Ficção como antropologia especulativa: embates comunicativos na literatura de Juan José Saer
Authors: Manna Nuno , Jácome Phellipy
Published: May 2021

Este ensaio busca explorar os embates comunicativos que emergem na leitura do romance “O Enteado”, de Juan José Saer, tomando a ficção literária como possibilidade de reflexão sobre a cultura e da experiência de conflitos entre identidade e alteridade. Propondo uma compreensão da ficção como uma forma de antropologia especulativa, exploramos, pela obra do escritor, questões relativas à comparação entre diferentes perspectivas: o que acontece se essas comparações se dessem no interior do espaço-tempo ficcional desdobrado por uma obra particular? Quais imbricamentos e problemáticas são trazidas pela ficção como exercício de distanciamento e de reflexão sobre as nossas formas de vida? Como ficções particulares avançam e questionam os limites dos nossos mundos possíveis? O livro de Saer nos é particularmente instigante na busca destes interrogantes, na medida em que parte de um relato presumidamente histórico para recontá-lo através de um narrador-personagem que parece não encontrar seu lugar em nenhum dos dois mundos por ele frequentado –o dos europeus e o dos Colastiné- o que gera reflexões inquietantes sobre ambos.
Os artifícios da voz: Francisco de Paula Brito e a Sociedade Petalógica
Authors: Martins Bruno Guimarães
Published: May 2021

Evitando a dicotomia entre oralidade e escrita, perseguimos na historiografia da imprensa e da literatura por indícios da “voz” ou da “palavra”, assim como sugerido por Paul Zumthor e Michel de Certeau. Para tanto investigamos como o editor pioneiro Francisco de Paula Brito (1809-1861) que desejamos caracterizar como editor a voz, transfigurando-a da polifonia cotidiana para os impressos oitocentistas, especialmente ao publicar os relatos das famosas sessões da “Sociedade Petalógica” entre 1853 e 1858. Com o artifício das petas (mentiras), os membros desta divertida sociedade visavam “contrariar os mentirosos, mentindo-lhes”, o que verdadeiramente tratava-se de uma ação política indireta. Ao analisar este exemplo sociabilidade literária, pretendemos demonstrar que as condições de edição e performance do texto são relevantes para traçar relações entre literatura e realidade cotidiana, especialmente se pensarmos nas condições pouco propícias para a disseminação do texto literário em meados do século XIX.

Mitologias: falsa consciência e consciência partida
Authors: Motta Leda Tenório da
Published: May 2021

Pesam-se aqui as referências marxistas do primeiro Roland Barthes, de modo a ressaltar as diferenças metodológicas de uma nova crítica cultural, informada pela leitura de Saussure. Isso demanda distinguir entre “mistificação” e “mitificação”, assinalando-se a maneira, em seu momento inédita e surpreendente, como Mitologias passa a formular uma semiologia da conotação e a sediar a alienação burguesa na execução da linguagem. A esta outra forma de consciência propomos chamar “consciência partida” ou “consciência infeliz”, todos termos de Barthes, por contraposição à “falsa consciência”, tal como entendida no quadro das premissas teóricas marxistas para o fetiche da mercadoria.
Estilística, uma possível metodologia para a análise de narrativas televisivas
Authors: Hergesel João Paulo , Ferraraz Rogério
Published: May 2021

A Estilística, considerada capaz de compreender os aspectos afetivos da expressão, teve sua origem nos estudos aristotélicos de Retórica e Poética. Embora consolidada pela Linguística e pela Literatura, pesquisadores de Comunicação vem encontrando na Estilística a resposta para muitas de suas indagações. Já apropriada pelos estudos de Cinema, a Estilística caminha para encontrar nos estudos televisivos uma abertura pela qual pode oferecer auxílio nas análises descritivas e na interpretação contextual dos produtos. Este artigo, que oferece um resgate histórico dessa disciplina cunhada por Charles Bally e Leo Spitzer, apresenta-a como uma possível metodologia para análise de narrativas televisivas, explorando sua contribuição consagrada pelos estudos de obras cinematográficas e da TV norte-americana. Para ilustrar esse raciocínio, faz-se uma reflexão estilística sobre os programas do SBT, segunda maior emissora brasileira.

