugarcane insect and pest. The proper management of cropping practices may leads to overcome on it. Therefore it need to develop weather based approaches for forewarning the insect incidence which helps to farmers takes timely control measures to reduce the damage and yield losses due to this borer complex. Current study, relationship between insects incidence with weekly average weather parameters has been workout by using Karl-Pearson’s correlation approach on the 18 years of the data (2000-01 to 2017-18) in the Navsari district. The some of the weather variables were found significantly correlated with insect incidence. The multiple linear regression (MLR) and discriminant function analysis approach were adopted for statistical forewarning of the insect incidence. It was observed that MLR technique found better than discriminant function analysis for forecasting of insect incidence for forewarning of early shoot borer at 90 DAP and top shoot borer incidence at 5th month of crop season respectively.

Published: June 2022

Rice sheath blight caused by the soil-borne fungal pathogen Rhizoctonia solani Kuhn is an economically important disease in rice resulting in enormous yield losses worldwide. In the present investigation, a population constituting F3 lines resulted from the cross made between IC277332 (susceptible parent) and Tetep (resistant parent) were evaluated for sheath blight resistance and other agronomic traits over a season. The rice population lines were categorized into four groups viz., moderately resistant (11), moderately susceptible (63), susceptible (24), and highly susceptible (8), based on area under disease progress curve (AUDPC) values. During the study, nine moderate resistant lines showed, less AUDPC values in comparison to Tetep. Furthermore, 63 individuals (60%) exhibited moderate susceptibility with AUDPC values (677-987 per day). The principal component biplot analysis PC1 and PC2 showed 47.08% and 13.19% variation, respectively. The employment of Unweighted Pair Group Method of Arithmetic Means (UPGMA) cluster analysis led to the grouping of the 106 individuals into 2 major clusters A and B. The results suggested that none of the rice lines was resistant to sheath blight disease. However, few lines showed moderate resistance to the disease which can be exploited for the development of sheath blight-resistant cultivars.

Published: June 2022

A field experiment was conducted during Kharif 2019 at the Experimental Farm of the Department of Agronomy of CSK Himachal Pradesh Krishi Vishvavidyalaya, Palampur (H.P.) to investigate the effect of different tillage systems and varieties on yield of rice. The treatments consist of three rice varieties (HPR 1156, HPR 2656 and HPR 2795) which were tested under three tillage systems viz., conventional tillage, and minimum tillage without residue and minimum tillage with residue retention. The experiment was set up in a split plot design, with the tillage system in the main plot and rice cultivars in the sub plots, and it was triple replicated. The texture of the soil at the test site was silty clay loam in texture, acidic in reaction and in terms of nitrogen, phosphorus, and potassium, it was evaluated as medium. Significantly higher no. of panicles per meter square were observed in minimum tillage without residue though this treatment was at par with conventional tillage while significantly lower number of panicles m-2 were recorded with minimum tillage with residue retention. Significantly greater number of grains per panicle and panicle length were recorded in conventional tillage while minimum tillage with residue retention recorded lower values of number of grains per panicle and panicle length. Different tillage practices had no effect on the test weight of rice. Among different varieties tested, HPR 2656 recorded greater number of panicles per square meter which was at par with variety HPR 1156. Significantly higher number of grains per panicle and panicle length were recorded with HPR 2795 while the other two varieties were at par with each other. Rice variety HPR 1156 produced grains that had significantly greater test weight while the other two varieties (HPR 2795 and HPR 2656) were at par with each other with respect to this parameter. In terms of yield, conventional tillage produced much larger grain yield, straw yield, and biological yield and was at par with minimum tillage without residue. Among different varieties tested, HPR 2795 recorded much greater grain, straw and biological yields.

Published: June 2022

Controlled fire effect on nutrients and physico-chemical properties of soil was investigated after a span of one year of controlled fire under four land uses viz. chir pine forest (Pinus roxburghii), grassland, scrubland and non-fire site in chir pine (control). In March 2018, a controlled fire was caused, and soil samples were taken after one year of burning at different soil depths (viz. 0-5 cm, 5-10 cm and 10-15 cm). The experiment consisted of five replications in factorial randomized block design. The results revealed that in comparison to pre-fire assessment, available nitrogen, phosphorus and potassium slightly increased, whereas, soil organic carbon decreased slightly in post-fire assessment. The soil pH, electrical conductivity, bulk density and soil texture did not show any significant change after one year of burning. The study concludes that controlled fire did not cause any drastic fluctuations in nutrients and physico-chemical properties of soil and can be used as an effective management practice for combating the negative effects of wildfire on soil.

