Design and analysis PSO based Fuzzy PID controller for Load frequency and voltage of the synchronous generator
Authors: Lemma Bisrat Gezahegn , Abebe Yidnekachew
Published: January 2024

The paper presents Automatic Voltage Regulator (AVR) and Automatic Generation Control (AGC) systems to manage real and reactive power and maintain a system's steady state. A change in system load affects its voltage and frequency. Due to unseen load changes, it is challenging to manage load frequency and voltage to keep them within the allowed limit. A control action must be required for automatic generation control to manage the load frequency and voltage. The Automatic generation control balances system generation with load and losses. The load frequency control (LFC) maintains the voltage profile, managing the active power flows inside the appliance, while the automatic voltage regulator keeps the bus bar voltage within acceptable limits by maintaining the synchronous generator's terminal voltage. An Integral Absolute Error (IAE) is taken as an objective function. PSO optimizes the Fuzzy-PID controller's gain and performance. The evaluation of frequency deviation and voltage fluctuation with time is carried out for single-area systems using the MATLAB 2021a program. The deviation of frequency response and voltage is reduced using the Fuzzy-PID controller, which is based on particle swarm optimization. PID-based traditional controller and a fuzzy-PID controller are compared. The PSO-based Fuzzy-PID controller proved more effective than the traditional control. The Integral Absolute Error (IAE) value for PID is 1.553 whereas the Integral Absolute Error (IAE) value for the PSO-based Fuzzy-PID is 0.6793. Therefore, the result shows that PSO-based Fuzzy-PID performs better than a PID controller.

Purpose
To analyze the diagnostic delay in malaria related to misdiagnosis at first visit medical visit and its association with the risk of severe malaria in non-endemic areas.
Methods
Retrospective observational study of sub-Saharan migrants with imported malaria from January-2010 to December-2022. Patients were allocated in two groups if they were tested for malaria at first medical visit or not. Time delays in seeking healthcare, medical diagnostic delay and total diagnostic delay were calculated.
Results
297 patients were included in the analysis. At first medical visit, malaria was misdiagnosed in 137 patients (46.1%). Medical diagnostic delay and total diagnostic delay were larger for the misdiagnosis group than for those properly diagnosed at first visit (p < 0.001). Although time in seeking healthcare was shorter in the misdiagnosis group, the presence of suggesting symptoms, such as fever, was lower (p < 0.050). Misdiagnosis was more frequent in emergency rooms linked to primary healthcare (p < 0.001). For the overall population (n = 297), total diagnostic delay was mainly due to delay in seeking healthcare. Initial misdiagnosis was associated with a higher risk of severe malaria (adjusted OR 2.23 [1.09–5.10], p = 0.031).
Conclusion
In a non-endemic area with a high rate of imported malaria, the percentage of patients misdiagnosed is surprisingly high. Misdiagnosis is associated with longer medical and total diagnostic delays and with a higher risk of severe malaria. It seems necessary to redesign training programs to improve knowledge among healthcare professionals and actions targeted to travelers to promote seeking healthcare advice promptly.
Ruthenium-106 Brachytherapy and Central Uveal Melanoma
Authors: Grajewski Luise , Kneifel Christiane , Wösle Markus , Ciernik Ilja F. , Krause Lothar
Published: January 2024

