Authors: Xavier Diego De Arruda , Dos Reis Caio Daniel Nascimento , Da Silva José Francisco Berrêdo Reis
Published: February 2022

O objetivo deste estudo é analisar o estuário do rio Sucuriju quanto às distribuições dos parâmetros sedimentológicos, geoquímicos e físico-químicos intersticiais, a fim de auxiliar estudos sobre vulnerabilidade a risco ambiental, quanto a um possível impacto decorrente de derrame de óleo na região do Cabo Norte, no estado do Amapá. Foram coletadas 66 amostras de sedimentos superficiais, submetidas a análises das porcentagens granulométricas, de teores de carbono orgânico, nitrogênio total, fósforo total, salinidade intersticial, pH intersticial e potencial redox intersticial. As porcentagens granulométricas apresentaram médias para areia de 19,51 ± 13,44%, para silte de 72,50 ± 11,17% e para argila de 7,98 ± 4,49%. Salinidade, pH e potencial redox registraram médias de 20,76 ± 2,59, 7,20 ± 0,26 e 192,32 ± 129,96 mV, respectivamente. Os resultados de carbono orgânico, nitrogênio total, fósforo total e a razão C/N apresentaram, respectivamente, médias de 1,34 ± 0,71 g.kg-1, 0,38 ± 0,23 g.kg-1, 103,93 ± 63,89 g.kg-1 e 4,45 ± 3,96. As características sedimentares e geoquímicas apresentadas para o estuário do rio Sucuriju, somadas aos processos hidrodinâmicos e climáticos da região, determinaram os possíveis pontos de maior vulnerabilidade do sistema estuarino em relação a incidente com óleo. Estes pontos estão localizados nas áreas marginais e em áreas adjacentes à foz do sistema estuarino. Esse resultado servirá de base para a compreensão e a elaboração de possíveis planos de mitigação a eventos dessa magnitude.

Shifting cultivation systems (SCS) are currently restricted to tropical areas. The classical nutrient flow model for SCS considers increasing soil fertility from the conversion phase, with the addition of nutrients contained in the biomass that was slashed and burned, and made available through ash. This study assessed the impacts of the conversion and cultivation phases on soils subjected to an SCS practiced quilombola populations of the Atlantic Forest, Brazil. We used a diachronic method in six experimental plots divided into two fallow age classes (10-15 and 25-30 years). The results showed that fire does not have a primary role in the cycling and maintenance of the stock of nutrients in the soil/vegetation complex. Furthermore, the soil fertility status was not significantly altered during the conversion and cultivation phases. Thus, the quilombola SCS shows specificity and that soil fertilization does not necessarily occur during the conversion and cultivation phases of SCS. The soils from fallow areas between ten and 30 years have eutrophic fertility conditions in relation to the mature forests, and are therefore viable from an agronomic standpoint. Therefore, the data on the impact of the quilombola SCS on soils concur as proscribed by law.

Published: February 2022

Os estudos petrográficos, geoquímicos e isotópicos realizados em cavernas hospedadas em formações ferríferas bandadas do corpo S11D, Serra Sul, foram fundamentais para entender o processo de formação das cavernas e a sua relação com a gênese do minério de ferro. As rochas coletadas encontram-se em diferentes estágios de alteração intempérica: jaspilito não alterado, jaspilito alterado e minério de ferro, estabelecendo, assim, um perfil de intemperismo. Da base para o topo, foi observada brusca diminuição no teor de SiO2 e aumento relativo no teor de Fe2O3T. As análises isotópicas Pb-Pb apontam valores homogêneos, com assinatura isotópica semelhante às rochas da crosta superior. Os valores obtidos sugerem rochas pouco radiogênicas quando comparadas com as assinaturas isotópicas Pb-Pb dos depósitos de Cu-Au de Carajás. Não foram identificadas mudanças isotópicas que indicassem eventos metamórficos, reativações tectônicas ou percolação de fluidos hidrotermais que perturbassem o geocronômetro Pb-Pb. Tais evidências sugerem que a formação das cavernas e do minério de ferro está relacionada apenas aos processos supergênicos, associados ao desenvolvimento de um perfil de intemperismo.

