Volumetric analysis of unmodified and modified amino acids and its application to the detection of post-translational modifications (PTMs) with a nanopore
Authors: Sampath G
Published: September 2022

Recently a method was proposed for unambiguous identification of an amino acid (AA) in the bulk or at the single molecule (SM) level with a single binary measurement based on the superspecificity property of transfer RNAs (tRNAs) (doi: 10.36227/techrxiv.19318145.v3). The present report looks at detection of post-translational modifications (PTMs) in single AAs after their identification through their cognate tRNAs. The volumes of AAs with PTMs are computed from crystallographic data for all 20 proteinogenic AAs and three types of PTMs (methylation, acetylation, and phosphorylation). The ratio of the spatial volume of a modified AA to that of an unmodified one is then used to assign a PTM to the former. An experimental procedure to obtain these ratios for different PTMs with a nanopore of matching diameter is proposed. AA is freed following its identification via its cognate tRNA as in the procedure mentioned above, separated by a nanofilter, and translocated through a nanopore under electrophoresis. The ratio of the blockade level due to a modified AA to that due to the unmodified AA is compared with the theoretical ratio and a PTM assigned. Because the AA has been unambiguously determined by its cognate tRNA, PTM assignment is horizontal across the set of PTMs, thus the other 19 AA types are not involved in PTM assignment. Computational results are presented for 49 PTMs covering the three types mentioned above. Unlike most methods based on mass spectrometry this is a de novo method that does not require prior knowledge about the parent protein, nor does it use any sequence information from a proteome database.
The Sheriff in Our Minds
Authors: Director Samuel
Published: September 2022

Many people believe that our thoughts can be morally wrong. For example, many regard rape and murder fantasies as morally wrong. In a provocative recent essay, George Sher disagrees with this and argues that “the realm of the purely mental is best regarded as a morality-free zone,” wherein “no thoughts or attitudes are either forbidden or required” (2). Ultimately, Sher argues that “each person’s subjectivity is a limitless, lawless wild west in which absolutely everything is permitted” (2). Sher calls this view the Wild West of the Mind.

I argue against Sher’s position. In section I, I summarize Sher’s view. In section II, I criticize Sher’s argument for the Wild West of the Mind. In section III, I outline additional objections to Sher’s view.
Quality of Will Accounts and Non-Culpably Developed Mental Disorders
Authors: Lamb Matthew
Published: September 2022

In their article, Dylon McChesney & Mathieu Doucet (2019) argue that any viable account of the epistemic condition needs to account for the right scope of cases where an agent’s mental disorder results in exculpating ignorance. The authors then argue that this constraint on viability poses a serious problem for George Sher’s account of the epistemic condition, but not for quality of will views. In this discussion note, I do not challenge the viability constraint about mental disorder-based ignorance nor do I challenge McChesney & Doucet’s argument that Sher’s account unjustly blames many cases of disorder-based ignorance. Instead, I argue against their position that quality of will views have the resources to accurately capture the scope of cases where mental disorders lead to exculpating ignorance. I argue that quality of will views fall short because they do not take into consideration the way that a non-culpably acquired difficulty, such as developing a mental disorder in childhood, can make an expectation that the agent avoid (or correct) the disorder-based ignorance an unreasonably demanding expectation. This shortcoming results in quality of will views unjustly blaming agents for their disorder-based ignorance in some cases where the ignorance i) reflects a poor quality of will,  but ii) it would be unreasonable to expect the agent to have avoided (or corrected) the ignorance.

