WstępSacharoza, nazywana popularnie przez konsumentów cukrem rafinowanym, jest substancją bezpośrednio kojarzącą się ze smakiem słodkim. Rynek dietetyczny oferuje jednak o wiele więcej źródeł tego smaku. Celem pracy było ustalenie, czy istnieje związek między poziomem wiedzy o substancjach słodzących a czynnikami takimi jak: miejsce zamieszkania, wykształcenie, płeć, wiek lub wskaźnik masy ciała (<i>body mass index</i> – BMI), a także zbadanie wiedzy ogólnej o substancjach słodzących i ustalenie, który ze słodzików jest najlepiej rozpoznawalny.Materiał i metodyBadanie przeprowadzono w pięciu laboratoriach „Dialab” na terenie Dolnego Śląska w miesiącach kwiecień–maj 2017 r. Dobór próby miał charakter losowy. W badaniu wzięły udział 132 osoby.WynikiW badanej populacji pacjentów tylko 15 osób wykazało, że cierpi na choroby dietozależne. Odpowiednio 87,9% pacjentów twierdziło, że odżywia się zdrowo. W grupie najlepiej rozpoznawalnych substancji słodzących znalazły się miód (73%), ksylitol (52%) i stewia (48%). Udowodniono również istotną korelację między BMI a poziomem wiedzy o substytutach cukru.WnioskiMiejsce zamieszkania, wykształcenie, wiek oraz płeć nie mają wpływu na świadomość żywieniową ankietowanych. Czynnikiem, który odgrywa w tym zakresie rolę, jest wysokie BMI. Próba ustalenia, czy choroby dietozależne mają istotny wpływ na zwiększanie poziomu wiedzy o substancjach słodzących, wymaga kontynuacji badań, gdyż spostrzeżenia wynikające z dotychczasowej obserwacji nie wystarczają, aby to potwierdzić. Poziom wiedzy na temat substancji słodzących badanych osób zaklasyfikowano jako akceptowalny.
Thai Undergraduate Student Awareness of Regular and Irregular Grapheme-Phoneme Correspondence
Authors: Perrodin David D. 
Published: November 2021

<p>Recent events in Thailand in reference to the teaching of phonics for better comprehension of English vocabulary have highlighted the overuse of identifying letter-sound relationships in English by utilizing the familiar Thai orthography to assist developing Thai EFL learners. This paper investigated the long-term effects of using such pedagogy on recognizing regular and irregular Grapheme-Phoneme Correspondences (GPC) in English by Thai undergraduate students. To address this matter, the study used a convenience sampling of 373 first-year university students from 11 general education English classes at a mid-sized private university near Bangkok, Thailand. The familiar English poem <em>I Take It You Already Know</em> was employed for data collection, for it consists of a practical ratio of frequent and infrequent English grapheme-phoneme correspondences. Extensive lists of recognized grapheme-phoneme correspondences were used to identify the frequent or regular, and the infrequent or irregular main phoneme present in each of the 60 most frequently queried content words of the poem. Point-Biserial Correlation was employed to measure the strength of association between the frequency occurrence of the most queried content words from the data set, and the examined weighted word frequency data. The findings suggest that, in general, the Thai undergraduate students demonstrated an overall lack of recognition of regular and irregular Grapheme-Phoneme Correspondences of English. </p>

El turismo cultural urbano tras la pandemia de la COVID-19: una perspectiva y propuestas de un modelo alternativo
El turismo era una máquina en continuo crecimiento hasta su paralización con la pandemia de la COVID-19. En las ciudades, se incrementaban sus impactos negativos y había situaciones de sobreturismo. La pandemia es un momento disruptivo y excepcional. Es una ocasión para abandonar el camino hacia la insostenibilidad. Este artículo es un análisis turístico crítico donde se plantea cuál es la perspectiva pospandémica del turismo cultural urbano con una visión alejada de la búsqueda del lucro como fin último. El objetivo principal es plantear propuestas de un modelo alternativo y sostenible. Es un trabajo teórico que recurre a la revisión literaria de 180 obras científicas. De manera complementaria, se accede a las informaciones de los medios y se realiza una observación de la realidad, con trabajo de campo. Se propone una limitación de los visitantes y una mejora en la calidad mediante visitas guiadas, rutas turísticas, turismo experiencial y turismo virtualizado. Y se plantea una nueva gobernanza turística centralizada y una regulación de los agentes privados. Se considera que el artículo es de interés para los responsables públicos del turismo en las ciudades.
Numerical Study on the Impact of Spiral Tortuous Hole on Cuttings Removal in Horizontal Wells

