Digital Rights and Digital Currency in Russian Law: The Issues of Legal Nature and Relations
Authors:   Novosibirsk State National Research University, Zaynutdinova Elizaveta
Published: December 2022

Introduction: currently, all countries are facing the challenges of the legal regulation of new digital phenomena that receive various names – digital rights, tokens, digital assets, digital currency, cryptocurrency. The Russian legislator has chosen the concepts of digital rights and digital currency as fundamental in this area. Questions arise about the correlation of such objects of rights, the selection of their qualifying features and the definition of the features of their legal regimes in the Russian Federation. The purpose of the study is to identify significant qualifying features of digital rights and digital currency, allowing them to be distinguished from each other in the Russian legal field. In this regard, the following research tasks are solved: 1) the definition of the essence of digital rights and digital currency in Russian law and similar legal phenomena; 2) the identification of qualifying features of digital rights and digital currency in the legislation, doctrine and law enforcement practice; 3) the comparative legal analysis of the legal regimes of digital rights and digital currency; 4) providing recommendations to the legislator and law enforcement officer on a more precise definition of the legal nature of digital rights and digital currency and a more effective legal regulation of their movement in the Russian Federation. Methods: in carrying out the study, the formal legal, historical legal and comparative legal methods were used to formulate the features of the legal regimes of digital rights and digital currency in Russian law. Results: digital rights and digital currency, despite the presence of a single digital (binary) form, have different legal regimes. Digital rights are second-order rights, being binding and other rights in digital form. In the case of digital rights, there is an obligor on whom the creditor has the right to make a corresponding claim. Accordingly, digital rights are relative rights. In turn, the digital currency is limited in circulation, at the same time, it seems more correct to recognize it as a special right of obligation, while the obligor is the user of the information system in which the digital currency is issued and circulated. Such a digital currency should not be confused with a digital currency issued by the Central Bank acting as an obligor. The authors have come to the conclusion that digital rights and digital currency are similar in having a digital form, which determines the civil remedies and liability applied in their movement relations, as well as the use of special contractual structures (smart contract). The differences between digital rights and digital currency lie in the definition of the obligor in the obligation, whose object is a digital right or digital currency.

Authors:   Institute of State and Law of the Russian Academy of Sciences, Rossinsky Sergey
Published: December 2022

Introduction: the transformation of the pre-trial proceedings system predicted recently can be planned after a proper assessment of the available organizational and legal resources, a genuine understanding of their role and potential in solving various tasks of combating crime. In this regard, the purpose of the paper is to determine the essence of the bodies of inquiry in the general system of the criminal procedure regulation and to identify the reasons for their being given a number of police powers: to carry out the actual attachment of a person, to conduct operational investigative measures, in particular, the search for the accused. Methods: the methodological framework for the paper consists of general scientific (dialectical, systemic, structural-functional, logical, etc.) and specific scientific (formal-legal, comparativelegal, historical-legal, prognostic, etc.) research methods. The results of the study allow revealing the main reason that has influenced the mixing of procedural and non-procedural (police) powers of the bodies of inquiry – an inadequate assessment by the legislator of the results of the gradual giving the sort of police law enforcement agencies some judicial and investigative powers. Conclusions: investigative or judicial orders on carrying out operational-search and administrative-legal measures should be addressed not to the body of inquiry as a subject of the criminal procedural regulation, but to the police and other sort of police bodies given the required state authority.

