Authors: Lokollo Edir , Nelce Mailoa Meigy
Published: June 2020

Hasil perikanan merupakan produk yang mudah mengalami kebusukan, sehingga diperlukan teknik penanganan yang cermat dan tepat untuk mempertahankan mutunya. Penelitian ini bertujuan untuk membuktikan dampak penanganan ikan layang yang dijual di pasar. Ikan layang diambil secara acak di Pasar Arumbae dan Pasar Batu Merah Kota Ambon dua kali dalam sehari yakni pada waktu pagi dan waktu sore hari. Teknik penanganan ikan diamati pada saat distribusi dan penanganan di pasar yang meliputi pembersihan, penyimpanan, peletakan ikan serta pemberian es. Jumlah cemaran mikroba pada sampel dihitung menggunakan metode total plate count (TPC). Hasil penelitian menunjukkan bahwa jumlah cemaran mikroba pada ikan yang diambil pada pagi hari lebih rendah dibandingkan pada ikan yang diambil pada sore hari. Teknik penanganan dan penjajakan ikan layang yang diterapkan oleh para pedagang di Pasar Arumbae dan Batu Merah belum diterapkan dengan baik dan belum memperhatikan sistem rantai dingin, sanitasi air, dan tempat penyimpanan ikan selama penjualan. Jumlah cemaran mikroba pada ikan layang segar di Pasar Arumbae dan Pasar Batu Merah pada pagi hari yakni 1,2x10⁴-2,6x104 CFU/g dan 1,5x104-2,6x104 CFU/g sedangkan pada sore hari yaitu 2,4x10⁴-5,0x105 CFU/g dan 4,9x104-4,6x105 CFU/g. Jumlah mikroba pada ikan layang segar di pasar tradisional Kota Ambon masih sesuai standar mutu mikrobiologi ikan segar yaitu maksimal 5x10⁵ CFU/g.

Published: June 2020

In this study, the effect of Ultraviolet (UV) irradiation on induction of individual and total phenolics production on callus cultures of ‘Karaerik’ grape cultivar was investigated. Callus tissues were obtained from the leaves of the cuttings grown in in vitro plants. As a culture medium, Gamborg B-5 was utilized with 0.1 mg L-1 NAA (Naphthaleneacetic acid) and 0.2 mg L-1 Kin (Kinetin). Callus tissues were subcultured twice with 21 days intervals. After the second subculture, 12-day-old callus tissues were exposed to 254 nm UV-C light at 10 cm distance from the source for 10 and 15 min by opening covers of the petri dishes in sterile cabin. After the treatment, callus tissues were incubated under dark conditions. Phenolic compounds were measured at 0, 24th, 48th and 72nd hours. Individual phenolic compounds were analyzed by HPLC (High Pressure Liquid Chromatography) and total phenolic compounds were measured by spectrophotometer. As a result of the study, it was found that UV irradiation was effective for induction the production of phenolic compounds in the callus tissues of ‘Karaerik’ grape cultivar and this effect was closely related to the application time.

Dividend Policy, Personal Taxes and Optimal Capital Structure
Authors: Liu Sheen , Xie Yan Alice
Published: June 2020

This paper puts forward a capital structure model that incorporates the impacts of dividend policy and personal taxes that are commonly ignored by the existing capital structure models. The results show that paying dividends can reduce the tax benefits from issuing debts, which explains why existing capital structure models commonly overestimate leverage ratios. The results further show that as dividend payout increases, leverage ratios and credit spreads increase too. By incorporating the impacts of dividend policy and personal taxes, the capital structure model established in this paper can generate wide range of leverage ratios and credit spreads, which are consistent with what are observed in the real world.

