Neonatal screening
Authors: Pàmpols Teresa
Published: April 2024

Neonatal screening (NS) is a medical act in the context of preventive medicine aimed at the early identification of infants affected by certain conditions that threaten their life and long-term health, for which a timely intervention can lead to a significant reduction of morbidity, mortality and associated disabilities. It emerged three decades ago in the context of prevention of mental retardation. Since then, around 600 inborn metabolic disorders have been described and technological progress has been impressive; nevertheless only around 5% of the disorders have been the object of NS. The most frequently cited reasons for the limitation are low prevalence and the lack of treatment. The tandem mass spectrometry has come in place in recent years across the globe, expanding NS to include several disorders of intermediary metabolism. This has shown, in addition to a prevalence much higher than previously thought, the benefits of early detection. The present work is a review of NS, not only from the point of view of technological/medical achievements, but also considering other factors which will affect specific disease selection, according to the social and organizational infrastructure that may expand the borders of NS.

Published: April 2024

Pleural empyema is defined as the pyogenic infection of the pleural space with purulent effusion. Although it is frequently seen in children and therapy protocols have been developed for it, there are only a few reports about pleural empyema in newborn infants. To our knowledge, just one preterm infant has been reported in the literature. In this article, we report an male infant born at 29 weeks of gestation who had pleural empyema on the 53rd day of life. Multidrug-resistant Pseudomonas aeruginosa (P. aeruginosa) was isolated from his pleural fluid culture. We suggest that this is the first preterm infant with P. aeruginosa empyema.

Published: April 2024

This study aims to discuss the acoustic profile of Deli Malay Language (Bahasa Melayu Deli) vowels from phonetics. In collecting data, the research will involve 15 DML native speakers. The speakers involved were between 20-40 years old. The data was obtained by recording the speaker’s voice in a quiet room with a consistent microphone distance of about 30 centimeters from the lips. Teak speakers will read syllable words containing target vowels in sentences with DML vowels. The pronunciation target vowel is placed on the first syllable. This study found that Deli Malay has seven vowels, namely vowels /i/, /e/, /ə/, /a/, /o/, /u/ and /ↄ/. DML vowel positions /i/ and /e/are high and medium front vowels. While the vowels /o/, /u/ and /ↄ/ are high and medium back vowels. Meanwhile, the vowels /a/ and / ə / are mid and low mid vowels. Later, this acoustic study calculated approximate vowel measurements based on F1 and F2 from the spectrogram at Praat. The measurement of the sound quality of forman vowels in Malay deli vowels is vowel /a/ F1 = 876 Hz and F2 = 1701 Hz vowel /i/ F1 = 533 Hz and F2 = 2328 Hz, vowel /e/ F1 = 689 Hz and F2 = 2204 Hz, vowels / ə/ F1= 692 Hz and F2= 1686 Hz, vowels /o/ F1= 650 Hz and F2= 1459 Hz, /ↄ/ F1= 658 Hz and F2= 1373 Hz, and /u/ F1= 524 Hz and F2 = 1383 Hz. This study provides a detailed analysis of the acoustic properties of Deli Malay vowels, contributing to a deeper understanding of the phonetic characteristics of the language.

The Impact of G6PD Deficiency on Liver Function in Children Under 15
Authors: Saeed Saad Mahmood , Ahmed Naji Nazar
Published: April 2024

Glucose-6-phosphate dehydrogenase (G6PD) is involved in the first phase of the pentose phosphate pathway (PPP), entailing the reduction of nicotinamide adenine dinucleotide phosphate (NADP+) and the oxidation of glucose-6-phosphate to 6-phosphogluconolactone. A deficiency in the G6PD activity can result in numerous illnesses, including liver diseases. The first three enzymes in PPP are responsible for the oxidative phase. They make NADPH, which is needed to deal with oxidative stress, especially in people who do not have enough G6PD. The study included (90) samples from people with hemolytic anemia (Favzim) and control to determine the levels of G6PD, albumin, total protein, liver function, alanine transaminase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP) and bilirubin. The results showed that there was a significant decrease (P<0.05) in the serum levels of G6PD in the patients group when compared with the control group. Also, there was a significant increase (P<0.05) in the serum levels of albumin, total protein, ALP, ALT, AST and total bilirubin in patients with the G6PD deficiency when compared with the control group. In addition, this study revealed a strong positive correlation between some biochemical parameters studied, such as:  Total protein with TSB (r2 = 0.897), TSB with ALT (r2 = 0.893), AST with ALT (r2 = 0.623) and total protein with ALT (r2 = 0.804).
Linear Free Surface of Steady and Unsteady Flow Theoretical Study
Authors: AL-Ali Suha Ibrahim , AL-Awsi Nihad Jalal
Published: April 2024