Authors:   P.N. Lebedev Physical Insitute of the Russian Academi of Sciences, Pozdneev Sergey
Published: December 2022

A methods of numerical solution of the Faddeev equations for the bound and scattering state problems are presented. To solve the Faddeev’s equations with corresponding boudary conditions the mrthod is used wich is a generalization of the cooon scheme of solution of Schrodinger equations. In this method a finit-difference approximation of equations in polar coordinates is used. By means of the net with knots on the arc and knots on the beam the finit-difference approximation of Faddeev’s equations is performed. The increase the calculation accurace and to provide an effetive operation of the corresponding software support the net knots must be located nonuiformly are disscased. The net must be dens in the regions adjacent to an axes x = 0, while at → ∞ becomes less dense. Such an arrangment of the net rnots is necessary for sufficienty accurate description of the complex behaviour of wave function in the region, where x ≪ y. In the region → ∞ the wave function takes asymptotical depends smoothly on angular variable, hence in this region the net must be chosen to be less dense. At calculations on the inhomogeneous net, in very important to comply with the condition of self-consistence, which implies that the error due to introducing the cut off radius must be far less than the quantizing error in the vicinty of boundary. The stability and self-consistence of the calculations may be check by various methods determinations of the net, the cut off radius and the scattering amplitude. This approach to the numerical solution of the Faddeev’ equations combines the advantages of integral equations (the solution existens and uniqieness) with the computational scheme simplicity. Also it has the advantage that unknow two-particle quantities are specified not T-matrices but potentials and eigenfunctions corresponding to the bound states. The simplicity of the computational algorithm allows to consider few-body problems in real systems. The results of calculations binding energies and scattering state of are presented.

Published: December 2022

Abstract Molecular appraoch for identification of unknown species by using Cytochrome b gene is an effective and reliable as compared with morphological based identification. For DNA barcoding universal molecular genes were used to identify the species. Cytochrome b is a specific gene used for identification purpose. DNA barcoding is a reliable and effective method compared to the different traditional morphological methods of specie identification. So,in the present study which was conducted to identify the species, a total of 50 fish samples were collected from five different sites. DNA was extracted by using the Phenol Chloroform method from muscle tissue. Five sequences were sequenced (one from each site), analyzed, and identified specific species as Pangasius pangasius. Identified sequences were variable in length from 369 bp (Site 1), 364 bp (Site 2), 364 bp (Site 3), 352 bp (Site 4), and 334 bp (Site 5). Identity matches on the NCBI database confirmed the specific specie as P. pangasius. A distancing tree was drawn to show maximum likelihood among the same and different species. Yet, in many cases fishes on diverse development stages are difficult to identify by morphological characters. DNA-based identification methods offer an analytically powerful addition or even an alternative tool for species identification and phylogenetic study. This work intends to provide an updated and extensive overview on the DNA based methods for fish species identification by using Cytochrome b gene as targeted markers for identification purpose.

Published: December 2022

Resumo Este artigo trata da promoção da leitura na escola. Há diversas razões teóricas e evidências prévias a favor da integração do movimento físico no processo de ensino-aprendizagem. Busca-se entender se essa integração é plausível especificamente para a aprendizagem da leitura e como ela pode ocorrer. Por meio de uma revisão de literatura, considerando predominantemente estudos da Alemanha, objetiva-se identificar as razões relacionadas ao processo da leitura, da alfabetização e do letramento. Discutem-se as razões à luz do modelo de processamento textual de Walter Kintsch e Teun van Dijk e da teoria de rubicão de Heinz Heckhausen. Apresentam-se razões a respeito de processos cognitivos de leitura, da volição e da motivação que apoiam o pressuposto de que a aquisição da competência de leitura recebe estímulos importantes pela oferta de aulas em movimento. É plausível que a inserção de movimento atue sobre os objetivos que o leitor quer alcançar por meio da leitura. A autoestima corporal parece ter um impacto positivo na volição pela leitura e uma influência no autoconceito do leitor. Expõem-se também algumas atividades de ensino e aprendizagem para aulas fisicamente ativas de leitura ao nível da alfabetização e do letramento, encontradas na literatura específica. Realiza-se uma diferenciação entre atividades de ensino e aprendizagem em movimento que acompanham a aprendizagem e que a facilitam.

