Online Political Communication of Youth from Russian Megapolises
Authors: Popova Olga V.
Published: June 2021

Youth remains one of the most active groups of Internet users. The purpose of the study is to identify the features of the use of various social networks, Internet channels and messengers in online political communication of young people from Russian megacities. The research paper presents the results of an online survey of this socio-demographic group conducted in January 2021 among roughly 1700 respondents from 17 Russian megacities as well as the results of an expert survey dated January 2021, namely, non-standardized expert interviews with 21 experts, including scholars, political technologists, government officials, members of political organizations and civil activists. Every fourth young respondent spends over 8 hours in the Internet space daily with about 43% of all young people spending from 4 to 8 hours. Social networks such as VKontakte (91.4%), Instagram (70.6%), YouTube Internet channel (74.9%), WhatsApp (66.4%) and Telegram (59.2%) are most in demand. The interest in Tik Tok is gradually growing (38.8%). Experts believe that the promising channel of online political communication with the aim of online political mobilization is the social network Clubhouse, which allows group voice chats and a strict selection of group members, but does not allow direct recording. Only every fourth representative of young people shows a high interest in the political situation. About 45% use Emoji to assess posts on a political topic, but only every fourth respondent gives comments and discusses political problems. Every fourth representative of young people does not take any political actions in the online space.
“Are You in Your Body?!”. The Study of Biopolitical Interface Design
Authors: Lenkevich Alexander S.
Published: June 2021

The article considers biopolitical design of interfaces in terms of computer games: the player's body is constructed with the help of a variety of technical instances that support gameplay (for instance, gamepads, haptic controllers, virtual reality devices). Through the interaction with interfaces, the new patterns of sensuality are formed, namely, the new forms of tactile communication with media. The article demonstrates the distinction between the representation of biopolitical processes in games (for instance, in Plague. Inc. and Bio. Inc.) and the process of incorporating biopolitical procedures into technical gaming devices, and through them into our bodies and lifestyle. The setting and narratives of games often tend to rely on biopolitical images. However, the processes that take place in our body during the game are more important than those that are presented on the screen: the new controllers increasingly take into account the physical state of the player in order to regulate the level of difficulty, promising not only entertainment but also care. The article raises the question of what the body feels and does not feel when it is included into the game, since the existing interfaces and controllers allow us to simulate a complex perceptual experience which includes not only audiovisual elements, but also touch, smell and so forth. After all, the (self-) control practices embedded in game controllers allow us to view them as technical dispositives through which we master the bodies of the future. The author of the article proposes the concept of a “touch-image" which captures a new dimension of hi-tech sensibility.

Authors: Cortat Lucas  Henrique
Published: June 2021

O presente estudo avalia o efeito da dieta sobre a reprodução e o desenvolvimento dos cladóceros Ceriodaphnia dubia e Simocephalus iheringi, cultivados em laboratório. Indivíduos adultos foram distribuídos por seis frascos de 1 L (10 indivíduos por frasco), divididos em dois lotes iguais. Um lote foi tratado com dieta mista de microalgas (Ankistrodesmus sp., Dictyosphaerium sp. e Volvox sp.) cultivadas em laboratório e o outro lote foi tratado com dieta unialgal (Volvox sp.). O período experimental foi de 21 dias, com fotoperíodo de 8 h e temperatura entre 26 e 28 ºC. A quantidade fornecida foi de 20 mL da cultura algal com a densidade de 1,01 x 106 células mL-1, a cada quatro dias. Foram feitas duas contagens da população (sete e 14 dias), em câmara de Sedgwick-Rafter, com aumento de 40 X, utilizando-se subamostras de 1 mL. Para cada tratamento foi verificada a fecundidade média, o tempo de desenvolvimento embrionário, o tempo de desenvolvimento pós-embrionário, a idade da primeira reprodução (IPR), o tempo de vida (TV), a taxa intrínseca de crescimento e o tempo de duplicação da população. Para as duas espécies estudadas, a fecundidade média e o crescimento populacional foram maiores, com a dieta mista. Esta proporcionou maior tempo de vida para Ceridaphnia dubia e menor tempo de vida para Simocephalus iheringi, em relação à dieta unialgal. A fecundidade foi afetada pela dieta, pelo tamanho das fêmeas (Ceridaphnia dubia) e pelo tamanho da população (Simocephalus iheringi). Os melhores resultados, para ambas as espécies, foram obtidos com a dieta mista.

