Authors: Lisdawati  , Faisal Ardiansyah
Published: March 2021

Financial performance can be a future or prospect whose development potential is very good for company growth. Working capital is a separate and fundamental problem that company managers often face in managing equity and assets. In contrast, Receivables, which are part of the working capital component, have a turnaround or cycle related to the sale of commodities, cash flow, and cash receipts. The turnover describes good financial condition. The study population used financial statement data at PT AKR Corporindo Tbk in 2005-2019. The purpose of this research is to specifically examine and prove the measurement of Working Capital and Accounts Receivable Turnover and its impact on Return On Assets empirically. Data analysis used multiple regression analysis with Statistic / Data Analysis software STATA MP14 Version. This study indicates that the turnover of working capital and accounts receivable turnover does not increase Return on Assets either partially or simultaneously. The Return On Assets contribution is influenced by 16.88 percent of the Working Capital Turnover, Accounts Receivable Turnover, and Company Size factors as control variables.

Coffee farmers as Green MSMEs can apply SDG-based global value chains (GVC) in order to open up a wider share of the export market. During the 2009-2018 period, there was a significant decline in the share of Indonesia's coffee exports, but on the other hand, the impact on the formation of the GDP of plantation crops seemed insignificant. The study attempts to map this problem by analyzing the relationship between the variables that play a role in the formation of GDP (as the dependent variable), namely the volume of coffee production, the export value of coffee, the export price of coffee, and the MSME investment credit during the 2009-2018 period. This research uses a quantitative based approach to obtain multiple linear regression models that can map research problems. Based on statistical tests, the research variables have a positive and significant contribution to the increase in the GDP of plantation crops. The implication of the results is the trend of declining exports substituted by the booming demand for coffee in the country supported by MSME investment credit. The application of GVC can be one strategy to increase the share of coffee exports again.

Negócios Jurídicos Processuais: O novo protagonismo das partes dentro da relação processual e o papel do juiz
Authors: Bucco Bruna Maiolino
Published: March 2021

O Direito Processual brasileiro enfrentou diversas modificações e ampliações com a entrada em vigor do Novo Código de Processo Civil no ano de 2016. Alguns institutos já existentes foram revisitados, de modo a se adequarem aos preceitos fundamentais que passaram a ser expressamente previstos no CPC/15. Dentre eles está o negócio jurídico processual. O CPC/15 manteve os negócios processuais típicos, já presentes no CPC/73, e alargou o espectro, trazendo no art. 190 do CPC previsão sobre a possibilidade da realização de convenções processuais atípicas. Por essa razão, em decorrência do surgimento desta nova espécie de ato, nosso estudo objetivou, através da análise e interpretação de bibliografias disponíveis sobre o tema, investigar a participação do juiz frente a dilação da autonomia e da liberdade dada às partes no processo. Conseguimos identificar que, em algumas situações, a manifestação de vontade do magistrado se mostra imprescindível para que o negócio processual seja válido, sem que isso represente afronta ao art. 190 do CPC/15, nem tão pouco ao princípio do auto regramento da vontade das partes.

Influence of integrated use of cotton seed oilcake and mustard oilcake with chemical fertilizers on growth, yield and nutritional quality of rice
Authors: Yasmin S , Hashem MA , Hoque TS
Published: March 2021

Cotton seed oilcake and mustard oilcake are excellent and high quality organic manures enriched with essential nutrient elements. A field experiment was carried out at the Soil Science Field Laboratory of Bangladesh Agricultural University, Mymensingh during boro season of 2019 to investigate the influence of cotton seed oilcake and mustard oilcake on yield attributes, yield, nutrient content and uptake by rice cv. BRRI dhan29. The experiment was laid out in a Randomized Complete Block Design (RCBD) with four replications and seven treatments viz. T1: control, T2: 100% Recommended Fertilizer Dose (RFD), T3: 50% RFD, T4: 50% nitrogen (N) from RFD + 50% N from cotton seed oilcake, T5: 50% N from RFD + 50% N from mustard oilcake, T6: 50% N from RFD + 25% N from cotton seed oilcake + 25% N from mustard oilcake, T7: 50% N from cotton seed oilcake + 50% N from mustard oilcake. The maximum values of all the yield components viz. plant height, panicle length, number of effective tillers hill-1 and filled grains panicle-1 and yields (grain and straw) were found in treatment T2. The highest content and uptake of nutrients – N, P, K and S were also recorded in T2. The performance of T4 and T2 was statistically similar in producing yield parameters, grain and straw yields, nutrient contents and uptake by rice. Among the integrated approaches, the performance of T4 was the best as it produced the second highest grain yield of 6.24 t ha-1 and straw yield of 8.17 t ha-1 with higher nutritional improvement of rice. Application of cotton seed oilcake compensated up to 50% of chemical fertilizer. Therefore, considering the significance of organic manures and soil health, cotton seed oilcake should be considered for application in association with chemical fertilizers for yield enhancement and nutritional improvement of rice.

