SCALE FORMATION IN THE OIL AND GAS INDUSTRY AND THE TRANSITION TOWARDS «GREEN» INHIBITORS
Authors: Valekzhanin I.V.
Published: April 2024

Hydrocarbon production in oil field conditions invariably involves the joint production of significant amounts of water. Mineral salts of various compositions can precipitate from produced water under certain conditions. In the oil and gas industry, the deposition of mineral salts on the surface and underground production equipment can cause various problems, such as deterioration of reservoir properties, reduced production and premature failure of well equipment. Scale deposition can also lead to pump malfunctions, reduced efficiency of heat exchangers, reduced quality of commercial products and increased corrosion processes. Salt deposits lead to expensive restoration work, downtime in well operations and, ultimately, to an increase in the cost of produced hydrocarbons.As a result of the geochemical processes between the injected water and the formation water and the formation rock, as well as the complex composition of the formation fluids, controlling the formation of inorganic scales becomes a challenge. In the oil and gas industry, carbonate (calcium), sulfide (iron) and sulfate (calcium, barium, strontium) deposits are most often encountered. The formation of scale deposits depends on several factors, which include, but are not limited to, temperature, pressure, solution saturation and hydrodynamic flow characteristics.There are many approaches to managing scale deposits, but the most common currently is the use of chemical reagents – scale inhibitors. Traditional scale inhibitors contain phosphorus- and nitrogen-based chemicals as their active base, which can be harmful to the environment and human health. In this regard, in the world practice of oilfield chemistry, the direction of «green» chemistry is actively developing – reagents that can effectively prevent the formation of mineral salts with minimal negative impact on the environment and humans.This review discusses various scale types, methods for their removal, scale inhibitors of various natures and the mechanism of their work. Attention is also paid to «green» inhibitors and their development.

Begleitende Klagen über Ohrgeräusche (Tinnitus) bei einer Lärmschwerhörigkeit sind nicht selten. Je nach Krankheitswert kann eine Berücksichtigung bei der Schätzung der Minderung der Erwerbsfähigkeit (MdE) von 5–10 % integrativ erfolgen. Wegen der Unmöglichkeit, Tinnitus zu objektivieren, ist nicht nur zur Begutachtung eine audiometrisch gestützte Tinnitusanalyse zur Überprüfung der Plausibilität notwendig, die sich nach der Königsteiner Empfehlung 2020 der Deutschen Gesetzlichen Unfallversicherung (DGUV) richtet. Nach ihr steht ein Tinnitus nie im Vordergrund der Berufskrankheit Lärmschwerhörigkeit.
Klimawandel und Gesundheit (Folge 5): Pollenallergien in Zeiten des Klimawandels
Authors:   Villingen Institute of Public Health (VIPH, Habermann-Horstmeier Lotte
Published: April 2024

Die Zahl der allergischen Erkrankungen hat in den letzten Jahrzehnten weltweit stark zugenommen. In Deutschland ist die häufigste allergische Erkrankung der Heuschnupfen, eine Allergie gegen Pflanzenpollen. Da der Klimawandel Einfluss auf die Pflanzenentwicklung nimmt, kommt es zu Änderungen des Spektrums allergener Pollen, vor allem aber zu Änderungen hinsichtlich der Pollenflugzeiten, der Pollenkonzentrationen und der Allergenität der Pollen. Dadurch ändert sich auch die Art und Intensität der Exposition der Bevölkerung gegenüber allergenen Pflanzenpollen. Es sind daher Änderungen in den Bereichen Prävention, Diagnostik und Therapie nötig, die dieser Situation Rechnung tragen.
Culturology of Journalism: Academic and Pragmatic Dimensions
Authors: Korkonosenko Sergey
Published: April 2024

