Development of Fire and Explosion Risk Assessment on Coal Reclaim Tunnel Using Monte Carlo Simulation and Risk Matrix Method
Authors: Widodo Nuhindro Priagung , Permadi Dimas Agung , Ihsan Ahmad , Kusuma Ginting Jalu
Published: July 2021

The comprehensive fire and explosion risk assessment has been studied
for Coal Reclaim Tunnel (CRT) facility by applying the Monte Carlo
simulation method. In this research, the fire and explosion risk of two
existing CRT, namely model A and model B, have been assessed. A set of
30 data for each factor has been used to define the statistical
distribution model, sourced from historical data, field measurement, and
laboratory experiments. Based on the simulation, CRT model A has a 100%
extreme risk group, while model B has two risk groups, high risk=81.73%
and moderate risk=18.27%, classified as a not acceptable risk. Several
preventive actions were set to reduce the probability and severity level
as low as reasonably possible, especially for the controllable factors.
Furthermore, the probability and severity levels were re-adjusted by the
Monte Carlo simulation. The result shows that both the CRT model have
been grouped into a 100% moderate-risk group. For optimal prevention
against explosion risk, a sensitivity analysis has been carried out to
find the most influential factors for the fire and explosion risk in
CRT. Through this research, a method for risk matrix assessment related
to the fire and explosion in the CRT facility has been developed.

Diagnosis, Monitoring, and Management of Pyruvate Kinase Deficiency in Children
Authors: Johnson Shaniqua , Grace Rachael , Despotovic Jenny
Published: July 2021

Pyruvate kinase (PK) deficiency is an important cause of hereditary
non-spherocytic hemolytic anemia caused by a defect in the glycolytic
pathway in red blood cells. PK deficient erythrocytes have impaired ATP
production and resultant difficulty maintaining normal cell integrity
and function, leading to mild to severe anemia due to increased
extravascular hemolysis and splenic destruction. Sequelae of chronic
hemolysis can result in severe and occasionally life-threatening
complications such as hepatobiliary disease, iron overload, bone and
cardiopulmonary disease, as well as often markedly impaired quality of
life. While the mainstay of management of PK deficiency involves
supportive care, comprehensive screening recommendations and disease
modifying therapies in development are likely to significantly improve
the management of patients. Here, we provide a case-based comprehensive
review of the diagnostic evaluation, complications, monitoring
recommendations and management of PK deficiency in children.
The Interface is a Tunable Dimension in Electricity-Driven Organic Synthesis
Authors: Wuttig Anna , Toste Dean
Published: July 2021

Predictive control over the selectivity outcome of an organic synthetic
method is an essential hallmark of reaction success. Electricity-driven
synthesis offers a reemerging approach to facilitate the design of
reaction sequences towards increased molecular complexity. In addition
to the desirable sustainability features of electroorganic processes,
the inherent interfacial nature of electrochemical systems present
unique opportunities to tune reaction selectivity. To illustrate this
feature, we outline examples of mechanism-guided interfacial control
over CO2 electroreduction selectivity, a well-studied and instructive
electrochemical process with multiple reduction products that are
thermodynamically accessible. These studies reveal how controlled proton
delivery to the electrode surface and substrate electroadsorption with
the electrode dictate reaction selectivity. We describe and compare
simple, yet salient, examples from the electroorganic literature, where
we postulate that similar effects predominate the observed reactivity.
This perspective highlights how the interface serves as a tunable
dimension in electrochemical processes, delineating unique tools to
study, manipulate, and achieve reaction selectivity in
electricity-driven organic synthesis.
Inducible responses to antagonistic predation risks are not in a dilemma: Evidences from multi-traits and transcriptome of Ceriodaphnia
Authors: Gu Lei , Qin Shanshan , Sun Yunfei , Huang Jing , Akbar Siddiq , Zhang Lu , Yang Zhou
Published: July 2021

