Political Economy is a theory or study of the role of public policy in influencing economic and social welfare in political relations (Merriam, 2018). According to Investopedia Political Economy is the study of production and trade, and its relation with costums, government and law. But in determining the amount of BPIH also influenced by many factors, such as world oil prices and the exchange rate of the rupiah. In relation to the determination of BPIH, this is inseparable from fiscal policy. Fiscal policy is a government instrument to influence the economy in the context of realizing national development, which is elaborated through the management of the National Budget (Republic of Indonesia, 2015).

Authors: Azwar Azwar
Published: July 2020

ABSTRACTPaving block is a building material used as a layer or structure of roads other than asphalt or concrete. Now many consumers choose paving blocks compared to other pavements such as concrete or asphalt. Some research and experiments in the field of concrete are done as an effort to improve the quality of paving blocks, increasing the level of destruction of paving blocks from the results of research and experiments intended to answer the increasingly high demands on the use of paving blocks and overcome the obstacles that often occur in the implementation of work in the field. The use of added materials can help solve these problems. For this reason, new innovations for substituting concrete composites from natural resources and renewable natural waste are needed. in daily life.

Authors: Doulberis Michael , Papadimitriou Kasiani , Papaefthymiou Apostolis , Kountouras Jannis , Polyzos Stergios A.
Published: July 2020

Pooled prevalence of nonalcoholic fatty liver disease (NAFLD) globally is about 25%. Nonalcoholic steatohepatitis (NASH) with advanced fibrosis has been linked with substantial morbidity and mortality, without having to-date any licensed treatment. C-C chemokine receptor (CCR) antagonists have been investigated as candidates for the treatment of NASH. Inhibition of CCR2 is expected to mitigate hepatic inflammation, through reducing the activation of Kupffer cells, as well as the infiltration of monocytes and macrophages into the liver. Inhibition of CCR5 is expected to mitigate hepatic fibrogenesis, through impairing the activation of hepatic stellate cells, as well as to mitigate hepatic inflammation, through impairing the activation of Kupffer cells and macrophages. Cenicriviroc (CVC) is the first in class, dual inhibitor of CCR2 and CCR5. After exhibiting favorable results in animal models, CVC was shown to be beneficial in NASH patients with more severe fibrosis at a phase 2b trial (CENTAUR) and is currently at a phase 3 clinical trial (AURORA). Apart from CVC, other CCR5 mono-antagonists, such as maraviroc, are under evaluation in clinical trials with human immunodeficiency virus patients with NAFLD. The aim of this review was to summarize existing evidence on CVC and other CCR antagonists in NASH patients, primarily focusing on their clinical efficacy and safety.

Informal Self-Help Financial Groups and Micro-enterprise Development in Tivland, Benue State Nigeria
Authors: Aan James T. , Famave Vershima G.
Published: July 2020

Abstract:- Tivland is not developed. About 70% of 3.9 million population in Tivland are small-holder farmers and micro-entrepreneurs who are funded by informal self-help financial groups (ISHFGs), which are not supported by external funding. Using in-depth interviews and participant observation methods, the study sought to identify the major types of ISHFGs in Tivland, how they generate funds, how they are sustained, their role in micro-enterprise development, and their challenges. The study revealed that there are three major types of ISHFGs in Tivland. They generate funds through savings deposits and interests on loans. They are sustained by group trust/cohesion. They have created easy access to micro-credit, and have empowered members for in income generating activities. Their major challenges are limited funds, bad leadership, no networks and external funding. The study concludes that ISHFGs in Tivland need networks for external funding, management/leadership trainings and close monitoring and evaluation of their operations

Uma revisão sistemática sobre a aprendizagem baseada em problemas no ensino de Ciências
Authors: Da Silva Judimar Teixeira , Da Silva Ivoneide Mendes
Published: July 2020

A aprendizagem baseada em problemas é uma metodologia que utiliza o problema da vida real para direcionar o processo de ensino e aprendizagem. O objetivo deste artigo foi construir um estudo de Revisão Sistemática para identificar um breve estado da arte da utilização do método PBL no processo de ensino e aprendizagem no Ensino das Ciências na educação básica. A revisão sistemática (RS) é um método de análise eficaz por permitir emergir tendências de novas pesquisas no campo acadêmico. Para isso, realizou-se uma RS de artigos científicos em eventos e revistas na área de educação, e teses e dissertações em biblioteca digital no período de 2008 a 2018, utilizando os termos Problem based learning (PBL) e Aprendizagem baseada em problemas. Considerou-se 32 produções acadêmicas elegíveis, submetidas à leitura integral e a análise de conteúdo. Os resultados apontam o potencial da PBL na educação básica, podendo ser aplicada na construção de conceitos científicos, entretanto quando se trata de formação de professores os cursos de curta duração em universidades ainda é o modelo predominante.

