Objectives: Glycemia management in critical care is posing a challenge in frequent measuring and adequate insulin dose adjustment. In recent years continuous glucose measurement is gaining accuracy and reliability in outpatient and inpatient setting. The aim of this study was to assess the feasibility and accuracy of real-time continuous glucose monitoring in ICU patients after major abdominal surgery.

Research design and methods: We included patients undergoing pancreatic surgery and solid organ transplantation (liver, pancreas, islets of Langerhans, kidney) requiring ICU stay after surgery. We used a Dexcom G6 sensor, placed in the infraclavicular region, for rtCGM. Arterial blood glucose measured by the amperometric principle (ABL 800, Radiometer, Copenhagen, Denmark) served as reference values and for calibration. Blood glucose was also routinely monitored by StatStrip bedside glucose meter. Sensor accuracy was assessed by mean absolute relative difference (MARD), bias, modified Bland-Altman plot and Surveillance Error Grid for paired samples of glucose values from CGM and ABL.

Results: We analyzed data from 61 patients and obtained 1546 paired glucose values from CGM and ABL. Active sensor use was 95.1%. MARD was 9.4%, relative bias 1,4%, 92.8% values fell in zone A, 6.1% in zone B and 1.2% in zone C of Surveillance Error Grid. Median time in range was 78%, with minimum (<1%) time spent in hypoglycemia. StatStrip glucose meter MARD compared to ABL was 5.8%.

Conclusions: Our study shows clinically applicable accuracy and reliability of Dexcom G6 CGM in postoperative ICU patients and a feasible alternative sensor placement site.

Published: February 2024

Objective: To explore 24-hour post-exercise glycemia and hypoglycemia risk, data from the Type 1 Diabetes Exercise Initiative Pediatric (T1DEXIP) study were analyzed to examine factors that may influence glycemia. Research Design and Methods: Real-world observational study with participant self-reported physical activity, food intake, and insulin dosing (multiple daily injection users). Heart rate, continuous glucose data, and available pump data were collected. Results: 251 adolescents (age=14±2 years [mean±SD]; HbA1c=7.1±1.3% (54±14.2mmol/mol); 42% female) recorded 3,319 activities over ~10 days. Trends for lower mean glucose post-exercise were observed in those with shorter disease duration and lower hemoglobin HbA1c; no difference by insulin delivery modality was identified. Larger glucose drops during exercise were associated with lower post-exercise mean glucose levels, immediately after activity (P<0.001) and 12-<16 hours later (P=0.02). Hypoglycemia occurred on 14% of nights following exercise vs. 12% after sedentary days. On nights following exercise, more hypoglycemia occurred when average total activity was ≥60 min/day (17% vs. 8% of nights, P=0.01) and on days with longer individual exercise sessions. Higher nocturnal hypoglycemia rates were also observed in those with longer disease duration, lower HbA1c, conventional pump use and if time below range was >4% in the previous 24hrs. Conclusions: In this large real-world pediatric exercise study, nocturnal hypoglycemia was higher on nights when average activity duration was higher. Characterizing both participant and event-level factors that impact glucose in the post-exercise recovery period may support development of new guidelines, decision support-tools and refine insulin delivery algorithms to better support exercise in youth with diabetes.

Published: February 2024

This work aimed to apply a simple method to evaluate the effect of anticancer drugs’ treatment on in vitro models of cancer cells by laser biospeckle pattern measurements. Thus, the study is concerned with the detection of reduced dosage required for targeting tumors by drug combination encapsulated in liposomal nanoparticles using biospeckle measurements. The curcumin drug encapsulated in liposomal nanoparticles was applied to target the MCF-7 breast cancer cells and HepG2 liver cancer cells on slides as biospecimens with different concentrations for both cancer cell models, separately. For each cancer cell model under treatment, a simple way is to access this information, as the surfaces of biosample were illuminated by a coherent laser beam of green wavelengths of 532.0 nm with output power < 50 mW. The random interference effects were produced, which are known as biospeckle patterns. These speckle patterns were imaged for biosamples of the cancer cells under test treatment for each liposomal drug concentration, digitally. Then, laser biospeckle contrast measurements were used along with an image processing program to detect the change in speckle patterns due to the change in cancer cell size, cancer cell density, and bioavailability, which correlated to the various liposomal curcumin concentrations. First, the obtained results emphasized that the polydispersity index has an acceptable value lower than 0.7 for the effective clinical applications of the used nanocarrier liposome formulations presented in this study. Second, the study pointed to the laser biospeckle technique as a useful method to evaluate intensity and contrast measurements, which correspond to a safe use of the liposomal curcumin drug at a suitable concentration and an acceptable cytotoxicity.