Inducible defenses of prey are evolved under diverse and variable
predation risks. In the co-evolution of prey and multiple predators with
antagonistic selection pressures, whether inducible defense responses of
prey will fall into a dilemma and its underlying mechanism are still
unclear. Based on the antagonistic predation pressure from invertebrate
predator Chaoborus larvae and vertebrate predator fish, we studied
multi-traits and transcriptome of the freshwater crustacean Ceriodaphnia
cornuta under multiple predation risks. Our results showed that
Chaoborus larvae predation risks altered the expression of genes
encoding cuticle protein and changed the biosynthesis of steroid
hormone, cutin, suberine, and wax, promoting Ceriodaphnia to express
horns and grow larger at a late development stage, whereas fish
predation risks mainly triggered responses in genes encoding ribosome
and pathways of unsaturated fatty acids biosynthesis, cysteine and
methionine metabolism, resulting in a smaller individual size and
earlier reproduction. The inducible responses on transcription and
individual traits both revealed that predator unique responses are
dominant and the antagonistic responses are the least. Besides, Pearson
correlations between different predator unique responses are extremely
weak. Furthermore, the unique individual traits triggered by different
predators can be expressed simultaneously. These results indicated that
Ceriodaphnia can avoid the dilemma by performing predator unique
responses and diverse inducible responses are favored in the
co-evolution of zooplankton and multiple predators.

Published: July 2021

Introduction/Objective. This study aimed to translate the original disease-specific Malocclusion Impact Questionnaire (MIQ) into Serbian and validate the new version in the cohort of young Serbian orthodontic patients. Methods. At the university clinic, 154 patients filled out the MIQ in Serbian before the start of the orthodontic treatment; 112 participants filled out the same questionnaire four weeks later. The Index of Orthodontic Treatment Need ? Dental Health Component (IOTN-DHC) and Peer Assessment Rating (PAR) pretreatment scores were recorded. Descriptive statistic, Cronbach?s ?, Spearman?s ?, and exploratory factor analysis, followed by parallel analysis for factor reduction, were calculated and analyzed. Results. One hundred forty-eight patients with no missing responses (51 male, 97 female), of the average age of 13.3 ? 2 years, had MIQ total scores mean of 10.14 ? 7.451. Internal reliability (? = 0.913), external reliability (? = 0.906; p = 0.000), construct validity tested by MIQ total scores and two global question scores? correlations (? = 0.682; p = 0.000 and ? = 0.366; p = 0.000), as well as clinical validity tested by correlations of MIQ total scores with PAR pretreatment scores (? = 0.181; p < 0.05), and IOTN-DHC scores (? = 0.192; p < 0.05) were positive and statistically significant. One item factor was extracted and it explained a large part of the cumulative variance. Conclusion. Reliability and validity of the translated and cross-culturally adapted MIQ in Serbian is satisfactory. It could be used for malocclusion-related quality of life assessments in young Serbian orthodontic patients.
Design and development of industrial IoT-based system for behavior profiling of non-linear dynamic production systems based on energy flow theory
Authors: Medojevic Milovan , Tejic Branislav , Medojevic Milana , Kljajic Miroslav
Published: July 2021

In this paper, a solution effective energy consumption monitoring of fast-response energy systems in industrial environments was proposed, designed, and developed. Moreover, in this research, production systems are characterized as non-linear dynamic systems, with the hypothesis that the identification and introduction of non-linear members (variables) can have a significant impact on improving system performance by providing clear insight and realistic representation of system behavior due to a series of non-linear activities that stimulate the system state changes, which can be spotted through the manner and intensity of energy use in the observed system. The research is oriented towards achieving favorable conditions to deploy dynamic energy management systems by means of the IoT and big data, as highly prominent concepts of Industry 4.0 technologies into scientifically-driven industrial practice. The motivation behind this is driven by the transition that this highly digital modern age brought upon us, in which energy management systems could be treated as a continual, dynamic process instead of remaining characterized as static with periodical system audits. In addition, a segmented system architecture of the proposed solution was described in detail, while initial experimental results justified the given hypothesis. The generated results indicated that the process of energy consumption quantification, not only ensures reliable, accurate, and real-time information but opens the door towards system behavior profiling, predictive maintenance, event forensics, data-driven prognostics, etc. Lastly, the points of future investigations were indicated as well.