Objetivou-se analisar a florística e o estoque de carbono (EC) de dois tipos de sistemas agroflorestais (SAF): tradicional, em Cametá, Pará (SAF-CM), e comercial, em Tomé-Açu, Pará (SAF-TA). Utilizaram-se parcelas de 50 m x 50 m, onde foram medidos o diâmetro à altura do peito (DAP) e a altura de todos os indivíduos (ni) com DAP ≥ 5 cm. A biomassa seca dos SAF foi determinada pelo método indireto. Foram inventariados, em média, nos SAF-CM, 2.458 ni ha-1, pertencentes a 12 famílias, 19 gêneros e 19 espécies, enquanto que, nos SAF-TA, 1.249 ni ha-1, pertencentes a nove famílias, 13 gêneros e 13 espécies. Euterpe oleracea (açaí) e Theobroma cacao (cacau) foram as espécies mais importantes nos SAF estudados. O EC foi maior nas árvores do que no açaí e no cacau. O manejo adotado influenciou na riqueza de espécies e no EC. Os SAF-CM mostraram maior resiliência e os SAF-TA, maior antropia. Outras espécies destacaram-se em abundância e EC: Virola surinamensis, Hevea brasiliensis e Carapa guianensis, nos SAF-CM, e Spondias lutea, Bertholletia excelsa e Swietenia macrophylla, nos SAF-TA. Os resultados obtidos põem os SAF como alternativa de produção para consumo, venda e EC, ratificando a viabilidade socioeconômica e ambiental desses agroecossistemas na Amazônia.

O intercâmbio de plantas entre as colônias portuguesas ocorreu ao longo de todo um processo de expansão territorial desde o século XV. O objetivo geral deste artigo foi realizar pesquisa documental em “Poranduba maranhense: relação histórica da província do Maranhão”, a fim de resgatar a história natural das plantas do Maranhão no século XIX, de modo a atualizar as informações de acordo com o conhecimento botânico atual, e, mais especificamente, conhecer as espécies, as procedências e os seus respectivos usos. Foram extraídos 174 etnômios, dos quais 88,51% (n = 154) foram identificados pelo menos em nível de família e 11,49% (n = 20) não tiveram suas identidades botânicas esclarecidas. Destes, 81% (n = 141) são constituídos por espécies nativas e 19% (n = 33), por exóticas. A alimentação humana obteve a maior citação de uso, 31% (n = 58). Os usos madeireiros e medicinais figuraram na sequência, com respectivos 22% (n = 41) e 15% (n = 28). No códice de plantas, constam tanto espécies voltadas para o comércio, como cana-de-açúcar, algodão, tabaco e café, quanto espécies ligadas aos hábitos alimentares do colonizador português, além de grande número de espécies nativas. De maneira geral, a representação de plantas retrata o padrão de colonização.

Published: February 2022

Animais granívoros são frequentemente encontrados entre os mais abundantes em regiões secas. Essa estratégia alimentar parece ser bem-sucedida para Coryphospingus pileatus, por conta da disponibilidade, diversidade e estabilidade de sementes. No entanto, a anatomia craniana desta espécie é pouco conhecida. Assim, descrevemos a osteologia craniana de C. pileatus, uma ave granívora-insetívora da região neotropical, bem como aferir seus dados craniométricos, entender um pouco da relação entre o crânio, a alimentação e a ecologia da espécie e identificar características que podem ser usadas em estudos futuros. Foram utilizados quatro espécimes, dissecados, descritos, mensurados, pesados e desenhados. As estruturas observadas no crânio de C. pileatus apresentam particularidades da espécie e características encontradas em outras da ordem Passeriformes. As principias particularidades anatômicas estão no bico, tais como o bico cônico, robusto e com laterais afiadas, associado ao hábito de descascar sementes, e órbitas, por meio das quais é possível estabelecer uma relação com a ecologia e o comportamento da espécie. Portanto, trabalhos de anatomia e morfologia são importantes no aprofundamento dos conhecimentos, fornecendo mais informações para estudos posteriores e mais abrangentes.