Published: September 2022

The evolution of a positively charged metallic macroparticle placed into the low-temperature plasma is considered. The influence of the value of the initial macroparticle charge on the dynamics of the electrical potential and temperature of the macroparticle, as well as the possibility of evaporation of a macroparticle due to its interaction with plasma particles are studied. The system of equations of the energy balance and the current balance based on the OML theory, that takes into account the changing of macroparticle potential and its temperature over the time is solved numerically. The solution of the system of equations shows the evolution of the macroparticle potential and temperature within the time interval from the moment when the macroparticle is placed in the plasma until the moment the macroparticle has charged to the floating potential. The positive charge of the macroparticle excludes the thermionic emission and secondary electron emission from the macroparticle surface, as well as the mechanisms of cooling of the macroparticle associated with these emission processes. Analytical expressions that determine the macroparticle potential, the electron current on the macroparticle, as well as the power transferred by plasma electrons in the case when the energy of attraction of electrons to the macroparticle strongly exceeds the energy of thermionic electrons, the energy of secondary electrons and the energy of plasma ions are obtained. A simplified system of equations of the energy balance and the current balance for a positively charged macroparticle is solved; the solution of the simplified equations matches with the solution of the general equations in the region of positive values of the macroparticle potential. Calculations show that during the charging of the macroparticle, its temperature increases up to the boiling point of the macroparticle substance. An equation that determines the conditions under which evaporation of macroparticles is possible has been obtained and solved numerically. The possibility of evaporation of macroparticles of a given size (critical value of the radius) due to initial charging to high positive values of potential is shown. The dependencies of the critical value of the radius on the initial value of the potential for tungsten and copper macroparticles that can be evaporated in a low-temperature plasma are obtained. These solutions bound the region of the parameters where evaporation of a macroparticle is possible and where it is not. The critical values of the potential for copper and tungsten particles with sizes of 0.1 and 1 μm are calculated. The dependence of the radius of a macroparticle on time during the process of vaporization is obtained.

Published: September 2022

In this study, the Schrödinger equation with the Hulthén plus screened Kratzer potentials (HSKP) are solved via the Nikiforov-Uvarov (NU) and the series expansion methods. We obtained the energy equation and the wave function in closed form with Greene-Aldrich approximation via the NU method. The series expansion method was also used to obtain the energy equation of HSKP. Three distinct cases were obtained from the combined potentials. The energy eigenvalues of HSKP for HCl, LiH, H2, and NO diatomic molecules were computed for various quantum states. To test the accuracy of our results, we computed the bound states energy of HCl and LiH, for a special case of Kratzer and screened Kratzer potentials, which are in excellent agreement with the report of other researchers.

Öğretmenlik birçok açıdan yeterliklere sahip olmayı gerektiren bir meslektir. Öğretmenlik mesleği, ömür boyu devam eden bir kendini geliştirme süreci olmasının yanı sıra temel kazanımların edinildiği bir eğitim süreciyle başlamaktadır. Bu sebepten eğitim sürecinin mahiyeti öğrencilerin mesleğe karşı tutumlarını da etkilemektedir. Öğretmenlik mesleği yeterlik durumu bütün branşlarda olduğu gibi İlahiyat/İslami İlimler Fakültesi mezunu öğrencilerin istihdam alanlarındaki mesleklerde de geçerlidir.

Çalışmada İlahiyat/İslami İlimler Fakültesi 3. ve 4. Sınıflarda okuyan öğrencilerin, salgın sürecinde aldıkları uzaktan eğitimle kendilerini mesleğe ne düzeyde hazır hissettiklerini belirlemek amacıyla; mesleki (Din Görevlisi ve Öğretmenlik) tutumlarıyla öz yeterlik (mesleki ve duygusal) algıları arasındaki ilişki araştırılmıştır.

Araştırmada elde edilen verilerin analiz edilmesiyle öğrencilerin %65.9’u uzaktan eğitimi verimli bulmadıklarını belirtmişlerdir. Öğrencilerin mesleki tutum puanlarıyla öz yeterlik algı puanları arasında pozitif yönlü bir ilişki olduğu sonucuna ulaşılmıştır. Öğrencilerin salgın sürecinde zorunlu uzaktan eğitimden elde ettikleri verimi değerlendirmelerinin; mesleki tutum, mesleki öz yeterlik algılarına etkisinin incelenmesi sonucunda uzaktan eğitimden elde ettikleri verim ile öğrencilerin din görevliliği tutum puanları arasında bir farklılaşma olmadığı görülmüştür. Ancak uzaktan eğitimden elde ettikleri verimi değerlendirme durumlarının öğretmenlik mesleği tutumunda, mesleki ve duygusal öz yeterlik algılarında istatistiki olarak etki ettiği sonucuna ulaşılmıştır.