The article considers transformation of the Egyptian foreign policy towards the Crusader States in the first years after mamluks’ coming to power. Due to different reasons the previous academic papersconsidered this policy to sufficient extent only after the beginning of the reign of al-Zahir Baybars (1260-1277) (this is primarily due to the specifics of the sources, as well as the low interest of theworld science to seemingly minor events that having a purely regional dimension). The aim of the article is to identify the reasons and nature of this transformation. The object of the research is theforeign policy of the first mamluks before al-Zahir Baybars’s reign. Mongol invasion, the previous attempt of Louis IX to attack Cairo, as well as the conflict between Genoa and Venice resulted inmamluks’ decision to eliminate completely the Crusader States in the Middle East.

COVID-19 has proliferated personage suffering around the world. The virus is contagious medically and economically as well. The study's main aim is to examine the failure of the social protection system caused by the COVID-19 pandemic. Three major dimensions of the social protection system have been addressed in this research—a shock to the labor market, health emergency, and massive change in energy usage. Covid pandemic had cost the world economy more than $2 trillion. The labor market is badly affected significantly; workers engaged in the informal economy. The Director-General (WHO) has declared the COVID-19 pandemic as a public health emergency of international concern. It is one of the highest levels of alarm by WHO in history. Global Energy Review 2020 shows that those complete lockdowns have a 25% decline in the energy demand per week.

Conclusively, it is examined that the coronavirus pandemic has brought a worldwide failure of social protection system required a comprehensive policy and a firmed leadership to stand against the outbreak.
LIFE IMPRISONMENT AND PAROLE IN SERBIA – (UN)INTENTIONALLY MISSED OPPORTUNITY
Authors: Kolaković-Bojović Milica
Published: June 2021

Triggered by the cruel rape and murder of a 15-year-old girl in July 2014, the public campaign was launched in order to change penal policy for a sexual violence committed against children in Serbia. Widely supported by general public, but strongly disputed by legal experts and professionals, amendments to the Criminal Code have been adopted in May 2019 introducing the life sentence without parole for the most serious crimes committed against children. This influenced the decision of the author to further explore how this public policy action fits to the relevant international standards, but also to the framework built based on the ECtHR interpretation of the Art. 3 of the ECHR in terms of the life prison. Aware of the current lack of public debate and the initiatives to improve relevant provisions of the Criminal Code, this paper shads a light on the gaps in human rights protection, especially in terms of the rehabilitation and reintegration of prisoners as the undetachable element of a purpose of punishing.

There are three kinds of inheritance law in Indonesia, namely Islamic inheritance, Customary inheritance and BW inheritance. The scope of this writing is limited to customary inheritance law. The parts of customary law have a big influence on customary inheritance law and vice versa. Customary inheritance law has its own characteristics and characteristics that are unique to Indonesia, which is different from Islamic law and western law (BW). Because the difference lies in the natural background of the Indonesian people who have the philosophy of Pancasila with a society that is Bhinneka Tunggal Ika. The inheritance law that exists and applies in Indonesia to date is still not in the form of legal unification. The purpose of this study is to analyze the inheritance system according to the customary inheritance law related to the kinship system in Indonesia.The type of research used in this research is normative juridical research, namely research on legal systematic is research conducted on primary and secondary legal materials, the terms of reference used are the basic definitions contained in the legal system. The approach used is a conceptual approach, a statute approach and a case approach. Types of Legal Materials are primary legal materials and secondary legal materialsThe results of this study indicate that the inheritance system according to the Adat Inheritance Law does not refer to the kinship system of the customary law community. Customary law communities whose system of collective inheritance can occur are parental kinship systems. Heritage assets related to inheritance must be distinguished from the origin of the assets, because they are related to the kinship system that exists in the local customary law community, whether parental, patrilineal or matrilineal, because not all inheritance can be divided individually.