The article attempts to represent the culturology of journalism as a relatively new area of theoretical research and an autonomous academic discipline. From a scientific point of view, the basis for the separation of this direction should be found in the sectoral culturology forming process, which includes a number of disciplines such as, for example, cultural studies of religion, education, politics, everyday life and, in particular, media space; the article contains detailed references to the views and proposals of the scholars in cultural studies of art. In each case, specific object, subject, institutional status and development trajectories are determined, that directly concerns the journalism theory. At the same time, the author aims to identify those characteristics of the discipline that enable it to develop fruitfully in interaction with the real media industry and, most importantly and urgently, the professionals' training system. The importance of this area in the academic dimension increases if the real problems and tasks of mass information practice are reflected in research activities and ways to enhance it are identified, recommendations are made regarding improving and enriching the professional qualifications of media organizations employees. This is the principal methodological position of the author. The field of university journalism education deserves special attention, since cultural knowledge and skills should be among the core competencies of graduates and find application in their professional and creative activities. The article presents judgments and pedagogical approaches to solving this problem, which are found in foreign and domestic literature. The author reveals in detail the experience of St. Petersburg State University, where for decades the journalism culturology has been purposefully developing in research and educational projects of various forms.
Features of Chinese Media Coverage of the Special Military Operation (SMO) in Ukraine
Authors: Muzykant Valerii , Hu Ruiqi
Published: April 2024

With the beginning of the SMO in Ukraine, the world media began to actively publish news about the events taking place. China was no exception. Information from both sides of the military conflict is carefully analyzed by the Chinese audience, raising many questions about the smallest details of the Russian military operation. The relevance of the work lies in the fact that for the first time the key aspects of the media influence of the Chinese media on public opinion in the initial period of the Northern Military District were analyzed, when news from the battlefield was covered on media platforms both by the journalists themselves and by participants in the events equipped with smartphones. The emerging phrase “WarTok” began to mean posting the latest events from the battlefield and comments on them on the TikTok platform. The study took into account both the official media coverage of the SMO and the attitude of Chinese new media towards this event. The development of a special military operation as a media event was carried out by comparing the information index with the search index, as well as by comparing keyword searches and citations. The study revealed a trend of changes in the attitude of the Chinese media and the Internet community to this event, and the acceptance of the Russian position by the Chinese media community. Three Weibo accounts were studied (Russian Embassy in China, Ukrainian Embassy in China and Russia Today). Based on the results of the study, it can be stated that the term “Russian-Ukrainian conflict” has become established in the media field of the PRC, and the attitude of the Chinese audience to Russia’s actions is assessed as positive. On the one hand, this is due to the official position of the Chinese government itself, on the other, the Russian Federation has successfully used Chinese social networks for close and effective interaction with the Chinese media community, and, unlike the situation in Western social networks, has taken control of this discourse. The emerging media agenda, with social media becoming the main battleground for public opinion, is forcing the journalistic community to recognize the particular importance of state ownership and control of new media platforms during the unfolding media wars.
Innovative register and feminist critique in Mark Behr’s The Smell of Apples
Authors: Nabutanyi Edgar Fred
Published: April 2024

Mark Behr’s artistic exploration of the horrific legacy of Afrikaner racist and masculinist ideology in The Smell of Apples has attracted substantial critical attention. This is perhaps what has elevated his novel to a post-apartheid South African literary canon. While it has been read as an exculpatory narrative—an exploration of how white South Africans disclosed their complicity in apartheid’s atrocities and/or a disclosure of how the apartheid system violated their rights—there is critical blindness to other important themes that the novel grapples with. This is why I offer a limited reading of Behr’s critique of Afrikaner gender oppression. My exploration, which focuses on Behr’s exposition of gender discrimination of upper-middle class women in an Afrikaner society, is anchored on two questions: how does Behr deploy an innovative register—eavesdropping child witness-narrator and a written letter—to unveil the oppression of upper-middle class white South African women in the Afrikaner polity? Second, how does he script the feminist agency of the ‘mother of the nation’ figure who is muzzled by Afrikaner patriarchy? I foreground Maria Pia Lara’s thinking about the liberational potential of literary texts in my discussion of Behr’s exposition of the gendered oppression of certain categories of women by Afrikaner patriarchy.
’n Feministiese ondersoek na Bettina Wyngaard se misdaadfiksie
Authors: Ess Courtneigh
Published: April 2024