Este artigo apresenta a “Metodologia de análise do modo parceiro de fazer telejornalismo”, criada para observar as reportagens produzidas para o quadro Parceiros do RJ/TV Globo. A iniciativa resultou na construção de uma narrativa inclusiva que mexe com o padrão Globo de jornalismo. O método tem como matriz teórica três obras: O que falar quer dizer: a economia das trocas simbólicas (BOURDIEU, 1998), O discurso do jornal (REBELLO, 2000), e Análise do programa de televisão (MACHADO, 2012).
mesmo e o outro em Blade Runner
Authors: Soares Rosana de Lima , Anaz Silvio
Published: May 2021

Este artigo tem como objetivo apresentar possibilidades teóricas e metodológicas para o estudo de narrativas audiovisuais contemporâneas presentes nas mídias. Por meio da análise mitocrítica e de aportes conceituais advindos da teoria geral do imaginário (Gilbert Durand), analisaremos alguns aspectos míticos presentes no filme Blade Runner, o caçador de androides (Ridley Scott, 1982) apontando para processos de identidade e de alteridade nas mídias, e articulando questões relativas à construção de estigmas e estereótipos nelas presentes. Nesse percurso, destacaremos os processos de humanização do protagonista e do antagonista em Blade Runner, o que nos leva à questão da empatia e da aceitação do Outro e do diferente nas narrativas audiovisuais contemporâneas.
Das linguagens midiáticas à hipótese rock-education
Authors: Fantin Monica , Alves dos Santos José Douglas
Published: May 2021

O texto reflete sobre as linguagens midiáticas e os processos educativos no contexto da cultura digital mediados pela singularidade da música. Na confluência das linguagens midiáticas, destacamos o trabalho com multiletramentos e a perspectiva da mídia-educação, que inspira nossa hipótese rock-education entendida como uma atitude pedagógica e expressão cultural para um agir crítico e criativo diante do conhecimento, da cultura e dos processos de ensinar e aprender. A hipótese dialoga também com a ideia de comunidades pedagógicas e culturais e da escola entendida como espaço de cidadania, fronteiras e intercâmbios. Nas relações entre sujeitos e saberes, o rock-education sugere outras possibilidades educativas na construção de conhecimentos, atitudes e diálogos, para além do gênero musical como “recurso pedagógico” na escola. Pode contribuir também para pensar outras interpretações de mundo, em que práticas educativas tenham na arte e na cultura um denominador comum.

Forecasting Bitcoin Price Based on Blockchain Information Using Long-Short Term Method
Authors: Larasati Kinanti Dhea , Primandari Arum Handini
Published: May 2021

Since its founding in 2008, Bitcoin (financial code: BTC) has emerged as a digital currency in market cap and continues to attract investors and policymakers' attention. In recent years, BTC has high price volatility, a substantial increase in 2016, followed by a significant decline in 2018. Unlike stock markets, BTC  is open for 24x7 dan has no closing period. It means everyone can trade it for any time. However, this flexibility carries investment risk. This research attempts to forecast BTC's price by considering the blockchain's information to minimize the risk. We employ Long-Short Term Memory (LSTM), the artificial Recurrent Neural Network (RNN) architecture. Its model can avoid long-term problems. The data  used is BTC's price and blockchain information data from August 4, 2018, to January 21, 2020. The model with 20 neurons and 500 epochs has the smallest MSE value. Then a prediction has an accuracy rate of 91.07%.

Authors: Al-Qudah Safa'a , Abuhussein Leyla , Sbaihi Samar Al
Published: May 2021