Salgın sürecinde zorunlu uzaktan eğitim, eğitimin birtakım imkânlarını sınırlandırmıştır. Bu durumun öğrencilerin mesleğe karşı tutumlarını etkilediği ifade edilebilir.
HOUSING AND WELFARE ORGANIZATION OF THE PROLETARIAT IN THE CONDITIONS OF FORCED MODERNIZATION. CHALLENGES AND IMPLEMENTATION (ON THE MATERIALS OF MOSCOW)
Authors:   independant researcher, Savostkina Regina
Published: September 2022

The paper analyzes the socio-political tasks that challenged the implementation of the housing organization project in the USSR in the early 1930s, and their realization on the example of the housing arrangement for Moscow workers. In the conditions of forced industrialization, the transformation in housing and life of the working class takes on the significance of the struggle for the successes of the Five-Year Plan: it was necessary to provide such living conditions for workers that would make it possible to stop the labor fluctuation at enterprises and to cultivate ideological consciousness in the working class emerging from the peasantry. The implementation of such a task confronted a number of issues: it was necessary to determine the architectural form of the housing and communal facilities, to draw the public in the actualization of the objectives set, to find material resources for realizing the project. But it was not possible to achieve any significantresults due to the lack of actual interest, both from the public and from the authorities themselves. The lack of enthusiasm of the workers, focused on solving more pressing difficulties, led to the passivity of workers’ participation in the implementation of the housing reconstruction project. As a result, the authorities, not having the proper material resources that they would be ready to use to improve the living conditions of the workers, used repressive methods, solving the original task – to stop the labor force fluctuation.
CRIMES AGAINST CHILDREN AND ADOLESCENTS IN THE OCCUPIED TERRITORIES OF THE RSFSR DURING THE GREAT PATRIOTIC WAR (1941–1944). A REVIEW OF RUSSIAN HISTORIOGRAPHY
Authors:   Russian Academy of Sciences Institute of Russian History, Kulakov Ivan A.
Published: September 2022

Studies of crimes against the civilian Soviet population during the Great Patriotic War are one of the main areas in studying that period. However, a comprehensive research in crimes against children and adolescents has not yet been carried out – the topic of crimes against children and adolescents in most works is reflected superficially in the general context of crimes against civilians in the occupied territories of the RSFSR. Aspects of the analyzed topic are reflected in some works of Russian authors – articles and monographs. The present article is a review of Russian historiography, which reflects the problematic of the crimes of the Nazi invaders against children and adolescents. The review of the literature is systematized according to the typology of criminal acts against children and adolescents – from the use of child labor to executions and murders. In the surveyed studies, historians consider both the all-Russian and regional aspects in the problematic of the occupiers’ attitude towards the civilian population in the regions of Russia occupied by the Nazis. Despite the fact that a sufficient number of studies dealt with the topic of the occupiers’ repressive policy in relation to the civilian population, the problematic of children and adolescents is reflected in fragments and needs further research.

Published: September 2022

Any study of the boundaries of stratigraphic units in continental sequences always encounters difficulties. A sample was taken from a stratotype of the Tsagayan formation and a typical locality of the Tsagayan flora in the Amur region from crystalloclastic tuffs at the Cretaceous-Paleogene boundary to study zircon and determine its absolute age. The age of the zircons from tuffs was estimated as 68.6 ± 0.8 Ma by the lower intersection with the concordia and can be considered as close to the rock sedimentation time.

One of the difficulties to create stock control is the way to deal with the stockroom and organize stock to satisfy both on the web and offline (retailer) orders. Mostly, the current improvement of stock administration by the garment industry is yet running physically utilizing paper and notes. It causes miscalculation and loss of stock by the piece of clothing industry happened when recording the stock information. Additionally, it influences shrinkage and quality fall flat reduces which prompts the inconsistency between the recorded stock and the actual stock. The fundamental motivation behind this theory is to assemble an answer for stock administration for Garment Industry and encourages the piece of clothing industry with the Buka Gudang – Inventory Management System. Advantage from Buka Gudang – Inventory Management System for an article of the clothing industry is to improve for eliminating bottlenecks and disposal of repetitive advances can without much of a stretch be accomplished, encourage Garment Industry for a mechanized report of stock by checking stock rundown that will be refreshed electronically each time a deal is made and print out the report featuring the stock to be restocked, and Help business for keeping up the stock rundown naturally and give an exactness to each refreshed information, for example, a precise numerical estimation on Buka Gudang – Inventory Management System. Investigation measure for this postulation is finished by Data Gathering through Interview with a few dealers around Tanah Abang Jakarta who possessed a centerpiece of the clothing industry, at that point doing some perception on the stock framework and current piece of clothing industry circumstance that requirements stock administration to have the option to control the stockroom of an article of the clothing industry.