Purpose
Uveal melanoma (UM) is the most common primary ocular malignancy. The size of the tumor and its location are decisive for brachytherapy with β-emitting Ruthenium-106 (Ru-106) plaque. The treatment of juxtapapillary and juxtafoveolar UM may be challenging due to the proximity or involvement of the macula and optic nerve. High recurrence rates have been observed.
Methods
Central UM was defined as a lesion up to 5mm off the optic disc or fovea- radius of 5mm. Between January 2011 and July 2020, we treated 56 patients with Ru-106-brachytherapy. The clinical outcome for recurrence, visual acuity, and radiation-related toxicity was assessed. The follow-up was 66 (6-136) months.
Results
Of the 56 patients (56 eyes), eight patients (14%) suffered from local recurrence. Six relapsing UM of 19 patients (32%) were located close to the optic disc, and two patients had UM close to the macula (2/37, 5%), (p > 0,05). The overall rate of eye preservation was 89%. Visual acuity (VA) before treatments was 0,45 and was reduced to 0,26 after brachytherapy. Radiation retinopathy or opticopathy was detected in seven patients (13%), and radiation maculopathy in ten patients (17,9%). Six patients (11%) underwent enucleation due to recurrence or radiation-induced ophthalmopathy.
Conclusion
Therapy of central UM is challenging. We suggest, that central UM should be categorized as lesions laterally or medially to the fovea due to different likelihood of long-term control rates. Localization near the optic disc requires thoughtful management.
Comparison of the predatory impacts of indigenous and adventive ladybeetle species (Coleoptera: Coccinellidae) using a functional response approach

Published: January 2024

Biological control has long been recognized for its economic and ecological benefits as a pest management approach, but the use of non-native natural enemies has raised concerns about potential risks and unintended consequences. Indigenous predatory ladybeetles, such as Oenopia conglobata, play a crucial role in controlling many sap-sucking pests, including Agonoscena pistaciae, which is the most destructive pest of pistachio trees in Iran and other pistachio-growing regions worldwide. However, the abundance of Oenopia conglobata has recently decreased due to the presence of an adventive predatory ladybeetle, Menochilus sexmaculatus. To better understand the potential risks associated with this adventive species, we investigated the functional responses of female adults of M. sexmaculatus and O. conglobata against the third and fourth instar nymphs of A. pistaciae and Aphis gossypii. Our findings revealed that both predators exhibited a type II functional response, with O. conglobata demonstrating a significantly higher attack rate against A. pistaciae nymphs than A. gossypii nymphs. In contrast, prey species did not have a significant effect on the attack rate of M. sexmaculatus. Notably, M. sexmaculatus displayed the highest predation rate and voracity against both prey species. These results provide valuable insights into the potential risks of M. sexmaculatus for indigenous predatory species like O. conglobata. The fact that M. sexmaculatus exhibits higher voracity for both prey species than O. conglobata does suggest that it may pose a threat to the native ladybeetle population, highlighting the need for further research and careful consideration when introducing non-native natural enemies for pest management.
Quantum image encryption algorithm based on Fisher-Yates algorithm and Logistic mapping
Authors: Fan Ping , Zhang Yiteng
Published: January 2024

The parallel computing power of quantum computing and the special properties of qubits provide an effective solution for image processing tasks. This paper presents a quantum image encryption algorithm based on Fisher-Yates algorithm and Logistic mapping. Firstly, the Fisher-Yates algorithm is used to generate three key sequences, one of which is used to encode the coordinate qubits of the image. Using the other two keys and the preset rules, the quantum coordinate scrambling operation is designed based on the encoded coordinate qubit, which effectively scrambles the spatial information of the plaintext image. Next, another set of key sequences is generated, one of which is used to encode the color qubits of the image. Using two other key sequences and different rules, a qubit plane scrambling operation based on coded color qubits is designed, and the color information of image is scrambled successfully. Finally, the quantum key image is generated based on Logistic mapping, and the key image is scrambled based on Fisher-Yates algorithm to improve the key complexity. The final ciphertext image is obtained by performing XOR operation between the original image and the scrambled key image. The complete quantum circuit diagram of the scheme is given in this paper. The experimental results and security analysis prove the effectiveness of the scheme, which provides a large key space and the computational complexity is only O(n).

Authors: Sun Yuran , Chen Canping
Published: January 2024

Digital technology is a key technology for agricultural digitization, and administrative penalties are the main policy tool to regulate the behavior of enterprises. How do administrative penalties on digital technology companies (i.e., digital technology administrative penalties) affect the development of agricultural digitization? This paper applies deterrence theory and conducts empirical tests based on Chinese urban data from 2008 to 2020 to investigate the impact of digital technology administrative penalties on agricultural digitization and its mechanisms.The findings showthat digital technology administrative punishment can promote the development of agricultural digitalization in three aspects: digital technology, financial support, and talent capital through deterrence.Further analysis revealsthat digital technology administrative punishment can promote agricultural digitization by enhancing digital technology entrepreneurship and social risk-taking. This study provides new evidence on the impact of government legal regulations on agricultural digitization. It expands the research on the relationship between digital technology administrative penalties and agricultural digitization from a new perspective of post-punishment.