Published: June 2020

Compreendendo-se o Psicólogo do Trânsito como um profissional da área da saúde que atua na promoção de ações voltadas à prevenção, intervenção ou reabilitação no contexto do trânsito, propôs-se uma revisão da literatura nas bases de dados SciELO, LILACS e PePSIC com o objetivo de elucidar em qual nível de atenção da saúde incluem-se as perspectivas atuais da Psicologia do Trânsito. Os resultados mostram que grande parte dos estudos são referentes a estratégias de nível primário, enquanto que, em nível terciário, encontra-se um pequeno foco de estudos. Foi possível constatar que o Psicólogo do Trânsito tem privilegiado ações preventivas em suas práticas e que é preciso ampliar o olhar em nível secundário e ao terciário focando no desenvolvimento de ações de diagnóstico e tratamento das sequelas à saúde psíquica das pessoas que interagem no contexto da mobilidade urbana.

Uma visão geral das teorias do envelhecimento humano
Authors: Nascimento Marcelo De Maio
Published: June 2020

A senescência tem sido foco de interesse para pesquisadores desde o século XIX. Diante disso, foram elaboradas várias teorias para explicar o processo do envelhecimento humano, o fato gerou grupos e subgrupos de teorias. Este manuscrito revisou as principais teorias do envelhecimento e, por conseguinte, sintetizou e classificou as informações existentes. Nossas visões sobre a temática foram apresentadas em um modelo ilustrativo, que consolidou a temática em quatro grupos: i) teorias evolucionárias modernas, ii) teorias programadas, iii) teorias de danos e, iv) teorias combinadas. Ademais, considerações foram feitas sobre a natureza consensual das propostas teóricas apresentadas e suas inter-relações. Nesse contexto, concluiu-se que apesar dos avanços da ciência e do grande número de teorias criadas ao longo dos anos, ainda não existe um entendimento definitivo sobre o processo do envelhecimento, a nível evolutivo, como também é desconhecida a amplitude das analogias dos fatores associados ao processo

Radiomic features are being increasingly studied for clinical applications. We aimed to assess the agreement among radiomic features when computed by several groups by using different software packages under very tightly controlled conditions, which included standardized feature definitions and common image data sets. Ten sites (9 from the NCI's Quantitative Imaging Network] positron emission tomography–computed tomography working group plus one site from outside that group) participated in this project. Nine common quantitative imaging features were selected for comparison including features that describe morphology, intensity, shape, and texture. The common image data sets were: three 3D digital reference objects (DROs) and 10 patient image scans from the Lung Image Database Consortium data set using a specific lesion in each scan. Each object (DRO or lesion) was accompanied by an already-defined volume of interest, from which the features were calculated. Feature values for each object (DRO or lesion) were reported. The coefficient of variation (CV), expressed as a percentage, was calculated across software packages for each feature on each object. Thirteen sets of results were obtained for the DROs and patient data sets. Five of the 9 features showed excellent agreement with CV < 1%; 1 feature had moderate agreement (CV < 10%), and 3 features had larger variations (CV ≥ 10%) even after attempts at harmonization of feature calculations. This work highlights the value of feature definition standardization as well as the need to further clarify definitions for some features.

A Constituição Austeritária
Authors: Sampaio José Adércio Leite
Published: June 2020

O presente trabalho examina como se tem desenvolvido um “novo” constitucionalismo centrado mais no controle fiscal do Estado do que no sistema de direitos fundamentais. As instituições da “velha” simbologia constitucional foram substituídas ou complementadas por outras que mais se adequam a esse “novo” constitucionalismo, baseado na busca da eficiência econômica como legitimação em detrimento do processo democrático como legitimidade. Esse “projeto de significação” constitucional é, ao fim, uma rendição jurídico-política à lógica econômica, tendo como bandeira de triunfo a “Constituição austeritária”, com a centralidade movida dos direitos para o “Estado fiscal” e “autoritário”, e como substratos determinantes as demandas do capitalismo financeirizado.