Drawing as reflection strategy for immersive virtual reality learning to enhance students’ science outcome
Authors: Hsu Ting-Yu , Chen Ming-Puu
Published: September 2022

Immersive virtual reality (IVR) technology has a great potentiality in providing high presence and in-time interactions to simulate real learning situations by presenting 3D visualization to enhance the effectiveness of learning about biology, especially genetics topics which on a submicroscopic level including genes, chromosomes, and DNAs are abstract and cannot be directly perceived or touched. In this study, different types of media learning environments, including traditional PC-slides and IVR, such as VR-game, which were employed for experiential learning of science courses with 109 students in the middle school. The purpose of this study was to investigate the effects of reflection strategy and type of media on participants’ cognitive outcomes. Significant interaction between media and methods illustrated the reflection strategy enhanced learners' cognitive performance through immersive VR learning environments (IVREs), but not traditional PC-slides. By using the drawing method, the VR-game made students the most engaged in learning and focus on the key points of important concepts; non-reflection learners focused on games and their learning was easily disturbed. It was concluded that the immersive virtual reality with the specific reflection method was effective in increasing learning performance and the drawing as a generative learning strategy indeed reduced the external cognitive load of learning and promoted the effectiveness of cognitive processing.

Published: September 2022

This paper presents an overview of the processes and tools governing the research administration in Higher Education Institutions (HEIs) in general and Qatar University (QU) in particular. It also encompasses the best practices being employed or to be adopted for smooth sailing of research projects all the way from their inception to closeout. It can serve as a referring point for management to get an eagle view of the present research policies and accordingly take decisions to boost the quality of research outcomes by implementing automated systems such as tracking and monitoring of research activities to tackle the grants in a more effective and productive manner. Moreover, the requirement of a research tracking system (RTS) has been emphasized by proposing a stepwise implementation to manage grants more efficiently both from an administration and management point of views.

In order to detail the implementation of RTS, a brief review of contemporary available grant management systems, applicable to research, has been conducted. The salient features of these systems are studied to develop an in-house solution for the university in the form of web applications using open-source tools. A tailored tracking and monitoring of research activities, from post-award until the closeout of the grants, is a valuable addition that contributes to building best practices for higher education and research institutions.

The system digitally registers the growth of the university awarded grants, in terms of research outcomes. It will intimate the projects’ leaders of their present performance with respect to their peers. The Office of Research Support (ORS) of the university on the other side can track such progress and make informed decisions to improve the performance of its grants.
Adaptive Step Size for a Consensus based Distributed Subgradient Method in Generalized Mutual Assignment Problem
Authors: Amemiya Yuki , Hanada Kenta , Sugimoto Kenji
Published: September 2022

Generalized Mutual Assignment Problem (GMAP) is a multi-agent based distributed optimization where the agents try to obtain the most profitable job assignment. Since it is NP-hard and even a problem of judging the existence of a feasible solution is NP-complete, it is a challenging issue to solve GMAP. In this paper, a consensus based distributed subgradient method is considered to obtain feasible solutions of GMAP as good as possible. Adaptive step size which is calculated by the lower and estimated upper bounds is proposed for the step size in the subgradient method. In addition, a protocol how to estimate the upper bound is also proposed, where each agent do not have to synchronize it.

Published: September 2022

With the development of the times, use the electrical devices is essential for our daily live. For using these devices, we need cables to charge or connect them. So, for people, the cables can be found almost everywhere. The cables also bring new problems, like the cables always appear in a messy form with crosses and knots. We have to tidy up the cables before using them and this is a time-consuming and tedious task. And in colleges and companies where have a large number of cables, when we clean the room or laboratory, we can always find these cables are annoying. For this reason we think that it would make our daily live more convenient to use robots to manipulate and untie the cables. Therefore, for manipulating and untying the cables, this paper proposes a method which can convert the 2D cable data from image into 3D cable data in Unity3D, where the 3D cable model is movable and can simulate the real cable, we call this 3D cable model the “Simulatable Cable Model”. In our approach, we use 2D and 3D neural networks to recover the 3D position information of the cable from the input image, then adjust this 3D position information to increase it's accuracy, and finally create the “simulatable cable model” in Unity3D. The “Simulatable Cable Model” provides a new way to manipulate the cables, that is, to simulate the actions in the virtual environment and then apply it in the real world. Such a method can be used not only to support people daily life with robots, but also can be used to arrange cables in the workplace like factories and so on. We believe that our research is applicable and helpful to the recognition and manipulation of all cord-like objects, and will also be useful in the field of recognizing and manipulating soft objects.