Effect of dietary protein reduction on growth performance and water quality of the blue streak hap Labidochromis caeruleus (Fryer, 1956) reared in a biofloc system
Authors: Yılmaz Melis , Erdoğan Fatime , Erdoğan Mete
Published: January 2024

The 8-week study evaluated the effect of dietary protein reduction on growth performance and water quality of blue streak hap (Labidochromis caeruleus) using biofloc technology (BFT). Fish averaging 0.67 ± 0.13 g in weight were distributed into 18 polyester tanks, each with a water volume of 60 L within 100 L tanks, accommodating 15 fish per tank. Four isolipidic and isoenergetic diets were formulated with gradually decreasing protein levels (40%, 35%, 30% and 25%). Four biofloc groups (40P + BF, 35P + BF, 30P + BF, and 25P + BF) and control (C) (40P + without BF) were fed twice daily (09:00 and 17:00) at a rate of 5% of their body weight. Molasses was added to the experimental tanks on a daily basis as an organic carbon source. This ensured that the biofloc tanks had a balanced carbon/nitrogen (C/N) ratio and facilitated control of total ammonia nitrogen (TAN), nitrite-nitrogen (NO2-N) and nitrate-nitrogen (NO3-N) levels. The nutritional composition of the bioflocs obtained from the experimental groups revealed that the crude protein and crude lipid contents were 37.00-38.14% and 1.45–1.52%, respectively (P > 0.05). The best specific growth rate (SGR) (1.68%) and feed conversation ratio (FCR) (2.21) were determined in the 35P group. Based on the overall evaluation of the study's data, it can be concluded that the dietary protein for the blue streak hap (L. caeruleus) can be reduced from 40–35% in a biofloc system without any negative effects on health. Improving water quality and providing additional food to fish through zero water exchange and organic carbon addition (BFT) can be considered as a sustainable aquaculture technique that can be used in ornamental fish farming.

Published: January 2024

Objective: The succinylation level of the AMPKα1 protein at K266 is higher in non-small cell lung cancer tissues than normal tissues, but its relationship with NSCLC development is unclear and thus needs to be investigated.
Methods: AMPKα1-knockout and mutant cell lines that simulate AMPKα1 succinylated and desuccinylated at K266 were generated via CRISPR/Cas9 and site-directed mutagenesis technology. The effects of AMPKα1 succinylation at K266 on the proliferation, apoptosis and lipid metabolism of NSCLC cells were also analysed. The role of succinyltransferases and desuccinylases in regulating AMPKα1 succinylation at K266 was analysed by immunoprecipitation and in vitro catalytic experiments. The effects of AMPKα1 succinylation on lipid metabolism and the AMPKα1 ubiquitination level were also analysed. The relationship between AMPKα1 succinylation at K266 and NSCLC development was analysed via immunohistochemistry.
Results: The expression levelsof AMPKα1 and AMPKα1 succinylated at K266 were higher in NSCLC tissues, which promoted the growth of NSCLC. The 5-year overall survival rate of the group with high levels of AMPKα1 succinylated at K266 was lower than that of the group with low levels of succinylation at K266, and the succinylation levels were associated with the T (P=0.024), N (P=0.018), and TNM stages (P=0.024) in NSCLC patients. HAT1 and SIRT5 can interact with AMPKα1 and participate in the regulation of AMPKα1 succinylation at K266. The succinylation of AMPKα1 at K266 regulates lipid metabolism, and this process can lead to a decrease in AMPKα1 ubiquitination.
Conclusion:
AMPKα1 succinylation at K266 inhibits the ubiquitination-mediated degradation of AMPKα1, which increases the stability of this protein, enhances lipid metabolism, and promotes the growth of NSCLC cells. These findings have clinical diagnostic value for NSCLC and provide important clues for understanding the occurrence and development of NSCLC.
Kumap: Kernel Uniform Manifold Approximation and Projection for Out-of-sample Extensions Problem
Authors: Ran Ruisheng , Li Benchao , Zou Yun
Published: January 2024