Background: Vitamin D Deficiency in children is a worldwide health
problem. Yet, there is little known about awareness of parents regarding
this issue in Jordan. The recent study aimed to assess the mothers’
knowledge and practices toward vitamin D deficiency in infants and up to
age of 6 years. Methods: an online questionnaire was distributed as
Google Form on mothers of children between 0-6 yeas, assessing their
knowledge about vitamin D, its deficiency, and their practices toward
vitamin D deficiency for their children, Descriptive statistics and
Chi-Square test were performed. Results: Most of mothers (64.8%) were
aged between 30-40 years, and had education level of Bachelor’s degree
(63.3%). Sunlight was considered the main source of vitamin D (89.1%),
while fish and eggs were the main dietary sources (63.5%, 65.5%,
respectively). Vitamin D was considered important for bone and teeth
health (93.9%). The majority of participants reported lack of sun
exposure and decreased vitamin D rich foods as risk factors and rickets
as complication of vitamin D deficiency (98.5%, 96.4%, 89.3%,
respectively). Most of mothers (65.1%) indicated the time before 10 AM
as the best time of day to expose baby/child to the sun. The majority of
participants (82.2%) believe that vitamin D deficiency is a common
health problem in children in our country, and 86.4% think they need
more information on vitamin D deficiency in children. Age, nationality,
nature of housing, and age group of children had an impact on
knowledge’s level of participants. Conclusion: Most of participants were
aware of vitamin D sources, benefits, risk factors and complications of
deficiency, although there was inadequate knowledge among respondents
was found in certain domains of vitamin D. More education is required
for mothers about vitamin D and its deficiency.

A single-center validation of the effectiveness of photoplethysmography-based smart device for screening obstructive sleep apnea
Authors: Yibing Chen , Wang Weifang , Zhang Hui , Guo Yutao , Xie Lixin , Chen Yun-dai
Published: May 2021

Background: Obstructive sleep apnea (OSA), the most common upper-airway
disease, is closely associated with cardiovascular risk. However, the
early screening of OSA is challenging, relying on polysomnography (PSG)
or home sleep apnea test (HSAT) in hospitals. Photoplethysmography (PPG)
has been developed as a novel technology for OSA screening, but the
validation of PPG-based smart devices is limited as compared to that for
PSG or HSAT. Objective: This study aimed to investigate the feasibility
and validity of PPG-based smart devices in the screening of OSA.
Methods: A total of 119 consecutive outpatients were recruited from the
Chinese PLA General Hospital and assessed for a whole-night sleep using
a smartwatch, PSG, or HSAT. Results: 17/119 patients were excluded from
the study due to the poor quality of PPG signals. Among the remaining,
83 patients were diagnosed with OSA. Compared to HSAT devices, the
accuracy, sensitivity, and specificity of PPG-based smart devices in
predicting moderate-to-severe OSA patients (apnea-hypopnea index,
AHI≥15) were 87.9%, 89.7%, and 86.0%, respectively. Compared to PSG,
the accuracy, sensitivity, and specificity in predicting sleep apnea in
patients (AHI≥5) were 81.1%, 76.5%, and 100%, respectively. Moreover,
for moderate-to-severe OSA patients (AHI≥15), the predictive ability of
PPG-based smart devices in OSA did no differ significantly as compared
to HSAT (P=0.75) or PSG (P=0.52). Conclusions: The PPG-based smart
devices performed adequately in detecting OSA; nevertheless, validation
in a large-scale population is imperative.

Pathogens may elicit a high selective pressure on hosts and can alter
genetic diversity over short evolutionary timescales. Intraspecific
variation in immune response can be observed as variable survivability
from specific infections. The great gerbil (Rhombomys opimus) is
a rodent plague host with a heterogenic but highly resistant phenotype.
Here, we investigate if the most plague-resistant phenotypes are linked
to genomic differences between survivors and susceptible individuals by
exposure of wild-caught great gerbils from Northwest China to plague
(Yersinia pestis). Whole genome sequencing of ten survivors and
ten moribund individuals revealed a low genome-wide mean divergence,
except for a subset of genomic regions that showed elevated
differentiation. Gene ontology (GO) analysis of candidate genes within
regions of increased differentiation, demonstrated enrichment of
pathways involved in transcription and translation and their
regulation), as well as genes directly involved in immune functions,
cellular metabolism and the regulation of apoptosis. Differential RNA
expression analysis revealed that the early activated great gerbil
immune response to plague consisted of classical components of the
innate immune system. Our approach combining challenge experiments with
transcriptomics and population level sequencing, provides new insight
into the genetic background of plague-resistance and confirms its
complex nature, most likely involving multiple genes and pathways of
both the immune system and regulation of basic cellular functions.
Nano-encapsulation of sweet basil essential oil based on native gums and its application in controlling the oxidative stability of Kilka fish oil
Authors: Aboutalebzadeh Sahar , kenari reza esmaeilzadeh , Jafarpour Ali
Published: May 2021