Authors: Putri Devy Trianne , Marhana Isnin Anang , Jiwangga Dhihintia
Published: June 2020

Background: Pseudomesotheliomatous carcinoma is a rare case of lung cancer with marked pleural extension resembling malignant pleural mesothelioma on diagnostic imaging. One of tool to diagnose lung pseudomesothelioma is by performing thorocoscopy pleural biopsy. Diagnostic thoracoscopy also has a higher sensitivity than pleural fluid cytology and needle biopsy.Case: We report a rare case of pseudomesotheliomatous carcinoma of the lung in a 50-year-old man with asbestos exposure. The patient had complained of dyspnea and chest roentgenogram showed left pleural effusion. Computed tomography (CT) of the chest revealed diffuse irregular left pleural thickening and without a clear initial primary lesion found in both of lung parenchyma, which mimicked pleural mesothelioma. Pleural tissue sampling was performed to obtain definitive diagnosis by video-assisted thoracoscopic surgery. At the operation, the tumor was found to have spread along the pleural surface and primary lesion was not detected in the right lung parenchyma. Immunohistochemically, the tumor was positive for Thyroid Transcription Factor- 1 (TTF-1), but negative for calretinin, P63, and Neuron Specific Enolase (NSE). Final diagnosis was adenocarcinoma of the lung and patient had good clinical response to Gefitinib.Conclusion: Based on the results of clinical studies (images and clinical observations), although pseudomesotheliomatous in patient with asbestos exposure is difficult to distinguish from pleural mesothelioma, we have a case of pseudomesotheliomatous lung diagnosed by a thoracoscopic pleura biopsy. For such cases, thoracoscopic pleural biopsy should be performed at an early stage.

Published: June 2020

Equality and incomparability multi-label ranking have not been introduced to learning before. This paper proposes new native ranker neural network to address the problem of multi-label ranking including incomparable preference orders using a new activation and error functions and new architecture. Preference Neural Network PNN solves the multi-label ranking problem, where labels may have indifference preference orders or subgroups which are equally ranked. PNN is a nondeep, multiple-value neuron, single middle layer and one or more output layers network. PNN uses a novel positive smooth staircase (PSS) or smooth staircase (SS) activation function and represents preference orders and Spearman ranking correlation as objective functions. It is introduced in two types, Type A is traditional NN architecture and Type B uses expanding architecture by introducing new type of hidden neuron has multiple activation function in middle layer and duplicated output layers to reinforce the ranking by increasing the number of weights. PNN accepts single data instance as inputs and output neurons represent the number of labels and output value represents the preference value. PNN is evaluated using a new preference mining data set that contains repeated label values which have not experimented on before. SS and PS speed-up the learning and PNN outperforms five previously proposed methods for strict label ranking in terms of accurate results with high computational efficiency.
A Fully Automated Deep Learning-based Network For Detecting COVID-19 from a New And Large Lung CT Scan Dataset
Authors: Rahimzadeh Mohammad , Attar Abolfazl , Sakhaei Mohammad
Published: June 2020

COVID-19 is a severe global problem that has crippled many industries and killed many people around the world. One of the primary ways to decrease the casualties is the infected person's identification at the proper time. AI can play a significant role in these cases by monitoring and detecting infected persons in early-stage so that it can help many organizations. In this paper, we aim to propose a fully-automated method to detect COVID-19 from the patient's CT scan without needing a clinical technician. We introduce a new dataset that contains 48260 CT scan images from 282 normal persons and 15589 images from 95 patients with COVID-19 infection. Our proposed network takes all the CT scan image sequences of a patient as the input and determines if the patient is infected with COVID-19. At the first stage, this network runs an image processing algorithm to discard those CT images that inside the lung is not properly visible in them. This helps to reduce the number of images that shall be identified as normal or COVID-19, so it reduces the processing time. Also, running this algorithm makes the deep network at the next stage to analyze only the proper images and thus reduces false detections. At the next stage, we propose a modified version of ResNet50V2 that is enhanced by a feature pyramid network for classifying the selected CT images into COVID-19 or normal. If enough number of chosen CT scan images of a patient be identified as COVID-19, the network considers that patient, infected to this disease. The ResNet50V2 with feature pyramid network achieved 98.49% accuracy on more than 7996 validation images and correctly identified almost 237 patients from 245 patients.
A Compartmental Epidemiological Model for the Dissemination of the COVID-19 Disease
Authors: Matsinos Evangelos
Published: June 2020