Uniform Manifold Approximation and Projection (UMAP) is a popular dimensionality reduction and visualization algorithm recently proposed and widely used in several fields. However, UMAP encounters difficulties in mapping new samples into low-dimensional embeddings with what has been learnt from the learning process, which often referred to as the out-of-sample problem. In this paper, a kernel UMAP (KUMAP) method is proposed to address this problem, which is a kernel-based expansion technique. It uses the Laplacian kernel function to map the original samples to the low-dimensional space. In addition, to make full use of the label information in the sample data, a supervised kernel UMAP (SKUMAP) is also proposed. The KUMAP and SKUMAP methods are evaluated on different scale datasets in terms of the preservation of structure in small neighborhood data, silhouette coefficients, and classification accuracy. Compared with UMAP and other representative method, the KUMAP and SKUMAP methods have better embedding quality, higher classification accuracy, and better visualization.

The spatial distribution of Qingyan Ancient Town and its military wisdom are studied using Thiessen polygons, fractal theory and complex networks methods with Qingyan Ancient Town as the object of study, in order to clarify the characteristics of the architectural layout of the military-type ancient towns in southwest China since the Ming Dynasty. The results show that the architectural spaces of the six districts of Qingyan Ancient Town have good self-similarity and complexity, the architectural space forms of the six districts are mainly influenced by the natural geomorphology, all of them are agglomerated and distributed, and their architectural space layout form structure and function are consistent. Besides, the functional variability of the building space will have an impact on the connectivity characteristics of the building network, the greater the density of the building space network, the greater the network degree centrality potential, the more uneven the distribution of nodes, the more obvious the centripetal tendency, the better the network connectivity. The architectural network of Qingyan Ancient Town is characterised by low vulnerability, good stability and strong connectivity, reflecting the wisdom of the architectural layout within Qingyan Ancient Town, which is based on the military connectivity function of efficient and close cooperation of the inhabitants, taking into account the economic trade and cultural life, thus forming a complete military Tunpu small society. Second, the functional difference of subjectivity leads to the connectivity of architectural spatial network with hierarchical and graded characteristics, and the natural factors, human factors and social system factors of traditional villages, ancient towns and ancient settlement sites in southwest China affect the connectivity of architectural spatial network, the connectivity of the architectural spatial network of traditional settlements signifies the intrinsic laws of nature and society, and connectivity can characterise the laws of the natural and social environment in which traditional settlements were created. Finally, this study can provide a scientific reference for the conservation planning, design and construction management of military Tunpu ancient towns.

Authors: Jiao Liuyang , Yao Jianan
Published: January 2024

In the development research of sports, predicting performance is a crucial task. Through scientific prediction methods, athletes can be better guided to train and develop scientific training plans. At present, the prediction of sports performance mainly relies on expert experience, and its accuracy is relatively low. Based on this, in order to address the challenge of large-scale data, we propose an Olympic performance prediction system based on genetic algorithm and related facial expression recognition technology. The system utilizes the self-organization, adaptability, and intelligence of genetic algorithm, with the main goal of improving search efficiency. After multiple comparative experiments, the algorithm proposed in this article shows higher accuracy in feature selection of multidimensional data, almost surpassing the level of all other algorithms. In order to improve the overall running speed of the system, parallel processing technology was adopted. The results showed that our designed system demonstrated excellent performance advantages in both user connection count and HTTP connection count testing, providing support for in-depth research on Olympic performance and expanding competitive sports. At the same time, it also improved the accuracy of Olympic performance prediction and provided data support.