One of the aspects that must be of concern in electronic transaction activities is the aspect of personal data protection so that the personal data of service users is maintained. One of the principles that must be observed by Electronic System Operators in protecting personal data is the principle of prudence. This paper will examine the principles of prudence in the operation of electronic systems in efforts to protect personal data in Indonesia by using normative research methods. In general, it can be seen that the precautionary principle is not explicitly regulated in the formulation of laws and regulations related to Electronic Information and Transactions or Personal Data Protection, but the provisions of the articles therein contain provisions regarding the principle of prudence. The application of the precautionary principle is carried out with the active efforts of electronic system administrators as the party that manages the personal data of service users to ensure data confidentiality and the security of their electronic systems with all efforts to prevent the system from being compromised by third parties. The legal consequence is that if there is a leak of personal data, the electronic system operator is obliged to be responsible civilian by paying compensation on the basis of a lawsuit by the owner of the personal data who has experienced data leakage and / or material or immaterial loss
Külföldi munkavállalás, foglalkozásváltás és szakmaelhagyás
Authors: Hárs Ágnes , Simon Dávid
Published: June 2021

Az útnak indulók leggyakrabban a magasabb bér, a jobb munkafeltételek vagy a kellemesebb munkakörnyezet reményében döntenek a külföldi munkavállalás mellett. A migrációs modellekben feltételezett képet személyes motivációk árnyalják és teszik változatossá. A remélt előnyök és nyereségek, a haszonmaximalizálás mellett az elhatározás sokszor áldozattal, személyes veszteséggel jár. Aki külföldön vállal munkát, gyakran a hazaitól eltérő tevékenységet végez. A szakmaelhagyás, foglalkozásváltás lehet ígéret, de veszteséget is okozhat. Cikkünk a migrációnak ezt a szeletét, a külföldre költözött és ott munkát vállaló magyarok foglalkozásváltásának, pályaelhagyásának a mintázatát és motivációját vizsgálja.
A közép-ázsiai köztársaságok járványkezelése és az orosz-kínai vakcinaversengés kérdése a régióban
Authors: Gyene Pál
Published: June 2021

A közép-ázsiai térségre a Szovjetunió széthullását követően a sajtóban, csakúgy, mint a szakirodalomban, sokszor hivatkoztak a nagyhatalmak – mindenekelőtt Oroszország és Kína – között újjáéledő geopolitikai versengés, a „Nagy Játszma” arénájaként. Noha a kilencvenes években a régió sokkal inkább egyfajta nagyhatalmi vákuumba került és geostratégiai magárahagyatottságtól szenvedett. Az ezt követő évtizedekben pedig Kína és Oroszország között számos területen inkább az együttműködés, illetve egyfajta komplementer reláció, mintsem a versengés volt megfigyelhető a posztszovjet közép-ázsiai térség kapcsán. Mindenesetre kijelenthető, hogy a 2020-ban kezdődött koronavírus-világjárvány nyomán az esetleges regionális hegemóniatörekvések eddigi fő vetületei (katonai, gazdasági, kulturális) egy újabb dimenzióval, a vakcinapolitikával bővültek. Oroszország és Kína a vakcina-kutatás-fejlesztésre, -gyártásra és -exportra egyaránt a regionális, illetve globális nagyhatalmi politika és presztízs eszközeként tekint. Tanulmányunkban a közép-ázsiai köztársaságok járványkezelési stratégiáinak rövid bemutatása mellett mindenekelőtt annak a kérdésnek a megválaszolására teszünk kísérletet, hogy Közép-Ázsiában lehet-e orosz–kínai vakcinaversengésről beszélni, vagy ezen a téren is inkább a kooperáció és a komplementaritás dominál a szóban forgó regionális nagyhatalmak között.
Plant Growth-promoting Microorganisms Isolated from Plants as Potential Antimicrobial Producers: A Review
Authors: Marzaini Bazilah , Mohd-Aris Aslizah
Published: June 2021

The agricultural industry worldwide faces challenges in the struggle against plant diseases. In efforts to increase agricultural intensities, the dependency on agrochemicals for crop protection has become significantly high. Moreover, the increasing use of agrochemical-based products has resulted in multidrug-resistant pathogens and environmental pollution. This paper reviews the biocontrol capacity of plant growth-promoting microorganisms (PGPMs) originating from plants towards plant pathogens. The current trend in discovering new compounds has shown antimicrobial activity gaining immense interest due to its vast potential. On a related note, PGPMs are an aspect of that research interest that can be further explored as antimicrobial producers. In this work, we also covered the types of biocontrol mechanisms pertaining to PGPMs as well as their roles in biocontrol activity. A biocontrol approach exploits disease-suppressive microorganisms to improve plant health by controlling related pathogens. The understanding of these microorganisms and mechanisms of pathogen antagonismare primary factors in ensuring improvement for future applications. Inevitably, there is indeed room for rigorous expansion with respect to PGPMs in the future of agriculture.
Dioscorea alata as Alternative Culture Media for Fungal Cultivation and Biomass Production
Authors: Sawiphak Suwapha , Wongjiratthiti Aroon , Saengprasan Chanankarn
Published: June 2021