This study investigates the relationship between the crucial cone point in limiting steady and unsteady simulation flows inside a simple two-dimensional, vertical sand column subjected to water withdrawal. The analysis employs a versatile technique applicable to both linear steady and linear unsteady problems. By utilizing Fourier series techniques, the method finds the solution for a line sink in a vertical duct and extends the steady technique to achieve unsteady solutions. The evolution of the beneath-the-water table surface towards steady states is monitored when they exist. The key findings highlight that as the impermeable base moves further away, the distance between the interface and the sink increases. With increasing flow rates, the critical depth elevates; however, a minor decrease in the critical flow rate is observed when the sink approaches the base. The prior behaviour of the flow impacts the critical flow rate value for each interface height. The study provides steady and unsteady solutions, employing linearized formulations, which demonstrate good agreement with observed phenomena. The length scale of the spatial separation between the interface and the sink emerges as a critical factor in determining cone. These findings contribute to a better understanding of cone phenomena and emphasize the significance of considering specific dimensions in the analysis of flow dynamics within porous media.
Genotyping of Methicillin Resistant Staphylococcus aureus Clinical Isolates in Sulaimani City using Pulsed -Field Gel Electrophoresis
Authors: Naji Dunya Emad , Arif Sehand Kamaluldeen
Published: April 2024

Methicillin-resistant Staphylococcus aureus (MRSA) strains cause serious nosocomial infections. The objective of this study was to detect and find the epidemiological relatedness among MRSA isolates which was collected in Emergency burn-and-plastic surgery hospital in Sulaimani city using Pulsed-filed gel electrophoresis (PFGE). Routine methods were used for detection of Staphylococcus aureus, further molecular confirmation was done by PCR assays targeting 16S rRNA gene. The cefoxitin-disc diffusion assay was used for detection MRSA, which is subsequently confirmed by the presence of the mecA gene. PFGE was chosen to observe the genetic relatedness of 10 MRSA strains using SmaI restriction endonuclease. All the isolates (100%, 50/50) carried 16S rRNA gene specific for S.aureus and (42%, 21/50) exhibited resistance to cefoxitin and harboured the mecA gene, thereby being classified as MRSA. Among 10 MRSA isolates, the PFGE pattern were grouped into four clusters. Three isolates belonging to cluster (C3) were indistinguishable, 4 isolates belonging to cluster (C4) were closely related, 2 isolates of the second cluster (C2) were possibly related and the first cluster (C1) with 1 MRSA isolate was unrelated. This finding shows 30% of the samples had indistinguishable fingerprints with no changes in banding profiles, while 40% of the samples had closely related patterns. PFGE is a good discriminatory tool for typing MRSA strains.

This paper proposed OMR by using Modify Bidirectional Associative Memory (MBAM), MBAM has two phases (learning and analysis phases), it will learn on the answer sheets that contain the correct answers by giving its own code that represents the number of correct answers, then detection marks from answer sheets by using analysis phase. This proposal will be able to detect no selection or select more than one choice, in addition, using MBAM make it timeless because it will deal with a complete answer sheet, it no need to extract the answer boxes from the answers sheet. The proposed OMR exhibits accuracy is 99.998% in the recognition of marked and non-marked.
Dolomitization of the Lower Part of the Sargelu Formation, Northeastern Iraq
Authors: Muhammad Shwan A. , Saeed Azad T.
Published: April 2024