Proteases são enzimas hidrolíticas capazes de degradar proteínas em pequenos peptídeos e aminoácidos, e podem ser isoladas de plantas, animais e microrganismos. A busca por proteases de origem microbiana vem aumentando no mercado mundial devido à sua estabilidade, à alta taxa de produção e ao menor custo que apresenta. O objetivo deste artigo foi investigar a produção de proteases por Lentinus crinitus (L.) Fr. 1825 DPUA 1693, utilizando-se a fermentação submersa. A cultura matriz foi preparada em meio BDA (ágar batata dextrose), adicionando-se extrato de levedura 0,5% (p/v). A fermentação foi conduzida a 30 °C, 150 rpm, por oito dias, utilizando-se meios contendo diferentes fontes de carbono e nitrogênio na síntese de proteases. Na determinação da atividade enzimática, foi adotada azocaseína 1% (p/v) como substrato. Os resultados mostraram que a maior atividade das proteases de L. crinitus foi determinada no meio contendo glicose e gelatina. A atividade ótima dessas enzimas foi determinada em pH 5,0, a 50 °C, e a estabilidade, em pH 5,0, à temperatura de 60 °C. As proteases foram classificadas como metalo, serino e cisteíno proteases. Este artigo sugere o uso potencial de protease de Lentinus crinitus para aplicação na indústria alimentícia, farmacêutica e cosmética.

For parts and assemblies of a turbopump unit (TPU) and a liquid rocket engine, welded joints of steel and heat-resistant alloys are used. Considering that the search for replacements by several materials at once, the study of their mutual compatibility in a product takes considerable time and money. Therefore, it would be better to replace it with one alloy, and the unification of the material used allowed the structure to work as a whole. After exploring various options, the substitutes for research were selected inconel 718.

Published: February 2022

The energy audit has its prime objective which is to evaluate a building’s energy usage hence,   recommend various energy management solutions that can satisfy increasingly demanding requirements of the power systems concerned. In historical building, with high energy consumption trends; decisions must be taken quickly to achieve rapid restoration of reduced energy usages and return of normal energy consumption condition with respect to the occupant behaviour or other energy audit abnormality. This study intends to explore the energy consumption within the month of August 2018 using Energy Software called Energy Lens. These techniques should recognize the existing occupants’ behavioural characteristics in the building from using their appliances and lighting. The use of Energy Auditing software such as Energy Lens helps in assessing a wide range of different building types and environmental performance approach. From the analysis, the total energy consumption from the period of 1st august 2018 to 31st august 2018 was determined from the Energy Lens software to be 13,545kWh energy consumed. Heat loss of building (Qloss) was calculated as 12.905W, the Building design heat loss (H) was calculated as 3.226W/K and Total ventilation heat loss (Qvent) was calculated as 13,994.7W.

Published: February 2022

La presente investigación tiene como objetivo principal estimar el impacto de los cambios en los patrones de precipitación sobre la estructura y funcionalidad del ecosistema de pastizal. El lugar donde se llevó a cabo la investigación fue la comunidad de Consac, distrito de Canchayllo, provincia de Jauja. Se simuló tres niveles de disminución de precipitación, para lo cual se construyeron los “rainout shelters”; interceptores de lluvia que constituyeron los tratamientos a 3 niveles de intercepción de lluvia: 0, 30 y 70%. Con estos equipos, se evaluó la respuesta de la estructura florística del área y de los grupos funcionales a la reducción de las lluvias durante el periodo de octubre de 2015 a junio del 2016, además de la variación del vigor y la productividad de una especie.

Los resultados encontrados muestran que la reducción de los patrones de precipitación analizados tuvo un impacto significativo en la relación porcentual de las gramíneas, graminoides y herbáceas. Se observó que el porcentaje de herbáceas disminuyó hasta casi un 50% ante un evento de sequía extrema (70% de intercepción) al finalizar el estudio respecto a las condiciones iniciales, mientras que las gramíneas aumentaron proporcionalmente a mayor nivel de intercepción y los graminoides mostraron una menor variación. Del mismo modo, observamos que los niveles de temperatura disminuyeron considerablemente en los dos eventos de sequía simulados, donde se observó temperaturas muy bajas de 6.3°C que tiene un gran impacto en la actividad metabólica de las plantas. Por otro lado, también se encontró que el vigor de las especies claves se vio fuertemente impactada por la reducción de las precipitaciones, lo cual se manifestó también en la productividad de biomasa aérea, que fue mucho menor en las unidades experimentales que tuvieron mayor intercepción de lluvias que en aquellas que recibieron la cantidad normal de precipitaciones.