MKARE®, a 100% natural ingredient derived from fresh eggshell membrane (ESM), has a rich composition in bioactive compounds like collagen, hyaluronic acid, and elastin. These components are beneficial for managing osteoarthritis (OA) due to their anti-inflammatory and regenerative properties. Highlighting the significance of freshness, our research has shown that the effectiveness of MKARE® is higher than that of other commercial products based on ESM that have been stored for several days at room temperature, losing their bioactive compounds. This study explores the MKARE® anti-inflammatory capacity through an in vitro and clinical analyses, demonstrating its ability to alleviate OA symptoms and improve joint health. This underscores the crucial role of freshness in optimizing the therapeutic benefits.
Extended Storage of Cut Flowers Using Sub-zero Temperature
Authors: Kalinowski Jennifer , Dole John M.
Published: January 2024

The cut flower industry needs postharvest techniques that allow for extended storage of fresh cut flowers to meet consumer demands. We compared the use of a sub-zero storage temperature (−0.6 °C) to maintain viable flowers with improved or comparable vase life to flowers stored at the industry standard (4 °C). The vase life of 17 commercially important cut flower species, alstroemeria (Alstroemeria), anemone (Anemone coronaria), campanula (Campanula medium), carnation (Dianthus caryophyllus), chrysanthemum (Chrysanthemum), delphinium (Delphinium elatum), freesia (Freesia), gerbera (Gerbera jamesonii), gypsophila (Gypsophila paniculata), larkspur (Consolida), lily (Lilium), lisianthus (Eustoma grandiflorum), ranunculus (Ranunculus asiaticus), rose (Rosa hybrida), stock (Matthiola incana), sunflower (Helianthus annuus), and tuberose (Polianthes tuberosa), when stored dry at −0.6 °C for durations of 4, 8, and 12 weeks was comparable to or longer than that when stored at 4 °C. Tuberose stems were not viable after holding for any storage duration or temperature. Experiment 2 compared the use of a prestorage pulsing treatment of water, hydrating solution, or holding solution containing carbohydrates for 8 hours before extended storage for carnation, chrysanthemum, delphinium, lily, and rose stems. Stems of carnation benefitted from pulsing with a hydrating solution and maintained vase life similar to that of nonstored control stems when stored for 4 weeks at −0.6 °C. Conversely, rose stems only maintained vase life similar to that of nonstored control stems when held at 4 °C for all pulsing solutions. Lily and chrysanthemum stems had a decline in vase life with all pulsing solutions and only remained viable after 8 weeks of storage when held at −0.6 °C. Additionally, stored chrysanthemum and lily stems had a longer vase life when stored at −0.6 °C than that when held at 4 °C after 4 and 8 weeks of storage, respectively, with all pulsing solutions. Delphinium stems were not viable after any storage duration. Experiment 3 further evaluated carnation, lily, and rose stems with and without a prestorage acclimation period at 4 °C for either 24 hours or 1 week before extended storage of 4, 6, or 8 weeks. Holding stems at 4 °C for 1 week before extended storage reduced the vase life of all species. Rose stems remained viable after 8 weeks of extended storage when held at −0.6 °C, but only when no prestorage hold was used. Lily and rose stems were not viable beyond 4-week storage durations when held at 4 °C, but they remained viable with no prestorage holding period after 8 weeks at −0.6 °C. Carnation stems maintained a longer vase life irrespective of a prestorage holding period when stored at −0.6 °C. Through this analysis, we showed that many species of cut flowers may be held at a sub-zero temperature with vase life better than or comparable to that with the industry standard of 4 °C.

Published: January 2024

The purpose of the study is to present the research results of the capabilities of modern portable rapid X-ray fluorescence analyzers when solving problems of geological and geochemical prospecting. On example of the applied SciAps X200 analyzer, the metrological indicators for the analysis results by portable instruments have been studied. The accuracy assessment results of analytical studies according to state standard reference samples are shown. Reproducibility of the analysis results is calculated on the basis of samples from promising gold sites of the Bodaibo synclinorium. The method is proved to be of high precision, and measurement errors in many cases are many times lower than the permissible certified values. The reproducibility is shown as 0,5–20 % depending on the element, which in most cases is significantly lower than the methodology permits. The results of interlaboratory comparative tests confirming the comparability of the analytical results of stationary and portable X-ray fluorescence analyzers are presented. For a number of significant elements, the authors have substantiated the lack of need to refine the results of the field rapid X-ray fluorescence analysis using labor-intensive and expensive methods with acid decomposition - atomic emission and atomic absorption spectroscopy. It has been proved that introduction of portable express equipment into geological prospecting works will make it possible to conduct real-time “on site” analytical studies.