Published: December 2022

We have investigated the process of deposition of protective boron-based thin films by electron-beam evaporation of the solid boron target. The spatial distribution of vapor of the evaporated target, temperature during deposition, and the thickness of the deposited coating have been studied, showing that higher deposition rates, coating thicknesses, and substrate temperatures were achieved at small angles (< 20 degrees) and distances (< 7 cm) between the beam and the target. The study of mass-to-charge composition of the beam-produced plasma, morphology, and the elemental analysis of the deposited coatings have demonstrated the high ratio of boron in plasma and in the coating, which has a high degree of uniformity. These findings open up possibility to use such coatings as a hard, wear-resistant top layer in multilayer combined protective and functional coatings.
State space model of undrained triaxial test data for Bayesian identification of constitutive model parameters
Authors: Tang Chang , Cao Zi-Jun , Hong Yi , Li Wei
Published: December 2022

Soil constitutive model parameters can be identified from triaxial test data. The identification is frequently performed by fitting a constitutive model to triaxial test data from a purely statistical or probabilistic perspective based on an assumption that measurements are independent. This ignores the sequential attribute of triaxial test data and is, hence, not realistic. In this paper, a probabilistic state space model (SSM) is proposed for undrained triaxial test data analysis, with which the sequential data attribute is explicitly considered and a constitutive model (physics) is linked to the SSM model (statistics) in a natural way. Then, constitutive model parameters can be rigorously learned under a Bayesian framework based on the SSM without artificially augmenting them into hidden variables of SSM. Without loss of generality, the modified Cam Clay (MCC) model is taken as an example to develop the SSM and to demonstrate the proposed Bayesian framework, which is illustrated using simulated and real-life data. Results from the proposed Bayesian framework based on the SSM include not only the best estimates of MCC model parameters but also their posterior distributions for quantifying the identification uncertainty, based on which the identifiability of MCC model parameters is discussed and highlighted.

Authors: ÇAPA Esma , ŞİMŞEK Bedia
Published: December 2022

In this study, the properties of dry clotted creams produced in different drying systems (vacuum and tray drying systems) and traditional methods have been determined. Physico-chemical, color, textural, microbiological, and sensory analysis as well as fatty acid composition analysis and appearance analysis of dry clotted creams were carried out during storage. During the storage, it was observed that pH and titration acidity values of samples increased. The hardness levels of the clotted cream produced with the tray dryer were found to be higher than the vacuum and traditional methods. The highest ratio of saturated fatty acids was observed in the samples produced with a vacuum dryer. As a result, it was faund that a product similar to traditional dry cream could be produced in industrial tray drying systems. When vacuum drying was applied, more successful results were obtained against oxidation than other drying techniques. However, it was determined that some of its features were also lost. It was also determined that in this system, the dry cream production time may be shortened by at least 50 % compared to the traditional production.

Published: December 2022

I am presenting the career of my dentist grandfather, Dr Pál Sztrilich in my article. My grandfather lived and worked in the first half of the 20th century. A number of innovations are associated with his name, including the tooth crown remover called “strilich”, which is still in use in dental practices. In addition to his work as a dentist, he regularly published articles on practical issues of dentistry. He was a pioneer in dental X-ray procedures and in the training of assistants, which was rather underdeveloped in those days. His whole career was determined by pragmatism. Most of his articles deal with everyday tasks, e.g., how to run a patient-friendly dental office in the most efficient way

Published: December 2022

The biological indicators of Chrysichthys walkeri (Claroteid catfishes) in lake Volta were investigated for their sustainable management. A total of 846 samples were collected from the lake from March to December 2020. The recorded total length of the fish samples was analyzed using TropFishR. The von Bertalanffy parameters including asymptotic length (L∞), growth rate (K), and growth performance index (Φ) were estimated as 28.88 cm, 0.42 per year, and 2.54 respectively. Mortality parameters were calculated as total mortality rate (Z) = 2.56 per year, natural mortality rate (M) = 0.91 per year and fishing mortality rate (F) = 1.65 per year. The exploitation rate (E) was 0.64. From the study, it was concluded that the population of the species C. walkeri from the Lake Volta is overexploited. There is the need to ensure continuous monitoring of fishing effort to ensure the sustainable exploitation and management of C. walkeri.