Hableánytól a Maccabi Játékokig – avagy eseménydús nyarat tudhat maga mögött a Terrorelhárítási Központ
Authors: Hornyik Zsuzsanna
Published: July 2020

Probably there is nobody who has not heard about the accident of the river trip boat Hableány last May. Practically parallel to that – in the evening of the following day – the Minister for Interior entitled the leader of the Counter Terrorism Centre to control and coordinate rescue operations. This rescue lasting thirteen days meant a very complicated and for the Centre an unusual task considering that this kind of rescue actions are not part of assignment and scope of the Counter Terrorism Centre. But what does it all mean in the practice, about that talked to János Hajdu, police major general and director-general of the Counter Terrorism Centre, Dr. Zsuzsanna Hornyik.

Rotationally Inelastic Collisions of CN− with He: Computing Cross Sections and Rates in the Interstellar Medium
Authors: González-Sánchez L , Mant Barry P. , Wester Roland , Gianturco Franco A.
Published: July 2020

A newly calculated ab initio potential energy surface is used to compute collision-driven state-changing cross sections and rate coefficients over a range from 5 to 100 K for CN−(1Σ), the smallest anion detected in the interstellar medium, interacting with He, an abundant species in this environment. We compare our presently computed rate coefficients with those previously published for the similar and important systems CN–He, CN-H2, and CN−–H2 to illustrate the broader network of inelastic, state-changing processes for these four systems. We also discuss the size-scaling effects that occur when changing partners from He to H2. We further analyze the differences in size between collision-driven rate coefficients when going from neutral CN to its anion. All the present results are discussed in detail, to provide accurate and realistic data for chemical networks that wish to include the CN− anion in their modeling of astrochemical environments.

There was also found link between putting Guards on this list and new American strategy of "maximal pressure" against Iran.
A checklist of vascular plants of the W National Park in Burkina Faso, including the adjacent hunting zones of Tapoa-Djerma and Kondio
Authors: Nacoulma Blandine , Schmidt Marco , Hahn Karen , Thiombiano Adjima
Published: July 2020

The W National Park and its two hunting zones represent a unique ecosystem in Burkina Faso for biodiversity conservation. This study aims at providing a detailed view of the current state of the floristic diversity as a baseline for future projects aiming at protecting and managing its resources. We combined intensive inventories and distribution records from vegetation plots, photo records and herbarium collections.

This is the first comprehensive checklist of vascular plants of the Burkina Faso part of the transborder W National Park. With 721 documented species including 19 species new to Burkina Faso, the Burkina Faso part of the W National Park is, so far, the nature reserve with most plant species in Burkina Faso. To a large extent, this may be assigned to its high habitat diversity and moderate degree of disturbance, but also to a relatively large area within an even larger complex of neighbouring protected areas, as well as comprehensive spatial, ecological and seasonal sampling efforts. However, as a World Heritage Site and regarding the current general context of insecurity, the W National Park and the entire WAP Complex require more international attention in order to ensure its conservation.