Then, a more effec- tive topic-based extractive summarization is possible by using Latent Dirichlet Allocation (LDA) is demonstrated.
Impact of the COVID-19 pandemic on the digitalization and strategic development of German universities
Authors: Lübcke Maren , Bosse Elke , Book Astrid , Wannemacher Klaus , Gilch Harald
Published: September 2022

The HIS-Institute of Higher Education Development (HIS-HE) conducted a nationwide survey among Higher Education leaders about the extent to which the push for digitalization at German higher education institutions related to the COVID-19 pandemic has promoted strategic engagement with digitalization and how such experiences have been integrated into concepts for the future of teaching and learning. The findings show that the effects of the pandemic are most evident in the digitalization of teaching formats, while many infrastructural and technical developments had already been initiated before the pandemic and were at most accelerated.

When the COVID-19-related developments of digitalization are analyzed with regard to structural characteristics of the HEIs represented in the sample, it becomes apparent that there are no fundamental differences between universities and universities of applied sciences. Only the universities of arts and music are distinguished by the fact that the pandemic-related changes are generally smaller and fewer innovations are to be expected after the pandemic.

The range of disciplines of the HEIs also proves to be relevant when comparing HEIs with and without STEM subjects, as the former group shows a significantly greater dynamic of change.

Last but not least, differences can also be found with regard to the existence of a digitalization strategy. Universities with a digitalization strategy not only have a head start in terms of experience, since they already offered online teaching or hybrid formats before the pandemic. Rather, they have changed their teaching and examination formats particularly extensively in the course of the pandemic and are planning to a greater extent to use instruments and formats for digital teaching in the future.
Using Label Information in a Genetic Programming Based Method for Acquiring Tag Tree Patterns with Vertex Labels and Wildcards

Published: September 2022

Machine learning and data mining from tree structured data are studied intensively. In this paper, as tree structured patterns we use tag tree patterns with vertex and edge labels and wildcards in order to represent label connecting relation of vertices and edges in tree structured data. We propose an evolutionary learning method based on Genetic Programming for acquiring characteristic tag tree patterns with vertex and edge labels and wildcards from positive and negative tree structured data. By using label information, that is, label connecting relation of positive examples, as inappropriate individuals we can exclude tag tree patterns that do not satisfy label connecting relation of positive examples. We report experimental results on our evolutionary learning method and show the effectiveness of using label connecting relation of positive examples.
Seismic and lithological near surface characteristics of an area in north-east Colombia

Published: September 2022

The seismic image of deep rock, interesting for the petroleum industry, can be distorted by the heterogeneous near-surface layers, characterized by low wave propagation velocity. The conventional methods used in counteracting this effect seem less effective in complex areas with rough topography such asthose commonly found in Colombia, which are also affected by stronger tropical weathering. Characterizationof the near-surface layer was conducted in this work with the purpose to investigate these relationships. Geological and geophysical methods were applied using data from a 2D seismic survey performed in the Catatumbo area of Colombia and seismic data and cutting samples analysis from a couple of 60 m depth wells (downhole surveys), drilled at rough surface locations. Wave propagation velocities were calculated by the application of tomography and refraction. Visual and laboratory assays such as granulometry and mineralogy were used in the analysis of the cutting samples. It was then possible to relate physical and lithological characteristics with properties of seismic response. Differences between the seismic response and the geological description were also observed and some uncertainties were identified.

Published: September 2022

The process of crude distillation impacts the economy of any refinery in a considerable manner. Therefore, it is necessary to improve it taking good advantage of the available infrastructure, generating products that conform to the specifications without violating the equipment operating constraints or plant restrictions at industrial units. The objective of this paper is to present the development of an optimization model for a Crude Distillation Unit (CDU) system at a ECOPETROL S.A. refinery in Barrancabermeja, involving the typical restrictions (flow according to pipeline capacity, pumps, distillation columns, etc) and a restriction that has not been included in bibliographic reports for this type of models: the heat integration of streams from Atmospheric Distillation Towers (ADTs) and Vacuum Distillation Towers (VDT) with the heat exchanger networks for crude pre-heating. On the other hand, ADTs were modeled with Metamodels in function of column temperatures and pressures, pumparounds flows and return temperatures, stripping steam flows, Jet EBP ASTM D-86 and Diesel EBP ASTM D-86. Pre-heating trains were modeled with mass and energy balances, and design equation of each heat exchanger. The optimization model is NLP, maximizing the system profit. This model was implemented in GAMSide 22,2 using the CONOPT solver and it found new operating points with better economic results than those obtained with the normal operation in the real plants. It predicted optimum operation conditions of 3 ADTs for constant composition crude and calculated the yields and properties of atmospheric products, additional to temperatures and duties of 27 Crude Oil exchangers.