A compartmental epidemiological model with seven groups is introduced herein, to account for the dissemination of diseases similar to the Coronavirus disease 2019 (COVID-19). In its simplified version, the model contains ten parameters, four of which relate to characteristics of the virus, whereas another four are transition probabilities between the groups; the last two parameters enable the empirical modelling of the effective transmissibility, associated in this study with the cumulative number of fatalities due to the disease within one country. The application of the model to the fatality data (the main input herein) of five countries (to be specific, of those which had suffered most fatalities by April 30, 2020) enabled the extraction of an estimate for the basic reproduction number $R_0$ for the COVID-19 disease: $R_0=4.91(34)$.
Do Pouvoir Neutre ao Poder Moderador: a influência do constitucionalismo inglês no Brasil por meio da teoria de Benjamin Constant
Authors: DalRi Luciene
Published: June 2020

O agravamento das dificuldades políticas resultantes da separação de poderes, durante a Revolução Francesa, fomentou a teoria voltada a um poder específico para preservar a constituição e o equilíbrio entre os poderes. A teoria foi difundida no Brasil, desde a primeira assembleia constituinte, por meio da obra de Benjamin Constant e o preceito de um poder neutro, influenciando o constitucionalismo luso e brasileiro do século XIX. Neste trabalho, questiona-se se a influência da teoria do poder neutro, por meio da obra de Benjamin Constant, seria uma influência francesa e orleanista sobre a constituição brasileira de 1824 ou principalmente um vetor interpretativo do constitucionalismo inglês. Para tanto, analisa-se a teoria de Benjamin Constant sobre o poder neutro, observando a sua aplicação inicialmente em contexto republicano, com ulterior adaptação ao regime monárquico. Posteriormente confronta-se os elementos de sua teoria com o movimento que gerou a constituição brasileira de 1824 e com a doutrina que dela decorre, durante o século XIX. Conclui-se que o constitucionalismo brasileiro recebeu, por meio da obra de Constant, não apenas a influência do constitucionalismo francês, mas que a teoria do poder neutro, que resulta na existência do poder moderador, é um vetor interpretativo do constitucionalismo inglês.

Este artigo versa sobre a possibilidade de responsabilização dos agentes políticos por atos de improbidade administrativa, sem que isso configure ofensa ao princípio do non bis in idem. Há entendimento, não pacífico na doutrina e suscetível de mudança no Supremo Tribunal Federal, de que aqueles agentes que respondem por fatos tipificados na Lei nº 1.079/1950, em razão do comando existente no art. 102 da Constituição Federal, não poderiam responder também pelas condutas descritas na Lei nº 8.429/1992, sob pena de haver dupla penalização pelo mesmo fato, com base na alegação de naturezas jurídicas idênticas das duas legislações, o que aos poucos está sendo superado. O intuito é sustentar exatamente o inverso, ou seja, que tecnicamente é possível (e necessário) a aplicação de ambos os diplomas legais, e que o esvaziamento da lei de improbidade em relação aos fatos e aos agentes que mais necessitam reprimenda, talvez encontra eco na cultura do “jeitinho brasileiro”, de raízes coloniais, com mistura dos espaços públicos e privados. Na realização do presente trabalho, foi utilizada a técnica de pesquisa bibliográfica em uma abordagem qualitativa, abrangendo leitura de doutrinas, teses, artigos e jurisprudência.
To Solution of Contact Problem for Rectangular Plate on Elastic Half-Space
Authors: Bosakov S. V.
Published: June 2020

