Authors: El Batawi Hisham Yehia , Venkatachalam Thenmozhi , Francis Amirtharaj , Abujabal Rola , Shehadat Saaid Al
Published: April 2020

Background: Helicobacter pylori (H. pylori) is one of the human pathogens proven to be present in the oral cavity due to microaerophilic nature of the dental biofilm. The present study aimed to investigate the presence of H. pylori in cavitated carious lesions of children by polymerase chain reaction (PCR). Study design: Forty-eight children aged between 4 to 7-years attending outpatient Pediatric clinic were enrolled in the study. Caries status and caries severity were assessed using the dmft and ICDAS caries index. Dentine samples were collected for DNA isolation for the detection of H. pylori by PCR. Results: H. pylori was detected among 30% of children with severe caries lesions detected by PCR. Overall, the mean ± SD of the dmft score for H. pylori positive children was higher compared to the negative control. Amongst the H. pylori-positive group, the decayed (mean-dt) number of teeth were significantly higher (p<0.05) than the other group. Moreover, association between severity of caries lesions (codes 5 and codes 6) and presence of H. pylori were significant (p<0.05) when compared negative group. Conclusion: The results demonstrate presence of H. pylori in the cavitated, non-gastric niche of children with severe caries, which possibly could serve as a reservoir for microbial dissemination to other sites of the body.

Authors: Vijayakumar Gopikrishnan , Kamboj Mala , Narwal Anjali , Devi Anju , Singh Virendra
Published: April 2020

Lipomas are common benign neoplasms of oral region which occur scarcely in the parapharyngeal space (PPS). The diversity observed in its histologic presentation classified it into many subtypes among which Spindle Cell Lipoma (SCL) is a rare entity. SCL is an uncommon benign tumor of adipose tissue usually located superficially in the neck, back and shoulder region but its presentation in oral and pharyngeal spaces is very rare. Exhaustive literature search for oral and pharyngeal space pleomorphic SCL till date revealed 45 cases of oral SCL with a mean age distribution of 55 years. Only one reported case of parapharyngeal occurrence of pleomorphic SCL was found. A rare case of pleomorphic variant of SCL in PPS extending into the buccal space is being presented. This case could be the first to report the multiple presentation and the youngest age of occurrence of SCL in PPS.

Published: April 2020

La pudrición blanca producida por Sclerotium cepivorum es la principal limitante del cultivo de ajo en Colombia, causando pérdidas superiores al 50%. La ausencia de semilla de calidad contribuye a su diseminación e infestación en áreas de siembra, siendo la principal estrategia de control la aplicación de fungicidas, por ende, es necesario integrar alternativas de manejo orientadas a su sostenibilidad. Así, el objetivo de este estudio fue determinar bajo condiciones controladas el potencial de control de S. cepivorum con antagonistas microbianos y aceites esenciales. Se determinó en PDA suplementado con cada aceite el efecto sobre el crecimiento del patógeno y para los antagonistas su capacidad para degradar esclerocios. Igualmente, en suelo infestado con esclerocios se determinó el efecto de las aplicaciones de los antagonistas y aceites seleccionados sobre la reducción de incidencia y mortalidad. Los resultados mostraron que la exposición al aceite de eucalipto (10000 ppm) y orégano (200; 250 ppm) inhibió en un 92% el crecimiento del patógeno; en tanto, que los antagonistas colonizaron más del 95% de los esclerocios, provocando su degradación. Mientras que en suelo infestado presentaron un control entre 30 al 70%, siendo Trichoderma asperellum Th034 el que presentó la menor incidencia y mortalidad (21%).
How Does the Budget Deficit Affect Inflation Rate – Evidence from Western Balkans Countries
Authors: Durguti Esat Ali
Published: April 2020

The main purpose of this study is to investigate if determinants that we selected in our analysis have any effects on inflation rate in Western Balkans Countries[1] by using panel data for the period of 2001-2017, in yearly basis in total of 102 observation. The study used quantitative analysis approach and secondary data by applying the multivariate time series, respectively vector error correction model [VECM]. Multivariate time series was applied to investigate whether the budget deficit and other explanatory variable have any significant impact on inflation rate. The results from our analysis shows that three of four determinates that we used are significant on inflation rate. The model summaries statistics for inflation rate which shows that inflation rate has a moderate correlation with explanatory variables that we used in our model, that explanatory variables explain 45.5 percent of dependent variable and we can conclude that a model is a proper and fit. The results suggest that one percent point increase in budget deficit to GDP ratio is associated with about a 9.34 percent point increase in inflation rate.  The overall inference is that the ratios that we selected has a significant influence on the inflation rate in Western Balkans Countries.