Published: July 2020

Seven trichodorid species including a new one (Trichodorus hangzhouensissp. nov., T. nanjingensis, T. pakistanensis, T. cedarus, Paratrichodorus porosus, Nanidorus renifer and N. minor) were recovered from the rhizosphere of different hosts in 13 provinces of China. Each of the recovered species was characterized based on morphology and molecular data using rRNA gene sequences. Trichodorus hangzhouensissp. nov. is characterized by its males having medium-sized onchiostyle (46–49 µm) and three ventromedian cervical papillae (CP) anterior to the secretory-excretory (S-E) pore, CP1 located opposite the anterior part of isthmus, S-E pore opposite the isthmus or anterior end of pharyngeal bulb, spicules slightly ventrally curved, relatively small, 33.2 (32.0–34.5) µm long, wider slightly marked capitulum, lamina partially striated without bristles at striation; and females having rounded triangular sclerotized vaginal pieces with tips directed towards vulva, 1.5–2.0 µm sized, at about 1 µm apart, vulva pore-like in ventral view. Phylogenetic analysis based on D2-D3 28S rRNA gene sequences differentiated the new species among Trichodorus species from Europe, Asia and USA which formed a large clade. A review of the distribution of Trichodorus, Nanidorus and Paratrichodorus species revealed that T. cedarus, T. nanjingensis, T. pakistanensis and P. porosus are the most widespread species recorded from different provinces of China. This is the first extensive study of trichodorid species occurring in China.
Reconnaissance et validation des acquis de la mobilité géographique et de l’apprentissage à distance : virtualité ou réalité ?
Authors: Blons-Pierre Catherine
Published: July 2020

Nous avions constaté dans une étude précédente (Blons-Pierre, 2017) combien il était difficile pour les étudiants de faire reconnaître toutes les compétences acquises lors d’un séjour de mobilité à l’étranger, notamment celles qui échappent au champ de l’apprentissage formel. Depuis cette publication, la mobilité géographique et physique des étudiants et des apprentis s’est encore étendue ainsi que les possibilités de l’enseignement à distance via les nouvelles technologies, à tel point qu’il est possible, à l’heure actuelle, de se demander si l’enseignement dématérialisé massif à distance ne serait pas la solution qui permettrait un accès universel aux savoirs et savoir-faire et résoudrait en même temps les problèmes économiques et humains liés à la massification des effectifs des étudiants présents physiquement dans les universités. Cependant, que l’on se tourne vers l’un ou l’autre de ces types d’apprentissages à distance, demeure le problème de la reconnaissance et de la validation des acquis obtenus hors du cadre de l’apprentissage formel.Nous proposons ici d’examiner sous quelles conditions et avec quels outils les acquis de la mobilité géographique et de l’enseignement à distance massif pourraient être reconnus et validés, que ce soit dans un contexte académique ou professionnel. Pour ce faire nous adopterons le cadre méthodologique de la recherche de synthèse, qui s’appuie sur des concepts scientifiques et des formes de discours liés à des pratiques ou à des instructions officielles.
Les métaux critiques pour l’économie française
Authors: Lefebvre Gaétan
Published: July 2020

La qualification de critique donnée à un métal découle d’une évaluation, et donc d’un niveau de perception donné. Un métal critique combine de forts risques de déficit en matière d’approvisionnement avec de forts impacts en cas de non disponibilité. Pour les industriels français, les sources de risques sont nombreuses. Ils peuvent provenir de goulots d’étranglement dans la chaîne d’approvisionnement, d’une compétition exacerbée entre secteurs ou encore d’une impossibilité de substitution de la substance en question pour un usage précis, ou d’une indisponibilité géologique ou technique. Les études de criticité, dont celles réalisées par le BRGM, ont pour objectif de fournir une meilleure connaissance de ces risques, permettant d’orienter les acteurs vers des solutions adaptées pour s’en prémunir, par des actions concrètes.
La stratégie fédérale mise en place par les États-Unis pour sécuriser l’approvisionnement en minerais critiques de leurs industries
Authors: Sahaguian Alexis , Fernandez Matthieu , Krembel David
Published: July 2020

L’enjeu des matières premières critiques aux États-Unis se structure autour d’un schéma nettement transversal, à la fois géopolitique (rivalité vis-à-vis de la Chine), industriel (rapatrier la production de biens relevant de secteurs stratégiques, sécuriser l’approvisionnement des chaînes logistiques), et idéologique (autonomie des États-Unis au regard d’autres nations, en vertu de la sécurité nationale). La stratégie fédérale se construit néanmoins méthodiquement, de façon pyramidale, chaque ministère apportant sa contribution et moyens d’action sur le fondement du décret présidentiel de décembre 2017, laissant cependant de côté nombre d’enjeux locaux environnementaux et commerciaux multilatéraux, sommés de s’effacer face aux objectifs de l’État fédéral.
Production priorities in dynamic relationships
Authors: Forand Jean Guillaume , Zápal Jan
Published: July 2020