Published: November 2021

SummaryHorizontal wells are designed to have smooth (straight), curved, and lateral sections. However, the actual drilled path usually suffers from unwanted undulations from the planned well trajectory known as wellbore tortuosity. Wellbore tortuosity can slow the drilling penetration rate, aggravate drillstring vibration and buckling, complicate the casing and cement job, and lead to inaccurate wellbore position. This paper presents a validated computational fluid dynamics (CFD) model to investigate the impact of wellbore tortuosity on hole cleaning. The Eulerian-Eulerian approach is used to simulate solid-liquid laminar flow in annular geometry using polyhedral mesh. Then, the impact of wellbore tortuosity on cuttings accumulation, annular pressure loss, and fluid velocity was investigated and compared with the flow behavior in a straight horizontal well. A parametric analysis of spiral period length, spiral amplitude, drillstring rotation, flow rate, annular eccentricity, drilling rate of penetration (ROP), and cuttings size was conducted to assess their influence on cuttings transport in spiral tortuous holes and their relative magnitude to other design or operating factors.Simulation results show that polyhedral mesh is an optimum meshing technique for spiral profile geometry. Wellbore tortuosity aggravates hole cleaning in lateral sections based on the length of the spiral period and/or the spiral amplitude. Reduction in cuttings velocity was observed in the top part of the spiral geometry (crest), causing large deposition of cuttings in this area compared to the spiral lower part (trough). Drillstring rotation from 0 to 200 rev/min is the critical range for efficient hole cleaning in spiral geometry. Cuttings size can improve cuttings accumulation if the particle size is larger than the viscous layer located near the bed velocity profile. The drilling ROP and annular eccentricity aggravate cuttings accumulation and bed deposition in a spiral hole, similar to what is normally observed in straight horizontal wells.
Logging Optimization and Data Analysis Enabling Bypass Pay Identification and Hydrocarbon Quantification with Advanced Pulsed Neutron Behind Casing

Abstract
Ukraine ranks the third largest gas reserves in Europe. Gas production is carried out mainly from the Dnieper-Donets Basin (DDB). A gradual decline in reserves is forcing Ukraine to actively search for possible sources to increase reserves by finding bypassed gas intervals in existing wells or exploration of new prospects. This paper describes 3 case studies, where advanced pulsed neutron logging technology has shown exceptional value in gas-bearing layer identification in different scenarios.
The logging technology was applied for formation evaluation. The technology is based on the neutron interaction with the minerals and the fluids contained in the pore space. The logging tool combines measurements from multiple detectors and spacing for self-compensated neutron cross-capture section (sigma) and hydrogen index (HI), and the Fast Neutron Cross Section (FNXS) high-energy neutron elastic cross section rock property. Comprehensive capture and inelastic elemental spectroscopy are simultaneously recorded and processed to describe the elemental composition and the matrix properties, reducing the uncertainties related to drilling cuttings analysis, and overall, the petrophysical evaluation combined with other log outputs.
The proposed methodology was tested in several wells, both in open hole and behind casing. In the study we present its application in three wells from different fields of the DDB. The log data acquisition and analysis were performed across several sandstone beds and carbonates formation with low porosities (&lt;10%), in various combinations of casing and holes sizes. The results showed the robustness and effectiveness of using the advanced pulsed neutron logging (PNL) technologies in multiple cases:
Case Study A: Enabling a standalone cased hole evaluation and highlighting new potential reservoir zones otherwise overlooked due to absence of open hole logs. Case Study B: Finding by-passed hydrocarbon intervals that were missed from log analysis based on conventional open hole logs for current field operator. Case Study C: Identifying gas saturated reservoirs and providing solid lithology identification that previously was questioned from drilling cuttings in an unconventional reservoir.