Authors: GÜHER Hüseyin
Published: December 2022

The present study focused on monthly densities and abundances of planktonic microcrustaceans (Cladocera and Copepeda) in Kırklareli reservoir, as well as their relationship with some physicochemical parameters at three stations for the period from May 2018 to April 2019. In the present study, a total of 26 planktonic microcrustaceans species, 14 from Cladocera and 12 from Copepoda were identified. The mean annual microcrustacean abundance recorded during the study was 24076 ind/m3, 67% of which was Cladocera (16054 ± 12414 ind/m3) and 33% was Copepoda (8022 ± 5564 ind/m3). The maximum abundance of planktonic microcrustaceans were found in September (51521 ind/m3) and the minimum was found in January (2919 ind/m3). The most common species in the reservoir were Bosmina longirostris, Daphnia pulex, Daphnia cucullata, Daphnia galeata, Daphnia longispina and Diaphanosoma brachyurum from Cladocera and Cyclops abyssorum, Cyclops vicinus, Eudiaptomus vulgaris and Arctodiaptomus wierzejskii from Copepoda. The environmental parameter values measured in the reservoir were acceptable to support aquatic life, especially the zooplankton community. The total density and abundance of zooplanktonic microcrustaceans showed positive correlation with the water temperature and Chlorophyll-a. According to these results, we concluded that Kırklareli reservoir has a mesotrophic character in terms of the microcrustacean fauna and the physicochemical parameters.
Determinants of Successful Crowdfunding Campaigns: Evidence from Russian Crowdfunding Platform Boomstarter
Authors: Макарова Светлана Геннадьевна , Улитина Дарья Алексеевна
Published: December 2022

According to practice, about half of the projects on crowdfunding sites (based on rewards) do not collect the declared amount of funding. This is largely due to the lack of experience in running crowdfunding campaigns and ignoring important factors that are important to take into account when managing crowdfunding campaigns. Many foreign publications have studied the nature of the influence of various determinants on the success of fundraising on crowdfunding platforms, in particular, on Kickstarter, Indiegogo, Ulule, Eppela and others. As for research on Russian crowdfunding platforms, there is an extremely small number of such studies. Based on the construction of OLS regressions for 300 projects from July 2020 to May 2022 by the end date of the project from the Russian crowdfunding platform Boomstarter, we firstly obtained that such determinants as choosing a reasonable financial goal of the project, the number of sponsors, the numberof project comments and the availability of video materials about the project have a positive impact on the success of the crowd campaign. In addition, we have developed a model based on logit regression testing, which has a high predictive power. This model can be used to predict the results of a crowd campaign with given parameters.

In further research in this area, it is possible to increase the number of observations, change the set of factors that potentially affect the success of a project’s fundraising on crowdfunding platforms, and also consider the influence of factors depending on the category of the project. A promising area of research is the analysis of social interactions between investors in the framework of crowdfunding campaigns and the identification of the nature of the dependence of the volume of collected financial resources throughout the entire project financing cycle in the Russian market.