Kemampuan Estimator Spline Linear dalam Analisis Komponen Utama
Authors: Arifin Samsul , Islamiyati Anna , Raupong Raupong
Published: April 2020

In the formation of a regression model there is a possibility of a relationship between one predictor variable with other predictor variables known as multicollinearity. In the parametric approach, multicollinearity can be overcome by the principal component analysis method. Principal component analysis (PCA) is a multivariate analysis that transforms the originating variables that are correlated into new variables that are not correlated by reducing a number of these variables so that they have smaller dimensions but can account for most of the diversity of the original variables. In some research data that do not form parametric patterns also allows the occurrence of multicollinearity on the predictor variables. This study examines the ability of spline estimators in the analysis of the main components. The data contained multicollinearity and was applied to diabetes mellitus data by taking cholesterol type factors as predictors. Based on the estimation results, one main component is obtained to explain the diversity of variables in diabetes data with the best linear spline model at one knot point.
Brief: Planning for Information Technology in E&P
Authors: Hunter Les R.
Published: April 2020

This paper provides a framework for planning and investment that integrates the needs of the business and the requirements for information technology (IT). It explains how the application of vision, integrated planning, and portfolio evaluation can encourage a better analysis, thereby ensuring more appropriate investment.

Definitions and Terminology

Table 1 highlights the main topics in this paper. It also outlines checkpoints for the information planning process.

Fig. 1 presents information planning as an integral part of the total business planning process. Business strategies, objectives, and constraints set the overall business environment. All aspects of investment and expenditures should be put in the context of business priorities. The core business investment in wells or facilities and support activities in research, IT, human resources, etc., should be aligned with and prioritized within the broader business objectives. The key deliverables from the integrated planning process are the business plans and the budgets.

IT can be defined as any technology which enables the acquisition, modification, use, and deletion of data or information. In the broadest sense, IT includes non-computer-related data or information like library records that increasingly are available in electronic form. The Information Planning process (exercise) sets the direction and efforts for IT as they relate to business requirements. The total effort from the information planning process is documented in an Information Plan.

The planning process should establish key principles and directions for IT, i.e., set the technical strategies. These principles should define the direction and guidelines for applying IT in the business and how it will migrate or change over the planning cycle.

Alignment of the Business and IT

Initial efforts in the information planning process should identify the business strategies and the enabling IT. This can be a relatively complex task but the final check on the quality of an information plan is whether the correct investment is being made to meet corporate objectives. For example, some new E&P technologies, like 3D petrophysics (interwell logging), will increase the volume of data handled, processed, and stored by several orders of magnitude. Tables 2 and 3 give further examples.
Clean Energy - Preparing Today for Tomorrow's Challenges
Authors: Bowlin Michael R.
Published: April 2020

Published in Oil & Gas Executive Report, Volume 2, Number 2, 1999, pages 18-22.

Imagine a damp morning during Christmas season in London. The city awakes to see streets swirling with a thick, gray mist. But this is no ordinary London fog. As the clouds roll through the streets and seep into the houses, men, women, and children are gasping for breath. Within hours, hospital emergency rooms are crammed with people complaining of stinging lungs. When the fog finally lifts 5 days later, thousands are dead.

It sounds incredible doesn't it? A dooms-day scenario dreamt up by a Hollywood writer, and something that - we hope - never could happen. But, it already did, in 1952. In fact, that scene was simply the worst of the so-called "killer fogs" or "pea-soupers" that repeatedly struck London, Liverpool, and other areas of England and Wales after World War II. They were caused when warm masses of air trapped smoke and fumes, primarily generated by coal heating. The1952 fog, which killed more than 4,000 people and contributed to the subsequent deaths of another 8,000, ultimately prompted the British Parliament to pass the Clean Air Act in 1956.

If the killer fog of the winter of 1952 was an environmental "wake-up" call for Britain and the West, perhaps the burning of the Indonesian rain forests in1997 and 1998 will prove to be the alarm that awakens the developing world to the importance of environmental conservation. Literally hundreds of blazes across the sprawling nation of islands contributed to a choking smoke haze that blanketed parts of Southeast Asia. The health and safety of millions of people in Indonesia, Singapore, Malaysia, Brunei, southern Thailand, and parts of the Philippines were threatened by the consequences of slash-and-burn fires aimed at clearing land.

