Authors: Botesini Gabriele Da Graça , Kumpel Daiana Argenta , Zanchim Maria Cristina , Alves Ana Luisa Sant'Anna
Published: May 2023

O objetivo foi verificar a ocorrência de hiperglicemia em pacientes críticos em uso de terapia nutricional enteral (TNE). Estudo de caráter transversal, observacional, com pacientes críticos, adultos e idosos, de ambos os sexos, em uso de TNE exclusiva via sonda ou ostomias por período ≥ 72 horas, internados na unidade de terapia intensiva. A amostra total foi de 66 pacientes com idade entre 18 e 87 anos, sendo a maioria homens idosos. O principal motivo de internação foram doenças neurológicas. Houve associação significativa com o diagnóstico de diabetes mellitus (p = 0,002), medicamentos (p < 0,004), protocolo de aplicação de insulina (p < 0,001) e dieta (p < 0,001). Não houve associação com desfecho clínico (p = 0,119) e período de internação (p = 0,279). Os pacientes com controle estrito da glicemia, verificou-se a prevalência de óbito (80%), com associação significativa (p = 0,022). Todos os pacientes hiperglicêmicos que fizeram uso de formulação para controle glicêmico obtiveram melhora significativa na glicose (p < 0,001). A elevada ocorrência de hiperglicemia em pacientes críticos que utilizam TNE é influenciada pela caraterística da dieta ofertada e utilização de protocolo insulínico.

Published: May 2023

Evidências demonstram que idosos que desempenham dupla tarefa podem ter menor risco de quedas. Idosos institucionalizados apresentam maior risco de quedas que os da comunidade, e a atendimento fisioterapêutico pode reduzir esse risco. Com isso o presente artigo busca identificar o desempenho em atividades de dupla tarefa de idosos institucionalizados que são tratados com fisioterapia, e a associação com o risco de quedas. Para isso realizou-se um estudo transversal, quantitativo e descritivo, realizados em uma instituição de longa permanência do Distrito Federal. Fizeram parte da amostra idosos residentes da Instituição de ambos os sexos com idade igual ou superior aos 60 anos que executaram testem escala de Berg, TUG, e teste de dupla tarefa. Não tiveram diferenças significativas, entretanto a idade aumenta os riscos de queda pois altera capacidade funcional de realizar dupla tarefa, o TUG indica que o individuo que possui indicativo de maior risco de queda não tem bom desempenho na dupla tarefa (*p<0,005). Pode-se concluir que o desempenho em atividades de dupla tarefa tem correlação com o risco de quedas. Quanto melhor for a execução da dupla tarefa menor será o risco de quedas. O grupo que realizou fisioterapia apresentou melhores resultados na realização da dupla tarefa.

Published: May 2023

O envelhecimento, enquanto um processo natural submete o organismo a alterações anatômicas e funcionais que repercutem nas condi­ções de saúde e no estado nutricional do idoso. A alimentação na terceira idade requer uma maior atenção, já que as alterações fisiológicas no organismo do idoso podem modificar as necessidades e o estado nutricional. Em alguns estudos tem sido demonstrada a relação tanto do índice glicêmico quanto da carga glicêmica com componentes da síndrome metabólica, dentre eles, a resistência periférica à insulina. O objetivo do trabalho foi avaliar o índice glicêmico e carga glicêmica da dieta de idosos correlacionando-os com seu perfil nutricional. Como instrumentos metodológicos foram utilizados avaliação antropométrica, questionário de estilo de vida e recordatório de 24 horas, protocolo de Brand-Miller, Foster-Powell, Atkinson (2009) e a tabela de medidas caseiras de Pinheiro et al. (2013). Os participantes foram idosos não institucionalizados frequentadores de um grupo de convivência em uma entidade social na cidade de Fortaleza, Ceará. A amostra revelou uma proporção maior de mulheres (n=65) do que de homens (n=18). Constatou-se que 51,81% (n=43) dos idosos estavam eutróficos, 31,32% (n=26) com excesso de peso e 16,87% (n=14) com baixo peso. Foram observadas inadequações quanto ao índice glicêmico e carga glicêmica em maior proporção no grupo com excesso de peso. Foi possível notar também uma forte relação causada para elevação da carga glicêmica dietética com a ingestão de alimentos com alto índice glicêmico.