Published: September 2022

This paper introduces a new tank design for dehydrating and desalting large volumes of crude oils previously degasified, crude oil dehydration efficiency is reduced by gas presence in the emulsion interphase. The design presented in this paper is versatile (it is adaptable to any classical dehydration process), highly efficient in terms of separation (values usually greater than 90% and/or treated crude oil BSW less than 0,5% are ensured), low installation and operation costs, less consumption of additives. These are some of the advantages found in pilot tests plants and proven in industrial systems at the Ecopetrol S.A. production fields with treatment capacities from 14 to 50 KBD. Although this process also can be applied to other ranks of flow, maintaining the design critical conditions of each case in particular.  This system does not exhibit the typical limitations shown by treatment tradicional systems (FWKO, Gun Barrel, thermal and electrostatic separators, etc.) (Al-Ghamdi, 2007) since it can be easily adapted to system treatments for light, intermediate, and heavy crude oils and to treatments with BSW content ranging from a very low levels of < 1% to very high levels > 95%, values that are not unusual in production fields nowadays, especially where accelerated production methods are used.

A foreland basin is a dynamic system whose depositional systems migrate in response to changes in tectonic uplift patterns, sedimentary filling processes and isostatic rebound of the lithosphere. The Paleocene-middle Miocene foreland system of the Llanos foothills and Llanos basin of Colombia includes regional unconformities, abrupt changes in lithology/stacking patterns and flooding surfaces bounding reservoir and seal units. Here we integrate a systematic biostratigraphic study, stratal architecture and tectonic subsidence analyses, regional seismic profiles, and provenance data to define the diachronism of such surfaces and to document the direction of migration of foreland depozones.  In a flexurally-deformed basin, sandstone composition, rates of accommodation and sediment supply vary across and along the basin. We show how a coeval depositional profile in the Llanos foothills-Llanos foreland basin consists of litharenites interbedded with mudstones (seal rock, supplied from the orogenic front to the west) that correlate cratonward with organic-rich mudstones and coal (source rock), and to amalgamated fluvial-estuarine quartzarenites (reservoir rock, supplied from the craton to the east) adjacent to a subaerial forebulge (unconformity). This system migrated northward and eastward during the Paleocene, westward during the early-middle Eocene, and eastward during the Oligocene. In the lower-middle Miocene succession of the Llanos basin, identification of flooding events indicates a westward encroaching of a shallow-water lacustrine system that covered an eastward-directed fluvial-deltaic system. A similar process has been documented in other basins in Venezuela and Bolivia, indicating the regional extent of such flooding event may be related to the onset of Andean-scale mountain-building processes.

The gas flow equation is normally linearized to allow the liquid solution of the diffusivity equation to satisfy gas behavior when analyzing transient test data of gas reservoirs. When wellbore storage conditions are insignificant, drawdown tests are best analyzed using the pseudopressure function. On the other hand, buildup pressure tests require linearization of both pseudotime and pseudopressure. It is not the case for the TDS technique which is indifferently applied to either drawdown or buildup tests. However, whichever the case, pseudotime has certain effect at very long testing times in formations of moderate to high permeability.  In this paper, we implemented the Tiab’s Direct Synthesis (TDS) technique, to include pseudotime effects, and observe its influence on the interpretation results of gas well test data at early and late time periods. New analytical equations to estimate reservoir permeability, wellbore storage coefficient, pseudoskin factor and reservoir drainage area are presented. Then, a comparison of results against rigorous time was carried out for simulated and field cases. We found acceptable results for permeability, pseudoskin factor and wellbore storage coefficient. However, for the case of reservoir drainage area, the deviation error was of 4,1% for a simulated case and 17,9% for a field case. However, the smaller of these deviations may be small if related to pressure transient analysis results. However, this deviation in a gas reservoir with reserves of one tera standard cubic feet is equivalent to a huge difference of 38 gigas of standard cubic feet of gas which may have an economic impact to any oil company.
A COMPLEMENTARY CONVENTIONAL ANALYSIS FOR CHANNELIZED RESERVOIRS
Authors: Escobar Freddy Humberto , Montealegre M Matilde
Published: September 2022

