Con el avance de la Geodesia y la mejora de las especificaciones técnicas de los receptores de bajo costo, los GNSS abren nuevas alternativas para investigar las capacidades técnicas y rendimiento real que proveen este tipo de receptores para diferentes propósitos geodésicos. En este contexto, la precisión alcanzable fue analizada usando el receptor de bajo costo GNSS ZED-F9P en conjunto con dos antenas de orden geodésico (ASH701975.01B y LEIAS10 NONE) y una antena de bajo costo (BEIBT300 NONE). Las observaciones GNSS fueron llevadas a cabo en un periodo de dos días para cada modelo de antena. El análisis fue realizado en tiempos de observación de 12, 6 y 1 h, respectivamente. Estas observaciones fueron procesadas usando el método relativo estático mediante la inclusión de una estación de referencia continua del Instituto Nacional de Estadística y Geografía, la cual está localizada a una distancia aproximada de 4 km. Los resultados demuestran que la mayor precisión es lograda en un periodo de 12 h, con diferencias mínimas de 3 cm para la componente Norte y 33 cm para la vertical. En este sentido, la solución menos precisa es obtenida en el periodo de 1 h resultando diferencias de 70 cm, 46 cm y 2.3 m para la componente Norte, Este y vertical respectivamente.

With advancements in geodesy and enhancements in the technical specifications of low-cost receivers, GNSS opens up new avenues for investigating the capabilities and performance provided by these receivers for various geodetic purposes. In this context, the precision achievable using the low-cost GNSS receiver ZED-F9P in conjunction with two geodetic antennas (ASH701975.01B and LEIAS10 NONE) and a low-cost antenna (BEIBT300 NONE) was analyzed. GNSS observations were conducted over a 2-day period for each antenna model. The analysis involved observation durations of 12, 6, and 1 h. These observations were processed using the static relative method alongside a continuously operating GNSS station from the Active National Geodetic Network of the National Institute of Statistics and Geography, situated at ~4 km. The results demonstrate that the highest precision was achieved over a 12 h period, with minimal differences of 3 cm for the North component and 33 cm for the vertical component. Conversely, the least accurate solution was obtained within a 1 h observation period, resulting in differences of up to 70 cm, 46 cm, and 2.3 m for the North, East, and vertical components, respectively.

Authors: TAŞCI Halil İbrahim , KARAGÜLLE Erdal , TURK Emin 
Published: March 2024

Colonoscopy-related colonic perforation may occur through pneumatic or mechanical impact, or due to various therapeutic procedures. Mucosal herniation may also develop because of the increase in post-air insufflation pressure. This condition may render the mucosa air-permeable without a distinct focal perforation point.
A 63-year-old female patient, who had had surgery for malign rectal neoplasm five years before and followed-up for radiation proctitis, presented to the emergency department three days after she had control colonoscopy with complaints of a gradually deteriorating facial and cervical swelling along with respiratory distress that developed a day after the procedure. The results of the patient’s analyses revealed that she had colonoscopy-related pneumoperitoneum, pneumoretroperitoneum, pneumomediastinum, cervical and facial subcutaneous emphysema. Medical follow-up was planned for the patient since there were no signs of peritonitis in her physical examination, her overall condition was well, and because a long time had passed after the procedure. The patient was discharged after a two-day follow-up with no problems.
Colonoscopy-related intraperitoneal or extraperitoneal free air can both be seen immediately during the procedure and it can develop a long time after the procedure as well. Unnecessary surgical procedures can be prevented through medical follow-up under close monitoring in such patients particularly if they do not have peritonitis signs or symptoms and their overall condition is well.

Published: March 2024

Abstract
Different scales of fractures affect the reservoir quality in tight sandstone. There are more studies on macroscopic tectonic fractures but less on bedding fractures and microfractures. The control factors of multi-scale fractures are unclear. In this paper, we analyzed the types and controls of fractures in the second member of the Xinchang region in Western Sichuan. We use core and outcrops observations, imaging logging, scanning energy spectra, and rock slices. Natural fractures can be classified into tectonic, bedding, and microscopic types. The tectonic fractures are mainly low- to medium-angle tensile fractures. The bedding fractures are nearly horizontally distributed along the bedding surface, including parallel, dark mineral interface, and carbonaceous fragments interface bedding fractures. The microfractures develop intra-grain, edge-grain, and inter-grain types. The intra-grain microfractures are inside quartz or feldspar grains, whereas inter-grain types penetrate multiple grains with larger extension lengths. The tectonic fractures are related to the stress, grain size, mineral component, argillaceous content, and lithologic thickness. Parallel bedding fractures are controlled by the coupling of water depth and flow velocity. Bedding fractures at the interface are controlled by rock component. The microfractures are controlled by the length-width axis ratio of the grain, grain element content, and brittleness index. Fractures of different scales form a three-dimensional fracture system that has a substantial impact on the gas production.
Devon Energy and Software Partners Enable Automatic Bottomhole Pressure Calculations
Authors: Carlsen Mathias 
Published: March 2024