In search of a co-operation ecosystem for collaborative planning and co-governance
Authors: Jarenko Karoliina
Published: March 2021

Contemporary urban planning with linear administrative processes, based on the ideals of predictability and control, have come to its end. Even public participatory planning has struggled to incorporate the input of engaged citizens to urban development and the co-governance of common resources. Self-organized actions of urban activist and mundane everyday life have not been sufficiently addressed in the participatory urban planning processes. However, local initiatives and even the temporary use of urban space have been seen as a contribution to urban development. The problem is that so far we do not have much knowledge about the co-operation ecosystem required for new approaches to urban planning, such as the Expanded urban planning. In this article, I examine two case studies, on the basis of which a co-operation ecosystem for Expanded urban planning is outlined. I argue that such an ecosystem for co-operation can significantly help cities integrate self-organized citizen initiatives to urban and community development. It might, however, also require planners to take a stronger role in enhancing a culture of participation.

Published: March 2021

В Вооруженных Силах Украины продолжается работа по повышению эффективности оборонного планирования и управления оборонными ресурсами. Алгоритм оборонного планирования развития Вооруженных Сил Украины шаг за шагом использует результаты анализа опыта ведущих стран мира, которые перешли от планирования в области обороны на основе угроз, к оборонному планированию, ориентированному на приобретение войсками (силами) возможностей, необходимых для выполнения возложенных на них задач. Перечень задач Вооруженных Сил Украины определяется на основе вероятных сценариев их применения. Одним из ключевых моментов эффективного планирования применения Вооруженных Сил по соответствующему сценарию есть реальное и обоснованное определение объемов необходимых оборонных ресурсов (человеческих, материально-технических, финансовых). Трансформация системы оборонного планирования Украины к стандартам НАТО, а также применение метода планирования на основе возможностей в Генеральном штабе Вооружённых Сил Украины формируют необходимость совершенствования существующих методических подходов по определению потребностей в оборонных ресурсах для применения Вооруженных Сил Украины по тем или иным сценариям их применения. Также актуальной задачей сегодня есть необходимость оценивания достаточности реальных экономических и временных возможностей государства по обеспечению применения Вооружённых Сил за предварительно разработанными сценариями их применения. Общий алгоритм оценки стоимости оборонных ресурсов для применения Вооруженных Сил Украины в конфликтах различной интенсивности должен учитывать экономические реалии развития национальной экономики страны. В статье авторы предложили свои взгляды по совершенствованию существующих подходов к проведению расчетов объемов необходимых оборонных ресурсов, порядок и содержание оценки их стоимости по соответствующим сценариям применения Вооруженных Сил с целью дальнейшей оценки экономических возможностей государства по их обеспечению. Основными результатами статьи является порядок оценки стоимости выполнения поставленных Вооруженным Силам Украины задач и стоимости ведения военных действий различной интенсивности, а также общий алгоритм проведения расчетов.

Published: March 2021

Стаття присвячена вирішенню проблем забезпечення енергією промислових галузей і об’єктів, транспортних засобів, особистих потреб людини та взагалі енергетичної безпеки майбутніх поколінь людства.

Проведений аналіз наукових робіт в цій галузі і визначено, що ставка робиться на видобуток та використання альтернативних видів енергії, що не змозі забезпечити все збільшуючи потреби людства.