Authors: Guo Meng , Yang Yule , Yang Chao , Dai Donghua
Published: February 2024

The study aims to explore the impact of structural parameters on the formability, mechanical properties, and heat conductivity of body centered cubic (BCC) lattice structures produced through laser powder bed fusion (LPBF). The BCC lattice structures with varied cell diameters and cell sizes were fabricated using LPBF. Surface morphologies, compression properties, and numerical simulation of heat transfer were carried out. Results indicated that the relative density of the BCC structure was influenced by the diameter and size of the cell. An increase in the diameter or a decrease in the size of the cell led to an increase in the relative density of the BCC lattice structure. However, the surface forming quality decreased. On the other hand, the compressive strength of the structure increased, and the heat transfer property was also enhanced. The BCC lattice structure achieved its highest relative density and obtained a peak compressive strength of 320.66 MPa when the cell rod diameter was 1.5 mm and the cell size was 3 mm.

conducción política en el Informe de la Comisión de Análisis y Evaluación de las Responsabilidades en el Conflicto del Atlántico Sur (CAERCAS)
Authors: Chao Luis Daniel
Published: February 2024

Este artículo analiza el Informe de la Comisión de Análisis y Evaluación de las Responsabilidades en el Conflicto del Atlántico Sur (conocido como Informe Rattenbach), enfocándose en la evaluación de la conducción política. El trabajo parte de preguntarse qué cuestión política se evaluó y cómo, y, a la vez, qué sostuvo la determinación del carácter secreto asignado al Informe en 1983. 
En primer lugar, se ubica el escenario genésico del trabajo de la CAERCAS para poder comprender los argumentos que llevaron a buscar respuestas militares y políticas a la guerra. Luego, se analiza el informe prestando atención a las declaraciones, tipos de preguntas, evaluación y asignación de responsabilidades. Finalmente, se reflexiona sobre las distancias entre este y otros informes que evaluaron la guerra producidos por las FF. AA. —especialmente por el Ejército—, mostrando las diferencias fundamentales con el producido por la CAERCAS. Con este estudio se procura pensar el lugar de la Guerra de Malvinas en el proceso de transición democrática en la Argentina.
Construction of model contract law for Guangdong-Macao intensive cooperation zone in Hengqin
Authors: Iong Man Teng
Published: February 2024

The Guangdong-Macao Intensive Cooperation Zone in Hengqin (Intensive Cooperation Zone) has emerged as a pivotal economic hub, attracting Macao residents and enterprises. However, disparities in contract-related rules between the zone and Macao have led to legal challenges. This article delves into a comparative study of contract laws between the People’s Republic of China (PRC) and Macao. Analyzing key facets such as pacta sunt servanda, freedom of contract, principle of equity, contract form, principles of interpretation, and termination of contract, the study identifies nuanced differences. Recognizing the imperative of aligning contract laws for the Intensive Cooperation Zone’s development, the article advocates for a unified legal environment. To achieve this, the author proposes a model contract law that prioritises the United Nations Convention on Contracts for the International Sale of Goods (CISG) as the basis. Notably, Macao’s contract-related rules should govern aspects not covered by the CISG given the policy trend in the Intensive Cooperation Zone. The proposed model law serves as a foundation for legislative reform, aiming to address the existing disparities and promote the Intensive Cooperation Zone’s economic growth.