Until the present time there is no exact solution to the contact problem for a rectangular plate on an elastic base with distribution properties. Practical analogues of this design are slab foundations widely used in construction. A lot of scientists have solved this problem in various ways. The methods of finite differences, B. N. Zhemochkin and power series do not distinguish a specific feature in contact stresses at the edges of the plate. The author of the paper has obtained an expansion of the Boussinesq solution for determining displacements of the elastic half-space surface in the form of a double series according to the Chebyshev polynomials of the first kind in a rectangular region. For the first time, such a representation for the symmetric part of the Boussinesq solution was obtained by V. I. Seimov and it has been applied to study symmetric vibrations of a rectangular stamp, taking into account inertial properties of the half-space. Using this expansion, the author gives a solution to the problem for a rectangular plate lying on an elastic half-space under the action of an arbitrarily applied concentrated force. In this case, the required displacements are specified in the form of a double row in the Chebyshev polynomials of the first kind. Contact stresses are also specified in the form of a double row according to the Chebyshev polynomials of the first kind with weight. In the integral equation of the contact problem integration over a rectangular region is performed while taking into account the orthogonality of the Chebyshev polynomials. In the resulting expression the coefficients are equal for the same products of the Chebyshev polynomials. The result is an infinite system of linear algebraic equations, which is solved by the amplification method. Thus the sought coefficients are found in the expansion for contact stresses.

En este artículo se exponen las estimaciones sobre el peso absoluto y relativo que tiene el cooperativismo en las principales magnitudes agregadas de la economía colombiana. Con estas estimaciones se hace posible descomponer el producto interno bruto y su crecimiento en Colombia incrustando los factores del cooperativismo oportunos. Lo anterior se ha tratado en dos series de tiempo: por una parte, en la serie temporal 2003-2010, periodo de crecimiento del cooperativismo, y, por otra, en la serie 2010-2016, periodo de desaceleración en las grandes cifras cooperativas que, en buena parte, vienen a ser consecuencia de la liquidación e intervención de entidades cooperativas en el país. Para lograr el objetivo de estimar el peso absoluto y relativo que tiene el cooperativismo, se realiza un cuidadoso levantamiento y un procesamiento de la información contable que las cooperativas colombianas reportan a la Confederación de Cooperativas de Colombia o Confecoop, junto con información similar de la Superintendencia de Economía Solidaria y las distintas superintendencias. El artículo concluye que el cooperativismo se ha fortalecido y ha contribuido al crecimiento del estándar material de vida de los colombianos en el periodo bajo estudio. De forma paralela, su valor añadido bruto sobre el total nacional se reduce más que proporcionalmente con respecto a lo que lo hizo su emisión de transferencias sociales en especie ampliadas, lo que demuestra la orientación funcional al beneficio común y al interés general desde una propuesta del institucionalismo económico contemporáneo.

El presente artículo expone la experiencia en la implementación de conceptos y metodologías de innovación social en el desarrollo de ideas de negocio e iniciativas empresariales sostenibles en organizaciones no convencionales. En este caso específico, una comunidad indígena. Si bien la generación de ingresos no es uno de los ejes fundamentales sobre los cuales se guían las actividades de este tipo de organizaciones, con la incorporación de metodologías de diseño e innovación centradas en el hombre se logra que los individuos entiendan los beneficios personales y colectivos que se desprenden del desarrollo de una iniciativa empresarial y tengan una participación más activa en las distintas actividades conducentes a su puesta en marcha. Se realizó un proceso de acompañamiento, a partir de la metodología del doble hexágono, en el que, mediante visitas de campo y la participación activa de los integrantes de la comunidad, se trabajó a fin de lograr procesos de autoorganización y empoderamiento. Con este documento se demuestra que los principios asociados a la innovación social, así como sus metodologías, brindan la posibilidad de acompañar iniciativas empresariales que respeten las condiciones particulares de la comunidad, de modo que es este el elemento que permite incorporar tales iniciativas como parte de su cultura, lo que genera cambios en los hábitos de las personas y facilita así su implementación exitosa.
Hard Times in Canadian Oil Could Be Useful Experience
Authors: Rassenfoss Stephen
Published: June 2020

Combine a pandemic, plunging oil demand and prices, and a deep recession, and then consider how it may change things.