Üretim sistemleri için darboğaz üretim verimliliğini kısıtlayan en etkili faktörlerden biridir. Darboğaza sebep olan bir süreç daha hızlı çalışır ise tüm hattın üretim hızı artacak ve böylelikle üretim süreçlerinin ve tedarik zincirinin devamlılığı sağlanacaktır. Bu sebeple darboğazın tespit edilmesi ve kontrol altına alınması işletmeler için önem kazanmıştır. Literatürde bu konuda çok sayıda yöntem ve çalışma bulunmaktadır. Bu çalışmanın amacı ise literatürde bulunan darboğaz tespiti çalışmalarının incelenmesi, kullanılan yöntemlerin açıklanması ve analiz edilmesidir. Çalışma kapsamında 2007-2022 yıllarına ait toplam 48 makale incelenmiştir. İncelenen çalışmalardan elde edilen sonuçlara göre darboğaz tespitinde en çok benzetim yönteminin kullanıldığı görülmektedir. Aynı zamanda dönüm noktası yöntemi, aktif dönem yöntemi ve matematiksel yöntemler de darboğaz tespitinde diğer yöntemlere göre daha fazla kullanılmaktadır. Son yıllarda ise artan yapay zeka çalışmaları ile birlikte makine öğrenmesi tabanlı yaklaşımlar kullanılmaya başlanmıştır. Literatürde bu kadar sayıda darboğaz tespit yönteminin açıklandığı ve bu konudaki çalışmaların derlenip analiz edildiği bir çalışma bulunmamaktadır. Bu sebeple yapılan çalışmanın ilgili araştırmacılara yol göstermesi hedeflenmektedir.

HEAT INPUT EFFECT OF THE FCAW PROCESS ON THE MICROSTRUCTURE AND MECHANICAL PROPERTIES OF STRUCTURAL STEEL JOINTS
Authors: GÜROL Uğur
Published: December 2022

Flux-cored wires are commonly used in structural and pipeline welding, shipbuilding, offshore constructions, and petrochemical and power generation industries. The higher heat inputs in the multi-pass welding result in shorter production time while considerably changing the properties of the welded joint. In this study, robotic flux cored arc welding with varying heat inputs (between 0.56-2.52 kJ/mm) was performed to determine the effect of heat input on weld microstructure, hardness, tensile properties, and impact toughness in the structural steel joints. Results exhibited that decrease in heat input from 2.52 to 0.56 kJ/mm changed the majority of the microstructure from polygonal ferrite to acicular ferrite. Furthermore, this increased by 56%, 37%, and 47% in yield strength, tensile strength, and hardness values, respectively, while decreasing by 30% and 15% in elongation and Charpy impact test results, respectively. Moreover, all welded joints displayed a satisfying toughness value higher than the requested value of 47 J, even at the test temperature of -50 °C. Finally, it can be concluded that the optimum results were obtained with a heat input of 1.26 kJ/mm, considering the minimum requirements of the AWS A5.20 standard and the expectations in applications.

El desarrollo como proyecto constituyente de la modernidad es un campo de estudio y de acción gubernamental y social problemático. Por un lado, las políticas y programas de desarrollo en los países llamados del tercer mundo, del sudeste global, del norte excluido o de las periferias del capitalismo no han servido ni para la eliminación de las desigualdades, ni para el mejoramiento de la calidad de la vida de millones de personas y, menos, para la reducción de la pobreza y el hambre. Especialmente, ciertos sectores de las sociedades del mundo –mujeres, etnias y minorías, infantes, jóvenes, entre otros– permanecen rezagados en educación, salud, seguridad humana, y, en general, desprovistos de los medios para su autonomía. Por otro lado, forma parte del proceso modernizador y colonial de Occidente, con las consecuentes derivaciones antropo, andro y capitalocéntricas. Supone que las poblaciones a quienes se quiere “desarrollar” viven en carencia o inadecuadamente. Aunque se ha intentado despojar el concepto de su centralidad en la economía al incluir el ambiente y focalizarlo en el ser humano, sigue siendo una idea colonial, propia de la modernidad occidental (de origen europeo y afianzada por el posicionamiento global estadounidense), que busca dominar y homogeneizar a las poblaciones locales, imponiéndoles la economía mundial dominante, el capitalismo, y apropiándose de sus recursos materiales, culturales y sociales. Este libro pretende exponer diferentes aportes a la configuración o comprensión de otros desarrollos o contradesarrollos, que se logran mediante lo que Arturo Escobar está concibiendo como “transiciones”. Estas experiencias muestran cómo el desarrollo puede ser entendido de múltiples maneras o tiene expresiones diversas, de acuerdo con su configuración sociocultural, localización y situacionalidad (espacios-tiempos propios).
Film Aesthetics in Álvaro Cepeda Samudio’s La casa grande
Authors: Vargas Trujillo Juan
Published: December 2022