Dioscorea alata (purple yam) is a tuber crop that contains plenty of nutrients. It is widely cultivated in Thailand, but it is underutilized. In this study, the suitability of purple yam to replace potato dextrose media for fungal growth was investigated. Mushrooms and molds were grown on purple yam dextrose agar (PYDA), whereas yeasts were cultured in purple yam dextrose broth (PYDB). Response surface methodology (RSM) with Box-Behnken design (BBD) was used to optimize the culture conditions for Saccharomyces cerevisiae biomass production. The growth profile of S. cerevisiae in PYDB under optimized culture conditions was also studied. All test mushrooms and molds recorded the highest colony diameter and mycelial dry weight on PYDA containing 40% purple yam. Similar to mushrooms and molds, yeasts in PYDB with 40% purple yam showed the highest number of cells. The growth of fungi on purple yam dextrose media was significantly higher than those on potato dextrose media under standard conditions. The optimal conditions from the RSM results for the biomass production of S. cerevisiae in PYDB were purple yam concentration of 49.61%, dextrose concentration of 4.87%, pH value of 5.74, and inoculum size of 7.00%. The biomass of S. cerevisiae in PYDB under the optimal conditions obtained from the results of the optimization by RSM was thirty times higher than S. cerevisiae biomass in potato dextrose broth under standard conditions. Our results suggest that purple yam could be an alternative to potato dextrose media for fungal cultivation.
Foraging Behaviour of Heterotrigona itama (Apidae: Meliponini) in Residential Areas
Authors: Benedick Suzan , Gansau Jualang Azlan , Ahmad Abdul Hamid
Published: June 2021

This study aims to investigate the foraging behaviour of Heterotrigona itama in exploiting food resources at a residential area, and the viability of this species to adapt to urban microclimatic conditions. Heterotrigona itama prefers to forage at areas closer to their nesting site, where diverse food sources are found. The marked bees of H. itama prefer to forage on various resources available at a 500-metre radius from the house yard. The obtained results indicate that the active foraging pattern of H. itama is negatively correlated to the time phases of a day (p < 0.05). This phenomenon was contributed by the three peaks of foraging hours, which reached a peak in the early morning (6:30 to 8:00 a.m.), moderately peaked towards the evening (2:30 to 3:30 p.m.), and was greatest towards the afternoon (10:30 a.m. to 12:00 p.m.). The ambient temperature and relative humidity were not the primary factors influencing the average number of foragers exiting from and returning to the hives (temperature, p > 0.05; and humidity, p > 0.05). There was a difference between the varieties of content resources collected by the bees (p < 0.05). The nectar or water sources was the highest material (51.39%) that was brought back to the hive by foragers, followed by resin (34.73%) and pollen (13.87%). There was a significant difference in foraging time phases by returning foragers for collecting resin (p < 0.05) and nectar or water (p < 0.02), but there was no significant difference in foraging time phases found for pollen (p > 0.05). We concluded from the results that H. itama is able to withstand urban microclimate conditions, and successfully incorporated pollen, nectar or water, and resin obtained from floral and non-floral resources into their diet.