Published: July 2021

This article reports on using Kalina cycle for waste heat recovery from a cement plant. Two design alternatives have been investigated using separate and combined waste heat recovery from the kiln, cooler, and preheater. Measurements and analysis have been performed to determine the waste heat from different stages of the cement manufacturing lines. The annual heat losses from the kiln surface, preheater, and the cooler are estimated as 79.23 GWh, 44.32 GWh, and 43.6 GWh at average temperatures of about 314?, 315?, and 254?, respectively. Analysis and optimization of using Kalina cycle for waste heat recovery from the kiln shell, cooler and preheater to produce electricity have been carried out using ASPEN software. Parametric study has been carried out to determine the design parameters for Kalina cycle including turbine inlet pressure, mass-flow rate, and NH3-H2O concentration. The value of net power output using combined waste heat recovery is about 7.35 MW as compared to 6.86 using separate waste heat recovery design with a total cost saving of about 23%.
Three-component diagnostics of swirling flow in the model of an improved four-vortex furnace
Authors: Alekseenko Sergey , Anufriev Igor , Shadrin Evgeniy
Published: July 2021

The spatial structure of a swirling turbulent flow has been investigated based on the three-component laser Doppler anemometry method in an isothermal laboratory model of a four-vortex furnace. The structure of the vortex cores of the flow with the shape of a deformed vertical elliptical cylinder is visualized using the ?minimum total pressure? criterion. The spectrum of velocity pulsations indicates the absence of unsteady periodic vortex structures, which means the occurrence of a stable vortex flow in the volume of the combustion chamber.
Determination of the drag coefficient of lattice structures under wind load using porous media approach
Authors: Pezo Milada , Mirkov Nikola , Bakic Vukman
Published: July 2021

The power transmitters, guyed masts and other lattice structures are exposed to wind action. The aerodynamic forces acting on tall tower constructions have crucial importance on the stability of the structure. The lattice structure drag coefficient determination is the subject of the international standards ESDU 81027 and 81028 and Eurocode 3 Part 3.1, but it can also be determined by numerical methods. For that purpose modelling using CFD proved to be both accurate and reliable. In this study the fluid-flow around the segment of a power transmitter was simulated by a 3-D model, where the geometry of the segment is approximated with a porous structure having the appropriate factor of porosity, in order to simplify the geometry. We have used three representative models of turbulence, standard k-? model, RNG k-? model, and Reynolds stress model. Drag coefficient values are extracted from the flow field and compared for all studied cases and with available experimental results from the wind tunnel. Simulations were performed for four wind velocities between 10 m/s and 30 m/s. The results are supplemented by the ones obtained by artificial neural network. The aim of this study is to show how the simple turbulence model coupled with approximated geometry can be used in the analysis of the aerodynamic forces acting on the lattice structure.
Initial development of the hybrid semielliptical-dolphin airfoil

Published: July 2021

Iosif Taposu has formulated a mathematical model and generated a family of airfoils whose geometry resembles the dolphin shape. These airfoils are characterized by a sharp leading edge and experiments have proven that they can achieve better aerodynamic characteristics at very high angles of attack than certain classical airfoils, with the nose geometry inclined downwards. On the other hand, they have not been applied to any commercial general aviation aircraft. The authors of this paper have been motivated to compare the aerodynamic characteristics of widely used NACA 2415 airfoil with Taposu?s Dolphin that would have the same principal geometric characteristics. A CFD calculation model has been established and applied on NACA 2415. The results were compared with NACA experiments and very good agreements have been achieved in the major domains of lift and polar curves. The same CFD model has been applied on the counterpart Dolphin 2415. Results have shown that the Dolphin has a slightly higher lift/drag ratio in the lift coefficient domain 0.1-0.35 than NACA. On the other hand, at higher and lower lift coefficients, its aerodynamic characteristics were drastically below those of the NACA section, due to the unfavorable influence of the Dolphin?s sharp nose. A series of the Dolphin?s leading edge modifications has been investigated, gradually improving its aerodynamics. Finally, version M4, consisting of about 70% of Dolphin?s original rear domain and 30% of the new nose shape, managed to exceed the NACA?s characteristics, thus paving the way to investigate the Dolphin hybrids that could be suitable for the general aviation industry.