The recent discourse on black feminism in Afrikaans literature is strongly influenced by powerful and activist-oriented writers like Ronelda Kamfer, Lynthia Julius, and Veronique Jephtas. With their poetry and public statements, they have shaped the feminist discourse significantly. However, the recent discourse on feminism in Afrikaans largely overlooks the contributions of certain black Afrikaans women writers. Bettina Wyngaard, a black Afrikaans woman novelist, attempts to disrupt this silence and through her literature and opinion pieces, she advances an alternative feminist stance. This article focuses on Wyngaard’s contribution to the recent feminist discourse and the ways in which she asserts her voice within the debate. In this article I refer to three of her crime fiction novels, namely Vuilspel (Foul play) (2013), Slaafs (Slavishly) (2016) and Jagter (Hunter) (2019). I analyse these texts in attempt to examine the feminist ideology underlying her literature. I argue that Wyngaard chooses crime fiction, a genre traditionally dominated by white males, in attempt to sanction her voice within the feminism debate in Afrikaans. In this article, I examine Wyngaard’s crime fiction within the context of third wave of feminism, which engages with popular culture as a tool for critique and to promote feminist ideology. I explore the feminist consciousness and ideology in Wyngaard’s novels and the ways in which she challenges established patriarchal conventions in crime fiction as a genre. I employ Anne Cranny-Francis’ framework in the feminist value of crime fiction to examine the feminist themes in Wyngaard’s work.
Rab8a/SNARE complex activation promotes vesicle anchoring and transport in spinal astrocytes to drive neuropathic pain
Authors: Xiao Yunqiao , Wang Gengyi , He Guiqiong , Qin Wanxiang , Shi Ying
Published: April 2024

Neuropathic pain (NPP) remains a clinically challenging condition, driven by the activation of spinal astrocytes and the complex release of inflammatory mediators. This study aimed to examine the roles of Rab8a and SNARE complex proteins in activated astrocytes to uncover the underlying mechanisms of NPP. The research was conducted using a rat model with chronic constriction injury (CCI) of the sciatic nerve and primary astrocytes treated with lipopolysaccharide. Enhanced expression of Rab8a was noted specifically in spinal dorsal horn astrocytes through immunofluorescence. Electron microscopy observations showed increased vesicular transport and exocytic activity in activated astrocytes, which was corroborated by elevated levels of inflammatory cytokines such as interleukin (IL)-1β and tumor necrosis factor (TNF)-α detected through quantitative PCR. Western blot analyses confirmed significant upregulation of Rab8a, VAMP2, and Syntaxin16 in these cells. Furthermore, the application of botulinum neurotoxin type A (BONT/A) reduced the levels of vesicle transport-associated proteins, inhibiting vesicular transport in activated astrocytes. These findings suggest that the Rab8a/SNARE pathway in astrocytes enhances vesicle transport and anchoring, increasing the secretion of bioactive molecules that may play a crucial role in the pathophysiology of NPP. Inhibiting this pathway with BONT/A offers a novel therapeutic target for managing NPP, highlighting its potential utility in clinical interventions.
CUT&RUN abbreviated protocol v1
Authors: Janssens Derek , Henikoff Steven , - CG
Published: April 2024

We previously described a novel alternative to Chromatin Immunoprecipitation, Cleavage Under Targets & Release Using Nuclease (CUT&RUN), in which unfixed permeabilized cells are incubated with antibody, followed by binding of a Protein A-Micrococcal Nuclease (pA/MNase) fusion protein. Upon activation of tethered MNase, the bound complex is excised and released into the supernatant for DNA extraction and sequencing. In the manuscript attached to this version of the protocol, Meers et al. introduce four enhancements to CUT&RUN: 1) a hybrid Protein A-Protein G-MNase construct that expands antibody compatibility; 2) a modified digestion protocol that prevents premature release of the nuclease-bound complex; 3) a calibration strategy based on carry-over of E. coli DNA introduced with the fusion protein; and 4) a novel peak-calling strategy customized for the low-background profiles obtained using CUT&RUN. Here we provide an updated CUT&RUN protocol that incorporates these enhancements, and provides three different options for the CUT&RUN MNase digestion reaction that are helpful to improve data quality or to increase throughput. These new features, coupled with the previously described low-cost, high efficiency, high reproducibility and high-throughput capability of CUT&RUN make it the method of choice for routine epigenomic profiling.

The analysis of DNA nucleotide sequences is an important source of information in the identification of plant taxa or plant components in the composition of medicines. In this work, we studied the possibility of using universal molecular markers for DNA barcoding of rare plant species distributed in the Altai Biosphere Reserve, located in the Altai Republic (South Siberia, Russia). In order to identify commercially-used endangered species, universal markers recommended for DNA barcoding were applied: ITS (Internal Transcribed Spacers) region of nuclear ribosomal DNA and four regions of chloroplast DNA: trnL-F, trnH-psbA rpl32-trnL, and rpl16. Among 61 species of rare flowering plants protected in the Altai Biosphere Reserve, ten species belonging to eight families were studied. The results of sequencing showed that ITS, rpl32-trnL and trnH-psbA core plant barcodes are the most effective markers for discriminating rare species from the Altai Biosphere Reserve.
THEORETICAL-METHODOLOGICAL CONCEPTUALIZATION OF THE NATIONAL MENTALITY DEFINITION (ON THE EXAMPLE OF UKRAINIAN COSSACKS AND THEIR CHARITY)
Authors:   Pereyaslav-Khmelnytskyi State Pedagogical University named after Hryhoriy Skovoroda, Kotsur Vita
Published: April 2024