We characterize optimal contracts in a dynamic principal–agent model of joint production in which project opportunities are heterogenous, utility from these projects is nontransferable, and the agent has the option to quit the relationship at any time. To demand the production of projects that benefit her but not the agent, the principal must commit to produce projects that benefit the agent in the future. Production at all stages of the relationship is ordered by projects'
cost‐effectiveness, which is their efficiency in transferring utility between the principal and the agent: cost‐effective demands impose relatively low costs on the agent and cost‐effective compensation imposes relatively low costs on the principal. Over time, optimal contracts become more generous toward the agent by adding commitments to less cost‐effective compensation. In turn, because this new compensation cannot be profitably exchanged against less cost‐effective demands, the principal narrows the scope of her demands.
Costly verification in collective decisions
Authors: Erlanson Albin , Kleiner Andreas
Published: July 2020

We study how a principal should optimally choose between implementing a new policy and maintaining the status quo when information relevant for the decision is privately held by agents. Agents are strategic in revealing their information; the principal cannot use monetary transfers to elicit this information, but can verify an agent's claim at a cost. We characterize the mechanism that maximizes the expected utility of the principal. This mechanism can be implemented as a cardinal voting rule, in which agents can either cast a baseline vote, indicating only whether they are in favor of the new policy, or make specific claims about their type. The principal gives more weight to specific claims and verifies a claim whenever it is decisive.
Insourcing, outsourcing or backsourcing? The case of the Brussels Regional administration
Authors: d’Estmael Jonathan de Wilde , Dermine Elise , Deschacht Nick , Dotti Nicola Francesco , Huegaerts Kelly , Janssens Barbara , Trionfetti Maria Cecilia , Vanroelen Christophe
Published: July 2020

Since the 1980s, there has been a trend for businesses and public administrations to focus on their core activities, outsourcing tasks such as IT, security, catering and cleaning services. However, in recent years, many organisations have been reversing the trend by insourcing, or “backsourcing”, some of these activities. The aim of this article is to study the extent to which activities have been outsourced in the Brussels regional administrations, its impact on workers and organisations involved, and the attitudes of stakeholders towards a possible re-internalisation of low-skilled jobs. Based on a multidisciplinary BSI project for Talent.Brussels, our findings show that decisions about outsourcing and insourcing are complex and multidimensional, and that they should not be based solely on monetary cost considerations.
Klein‐Gordon and Schrödinger equations for a free particle in the rest frame
Authors: Salomatov V. N.
Published: July 2020

A system of two equations is found that has solutions which coincide with the solutions of the Klein‐Gordon equation in the rest frame. This system includes the Schrödinger equation for a free neutral spinless particle. Using the Schrödinger equation as an additional
condition for solving the Klein‐Gordon equation in the rest frame leads to two Helmholtz equations. Helmholtz equations can be solved by specifying a particle model and boundary conditions. One of the Helmholtz equations leads to discreteness of the rest masses of relativistic particles.
Why Newtonian gravity is an electromagnetic wave
Authors: Rotich Nicolus
Published: July 2020

In this brief communication, we have hypothesized that since Newtonian gravity intimately interacts with classical gravitational waves, it must also be perceivable and mathematically expressible as a wave. It has been shown that Newtonian gravity can be represented as an electromagnetic
wave of a particular wavelength  λ  , propagating at the speed of light, c and with a radius of   z =
λ / 2 π   . The waves period is given by T = c/g, and thus acceleration due to gravity is representable as g = cf,
where f is position dependent, and thus unique for all orbiting planetary bodies. On the Earth surface, this value is ≅32.71 nHz.
Formulation of a more realistic quantum equation for rectifying the hidden flaws in Planck's black body equation
Authors: Ghoshal Suniti K.
Published: July 2020