Published: July 2021

The mVINIS ion source, a part of FAMA installation at Vinca Institute of Nuclear Sciences, is able to produce multiple charged heavy ion beams through the utilization of vapors created by the process of melting solids inside the miniature oven (mini-oven). The mini-oven that was used previously could only reach the maximum temperature of 800?C, which is far too low for evaporating most metals. For this purpose, a higher operating-temperature of 1500?C was needed. Our study focuses on numerical finite element method analysis of the temperature distribution of newly designed mini-oven.

Persons living with HIV (PLWH) manifest chronic disorders of brown and white adipose tissues that lead to diabetes and metabolic syndrome. The mechanisms that link viral factors to defective adipose tissue function and abnormal energy balance in PLWH remain incompletely understood. Here, we explored how the HIV accessory protein viral protein R (Vpr) contributes to adaptive thermogenesis in two mouse models and human adipose tissues. Uncoupling protein 1 (UCP1) gene expression was strongly increased in subcutaneous white adipose tissue (WAT) biopsy specimens from PLWH and in subcutaneous WAT of the Vpr mice, with nearly equivalent mRNA copy number. Histology and functional studies confirmed beige transformation in subcutaneous but not visceral WAT in the Vpr mice. Measurements of energy balance indicated Vpr mice displayed metabolic inflexibility and could not shift efficiently from carbohydrate to fat metabolism during day-night cycles. Furthermore, Vpr mice showed a marked inability to defend body temperature when exposed to 4°C. Importantly, Vpr couples higher tissue catecholamine levels with UCP1 expression independent of β-adrenergic receptors. Our data reveal surprising deficits of adaptive thermogenesis that drive metabolic inefficiency in HIV-1 Vpr mouse models, providing an expanded role for viral factors in the pathogenesis of metabolic disorders in PLWH.

OBJECTIVE

Clinical guidelines for people with diabetes recommend chronic kidney disease (CKD) testing at least annually using estimated glomerular filtration rate (eGFR) and urinary albumin-to-creatinine ratio (uACR). We aimed to understand CKD testing among people with type 2 diabetes in the U.S.

RESEARCH DESIGN AND METHODS

Electronic health record data were analyzed from 513,165 adults with type 2 diabetes receiving primary care from 24 health care organizations and 1,164 clinical practice sites. We assessed the percentage of patients with both one or more eGFRs and one or more uACRs and each test individually in the 1, 2, and 3 years ending September 2019 by health care organization and clinical practice site. Elevated albuminuria was defined as uACR ≥30 mg/g.

RESULTS

The 1-year median testing rate across organizations was 51.6% for both uACR and eGFR, 89.5% for eGFR, and 52.9% for uACR. uACR testing varied (10th–90th percentile) from 44.7 to 63.3% across organizations and from 13.3 to 75.4% across sites. Over 3 years, the median testing rate for uACR across organizations was 73.7%. Overall, the prevalence of detected elevated albuminuria was 15%. The average prevalence of detected elevated albuminuria increased linearly with uACR testing rates at sites, with estimated prevalence of 6%, 15%, and 30% at uACR testing rates of 20%, 50%, and 100%, respectively.

CONCLUSIONS

While eGFR testing rates are uniformly high among people with type 2 diabetes, testing rates for uACR are suboptimal and highly variable across and within the organizations examined. Guideline-recommended uACR testing should increase detection of CKD.

Podocyte injury is important in development of diabetic nephropathy (DN). Although several
studies have reported single
cell-based RNA-seq of podocytes in type 1 DN (T1DN), the podocyte translating mRNA profile in type 2 DN
(T2DN) has not been previously compared to
that of T1DN. We analyzed the podocyte translatome in T2DN in podocin-Cre; Rosa26fsTRAP;
eNOS-/-; db/db mice and compared it to streptozotocin-induced T1DN in podocin-Cre; Rosa26fsTRAP; eNOS-/-
mice utilizing Translating
Ribosome Affinity Purification (TRAP) and RNA-seq. Over 125 genes were highly enriched in the podocyte
ribosome. More podocyte
TRAP genes were differentially expressed in T2DN compared to T1DN. TGF-β
signaling pathway genes were upregulated while
MAPK pathway genes were downregulated only in T2DN while ATP binding and
cAMP-mediated signaling genes were
downregulated only in T1DN. Genes regulating actin filament organization and apoptosis increased while genes
regulating VEGFR signaling and glomerular
basement membrane components
decreased in both type 1 and type 2 diabetic podocytes. A number diabetes-induced genes not previously been
linked to podocyte injury were confirmed in both mouse and human DN. Differences and similarities in the podocyte
translatome in T2DN and T1DN can identify factors underlying the
pathophysiology of DN and novel therapeutic targets to treat diabetes-induced podocyte injury.