Theoretical and methodological study of the Cossack mentality in Ukrainian scientific works demonstrates the significant interest in the uniqueness of the Ukrainian Cossacks, their way of life, character, worldview and self-identity. We should notice that the choice of used methodological approaches is because of high level of controversy of a peculiar situation. The sense of the discussions leads primarily to the ratio of Marxist to non-Marxist, “traditional” and “new” methodologies in the post-Soviet historiography. A sign of nowadays is the involvement of Ukrainian researchers in the discussion of theoretical and methodological problems of modern science, especially of mentality. The author studied the following research methods: typology method – to study the basic concepts of the terminological apparatus, to mark theoretical and methodological research of national mentality, its elements in sociological, historical and psychological literature; descriptive and system and functional ones – to analyse the state of ethnopsychology research; to outline the factors that influenced the formation of the mentality of the Cossacks and how their worldview, moral and ethical principles, persuasions affected the formation of modern worldview and self-identity of Ukrainians. The method of theoretical modelling and the system method were used by the author to extrapolate the Ukrainian mentality in domestic and foreign scientific researchers. Since the article also provides a historiographical analysis of works on the phenomenon of the Cossacks, the reconstruction of their moral, ethical and ideological image, we should note that we used an anthropological methodology. Its supporters believe that the central place in history should be occupied by human as an effective social being with own ideas, feelings and persuasions. It should be emphasized, that such a kind of anthropocentrism is a special importance for Ukrainian historiography The article shows features of the phenomenon of the Ukrainian Cossacks through the vision of modern theoretical and methodological criteria of this issue. An important part of clarification on the Cossacks mentality is works devoted to the charity that was common among the Cossacks.
Contemporary Theoretical and Methodological Approaches to Investigating the Cognitive Aspects of Sports Performance: An Analysis of Foreign Research
Authors: Tcepelevich M.M. , Bolshakov V.V.
Published: April 2024

The article examines foreign modern theoretical and methodological approaches to the study of cognitive aspects of sports performance. A classification of approaches is presented, based on the type of tasks, the phenomenon under consideration, and the explanation of the cognitive differences between athletes and the control group. Expert performance approach, cognitive component skill approach, and ecological dynamic approach are discussed, including their theoretical foundations, key results, and employed paradigms. The expert performance approach assesses perceptual-cognitive abilities utilizing context-specific stimuli derived from photographs or videos of sporting scenarios. This approach underscores the significance of domain-specific knowledge and practical experience in achieving a high level of proficiency in sports. The cognitive component skill approach delves into the fundamental cognitive mechanisms underpinning sporting expertise by employing cognitive paradigms in laboratory settings. The ecological dynamics perspective posits that a crucial cognitive skill for athletes is the ability to perceive affordances, defined as opportunities for action determined by environmental constraints, and to effectively translate perceived affordances into motor execution. The article discusses the advantages and limitations of each approach and provides criteria to guide the development of research concepts and sports testing methods.

Published: April 2024

Background: Hepatitis B virus (HBV) infection is a global public health problem affecting about two billion people worldwide. About 95% of the infection is acquired during the perinatal period. Though studies have been carried out on these in different parts of Nigeria, information regarding the prevalence and risk factors of HBV infection in antenatal clinic attendees in south-south Nigeria is scanty. We determined the sero-prevalence of hepatitis B surface antigen (HBsAg) and the associated factors among pregnant women in south-south, Nigeria.
Methods: A retrospective study carried out at the antenatal clinic of Rivers State university teaching hospital (RSUTH) between 1st January, 2015 and 31st December, 2020.  At booking visit, 9,990 women were tested for HBsAg. Data was analyzed using the IBM SPSS version 23.0. P<0.05 was considered statistically significant.
Results: A total of 9,990 women were screened for HBV infection. Prevalence of HBV infection was 160 (1.6%). Age group 30-39 years had most HBV infection, 103 (64.4%). Most who were positive for HBsAg were married 158 (98.7%), traders 45 (28.1%), para 2-4, 65 (40.6%); in their second trimester, 78 (48.8%) and with tertiary level of education 111 (69.3%). Associated factors of HBV infection with statistically significant difference in proportion of HBsAg positives and negatives include gestational age, educational status, occupation, presence of HIV and VDRL.
Conclusions: Although the study reveals a low prevalence of HBV infection, continued routine screening for HBV infection is highly recommended.