In the first section of this study, the effects of two different
extraction methods on the efficiency and chemical composition and
antioxidant activity were compared. Extraction efficiency of
supercritical fluid was significantly higher than distillation of water.
The results showed that antioxidant activity increased by increasing the
concentration of the essential oil. In the second part of the study, to
evaluate the impact of various walls, Lepidium sativum (LS) , Lepidium
perfoliatum (LP) and a combination of both (LP/LS)were used for
nano-encapsulation essential oil of basil by freeze-drying.
Nanoencapsulate powder was evaluated regarding efficiency, particle
size, PDI, Zeta poteintial,SEM, viscosity, Brix,pH, density.humidity, aw
and FTIR. In the third part, essential oil of basil in free mode at
Level 1%, 5% and 20% and in encapsulated at the level of 2% and TBHQ
at 0.01% added to Kilka oil without antioxidants and then the samples
were place in an oven at 60 ° C for 16 days. Storage stability of kilka
oil regarding peroxide, thiobarbituric and color were analyzed. The
results showed that basil essential oil had antioxidant activity and
reduced the oxidation process, and also nanocapsule essential oil
(especially with a coating of LP gum) showed better antioxidant activity
than free essential oil, so that its antioxidant activity is competitive
with TBHQ synthetic antioxidants. Finally, we can conclude that it is
possible to substitute synthetic antioxidants by natural ones like olive
leaf phenolic compounds but we have to apply some forms of encapsulation
techniques in order to protect their properties.
Optimization of megakaryocyte trapping for platelet formation in microchannels
Authors: Baydar-Atak Gunay , Insel Mert , Oruc Muhammed , Sadikoglu Hasan
Published: May 2021

Platelets (PLTs) are responsible for stopping bleeding. They are small cell fragments produced from megakaryocytes (MKs) in the bone marrow. Low platelet count is a significant health problem for a patient. PLTs can usually be stored for up to 5 days prior to transfusion. Instantaneous production of PLTs from isolated and stored MKs is crucial for the patient?s health. Thanks to microfluidic platforms, PLTs can be produced instantaneously from MKs. Herein, we have computationally studied fluid dynamics in the microchannels with slit structures and different inlet geometries. Analysis of the flow dynamics was performed by the commercial analysis software. The effects of flow rates and the angle between the inlet channels on the MKs trapping were investigated. The optimization of the angle between inlet channels and flow rates of main and pressure flows was done with response surface methodology (RSM) by counting the trapped MKs. The optimum conditions lead to the percentage of trapped MKs being 100 with a relative deviation of <1%. We also concluded that flow rates to trapping a higher amount of MKs are as important as the angle between the inlet channels.

Authors: Faramarzi Zohreh , Abbasitabar Fatemeh , Jahromi Jalali , Noei Maziar
Published: May 2021

Recently, development of the QSPR models for mixtures has received much attention. The QSPR modelling of mixtures requires the use of the appropriate mixture descriptors. In this study, 12 mathematical equations were considered to compute mixture descriptors from the individual components for the prediction of normal boiling points of 78 ternary azeotropic mixtures. Multiple linear regression (MLR) was employed to build all QSPR models. Memorized_ ACO algorithm was employed for subset variable selection. An ensemble model was also constructed using averaging strategy to improve the predictability of the final QSAR model. The models have been validated by a test set comprised of 24 ternary azeotropes and by different statistical tests. The resulted ensemble QSPR model had R2 training, R2 test and q2 of 0.97, 0.95, and 0.96, respectively. The mean absolute error (MAE), as a good indicator of model performance, were found to be 3.06 and 3.52 for training and testing sets, respectively.