Az elektronikai hadviselés (EHV) a rádió és a rádiólokátorok elterjedésével, valamint katonai műveletekben történő alkalmazásával a 20. század elején és középső évtizedeiben jelent meg. Megelőzte a kiberhadviselést, amelynek célja egy állam vagy egy szervezet információs rendszereinek stratégiai szintű, katonai célú, szándékos támadása. E tevékenység csak évtizedekkel később, a számítógépek és az internet feltalálása nyomán indult fejlődésnek. Napjainkban vannak átfedések az elektronikai­ és a kiberhadviselés között, de kulcsfontosságú különbségek is megfigyelhetők. Míg a kiberhadviselés nem lehet sikeres a jól megtervezett és védett, a globális kibertérrel csak nagyon korlátozott adatkapcsolattal rendelkező katonai rendszerek ellen, addig a korszerű elektronikai harc (EHC) rendszerek behatolhatnak az ilyen típusú „erődítményekbe”. 2017­ben, egy év előkészítés után, indult el a Magyar Honvédség elektronikai hadviselés­fejlesztési programja, amelynek célja a rádióelektronikai felderítő és zavaróképesség megújítása. A Magyar Honvédség modernizációjának sikere alapvetően az újonnan megjelenő műszaki lehetőségek és katonai alkalmazások, szakmai kiszolgálásától és felhasználásától függ.

The Influence of Maternal Childbirth Experience on Early Infant Behavioural Style
Authors:   , Power Carmen
Published: July 2021

The use of interventions during childbirth is increasing (WHO, 2018) and, while such interventions can be life-saving, they may have a negative impact on the mother’s experience of birth and her psychological wellbeing post birth. They may also adversely affect the newborn infant’s physiology and behaviour (Taylor, Swift & Glover, 2000; Gitau et al., 2001; Douglas & Hill, 2013). However, little is known about whether the birth and early postnatal experiences influence infant behavioural style (known as temperament) (Thomas & Chess, 1977) beyond the initial postnatal period. Employing an exploratory mixed methods approach, the overarching aim of this thesis was to explore how any potential impacts of birth experience on newborn infant behaviours may occur, and if so, whether they persist beyond the neonatal period; as well, to explore how the mother’s response to her birth experience might mediate such effects. Part One involved a qualitative exploration of the experiences and beliefs of eighteen health professionals and twenty-two mothers in relation to childbirth and early infant behavioural style. Health professionals interviewed in Study One believed that the birth experience could have a direct impact on newborn wellbeing and behaviour as well as influencing it indirectly via the mother’s response to the birth and her subsequent perceptions of and interactions with her baby. In contrast, most of the mothers interviewed in Study Two did not perceive any association between their birth experience and their baby’s early behavioural style. However, a simple content analysis highlighted strong patterns in the data between reported maternal physical and emotional birth experiences and perceived infant temperament during the first year. Part Two (Study Three) involved a detailed online survey of approximately a thousand mothers, employing quantitative methods of analysis. Although physical birth factors contributed to the newborn baby’s response (e.g. alert-content or cry-fuss behaviours), it was subjective and psychological birth factors that predicted ongoing infant behavioural style (0-6 months), for example alert-responsive or unsettled, irritable infant behaviours. Taken together, the data suggest that subjective and psychological factors could be as important as objective physical factors in post-birth mother-infant wellbeing and developing infant temperament. These findings may have important implications for future maternity and perinatal care of mothers and their infants.
Holographic Aspects of Chaos and Integrability in String- and M-Theory
Authors:   , van Gorsel Jeroen
Published: July 2021