That disaster put the dilemma of the developing world into stark relief. If you have been to Beijing, Bangkok, or Mexico City recently, you know how bad air quality can get. Visibility is so poor that some days it's hard to see across the street. More importantly, public health is endangered. Like Londoners in the early 1950's, thousands of people today are dying prematurely, and the health and productivity of countless others are impaired.

Now imagine these cities with more automobiles and with each person using more and more energy. This is precisely what will happen as a result of rising income levels and urbanization. The world now has almost 6 billion people. Two billion more will be added by 2025. Primary energy usage is likely to grow by more than 50% by that time as the children of the billions of people now without commercial energy services are added to electricity grids and acquire automobiles, trucks, or motorcycles.
Inhibition of neuroinflammatory nitric oxide signalling supresses protein glycation and recovers neuronal dysfunction in prion disease
Authors: Bourgognon Julie-Myrtille , Spiers Jereme G. , Robinson Sue , Scheiblich Hannah , Ortori Catharine , Bradley Sophie J. , Tobin Andrew B. , Steinert Joern
Published: April 2020

Background: Several neurodegenerative diseases associated with protein misfolding (Alzheimer’s, Parkinson’s disease) exhibit oxidative and nitrergic stress following initiation of neuroinflammatory pathways. Associated nitric oxide (NO)-mediated post-translational modifications impact upon protein functions that can exacerbate pathology. Non-enzymatic and irreversible glycation signalling has been implicated as an underlying pathway that promotes protein misfolding, but the direct interactions between both pathways are poorly understood. Methods: Here we investigated the potential therapeutic effects of supressing neurotoxic NO signalling during early progression of prion disease. Tg37 mice aged 3-4 weeks were inoculated by intracerebral injection with either 1% brain homogenate of Rocky Mountain Laboratory (RML) scrapie prion protein or control normal brain homogenate (NBH). Hippocampal gene and protein expression levels of oxidative and nitrergic stress markers were analysed and electrophysiological characterisations of pyramidal neurons were performed in 6-10 weeks old RML and NBH mice. Mice were injected with a NO synthase (NOS) inhibitor and the time course of disease markers was compared to controls. Electrophysiology, immunoblotting and immunocytochemistry studies were performed to identify the effects of NOS inhibition on neurophysiology, glycation, prion protein misfolding and cell death. Statistical analyses employed two-tailed unpaired Student’s t-test, one-way or two-way ANOVA as required and data were considered significant with P<0.05.Results: Increased neuroinflammatory signalling was observed in mice between 6 and 10 weeks post inoculation (w.p.i.) with scrapie prion protein which was characterised by enhanced nitrergic stress and associated with a decline in hippocampal neuronal function by 9 w.p.i.. Daily in vivo administration of the NOS inhibitor L-NAME between 6 and 9 w.p.i. at 20 mg/kg abolished the functional degeneration of hippocampal neurons in prion mice. We further found that this intervention in diseased mice ameliorated 3-nitrotyrosination of triose-phosphate isomerase, an enzyme involved in the formation of disease-associated glycation signalling. Furthermore, L-NAME application reduced the expression of the receptor for advanced glycation end products and the accumulation of hippocampal prion misfolding. Conclusions: Our data suggest that alleviating nitrergic stress during early phases of neurodegeneration reduces neurotoxic post-translational NO signalling and glycation-assisted prion misfolding in the hippocampus, a mechanism which might be applicable to other protein misfolding neurodegenerative conditions.

Published: April 2020

Background

The objective of this study was to assess the effects of diet on bacterial species in the solid fraction of the ruminal content using the gene sequences of the conserved 16S rDNA region steers fed one of the following diets: canola (C), cottonseed (A), sunflower (G), soybean (SO), corn silage (S) and control diet (PD). Canola, cottonseed, sunflower and soybean were fed as whole seeds. Six crossbred steers (Body weight = 416.33 ± 93.30 kg; mean ± SD), castrated male, and fitted with ruminal cannula were used. The experimental design was a 6 × 6 Latin square design.