Abstract
The objective of this paper is to demonstrate multiple application of multi-energy gamma ray venture type multiphase flowmeter (MPFM) trial campaign in Karachaganak gas condensate giant carbonate field, operated by KPO B.V.
The results of MPFM that was included into surface well test spread, to verify its performance, was compared against portable test separator and plant production testing facilities (control separator, flowmeters) and manual sampling results. MPFM from other vendors historically failed to deliver accurate production measurement mainly due to complexity of reservoir fluid in Karachaganak field. To ensure the MPFM considers this complexity, PVT samples were taken to provide laboratory data for PVT model of the MPFM to ensure sufficient quality of PVT data and compare against PVT model inside MPFM.
First application of MPFM was during clean-up of the well prior handover well to production. Using MPFM helped to improve the quality during data acquisition. This information was critical for the well to be accepted by processing facility it is hooked-up to and to define optimal operating regime. Validation of BS&W, GOR and rates in unstable (foaming, carry over) and transient phase of production using MPFM has shown practical advantages.
Another application was for water sampling loops to measure water cut and production rates. KPO has had challenges with inaccurate water cut measurement due to the limitations of existing test separators. A recent approach of performing fluid sampling (sampling loop) at the well head proved to be reliable source of measurements. In addition, the MPFM in combination with the test separator has been used to further improve the quality of the measurements of each phase.
The third MPFM application had been with high gas-volume-fraction (HGVF) pumps, that helped to produce from low reservoir pressure, low GOR and high water cut wells. The operational range of HGVF pump was limited to maximum 75-80% of gas-volume-fraction (GVF). MPFM measures GVF in real-time to ensure HGVF pump operates in optimum operational range by managing the surface flow conditions.
With current limitations of test separators in Karachaganak field and due to complexity of the gas-condensate fluid, the use of MPFM brings additional quality in the measurements (rates, water cut and GOR) which is crucial for field production optimization, reservoir management and short and long term forecasting.

Abstract
Processing of the seismic data acquired in areas of complex geology of the Dnieper-Donets basin, characterized by the salt tectonics, requires special attention to the salt dome interpretation. For this purpose, Kirchhoff Depth Imaging and Reverse Time Migration (RTM) were applied and compared. This is the first such experience in the Dnieper-Donets basin. According to international experience, RTM is the most accurate seismic imaging method for steep and vertical geological (acoustic contrast) boundaries. Application of the RTM on 3D WAZ land data is a great challenge in Dnieper-Donets Basin because of the poor quality of the data with a low signal-to-noise ratio and irregular spatial sampling due to seismic acquisition gaps and missing traces. The RTM algorithm requires data, organized to native positions of seismic shots. For KPSDM we used regularized data after 5D interpolation. This affects the result for near salt reflection. The analysis of KPSDM and RTM results for the two areas revealed the same features. RTM seismic data looked more smoothed, but for steeply dipping reflections, lateral continuity of reflections was much improved. The upper part (1000 m) of the RTM has shadow zones caused by low fold. Other differences between Kirchhoff data and RTM are in the spectral content, as the former is characterized by the full range of seismic frequency spectrum. Conversely, beneath the salt, the RTM has reflections with steep dips which are not observed on the KPSDM. It is possible to identify new prospects using the RTM seismic image. Reverse Time Migration of 3D seismic data has shown geologically consistent results and has the potential to identify undiscovered hydrocarbon traps and to improve salt flank delineation in the complex geology of the Dnieper-Donets Basin's salt domes.

Abstract
The offshore segments of the Pre-Dobrogea foredeep is absolutely unexplored, there is no a single well penetrated Paleozoic units within offshore areas. This study, a deep dive into petroleum system evolution of similar foredeep basin based on a 3D basin modeling was performed in order to get understanding of petroleum systems and geology of offshore segment of Pre-Dobrogea. Western edge of East European craton is about 1450 km takes from Western Black sea shore to Southern shore of Baltic sea. This area within Ukraine includes Pre-Dobrogea foredeep basin, Pre-Carpathian foredeep basin (Bylche-Volytsa foredeep), Lviv Paleozoic basin and extensive Paleozoic margin called Volyno-Podillia area (Figure 1). All mentioned basins have similar sedimentary history, similar dynamics of tectonic evolution, proven petroleum systems of almost the same age, discovered commercial and sub-commercial accumulations and are heavily underexplored and undervalued. 3D basin modeling as a primary exploration technique was applied to mentioned basins in order to identify common features in tectonic development, in sedimentation and evolution of petroleum systems. Identified basins’ similar features now could be extrapolated to underexplored formations and areas within the study area.