Many well pressure data coming from long and narrow reservoirs which result from either fluvial deposition of faulting cannot be completely interpreted by conventional analysis since some flow regimes are not conventionally recognized yet in the oil literature. This narrow geometry allows for the simultaneous development of two linear flow regimes coming from each one of the lateral sides of the system towards the well. This has been called dual linear flow regime. If the well is off-centered with regards to the two lateral boundaries, then, one of the linear flow regimes vanishes and, then, two possibilities can be presented. Firstly, if the closer lateral boundary is close to flow the unique linear flow persists along the longer lateral boundary. It has been called single linear flow. Following this, either steady or pseudosteady states will develop. Secondly, if a constant-pressure closer lateral boundary is dealt with, then parabolic flow develops along the longer lateral boundary. Steady state has to be developed once the disturbance reaches the farther boundary. This study presents new equations for conventional analysis for the dual linear, linear and parabolic flow regimes recently introduced to the oil literature. The equations were validated by applying them to field and simulated examples.

Introduction

Gliomatosis peritonei (GP) is characterized by the presence of benign, mature glial implants in the peritoneum or omentum.

Aim

Understanding unusual findings with clear knowledge of pathological comparisons makes diagnosis more reliable and guides future treatment.

Case study

This is a case of a 70-years-old lady, post-menopausal, who presented with abdominal mass which progressively increased in size for the past 40 years. She also had constipation requiring laxatives and occasional lower abdominal pain. Her abdomen was clinically distended with a large hard central mass.

Results and discussion

Computed tomography of the abdomen showed features of left ovarian teratoma with multiple gliomatosis peritonei. Histopathology of the mass post-surgery revealed a left ovarian mature cystic teratoma and the peritoneal deposits to be heavily calcified and fibrotic mature implants with no evidence of malignancy.

Conclusions

Gliomatosis peritonei (GP) is a rare finding associated with ovarian teratoma and rare in postmenopausal women. It is important to appreciate a variety of radiological presentations of this condition to establish an accurate diagnosis.

The use of ultra-high performance concretes (UHPC) in the modern construction industry is increasingly widespread. UHPCs are a type of concrete that provides advantages in solving many engineering problems. UHPCs have superior properties compared to conventional concretes in terms of workability, self-settling, as well as high strength and durability. However, although UHPCs have many advantages, achieving the desired workability is one of the biggest challenges of the production procedure, since they contain high amounts of powder materials. Therefore, the aim of this study is to determine the most suitable superplasticizer (SP) additive in terms of workability and strength by using different SP additives in UHPC mixtures. In this study, workability and strength parameters were tested on UHPC mixtures using 8 different SP additives. First of all, the spreading diameters of the obtained mixtures were measured. For each mixture, compressive strength, density, ultrasound velocity, Schmidt hammer rebound and Leeb hardness measurements were performed on 70x140 mm sized cylindrical samples taken on days 2, 7 and 28. Since SPs have a working principle at the interfaces of particles in the internal structure of concrete, different behaviors were observed on workability, even if a little. All the results obtained have been compared with the literature and it has been proven that they meet the UHPC specifications.

The aim of this research is to analyze how Turkey’s Regulation on Fire Protection influence fire safety precautions on housing design and construction in Turkey. Tokat province center, which is one of the less populated cities of the country, has been chosen as the study area. In the study; 5 residential buildings which were designed and built before 2002 in when the Regulation entered into force and also 5 different residential buildings which were designed and built after 2002 have been analyzed comparatively according to 20 measurable criteria which are chosen among the provisions of the National Fire Regulations and according to the architectural project, the studies done in the building site and interviews carried out with responsible persons. The influence of Regulation on Protection of Buildings from Fire in the design and construction process of residential buildings constructed in Tokat has been evaluated with respect to the results of this analysis. When the results of analysis are examined, it has been determined that there has been an improvement, in terms of fire safety, in the houses which were designed after the national fire regulation entered into force but it has not reached to the desired level. The housings which are selected in this research are built after the regulation and they are among the high building group. It is thought that this situation makes it difficult to fulfill the provisions of the regulation, and therefore a number of criteria are not fulfilled.