The prominent characteristic of the lower part of the Sargelu Formation of the Middle Jurassic is the occurrence of destructive dolomitization. This dolomitized unit, cropped out in the high folded and Imbricated zones in Northern Iraq, is situated in the Gotnia Basin and has been distinctly identified and are documented in previous studies. Dolomite crystals are euhedral in shape; hence, they are classified as saccharoidal dolomite, resulting in the elimination of all biocontent and the destruction of the original rock fabrics. Despite the abundance of intercrystalline pores in this unit and their role in the quality of reservoirs in the oil fields, the origin or mechanism of dolomitization is not well understood yet. The aim of this investigation is to find out a suitable model for the dolomitization and to propose possible mechanisms that led to the dolomitization. At the top of the Lower Jurassic Sehkaniyan Formation, an extensive mass of destructive dolomitization has also occurred. The dolomitic unit of the Sargelu Formation, which extends for hundred kilometers constantly. Stratigraphic correlation reveals that the Sargelu Formation is juxtaposed with different successions, such as the Alan and Sehkaniyan formations, that show evidence about peritidal and sabkha environments, where the dolomitization units were associated with solution collapse breccia and microbial stromatolite. This study proposes that the reflux and burial dolomitization models for the lower part of the Sargelu Formation by comparing the paleoenvironmental conditions of the late Lower Jurassic and early Middle Jurassic in the Gotnia basin with a modern analogue model.

Authors: Abdulhameed Shapol Shwan , Shingaly Waleed S.
Published: April 2024

Shiranish Formation in both Smaquli and Rawanduz sections is composed of an alternation of marly limestones, limestone and marl beds with fissile shale beds. Depend on color, lithology and other sedimentological criteria during field observations of the studied sections, the Shiranish Formation is divided lithologically into lower, middle and upper units. Planktonic Foraminiferal Lime Mudstone Microfacies (Shf1), Lime Wackestone (Shf2) and Planktonic Foraminiferal Lime Packstone Microfacies (Shf3) have been defined as three distinct microfacies with four submicrofacies ((Keeled Planktonic Foraminiferal Lime Wackestone submicrofacies (Shf2b), Globular Chamber Planktonic Foraminiferal Lime Wackestone submicrofacies (Shf2a), Bioclastic Lime Wackestone submicrofacies (Shf2c), Planktonic Foraminiferal Lime Wackestone submicrofacies (Shf2d)). The major microfacies in both sections was lime wackestone which is dominated in middle and upper units in both sections. Sedimentological and paleontological evidences suggest that the Formation was deposited in the outer shelf setting and progressed to the upper bathyal setting, in addition to that the microfacies changed from packstone to mudstone meaning deeping upward sequence.

Published: April 2024

Image de-noising and restoration represent basic problems in image processing with many different applications including engineering, reconstruction of missing data during their transmission and enhancement ..etc. this work is aimed at developing effective algorithm for denoising image using new strategy algorithm of wavelet techniques ,by applying two dimensions wavelet transform using Haar wavelet. Wavelets are hierarchically decomposing mathematical tools.  A noisy picture is sent to the Haar wavelet transform to create four decomposed bands(for each level), and the noise is then removed by applying a threshold to the resultant image band. Then, an inverse transform is used to provide a noise-reduced picture. Performance characteristics are improved by the suggested design in contrast to those of the current approaches.

Published: April 2024

Three different new designs of an objective pinhole lens were compared. Their magnetic and optical properties were studied using Finite Element Method for Calculating Magnetic Field Distribution (FEM-CMFD) and Magnetic Electron Lens Optical Properties (MELOP) software. The focal length (fo), spherical aberration (Cs), chromatic aberration (Cc), and the resolving power (δ) of each lens were compared at a range of relatively corrected acceleration voltages (Vr = 100 V-100 kV) and a constant excitation of (NI = 5280 A-t (where A represents Ampere and t represents turn)) and current density (2 A/mm2) to find the best design. The L1 lens is similar to the Gemini lens. L2 and L3 are the traditional pinhole lens shape. The L1 lens gave the best results in terms of optical and magnetic properties as its optical properties at medium and low acceleration voltages. L2 and L3 Lenses had almost identical magnetic properties, but the difference was apparent in optical properties.