Drawing on an interdisciplinary approach, this article analyzes the prevailing cinematographic aesthetics in Cepeda Samudio’s La casa grande by means of an unprecedented approach to the literary work in technical terms of cinema, such as shooting plans, spatiality, sound effects, script-type writing, and images. Thus, the purely indicative tendency which was previously used to approach the novel is expanded. The analysis is made on the basis of the author’s biographical background, his artistic influences, and his particular way of approaching a historical event and conveying it through literature. The purpose is to produce an interpretation of La casa grande as if it were a filmic realization based on concrete examples. It is concluded that these filmic characteristics are widespread and original; thus, they establish starting points for further discussions oriented to the presence of sensitive moments and fetish images in Cepeda Samudio’s work.

Published: December 2022

Preventive behavior and decision-making processes depend greatly on risk perception. Incorporating the affective component in risk assessment provides valuable information for understanding COVID-19-related risk. The study aimed to adapt and validate the COVID-19 Risk Belief Scale and evaluating Intuitive Risk Perception and its association with anxiety and worry.  A cross-sectional study was conducted analyzing data from 694 Mexican adults, which was collected through on-line platforms during 2020. The final CFA including 18 items showed adequate goodness-of-fit indices (RMSEA = 0.059, 90% CI [0.053, 0.065]; CFI = 0.95; TLI = 0.94; SRMR = 0.044) supporting a five-factor structure. Moderate levels of intuitive risk perception were found, as well as moderate to low levels of worry and somatic anxiety. Significant correlations between both measures and risk perception were observed. This study confirms the importance of the affective component within risk assessment and findings become highly significant considering the current worldwide pandemic conditions.

This study focuses on dam structures in Nigeria, its availability, features, usefulness, benefits and costs, functionality and sustainability. The gap found in World Commission on Dams (WCD) Report on Dam Development being inability to proffer solutions to problems encountered by the downstream population was highlighted and discussed also. The procedure for this research work involved use of journals, books and other related literature. It was observed that many dam projects in Nigeria are lacking in areas of feasibility studies, design and construction procedure, operation and maintenance, which resulted to dam related problems like flooding and sometimes collapse of some dams. Downstream population rather than reaping abundant dam benefits record costs since their means of livelihood is hampered, affecting their social, environmental and economic well-being. This study observed that Nigeria has large, medium and small dams which are also single and multipurpose. Environmental Impact Assessment (EIA) is recommended for each dam project and a committee should be set-up to monitor its implementation to the later, from inception to end of the project for its sustainability. This paper recommends fresh attention to dam impacts on upstream and downstream population to enable them benefit immensely from these river valley projects.

Existing single-lane free flow (SLFF) tolling systems either heavily rely on contact-based treadle sensor to detect the number of vehicle wheels or manual operator to classify vehicles. While the former is susceptible to high maintenance cost due to wear and tear, the latter is prone to human error. This paper proposes a vision-based solution to SLFF vehicle classification by adapting a state-of-the-art object detection model as a backbone of the proposed framework and an incremental training scheme to train our VehicleDetNet in a continual manner to cater the challenging problem of continuous growing dataset in real-world environment. It involved four experiment set-ups where the first stage involved CUTe datasets. VehicleDetNet is utilized for the framework of vehicle detection, and it presents an anchorless network which enable the elimination of the bounding boxes of candidates’ anchors. The classification of vehicles is performed by detecting the vehicle’s location and inferring the vehicle’s class. We augment the model with a wheel detector and enumerator to add more robustness, showing improved performance. The proposed method was evaluated on live dataset collected from the Gombak toll plaza at Kuala Lumpur-Karak Expressway. The results show that within two months of observation, the mean accuracy increases from 87.3 % to 99.07 %, which shows the efficacy of our proposed method.