A thorough investigation of the Planck's black-body radiation reveals several potential flaws. It is found that Planck's final formula suffers from a serious dimensional discrepancy. While it relates to the spectral energy density of the black body radiation, the measured experimental
data correspond to the spectral power density. It is shown that Planck's final formula is better written,  P = b ν  where
 P  is power with units      J
/  s     ,   b  is the quantum of energy
with units    J    (numerically equals to Planck's constant,  h
 ), and  ν  is the frequency of the quantum oscillator with units
1  /  s      . It is shown that a simple modification in the Planck's black-body radiation
formula brought about by replacing “  h  ” by “  b  ” in it could make it absolutely free from any flaws and
discrepancies.
A new equation for a mass and its speed
Authors: Wang Chong
Published: July 2020

This work provides that, when an object is accelerated, the substance quantity included in the object should remain a constant with that substance being redistributed within the object. For the same object, a different mass distribution will show a different momentum effect causing
the measured mass to change. Based on this viewpoint, a new mass-speed equation is derived. Analysis shows that the new equation is more compatible with the experimental data than special relativity.
Quantum transition between spaces in a multidimensional Universe and spatial unconnectivity explain free will and solve the measurement problem of quantum mechanics
Authors: Frade José M.
Published: July 2020

Spacetime is deterministic, but the Universe appears to be stochastic. How to reconcile free will with the determinism inherent to the Universe? In this essay, we postulate that free will can only emanate from the existence of multiple additional spatial dimensions constituting the
Universe. As our space displaces through the temporal dimension, we can choose any of the infinite possibilities defined by the additional spatial dimensions, through a process we refer to as quantum transition between spaces. Reality would emerge from the specific materialization of
this quantum transition, resulting in a time series of events. This materialization is based on a fundamental property of any space, independently of its dimensions, which we refer to as spatial unconnectivity. This property implies the inability of the constituents of a particular
space to observe spaces located in other dimensions. Therefore, the unconnectivity between spaces would prevent the simultaneous observation of all possible events at a specific time point, as well as past and future events, resulting in a unique reality. It would be the observers who determine
the temporal trajectory of events, thus providing themselves with free will. In the absence of observers, all possibilities are feasible, thus explaining the quantum properties of elementary particles when they are not directly observed. Our model reconciles quantum mechanics with relativistic
physics and is the easiest way to understand how reality arises in our observable Universe.
An alternative to special relativity: How a flawed experiment and misunderstanding of the fundamental laws of physics diverted physicists from their logical path
Authors: Master-Khodabakhsh Cyrus
Published: July 2020

The purpose of this paper is to show how the result of an erroneous experiment and the lack of understanding of the basic laws of Newtonian mechanics and its application diverted the progress of an important branch of theoretical physics from its true path and led to the creation of
the theory of relativity (SR). Every year, many new papers regarding this theory are published that show its many contradictions and anomalies. This paper shows why Einstein's theory of relativity is theoretically and fundamentally incorrect and why, despite its problems, the theory gives
some empirical predictions. A more logical solution based on Newtonian mechanics and on experiments and observations plus the concept of ether, leading to the same results, is proposed. As an example, mass-energy equivalence  E
≅ m   c   2    is derived to show that Newtonian mechanics
is adequate in the domain of high-speed particles. The derivation in this paper is by a similar technique to what has been previously published by the same author but with a different method of calculation. The paper also shows that SR does not explain, as claimed by Einstein, the null result
of the Michelson and Morley experiment, which is the basis for the theory. It explains why the error in the experiment is hidden and difficult to detect. It also gives more information about the three previously published papers by the same author and endeavors to give a more comprehensive
explanation as to what went wrong in this branch of theoretical physics.

Natural fibers contained in bamboo are beneficial to renewable, biodegradable, abundant availability, and cheap which could be a potential substitute of synthetic materials. Tensile strength of this material is important requirements in various structural application. In this research, fiber fabrication process optimization of three types of local bamboo namely Gombong (Gigantochloapseudoarundinacea), HaurHejo (Bambusatuldoides), and Tali (Gigantochloa apus) was investigated. These fibers were processed by creating a variety of the NaOH concentrations of 4 % and 6 %, immersion times of 1, 2, and 3 hours, and immersion temperatures of 25 °C and 60 °C. The process parameters and its level variations of bamboo fiber fabrication were optimized using Taguchi method. Then the contribution of each process parameter was observed using the analysis of variance (ANOVA). From Taguchi method, the optimal parameter for highest tensile strength was obtained from Tali bamboo, indicated by 4 % NaOH, 2 hours immersion time, and 60 °C immersion temperature. Meanwhile, the ANOVA revealed that the contributions for each parameter are 70 % for bamboo type, 7 % for NaOH concentration, 4 % for immersion time, and 17 % for immersion temperature with error contribution of 2 %. By using these data, it could be concluded that bamboo type selection is a critical parameter to obtain bamboo with high tensile strength. While NaOH concentration, immersion time, and immersion temperature are not critical parameters which gave flexibility in the selection process. FTIR analysis was carried in order to observe chemical bonding in bamboos. The results of FTIR on the bamboo fibers were indicated Tali bamboo has larger lignin levels decreasing than HaurHejo and Gombong, this indicates in higher tensile strength for Tali bamboo fiber.