This study was conducted in the laboratories of the Biology Department - College of Science - Tikrit University, the laboratories of the Food Science Department - College of Agriculture - University of Anbar, and the Public Health Laboratories - Anbar for the period from December 2021 AD until February 2022 AD,  study involved taking samples from hospitalized COVID-19 patients of both sexes, after a confirmed positive PCR test result. As well as those lying in quarantine in three Iraqi governorates (the isolation unit in Karkh, Yarmouk and Kadhimiya hospitals, the Al-Shifa quarry hospital in Anbar, the public health laboratory in Anbar, and the quarantine hospital for thousands in Erbil), in addition to outpatient clinics. They were distributed by 30 patients and 20 healthy subjects from each governorate, with ages ranging from 18-80 years, randomly to men and women in order to determine the role of genetic polymorphisms in the ACE inhibitor gene in the study samples. The results of the genetic polymorphisms of ACE-1rs4646994, ACE-2rs2106809, and ACE-2rs4240157 showed that there were non-significant differences between the frequency of alleles and genotypes in the patient's group compared with the healthy group. The DD mutant genotype of ACE-1rs4646994 appeared in the patient's group in Baghdad and Anbar with a high percentage, while patients in Erbil showed the highest percentage of the heterozygous genotype ID compared to healthy subjects, with an OR= 0.922, OR= 2.750, and OR= 1.118, respectively, for the mutant allele D. Therefore, it is not considered a risk factor for the disease in Baghdad, in contrast to Anbar and Erbil. The polymorphism of ACE-2rs2106809, the homozygous genotype CC was dominant in patients in the aforementioned provinces and may not be considered a risk factor for the disease. The results of ACE-2rs4240157 gene polymorphism, the heterozygous CT genotype showed a high percentage in patients in Baghdad and, while in Anbar patients, the normal genotype TT appeared to be the highest percentage compared to healthy subjects. The C mutant allele in Baghdad, Anbar, and Erbil patients reached OR= 1.306, OR= 4.333, and OR= 9.00, respectively, so this allele is considered a risk factor for the disease. We can conclude from this study the role of each of the polymorphisms rs4646994 ACE-1 and rs4240157 ACE-2 in infection with COVID-19 and the severity of its symptoms according to the geographical region and race, in contrast to rs2106809 ACE-2, as it is possible to conduct clinical studies to demonstrate the role of genetic polymorphisms with Relationship to diseases depending on the region and race.

Published: April 2024

Energy from renewable sources has developed significantly in the past few decades. Photovoltaics have played a crucial role in the technology employed to generate this type of energy. Technicians and researchers can benefit from systems that offer knowledge and data on the efficiency and performance of solar cells. In this work the I-V characteristic of photovoltaic of silicon was measured, and the influence of different n-type thicknesses was examined with their different doping concentration; this has been done by PC1D simulation, It would be appropriate for developing silicon single-layer without cost. The n-layer thickness and n-region doping are the factors responsible for a solar cell's efficiency and performance. In this context silicon is the ideal candidate due to the swift increase in their efficiency, and its dependability and stability. In the end, to draw a conclusion around the ideal parameters that a good solar cell has to have, the optimum external quantum efficiencies obtained from this design were (87.71 %) for mono layer front surfaces. The results from these simulation studies prove that it is possible to propose these design parameters for mono layer solar cell fabrication. By adjusting the effectively mentioned parameters, a great efficient and I-V characteristic solar cell has been achieved.

