Authors: Fihudha Ganis Dina , Sari Irma Mustika
Published: August 2023

Smoking has become a familiar habit, especially among teenagers. Youths are more likely to use cigarettes at a young age without regard for the potential consequences and their lack of self-awareness and therefore pay no attention to the dangers of their use. Early on in an attempt to reduce the tobacco epidemic. Knowledge of the dangers of electronic cigarettes is little known to young people, and the lack of exposure to teenagers on electronic cigarettes can cause it. This research aims to get an overview of the level of adolescent knowledge about the dangers of electronic cigarettes in health in Bhinneka Karya Surakarta Vocational High School. In the study, the method used is quantitative descriptive with a total of 75 respondents and stratified random sampling sampling taken. The instruments used were questionnaires. The results of 75 teenagers fall largely in the adequately known category of the dangers of electronic cigarettes: 42 (56.0%), 30 (40.0%) fall in the less category, and only 3 (4.0%) in the good category. It could be concluded that the level of teen knowledge about the dangers of electronic cigarettes in Bhinneka Karya Surakarta Vocational High School is adequate.
Variability of Income Flows of Tourism Companies during a Nine-Year Period
Authors: Felicetta Iovino
Published: August 2023

The global financial crisis has affected all countries during the period 2007-2014. Tourist companies, especially in Italy, play a significant role in the economy of a country. The performance of tourism companies, and in particular hotels and travel agencies and tour operators, will be analysed in this paper, relative to the period of the crisis. The aim of this paper is to analyze profitability dynamics of the aforementioned tourist companies, to check whether they have suffered the effects of the global crisis. To this end, data from AIDA database relating to Italian companies in the sector were used. The profitability of these companies has been analyzed using the main profitability ratios, ROI and ROS ratios. An analysis of the trends and ANOVA of these ratios was carried out for the period 2007-2015. In this way, it has been verified whether the global crisis has affected profitability dynamics of hotels and travel agencies and tour operators in Italy. There is a parallelism in the trends of the main operators' indices in the three Italian macro-regions. The best performance is in the South, in a less developed economic context. The crisis has reduced the income indices in the first three years, even if the figure remains positive. Since 2012 there is a clear recovery, especially for hotels; intermediaries, on the other hand, suffer from competition from websites. However, the indices confirm the close relationship between travel agencies, tour operators and hotels. ROI mainly rewards first, while ROS intermediaries.

The holy Quran is the eternal charter of guidance and code of conduct for the people So man should pay attention to the holy Qura'an and understand its teachings through the path of the companions of Holy Prophet Muhammad (P.B.U.H), who were the eye witness of the revelation of Qura'an and we're successful in life practicing upon the Doctrine of Qura'an. Since then, a successful group has been there who not only tries to comprehend Qura'an but struggled to explain the true meanings of Qura'an to their fellow beings. One of these strives is the "Tafsir al-Sha'ravi". It counts in golden chain of tafasir and written by "Sh. Mohammad Metwalli al- Sha'ravi". The common Muslims in general and the Muslim youth in particular must be well aware of the comprehensive methodology of the interpreter.In this article the important and distinctive features of "Tafsir al-Sha'ravi" have been described analytically.
Optimal energy decay rates for viscoelastic wave equations with nonlinearity of variable exponent
Authors: Mustafa Muhammad I.
Published: August 2023

In this article, we consider the viscoelastic wave equation $$ u_{tt}-\Delta u+\int_0^{t}g(t-s)\Delta u(s)ds+a| u_t| ^{m(\cdot )-2}u_t=0 $$ with a nonlinear feedback having a variable exponent \(m(x)\). We investigate the interaction between the two types of damping and establish an optimal decay result under very general assumptions on the relaxation function \(g\). We construct explicit formulae which provide faster energy decay rates than the ones already existing in the literature.

Principles of Soil and Water Analysis
Authors: Panda Narayan
Published: August 2023

Sustainable agricultural management approaches in the soil environment is the key to sustained food security, soil quality and livelihood security. The damage to soil fertility and depletion of plant nutrient elements in soil has emerged as major threats to the sustainability of diverse agricultural production systems. Therefore, soil and water testing is considered an important tool to assess the essential plant nutrient elements need to formulate crop and site specific nutrient recommendations vis-à-vis climate change strategies. Soil test based nutrient use optimizes economic returns and minimizes risks of environmental pollution. Characterization of soil mineralogical, microbiological or biochemical properties within an experimental area among different treatments or cropping systems it requires the utmost attention to planning details. It is imperative to establish experimental objectives as a prelude to developing the sampling plan. As a component of development of sampling plan, one must begin by evaluating the environment from which samples will come. To accomplish this goal one must determine the physical and chemical features of the experimental area that includes the basic agents of nutrient supply i.e. soil and water. It contains principles and reactions of chemical analysis, soil sampling and analytical techniques for the determination of physical and chemical parameters of soil and water samples. The book on “Soil and Water Analysis” will be helpful to the Soil Chemists, Agriculture Officers, Specialists and research scholars of soil testing laboratories and other laboratory technicians/assistants.