Estos resultados muestran que el estrés hídrico en los pastizales se manifestó tanto a nivel de grupos funcionales como a nivel de especies, lo cual sugiere que, ante un evento de sequía moderado a extremo, el ecosistema puede alterar rápidamente su estructura original y que probablemente solo aquellas especies que desarrollaron mecanismos de adaptación a las sequías podrán persistir más tiempo como parte de la comunidad vegetal.

Authors: Hsu Chih-Yu , Lin Chiang-Liang
Published: February 2022

Abstract

Achieving net-zero emissions by 2050 is a crucial issue for the global community, and countries worldwide have pledged to support and join this initiative. They have set out ambitious carbon reduction goals to combat global warming. Taiwan should actively participate in reducing carbon emissions and should discuss possible paths and actions required to achieve the 2050 net-zero emissions goal. Solar PV are a crucial technology because replacing fossil fuel energy generation with Solar PV can reduce carbon emissions. Promoting Solar PV can result in reduced carbon emissions, stimulate the development of the Solar PV industry, and establish an industrial supply chain to increase the economic growth and green competitiveness of Taiwan. Therefore, investigating Solar PV and their expected growth can facilitate formulating strategies for Taiwan to achieve net-zero emissions by 2050.

KONSTELASI EKONOMI ISLAM PELUANG DAN TANTANGAN DI ERA GLOBALISASI
Authors: HS Sufyati
Published: February 2022

Islamic economy is an economic system that stand on the principle of justice, where shared
profits and welfare, not personal gain, are the main goal. In the Islamic economic system, the
principles are: first, getting down to the economy is to meet basic needs in order to worship
and to thank Allah SWT; second, setting the real sector in motion to get the currency in
circulation so that no one would be able to accumulate wealth as much as they wish. The
phenomenon of Islamic economic revival in the era of globalization plays a very important role
in dealing with the global economic and financial crisis. The government as a regulator has an
important to achieve the goals of Islamic economy. The goal is falah, which can be achieved
through maslahah optimization. Therefore, with mandate from Allah SWT and the community,
the government’s role in general is to bring what is good for the whole community. There is a
need to observe a number of driving factors behind the Islamic economy revival in the era of
globalization. The first driving factor is the people’s awareness. The ummah plays double roles
as object and subjec of Islamic economy development. Second, human resources, in term of
quantity and quality. Three qualifications of human resources are required to set the Islamic
economy in motion. They are kafa’ah (expertise), himmah (work ethics) and amanah
(trustworthy). Third, self-reliance of the ummah, that is, the need to change the mindset of
Muslims in regard to Islam with sharia values. Fourth, the need for an institutionand support,
complete and conducive system. Fifth, the role and government policy in the development of
Islamic economic system, the support of People’s House of Representatives [DPR] are
immensely important. The government agencies and legislative institution cooperate with
officials in working for the National Sharia Council / DSN-MUI.

Diversity is a fact that is often denied by some who do not want to be responsible, so often assume
others who disagree and not the same as himself as the culprit of mistakes, and he is the most
correct among others. They forget the history of the plurality of the country. This has actually hurt
the already grounded culture in the archipelago that this nation was born into a culture of diversity.
Unfortunately, the person who is reluctant to take responsibility often makes the verses of the Quran
justify his behavior. Consequently, the Qur’an is often politicized for the benefit of the individual, or
even his group by putting aside the cultural heritage mentioned above. Yet the essence of holy
revelation [al-Quran] always tells us to uphold the truth in diversity culture. The culture of
multiculturalism is indeed embodied and legalized in the Qur’an. This is in accordance with the
mission of the Koran itself as a revelation that saalih likulli time wa al-meal that has long confirmed
the legality of difference and diversity.

Islam and Trans-Border Humanity: Humanitarian Intervention in the Perspective of Islam
Authors: Nasution Hilmi Ardani
Published: February 2022

This paper is trying to find the connection between humanitarian intervention and the basic value of Islam. Humanitarian intervention is the current controversial international law phenomena because it is categorized as an action which violated the sovereignty of another state. Humanitarian intervention defined as an intervention performed by a state or a group of states towards another state with the aim to stop or prevent a humanitarian crisis caused by widespread crimes against humanity and gross violations of human rights. There is a strong connection between the basic value of Islam and humanitarian intervention, especially in the context of humanity. Islam is a religion that respects humanity even if it is only a single soul, in the Quran chapter of Al Maidah verse 32 mentioned that whoever kills a soul unfairly it is as though he had killed all mankind.