The purpose of the present research is to provide a comprehensive analysis of data on the geological and physical properties of formations and the fluids saturating them in the Volga-Ural oil and gas province using the methods of geological and statistical model ranking. The discriminant analysis conducted on the basis of qualitative criteria (reservoir type and stratigraphic confinement) identified in all cases the zones of uncertainty, which affect the effectiveness of managerial decision-making in the conditions of analog objects. On this score, the results for six models were refined and updated according to the principle of rank uniqueness value calculation by three methods, both for each model individually and for model systems while using them within the obtained distributions of objects in the axes of canonical discriminant functions. Theoretical and practical recommendations were given regarding the use of geological and statistical models in the development of Volga-Ural oil and gas province fields. The results obtained can be used to solve a wide range of practical problems of proactive resource management, which enable effective determination of the best strategy for the successful extraction of residual and hard-to-recover oil reserves. The proposed parameter ranking table allows both to determine the most unstable parameters with a high degree of probability and to level the factor of heterogeneity and disequilibrium of field data. The conducted study established that identification of object association with a particular group in the axes of canonical discriminant functions leads to the formation of the zone of uncertainty. The latter increases the risks of making ineffective managerial decisions when developing different categories of subsoil users’ assets. Using the methods of ranking geological and statistical models, an algorithm for constructing a hierarchical system is proposed, which allows to expand the application field of the results of geological and statistical modeling in the oil and gas industry as well as to reduce the risk of nonrepresentative results.

The Senegalese education system has in its system a body responsible for the control, management and planning of education. This inspection body is trained at FASTEF. The training plan is dynamic and has changed a lot in terms of content relating to the profile of inspectors needed by the system. However, some aspects of the training, including the internship report, have changed very little in terms of their content and their importance in the dynamics of communication and interaction between the practice settings and the University. This communication focuses on the understanding of practices and the evaluative arrangements perceived through the internship reports of student inspectors. Our conceptual framework is based on a socioconstructivist and systemic approach inspired by Bronfenbrenners theory of human ecological development (1979, 2000, 2004). The choice of such an approach makes it possible to identify and describe the interactions between the individual and his environment. Bronfenbrenner situates these interactions of concentric structures at four levels: microsystem, mesosystem, exosystem and macrosystem. In an approach combining documentary analysis, use of individual interviews and open questionnaires, we were able to identify, among other elements: 1) the relationships of the actors based on a kind of moral contract anticipating future situations 2) a descriptive structure of the internship reports 3) a weakness in the exploitation of the contents of the reports. Also, the development of reflective practice among inspectors in internship situations, the development of pragmatic perspectives are real challenges for FASTEF.

Soil is one of the most varied environments for microbial biodiversity including deuteromycetes. The fungal population is maximum close to the soil surface and reduced with soil depth. Inorganic matter and aeration are limiting factors for fungal growth. Cultivated soils contain many organisms in common, but cultivation may change the proportion of different species of soil fungi. Deuteromycetes are microscopic organisms that grow in long threadlike structures called hyphae, which are branched and septate. They are either saprophytic or parasitic. Deuteromycetes hold great economic importance as they act as decomposers of organic matter and play an important role in mineral recycling. They are known as second class fungi or fungi imperfecti because they do not reproduce sexually. Deuteromycetes are accountable for various plant diseases and cause a shortage of food. Climate of the Gondia district is tropical hot and favorable for the growth of fungi with suitable soil for rice cropping. Altogether biodiversity of 33 species of deuteromycetes belonging to 12 genera was recorded through the study from rice field soil.