Published: May 2021

The pathogenesis of type 2 diabetes mellitus (T2D)
might change with increasing age. Here, we used a stratification based on age
of diagnosis, to gain insight in the genetics and causal risk factors of T2D
across different age groups. We performed genome-wide association studies
(GWAS) on T2D and T2D subgroups based on age of diagnosis (<50 years, 50-60,
60-70, and >70 years; total of 24,986 cases). As controls, we used participants
who were at least 70 years of age at the end of follow-up without developing T2D
(N = 187,130). GWAS identified 208 independent
lead SNPs mapping to 69 loci associated with T2D (p<1.0e-8). Among others, SNPs mapped to CDKN2B-AS1 and multiple independent SNPs mapped to TCF7L2 were more strongly associated to cases
diagnosed after age 70 years than to cases diagnosed before age 50 years. Based on the different case groups, we performed two-sample Mendelian
Randomization. Most notably, we observed that of the
investigated risk factors the association between body mass index and T2D attenuated
with increasing age of diagnosis. Collectively, stratification of T2D based
on age of diagnosis reveals subgroup-specific genetics and causal determinants,
supporting the hypothesis that the pathogenesis of T2D changes with increasing
age.

Published: May 2021

Non-fluent variant primary progressive aphasia (nfvPPA), a subtype of frontotemporal lobar dementia syndrome, has been proven to have various pathological diagnoses. A 63-year-old woman and 71-year-old man separately visited our clinic for language dysfunction. Both patients showed non-fluent speech. The female patient showed personality change accompanied by language dysfunction, while the male patient had parkinsonian symptoms such as bradykinesia and cogwheel rigidity. Both patients were clinically diagnosed with nfvPPA. Several years after the first visit, the patients died, and a brain autopsy was performed. On postmortem examination, the female patient was pathologically diagnosed with Pick’s disease, while the male patient was diagnosed with progressive supranuclear palsy. Our report suggests that nfvPPA patients might show distinct clinical features depending on underlying pathologies.
Matter in 2+1 Dimensions at Finite Density with Chern Simons Interactions
Authors:   , Stratiev Stanislav
Published: May 2021

We study several matter Chern-Simons models at finite chemical potential. In the SU(N) theory we discover a colour-flavour locked Bose condensed ground state with vacuum expectation values for both the scalar and gauge fields. We identify this ground state with the non-commutative Chern-Simons description of the quan-tum Hall eect. We compute the quadratic spectrum and discover roton excitations. We find a self-consistent circularly symmetric ansatz for topological non-abelian vortices. We examine vortices in abelian Chern-Simons theory coupled to a relativistic scalar field with a chemical potential for particle number or U(1) charge. The Gauss constraint requires chemical potential for the local symme-try to be accompanied by a constant background charge density/ma-gnetic field. Focusing attention on power law scalar potentials |Φ|2s, s ∈ Z, which do not support vortex configurations in vacuum but do so at finite chemical potential, we numerically study classical vortex solutions for a large winding number |n|  1.

Published: May 2021

Riverbank erosion, a regular natural phenomenon in the lower confluence deltaic country like Bangladesh. Among the natural disaster effecting Bangladesh each year, river bank erosion is the most vulnerable in term of effected people and loss of assets. As a riverine country there are huge number of rivers and their tributaries and distributaries criss-crossed over the country, but the mighty three rivers like the Padma, Jamuna and Meghna are mostly known for the erosional characteristics. River bank erosion possesses as a significant, endemic and recurrent natural disaster in Bangladesh by these rivers. This research is designed to explore the erosional pattern of the river Jamuna and its impact on population migration and the adaptation strategy of the migrants. For the study primary data were collected from the study area through questionnaire survey, FGD and mapping analysis while secondary data were collected from published and unpublished reports of different offices such as land office, union parisad office, census report, BBS, WDB etc. However, to analyze the trend of erosion mapping analysis was conducted through ArcGIS 10.3 and for statistical analysis SPSS software was used. The research findings indicate that the Jamuna is a highly dynamic river in term of erosion. Due to its severity and dynamic erosional pattern possess mass number of people to be displaced by losing settlements and agricultural land. River bank erosion of Jamuna River invites many obligatory problems at different stages of displacements like loss of residence, household assets, agricultural land etc. Though it pushes the victims to readjust all their activities associated to livelihood pattern as an adaptation strategy with a newer socio-environmental situation, but very often becomes unable to recover the damage even spending considerable time. From this point of view, river bank erosion needs to be considered as a unique disaster and give attention to take comprehensive riverbank erosion management policy, so that problem can be minimized to a tiny scale.