Published: June 2022

Maintenance of good health and avoiding a viral infection is the prime focus for an individual during COVID-19 pandemic. Water being a universal solvent is used widely to clean the disinfectants in public places and individual household level. This study was designed to find any change in the water consumption pattern among the households after the emergence of COVID-19. To study this, a questionnaire was prepared and sent to the respondents through Google Forms. Collected data was analysed using suitable statistical methods and the results indicate that there was a significant change in the consumption pattern of drinking water from cold to hot (37.98%) among the respondents and also with respect to the total water usage. As the disease is communicable in nature, more water is needed to clean and disinfect the surface areas, washing hands etc. This eventually has a significant burden on the water resources in countries where water is already deficient, like India. It is recommended to adopt water conservation practices/technologies at the individual level by means of rain water harvesting techniques or use of efficient water aerator taps etc. to reduce water consumption.

General Principles of Medical Cancer Treatment
Authors: Hunis Adrian P.
Published: June 2022

Cancer is a global health problem responsible for one in six deaths worldwide. Treating cancer has been a highly complex process. Conventional treatment approaches, such as surgery, chemotherapy, and radiotherapy, have been in use, while significant advances are being made in recent times, including stem cell therapy, targeted therapy, ablation therapy, nanoparticles, natural antioxidants, radionics, chemo dynamic therapy, sonodynamic therapy, and ferroptosis-based therapy. Current methods in oncology focus on the development of safe and efficient cancer nanomedicines. Stem cell therapy has brought promising efficacy in regenerating and repairing diseased or damaged tissues by targeting both primary and metastatic cancer foci, and nanoparticles brought new diagnostic and therapeutic options. Targeted therapy possessed breakthrough potential inhibiting the growth and spread of specific cancer cells, causing less damage to healthy cells. Ablation therapy has emerged as a minimally invasive procedure that burns or freezes cancers without the need for open surgery. Natural antioxidants demonstrated potential tracking down free radicals and neutralizing their harmful effects thereby treating or preventing cancer. Several new technologies are currently under research in clinical trials, and some of them have already been approved. This review presented an update on recent advances and breakthroughs in cancer therapies [1,2].
Influence of Wind Angle Incidence and Architectural Elements on the External Pressure Coefficient of Hyperbolic Paraboloid Roofs
Authors: Teixeira Guilherme S. , , De Campos Marco D.
Published: June 2022

In the study of wind loads in buildings, the aerodynamics of roofs with parabolic shapes, which cause complex pressure distributions due to their sensitivity to wind, are often omitted and neglected by several codes and norms. In this way, computer simulations are a viable and reliable alternative. Here, wind action was considered in an innovative project composed of parabolic and circumferential generatrices: the Church of Saint Francis of Assisi. Designed by Brazilian architect Oscar Niemeyer in Belo Horizonte, Brazil, two paraboloid vaults and three circular arches of reinforced concrete composed its structure. This work generated great international recognition for the architect after 1943, as the design of the roofs did not require walls. For geometry modeling, Autodesk AutoCAD software was adopted, and the models were considered in a control volume. The simulations were performed using Ansys Workbench software and the RNG K-Epsilon turbulence model. The wind speed at different heights was calculated using the Power-law approximation. A basic wind speed of 30 m/s was adopted, and the mesh used was composed of tetrahedrons. To validate the methodology, different models with hyperbolic-paraboloid roofs from the literature were considered. In addition, the visualization of the flow around the geometry from the streamlines, the wind profile, and the analysis of the isobaric lines of the external pressure coefficients for different directions of incidence and architectural elements that make up the building were presented.
A Comparative Study of Statistical and Deep Learning Models for Energy Load Prediction
Authors: Gjika E. , Basha L.
Published: June 2022