In this thesis we investigate classical integrability of the string worldsheet on diﬀerent super-gravity backgrounds. We focus in particular on the class of half-supersymmetric AdS7 solutions of Massive Type IIA supergravity, that are thought to be the near-horizon limit of a D6-D8-NS5 Hanany-Witten brane set-up, and are dual to six-dimensional conformal ﬁeld theories with N = (1, 0) supersymmetry. We use both analytical and numerical methods to show the (bosonic sector of the) string worldsheet is non-integrable on most of these backgrounds. The backgrounds on which the string is integrable are an inﬁnite massless solution (corresponding to an inﬁnite constant quiver), and a background corresponding to an inﬁnite linear quiver theory.In addition we ﬁnd that the (bosonic sector of the) string is integrable on a background that we call AdS7 × (S3)λ. For this background we show that it corresponds to a 6d SCFT with an inﬁnitely long quiver with an inﬁnite number of ﬂavour groups, all proportional to the colour groups. We study this particular supergravity background in detail, and suggest it corresponds to the large-N limit of the dual SCFT in the limit where the Chern-Simons level k goes to inﬁnity.This integrable AdS7 × (S3)λ background can be obtained as the λ-deformation of AdS7×S3. In this context we study integrable deformations of supergravity backgrounds in the last part of this thesis, in particular non-Abelian T-duality. We present another back-ground on which the string is integrable by performing two non-Abelian T-dualities on two three-spheres inside the AdS5×S5 solution and study the resulting background.

No presente trabalho, através da modelagem matemática, analisa-se o comportamento das abelhas através da dança conhecida como do requebrado. Esta dança é indicadora de fontes de alimento e, portanto, o objetivo deste trabalho tem sido entender o forrageamento e a distância da fonte de recursos alimentares, com base nas formas de comunicação (dança). O trabalho tem sido realizado por um grupo de estudantes em forma interdisciplinar apoiado por duas professoras entre os meses de agosto a dezembro de 2019. Curvas paramétricas com formato do número oito, foram a forma de idealizar a dança e a dinâmica da comunicação da localização e distância da fonte de alimento, construídas no software GeoGebra para entendimento da modelagem nas perspectivas do desenvolvimento matemático dentro da colmeia.

Purpose. The aim of the research presented in this article is to analyze the features of the reflection of the damage to the territory of the Transcarpathian region by landslide processes based on the anomalies in the magnetic and gravitational fields, taking into account tectonic zoning. The study is an important stage in predicting the landslide processes and it is aimed at reducing their negative effects on the environment. The relevance of the research is due to the growing intensification of landslides in the Carpathian region of Ukraine. Methodology. The development of landslides in each structural-tectonic zone is associated with its tectonic structure, and therefore these processes can have different intensity, dynamics, tendencies for further development and distribution area. Lithological-facies composition and bedding conditions of rocks form the physical and mechanical properties of rocks, determining the rate and mechanism of the development of landslides. The spatial confinedness of landslide processes in the fault zones is reflected in the gravitational and magnetic fields. Results. With the help of GIS MapInfo tools, a number of landslides in each tectonic zone, anomalies in the gravitational and magnetic fields, areas affected by landslides, the distance to the fault zones were calculated. The important result of the research is to prove a direct correlation between the spatial distribution of landslides and fault zones, tectonic structure, the lithological composition of rocks, which are reflected in gravimagnetic anomalies. Scientific novelty. The peculiarities of the reflection of the tectonic structure, zones of decompression, fragmentation of rocks and lithological composition in gravimagnetic fields on a regional scale are examined, and their association with landslide processes is evaluated for the first time. Practical significance. The theoretical substantiation of the peculiarities of the behaviour of gravimagnetic fields in the zones of distribution of landslide processes makes it possible to assess the natural conditions for the formation and development of landslides in a given region. The connection between the impact of the fault zones on landslide processes by their reflection in gravimagnetic fields is established, which can be used in the future for spatial forecasting of the development of landslides in territories with related structural-tectonic conditions.