It is not a question Steve MacDonald can answer, but the chief executive officer for Emissions Reduction Alberta (ERA) said it can be a useful way to get people to consider how things can change in un expected ways.

“If you said to someone 4 months ago that oil could go to negative prices, they would say, it’s not going to happen. The range of what could happen is much wider now,” he said.

A recent decision by the $1-trillion Norwegian Wealth Fund to exclude four major oil sands companies saying they have “unacceptably high greenhouse emissions” shows the need for change.

The headlines in Canada have been harsh - the rising death toll from COVID-19, oil prices flirting with zero, job cuts, and the slow and unpredictable timeline to normal life.

“Everything you’re hearing is true. It’s bad,” said Darcy Spady, but the 2018 SPE president is quick to add, “I see a ray of sunshine.”

There is a connection between the bright and the dark sides, and it is forcing leaders from both inside and outside the industry to take a hard look at what works and what does not.

“The pandemic has merely accelerated the disruption that was already occurring in Canada’s oil and gas sector,” wrote Kevin Krausert, the president and chief executive officer of Beaver Drilling, in an essay in a national newspaper, The Globe and Mail.

The essay addressed a long-term future in which the industry undergoes fundamental changes, ranging from research into ways to make hydrogen fuel from gas to drillers digging geothermal wells to provide renewable energy.

But at the moment, it is difficult to get the attention of decision makers about the future.

“It is hard to focus on anything but the here and now. Where the next dollar is coming from rather than from 3-10 years from now,” said Mark Scholz, president of the Canadian Association of Drilling Contractors.

Staying Alive

The dramatic drop in oil demand and prices can kill jobs, companies, and ideas.

MacDonald sees that threat firsthand. “Liquidity is an issue for everybody, cash flow has been a challenge, the ability to secure investors,” are all issues now affecting those trying to scale up promising ideas.

Soon after the economic impact of the sweeping limits that were imposed to slow the spread of COVID-19 became apparent, Emissions Reduction Alberta (ERA) changed its policy to allow increases in progress payments to companies during this period when cash is hard to come by and when some lenders are delaying the release of loan funds, MacDonald said.

By reducing the amount of money held back from progress payments, ERA expects to provide 74 companies with $10 million more in cash in the near term.

The payments may help client companies pay some bills at a time when they are struggling to line up funding and customers for the large-scale tests needed to prove ideas that worked on a smaller scale.

Background: Starch is synthesized during the day for temporary storage in leaves and then degraded during the subsequent night to support plant growth and development. Impairment of starch degradation leads to stunted growth, even senescence and death. The nuclear pore complex is involved in many cellular processes, but its relationship with starch degradation is unclear until now. We previously identified that two Nucleoporin98 (Nup98) genes (Nup98a and Nup98b) redundantly regulate flowering through CONSTANS (CO) independent pathway in Arabidopsis thaliana. The nup98a-1 nup98b-1 double mutant also shows severe senescence phenotypes. Results: We find that Nucleoporin 98 (Nup98) participates in the regulation of sugar metabolism in leaves and in turn involves in senescence regulation in Arabidopsis. We show that Nup98a and Nup98b redundantly function in the different steps of starch degradation and the nup98a-1 nup98b-1 double mutant accumulates more starch than wild type plants and has a severe early senescence phenotype compared to wild type plants. The expression of marker genes related to starch degradation is impaired in the nup98a-1 nup98b-1 double mutant, and marker genes of carbon starvation and senescence express earlier and in higher abundance in the nup98a-1 nup98b-1 double mutant than in wild type plants, suggesting that abnormality of energy metabolism is the main cause of senescence of the nup98a-1 nup98b-1 double mutant. Addition of sucrose to the growth medium rescues early senescence phenotypes of the nup98a-1 nup98b-1 mutant. Conclusions: Our results provide a line of evidence on a novel role of the nuclear pore complex in energy metabolism related to growth and development, in which Nup98 functions in starch degradation conferring growth regulation in Arabidopsis.