Results

Cellulolytic bacteria were predominant for all diets, with 47.75% of Operational Taxonomic Units (OTU) in animals fed the cottonseed diet. Amylolytic bacteria were identified for all diets, representing 62.51% OTU in animals consuming the sunflower diet. Proteolytic bacteria were identified for all diets, corresponding to 65.96% OUT in animals fed the sunflower diet. Lactic bacteria were identified for all diets. Megasphaera elsdenii bacterium was identified for all diets, with a greater diversity of this bacterium in steers fed the control diet. This bacterium may reduce the availability of hydrogen in the rumen due to propionate production and lactate utilization.

Conclusion

Oilseed in the diet showed a similarity of bacteria species with 47.5% of changing of the ruminal flora.
Silencing of Tenascin-C inhibits hypoxia reoxygenation injury of cardiomyocyte through TLR4和NF-κB pathway
Authors: Ge Zhiru , Zhang Chenjun , Lin Jie , Pan Hong , Lin Zijun , Zhang Wei
Published: April 2020

Background: Myocardial infarction (MI) is one of the leading causes of morbidity and mortality worldwide, and its main pathophysiological mechanism is myocardial ischemia/reperfusion (I/R) injury. TNC is an extracellular matrix glycoprotein, and high TNC expression was associated with MI and ventricular remodeling. The present study aimed to investigate the effect and the underlying mechanisms of TNC on myocardial I/R injury.Methods: Cardiomyocyte H9c2 cells was used to establish an in vitro hypoxia/reoxygenation (H/R) model, which were under hypoxia for 4 h and reoxygenation for 12 h. TNC was silenced by small interfering RNA (siRNA) in H9c2 cells.Results: TNC mRNA and protein expressions were increased by H/R. TNC knockdown by siRNA improved the cell viability in H/R-stimulated H9c2 cells. TNC knockdown reversed the H/R-induced increase in the apoptosis, as evidenced by reduced TUNEL+ cells and caspase-3 activity, and inhibited oxidative stress and inflammatory cytokine production. TNC silencing inhibits TLR4 mRNA and protein expressions and NF-kappa B signals, as evidenced by reduced nuclear NF-κB p65 and increased cytoplasmic I-κBα in H/R-stimulated H9c2 cells. All these cardioprotection against H/R by siTNC was reversed by TLR4 overexpression.Conclusions: TNC silencing prevents H/R-induced injury by inhibiting apoptosis and oxidative stress by inhibition of TLR4-NF-κB pathway.
Forecasting the impact of the containment measures for COVID-19 in France, Italy, and Spain
Authors: Almohammed Omar A , Alhifany Abdullah A. , Al-Ruthia Yazed S.
Published: April 2020

Background: The Coronavirus disease of 2019 (COVID-19) is now a major challenge for healthcare systems in many countries, including some of the G20 countries like China, Italy and France. The purpose of this paper was to estimate how this disease could impact Italy, Spain and France, in comparison to China, based on the timing of their first response to the epidemic.Methods: The study visually estimated when will the suppression strategies implemented in Italy, Spain and France would change the direction of the daily new infections curve. The study utilizes the publicly available data from the WHO website. The curve representing the response strategy from China was used as a visual reference in this case, assuming that the virus is impacting all populations in the same way, transmitted in similar rate, and the time needed from the implementation of the suppression strategies to the appearance of its impact would be identical in all countries. Then, the total number of cases and deaths will be estimated from the produced curve, based on the current death rate among all infected people in each countryResult: The response in the three countries was not as fast as it was in China. Based on the cumulative number of cases at the response time, France was the fastest responder to the epidemic; therefore, we expect it will be the least impacted among three countries with about 97,523 cases and 4,876 deaths. Followed by Spain with approximately 153,013 cases and 14,536 deaths, then Italy with 162,885 cases and 20,034 deaths. The peak date for the new confirmed cases was expected to be around April 2nd for Italy and Spain, and April 6th for France. Then, the new daily cases should be declining to around Zero by the end of April or the beginning of May.Conclusion: Italy, followed by Spain, will be the most impacted countries in the European Union. Therefore, the support for Italy and Spain at this time is very needed, especially with medically trained personnel.
Adaptive Mobile Health Intervention for Adolescents with Asthma: Iterative User-Centered Development
Authors: Fedele David A , Cushing Christopher C , Koskela-Staples Natalie , Patton Susana R , McQuaid Elizabeth L , Smyth Joshua M , Prabhakaran Sreekala , Gierer Selina , Nezu Arthur M
Published: April 2020

Background

Adolescents diagnosed with persistent asthma commonly take less than 50% of their prescribed inhaled corticosteroids (ICS), placing them at risk for asthma-related morbidity. Adolescents’ difficulties with adherence occur in the context of normative developmental changes (eg, increased responsibility for disease management) and rely upon still developing self-regulation and problem-solving skills that are integral for asthma self-management. We developed an adaptive mobile health system, Responsive Asthma Care for Teens (ReACT), that facilitates self-regulation and problem-solving skills during times when adolescents’ objectively measured ICS adherence data indicate suboptimal rates of medication use.