Introduction. Multiple myeloma (MM) accounts for 1% of all cancers and about 10% of all hematological malignancies. Although there are many types of current therapeutic approaches, MM still remains an incurable disease, which points to the need for improvement of the management of patients with this disease in real-world clinical settings.

Aim. To analyze the actual practice of treating Russian patients with multiple myeloma (MM).

Materials and methods. A multicenter observational retrospective study was conducted. The final analysis included data from 268 patients with the diagnosis code C 90.0, C90.1, C 90.2, C 90.3 ICD-10, aged ≥ 18 years, treated and monitored in 3 Russian centers.

Results. 31.7% of patients had bone and/or extramedullary plasmacytomas. According to Durie Salmon, there were patients with stage III (56.1%) prevailed in ISS - with stage II (41.8%). Cytogenetic studies were performed only in 5.2% of patients. Patients most often encountered diseases of the cardiovascular system (43.3%), kidneys (14.7%), endocrine system (13.1%). The average number of days of hospitalization is about 41.9 days per calendar year. In the first line, 90% of patients received bortezomib-based regimens, 15.8% received high-dose chemotherapy with autologous hematopoietic stem cell transplantation. 66.7% of first-line patients responded to treatment. In the 2nd line, the most commonly prescribed regimen was Rd (lenalidomide with dexamethasone (26.83%), bortezomib-based regimens (24.39%), regimens with the inclusion of new agents (daratumumab, ixazomib, carfilzomib) (17.07%) 40.82% patients responded to treatment.Three-line regimens were dominated by chemotherapy (29.73%) and with the inclusion of new agents (daratumumab, pomalidomide, carfilzomib) (27.03%), 39.3% responded to treatment.

Conclusion. Optimization of therapy for patients with MM and the need to improve approaches to the treatment of this disease remains a significant problem in the modern healthcare system. The results of the management and treatment of patients in real practice is of decisive importance for the choice of the most effective methods of therapy.

The issue of the development of hydrocarbon deposits in the Arctic zone belongs to the category of strategic and urgent. Its solution, in fact, is the use of a chance, the implementation of which would allow to overcome the single-industry specialization of the country, reduce the degree of raw materials orientation and solve structural and technological problems to restore the industrial subsystem. Overcoming these difficulties can be accomplished by revaluing the institutions of post-reform Russia and adjusting them in terms of the synthesis of commercial and statistic approaches to industrial policy. The institutional way of research is new (although it currently has wide variability). The authors, in the form of a worker, chose a statement by L. Thévenot regarding the theory of agreements, which states the presence of seven subsystems (“worlds”) in society that participants in economic transactions encounter. In this context, the purpose of the study is to modernize the management model of the Arctic zone, taking into account both the traditions of institutionalism with its ideas about the strong influence of management institutions on the economy, and the directions of new institutionalism with its theory of agreements. At the same time, as a hypothesis, it is noted that achieving the goal involves analyzing the control object taking into account its basic characteristics, reflecting the real fundamental principle in a specific subsystem. The institutional method of research makes it substantively to answer the question of the role of the state in industrial policy: to determine the nature of the model and the degree of intervention, taking into account the features of the functionality of the management object, its belonging to a certain subsystem, role, geopolitical significance, cycle duration and degree of fusion with other participants in inter-economic relations. According to the theory of agreements, the Arctic zone (as well as other regions of the Far North), according to the authors, belongs to the number of management objects that are organically poorly compatible with universal norms of market behavior. Based on the nature of economic relations in the Arctic zone, we note that subsystems of industrial, ecological, traditional and creative activities are immanent for it. Conclusions are drawn that the provisions of the theory of agreements are a convincing argument for an institutional view of the Arctic zone. Therefore, the solution of the issue of transformation of the economic model of the development of hydrocarbon deposits in the Arctic zone in the context of the proposed synthesis of commercial and statistic approaches is of particular importance.