The article explores different points of view regarding the dialectics of the socio-political and historical development of global constitutionalism and its relationship with changes in the socio-political and state-legal system on a planetary scale (as a historically integral part in the development of society at any stage of the historical era, opposite to autarkic tendencies; as a phenomenon inherent in modern society). In this regard, the paper concludes that the socio-political and historical transformations of global constitutionalism as a social concept in the near future will largely determine the main directions of the socio-political and state-legal development of nation-states. The purpose of the research: from the standpoint of the socio-philosophical methods of cognition of social reality and the ideas reflecting it, to analyze the socio-political and historical transformations of global constitutionalism in the modern world. Object of research: the phenomenon of globalization of socio-political, state-legal and financial-economic development of national societies and states as a phenomenon of social reality, highlighted in the social concept of global constitutionalism.

The purpose of the research: from the position of socio-philosophical methods of cognition of social reality and ideas reflecting it, to analyze the dialectic model in the doctrine of social changes in the philosophy of global constitutionalism. An analysis of the dialectical method as a theory for understanding social change in the philosophical concept of global constitutionalism has shown that:  in the process of its formation, the Hegelian concept of dialectical development and the dialectical materialism of the Marxist-Leninist type, including its basic laws; it is aimed at developing a system of arguments to justify the natural evolutionary nature of the origin of the world capitalist system; the process of removing the qualitatively heterogeneous opposites accumulated in the process of social development is also subordinate to the general logic of the development of the world capitalist system.

Two Suns? Data, Algorithms, Spaces and Techno Feudalism
Authors: Cleave Peter
Published: May 2021

A main thread in the Two Suns? series might be summed up as follows. There are several spaces or forms of space involved; territorial space, outer space, cyberspace and living space, And there is data to be found and owned in each of these spaces. That data may be processed using algorithms in each space and across all spaces. With such a thread in mind one argument in the Two Suns? series so far and going forward is as Data, Algorithms, Spaces, and Techno Feudalism follows; we should treat Big Tech as an incipient state with its own entry and exit points and its own infrastructure rather than constantly framing discussion in terms of a nation-state like the USA.  The latter may have been and may still be a host for the Algorithmic State but this is not necessarily ongoing.  Furthermore there is a range of nation states from the strong to the barely formed ranging through, say the examples of the USA, Australia and Myanmar and a varying use and influence of the algorithm within these nation states.

Earlier the idea that we might be looking at techno feudalism was advanced and Bleuca makes a comparable point above. Are the spaces outlined here the bondage context for the new feudalism, the new political economy which is a version of the political economy found in feudalism? Or are we looking at a new animal, something we are not sure how to describe?
Integration of Library Data on Reference Books: with Service Oriented Architecture Implementation methods and (ESB) Enterprise Service Bus
Authors: Christianto Erwien
Published: May 2021

Libraries have an important role in mastering science and technology as well as a center for information activities. Currently, the library extends its services not only in hardcopy but also in softcopy and provides faster information retrieval capabilities. Service Oriented Architecture (SOA) provides better multi-platform integration through network infrastructure. This job is to implement SOA in a Library Information System based on Glassfish Enterprice Service Bus and MySQL database. The methods for implementing library application design using SOA and ESB are built using a business process approach with several stages (M. Weske, 2006). The application of the methodology to be implemented with SOA and ESB is built using a business process approach with the following stages: The first stage, map design for integration of library requirements, the second stage is service interface design, the third stage builds relationships between services combine services that have been previously created by interaction with other services. The fourth stage is determining the logic flow that will evaluate the service logic flow that has been created with existing business processes. The fifth stage builds scenarios for shared perceptions and refining existing processes. The results show that the design has faster search capabilities that match the needs of the library.