Authors: Vieira Elciana de Paiva Lima , Alves Júnior Edmundo Drummond , Gurgel Jonas Lírio
Published: May 2023

O comprometimento do controle postural e a perda da flexibilidade característicos do processo de envelhecimento podem contribuir para episódios de quedas. Embora a hidroginástica desencadeie melhorias no controle postural e na amplitude de movimento articular, pouco tem sido investigado sobre seu efeito crônico na relação entre estas variáveis em idosos. O objetivo do estudo foi investigar o efeito crônico da prática da hidroginástica na relação entre controle postural e amplitude articular de movimento em idosas. As voluntárias são praticantes de hidroginástica do programa Prev Quedas há um ano. A avaliação do controle postural se deu pelos testes de Alcance Funcional, Lateral e Apoio Unipodal e, a amplitude articular máxima de movimento avaliada através da Goniometria. Foram realizados os testes de correlação de Pearson para dados paramétricos e de Spearman quando não paramétricos. Não foram encontradas correlações fortes entre o controle postural e amplitude articular de movimento. Os dados apontaram que a prática da hidroginástica de longo prazo melhora a capacidade de Alcance Funcional (28,96 ± 6,42 cm) e o tempo de permanência em Apoio Unipodal (30,00 ± 13,04 s) quando comparado a outros estudos envolvendo praticantes de atividade física e idosos não ativos que sofreram ou não quedas. Os resultados goniométricos encontrados na literatura apresentam divergência além de serem escassos dificultando a comparação com os do presente estudo. Portanto, o efeito crônico da hidroginástica não influencia a relação entre controle postural e amplitude articular de movimento embora pareça promover melhora no equilíbrio corporal em idosas.

Published: May 2023

A field experiment was conducted during 2020-21 at agroforestry farm of Faculty of Forestry in Birsa Agricultural University, Ranchi, Jharkhand, India with two years old Gamhar (Gmelina arborea) trees intercropped with leguminous crops viz., Pigeon pea (Cajanus cajan), Cowpea (Vigna unguiculata) and Urad (Vigna mungo) under Gamhar based agroforestry system to estimate the litterfall produced by Gamhar tree and respective nutrient return associated with litter decomposition. The experiment was laid out in Randomized Block Design (RBD) with four treatment combinations viz., T1= G. arborea + C. cajan, T2= G. arborea + V. unguiculata, T3= G. arborea + V. mungo, T4= Sole G. arborea (control) which were replicated three times and statistically analyzed. The results indicate that the maximum litter from litter trap (342 kg ha-1) was found in month of February, the total annual litterfall was estimated to be 865 kg ha-1. Litter biomass was found to be high in G. arborea + C. cajan (892 kg ha-1), even the nutrient release pattern was found to be highest in G. arborea + C. cajan viz. 13.38 kg ha-1, 1.34 kg ha-1 and 10.08 kg ha-1 of total N, P and K respectively. The study concludes that Gamhar based agroforestry system has a good potential for nutrient cycling, particularly when Gamhar is intercropped with pigeon pea, it showed a positive influence on the nutrient release pattern.

Published: May 2023

The present study was undertaken in North Western Zone of Tamil Nadu, to analyze the factors determining the agro-forestry and problems faced by them in adoption of agroforestry practices. Primary data were collected through a pre-structured questionnaire from a sample of 300 respondents who were selected using multi-stage random sampling technique. Data analysis was done by using simple percentages, Ordinary Least Squares (OLS) multiple regression analysis, perception index and weighted score method. Most of the farmers in study area have positive perception towards adoption of agroforestry practices. The goal of this study was to determine the characteristics that influence the adoption of agroforestry by small and marginal farmers. Crop diversification, Increasing soil fertility, Improve soil and water conservation, Long time taken to get income from forestry, high returns and Reduce chances of crop failure were the major motivational factor, whereas small landholding size, lack of awareness and poor knowledge, poor market accessibility, lack of subsidy, credit facility, lack of good quality planting material and longer gestation period of trees were the major problems faced by the farmers in the study area. Thus, study suggested that farmers can be encouraged to practice agroforestry through improved mobilizing farmers to join groups, improving the quality and coverage of extension services, consideration of gender issues and intensifying agro forestry training among farmers with low levels of education groups and distribution of quality planting material to farmers.