Published: February 2024

Medical applications of additive manufacturing have seen a significant growth in recent years due to availability of advanced medical imaging and design software and wide range of materials. The range of additively manufactured medical implants is growing rapidly and surgeons need to keep themselves updated with state-of-the-art of the technology. This article reviews several articles related to medical implants to help surgeons and researchers to stay up-to-date on recent developments in the domain. Additively manufactured medical implants are reviewed into five categories: orthopedic implants, dental implants, cranioplasty implants, scaffold implants for tissue engineering and other medical implants including chest wall reconstructive implants, anti-migration enhanced tracheal stents, and buccopharyngeal stents. Additive manufacturing process and material for fabrication of each type of implant are highlighted in the study. It has been observed that titanium alloy is a suitable material for cementless arthroplasty. Porosity in the implants supports bone ingrowth, which results in a significant reduction in stress shielding. Additive manufacturing has a very attractive future in medical implant fabrication due to its capability to produce complex and customized implants. The AM provides freedom to researcher to explore the complex design of medical implants for better bone regeneration and improved osseointegration.

The article deals with the representation of the colour bilyi (white) in the idiolect of the prominent Ukrainian writer Vasyl Stefanyk. His peculiar writing manner has been the subject of numerous studies since the publication of his first short stories. Although most of these studies did not encompass the full collection of his literary works, with a lot of them being edited during Soviet times. Therefore, the research complements previous studies conducted on the corpus of the collection of his short stories published during his lifetime. Methods of linguistic stylistics, statistics (in terms of statistical parameters of the collocational compatibility and a comparative analysis of the use of the colour bilyi (white)), concept studies and corpus linguistics have been employed. The methods applied revealed high‑ and low‑frequency word combinations for the word bilyi (white); concepts actualized by using the lexeme under study; ethnolinguistic and literary language examples of the use of the color as compared to the context used in the short stories. Proposed is a structure of the entry word bilyi (white) for Vasyl Stefanyk’s vocabulary.

The article is devoted to the study of verbal identifiers of the enemy, their ranking in terms of normativity / abnormality of public communication is shown, and distinguished are stylistically neutral and stylistically colored language units. Described are the secondary nominations with negative connotations, as well as determining their communicative and pragmatic load. Achieving the goal was facilitated by the use of a descriptive method, methods of observation, contextual‑semantic and complex analysis. The corpus of the research material were national Ukrainian and regional mass media texts from 2022 to the beginning of 2023. It was found that during the specified time period, the linguistic identifiers of the invaders, which do not violate the canons of written forms of newspaper journalism, were activated. The secondary nominations are aimed at the expressiveness of language expression, the expression of contempt and hatred for one’s enemies and the creation of a specific communicative and pragmatic effect, which, although deaestheticizing the journalistic space, does reorganize the established media space, clearly reflecting the social perception of Ukrainians to the realities of the Russian‑Ukrainian war. The linguistic creativity of Ukrainian journalists expresses a combination of pathos and irony, usually employed to humiliate the Russian enemy.

Published: February 2024

Aquaculture is a crucial and rapidly expanding industry in global food production. Fisheries are also an essential socio-economic activity, providing abundant resources and remarkable prospects. However, due to the deteriorating ecological environment, aquatic animals are often exposed to traumatic conditions and are susceptible to bacterial infections that pose significant challenges for aquaculture production. The indiscriminate use of antibiotics in the past has led to the emergence of multidrug-resistant pathogens and sudden outbreaks of infectious diseases, resulting in serious economic losses. Moreover, the use of expensive chemotherapeutic drugs and antibiotics has negative impacts on aquatic environments. Therefore, it is increasingly important to adopt alternative natural agents, such as probiotics and their metabolites, to enhance healthy fish production. Probiotics are microorganisms that have numerous beneficial effects on their hosts. They are environmentally friendly, non-toxic, and cost-effective. This review specifically focuses on the use of Bacillus sp. as probiotics to promote healthy tilapia production in the aquatic sector, while also examining their interactions with the immune system and gut micro-biota. The information presented in this review can guide future research and promote effective and healthy tilapia culture production.