Nano Chemical Design for Excessive Water Production Control in Taq Taq Oil Field
Authors: Soka Sakar , Sidiq Hiwa 
Published: November 2021

Abstract
A common problem in oil and gas field is premature and excessive water production through higher permeable thief zone, faults, water conning or channeling and natural or induced fracture. Excessive water production impacts the economics of a well through increasing rate of corrosion, emulsion and scale formation, consequently shortening its production life and lowering flowing wellhead pressure. There are several techniques used to control excessive water production such as chemical and mechanical.
In this work a novel chemical approach was followed to tackle excessive water production in Taq Taq oil field located in Kurdistan Region Iraq. Water production into the reservoir was determined to be through the fractures as the reservoir units are highly fractured carbonates. Therefore, the chemicals designed by this work were to reduce excessive water production selectively and fracture connectivity in the zones where excessive water production is expected.
Three nano-solutions have been prepared and investigated for their rheological properties. Only one is selected and met the field screening criteria. The composition of the nano-solutions were mainly polyacrylamide mixed with nano composite of cement, clay and inorganic cross-linker. All nano-solution underwent extensive screening and studied for their mechanical strength, toughness and tensile module. Results showed that nano-solutions strength increases with increasing the nano concentration. Similarly, their viscosity and degradation resistance are improved noticeably with nano composites.
The scanning Electron Microscopy (SEM) was also used to characterized the nano size and distribution studied by this work.

Abstract
The newly identified coronavirus SARS-CoV-2 is responsible for the worldwide pandemic COVID-19. Considerable efforts have been made for the development of effective vaccine strategies against COVID-19. The SARS-CoV-2 spike protein has been assigned as major antigen candidate for the development of COVID-19 vaccines. The COVID-19 mRNA BNT162b2 vaccine (comirnaty, Pfizer/BioNTech) is a lipid nanoparticle-encapsulated mRNA encoding a full-length and prefusion-stabilized SARS-CoV-2 spike protein. In the present study, synthetic peptide-based ELISA assays were performed to identify linear B cell epitopes that contribute to elicitation of antibody response in vaccinated individuals with comirnaty. The synthetic S2P6 peptide containing the spike residues 1138/1169 and to a lesser extent, the synthetic S1P4 peptide containing the spike residues 616/644 were recognized by the immune sera from comirnaty recipients but not COVID-19 recovered patients. The S2P6 peptide has been identified as immunogenic peptide in adult BALB/c mice that received protein-peptide conjugates in a prime-boost schedule. Based on our data, we propose that the synthetic S2P6 peptide and to a lesser extent the synthetic S1P4 peptide, would be of interest to measure the dynamic of antibody response to comirnaty vaccine. The synthetic S2P6 peptide is a SARS-CoV-2 spike peptide candidate for the development of peptide-based vaccines against COVID-19.
Microscopic mechanism for fluctuating pair density wave

Published: November 2021

Abstract
In weakly coupled BCS superconductors, only electrons within a tiny energy window around the Fermi energy, EF, form Cooper pairs. This may not be the case in strong coupling superconductors such as cuprates, FeSe, SrTiO3 or cold atom condensates where the pairing scale, EB, becomes comparable or even larger than EF. In cuprates, for example, a plausible candidate for the pseudogap state at low doping is a fluctuating pair density wave, but no microscopic model has yet been found which supports such a state. In this work, we write an analytically solvable model to examine pairing phases in the strongly coupled regime and in the presence of anisotropic interactions. Already for moderate coupling we find an unusual finite temperature phase, below an instability temperature Ti, where local pair correlations have non-zero center-of-mass momentum but lack long-range order. At low temperature, this fluctuating pair density wave can condense either to a uniform d-wave super- conductor or the widely postulated pair-density wave phase depending on the interaction strength. Our minimal model offers a unified microscopic framework to understand the emergence of both fluctuating and long range pair density waves in realistic systems.