Published: April 2024

Background: In 2020, infections caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are still a pandemic, including in Indonesia. Numerous efforts have been made to reduce morbidity and mortality rates caused by the virus, including vaccination. The existence of a vaccine for COVID-19 in the Indonesian community faces pros and cons. The achievement rate of vaccination, in general, is still not as expected. To accelerate vaccination, the government through the Ministry of Health has issued a circular on the acceleration of COVID-19 vaccination for children from 12-17 years old. The study aims to assess the relationship between the level of knowledge and willingness to vaccinate against COVID-19 in adolescents from 12-17 years old in Sambutan Village, Samarinda city, Indonesia.
Methods: This study is observational analytic with a cross-sectional design. We took samples through online questionnaires distributed to adolescents aged 12-17 years old, in Sambutan village, Samarinda city from September to December 2021.
Results: The sample was 179 people, consisting of 86 people (48.04%) male and 93 people (51.96%) female. Based on the knowledge level, 144 (80.4%) have good knowledge and 35 (19.6%) have less knowledge about vaccination. As for the willingness to vaccinate, 150 (83.8%) people are willing, and 29 (16.2%) are unwilling to be vaccinated. The analysis test, obtained p<0.001, indicating that there is a relationship between the level of knowledge and willingness to vaccinate.
Conclusions: The better adolescents comprehend vaccination, then their willingness to be vaccinated is higher.

Published: April 2024

Background: Neutral constitutional alignment and neutral joint line obliquity has been the standard alignment strategy for total knee arthroplasty. This one-for-all measure may negatively impact gait pattern and knee biomechanics. Novel alignment strategies surged, considering the variability in phenotypes found across the literature, as different populations may present different phenotype distributions. The Portuguese population has a distinct genetic origin, with no phenotype distribution data. Our objective was to characterise the population’s knee morphology, searching and analysing adjacent joint osteoarthrosis, and calculating the pre-disease coronal alignment.
Methods: A retrospective cohort study was conducted. Full-length X-rays performed between 2016-2023 were analysed. Five alignment parameters were measured (LDFA, MPTA, JLCA, TJLA, HKA), and two parameters were calculated (aHKA, JLO). Knees were classified according to the CPAK classification.
Results: For the arthritic cohort, CPAK-I (23%) II (20%) were most common, aHKA increases as KL increases (r=0.8352; p<0.001). For the healthy, Type-II (42%) and Type-I (15%) were most common. For paediatric, Type-II (43%) and Type-V (21%) were most common. CPAK Types-VII/VIII/IX were rare. Differences between genders for healthy and arthritic cohorts were statistically significant. The arthritic had higher prevalence of adjacent joint osteoarthritis.
Conclusions: The Portuguese population presents a similar knee phenotype comparing with other populations, some differences have been found regarding the Asian continent. The most common phenotype was a neutral alignment if either healthy or paediatric, or a varus alignment if knee OA. Coronal alignment may not have a major impact in the prevalence of ankle and hip osteoarthritis; however, higher prevalence is observed in patients with knee OA.

The field of forensic science necessitates the utilization of efficient techniques for the enhancement of latent fingerprints. Environmental issues are frequently raised when traditional approaches are employed in this context. This study introduces an innovative and ecologically responsible solution to this challenge in the form of Alternanthera Dentata (AD) leaf powder. AD is renowned for its striking and vivid deep purple leaves, and it unveils remarkable properties as a natural pH indicator. Its distinctive characteristic lies in the ability to undergo a vivid transformation from a rich crimson hue to a greenish-yellow tint, responding to alterations in pH levels, a phenomenon attributed to its anthocyanin content.

The research demonstrates the versatility of AD leaf powder across diverse surfaces and its distinctive ability to indicate pH levels. The use of methanol for AD leaf powder extraction enhances the sensitivity of anthocyanins to pH fluctuations. The innovative approach not only proves the efficacy of AD leaf powder in enhancing fingerprint clarity but also emphasizes its eco-friendliness and cost-effectiveness.