Entrepreneurship Development in Specialty Agriculture: Entrepreneurship and Skill Development Series: Volume 04
Authors: Kachroo Jyoti
Published: August 2023

The specialty crop sector has been consistently growing over the last decade at national and international level. However, the COVID-19 pandemic has presented unique challenges to the industry that threaten its continued growth, while at the same time prompting a positive trend in consumer preferences for direct farm specialty crop purchases. Performing some processing functions on-farm before selling their crops, producing higher-value specialty crops, building direct marketing opportunities that bypass middlemen, and looking for niche markets are other ways that farmers can capture a larger share of the economic value of what they produce. These additional benefits would increase economic activity and enhance entrepreneurship development. Therefore, the book on 'Entrepreneurship Development in Specialty Agriculture' is aimed to discuss the role of specialty agriculture in development of enterprises.
Specialty Agriculture
Authors: Kachroo Jyoti
Published: August 2023

The Indian agriculture sector has experienced buoyant growth in the past two years. A trend accompanying growing consumption and increasing production is the qualitative shift to special agriculture. There has been a marked shift in production from basic foodgrains to high value produce, especially fruits and vegetables. Specialty agriculture involves commercial agricultural operation, other than a confined feeding operation, which requires smaller tracts of land due to the intensive nature of the operation. It includes nurseries, greenhouses, mushroom farms, market gardens and apiaries. Future research should examine alternative approaches to develop this important cluster of economic activity. Identifying new locations for farmers' markets, expanding sales at existing farmers' markets, and identifying opportunities for producers to sell specialty crops to new value-added markets could be among possible growth strategies. Therefore the book on 'Specialty Agriculture' is aimed to discuss the role of Specialty agriculture in economic development of India.

Unexpected Isomerization of Oxetane-Carboxylic Acids – catalyst design.
Authors: Rzepa Henry

Previously, a mechanism with a reasonable predicted energy was modelled for the isomerisation of an oxetane carboxylic acid to a lactone by using two further molecules of acid to transfer the proton and in the process encouraging an Sn2 reaction with inversion to open the oxetane ring. We are now ready to explore variations to this mechanism to see what happens.

Razões para agir e normatividade: uma crítica ao internalismo de razões
Authors: Oliveira Marco

O internalismo de razões é uma teoria sobre a normatividade das razões para agir. De acordo com internalistas, a força normativa das razões tem origem nas nossas valorações e preferências. O presente trabalho tem por objetivo apresentar a critica externalista à interpretação de razões para agir defendida por internalistas. A critica consiste em afirmar que os estados motivacionais dos agentes não são suficientes para abarcar o fenômeno da normatividade.

Este texto visa estabelecer um percurso na obra de Søren Kierkegaard sobre a questão da consciência. Vamos partir da verdade e da dúvida no texto Johannes Climacus ou É preciso duvidar de tudo. Em seguida consideraremos alguns textos da obra Ou...Ou, finalizando com considerações acerca do eu em Doença até a morte, assinada pelo pseudônimo Anticlimacus. Desta forma, estaremos apresentando um estudo inicial acerca da problemática da consciência em Kierkegaard.  Referências bibliográficasFERRO, Nuno. Estudos sobre Kierkegaard.

Derrida <> Lacan: o gozo de uma parceria
Authors: Henriques Rogério Paes , Vidal Paulo
Published: August 2023

Aborda-se a relação entre Derrida e Lacan com base na teoria do parceiro, que apresenta uma modalidade de enlaçamento entre o ser falante e o Outro, via gozo, extraída do fim do ensino de Lacan. O eixo norteador será o texto derridiano “Pour l’amour de Lacan”. Acrescenta-se a dimensão real da pulsão (atrelada ao objeto a e ao gozo) à perspectiva do significante, com a qual geralmente se lê a relação entre tais pensadores. Esta relação teria sido mediada pela intrusão do objeto voz, sendo a parceria resultante escrita no par ordenado amorte.
O conceito de governamentalidade em Michel Foucault
Authors: Oliveira Lorena Silva
Published: August 2023

O presente artigo objetiva apresentar o conceito de governamentalidade no pensamento de Michel Foucault. Para tanto, percorre as reflexões empreendidas pelo filósofo desde as técnicas de governo das almas inventadas pela Igreja, com o poder pastoral, até o neoliberalismo no século XX, tendo como principal subsídio teórico seus cursos ministrados no Collège de France, que originaram as obras “Segurança, Território, População” (1977-1978) e “Nascimento da Biopolítica” (1978-1979. Em tais obras, o filósofo analisa as práticas governamentais, utilizando o conceito de governamentalidade para examinar a racionalidade política desenvolvida no Ocidente.