The present study investigated the impact of silver nanoparticles (Ag-NPs) on growth performance, carcass traits, liver and kidney functions, immunity and antioxidant indicators, digestive enzymes, and cecum bacteriology of growing rabbits. One hundred 5-week-old New Zealand White (NZW) male rabbits were randomly divided into 5 equal groups and fed for 8 weeks on the basal diet only or on the basal diet supplemented with different levels of Ag-NPs (0.25, 0.50, 0.75, or 1.00 mg/kg diet). Animals in each group were randomly distributed in 10 cages (replicates), with two rabbits each. Different dietary concentrations of Ag-NPs significantly increased live body weight (LBW) and feed conversion ratio (FCR). Also, body weight gain (BWG) increased dramatically during all experimental periods except 11–13 weeks of age. Levels of 0.25 and 1 mg of Ag-NPs/kg diet showed the highest increase in LBW, BWG, and FCR. All studied carcass traits, except liver %, were not affected by Ag-NPs levels. Rabbits fed diet supplemented with 1 mg Ag-NPs had the highest liver %. Serum total protein, albumin, and globulin levels were increased (P<0.05) in groups treated with 0.25 and 0.75 mg Ag-NPs. In contrast, serum values of aspartate transaminase (AST) and alanine transaminase (ALT), urea and creatinine were significantly reduced with the supplementation of Ag-NPs up to 0.75 mg/kg diet. The immunoglobulins M, G, and A (IgM, IgG, and IgA), complement 3 (C3) and lysozyme activity were improved with the inclusion of nano-silver in the rabbit feeds, particularly at the level of 0.25 mg Ag-NPs/kg feed. The inclusion of Ag-NPs in rabbit diets at different concentrations increased the total antioxidant capacity and the activities of superoxide dismutase, catalase, and glutathione peroxidase. Growing rabbits fed on diets supplemented with Ag-NPs had higher levels of digestive enzymes than the control group. The addition of Ag-NPs reduced the load of E. coli, Salmonella spp. and coliform in the rabbit cecum. Overall, the inclusion of 0.25–1 mg Ag-NPs/kg to NZW rabbit diets has shown beneficial effects on health and performance.

Current research responds to the need to add value to a product right from the conception phase and incrementally whenever the product’s customers demand it. Thus, this paper presents a hybrid method of adding value to a single-phase asynchronous motor by combining computerized modelling and simulation of a single-phase asynchronous motor with an incremental innovation technique based on value analysis and engineering for functional optimization of this device. The methodology combines these two techniques to obtain a customer-oriented product with optimally dimensioned functions that correspond to the needs of the device’s customers. The novelty of the work consists of the research methodology, which includes the application of functional analysis method during the design and redesign stages of a single-phase asynchronous motor.
The Synchronous Electric Machine with Variable Geometry Done by Elastic Permanent Magnets
Authors: Murgoci Dragoș , Adam Maricel
Published: February 2024

The paper refers to an electric machine (motor/generator) with an adjustable magnetic field, because its rotor has a special construction that allows the deformation of its elastic permanent magnets. The permanent magnets deform due to a clamping stroke parameter and in this way the flux density of the magnetic field as well as the width and length of the permanent magnets are variable. The variable magnetic field crosses the stator coils which are supplied by the voltages and due to a variable magnetic flux density, a higher torque will result even at lower values of the currents. As a result, a higher efficiency will be obtained due to the increase in mechanical power and the decrease in losses (e.g., Joule effect) in the stator windings. The presented electric machine is a synchronous machine with variable geometry, belonging to the category of permanent magnet machines. Specific to this machine is the fact that the rotor magnets are elastic, being made of ferritic compound rubber with neodimium magnets N45.