This study establishes Alternanthera Dentata (AD) leaf powder as a promising and sustainable solution for latent fingerprint enhancement in forensic science. The compatibility of AD with various surfaces, coupled with its natural pH indicator properties, positions it as a valuable resource. The incorporation of methanol further boosts sensitivity, highlighting the eco-friendly and cost-effective nature of this innovation. By embracing environmental sustainability principles, this research contributes to a greener and more responsible future for forensic science applications.

Published: April 2024

Forward Head Posture (FHP) refers to a condition where the head protrudes forward, significantly contributing to neck pain and being associated with decreased productivity and psychological distress. This study investigates the nuanced classification of FHP and proposes a universally applicable methodology for its identification and analysis using deep learning. Leveraging the Korean Facial Image (K-FACE) dataset, rigorous image preprocessing with the Yolo-v8 model was conducted to facilitate accurate measurement of the CranioVertebral Angle (CVA) from various perspectives. The study meticulously evaluated the classification effectiveness of three advanced deep learning models: EfficientNet-B7, NFNet-F7, and ResNet-152. Among these, EfficientNet-B7 demonstrated superior performance with an accuracy of 0.69 and a recall score of 0.69 compared to other models. Additionally, comparisons based on camera angles within the EfficientNet-B7 model highlighted its excellence, particularly at the ±75° angle. The importance of image regions in EfficientNet-B7 was confirmed through Grad-CAM analysis, emphasizing the critical role of the neck region in accurately classifying FHP images. This comprehensive performance comparison and the proposed detailed classification methodology underscore the potential for generalization in FHP classification. Furthermore, by leveraging a unique dataset and employing state-of-the-art classification techniques, this research offers a novel perspective on the discourse surrounding FHP. Future research could integrate expanded facial image datasets and apply transfer learning techniques to further enhance the precision of FHP classification, thereby improving diagnostic accuracy and offering targeted interventions for individuals experiencing neck pain associated with FHP.

Published: April 2024

Food is a fundamental human need. Food must be provided in sufficient quantity, be of good quality, be safe to consume, and be affordable. Furthermore, the determining factor of household food consumption is income. If income increases, the consumption pattern of nutritious food will also improve. The study aimed to analyze the characteristics of female vegetable farmers, their household food consumption, and the determinants of household food consumption in Pekanbaru City. The research data were obtained through an interview survey, with 65 female vegetable farmers selected using simple random sampling. This study found that female vegetable farmers in Pekanbaru City were of productive age, had a high school education level, and mostly had 3-4 family members. The household food consumption of the participants fulfilled the PPH score target for Pekanbaru City but did not fulfill the national target. Therefore, the household food security of female vegetable farmers in Pekanbaru City has not been achieved nationally. The study further revealed that household income, number of family members, and education of female vegetable farmers were significant determinants of household food consumption. In contrast, the age of female vegetable farmers did not significantly affect household food consumption. Overall, the study highlights the importance of improving the food security of female vegetable farmers in Pekanbaru City by addressing the significant determinants of household food consumption. This can be achieved by implementing policies and programs to increase household income, improve education levels, and reduce family size.

Published: April 2024

Fresh pandan leaf fragrance has been applied to enhance the aroma of many traditional foods. However, the fresh leaf has a limited shelf life—only 1 day after harvest. Therefore, in liquid or powdered form, pandan extract can be utilized as an alternative aromatic component in food production. The purpose of this study was to determine the effect of extraction temperatures (50, 60, and 70°C) utilizing microwave-assisted extraction (MAE) and the ratio of pandan leaf as material to ethanol as solvent (1:3, 1:7, and 1:11) on the characteristics of pandan extract in liquid form. The study found that the properties of pandan extract treated at MAE 60°C with a material-solvent ratio of 1:7 were the best among all treatments. The pH of this liquid pandan extract was 5.31, the antioxidant activity was 32.86 ppm, and the chlorophyll content was 7.76 mg/L. The powdered pandan extract generated by drying the liquid pandan extract using a spray dryer and adding maltodextrin had properties such as water activity 0.45, solubility 96.09%, solubility rate 0.01 g/s, color L 85.65, a* -6.68, b* 8.51, yield 3.88%, and was detected to contain 0.17% of the aromatic compound 2-acetyl-1-pyrroline. Powdered pandan extract has the potential to be developed as an aromatic food additive. Panelists liked the Lumpang cakes, a traditional cake consisting of rice flour and coconut milk made by adding 1% pandan leaf extract powder.