Пропонуються концептуальні підходи щодо отримання енергії на основі наукової гіпотези отримання енергії без витрати енергоносіїв. В цьому випадку, традиційні теплова, електрична, гравітаційна, світлова, звукова, вітрова, гідравлічна, біологічна і інші види енергії є лише способами передачі, транспортування енергії, а не самою енергією. Енергія характеризується величинами коливальних параметрів хвиль випромінювань і займаним простором з певною щільністю енергії.

На основі цих підходів відбувається активація палива, його енергезація, тобто підвищення енергетичної ефективності теплом відпрацьованих газів. Залежно від видів палив і пристроїв, де вони використовуються, при одному і тому ж кінцевому результаті витрата енергоносіїв, можливо, зменшена на 10 – 80 %. При цьому забезпечується повне згорання кожного окремого компоненту палива. Одночасно вирішуються не тільки енергетичні завдання, але і вельми складні екологічні проблеми.

В подальшому пропонується обґрунтувати вимоги до приладів перетворення видів енергії для цих перспективних двигунів.
O arquivo do inventário dos marginais da diferença na pesquisa curricular brasileira

Published: March 2021

Há mais de três décadas, somos testemunhas da contaminação da perspectiva da Filosofia da Diferença, encabeçada por Deleuze & Guattari, assim como a dos pensadores reconhecidos como os malditos nas pesquisas do campo da psicanálise, da antropologia, dos estudos de gênero, da educação e do campo curricular. Nesse sentido, o movimento desta escrita acontece frente à necessidade de se registrar essa memória formativa, assim como suas rizomáticas linhas de conexão, pois entende-se que ainda se estabelecem no cosmos em um estado espectral. Ao fazer esse movimento, optamos pela metodologia do arquivo, tal qual estabelecida por Derrida (2001), no sentido de problematizar as múltiplas possibilidades de se conhecer tais encontros.

Esta pesquisa teve como objetivo analisar as percepções de estudantes do terceiro ano do ensino médio em cidades do brejo paraibano acerca do processo de aprendizagem na disciplina de Química. Para tanto, compreende-se que o aprendizado de Química é fundamental para o entendimento de vários fenômenos e transformações que ocorrem no nosso cotidiano, possibilitando a relação teoria e prática de vários conceitos químicos. Assim, para que esse tipo de aprendizagem ocorra, é necessário que o ensino possibilite ao educando ir além da memorização de conteúdo, pois o processo de ensino e aprendizagem deve acontecer dentro de uma perspectiva construtiva. Para construção dos dados, realizamos um estudo de natureza quantitativa, interpretativa e descritiva, com quantificação de dados. O levantamento de dados ocorreu por meio da aplicação de um questionário composto por perguntas objetivas. A pesquisa foi realizada em quatro municípios situados no brejo paraibano, sendo desenvolvidas em escolas estaduais dos municípios de Arara, Areia, Bananeiras e Solânea. Os resultados alcançados apontam a necessidade de mudanças metodológicas e didáticas que possam aprimorar cada vez mais a aprendizagem de conceitos químicos. Ademais, destacamos a necessidade do uso de diferentes abordagens de ensino, tais como o uso da contextualização e da experimentação como estratégias fundamentais para o melhor aprendizado dos discentes. Compreende-se que o ensino apoiado, a partir dessas perspectivas possibilita uma maior motivação dos estudantes em aprender Química, pois além de explorar conteúdos relacionados ao seu cotidiano, tornar-se-ão cidadãos capazes de desenvolver o senso crítico e reflexivo.

A cirurgia parendodôntica constitui um conjunto de procedimentos que têm como objetivo reparar complicações que não puderam ser solucionados através da endodontia convencional, ou quando essa não é passível de execução. Este estudo teve como objetivo descrever o caso clínico de uma cirurgia parendodôntica associada a terapia fotodinâmica no elemento dental 11. O caso foi conduzido realizando o acesso ao sistema de canais radiculares de forma retrograda. Foram realizadas: antissepsia intra/ extra bucal, anestesia infiltrativa, retalho para acesso, confecção da loja óssea, apicectomia, retroinstrumentação, terapia fotodinâmica, retrobturação, preenchimento da loja óssea, reposicionamento do retalho e sutura com acompanhamento tomográfico de feixe cônico de 4 anos. Concluímos que, a associação do ato cirúrgico com a aplicação de laser de baixa potência através da terapia fotodinâmica potencializou a desinfecção e a eliminação de bactérias persistentes ao fracasso do tratamento endodôntico anterior, propiciando benefícios adicionais ao paciente quando comparado à técnicas cirúrgicas convencionais.