İçinde bulundukları dönemin; duygu, düşünce ve yaşam koşullarına göre şekillenen ve o döneme ilişkin önemli birer somut kaynak rolü üstlenen tarih çevreler, kültürel peyzajın önemli bileşenlerindendir. Bu bağlamda sürdürülebilirliklerinin sağlanması da önem taşıyan bir yaklaşım olarak benimsenmelidir. Tarihi çevrelere ilişkin korumada konut ve bahçesi gibi en küçük ölçekten, sokak, doku, kent, bölge gibi en büyük ölçeğe doğru yapısal ve doğal peyzajları içine alan bütüncül koruma anlayışı ile hareket edilmesi; restorasyon vb. yenileme işlemlerinin bu çevrede gerçekleştirilmesi gerekmektedir. Ancak, gerçekleştirilen çalışmalarda konut bahçesine yönelik restorasyon çalışmalarına yeteri kadar önem verilmediği gözlemlenmiştir. Çalışma kapsamında, Tarihi Kentler Birliği’ne üye olan Bartın kentinde yer alan tescilli yapılardan Hacı Eminler konut bahçesi araştırma alanı olarak seçilmiştir.

Performance Benchmarking for NoSQL Database Management Systems
Authors: Andor C.-F.
Published: July 2021

NoSQL database management systems are very diverse and are known to evolve very fast. With so many NoSQL database options available nowadays, it is getting harder to make the right choice for certain use cases. Also, even for a given NoSQL database management system, performance may vary significantly between versions. Database performance benchmarking shows the actual performance for different scenarios on different hardware configurations in a straightforward and precise manner. This paper presents a NoSQL database performance study in which two of the most popular NoSQL database management systems (MongoDB and Apache Cassandra) are compared, and the analyzed metric is throughput. Results show that Apache Cassandra outperformes MongoDB in an update heavy scenario only when the number of operations is high. Also, for a read intensive scenario, Apache Cassandra outperformes MongoDB only when both number of operations and degree of parallelism are high.
Temporal Discounting for Multidimensional Economic Agents
Authors: Bota F.
Published: July 2021

Individuals frequently place a higher value on money and goods today than they would in the future. This is known as temporal or time discounting, and most economic models include discount functions to represent such utility over time. In this paper we evaluated traditional models with experimental data from the scientific literature and constructed our own samples for comparison.

In addition, we evaluated the prediction accuracy of the models and proposed new hybrid solutions. Our investigation aims to contribute to a better understanding of human nature in complex processes.
Los efectos de los choques macroeconómicos en el empleo: el caso de México
Authors: Campos Vázquez Raymundo M.
Published: July 2021

Se estudian los efectos de choques macroeconómicos en empleo y salarios para el caso de México. Encontramos que trabajadores jóvenes y menos calificados son los más afectados por un choque económico en términos de desempleo, participación en la fuerza laboral y empleo en el sector informal. Se deriva un modelo teórico para estudiar los efectos de choques macroeconómicos en salarios y composición de empleo. Los resultados teóricos implican que las elasticidades de la oferta laboral en el sector formal e informal son cercanas a 0.75 y 0, respectivamente, y que ambas elasticidades de la demanda laboral son cercanas a 1.
Método para el proyecto de diseño industrial

En nuestro medio el uso indiscriminado de la palabra metodología ha generado confusiones que entorpecen el entendimiento de dicha disciplina. En primer lugar, constantemente son confundidos método con metodología; esto es, se dice "las metodologías" (en plural), para designar diversos métodos, cuando en realidad existe una sola metodología (en singular) y no varias, entendiendo a ésta como el estudio de los métodos (en plural). Una confusión parecida suscita los términos técnica, estrategia, modelo, teoría, procedimiento y fase. Es común oír decir a los diseñadores que "llevaron a cabo un método", cuando, en realidad, lo que hicieron fue aplicar una técnica en cierta fase del proceso de diseño. La técnica del brainstorming o "lluvia de ideas", muy popular en una época, es catalogada frecuentemente como método de diseño, aun en escritos respetables acerca de la metodología de diseño.1 Cuando autores como Nigel Cross (1999) hablan sobre "métodos de diseño" lo hacen para describir las técnicas y estrategias más comunes utilizadas en el diseño, en las cuales, obviamente, está el dibujo. Algo semejante sucede cuando alguien dice que "ha aplicado una metodología", cuando lo que hizo fue seguir los pasos e indicaciones de un método en particular, sin que exista un estudio de la estructura general de los métodos de diseño. Es común, asimismo, la confusión que produce la palabra proceso cuando se relaciona con el método del diseño. A primera vista hablar de método implica siempre un determinado proceso.