Published: April 2024

In the future, 3D food printing may be a fruitful area for the food industry. The presence of this technology opens the public's eyes to a revolution in the food sector, where food processing is limited to the conventional. The existence of this technology will also make food production much more effective and efficient. However, there is a problem when the 3D Food Printing process is carried out; when object defects occur, there will be material waste. This research proposes deep learning-based defect detection for defect and non-defect objects. This model mainly uses CNN as a deep learning method. The dataset is taken from the image of the print process performed at the time of object creation to be trained and validated to check the effectiveness of the proposed model. The architecture used uses pre-trained CNN models namely Inception-V3 and ResNet50 with the hope of classifying images that have a higher viscosity of the material. Where the model has been tested with previous datasets and applied with 3D Food Printing datasets with a dataset division ratio of 85% which is training data and 15% is validation data. After testing the two proposed scenarios, the accuracy result obtained in the test model scenario 1, Inception-V3, is 84.62% and for the test model scenario 2, ResNet50, the accuracy is 93.83%. The outcomes also demonstrate that improved accuracy, loss, and classification time may be obtained by applying CNN in conjunction with data augmentation.

This process consists of market participants' behavior and price formation. This research aims to investigate the curly red chili market behavior and to analyze the price formation and price transmission elasticity in Bengkulu Province. Panel data were obtained from retailers and farmers during a month. Data were analyzed using qualitative descriptive analysis for market behavior, while linear regression was used for the factors affecting price formation and price transmission elasticity. The result of market behavior analysis indicates that collecting traders buy the chili from farmers, then sell it to the next level sellers without any treatment. If the farmers have no debt and price agreement, they negotiate the price with the traders. On the other hand, if the farmers have a loan and there is a price agreement, the price is determined by the moneylender. Furthermore, the chili price at retailers is formed by following the price change on the previous day, and it is also influenced by the price at previous traders. It can be concluded that the marketing system has a vertical effect and backward linkage between its elements. The chili price transmission elasticity is 0.675. This empirical result concluded that the rate of price change by 1 per cent at the consumer level would cause a price change of only 0.675 per cent in the trader stage. Thus, the market system is inefficient, and it is competing imperfectly.

W artykule przedstawiono stan wykorzystania energii geotermalnej w wybranych krajach UE w dwóch kierunkach: w procesie produkcji energii elektrycznej oraz do wytwarzania ciepła. W Polsce udział zainstalowanej mocy energii elektrycznej pochodzącej z energii geotermalnej wynosi zaledwie 0,27% mocy pozyskanej ze wszystkich źródeł OZE, zaś pozyskanie ciepła jest odpowiednio na poziomie 26,03%. Zwrócono uwagę, że zasoby geotermalne są użytkowane na różne sposoby i z różną intensywnością. W globalnym wykorzystaniu tej energii pierwsze miejsce zajmują geotermalne pompy ciepła. O ich wysokim potencjale wdrożeniowym decydują między innymi skala zastosowań i pozytywne opinie dotychczasowych użytkowników, dostępność rozwiązań technicznych w tym zakresie na całym rynku wewnętrznym UE, bogata oferta ze strony producentów pomp i instalatorów, często wzbogacona o możliwość współpracy z systemami fotowoltaicznymi czy magazynowaniem ciepła, a także możliwość uzyskania wsparcia finansowego inwestycji. Dopiero drugie miejsce w aspekcie wykorzystania energii geotermalnej zajmuje ciepłownictwo sieciowe. W tym przypadku koszty przedsięwzięcia niezwykle wzrastają w związku z koniecznością wykonania sieci otworów wiertniczych czy ze względu na ryzyko, jakie niesie ze sobą proces poszukiwań horyzontów geologicznych o pożądanych parametrach hydrotechnicznych i do tego w perspektywicznym interwale czasowym. Zaprezentowano wieloletni program rozwoju wykorzystania zasobów geotermalnych w Polsce na lata 2022–2040, a w pewnych obszarach do roku 2050, opublikowany przez Ministerstwo Klimatu i Środowiska. W ramach realizacji tego programu ustanowiono między innymi projekt pod nazwą „Udostępnienie wód termalnych w Polsce” – dotyczący odwiercenia 15 otworów dla poszukiwania i rozpoznania wyżej wymienionych wód w najbardziej perspektywicznych rejonach kraju pod względem możliwości eksploatacji źródeł geotermii głębokiej. Przedstawiono priorytetowe programy dotacyjne ukierunkowane na rozwój ogrzewnictwa indywidualnego, cieszące się w Polsce bardzo dużym zainteresowaniem. W programach takich jak „Mój Prąd”, „Moje Ciepło”, „Czyste Powietrze” istnieje możliwość uzyskania dofinansowania ze środków unijnych, między innymi do instalowanych pomp ciepła. Omówiono prace badawcze zrealizowane w Instytucie Nafty i Gazu – Państwowym Instytucie Badawczym, między innymi w zakresie możliwości wykorzystania sczerpanych złóż węglowodorów dla celów geotermalnych, biorąc pod uwagę możliwość zastosowania CO2 jako nośnika energii geotermalnej w procesie jego sekwestracji. Zaprezentowano zagadnienia tworzenia numerycznych modeli obiektów geotermalnych, doboru odpowiednich receptur płuczek wiertniczych, zaczynów cementowych czy płynów eksploatacyjnych przy uwzględnieniu podwyższonych temperatur i ciśnień.