The study was conducted to determine the frequency of autoimmune haemolytic anaemia in non-Hodgkin’s lymphomas. A cross sectional study on 100 patients of Non-Hodgkin Lymphoma was conducted in Pathology department, KEMU, Lahore.  The mean age among the patients was 50.14 ±17.053 years. The mean haemoglobin was 10.73g/dl ± 2.74 . Out of 100, 88 patients had Coomb’s Test negative and 12 patients had a positive result. Those having a positive coomb’s test showed a higher retic count i.e., 5.05 ± 2.37. The average bilirubin levels in all NHL patients were 0.901 0.995 mg/dL, with a substantially higher mean of 2.15 1.19 mg/dL among patients who tested positive for Coomb's. The LDH levels of those immensely high 764.5 ± 441.Post stratification chi square testing showed no significant relationship was found between autoimmune hemolytic anemia among NHL patients. Age and gender have no significant effect. However, disease stage can be a risk factor. Therefore, it is emphasized that all patients of NHL, regardless of age and gender, must be thoroughly investigated.

The research aims to find out the reusability of jute stick charcoal (JSC) to remove Remazol Red (RR) from textile effluents. The JSC was characterized by scanning electron microscopy (SEM), energy-dispersive X-ray (EDX) spectroscopy, and Fourier-transform infrared (FTIR) spectroscopy to analyze the morphology, functional groups, and chemical composition, respectively. The batch adsorption method was applied in this study, and it disclosed that dye uptake depends on various factors, namely, pH, contact time, adsorbent dose, and dye concentration. Notably, 93.12% of the dye was removed with the best removal efficiency at a pH of 1, an adsorbent dose of 0.6 g, and an equilibrium time of 120 min, where the adsorption occurred rapidly in the first 20 min. The Langmuir isotherm model successfully defined the adsorption phenomena, yielding an R2 value of 0.995. The kinetic experimental data followed the pseudo-second-order model (R2 = 0.999). The optimum adsorption parameters were implemented for the effluent obtained from a dye bath where a fabric sample (5 g) was dyed with RR, and 62.4% dye was removed. For the scaled application of JSC to a wastewater stream, the raw textile effluent was also treated, which resulted in 52.6% of dye removal. These results show that JSC is a promising adsorbent for treating textile wastewater.
Analytical solution of heat equation taking into account convection with isothermal boundary conditions
Authors: Ganopolskij Rodion M.
Published: January 2024

The problem of determining the distribution of heat through the reservoir constantly arises in the production of hydrocarbons. Changes of temperature affect the viscosity of oil and consequently the rate of its production. Taking into account the filtration process, additional terms appear in the classical heat conduction equation, including nonlinear ones. Various numerical schemes are used to solve the modified equations. The question of the convergence of such methods often arises. The task of this work is to obtain an analytical solution of the heat equation in cases where it is possible, in order to further compare numerical solutions with them.

Background::

Multisystem information, including musculoskeletal information, can be captured from chest CT scans of patients with COVID-19 without further
examination.

Aims::

This study aims to assess the relationship between chest CT-extracted baseline bone mineral density (BMD) and body composition parameters and
the length of hospital stay in these patients.

Methods::

A retrospective analysis was performed in a cohort of 88 patients with COVID-19. Correlation analysis and a generalized linear model (GLM)
were used to assess the associations between the length of hospital stay and covariates, including age, sex, body mass index (BMI), BMD and body
composition variables.

Results::

The mean length of hospital stay was 27.4±8.7 days. The length of hospital stay was significantly positively associated with age (r=0.202, p=0.046)
and the paraspinal muscle fat ratio (r=0.246, p=0.021). The GLM involving age, sex, BMD, paraspinal muscle fat ratio, subcutaneous adipose
tissue (SAT) area, visceral adipose tissue (VAT) area, and liver fat fraction (LFF) showed that the length of hospital stay was positively correlated
with VAT area (β coefficients, 95% CI: 9.304, 1.141-17.478, p=0.025).

Conclusion::

The musculoskeletal features extracted from chest CT correlated with the prognosis of COVID-19 patients. Factors including old age, a higher
paraspinal muscle fat ratio and a larger VAT area in patients with COVID-19 were associated with longer hospital stays.