Authors: Hashim Ansam Adnan , Jamei Rashid
Published: April 2024

This paper seeks to synthesize antibacterial green polymeric composites utilizing extracted cellulose, a natural polymer sourced from biomass. The cellulose was obtained from local agricultural waste. Subsequently, the polymeric composites were synthesized, incorporating blends of nano zinc oxide and nano titanium dioxide in varying proportions. All synthesized samples undergo comprehensive characterization and examination through a range of tests encompassing structural and thermal testes. Furthermore, the antibacterial activity of the samples was assessed using the disc diffusion method, enabling the identification of the most effective formulations. The ultimate selection of the optimal composite was based on the collective outcomes of all tests, facilitating its potential utilization across diverse applications. In conclusion, the Albizia tree demonstrates a notable potential for efficient cellulose extraction, making it a viable candidate for such purposes.  The cellulose extracted from Albizia tree holds the capability to yield methylcellulose. The bacterial activity assessment of Nano materials highlighted a distinct efficacy in the case of the 75% Nano TiO2 and 25% Nano ZnO mixture. However, it is worth noting that an excessive increment in Nano ZnO content exhibited adverse effects. Thorough thermal analyses verified the thermal stability of methylcellulose.
Efficient economic energy scheduling in smart cities using distributed energy resources
Authors: Manzoor Awais , Akram Waseem , Judge Malik Ali , Khan Naveed , Khattak Hasan Ali
Published: April 2024

Machine learning provides a powerful mechanism to enhance the capabilities of the next generation of smart cities. Whether healthcare monitoring, building automation, energy management, or traffic management, use cases of capability enhancement using machine learning have been significant in recent years. This paper proposes a modeling approach for scheduling energy consumption within smart homes based on a non-dominated sorting genetic algorithm (NSGA). Distributed energy management plays a significant role in reducing energy consumption and carbon emissions as compared to centralized energy generation. Multiple energy consumers can schedule energy-consuming household tasks using home energy management systems in coordination to reduce economic costs and greenhouse gas emissions. In this work, such a home energy management system is used to collect energy price data from the electricity company via an embedded device-enabled smart meter and schedule energy consumption tasks based on this data. We schedule daily power consumption tasks using a multiobjective optimization method that considers environmental and economic sustainability. Two conflicting objectives are minimizing daily energy costs and reducing carbon dioxide emissions. Based on electricity tariffs, CO2 intensity, and the window of time during which electricity is consumed, energy consumption tasks involving distributed energy resources (DERs) and electricity consumption are scheduled. The proposed model is implemented in a model smart building consisting of 30 homes under 3 pricing schemes. The energy demand is spread out across a 24-hour period for points A2–A4 under CPP-PDC, which produces a more flattened curve than point A1. There are competing goals between electricity costs and carbon footprints at points B2–B4 under the CPP-PDC, where electricity demand is set between 20:00 and 0:00. Power grids’ peak energy demand is comparatively low when scheduling under CPP-PDC for points A5 and B5. Reducing carbon emissions, CPP-PDC reduces the maximum demand for electricity from the grid and the overall demand above the predetermined level. The maximum power demand from the grid is minimized for points A5 and B5, reducing up to 22% compared to A2. The proposed method minimizes both energy costs as well as CO2 emissions. A Pareto curve illustrates the trade-off between cost and CO2 emissions.

Objectives:

Stroke survivors have palliative care needs in multiple domains, which are overlooked. Accurate estimation of these is pivotal in ensuring proper rehabilitation and planning interventions to improve quality of life (QoL). We aimed to assess the palliative care needs of stroke patients in various domains in a structured manner at the neurology service of a tertiary care center in South India.

Materials and Methods:

Seventy-five consecutive stroke patients presenting to the neurology service were recruited over six months with assessment across various domains including symptom burden, physical domain, activities of daily living (ADL), psychiatric/psychological domain, and QoL at baseline and with follow-up at one month and three months.

Results:

Despite improvement in the conventional stroke impairment measures among stroke survivors, there were significant unmet needs across various domains; 98% were severely or entirely dependent on ADL at three-month follow-up; and pain and insomnia were the most frequent (33% incidence) troubling symptoms encountered. There were substantial mental health related issues. The QoL measurement tools employed were the stroke impact assessment questionnaire (SIAQ), a novel tool and the World Health Organization Quality Of Life Brief Version (WHO-QOL-BREF). SIAQ scores at one month showed that 19 patients (42.22%) had their QoL severely affected, and 36 patients (80%) showed the same trend at the three-month follow-up. WHO-BREF scores showed that 27 (62%) did not report good QoL, and 32 (73%) were found not to be satisfied with their health at a one-month follow-up.

