Authors: Birol Egemen , İskender Kerim Tuğşat , Ozkul Timur , Topallı Ayça
Published: October 2024

This study aims to show that a secure, trustable and immutable voting system can be established with Blockchain technology. Decentralized structure of the Blockchain excludes the central authority and provides transparency. Moreover, its cryptographic functions enable secure transactions. Therefore, the operation is prevented from potential frauds, such as multiple votes, fake vote attempts, and fraudulent vote counts. The proposed method, VOTEMAT, covers both electronic voting and paper ballot as a complete solution. A mobile application and a Website, connected to Ethereum private Blockchain network, were developed for the voters who prefer to cast their votes remotely. It is also possible to vote in the voting centres via the mobile device or paper ballot placed in the vote boxes; but these votes are also recorded in the same Blockchain and equally secure. For the remote users, a two-step authentication is designed, based on the information on the national identity card and face recognition. An additional encryption based security measure is used to avoid hacking attempts, such as man in the middle attacks. Since the proposed system is more practical than the traditional voting methods, it can increase the participation and be utilized in all kinds of local or national elections.

Published: October 2024

In this study, the use of three different crown ether-modified electrodes prepared by electropolymerization of different crown ether compounds (CE1, CE2 and CE3) on multi-walled carbon nanotube (MWCNT) modified glassy carbon electrode (GCE) surfaces was investigated for electrochemical dopamine determination. The number of cycles during the electropolymerization of crown ethers and the pH of the buffer solution were optimized. Under optimum conditions, the sensitivities of MWCNT-modified GCE and crown ether-MWCNT-modified electrodes were determined in the range of 4.0×10-6 – 5.7×10-4 M dopamine. The sensitivity of MWCNT/GCE was found to be 6.71 µA mM-1, while the sensitivities of CE1/MWCNT/GCE, CE2/MWCNT/GCE and CE3/MWCNT/GCE were 19.53, 16.32 and 20.80 µA mM-1, respectively. The performance characteristics of the crown ether-MWCNT-modified electrodes such as detection limit, quantification limit, reusability and reproducibility were also investigated. The study showed that crown ether compounds significantly enhanced the electrochemical response in dopamine determination.

Authors: Mert Engin , Dursun Mustafa
Published: October 2024

Permanent magnet synchronous motors (PMSM) can be produced at lower costs with new developments in magnet technology and are widely used in many industrial areas due to their low energy consumption. The widespread use of PMSM brings with it the requirement for high accuracy control performance. In order to achieve high performance accuracy, vector control technique is generally preferred. However, the parameter values of the controllers used in this technique are very important for motor performance. Tuning these parameters by optimization techniques instead of classical methods has become a popular topic. Nowadays, modern control methods show more effective control behavior than classical control methods, which has made the use of modern control methods widespread and studies on modern control methods have intensified.
In this study, the analysis of different optimization algorithms used in the control of an PMSM according to their performance indices is investigated in Matlab-Simulink environment. As a result of simulation with different optimization algorithms under the same conditions, the analysis of optimization algorithms using different performance indices such as integral of the absolute value of the error (IAE), integral of the square of the error (ISE), Integral of the Square of the Error Multiplied by Time (ITSE), and Integral of the Absolute Error Multiplied by Time (ITAE) is carried out.
Investigation of Low Velocity Impact Behavior of Aluminum Honeycomb Sandwich Structures with GFRP Face Sheets by Finite Element Method
Authors: Bozkurt İlyas
Published: October 2024

The aim of this study is to examine the low velocity impact behavior of aluminum honeycomb sandwich structures with glass fiber reinforced plastic (GFRP) face sheets with the help of finite element method. In the study, low velocity impact tests were carried out in the LS DYNA finite element program to examine the effects of face sheets thickness, core number, wall thickness, impact location and impact velocity on maximum contact force, absorbed energy efficiency and damage mode. Progressive damage analysis based on the Hashin damage criterion and the combination of Cohesive Zone Model (CZM) and the bilinear traction-separation law was performed using the MAT-54 material model. At the end of the study, it was determined that the face sheets thickness in sandwich structures had a significant effect on the impact resistance up to a certain impact energy. It has been observed that as the impact velocity gradually increases, there is a decrease in the contact force after a certain threshold value. As the impactor velocity increases, the energy absorption efficiency also increases. It has been determined that the location of the impact is very effective on peak force and energy absorption efficiency. The effect of the number of core layers depends on the face sheets thickness. When the face sheets thickness was not damaged at first contact, the peak force value increased in parallel with the number of layers. It was determined that the dominant damage mode after impact was matrix damage. It has been observed that as the energy level of the impactor increases, damage also occurs on the back surfaces.
Design and Control of Single-Phase Double-Stage PV-MPPT System
Authors: Avcı Emre
Published: October 2024