Objective

The current paper describes our user-centered and evidence-based design process in developing ReACT. We explain how we leveraged a combination of individual interviews, national crowdsourced feedback, and an advisory board comprised of target users to develop the intervention content.

Methods

We developed ReACT over a 15-month period using one-on-one interviews with target ReACT users (n=20), national crowdsourcing (n=257), and an advisory board (n=4) to refine content. Participants included 13-17–year-olds with asthma and their caregivers. A total of 280 adolescents and their caregivers participated in at least one stage of ReACT development.

Results

Consistent with self-regulation theory, adolescents identified a variety of salient intrapersonal (eg, forgetfulness, mood) and external (eg, changes in routine) barriers to ICS use during individual interviews. Adolescents viewed the majority of ReACT intervention content (514/555 messages, 93%) favorably during the crowdsourcing phase, and the advisory board helped to refine the content that did not receive favorable feedback during crowdsourcing. Additionally, the advisory board provided suggestions for improving additional components of ReACT (eg, videos, message flow).

Conclusions

ReACT involved stakeholders via qualitative approaches and crowdsourcing throughout the creation and refinement of intervention content. The feedback we received from participants largely supported ReACT’s emphasis on providing adaptive and personalized intervention content to facilitate self-regulation and problem-solving skills, and the research team successfully completed the recommended refinements to the intervention content during the iterative development process.
TUNING PD AND PID CONTROLLERS VIA THE LAMBERT W FUNCTION FOR DOUBLE INTEGRATOR PLUS DEAD TIME PROCESSES
Authors: Gerov Radmila , Jovanović Zoran
Published: April 2020

The paper explores the Proportional-derivative controller for a double integrator plus dead time processes, which is a challenging control problem, that is designed based on the existing Proportional-integrative controller for integrator plus dead time processes. The PD controller is extended with an integral action and an ideal PID controller is received. The parameters of both controllers are received by using the pole placement technique, whereby the transcendent characteristics equation of the closed loop system is solved by using the Lambert W function. The paper also examines the influence of the desired poles of the system with a closed feedback as well as the influence of the disturbance and the change of the DIPTD processes parameters onto the received control system performances. The results received by simulation, and the quantitative indicators, show that the proposed control system has better performances in comparison to the control systems obtained by other methods in literature.

Território, desenvolvimento e sustentabilidade – reflexões a partir da teoria de Karl Polanyi
Authors: Besen Fabíola Graciele , Plein Clério , Andrade Marcos , Junior Valdir Serafim
Published: April 2020

A partir do momento em que o mercado passou a ser autorregulável, ele aniquilou as instituições sociais, o homem e a natureza, pois o trabalho e a terra passaram a ser oferecidos em mercados próprios, semelhantes a mercadorias, conforme aponta Polanyi (2012) em sua obra “A subsistência do homem”. Assim, o sistema econômico passou a ser o suporte para as relações sociais, enquanto exatamente o inverso deveria prevalecer, segundo o entender de Polanyi (2012). Dessa forma, os efeitos do mercado aniquilam o homem, as instituições sociais e a natureza. A crise ambiental, frente a esta perspectiva em curso, tem contribuído para questionar a racionalidade e os paradigmas teóricos, que, impulsionaram e legitimaram o crescimento econômico ainda vigente. De acordo com Polanyi (2000, p. 214) “o trabalho é parte da vida, a terra continua sendo parte da natureza, a vida e a natureza formam um todo articulado”. Assim, o desenvolvimento econômico precisa ser compreendido a partir da cultura e das instituições. Nesse sentido, esse trabalho busca desenvolver uma discussão interdisciplinar a partir dos conceitos presentes na teoria de Karl Polanyi para apresentar alguns processos relacionados ao desenvolvimento, território e sustentabilidade.
The prospect of dual-use products production in the CSTO and EAEU countries
Authors: Yampolskaya Diana O.
Published: April 2020