Conclusion:

There is a significant burden of unmet palliative care needs among stroke survivors in India across various domains.

Cupping therapy is an alternative treatment that uses a small glass cup to suck the skin with a needle and has been used to manage skin problems and pain. However, serious complications have been reported. Herein, we describe a case of intracranial mycotic aneurysm rupture after cupping therapy.

Case Description:

A 25-year-old male patient presented with a headache and fever after cupping therapy for atopic dermatitis. He was diagnosed with infective endocarditis, and antibiotic therapy was initiated. After that, he suddenly lost consciousness, and head imaging revealed a cerebral hemorrhage due to a ruptured intracranial mycotic aneurysm. He underwent craniotomy, which was successful, and he was transferred to a rehabilitation center with a modified Rankin scale score of 2 at three months post-stroke.

Conclusion:

This case serves as a reminder of life-threatening infectious complication risks after cupping therapy. A patient who has a compromised skin barrier may experience serious adverse effects, especially when cupping is performed without implementing suitable infection prevention measures.

Sokolova Clinical Hospital «RZD-Medicine», Saint Petersburg, Russian Federation S.M. Kirov Militar y Medical Academy Ministr y of Defense of the Russian Federation, St. Petersburg, Russian Federation Relevance. Dislocation of the intraocular lens (IOL) is a serious complication in cataract surgery. Therefore, the search for an effective method of IOL fixation for non-standard surgical situations is still important. Purpose. To analyze clinical results of flanged corneoscleral IOL fixation the technique using polytetrafluoroethylene sutures. Material and methods. The results of surgical treatment of 34 patients (34 eyes) who underwent IOL suturing with suture material made of polytetrafluoroethylene 6-0 (Ecoflon) through the sclera and fixation of flanges in the lumen of corneal paracentesis (Sclerocorneal IOL Fixation Technique) without incisions of the conjunctiva and sclera were analyzed. Results. The average index of maximally corrected visual acuity before surgery was 0.27±0.11. A day after surgery, this parameter increased to 0.41±0.1. One week after surgery, the average index of maximally corrected visual acuity was 0.65±0.1, while the improvement in visual acuity was statistically significantly different from the parameter before surgery and a day after surgery (p<0.05). Conclusion. Application of polytetrafluoroethylene suture material in the ab externo technique, passing through the sclera and fixing the flanges in the lumen of the corneal paracentesis is safe and effective method. As a result, patients had positive visual acuity dynamics with a low frequency of complications.

Purpose. To improve the efficiency and safety of SMILE-type lenticular surgery procedure in correction of different degrees myopia based on the use of low-energy laser parameters. Material and methods. This study includes a comparative analysis of data from 193 patients (288 eyes) operated for different degrees myopia including a number of cases with myopic astigmatism using SMILE technology with different FSL energy levels from 130 to 150 nJ. The parameters were analyzed on the 1st day and after 1 week, 1 month, 3, 6 and 12 months after surgery with assessment of NCVA, quality of life (QIRC questionnaire), general corneal wavefront aberrations (RMS), densitometry and pachymetry. Results. According to visometry, quality of life assessment, RMS, densitometry and pachymetry, the best functional results were obtained in subgroups with mild and moderate myopia on the 1st day after SMILE using an energy level in the range of 130 nJ. And in subgroups with a high degree of myopia, when using an energy level in the range of 140 nJ, no direct effect of energy on other indicators was found. Conclusion. According to the results of the study, it was found that the correction of myopic refractive error using the SMILE technology with a FSL energy level in the range of 130–140 nJ in its effectiveness on the 1st day after surgery exceeds the previously used energy levels (150 nJ) in terms of the quality of restoration of visual functions and does not have a negative effect on other parameters of the cornea.