Apple is a widely consumed fruit that is accessible throughout the year and is high in phytochemicals. The current study's major goal is to use computational methodologies to discover new anti-cancer medication candidates from plants. The ligands of the plant malus pumila were docked with protein EGFR (PDB ID:1M17) to predict novel potential inhibitors that could be employed as anticancer medicines for breast cancer. Breast cancer is a complex disease with no known single cause that continues to be a global killer and the leading cause of cancer-related death in women. One of the first key targets of these emerging anticancer drugs was the epidermal growth factor receptor (EGFR).The physicochemical, pharmacokinetic, and drug-like properties help in the selection of the best compound for breast cancer treatment. Furthermore, a substantial study suggests that phytochemicals, which are plant secondary compounds have oncopreventive Properties.

RECLAMATION OF PESTICIDES CONTAMINATED SOIL AND WATER USING BIOCHAR: A REVIEW ON ADSORPTION POTENTIAL OF BIOCHAR
Authors: Ashesh Akriti , Linthoingambi Devi Ningombam
Published: May 2023

The application of agrochemicals into the environmental matrix has sluggishly degraded the quality of their original form. Pesticide consumption in the agricultural sector has been used for the quantity production of crops however, now considered as a culprit for the quality crops. Lands that once provided ample crops of good quality are now facing a case of severe damage impacting their crop quality. The prime need is to reclaim these contaminated matrices. For the same, an eco-friendly approach should be adopted. One such approach is the application of biochar for pesticide sorption. Biochar is a carbon-rich, stabilized product acquired when biomass undergoes pyrolysis at 200-650˚C. It is known for sequestration ability and mitigation of environmental contaminants. Its properties (surface area, pore size, ash contents, and functional groups) determine the potential for sorption. Biochar when modified is most effective for the sorption mechanism. For instance, rice straw biochar when treated with phosphoric acid (T-RSBC) showed stronger adsorption capacity for sorption in waste water effluent. Corn straw when doped with phosphorus functional groups was highly effective for adsorption of triazine pesticide from water. Other biochar that could remove pesticides are corn cob and corn starch. Activated coconut shell biochar showed the highest adsorption capacity for diazinon removal from water than other modified coconut shell biochar. Plant biochar (pine needle, oak wood, corn stover) having a high content of lignin have better properties such as large surface areas (112-642 m g ) and macropores (0.06- 1.90 cm g ) that increase the sorption capacity of pesticides in soils than animal and cellulose-based biochar. This review paper aims to evaluate the role of biochar in the sorption of pesticides from soil and water.

ANALYZING THE IMPACT OF BUILT UP AND GREEN SPACES ON LANDSURFACE TEMPERATURE WITH SATELLITE IMAGES IN JALANDHAR SMART CITY
Authors: Prashar Yukti , Sharma Reenu , Kumar Sumit , Hassan Syed Shabih , Pateriya Brijendra
Published: May 2023

Land use in developing nations is shifting as a result of rapid urbanisation. The ecosystem is being harmed by the unplanned, urban development of cities. Utilizing data from Landsat, the present research examined the spatiotemporal urban growth in Jalandhar City and its impact on variations in land surface temperature (LST). The results indicate that urban regions have increased while urban green spaces have shrunk (UGS). UGS and LST have been found to be inversely correlated. Where there was a low percentage of urban areas and a high percentage of accessible green spaces, it was observed that the LST decreased. The link between spectral variability and changes in vegetation growth rate was studied using the NDVI (Normalized Difference Vegetation Index). It works on tracking the growth of green vegetation and spotting variations in the amount of greenery. Where NDVI value was low, the scatter plots indicate higher surface temperatures. The dense urban regions with little available vegetation cover were linked to the low NDVI number and the NDVI is negative in the urban area of Jalandhar. High NDVI values indicate regions with dense vegetation and low surface temperatures. The research findings of present study could be applied to urban administration, planning, management and research projects.