The ongoing sanctions and growing tension in the field of global trade leads to the necessity of looking for various economic relations schemes between the countries of the Eurasian Economic Union (EAEU) and the Collective Security Treaty Organizations (CSTO). All participating countries need to strengthen ties and find ways to produce dual-use goods to more successfully confront global challenges, both in the economic, political and military spheres. The problem of cooperation can be solved by focusing on the strengths of the economies of the CSTO countries. Identification of production opportunities for goods and dual-use services would aim at the direction of cooperation in of various countries. This article is devoted to studying the production capabilities of Armenia, Belarus, Kazakhstan, Tajikistan and Kyrgyzstan for the production of dual-use products under import substitution programs. Studies have shown that almost all countries of the economic union possess numerous natural resources that are used in the production of innovative products. But there are significant problems in the development of technologies for the production of dual-use goods and, unfortunately, the Russian Federation cannot fully rely on the potential of the CSTO countries in this matter.

Do we need revision of the key geopolitical paradigms?
Authors: Vukovic Nebojsa
Published: April 2020

The foundation of and justification for the revision of an very important
conceptual paradigm that, for decades past, have had a reputation for being
the basic premise in the history of geopolitics as a (sub)discipline of
(political) geographyare explored in the paper. It is classical
Mackinder-Spykman?s dichotomy of the Eurasian mainland into the heartland
and the rimland. Since humankind is a witness to undisputed climatic changes
and global warming, which also manifests very intensively through the
process of the melting of Arctic ice, the author of the paper explores
whether the current retreating of ice from the Arctic annuls or at least
relativizes the foundation of Halford John Mackinder?s concept of the
heartland as a Eurasian ?strategic fortress? of its own kind, which inter
alia owes the status it has to the existence of the white barrier (eternal
ice) in the extreme north of the planet Earth. This dilemma gives rise to
the next that is related to the familiar thesis of the American
geopolitician Nicholas John Spykman of the crucial importance of the
Eurasian rimland in the global competition of the great powers. If the
Arctic Ocean stays without ice for the largest part of the yearone day,
should in that case the northern mainland of the Russian Federation also be
perceived as the rimland in the meaning as devised by Spykman? The author
explores what the scope, content and meaning of the notions of heartland and
rimland could be at all if the global warming trends present so far
continued. So, the paper questions and critically perceives the two maybe
most important (hypo)theses in the history of geopolitics, whose authors
were Mackinder and Spykman, in the context of far-reaching climatic changes.
Apart from this, the author of the paper proves/refutes the justification
for the (hypo)thesis of the division of geopolitics into the so-called
classical (i.e. ice) and post-ice (i.e. that which becomes relevant after a
partial or maybe even full retreat of ice from the Arctic). At the very end
of the paper, again in the context of the mentioned changes, the author
points to the ever-increasing significance that is being assigned to the
?population? factor in geopolitics. Namely, even if climatic changes and the
warming process were developing according to the scenario which is the best
for man, we may yet pose a question of the possibility of the exploitation
of all the potentials of the Arctic Basin in a situation when, with some
rare exceptions, the northern hemisphere?s population does not increase,
i.e. when it stagnates or even falls in numbers.
Geopolitical thought in the Apennine peninsula: Teachers and students
Authors: Jankovic Slobodan
Published: April 2020

Italy is one of the countries that developed a particular geopolitical
thought in the first half of the 20th century, and it was abruptly ended
with the fall of the fascist regime in Rome. The revival of geopolitics
opened the question of the characteristics of this discipline in
contemporary Italy. The author asks two research questions: 1) whether there
is continuity with the old school, and if yes, in what measure? 2) What were
the characteristics of Italian geopolitics in its formative period until
1943? The text has four chapters. The introductory part explains the context
in which geopolitical thought in the Apennines arises in interaction with
scientific and social-political changes in Europe and globally. The second
part follows the roots, evolution, and conclusion of the geopolitical
thought until 1943. The third chapter has two parts in which the author
depicts the context in which geopolitics emerges again. In this part, the
main authors, reviews and web sites are presented and analysed. In the
concluding part of the text, the author defines three main lines of
geopolitical thought in Italy. He clearly distinguishes between those who
have a clear line of continuity with Massi and Roletto - the old school -
and those who have adopted different frameworks.
From a critique to self-evolving (inter)discipline: Critical geopolitics vs. popular geopolitics
Authors: Zorko Marta , Srsen Dario
Published: April 2020