In the double-stage Photovoltaic-Maximum Power Point Tracking (PV-MPPT) systems, the performance of each stage and the MPPT algorithm may affect the system performance. This study gives the design and control of a single-phase double-stage PV-MPPT system with a cascade controller. For the DC-link voltage control, a classical PI controller is employed. However, double-line frequency harmonic emerges inherently in the DC-link voltage. This voltage harmonic causes a third harmonic in the injected grid current. Therefore, a proportional multi-resonant controller is used in the inner current loop controller to control the grid current and suppress the third harmonic. The designed system's steady-state and dynamic performance are tested under different PV power and sudden power changes. The simulation results show that the injected grid current is in phase with the grid voltage and has a low THD value. Also, the DC-link voltage is stable under even sudden power changes. The results prove the effectiveness of the designed system.

Published: October 2024

This study aims to activate the effectiveness of Photodynamic Inactivation (PDI) as an antibacterial agent by using a green laser and papaya leaf chlorophyll extract to prevent Candida albicans cell death. Papaya leaf extract chlorophyll is known to have potential as a photosensitizer (PS) through its antimicrobial properties and ability to absorb optimal light photons at a wavelength range of 405–680 nm. Activation of chlorophyll molecules with appropriate light produces Reactive Oxygen Species (ROS), which are toxic to pathogenic microbes such as Candida albicans. The research method involves using PDI with a green laser light source and chlorophyll extract on Candida albicans biofilms. Four main treatment groups were applied, negative control (C-), positive controls with 10% (C1+) and 15% chlorophyll (C2+), irradiation for 60, 120, 180, 240, and 300 seconds (L1–L5), and combinations of irradiation with chlorophyll (L1F1–L5F2, where F1 for 10% chlorophyll and F2 for 15% chlorophyll), with measurements performed three times for each treatment. Living Candida albicans cells were detected using the XTT assay staining method. The results showed a significant decrease in activity in all treatment groups. Maximum activity was achieved in the L5F1 and L5F2 treatment groups with inactivation of 80% (p<0.05) and 83% (p<0.05), respectively. This study concludes that high papaya leaf extract chlorophyll concentrations combined with a green laser effectively inhibit Candida albicans biofilm.

Authors: Samuel Wawirahi Wahono  , I Gde Ardika Nuaba  , I Ketut Suanda
Published: October 2024

Introduction: Thyroglossal duct cysts are common congenital neck anomalies in children, diagnosed through clinical assessment and ultrasound, and treated with the Sistrunk procedure to prevent complications like infection and malignancy. Case Description: We present a case of a 4-year-old male patient with a progressively enlarging neck mass for three months. The mass was asymptomatic, did not cause any eating difficulties, and moved upwards during swallowing and tongue protrusion. Upon physical examination, a soft, mobile, cystic mass approximately 3 cm in diameter was identified beneath the hyoid bone. Supporting examinations, including ultrasound and fine-needle aspiration cytology, led to the diagnosis of a thyroglossal duct cyst. The patient underwent a successful Sistrunk procedure, which involved the excision of the cyst along with a portion of the hyoid bone. Postoperative management included administration of intravenous antibiotics and paracetamol, culminating in a full recovery without any signs of infection. The patient exhibited complete wound healing within two weeks. There was no evidence of cyst recurrence during a follow-up examination six months later. Conclusion: Despite being common, thyroglossal duct cysts require thorough evaluation to avoid misdiagnosis, and are typically identified by a slowly growing midline neck mass that moves with swallowing and tongue protrusion, often near the hyoid bone.

Published: October 2024

Mucoadhesive drug delivery systems (MDDS) represent an innovative method for administering drugs through oral routes such as the buccal, sublingual, and gingival areas. These systems leverage natural or synthetic polymers to ensure prolonged adherence to mucosal surfaces, enabling extended and controlled release of medication. Several factors influence the effectiveness of mucoadhesion, including the hydrophilicity of polymers, molecular weight, and environmental factors like pH and moisture levels. MDDS can take various forms, including tablets, films, patches, lozenges, and gels, each offering different drug release profiles such as immediate, sustained, or controlled. These systems enhance drug bioavailability by avoiding first-pass metabolism, making them particularly beneficial for medications with low oral bioavailability or those requiring targeted delivery. Although MDDS offer improved patient compliance and therapeutic effectiveness, they still face challenges like irritation, taste concerns, and the diluting effect of saliva, which can impact drug stability. Despite these challenges, MDDS hold significant promise for advancing drug delivery technologies across various medical applications. This review thoroughly examines the mechanisms, advantages, limitations, and future prospects of mucoadhesive drug delivery systems.