_
More than a decade ago, Devon Energy made it a priority to enhance its digital infrastructure which has led to a step change in internal data access along with how the company securely works with its third-party vendors.
Easy access to relevant, trustworthy, and value-adding data has become the norm, not the exception, for the US oil and gas producer’s subsurface engineering teams. The upside extends beyond mere convenience, however, and translates directly into faster decision making which is one of the keys to success in the dynamic landscape of unconventional developments.
When data is seamlessly connected for daily consumption, engineers engage with it regularly, integrating it into their daily workflows. Additionally, we see that the frequency of use is directly correlated with accessibility.
The emphasis on accessibility reflects Devon’s proactive efforts to treat its data more and more as a valuable asset. By democratizing data and analysis tools, business-impacting insights are more readily available to engineers and decision-makers throughout the organization.
This case study outlines one of the most recent and tangible outcomes of this collaborative philosophy: automatic calculation of bottomhole pressure (BHP).

Solving for Bottomhole Pressures
As shown in Fig. 1, accurate and reliable flowing BHP data is a critical input for a number of important engineering applications in both conventional and unconventional settings: reservoir simulation, production diagnostics, nodal analysis, rate transient analysis, pressure transient analysis, and material balance.
The list goes on, but the overarching point is that BHP data allows engineers to make informed decisions, i.e., high-confidence estimations on future well production, reservoir management, and optimization strategies.
The rub is that acquiring accurate BHP measurements has historically been a luxury service that is too costly to scale up beyond a few science projects.
Operators that desire such critical data often turn to BHP gauges, which are positioned down in the wellbore to measure pressure at a specific depth. But given an average cost of $50,000 per installation, it is estimated that less than 5% of all horizontal wells drilled during the North American shale revolution have benefited from the use of downhole gauges.
Without a downhole gauge, operators must calculate the pressures from surface pressure. The problem here is again one of scale. Using surface pressure has traditionally required the manual gathering of the proper data sets and calculating BHP.
From there, the process is not only time consuming but considered to be error prone. Applying any of the published methods may take a reasonably experienced engineer half an hour to complete a BHP calculation and the odds of a miscalculation rise as the data set grows in size and complexity.

This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper OTC 32671, “Technical Evaluation of the Use of Hybrid Energy (Solar and Offshore Wind) To Supply Artificial Lift Pumps on an Oil Platform on the Equatorial Margin,” by W.K. Silva, Ana L.R. Cunha, SPE, and Ana C. Alves, Federal University of Pará, et al. The paper has not been peer reviewed.

_
The complete paper investigates the relevance of wind and solar energy for the supply of artificial lift systems on offshore platforms in the Brazilian equatorial region. The scope of the authors’ study encompassed a detailed technical and environmental assessment, with an emphasis on the integration of a 10-MW floating solar photovoltaic (FSPV) power system to meet demand for 10 pumps. The results obtained highlight the high viability of the system in meeting the demand of these pumps and ensuring an adequate and sustainable energy supply.

Area of Study
The equatorial margin is an area in northern Brazil covering part of the sedimentary basins of the equatorial Atlantic. The region is home to important sedimentary basins such as the Amazon Basin, the Pará-Maranhão Basin, the Barreirinhas Basin, the Potiguar Basin, and the Ceará Basin, all known for their hydrocarbon reserves.
Offshore oil-exploration activities in the equatorial margin involve the installation of drilling and production platforms that include artificial lift systems. To power these systems, a reliable and continuous power source is required. The use of green energies such as wind and solar can be advantageous in meeting this purpose.
For the present study, the coastal city of Salinópolis in the state of Pará was selected because of its plentiful meteorological data and its location in the Pará-Maranhão Basin region.

Methodology
The methodology of the work consists of the evaluation of the energy required for artificial lifting systems with 10 pumps, using the nine steps developed by Baker Hughes’ Artificial Lift Research and Technology Center for the calculation of the power required to drive the pumps. Additionally, the study uses the System Advisor Model (SAM), November 2022 version, developed by the National Renewable Energy Laboratory to simulate the FSPV. Information related to wind potential was obtained through the measuring stations of the National Institute of Meteorology (INMET).