The paper shows the development of critical geopolitics from its
conceptualisation by O Tuathail, Dalby and Routledge at the end of the last
century up to its critics and development of phenomena that influenced the
self-evolution of discipline. The first goal of this research is the
analysis of the main thesis from the abovementioned authors in order to test
them on contemporary examples. The second goal is consisted of the
contemporary phenomena analysis, from the media critique to a wider societal
critique, as well as their influence on the self-evolution of the
discipline, especially in the area of popular geopolitics. This review
streams towards the state of the art analysis, defining and positioning this
(inter)discipline in frames of old/new geopolitics, international relations,
and human geography. The main thesis is that contemporary phenomena (as a
cause) narrowed down the focus of research areas in some scientific fields,
while in others it made unavoidable to skip interdisciplinary perspective
both in theoretical as well as in methodological sense. The critics of
classical geopolitics developed three directions for research: as a part of
critical geopolitics as self-contained discipline and numerous
subdisciplines or even disciplines (e.g., popular geopolitics); as critiques
of newly developed neoclassical theories and schools in international
relations; and as interdisciplinary attempts that highlights research on
contemporary phenomena and criticise all so far developed methods and tools
as nonadequate for research in such a complex world of the present
challenges.
An innovated paradigm of geopolitical phenomena quantification: Interpretations, methods, and data sources
Authors: Stekic Nenad
Published: April 2020

Research of geopolitical phenomena and processes is being characterized by
the scholarly tendency to opt for qualitative research strategies with the
complementary use of descriptive statistical methods. The states? behaviour
within the international system in the manner of conducting their
geopolitical code has not been the subject of significant quantitative
interest in academic thought over the last decades of the 20th century. A
massive emergence of datasets as instruments of quantification, which index
geopolitical phenomena, has been accompanied by the rise of quantitative
geopolitical studies at the end of the last century. This paper aims to
present the current situation in academic discourse related to the review of
the most used quantitative methods in the study of geopolitical phenomena
and to analyze the interpretation of the findings of such research. The key
advantage of quantifying geopolitical phenomena is also their biggest
problem - the data sources diversity used to quantify different phenomena
results in many inconsistencies, ranging from research practices, research
methods and techniques to the interpretation of statistical findings. Based
on the review of existing literature regarding the shatterbelt concept and
insights into some of the individual quantitative research, the author
preliminary defines three research stages in the quantification of
geopolitics and concludes the quantitative approach is underdeveloped in the
study of this scientific discipline. In addition, existing data collection
and collection methods and techniques are not sufficiently systematic or
uniform, but provide a fruitful basis for considering long-term processes
taking place in a particular geographical area.
The geopoliticAl context of energy security
Authors: Prorokovic Dusan
Published: April 2020

Geopolitical conceptions also have an ?energy dimension?, just as energy
security can and must be considered in the context of geopolitics. The twenty-first
century remains a century of fossil fuel use. It should be expected that the share of coal
in the total energy balance will decline, but also that the share of natural gas use will
increase. Political decisions and international relations as a whole will be correlated
with the geographical distribution of oil and natural gas sources and routes of the
strategic pipelines. This paper discusses this issue in five chapters. The first is
introductory, explaining the definitions of energy security and geopolitics. The second
chapter is devoted to explaining the importance of energy issues for political relations,
and the third presents the geographical distribution of energy sources and reserves.
The geopolitics of energy security with some examples from contemporary international
relations is described in Chapter Four, while the last part of the paper deals with
concluding considerations.
Perancangan Pengendali Hybrid PID Gain Schedulling dan Sliding Mode Control Untuk Pengendalian Level
Authors: Mursyitah Dian
Published: April 2020

Pengukuran tinggi permukaan cairan (level) dalam bejana, tabung dan tangki sering kali dijumpai di dunia industri. Permasalahan yang terjadi pada pengendalian level adalah suplai laju aliran yang tidak stabil   mengakibatkan respon waktu pencapaian level yang diinginkan menjadi lambat, terlebih lagi saat perubahan setpoint level. Permasalah ini diselesaikan dengan perancangan pengendali PID yang dikombinasikan dengan Gain Schedulling. Kombinasi PID dan Gain Schedulling mampu menyelesaikan persoalan pencapaian setpoint. Namun, pencapaian setpoint memerlukan waktu yang lama. Untuk menyelesaikan permasalahan tersebut, dipilih pengendali sliding mode control (SMC) untuk menangani persoalan respon waktu. Hasil simulasi menunjukkan, bahwa kombinasi pengendali hybrid PID gain scheduling dan sliding mode control mampu mencapai set point dengan waktu yang cepat. Pengujian tersebut didapat hasil dari tiga perubahan setpoint level yaitu 25%, 50%, 75%, dan 100%. Dengan nilai rise time yang diperoleh berurutan yaitu  225,1138 detik, 439,5982 detik, 413,3095 dan 537,1012 detik dari total waktu simulasi sebesar 2500 detik