This was aimed to evaluate the effects of plant arrangements and cutting systems on the yield and quality of dual purpose wheat. The present study was conducted in the years 2015, 2016 and 2017 in Frederico Westphalen, belonging to the state of Rio Grande do Sul. The dual purpose wheat genotype used was BRS Tarumã. For this, five sowing densities were used, namely: 75, 150, 225, 300 and 375 seeds per square meter. The analysis of variance revealed significance for the interaction sowing density x cutting systems x chemical quality for the variables dry matter per hectare, lipids, digestible fiber in acid detergent, lignin, cellulose, mineral matter, total carbohydrates and non-fibrous carbohydrates. The positive effects on yield and bromatological quality of the forage are obtained by arranging plants and cutting systems through the sowing density of 300 to 375 seeds per meter with the practice of up to two cuts in dual purpose wheat. Superior dry matter per unit area was observed in the second cut, which was defined by the stimulation of tillering, regrowth and split nitrogen fertilization. Since, the superior bromatological quality is determined by the magnitude of non-fibrous carbohydrates in the forage.
The effects of 17β estradiol, 17α estradiol and progesterone on oxidative stress biomarkers in ovariectomized female rat brain subjected to global cerebral ischemia
Authors: Ozacmak VH , Sayan H
Published: March 2021

Neuroprotective effects of estrogens and progesterone have been
widely studied in various experimental models. The present study
was designed to compare possible neuroprotective effects of
17alpha-estradiol, 17beta-estradiol, and progesterone on
oxidative stress in rats subjected to global cerebral ischemia.
Global cerebral ischemia was induced in ovariectomized female
rats by four vessel occlusion for 10 min. Following 72 h of
reperfusion, levels of malondialdehyde (MDA, oxidative stress
marker), and reduced glutathione (GSH, major endogenous
antioxidant) were assessed in hippocampus, striatum and cortex
of rats treated with either 17alpha-estradiol, 17beta-estradiol,
progesterone or estradiol + progesterone beforehand. Steroid
administration ameliorated ischemia-induced decrease in GSH
and increase in MDA levels. Our data offers additional evidence
that estrogens and progesterone or combination of two exert a
remarkable neuroprotective effect reducing oxidative stress.

Published: March 2021

Visfatin is an adipose tissue-derived hormone shown to correlate
with visceral fat mass in patients with obesity. Its possible role in
patients with different types of eating disorders is unknown. We
measured fasting serum levels of visfatin and leptin and
surrogate measures of insulin sensitivity in 10 untreated patients
with anorexia nervosa (AN), 10 untreated patients with bulimia
nervosa (BN) and 20 age-matched healthy women (C) to study
the possible role of visfatin in these disorders. Patients with AN
had severely decreased body mass index (BMI) and body fat
content. BMI of BN group did not significantly differ from that of
C group, whereas body fat content of BN group was significantly
lower compared to C and higher compared to AN group,
respectively. Serum glucose levels did not significantly differ
among the groups studied, whereas serum insulin and leptin
levels and HOMA index were significantly decreased in AN group
relative to both C and BN group. In contrast, serum visfatin levels
in both patients with AN and BN did not differ from those of C
group. We conclude that circulating visfatin levels are not
affected by the presence of chronic malnutrition in AN or
binge/purge eating behavior in BN.