Соңғы жылдары медицина, биология және ветеринария ғылымдары салаларында эмбрионды трансплантациялау әдісін кеңінен қолдануда. Донорлар мен реципиенттердің физиологиялық жағдайын гормональды препараттарды қолдану арқылы реттеу жүргізіледі. Қазақстанда қой шаруашылығы ауыл шаруашылығының дәстүрлі саласы болып табылады. Айта кету керек, өнімділік қасиеттері бойынша генетикалық іріктеуден басқа, қой шаруашылығын жақсартудың маңызды факторы репродуктивті тиімділік болып табылады. Қой мен ешкілердің бақыланатын өсімін молайту үшін қолдан ұрықтандыру, эмбриондарды трансплантациялау, сондай-ақ эмбриондарды in vitro телу технологиялары пайдаланылады. Сонымен қатар, клондау және трансгенез сияқты басқа биотехнологияларды дамыту үшін ооциттік және эмбриональды әдістер қажет. Алайда, ұсақ малдың in vitro эмбриондарын өсіру эмбриондарды трансплантациялаудың ең танымал бағыты болса да, in vivo эмбриондарын қолдану арқылы көбею ең сәтті болып табылады.. Сондықтан асыл тұқымды жануарлардың санын көбейту кезінде эмбриондарды трансплантациялаудың in vivo әдістеріне маңызды рөл беріледі. Бұл жағдайда жоғары өнімді аналық бездердің бақыланатын овуляциясы маңызды шарт болып табылады. Аналық бездердің суперовуляторлық реакциясының сандық (овуляция саны, эмбриондардың өнімділігі) және сапалық (эмбриондардың өміршеңдігі) көрсеткіштері гонадотропиндердің дозасына байланысты екені белгілі. Сонымен қатар, қойларда қолданылатын дозалардың нақты белгіленген параметрлері жоқ, өйткені препараттың дозасы түрге, тұқымға, көбею кезеңіне және басқа сыртқы (қоректену) және ішкі (фолликулогенез) факторларға қатысты түзетіледі. Осыған байланысты жергілікті қой тұқымдарының гендік қорын сақтау және оларды ұтымды пайдалану мәселесі өте маңызды. Жергілікті популяциялар мен қой тұқымдарының тұқым қуалайтын белгілері-олардың төмен құнарлылығы, сонымен қатар дала аймағының төтенше жағдайларына жоғары бейімделуі (құрғақ климат, температураның кенеттен өзгеруі) және ауруларға жоғары төзімділік. Аналық бездің гормоналды ынталандыруы мұндай өнімділігі төмен қойларда суперовуляцияны тудыру үшін кеңінен қолданылады. Мақалада отандық ғалымдардың қойлардың суперовуляциясын ынталандыру және қой эмбриондарын трансплантациялау жөніндегі ғылыми еңбектеріне шолу келтірілген. Отандық және шет елдік ғылыми әдебиеттерді талдау суперовуляция туғызу, донорды жасанды ұрықтаныдру, эмбриондарды бөліп алу және сапасын бағалап, тасымалдау сияқты биотехнологияның заманауи жетістіктерін қолданудың нақты қой шаруашылығындағы өсімді иолайтуғы қосатын үлесін дәлелдеуге мүмкіндік берді.

The rate profiles obtained for solutions containing 10-50% DMSO by volume exhibited clear maxima that shifted to higher concentrations of DEHIES as a function of DMSO added. For solutions containing 60-80% DMSO, there was no maximum in the rate profile, and inhibition of the reaction took place. Solutions containing 90% by volume of DMSO exhibited much higher reaction rates and considerably more catalysis. The experimental results are explained in terms of the Hughes-Ingold Theory, specific solvent effects, polarity, and internal pressure of the reaction medium. The interpretation and discussion of the results takes into consideration the formation of the stoichiometric hydrate DMSO.2H2O and the inhibitory effect of dimethyl sulfoxide on the formation of micelles of DEHIES.

Authors: Valdug Claudete J. , Valduga Eunice , Adaime Martha , Viaro Nadia
Published: June 2021

The Pt indicator electrode has been commonly used for redox potentiometric titrations. In this work the Nb indicator electrode is suggested as an alternative for the Pt indicator electrode for the redox potentiometric titrations of the system Fe(ll)/K2Cr2O7. The utilization of the proposed electrode has been studied with and without passivation. The passivation is made by electrode immersion in oxidising anodic inhibitor of NH4MoO4. The result was an observed increase of the potentiometric leap from 30 mV to 60 mV, allowing better visualization of the equivalence point. The same equivalence point was observed with the conventional and proposed electrode. With the Nb electrode, an inverse potentiometric leap was also obtained.

Published: June 2021

During the operation of electric induction motors used to drive passenger elevators, electro-mechanical transient processes occur, which can cause unacceptable dynamic loads and vibrations. In this regard, research is needed both at the design stage and for operating elevator systems to determine the arising impact currents and torques, in order to propose solutions for their limitation within pre-set limits. Paper deals with starting processes in a two-speed induction motor drive of a passenger elevator. The equations for the voltages of the induction motor are presented in relative units in a coordinate system rotating at a synchronous speed. The values have been obtained for the torques, the rotational frequencies and the currents when starting at a high speed and passing from high to low speed.