Mercury pollution through water causes several dangerous diseases. Various efforts have been made to reduce mercury pollution. One of them is by using sorbent. Many ways to improve absorption efficiency, one of which is using magnetic sorbents. This study focused on the effect of grain size and the concentration of Mn0.25Fe2.75O4@SiO2 core-shell on mercury absorption efficiency. The synthesis of Mn0.25Fe2.75O4@SiO2 with 6 and 8 mL of TEOS was carried out through coprecipitation and sol-gel methods. The characterization using XRD, VSM, and FTIR was conducted to determine grain size, properties, and material functional groups proving that SiO2 was successfully covered on the Fe3O4 surface. The percentage of absorption was found by using the AAS instrument. Diffraction data confirmed the presence of Fe3O4 and the amorphous SiO2 phase. According to the Rietveld analysis of all samples demonstrated the particle size of Mn0.25Fe2.75O4 around 11-12 nm. The Mn0.25Fe2.75O4 core had superparamagnetic properties for magnetic separation, and the SiO2 shell could protect the core of being oxidized or dissolved under acid condition. FTIR results showed the sample had a functional group of the main components of Fe-O and SiO2 at a wavenumber of 420-507 cm-1 and 801 cm-1 (stretching) and 1078 cm-1 (bending), respectively. The results of the mercury absorption test indicated that the smaller the grain size and the higher the concentration of TEOS, the percentage of mercury uptake would increase. In addition, the absorption percentage increased with the duration of absorption time given.

Properties of Bacterial Cellulose was depended on the fermentation conditions to produce BC as well as the processing steps for modifying the Bacterial Cellulose microstructure. This study reports on the comparison effect of drying method on Bacterial Cellulose films structure produced from Pineapple Peel Extract. The drying method was done in the oven and freeze-drying. Pellicle as results of fermentation by bacteria was dried in the oven. High-pressure homogenization was applied before the freeze-drying method. BC film structure was observed using scanning electron microscopy and evaluated using X-ray diffraction. The results show that the peak of diffractogram shows crystalline peaks in a relatively similar position, which are at about 14° and 22°. High-pressure homogenizer process before freeze-drying results the structure with higher crystalline compare than oven drying. The index of crystalline and degree of crystalline of BC film in the freeze-drying method were higher than those in the oven with a value of 83% and 86% compared than 81% and 84%, respectively. Drying methods to pellicle in the oven and freeze-drying results in the degree of crystalline of 79% and 71%, respectively. The morphology of the freeze-drying methods contains a more porous structure.

Bacterial cellulose (BC) has applied as a versatile biomaterial in a wide variety of applications, such as biomedical devices, acoustics, electronics, and paper products. The controlling of the procedure could significantly improve the chemical and structure properties of the BC foams. This study aims to compare the features of BC foam that synthesized from BC disintegrated by a high-speed blender (HSB) and high-pressure homogenizer (HPH). The methods are the synthesis of BC using pineapple skin extract, disintegration process using both HSB and HPH following by freeze-drying process and characterization using X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), and FTIR. The results show that freeze-drying to the pellicle did not produce a foam structure of BC. SEM morphology indicates that the disintegration process using HPH produces a better porous BC foam compared than HBS process. XRD analysis shows three peaks associated with the structure of BC, which are at 14.47°, 16.85°, and 22.69°. The crystalline structure of BC foam produced from HPH process has higher than BC foam produced from HBS process. FTIR analysis shows that there is a new peak find out in BC foam after the disintegration process.