Influence of Factors on the Formation of Reputation in Insurance Companies
Authors: Gerwald Frank
Published: May 2023

The aim of this work is to identify important factors that insurance companies consider important for their reputation and at the same time to assess their weighting. Based on the results of an extensive literature review, the six factors that are held responsible for the formation of reputation were derived. These factors served as the basis for structured expert interviews, which were conducted with experts from the insurance industry following the literature research. The evaluation of the interviews shows that, due to the regulatory nature of the insurance industry, special conditions apply here for the formation of reputation. In particular, the area of services should be considered separately from the product factor, as this is where insurers have the best opportunities to create their own profile and differentiate themselves from the competition. The survey also shows that the responsible handling of corporate values and the emotional appeal to stakeholders are regarded as important factors by the experts. While the interviewees indicated that they ascribe growing importance to social media, at the same time there is still room for improvement in insurers' use of these channels.

Published: May 2023

In modern era of globalization, we face every day to new business models, technologies and way of enterprises achieve their revenues and gain profits. Under these conditions is quite harder to tax internationally operating businesses when we realize that actual network created of bilateral and multilateral treaties in not so perfect as we would assume. From these facts arises the research question. Is actual network of bilateral tax treaties perfect? If no, where the weak parts are? And finally, and most importantly, how can we measure it? In our research paper we analyze which tools of social network analysis can be used to measure and examine nature of bilateral tax treaties network. By understanding answer to this research question, in future we would be able to fully use all the SNA tools, that are most suitable for network of bilateral tax treaties and treaties like them. Furthermore, we can predict which tools are on the other hand not suitable for this type of network.

Published: May 2023

To compare the life cycle emissions from EV (electric vehicle) and ICE (internal combustion engine) car is very important task. Results will influence general perception of EV potential buyers as well as policy makers. The methodologies to properly calculate LCA (life cycle assessment) emissions for EV and ICE are subject of development and their applications differ across the studies. Some of the suggestions for LCA methodologies adjustments as suggested by this article includes novum, other (like battery recycling, battery second life, longer EV life span) occurs already today in different LCA analyses, however there is still rather a big diversity of the ways of their application. The suggestions have a methodological nature, should open wider debate related to LCA methodologies development and possibly might inspirate future research work in their application. By working on this paper, the author finds out that due to the methodological robustness of LCA, country specific inputs (mainly for the energy mix), diversity of LCA applications, lacking worldwide precise standard on LCA methodology, whenever you read any outcomes related to LCA EV or ICE emissions, the reader has to go rather deeply to how the LCA was applied by author/s, in which environment, what sort of datasets were used and only after thorough assessment of the author approach, respective results can be used for further decision making.

Published: May 2023

The aim of this article is to measure the impact of the fluctuations in the real exchange rate of the Syrian pound on the key macroeconomic indicators of the Syrian economy during the period 1961- 2020 to analyze the role of the real exchange rate in achieving economic stability. Since 2011, the Syrian economy suffered from a devastating war that effected all economic and social aspects of business activities leading to high fluctuations and instability of the macroeconomic ecosystem. During the first 40 years of study, the political stability in Syria has not been translated into economic stability on at the macroeconomic level. Moreover, during the last 11 years, the political instability has worsened the economic situation. To achieve the objective of this study, we applied autoregressive model and simple regression model on a various macroeconomic variables including the real exchange rate. The results show that the real exchange rate has a significant positive impact on the balance of payment, inflation, GDP gap, and negative impact on Real GDP, unemployment rate, monetary supply (M2).
Low Risk Anomaly and Coskewness: Evidence from Europe
Authors: Rašiová Barbara
Published: May 2023

Empirical findings that less risky stocks consistently outperform the riskier ones have motivated a great number of studies on the low risk anomaly. This paper aims to explain it away by controlling for coskewness of stock returns with the market return on the European stock market represented by constituents of the S&P 350 Index. Stocks are double sorted on coskewness and beta volatility into 2x5 quintile portfolios, and their excess returns are subsequently regressed on the Fama-French three and five factor models separately for both coskewness categories. In the low coskewness category, a persistent, highly significant low risk anomaly is identified. As the coskewness increases, the low risk anomaly dramatically decreases and loses statistical significance. As a result, in the high coskewness category, less risky portfolios no longer consistently outperform the riskier ones. Results demonstrate that accounting for coskewness in the model remarkably decreases the profitability of low risk and betting-against-beta strategies in European data.