The objective of this study is to analyze and compare classical time series and deep learning models for energy load prediction. Energy predictions are important for management and sustainable systems. After analyzing the climacteric factors impact on energy load (a case study in Albania) we considered classical and deep learning models to perform forecasts. We have used hourly and daily time series for a period of three years. In total respectively 26,280 hours and 1095 days. Average temperature is considered as external variable in both statistical and deep learning models. The dynamic evolution of hourly (daily) load is correlated with hourly (daily) average temperature. The performance of the proposed models is analyzed and evaluated based on accuracy measurements (MSE, RMSE, MAPE, AIC, BIC etc.) and graphics results of statistical tests. In-sample and out-of-sample accuracy is evaluated. The models show competitive performance to some recent works in the field of short-and medium-term energy load forecasts. This work may be used by stakeholders to optimize their activities and obtain accurate forecasts of energy system behavior.
An Innovative Vortex based Complex Potential Signature for Shape based Object Recognition
Authors: Mani M. Radhika , Srikanth T.
Published: June 2022

An Innovative approach for representation and description of shape components for object recognition based on complex potential is proposed. In the complex plane, the flow of velocity is a crucial factor to discriminate different shapes. Hence, the present paper computes the potential flow by transforming the shape of the input object into complex plane. The present paper computes the Vortex based Complex Potential signature (VCP) by considering the radial lines as Equipotential lines and the circles as streamlines. The proposed VCP signature is described with the Fourier transformation for the generation of feature vector. The Chebyshev distance measure is used in the shape toning stage. The efficiency of the proposed descriptor is evaluated with the MPEG-CE-1 Set B database. The results prove the competency of the proposed descriptor than the benchmark descriptors
Main Theoretical Approaches in the Arctic Policy Studies
Authors:   Saint Petersburg State University, Nabok Sergey D.
Published: June 2022

The article identifies and analyzes the main theoretical approaches used in the studies of international relations and politics in the Arctic. Contemporary studies of the Arctic use elements of several main approaches in the field of international relations: realism, liberalism, social constructivism and global gov-ernance, as well as some others. The theoretical alternative between realism and liberalism manifests itself primary in the issues of Arctic security. Liberalism and the concept of global governance play an important role in explaining the multilevel and multi-actor nature of political processes and governance in the region. Social constructivism contributes to the understanding and functioning of Arctic political narratives. However, in most cases, they exist in the form of implicit assumptions rather than as systematically developed and substantiated models. The theoretical differences are mainly related to the definition of units and levels of analysis, particularly the role of states and other types of actors, and the nature of the relationship between them. Despite the fact that realistic approaches considering Arctic politics as inevitable competition of states in the logic of “zero-sum games” remain quite common, the general tendency is to search for more complex theoretical models that recognize the diversity of actors involved in Arctic processes, as well as the possibility of cooperative relations.

The article discusses the special characteristics of the territorial mobility of the population of the Republic of Sakha (Yakutia). Changes in the migration situation, structure of migration and migration activity of the population in different social and economic zones of the region in the context of the coronavirus pandemic are analyzed. The analysis shows that the peculiarities of distribution of productive forces and human resources in the labor market retain a fairly high potential for labor migration to the Republic of Sakha (Yakutia) from the CIS countries and far abroad in the context of a pandemic, the share of arriving migrants indicating work among the reasons for migration continues to grow. The influence of socio-economic characteristics and urgent problems of the republic on the formation of migration activity and migration intentions of the population is considered. The article is based on the results of a mass survey in Yakutia (n=200). Analysis of the survey results shows that the features of territorial mobility, migration intentions of the population and absence of migration plans depend on the socio-economic conditions of residence, various factors of individual social status and position, and mobility resources. With mostly satisfactory assessments of the socio-economic situation in the republic and most factors of social life in the region, the respondents’ migration intentions are conditioned by low incomes and territorial specifics — remoteness from the central regions of the country, the high cost of air fares and harsh climatic conditions. In the pandemic conditions, the spatial mobility of the population, as one of the most important social resources of society, is most characteristic of the part of young people who have financial resources, unmarried, seeking better socio-economic and climatic conditions, to regions with better infrastructure, where they can get a decent job, quality education, medical services, recreation and leisure.

Published: June 2022

This article is devoted to the Arctic as the territory of an ancient developed civilization existence; the territory that gave the world the Russian language, which later spread throughout the world; the territory where archaeological and anthropological artifacts have been preserved, allowing us to speak about the primacy of the Aryan (Russian) people, and, consequently, about the primacy of the ancient language of the Aryans. The authors of the article give the examples of excavations, the names of toponyms, hydro-nyms, ornaments on clothes, vessels, household items, proving the life of people in the Russian North many thousands of years before the Sumerian, Persian, Indian, Egyptian, Chinese civilizations; represent the opinion of scientists from around the world; try to find “traces” of the Russian language in other languages of the world. The authors of the article made a comparative analysis and demonstrated the interconnection of several languages on the example of some words, presented information on the Russian alphabet and showed its connection to the English signs of transcription. The hypothesis about the primacy of the Russian language is based on the statements of well-known domestic and foreign linguists, dialectologists, ethnographers, historians, slavists, sanskritologists, paleontologists, paleoclimatologists, soil scientists, and other researchers and requires further study.