Indonesia is one of the largest culinary attractions in Southeast Asia. The culinary diversity in Indonesia encourages stakeholders to create restaurant businesses with effective and efficient business processes. One of the efforts to make the restaurant business process effective and efficient is to build a restaurant management information system. By using a system, business actors will be able to control and evaluate their business with appropriate reports. For this reason, the purpose of this study is to build a restaurant management information system using the RAD (Rapid Application Development) method, because building this application requires a systematic, structured, and object-oriented process. The RAD method emphasizes a high quality systems, fast development and delivery and low costs development process [1] so that this process requires a serious role from business actors to build a restaurant management information system.   The results of this system design can make it easier for business actors to control the business process from the customer to the kitchen so that the food and beverage ordering process will be served quickly. The GUI restaurant management information system is made interactively so that customers and business actors can easily understand the system. The test results of this system use black-box testing, with the conclusion that the system is successful to run.

From the use of the internet, it can also be used by sales that have Android mobile-based bread ordering information systems. By only using a cell phone, system users can order bread. This can be a tool in the special community in ordering bread. As with computers, mobile phones can also install a variety of software or software that they want. Besides, android phones can also be used for transactions. Like making a bread order transactions through an android phone. The stages that will be carried out by the author for the application development process include analysis and needs, application design, and application interface design, so that the application is made easy to use. The ordering system designed can make it easier for admin to view order details, check stock, manage customer data by using a database as a storage medium, and can also provide customers to buy stock of bakery goods available at these outlets to provide accurate information. The SMART method has been proven to be implemented in searches based on user preferences, and gives different results if the value of the criteria entered is different. However, conventional search methods are still provided in addition to searching for goods using the SMART Method.

Praktek budidya tanaman telah banyak dilaporkan dapat mempengaruhi sifat tanah maupun keragaman organisme di dalamnya. Penelitian ini bertujuan untuk mengetahui dampak pola budidaya tanaman cengkeh terhadap sifat kimia dan populasi cacing tanah. Penelitian ini dilakukan pada bulan November 2019 - Februari 2020 terdiri dari 2 tahapan, yaitu pengamatan total populasi cacing tanah dan analisis sifat kimia tanah. Pengamatan total populasi cacing tanah dilakukan dengan membuat lubang sekitar 50 cm x 50 cm pada kedalaman 30 cm pada kebun cengkeh yang ditanam secara monokultur dan polikultur kemudian cacing tanah dimasukkan ke dalam botol yang telah berisi alkohol dan diberi label. Pengambilan sampel tanah menggunakan metode purposive sampling untuk analisis sifat kimia tanah. Parameter yang diamati adalah pH (H2O, KCl); C-organik (metode Walkley dan Black); N-total tanah (metode Kjeldahl); P2O5-tersedia (metode Olsen); kation basa Ca2+, Mg2+, K+, Na+ dan KTK (metode N NH4OAc pH 7.0); kation asam H+ dan Al3+ (metode N KCl), dan populasi cacing tanah. Hasil penghitungan populasi cacing tanah pada lokasi budidaya cengkeh polikultur dan monokultur masing-masing sebanyak 14,4 ekor dan 7,75 ekor. Sifat kimia tanah seperti pH (H2O, KCL), C-Organik, nisbah CN, P2O5-tersedia, kation basa Ca2+, Mg2+, K+, Na+, kapasitas tukar kation (KTK) dan kejenuhan basa (KB) pada pola budidaya polikultur cenderung lebih tinggi dibandingkan dengan monokultur. Kation asam Al3+ pada pola budidaya secara polikultur dan monokultur <0,05 ppm dan kation asam H+ pada pola polikultur lebih rendah dibandingkan monokultur. Pola budidaya tanaman cengkeh secara polikultur menciptakan kondisi sifat kimia dan populasi cacing tanah lebih baik dibandingkan monokultur dan dapat dijadikan sebagai rekomendasi bagi petani dalam budidaya cengkeh.

Authors: Mooney Angela Rodriguez
Published: May 2021

Este artigo investiga a reescritura da corporeidade da mulher negra no romance Becos da memória, de Conceição Evaristo, publicado em 2006. Intenciona-se analisar a forma como o corpo e seus símbolos são representados no romance e como essas construções desestabilizam juízos morais e estereótipos que ancoram o corpo da mulher negra a um passado escravizado, criando novas territorialidades onde a subjetividade da mulher negra é visibilizada e valorizada.