Authors: Soldo Lana , Schagerl Christopher
Published: May 2023

Agricultural commodities prices skyrocketed during the first quarter of 2022, mainly driven by the escalation of the situation between the Russian Federation and Ukraine, but also by extreme climate conditions in certain geographies and protectionist measures introduced by governments to protect domestic supplies. Within this paper the authors would like to provide an overview of the biggest producers and exporters of the selected agricultural commodities, being wheat, corn, and sunflower seeds and oil, and their price development in 2022. For all of them, the two conflicting countries, the Russian Federation and Ukraine, play an important role in world production and export. The production and export volumes should be analyzed along with the price developments in the first months of 2022. As the products are traded on the commodity market the comparison is based on the traded prices.
Dedoles: Behind the Growth Ambitions
Authors: Bednárová Veronika
Published: May 2023

The growth ambitions are elementary for business success but taken too far, the growth ambitions could also lead to company failure. The growth ambitions are necessary for the beginning of the growth process, they are also the force that keeps the morale growing. The growth ambitions alone are not enough. Corresponding to the ambitions there should be a meticulously prepared business growth plan. Every managerial decision should be strategically considered, each internal process should change suitably to the speed of growth. There are also external macroeconomic factors that the company should deal with. The main aim of the paper is to analyze the growth of the company Dedoles as an example of a fast-growing company with an ambitious entrepreneur. Dedoles was the company that achieved rapid growth, but now is coping with problems connected to huge growth ambitions without appropriate managerial decisions and consideration of external factors. The paper analyzes the causes of the situation, and the consequences of the managerial growth decisions and presents the company's solution to the situation of not achieving the planned growth by Dedoles.
Landfilling as a Significant Environmental Burden in Slovakia
Authors: Staško Martin
Published: May 2023

In order to improve the state of the environment, it is essential, that the issue of landfilling, as a significant environmental burden, becomes a priority, as well as activities leading to the removal of existing landfills and the prevention of new ones. The presented paper deals with landfilling as a significant environmental burden in Slovakia, in which we analyze the amount of waste produced in Slovakia, the forms of its management with a closer focus on the rate of landfilling of municipal waste for the period 2005 to 2020. The paper uses descriptive statistics as research methods, specifically frequencies, percentages, minimum and maximum values, dispersion and averages. In the results, the paper states, that the amount of generated waste (without municipal waste) in Slovakia increased by approximately 14,5 % during the period 2005 – 2019. By analyzing the rate of landfilling, it was found, that it has been one of the dominant ways of dealing with municipal waste in Slovakia for several years, despite the fact, that its rate decreased by almost 30 % from 2005 to 2020. It is necessary, that the issue of landfilling becomes a priority in the future, and it is also necessary to develop activities leading to the removal of existing landfills and the prevention of the creation of new ones. In the coming years, Slovakia must proceed with significant structural changes in waste management. One of the possible solutions is to withdraw from the prevailing landfilling and transform to other forms of disposal of waste.
Behavioural Economy Perspective on Decision-Making of the Location of the Company
Authors: Súkeník Norbert , Jankelová Nadežda
Published: May 2023

The paper brings insights on business localization mainly from de-scriptive theories, which, in contrast to the ideal state, study the reasoning of de-cision makers as human beings. These are inherently fallible and subject to a large variety of factors that normative theories are not yet able to encompass. The article builds on previous work, published under the title Deciding on the location of the company, where the authors describe classical theories while also placing the topic in the context of behavioral economics research. This paper takes a be-havioral science perspective only and discusses in more detail selected behavioral theories and their potential contributions to the understanding of firm location decision-making processes.
Attention and Volatility in Renewable Energy Stocks
Authors: Tabaček Jakub
Published: May 2023

Under the Efficient Market Hypothesis stock prices should reflect only the fundamental information relevant to the company in question. If other, such as behavioural factors affect the stock price, then this discrepancy should be resolved by the means of arbitrage traders. In our study we look at the effect of retail trader attention on the volatility of renewable energy companies’ stocks. We find that attention, measured by Google Trends, is a good in-sample predictor of next day volatility for a given company’s stock. We later try to explore this anomaly in an out-of-sample study.