In the modern realities of the global change in the technological order and the emergence of a post-industrial society, innovative activity strengthens its significance as the most important resource for socio-economic development. Territorial differences in the potential for innovative development, which impede the effective integration of the northern regions into a single innovation system of the country, predetermine the need for a deep study of the problems of their development and the study of the main factors and prospects in the field of innovation. The study focuses on the northern regions of the European part of Russia, since they concentrate more than half of the human potential of the North and determine the strategic prospects for the development and strengthening of national security in the Arctic zone of the Russian Federation in the face of existing risks and challenges: environmental, social, economic and geopolitical. The purpose of this work is to identify prospects and to assess the current state of innovative development of the northern regions of the European part of Russia. In order to achieve the goal, the methods of statistical and comparative analysis, the dialectical method were used. The informational basis of the study was made up of data from Rosstat and the departmental civil service at the regional level. The analysis demonstrates the differentiation of the regions of the northern European part of Russia at the level of innovation and regional economic systems that include it. The most important prospect of overcoming the weaknesses of regional innovation systems is their integration and mutual complementarity, which is sometimes achievable with new systemic tools for the spatial organization of the economy, in particular, the special economic regime of the Arctic zone of Russia. The study was conducted on the example of five regions of the European North of Russia: the Arkhangelsk Oblast, the Murmansk Oblast, the Republic of Karelia, the Komi Republic and the Nenets Autonomous Okrug.
Both task-irrelevant and task-relevant information trigger reactive conflict adaptation in the item-specific proportion-congruent paradigm

Adapting attention flexibly is a fundamental ability of the human control system. In the color-word Stroop task, for example, congruency effects are typically smaller for colors and words that appear mainly in incongruent stimuli (mostly-incongruent items) than for colors and words that appear mainly in congruent stimuli (mostly-congruent items). At least part of this item-specific proportion-congruent (ISPC) effect is due to a process of reactive conflict adaptation that affords higher selectivity (i.e., more efficient selection of task-relevant information) when a specific stimulus is presented that is frequently associated in the experiment with conflicting task-irrelevant information. What is unclear, however, is whether, normally, this stimulus-specific adaptation is triggered by the task-relevant component, the task-irrelevant component, or both components of the stimulus. In two experiments, using modified color-word (Experiment 1) and spatial (Experiment 2) Stroop tasks that allowed task-relevant and task-irrelevant triggering processes to be dissociated, we found that the two processes have approximately equivalent impacts. Because these results were obtained in experiments imposing no limitations on the processes potentially contributing to the ISPC effect, these results challenge claims that the ISPC effect involves conflict-adaptation processes only in special situations. The ISPC effect may involve conflict-adaptation processes in most situations, with both task-relevant and task-irrelevant information triggering such processes.

La educación superior ha optado por ofertar cursos tanto en modalidad presencial, así como en modalidad virtual para brindar un panorama amplio en el ámbito educativo. El objetivo de esta investigación ha sido por un lado, resaltar la importancia de integrar un plan de asesoría a través de interacción y comunicación entre el profesor y estudiante en un curso e-learning y por otro lado, detectar la problemática que existe con el ejercicio de comunicación e interacción a través de los cursos virtuales. Para demostrar lo anterior, se utilizó el método descriptivo, bajo el paradigma positivista, con enfoque cuantitativo, diseño experimental y tipo correlacional. El instrumento tipo cuestionario con 53 ítems. La escala de medición utilizada en las preguntas fue una escala Likert de 5 puntos con las variables de interacción y, seguimiento y asesoría. Dicho cuestionario se aplicó a profesores de la Facultad de Informática de la Universidad Autónoma de Querétaro. Para el procesamiento y análisis de los datos se utilizó la medición de Alfa de Cronbach, el cual resulto de 0.947 siendo fiables para continuar con la investigación. Los resultados demostraron una ausencia en la implementación de planes de asesoría para atender dudas de los estudiantes, siendo un factor importante dentro de la variable de seguimiento. Lo anterior, lleva a la propuesta de estrategias de comunicación e interacción entre el profesor y estudiante para el desarrollo de un proceso de enseñanza-aprendizaje satisfactorio.