Published: April 2020

Kelurahan Tangkerang Barat merupakan salah satu kelurahan yang ada di Kecamatan Marpoyan Damai Kota Pekanbaru. Masyarakat Kelurahan Tangkerang Barat tepatnya di RW 004 RT 006 memiliki upaya untuk mengelola sampah rumah tangga dengan membentuk program Rumah Kelola Sampah. RKS ini dilakukan edukasi percobaan di 10 rumah warga. Setelah dilakukan edukasi pecobaan, hanya 3 rumah warga yang bersedia mengikuti program RKS mengolah pupuk organik cair. Hal ini dikarenakan dalam pengolahan pupuk organik cair berbau sangat busuk yang disebabkan proses pembuatan pupuk tersebut hanya diletakkan didalam tong komposter. Penelitian ini bertujuan untuk mengetahui proses pembuatan pupuk organik cair, mengetahui nilai unsur hara Nitrogen (N), Fospor (P) dan Kalium (K), menghitung Harga Pokok Produksi dan Break Event Point pada pupuk organik cair. Metode yang digunakan pada penelitian ini adalah metode Variable  Costing untuk menghitung HPP dan metode Rancangan Rangkap Acak untuk menetukan perlakuan pada pupuk cair. Hasil penelitian menunjukkan bahwa proses pembuatan pupuk organik cair meliputi proses persiapan bahan, pemilihan, pembersihan, penghalusan, penyaringan, pencampuran dan proses fermentasi. Dari hasil uji laboratorium menunjukkan bahwa perlakuan pupuk organik cair sampel C dengan larutan EM4 sebanyak 20 ml memiliki hasil yang baik dengan nilai Nitrogen 0,1585%, Fospor 0,1439% dan Kalium 0,0294%. Perhitungan harga pokok produksi pupuk organik cair sebesar Rp 11.000/Liter dan Break Event Point yaitu sebanyak 9 Liter dan dalam rupiah sebesar Rp 99.382,92.

Studi kasus ini mendeskripsikan aktivitas pada suatu terminal petikemas yang memiliki rata-rata dwelling time selama 8 hari. Hal ini memperlambat aktivitas pada terminal petikemas dan merugikan berbagai pihak meliputi pemilik barang dan pihak terminal peti kemas. Tujuan penelitian ini adalah untuk membuat seknariao perbaikan dalam mengurangi aktivitas dwelling time di terminal petikemas. Penelitian ini menggunakan pendekatan discrete event simulation untuk melakukan perbaikan aktivitas pembongkaran dengan membuat beberapa skenario perbaikan. Hasil yang diperoleh bahwa skenario pertama dengan penambahan 1 unit reach steker dan skenario kedua melakukan penanambahkan 1 unit reach steker dan 1 unit top loader. Dengan menggunakan Software Arena, diperoleh output truk pada skenario satu adalah 38 truk dan pada skenario dua adalah 37 truk. Dengan demikian, skenario satu lebih tepat untuk menjadi skenario terpilih. Lebih lanjut, rata–rata total biaya storage setiap bulan yang dibayar costumer adalah Rp 1.528.400 untuk container 20” dan Rp 3.437.950 untuk container 40”. Implikasi pada penelitian ini dapat meberikan usulan perbaikan pada aktivitas pembongkaran di petikemas. Penelitian selanjutnya di harapkan dapat menambah jumlah skenario perbaikan untuk pengurangan dwelling time.

La apoteosis del plural
Authors: Innerarity Daniel
Published: April 2020

RESUMENEn este escrito se describe la filosofía del plural de Blumenberg, como un caso señalado de ese pluralismo de significaciones que se ha convertido en la signatura de la filosofía posmoderna. A mi juicio, ese pluralismo corre el peligro de la indiferencia, que atenaza el curso temporal de la vida humana; frente a ella sugiero la posibilidad y el sentido vital de las preferencias razonables.