Rice husk is widely recognized as significant biomass containing cellulose, lignin and silica. Usually, rice husk is combusted for energy purposes but it contributes to severe environmental pollution. Therefore, the integrated components of rice husk (i.e. silica) can be extracted and converted into value-added products. However, the metallic impurities must be removed before further extraction. Generally, rice husk is leached with conventional acids such as HCl and nitric acid, however, the present study has used aqua regia and compared the results with conventional acids. The leached rice husk samples were characterized using TGA, SEM and EDX. The results of the present work indicate that the aqua regia carries a significant leaching potential to remove metallic impurities from rice husk with 1 M and 2 M solutions removing more than 98% and 99% of impurities respectively. However, its brief chemical stability compels it to be prepared and used immediately.

Giving birth to a child is one of the precious moments in life. Every second a life is brought into the world and not many children are lucky enough to be healthy. Monitoring the health conditions of a baby in the incubator is a critical medical issue. Many researchers are working in this area to improve the safety of newborn babies. As far as the study that we proceeded with, there exists a fundamental issue in ensuring whether the doctor has attended the emergency or not. In this paper, a system is proposed to monitor the baby inside the incubator using a global system for mobile technology (GSM). The proposed system detects the baby’s temperature, heartbeat, weight, and baby’s sound inside the incubator. If there are any changes in the above-said parameters beyond the threshold level, an intimation will be sent to the concerned doctor through the GSM. The system will keep sending the alert message to the doctor every minute until the doctor acknowledges the baby’s condition. This system will enhance the safety of newborn babies by addressing the above-said issue, thereby reducing the risk involved in monitoring the babies inside the incubator. A prototype is developed and it was tested for functional verification.

A concrete box culvert with a dimension of 2.1 x 2.1 m and a concrete pipe culvert of 0.9 m diameter founded on soft soil were experiencing soil settlement causing undulation and discomfort to the traffic users. Voids that appeared beneath the culvert foundations triggering the road surface to sag. Objectives of the study are to assess the settlement of culverts underlain by soft soil using PLAXIS simulations on the initial subsoil conditions, after rehabilitation works with Polygeo foam injection and to evaluate the performance of Polygeo foam as a rehabilitation method. The settlement of the culverts underlain by the soft soil will be determined using finite element model based on the data and information obtained from geoforensic assessments including 12 nos. of deep borehole as well as soil laboratory tests. There were six culverts area undergone settlement problem, with two boreholes were executed at the side of each culvert. Throughout the five-year period of Post Construction stage with Polygeo rehabilitation works, the pipe culvert was shown to settle around 22 mm whilst the box culvert with pile settled around 14 mm. The study concluded that the rehabilitation works using Polygeo foam has been successfully reduced the rate of settlement and complied to JKR settlement criteria.

Public transportation provides basic mobility services to various types of facility actions including those involving education, employment, medical care, and recreation. The general goal of this study was to develop a model with respect to travel time. Public bus transport which connects two cities, A/Hitam- B/Pahat), was selected to conduct this study. Factors such as departure delays, route length, delays at marked traffic light intersections, delays at bus stops, and bus speeds were collected using observation methods. SPSS is a methodological tool used for statistical analysis. The results of the analysis showed a strong positive correlation of ‘0.942’ between travel time and route length, a moderate positive correlation of ‘0.697’ between travel time and delay at marked traffic light intersections, a weak correlation of ‘0.272’ between travel and departure time. delay with a significance level of 0.05. The determination coefficient showed a great regression explanatory power with R2 = 0.954. and (P <0.001). SPSS is also used to examine the data and generate models.