Authors: Kim Sung Hyun , Kim Chung Reen , Park Donghwi , Cho Kang Hee , Nam Je Shik 
Published: March 2024

Abstract
Background
Sleep has been known to affect childhood development. Sleep disturbance is likely to be more common in children with developmental delay (DD) than in children with normal development. There are few studies on the correlation between sleep disturbance and developmental aspects in children with DD. Therefore, this study aimed to evaluate the associations between the two in children with DD.
Methods
A total of 45 children (age range 27.0 ± 11.1) with DD were recruited and evaluated using sleep disturbance scale for children (SDSC), Bayley scales of infant and toddler development (BSID)-Ⅲ, gross-motor function measure (GMFM), and functional independence measure (FIM). The outcomes are expressed as means and standard deviations. The correlation between SDSC and BSID-Ⅲ, GMFM, and FIM was assessed using Spearman’s rank correlation test. Multiple regression analysis was performed to investigate the relationship between BSID-Ⅲ and SDSC. Statistical significance was set at p < 0.05.
Results
In multiple regression analysis, cognition and socio-emotional domains of BSID-III were significantly associated with DOES subscore in SDSC. In addition, expressive language domain of the BSID-III was found to be associated with DA subscore in SDSC.
Conclusion
This study demonstrated that DA and DOES subscore of SDSC were correlated with developmental aspects in preschool-aged children with DD. This study suggest that we should pay more attention to sleep problems, even in preschool aged children with DD.

Abstract

The present study aimed at to evaluate the performance of integrated system composed of microalgae (MA) and constructed wetlands (CW). The MA production tank was set up as a raceway type and microalgae of the genus Chlorella were inoculated, while the CW was set up inspired by the first stage of the French model and vegetated with the macrophytes Chrysopogon zizanioides, Typha domingensis and Dracaena trifaciata. The Hydraulic Retention Time in each unit was of 7 days, totaling 14 days of treatment. Promising results were obtained regarding the reductions of dissolved organic carbon (67.2%) and Total N (68.6%). The treatment was also able to fully remove the acute ecotoxicity against Dapnhia magna and the genotoxicity in the A. cepa test assay. Chromatographic analysis showed the presence of 9 pharmaceuticals in the raw wastewaters, whereas after the CW unit only residuals of dipyrone (1%) were still detected. Future recommendations include the investigation of the main removal mechanisms of the pharmaceuticals and improvements of the separation process of the MA.

Authors: Sarvajith Manjunath , Reddy Gangidi Kiran Kumar , Nancharaiah Yarlagadda Venkata 
Published: March 2024

Abstract
Despite propionate being an important constituent of domestic wastewater, its effect on aerobic granular sludge (AGS) development and biological nutrient removal (BNR) pathways is not well studied. This study investigated the cultivation of AGS and establishment of BNR pathways using propionate as a sole carbon source in the bioreactors with and without granular activated carbon (GAC) particles. The presence of GAC particles reduced the start-up period for AGS formation and established of BNR pathways with propionate feeding. Aerobic granules were compact and had stable settling characteristics (≥ 1 mm, 6 g/L MLSS and 40 mL/g SVI). An increase in alginate-like exopolysaccharide (ALE) up to 400 mgALE/gSS corroborated with stable AGS formation. Stable and effective ammonium and total nitrogen removals were established by day 30. Ammonium was removed via simultaneous nitrification and denitrification as well as partial nitrification and denitritation pathways. Stable and efficient phosphorus removal was established from day 80. High phosphorus removals were corroborated with the abundance of polyphosphate accumulating organisms in the GAC biofilms. The GAC biofilms separated from the co-existing granules exhibited efficient phosphorus removal via enhanced bio-P removal. The high abundance of Thauera sp. in the GAC biofilms indicated its role in granulation and phosphorus removal under propionate feeding conditions.

Published: March 2024

Abstract

Fourier transform infrared (FTIR) analysis is robust technique which can be used to identify functional groups of given material. In the present study an attempt was made to profile the cestode powder of Relliantina tetragona for the first time. The study was quite successful and FTIR analysis of the cestode powder yielded interesting results. The spectrum ranged from 1000-3500cm-1.A total of 19 major peaks were identified, of which five were the sharp peaks. The highest sharp peak was found at 1539cm-1, followed by 1641cm-1, 1026cm-1, 2920cm-1 and 2851cm-1.The functional groups were identified using https://chem.libretexts.org/ and Thermo fisher databases. The identification and interpretation of these peaks, yielded interesting results. The highest peak at 1539, refers to alpha (α) elastin, which seems to be abundant in the sample and probably justifies with the fact that the parasite may be often dependent upon this protein for apolysis. Peak at 1641cm-1 suggest a strong c = c stretching and refers to the presence of amide group, similarly 1026cm-1 refers to cellulose, followed by 2920cm-1 for suberin and 2851cm-1 for lignin, indicating that the cestode may have ingested these plant components from the host animal (chicken) and accumulated in its body. Apart from these peaks some minor peaks were observed at 721cm-1 and also at 1081cm-1. The peak at 721cm-1 suggests accumulation of iron oxide hematite and the peak at 1081cm-1suggesting the presence of cadmium oxide. In summary it may be said that, functional group profiling of Relliatina tetragona using FTIR was successful in giving us an in-depth understanding about the composition of dead parasite and also about the dietary constituents of the host animal in particular, which might help us to develop newer strategies and drugs to control the helminthic infections.