Published: February 2024

The purpose of this study is to build a cognitive model of the system–industrial complex of the Southern Federal District of Russia. The Southern Federal District is a region in the south of Russia, which includes the regions of Rostov, Volgograd, Astrakhan, and Krasnodar; the Republics of Adygea, Kalmykia, and Crimea; and the federal city of Sevastopol. The object of the study was the industrial complex of Southern Federal District, which ranks 6th in terms of the share of manufacturing among the federal districts. The study was conducted at the Southern Federal University, which is located in the Southern Federal District of Russia. This article discusses the use of the cognitive modeling method, which allows us to determine the degree of system stability and the direction of system development under varying degrees of influence of external factors. This method is used to build forecasts of the development of poorly structured socioeconomic systems. The cognitive modeling method made it possible to predict one of the scenarios for the development of the industrial complex of the Southern region of the Russian Federation. For the subject under study, indicative, controlling, and regulating peaks have been identified, but the difficulty of forecasting is noted due to the lack of a general program for the industrial complex of the federal district. The article presents scenarios of industrial development of the Rostov and Krasnodar regions as the most industrially developed regions in the Southern Federal District. Cognitive modeling allows building scenarios of development of the studied systems of regions by means of impulse influence, that is, when one vertex affects another vertex. The modeling results made it possible to build a cognitive map of the industrial complex of the Southern Federal District. This map showed that in the case of impulse impact on the industrial complex, it is necessary to strengthen regulatory measures on the part of the state.

Objective: The objective of this study was to identify locations with higher eutrophication and, consequently, susceptible to the emergence of macrophytes in the Barra Bonita reservoir, SP.
 
Theoretical background: The presence of macrophytes, such as Eichhornia crassipes, is influenced by ecological succession driven by human activities like introducing exotic species and discharging untreated nutrients. Effective management, including buffer zones, is suggested to reduce eutrophication, though some studies question their effectiveness on a large scale.
 
Method: The analysis of the Normalized Difference Vegetation Index (NDVI) was conducted using remote sensing images obtained from Landsat 8 and 9 satellites. As a criterion for data acquisition, corresponding data for the study region were obtained over a one-year temporal scale with a maximum cloud cover of 0%.
 
Results and conclusion: Analyzing the images, it is observable that the month of June 2023 exhibited areas with a higher vegetation index and, consequently, eutrophication processes. This trend gradually decreased in the months of August, September, and November.
 
Research implications: The analysis of satellite images revealed specific patterns of eutrophication, suggesting a direct correlation between the geographical distribution of nutrients and the potential proliferation of macrophytes. Additionally, comparative studies of nutrient concentrations in tributaries indicate that urban pollution, besides affecting local water quality, contributed to eutrophication in the Barra Bonita reservoir.
 
Originality/value: Through the NDVI, the eutrophication possibility in Barra Bonita’s Reservoir was evidentiated.

Authors: Arango Lopera Carlos Andrés , Rivera Betancur Jerónimo
Published: February 2024

Se plantea que en el biopic musical el problema de la identidad es uno de los signos distintivos, clave en estrategias narrativas como establecer comparaciones, referencias y puntos de cruce entre sus protagonistas y las carreras de otras estrellas de la música. Para estudiar este asunto se ha elegido la figura de Elvis Presley como correlato en las películas Gran bola de fuego (Great Balls of Fire!, Jim McBride, 1989) y En la cuerda floja (Walk the Line, James Mangold, 2005), que cuentan las historias de Jerry Lee Lewis y Johnny Cash.

Przedmiotem artykułu jest problematyka aspektu liturgicznego kanonicznej wizytacji biskupiej w parafii. Za cel opracowania postawiono ukazanie i wyjaśnienie na podstawie określonych przepisów, różnego rodzaju celebracji liturgicznych realizowanych w czasie wizytacji. Tak określone zamierzenie badawcze zrealizowano poprzez opis i gruntowną analizę obowiązujących przepisów i tekstów Magisterium kościelnego. Analiza wymienionych źródeł pozwoliła na sformułowanie kilku głównych wniosków. Po pierwsze wskazano, że wizyta duszpasterska jest jednym z najważniejszych wyrazów zaangażowania biskupa diecezjalnego w służbę powierzonemu mu ludowi Bożemu. Po drugie ukazano udzielanie sakramentów przez biskupa, a po trzecie, przedstawiono problematykę celebracji pozasakramentalnych form kultu Bożego.
Diecezjalne Komisje Liturgiczne jako postulat reformy liturgicznej. Perspektywa polska
Authors: Araszczuk Stanisław
Published: February 2024