Published: June 2022

Con el paso del tiempo, la concepción de la lectura ha cambiado y junto a ella sus procesos y estrategias.  En la lengua castellana, la lectura y escritura son dos términos que no solo se pueden definir como pilares de la educación, sino, que, además, son nominados como habilidades humanas que permiten discernir y plasmar el conocimiento. El objetivo fue fortalecer las habilidades comunicativas en los estudiantes, a través de la propuesta literaria de María Teresa Andruetto, para incitar el interés por la lectura de diversos textos, lo cual contribuyó en la consolidación de un pensamiento crítico y en la formación de sujetos activos intelectualmente. La investigación se realizó bajo el paradigma humanista, de enfoque cualitativo, diseño de investigación-acción y tipo practico. La población a la cual se aplicó la propuesta fue a un grupo de 12 estudiantes, los cuales se mostraron durante cada una de las clases participativos e interesados por los libros trabajados. Se realizó una encuesta, para recolectar información relacionada a la cantidad de libros leídos durante el último año. La validación obtenida surgió al realizar el análisis de cada uno de los talleres diseñados para cada sesión y posteriormente se estableció una triangulación con los instrumentos utilizados para la recolección de datos. Finalmente, mediante la aplicación de estrategias de comprensión lectora en la literatura infantil, se logró fortalecer los niveles de comprensión, e incitar el interés por la lectura, logrando así sujetos activos, con más posibilidades en la consolidación de un pensamiento crítico.

The impacts of secondary education reforms on schooling and income of women and men in the Philippines
Authors: Revilla Ma. Laarni , Estudillo Jonna
Published: June 2022

In 1988 and 1989, the Philippine government implemented free public and subsidized private secondary schooling through two major policies, namely Republic Act (RA) 6655 and RA 6728. This study investigates the long-run impacts of the two policies on schooling attainment and income using a regression discontinuity design (RDD). It draws data from the Annual Poverty Indicators Survey 2008 and 2011. We present two main findings. First, younger cohorts of women and men, who are policy beneficiaries, have significantly higher educational attainment relative to non-beneficiaries. Second, an additional year of schooling significantly increases individual income of women in the informal sector and men in the formal sector. In brief, our findings suggest that the policies are effective in enhancing schooling attainment, but the downstream impacts appear to have accrued substantially to women employed in the informal sector and men employed in the formal sector.
Who benefits from Dual Training Systems? Evidence from the Philippines
Authors: Igarashi Takiko , Acosta Pablo
Published: June 2022

Rising youth unemployment rates have been increasingly recognized as a serious challenge in developing and advanced economies, suggesting a potential skills gap between the demand and supply of recent graduates. Effective dual education programs which utilize a combination of classroom instruction and practical skill training are usually presented as an approach to develop a skilled workforce and meet employers’ demands. This paper analyzes data from a recent survey tracking graduates from the Philippines’ Dual Training System (DTS), as well as from regular programs provided by technical vocational training institutes. The evidence suggests that the DTS has a signi!cantly higher rate of returns on labor market earnings than regular, classroom-only vocational training programs, particularly among high school graduates who did not perform well academically during basic education. The magnitude of the impact of the DTS is also likely to increase in correlation with the intensity of the on-the-job component.
Azcárraga’s critique of mercantilism: trade as an engine of growth
Authors: de Dios Emmanuel
Published: June 2022

Manuel Azcárraga y Palmero's La libertad de comercio en las islas Filipinas (1872) was an unequivocal and consistent tract advocating free trade as a commercial policy for the Philippines. It is remarkable for its explicit and frequent reference to free-trade theory and the example of other nations (notably Britain and its colonies) as a guide to policy. It uses a historical approach in its critique of Spanish mercantilist ideas and biases, which are held responsible for centuries of foregone development opportunities for the Philippines. This article traces Azcárraga’s arguments and links them to Smith’s [1776] theory of international trade and its later elaborations (Myint [1958, 1977] and Schumacher [2015, 2016]). The protectionist mindset and policies Azcárraga believed to have held back Philippine progress one hundred !fty years ago are a striking portent of issues hounding the country’s development in the 20th century and even later.