Authors: Teplanová Patrícia , Závodný Michal
Published: May 2023

There are many reasons why an insured person lapses (cancels) his policy. Lapse risk is one of the main risks, which is also defined in Directive Solvency II. Lapse analysis can be performed by various statistical methods. In this paper, we illustrate the possibility of using survival analysis to calculate the lapse ratio. Survival analysis does not have to be used only in medical research but nowadays finds application also in economics e.g., actuarial science. We focus on the Kaplan-Meier estimator, the most used method of modeling survival times. In practice, not every insurance policy has to lapse, so survival times from these policies should be right-censored. The Kaplan-Meier method allows to include these censored observations in the model. We use R programming language to calculate Kaplan-Meier estimation for survival times and to plot survival functions. Since the Kaplan-Meier model is univariate model, we focus on the impact of sex on insurance policy lapses.

This paper investigates the long-term causal effects of receiving an ERC grant on researcher productivity, excellence and the ability to obtain additional research funding up to nine years after grant assignment. We use data on the universe of ERC applicants between 2007 and 2013 and information on their complete publication histories from the Scopus database. For identification, we first exploit the assignment rule based on rankings, comparing the outcomes of the winning and non-winning applicants in a regression discontinuity design (RDD). We fail to find any statistically significant effect on research productivity and quality, which suggests that receiving an ERC grant does not make a difference in terms of scientific impact for researchers with a ranking position close to the threshold. Since RDDs help identify a local effect, we also conduct a difference-in-differences (DID) analysis using the time series of bibliometric indicators available, which allows us to estimate the effect on a wider population of winning and non-winning applicants. By contrast with the RDD results, DID estimates show that obtaining an ERC grant leads to positive long-term effects on scientific productivity, impact and the capacity to attract other EU funds in the fields of Chemistry, Universe and Earth Sciences, Institutions and Behaviours, Human Mind Studies and Medicine. Further analysis of heterogeneous effects leads us conclude that the positive results obtained with DID seem to be driven by the top-ranked applicants in these fields.

The first incidence of the COVID-19 pandemic, which is spreading quickly, was found in Wuhan, Hubei Province, China, in December 2019. On March 11, 2020, the WHO proclaimed COVID-19 to be a pandemic due to the rapid increase in cases both in China and around the world. The disease, which mostly damages the lung parenchyma, is spread through respiratory droplets produced when infected individuals cough or sneeze. Patients with COVID-19 can experience a wide range of clinical symptoms, from asymptomatic infections to life-threatening disease. Although COVID-19 patients are most frequently affected by respiratory involvement, the virus can also harm other organ systems. The development of extra-pulmonary symptoms affecting the gastrointestinal, cardiovascular, hematological, renal, musculoskeletal, and endocrine systems is explained by the systemic inflammation caused by the disease in combination with multisystem expression of Angiotensin Converting Enzyme 2 (ACE2), a receptor that permits viral entry into cells. In this article, we've covered the wide body of literature on COVID-19 that covers a variety of clinical presentations according on the organ system affected as well as clinical presentations in certain populations like kids, pregnant women, and patients with impaired immune systems. Additionally, we briefly touched on the treatment of COVID-19. Understanding the various clinical manifestations can aid doctors in correctly diagnosing COVID-19 early on and implementing the necessary countermeasures to stop the disease's progress.
SALPINGECTOMY AT THE TIME OF CESAREAN DELIVERY: A SYSTEMATIC REVIEW
Authors: Ratu Alicia Dea Nabila
Published: May 2023