Published: March 2021

Compression of the rostral ventrolateral medulla oblongata
(RVLM) by an abnormally located artery is regarded as one
possible cause of arterial hypertension. There exists a limited set
of data suggesting that increased sympathetic activity in patients
with RVLM compression may lead to arterial hypertension.
Accordingly, we decided to assess the sympathetic activity in
patients with severe arterial hypertension and to investigate any
correlation with the presence of RVLM compression. Sixty-four
patients with severe arterial hypertension were enrolled in our
study. Sympathetic activity was evaluated using 24-hour urinary
norepinephrine as measured by high-pressure liquid
chromatography with electrochemical detection. The presence of
RVLM compression was assessed with magnetic resonance
imaging. Neurovascular compression of the RVLM was identified
in 40 patients, 27 of whom presented left-sided compression.
Twenty-four hour urinary norepinephrine averaged
263.6±135.9 nmol in patients with neurovascular compression -
255.6±137.3 nmol in those with left-sided compression and
251.6±138.5 nmol in patients without RVLM compression. We did
not identify any increase in urinary norepinephrine in patients
with severe arterial hypertension and neurovascular compression
of the RVLM. Our results do not support the hypothesis that
neurovascular compression of RVLM may exhibit a
sympathetically mediated increase in blood pressure.

Damage-associated molecular patterns (DAMPs) are a group of immunostimulatory molecules, which take part in inflammatory response after tissue injury. Kidney-specific DAMPs include Tamm-Horsfall glycoprotein, crystals, and uromodulin, released by tubular damage for example. Non-kidney-specific DAMPs include intracellular particles such as nucleus [histones, high-mobility group box 1 protein (HMGB1)] and cytosol parts. DAMPs trigger innate immunity by activating the NRLP3 inflammasome, G-protein coupled class receptors or the Toll-like receptor. Tubular necrosis leads to acute kidney injury (AKI) in either septic, ischemic or toxic conditions. Tubular necrosis releases DAMPs such as histones and HMGB1 and increases vascular permeability, which perpetuates shock and hypoperfusion via Toll Like Receptors. In acute tubular necrosis, intracellular abundance of NADPH may explain a chain reaction where necrosis spreads from cell to cell. The nature AKI in intensive care units does not have preclinical models that meet a variation of blood perfusion or a variation of glomerular filtration within hours before catecholamine infusion. However, the dampening of several DAMPs in AKI could provide organ protection. Research should be focused on the numerous pathophysiological pathways to identify the relative contribution to renal dysfunction. The therapeutic perspectives could be strategies to suppress side effect of DAMPs and to promote renal function regeneration.

Objective: This study aims to determine the acceptability of a COVID-19 vaccine among healthcare workers in Saudi Arabia and the factors affecting their intention to accept the vaccine.

Methods: The study used data from an online cross-sectional survey that was conducted in Saudi Arabia between 8 December 2020 and 14 December 2020. This study employed bivariate and multivariable regression analyses. The bivariate was used to describe and tabulate the frequency of all the variables, including the sociodemographic characteristics, the risk perception and the acceptance of the COVID-19 vaccination and a chi-squared test of independence was calculated. Multivariable logistic regression models were employed to examine and identify the factors associated with an intention to have the COVID-19 vaccination and the factors associated with its immediate acceptance.

Results: Of the total of 736 healthcare workers who began the online questionnaire, 673 completed it (a 91.44% completion rate). Among the study participants, 50.52% were willing to have the COVID-19 vaccine, of which 49.71% intended to have the vaccine as soon as it becomes available in the country, while 50.29% would delay until the vaccine's safety is confirmed. Being a male healthcare worker, perceiving a high risk of infection, and believing that the COVID-19 vaccine should be compulsory for all citizens and residents in the country increased the probability of intention to vaccinate against COVID-19 and the probability of accepting the COVID-19 vaccination as soon as possible.

Conclusion: This study calls for more health-related education among healthcare workers to alleviate any fears that might be associated with the COVID-19 vaccine.
The Thalamus as a Blackboard for Perception and Planning
Authors: Worden Robert , Bennett Max S. , Neacsu Victorita
Published: March 2021