Malnutrition, a significant global health concern, necessitates innovative solutions to enhance food nutritional profiles sustainably. This study focused on augmenting the nutrient content of traditional cereal flours, specifically corn (Ma) and millet (Mi), by incorporating edible insects, Macrotermes subhyalinus (MS) and Cirina butyrospermi (CB) known for their high protein, vitamin and mineral levels. The research aimed to create fortified flour formulations by adding these insects at various proportions (20%, 22.5% and 25%), thus addressing nutritional deficiencies common in staple diets. The study employed a comprehensive methodological approach incorporating biochemical analyses to measure protein, lipid content, pH and vitamin C levels in 16 distinct flour blends. These measures provided a basis for evaluating the nutritional enhancement achieved through insect incorporation. Additionally, nutrient density calculations and statistical analyses including analysis of variance (ANOVA) and post-hoc tests were conducted to assess the overall nutritional value and identify significant differences among formulations. Results demonstrated a marked improvement in the nutritional quality of cereal flours with insect addition. Formulations MiMS25 (75% Millet + 25% MS) and MiCB25 (75% Millet + 25% CB) exhibited the highest mineral content, with ash values of 3.69 ± 1.00% and 2.60 ± 0.28%, respectively. Protein levels were significantly increased in MaCB22.5 (77.5% Corn + 22.5% CB) and MiCB25 showing concentrations of 18.78 ± 0.20% and 18.66 ± 0.10%. Furthermore, the inclusion of MS notably enhanced lipid content, particularly in MiMS25 which displayed an energy value of 451.19 kcal. Among the tested blends, MaCB22.5 was identified as the most nutritionally promising with a nutrient density score of 0.255 indicating a balanced and improved nutritional profile. This study underscores the potential of integrating edible insects into cereal flours as a sustainable strategy to combat malnutrition. It highlights the need for further research into optimizing these formulations for consumer acceptance, taste, and shelf-life aiming to incorporate them into mainstream diets to achieve global nutritional well-being.

Background. Complications after revascularization in individuals with peripheral atherosclerosis and diabetes mellitus can lead to negative results of surgical interventions against the background of critical ischemia.

   Objective. The aim of the study was to identify predisposing circumstances for the development of certain complications after reconstruction in patients with critical ischemia and diabetes mellitus.

   Materials and methods. A prospective study of the results of reconstructive interventions was carried out in 78 patients with trophic disorders on the background of peripheral atherosclerosis and diabetes mellitus. Complications were detected in 25 cases (the main group), 53 patients had uncomplicated course of the postoperative period. The influence of concomitant diseases, peculiarities of surgical treatment on the occurrence of adverse outcomes was analyzed.

   Results. Manifestations of heart failure increase the likelihood of arterial thrombosis (p < 0.05). Signs of hepatic dysfunction increase the frequency of PE in the perioperative period (p < 0.05). Adequate correction of hypergly-cemia reduces the risk of stroke.

   Conclusion. The data on the circumstances predisposing for the development of complications make it possible to prepare more carefully for reconstruction against the background of critical ischemia in people with peripheral atherosclerosis and diabetes mellitus and minimize the number of adverse outcomes of intervention.