Candidates for tubal sterilisation include women who have finished having children and who are looking for a method of birth control that is both highly effective and permanent. It is possible for it to be carried out at any point during a woman's menstrual cycle, as well as right after a child is born or an abortion is performed. Hysteroscopy, laparoscopy, or even a mini-laparotomy might be performed instead. It is important to have a conversation about the danger of regret as well as the characteristics that increase the likelihood of regret, such as a young age at the time of sterilization (less than 30 years), a lower parity, sterilization administered in the immediate postpartum period, divorce or remarriage following sterilization, and being poor or of Hispanic origin. It would appear that being a young adult at the time of the sterilization is the most significant indicator of regret. It is extremely important to keep in mind that this does not provide full protection. According to the findings of the CREST study, the failure rate across all procedures was 18.5 out of every 1000 procedures over the course of a 10-year period. Even in the event that a cesarean birth is performed unexpectedly, a mother request for postpartum permanent contraception in the form of bilateral total salpingectomy during cesarean delivery may be a procedure that is both safe and practicable.

The General Data Protection Law – LGPD strengthened the protection of personal information at the national level and equated it with international legal discipline. Inspired by the General Data Protection Regulation – GDPR, the LGPD establishes the principle of purpose as one of the keys to understanding it. In the search to better reflect on the performance of the principle of purpose in the context of the General Data Protection Law – LGPD, through a qualitative and revisional approach, this article aimed to present some reflections on the importance of the principle of purpose in the application of the LGPD. From the theory of the principles of Humberto Ávila it was found that the principle of purpose goes beyond the boundaries of norm of orientation to constitute an instrument of delimitation and action in the search for the protection of personal data in the context of contemporary life, directing the LGPD to new horizons regarding the relational process of personal rights of a fundamental nature and the purpose as a principle.
Single Step Ahead Assessment of Solar Irradiation Using Ann Model Based on Various Combination Of Meterological Parameters
Authors: Gupta Anuj
Published: May 2023

Solar energy is a valuable resource on earth but the availability of solar resources relies on meteorological variables. In this paper, forecasting models using the artificial neural network are developed by changing the input meteorological variables from five to seven. The two years data are used to train the model whereas the testing is performed using one year data on different seasons following single step ahead. The input parameters are relative humidity, pressure, temperature, solar zenith angle, wind speed, wind direction and perceptible water. Three artificial neural network models (ANN-I5, ANN-I6, ANN-I7) are developed to estimate the global horizontal irradiation and performance of all models are measured on the basis of Mean Absolute Percentage Error (MAPE), Relative Root Mean Square Error (RRMSE) and Correlation Coefficient (R2). Result indicates that ANN-I7 shown better performance as comparison to other developed models. The average MAPE and RRMSE of ANN models such as ANN-I7, ANN-I6,  ANN-I5 are 14.52%, 16.53%, 18.97% and 20.74%, 22.28%, 24.43% respectively. The ANN-I7 haiving an input meteorological parameters relative humidity, pressure, temperature, solar zenith angle, wind speed, wind direction and perceptible water showed good accuracy as comparison to other two developed models. This study indicates that accuracy of solar irradiation forecasting depends on meteorological parameters.

Published: May 2023

In recent years, increasingly more soils are getting contaminated with organic and inorganic toxins globally due to waste emissions. Among inorganic pollutants, heavy metal like chromium (Cr) is alarming to our environment, even though its environmental management is also ignored. As a result, Cr accumulates in plant tissues at toxic concentrations end up in the food chain. Therefore, pot experiment was conducted to investigate the effects of biochar and modified biochar application on the properties of Cr polluted soils and interaction of Cr with other soil nutrients. Two different biochar viz. rice stubble and saw dust were slow pyrolyzed (450 ± 50ºC) and modified with1M KOH. All biochars were applied at a rate of 20 t ha-1 on soils artificially polluted with Cr at the levels of 0, 100, 200 and 300 µg g-1. The biochars and modified biochars had significant effects (P<0.05) on available K, P, CEC, EC, and N of incubated soils. Therefore, it has convincing evidence that application of biochar and modified biochar is very imperative to improve soil health, ameliorate Cr polluted soils, reduce the amount of carbon produced due to biomass burning and thereby enhances plant growth.