Nanofiber Polyethersulfone (PES) membrane fabrication using the electrospinning method incorporating dry/wet phase inversion was investigated. The electrospinning process is a straightforward and versatile method to produce one-dimensional nanostructures, especially nanofibers. The electrospun’s outcome can be affected by the various process parameters and solution parameters, making it an interesting study subject and an opportunity for customized nanofiber membrane. In this work, the analysis includes dope formulation and electrospinning parameter influence to membrane morphology dimensional structure based on Scanning Electron Microscopy (SEM) and filtration capability. Fibrous membranes were electrospun at 1 to 3 ml/h feeding rate and at 12 to 25kV voltage rate in a fixed 10 to 12 cm distance between the filter membrane and the syringe needle tip. The PES dope solution with N-methyl-2-pyrrolidone (NMP) as solvent electrospun onto a wet filter base membrane (5A 90 mm Advantec Filter Paper) to refine the fabricated fibrous membrane and to induce the dry-wet phase inversion process. The results indicate that the PES fiber dimension reduced at a lower feeding rate and higher voltage rate. In terms of liquid separation performance, experimental results showed that pure water permeation flux was reduced with the increased flow spinning rate of 1 to 3ml/hr but triple times higher than the increased concentration PES formulation, even at higher voltage spinning. The electrospun performance of polyethersulfone was also explained using Response Surface Methodology (RSM). It focused on the polymer content, tip-to-collector distance, and flow rate parameters toward fiber diameter and contact angle. Among these factors, the effect of PES content (f-value = 65.87) was the most significant, followed by tip-to-collector distance (f-value = 11.26) and flow rate (f-value = 2.59).
Confinement and spatial entanglement: phenomenology of a new interference principle
Authors: Castañeda Román Eduardo
Published: December 2022

Recently, the novel confinement principle in spatially-structured Lorentzian wells was reported to describe in a unified way the interference of classical waves and singular quantum particles in a causal framework in ordinary space. The phenomenology derived from this principle offers significant advantages over the conventional classical and quantum formalisms of interference founded on wave superposition. This paper presents a conceptual analysis of such a principle and its main implications indicating its fundamental differences from the standard descriptions.

Genus Paracoccidioides now encompasses five species, P. lutzii, P. brasiliensis sensu stricto, P. americana, P. venezuelensis, and P. restrepiensis. All the paracoccidioidomycosis (PCM) cases reported in Colombia have been classified as P. restrepiensis, which was named in honor of Angela Restrepo, a leading researcher in the field of the biology of the fungus. Previous assessments of genetic diversity have suggested that Paracoccidioides species have differences in their level of polymorphism. To infer changes in effective population size, we used the Pairwise sequentially Markovian coalescent (PSMC) by generating two pseudodiploids for P. restrepiensis and one for P. brasiliensis sensu stricto. We found that P. restrepiensis diverged from its sister species recently, the divergence time from P. venezuelensis being 125,000 (± 42,000) years. The analyses using PSMC show a systematic reduction in the effective population size of P. restrepiensis with a rapid decrease in genetic variability compared to P. brasiliensis sensu stricto, which indicates that P. restrepiensis has undergone a systematic population bottleneck. None of the other two species show the dramatic effective population size reduction observed in P. restrepiensis. These comparisons suggest that the trajectory of P. restrepiensis is somehow different from the other Paracoccidioides species and poses the question regarding the biogeographic events that have led to such a dramatic population pattern.
Ralph Cudworth

Este trabajo reconstruye el sentido de hipótesis en la filosofía de Ralph Cudworth a través del análisis de sus bases platónicas, específicamente, la estipulación de los estratos del conocimiento expuestos en la Alegoría de la línea del libro VI de República y la distinción entre objetos y disciplinas del conocimiento establecidos en Timeo de Platón. De ese modo, considero que se pueden comprender dos sentidos de ‘hipótesis’ en Cudworth a partir de la delimitación de sus funciones como 1) tipo de explicación en razón de su estatuto onto-epistemológico y 2) estrategia metodológica de indagación sobre el funcionamiento del mundo natural, sentidos que pueden colegirse de la influencia de lo que se denomina en este trabajo ‘conjetura verosímil’ para Platón, que además permite apreciar la relación existente entre la metafísica, la nueva ciencia y la moral en el siglo XVII.