It has been suggested that the thalamus acts as a blackboard, on which the computations of different cortical modules are composed, coordinated, and integrated. This article asks what blackboard role the thalamus might play, and whether that role is consistent with the neuroanatomy of the thalamus. It does so in a context of Bayesian belief updating, expressed as a Free Energy Principle. We suggest that the thalamus-as-a-blackboard offers important questions for research in spatial cognition. Several prominent features of the thalamus—including its lack of olfactory relay function, its lack of internal excitatory connections, its regular and conserved shape, its inhibitory interneurons, triadic synapses, and diffuse cortical connectivity—are consistent with a blackboard role.Different thalamic nuclei may play different blackboard roles: (1) the Pulvinar, through its reciprocal connections to posterior cortical regions, coordinates perceptual inference about “what is where” from multi-sense-data. (2) The Mediodorsal (MD) nucleus, through its connections to the prefrontal cortex, and the other thalamic nuclei linked to the motor cortex, uses the same generative model for planning and learning novel spatial movements. (3) The paraventricular nucleus may compute risk-reward trade-offs. We also propose that as any new movement is practiced a few times, cortico-thalamocortical (CTC) links entrain the corresponding cortico-cortical links, through a process akin to supervised learning. Subsequently, the movement becomes a fast unconscious habit, not requiring the MD nucleus or other thalamic nuclei, and bypassing the thalamic bottleneck.

Published: March 2021

Purpose: Several studies have demonstrated an advantage of 68Ga-PSMA-PET/CT as staging modality for detection of prostate cancer (PCa) metastases. Data concerning metastatic manifestation and impact on PCa development of mesorectal lymph nodes (MLN) is limited. Our investigation describes MLN metastases as index lesion in 68Ga-PSMA PET/CT imaging for recurrent PCa.

Methods: Twelve PCa patients with biochemical recurrence (BCR) after primary therapy who prospectively underwent a baseline 68Ga-PSMA-PET/CT initially showed MLN metastases. Eight of these patients received a follow-up 68Ga-PSMA-PET/CT to evaluate treatment response and further evolution. Prostate-specific antigen (PSA)-levels, changes in PSMA-uptake of MLN metastases and further 68Ga-PSMA PET/CT findings were recorded.

Results: Median PSA at the first 68Ga-PSMA-PET/CT was 5.39 ng/ml. In all patients therapeutic management changed after the first 68Ga-PSMA-PET/CT. Androgen deprivation therapy (ADT) was initiated in seven of eight patients, one patient restarted initial ADT. Three patients additionally received salvage radiation therapy (sRT) including the prostatic lodge and docetaxel chemotherapy was started in one case. At follow-up, a decrease of PSA-level was detected in all patients (median 2.05 ng/ml) after median 10 months. In six of eight patients we observed a decrease or complete regress of PSMA-uptake in MLN in the follow-up 68Ga-PSMA-PET/CT.

Conclusion: MLN metastases detected by 68Ga-PSMA-PET/CT seem to be a relevant localization of tumor manifestation and may serve as index lesion in the treatment of recurrent PCa. Besides the known oncological benefits of ADT and sRT, in case of sole MLN metastases individualized therapy like salvage lymphadenectomy or RT with a defined radiation field could be options for these patients.

This article substantiates the need to find and implement innovative tools to improve the efficiency of the domestic system for energy sector control. The authors determined that energy policy renewal should consider Ukraine’s commitments to transition to a carbon-neutral economy. The systematization of scientific achievements shows that one of the priority tasks is to minimize the gaps in the energy efficiency of the national economy. It is established that, despite the significant scientific achievements in this area, the scientific community has not adopted a single approach to assessing energy efficiency yet. The purpose of this article is to assess the energy efficiency gaps in the national economy, in order to identify their peak values and the factors causing them, and appropriate mechanisms to minimize them. The energy efficiency gaps are assessed using frontal analysis and Shepard’s energy distance function. Analytical data from the World Bank, the Swiss Institute of Economics, and the International Energy Agency form the information base. The study applied software package Stata 14 for calculation the energy efficiency gaps for Ukraine for 2002–2019. The study applied the Shepard’s function translogarithmic, stochastic frontier analysis for the assessment of energy efficiency gaps. According to the study results, the average level of energy efficiency gaps is 0.12, and their values became the largest in 2009 and 2015. First of all, this is due to the impact of the global financial crisis and the escalation of military–political conflicts. The growing dynamics of the energy efficiency gaps level is due to the excess of the negative effect of increasing exports of primary energy resources and inefficient technologies for their processing over the positive impact of energy-efficient innovation imports. In this case, the government should provide a proactive strategy for creating a positive investment climate, in order to attract additional financial resources for extending green innovations and popularizing the green style and cultivate the energy safety behavior in society.