Review Prospects for the use of nanoparticles (quantum dots) in ophthalmology V.O. Ponomarev, K.A. Tkachenko Eye Microsurger y Ekaterinburg Center, Ekaterinburg, Russian Federation Purpose. A systematic analysis of domestic and foreign literature devoted to the potential use of quantum dots (QD) in ophthalmology, as well as the identification of the main problems regarding the implementation of QD in ophthalmic practice. Material and methods. To carry out the review, a systematic analysis of scientific publications of domestic and foreign authors was carried out on the resources of PubMed, Medline, eLibrary from 2008 to 2021, devoted to the determination of physicochemical parameters, as well as the practical use of QD. Results. QD-based semiconductor nanoparticles are increasingly entrenched in modern science and medicine, in particular ophthalmology. This review defines the main physical parameters and physical and chemical properties of QD. Their potential applications are wide enough and focused on imaging, drug delivery, electrical stimulation and broad spectrum of anti-infective activity. Conclusion. To date, the existing limitations in the sphere of active QD application in ophthalmic practice are related to fundamental research in the field of acute and chronic cytotoxicity, selection of safe doses and concentrations of QD, working out mechanisms of their delivery, as well as in the study of mechanisms of chemical and biological interaction with the structures of the visual analyzer at dynamically changing physical parameters of QD (shape, size, features of functionalization and silanization). Interdisciplinary interactions between the pillars of fundamental medicine, physics, biology, chemistry, and ophthalmology, in particular, will probably allow us to realize in the nearest five years in clinical practice all the fundamental principles laid down in the previous studies.

Получение высококачественных игристых вин является главной задачей виноделия. Одним из основ- ных показателей готового игристого вина являются пенистые свойства, которые зависят от способности исходного вина к пенообразованию. В связи с этим актуально исследование способности сухих белых вин к формированию пены и влияния различных компонентов – белков, фенольных веществ, аминокислот – на этот процесс. Объектами исследования являлись образцы вина, произведенные из винограда сортов Пино блан, Рислинг Рейнский и Шардо- не урожая 2022 года, выращенного в Темрюкском районе Краснодарского края. Способность формирования пены у опытных образцов определяли при помощи «Анализатора пенообразования», разработанного на базе кафедры технологии виноделия и бродильных производств им. профессора Мержаниана КубГТУ. Установлена связь между пенообразующей способностью вина и основными компонентами, влияющими на данный показатель. Проведе- на корреляционная зависимость показателя пенообразующей способности от массовых концентраций белков, фе- нольных веществ и аминокислот. Выявлено, что наибольшим потенциалом к формированию пены обладали вина из сорта Рислинг Рейнский и Шардоне. Полученные данные при дальнейшем исследовании могут быть использованы производителями игристых вин для оптимизации производственных процессов и повышения качества продукции.

Producing high-quality sparkling wines is one of the main tasks of winemaking. One of the main indicators of the finished sparkling wine is its foaming properties, which depend on the ability of the original wine to foam. In this regard, it is important to study the ability of dry white wines to form foam and the influence of various components – proteins, phenolic substances, amino acids – on this process. The objects of the study were samples of wine produced from Pinot Blanc, Rhine Riesling and Chardonnay grapes of the 2022 harvest, grown in the Temryuk region of the Krasnodar Territory. The ability to form foam in prototypes was determined using the «Foaming Analyzer», developed on the basis of the Department of Winemaking and Fermentation Technology named after Professor Merzhanian KubSTU. A connection has been established between the foaming ability of wine and the main components that influence this indicator. The correlation dependence of the foaming ability indicator on the mass concentrations of proteins, phenolic substances and amino acids was carried out. It was revealed that wines from the Rhine Riesling and Chardonnay varieties had the greatest potential for foam formation. The data obtained during further research can be used by manufacturers of sparkling wines to optimize production processes and improve product quality.

Published: April 2024

The purpose of this article is to provide an understanding of possible techniques through which a H1 31.25 kbps Foundation Fieldbus Manchester coded signal can be modulated or demodulated. This understanding will be rendered through MATLAB and SIMULINK models, simulating both ideal and practical as well as noiseless and noisy conditions during the modulation/demodulation process. The simulation models will differentiate between the modulation methods adopted to generate ideal rectangular as well as practical trapezoidal waveforms for the Manchester coded signal. The analysis of the simulation results will describe the mechanisms through which distortion induced by additive white Gaussian noise can be eliminated during the demodulation process either by using recursive filters, such as a Kalman filter, or by calculating wave energy levels in specific time intervals.