Pierwszy dokument odnowy soborowej - Konstytucja Sacrosanctum Concilium został uchwalony 4 grudnia 1963 r. W dokumencie tym są zamieszczone wskazania, które stanowią fundament reformy liturgii oraz służą pełnemu, świadomemu i czynnemu udziałowi wiernych w sprawowaniu tajemnic Kościoła. Jednym z postulatów Konstytucji liturgicznej było utworzenie w poszczególnych diecezjach Komisji Liturgicznych, by popierały działalność liturgiczną pod kierunkiem biskupa (por. KL 45). Artykuł stara się odpowiedzieć na pytanie: czy postulat ten został już zrealizowany? Dotychczasową działalność Komisji Liturgicznych w poszczególnych diecezjach i ich skuteczność można różnie oceniać. W większości diecezji Kościoła w Polsce odegrały one bardzo pozytywną rolę w recepcji liturgicznej odnowy soborowej. Wydaje się, że obecnie, wobec różnych przejawów kryzysu Kościoła, Diecezjalna Komisja Liturgiczna podejmować zdecydowane działania w sprawie liturgicznej formacji duchowieństwa i wiernych świeckich, szczególnie w ich przygotowaniu do liturgicznych posług.

Maximizing Recovery in a Mature Rich Gas Condensate Field: Using Rate Transient Analysis to Identify Infill Opportunities
Authors: Al-Fazari I. , Govinda P. , Kalbani A.
Published: February 2024

Rate Transient Analysis (RTA) is a powerful technique in petroleum engineering that can be used to diagnose reservoir behavior, leading to better reservoir understanding and production optimization. In this study, RTA was used as a simple and agile analytical technique for the Field A reservoir. Field A is a rich tight gas condensate reservoir in a complex structure composed of six sub-units with varying geological characteristics located in Oman's north Field. The main purpose of this study was to understand the connected volume seen by existing wells and thereby identify sweet spots for future infills that would help maximize field recovery.

A clear and structured approach was followed in this study. First, the gap to top quartile was defined with an understanding of reservoir challenges and reservoir data uncertainties. Second, data were gathered to apply basic analytical techniques. Third, the analytical technique Blasingame was used to history match the connected pore volume. Fourth, a numerical technique was used to match the analytical approach, where the condensate banking effect was considered. Finally, the connected volume was estimated per well, and drainage areas were marked on a map to identify potentially undrained areas and infill opportunities.

Individual well RTA was performed for two blocks of the Field A reservoir, the East and West blocks, consisting of 31 wells in total. The effect of condensate dropout on the effective permeability-thickness (kh) of the reservoir was inferred from RTA. Well-level numerical models were generally able to match condensate-gas ratio decline trends and the effective kh reduction due to condensate banking. Changing skin was observed in many of the RTAs (initial negative skin gradually going towards 0), indicating gradual closure of hydraulic fractures. The study results indicate nine potential infill opportunities in both blocks of the Field A reservoir. The identified infill opportunities were ranked through economic evaluation, considering factors such as the cost of drilling and completing new wells, the expected increase in production rates, and the projected increase in reserves.

This study provides valuable insights for enhancing field performance and consequently improving field recovery. The study represents an agile approach in how field understanding, opportunities identification, and maturation can be developed quickly yet effectively using existing data and limited manpower in a limited time frame. RTA offers efficient analysis of changing reservoir and well conditions, surpassing limitations of traditional methods and dynamic simulation, providing a practical alternative for identifying infill opportunities and optimizing production strategies. The approach used can be replicated for other similar reservoirs, and the results have significant implications for the petroleum industry.