Published: June 2021

Physical, mental, and emotional changes in the elderly need family care, since family assistance alleviates aging difficulties. They need the assistance of individuals close to them to be able to enjoy life in old age and be happy or feel pleased. Older reliance is created by the fact that many elderly individuals are suffering from physical, cognitive, and psychological decline, which means that the elderly are going through changes that are unfavorable. As a consequence, physical mobility issues will impede the elderly's ability to carry out everyday tasks independently. Family serves as a secure and serene haven for relaxation and healing, as well as a tool for mastering emotions such as empathy, care, and concern for the elderly.
A RETERRITORIALIZAÇÃO PESQUEIRA NO ESTADO DO PARÁ: REPRODUÇÃO CONTRADITÓRIA DAS RELAÇÕES CAPITALISTAS
Authors: Sombra Daniel , Mota Giovane Da Silva , Leite Alegria Dos Santos , Castro Carlos Jorge Nogueira de
Published: June 2021

O ordenamento territorial pós-1960 na Amazônia erige uma nova organização espacial, com as empresas capitalistas como agentes hegemônicos, com destaque para a indústria pesqueira no Nordeste Paraense. A apropriação do território pelos novos agentes hegemônicos desterritorializou os agentes que realizavam uma apropriação comum do território: os pescadores artesanais. Essa desterritorialização implicou numa reterritorialização (modo de reprodução da pesca artesanal encontrado a partir da inserção da pesca industrial: uma territorialização precária) que se deu através: a) da especialização em pescar espécies que não interessam aos grandes atores; ou b) da conversão em força de trabalho para os novos agentes sociais. A natureza a ser (re)territorializada é, porém, tecnificada, no sentido em que já não pode ser apropriada ou concebida conforme a técnica e as práticas anteriores. Daí deriva a hipótese central de que a produção da nova organização espacial da pesca no Nordeste Paraense se dá simultaneamente com a territorialização “enquanto recurso” para alguns e reterritorialização “enquanto abrigo” para outros. Sob estes moldes, a reterritorialização da pesca artesanal é um momento da reprodução ampliada do capital, sob a forma de acumulação primitiva (acumulação por espoliação).

Published: June 2021

Este trabalho tem como objetivo quantificar e espacializar queimadas obtidas a partir dos produtos MYD14 e MOD14 estimadas pelo sensor MODIS que ocorrem em todo o Cerrado. Os dados de queimadas foram comparados com os dados do produto do índice de vegetação denominado MOD13A3 NDVI (para pontos sorteados), também estimados pelo sensor MODIS a fim de compreender as interferências das queimadas na resposta biofísica da vegetação e suas mudanças em uma série temporal de 14 anos (2000 – 2014) a partir da Transformada Wavelet. A análise da distribuição espacial dos focos de queimadas indica que os locais mais atingidas pelas queimadas ocorrem em áreas de savana na porção norte do bioma. A utilização da Tranformada Wavelet para analisar variações nos sinais de NDVI se mostrou eficiente para verificar os cenários passados e atuais da vegetação, além de auxiliar na análise do comportamento fenológico da vegetação.

Published: June 2021

Este trabalho aplicou o modelo Soil and Water Assessment Tool (SWAT) para analisar a influência das mudanças do uso do solo no escoamento superficial e na produção de sedimentos, em uma bacia hidrográfica do bioma caatinga no Nordeste do Brasil. Este estudo consistiu em: (a) mapeamento do uso do solo para 1984 e 2015, (b) calibração do escoamento superficial; e (c) simulação do escoamento superficial e produção de sedimentos a partir do cenário de uso do solo no ano de 2015. O modelo SWAT foi calibrado usando dados diários de precipitação e escoamento superficial de 1977 a 1978. Os dados de precipitação também foram utilizados na simulação dos processos hidrossedimentológicos para o cenário de 2015. Os resultados indicam um bom ajuste na calibração, com valor de Nash-Sutcliffe = 0,85 e R² = 0,89. Para o escoamento superficial, o valor médio observado foi de 0,360 m³/s (com uso do solo de 1984), e 0,854 m³/s (com uso do solo de 2015). Para a produção de sedimentos, o valor estimado para 1984 (período de calibração) foi de 0,34 ton/ha.ano, enquanto para 2015 foi de 1,34 ton/ha.ano. Esses resultados mostram que mudanças futuras podem ter um significante impacto no escoamento superficial e na produção de sedimentos.