Published: October 2024

This study aims to evaluate the effectiveness of integrated strategies—communication protocols, mediation techniques, and quality assurance (QA) measures—in reducing medical errors among older veterans within the Veterans Health Administration (VHA). The research seeks to identify key factors contributing to errors and assess the impact of targeted interventions on enhancing patient safety. A mixed-methods research design was employed, combining qualitative interviews with healthcare providers, veterans, and caregivers, alongside quantitative analysis of medical records, incident reports, and patient safety surveys. The study utilized stratified sampling to ensure diversity across different VHA facilities and applied statistical techniques, including chi-square tests, logistic regression, and bootstrapping, to evaluate the effectiveness of interventions. The findings indicate a significant reduction in medical errors through the implementation of standardized communication protocols, particularly during patient handoffs. Mediation effectively resolved conflicts arising from errors, fostering a culture of transparency and continuous improvement. Facilities with robust QA programs demonstrated higher success rates in identifying and mitigating potential risks. The integration of these strategies led to a 45% reduction in overall error rates, with communication errors showing the most substantial decline. The study highlights the critical role of communication, mediation, and QA in enhancing patient safety within veterans' healthcare. While the results demonstrate the effectiveness of these strategies, challenges such as resource variability and the need for ongoing training persist. The research underscores the importance of adopting a multi-faceted approach to error reduction and suggests further exploration of advanced technologies and longitudinal studies to assess the sustainability of these interventions.
On review on herbal drug and drug interactions
Authors: Shaikh Daniya Mohammed Shakil  , Chaudhari Nikita S
Published: October 2024

Herbal drugs are defined as any form of a plant or plant product that contains a single herb or combinations of herbs that are believed to have complementary effects. Although they are considered to be safe, because they are natural, they may have various adverse effects, and may interact with other herbal products or conventional drugs. These interactions are especially important for drugs with narrow therapeutic indices. Concurrent use of herbs may mimic, magnify, or oppose the effect of drugs. Plausible cases of herb-drug interactions include: bleeding when warfarin is combined with ginkgo (Ginkgo biloba), garlic (Allium sativum), dong quai (Angelica sinensis), or danshen (Salvia miltiorrhiza); mild serotonin syndrome in patients who mix St John’s wort (Hypericum perforatum) with serotonin-reuptake inhibitors; decreased bioavailability of digoxin, theophylline, cyclosporin, and phenprocoumon when these drugs are combined with St John’s wort; induction of maniain depressed patients who mix antidepressants and Panax ginseng; exacerbation of extrapyramidal effects with neuroleptic drugs and betel nut (Areca catechu); increased risk of hypertension when tricyclic antidepressants are combined with yohimbine (Pausinystalia yohimbe); potentiation of oral and topical corticosteroids by liquorice (Glycyrrhiza glabra); decreased blood concentrations of prednisolone when taken with the Chinese herbal product xaio chai hu tang (sho-saiko-to); and decreased concentrations of phenytoin when combined with the Ayurvedic syrup shankhapushpi. Anthranoid-containing plants (including senna [Cassia senna] and cascara [Rhamnus purshiana]) and soluble fibres (including guar gum and psyllium) can decrease the absorption of drugs.

Published: October 2024

Tolerance in religion practices among different groups or differen religious communities is always important in plural societies like Indonesia. However, the fact shows that many intolarance cases still occur in the country. This study is an endevour to explore the tolerance teaching brought  by Gus Baha in his traditional islamic lectures. In addition, the reaction of the public to the teaching was also examined. It adopted a digital ethnography approach employing virtual data as the main sources, including YouTube Video, and the comments of netizen following them. The ideas of tolerance were analyzed thematically, and the comments were classified, following the Appraisal theory (Martin & Rose, 2005). Based on the analysis, it reveals that Gus Baha makes use of old stories involving prophets, the Prophet and his companion as they implemented tolerant practices of daily business and religious matters. The stories there proved upscaled tolerance exemplified by the best models for Moslem communities. The public (netizen) have shown positive responses toward the ideas, as it is proved from their positive emotion (80%), and judgment (74%), meaning they like the idea and agree that they are right. In turn, it is expected that they would practice the models of tolerance in their own daily lives.

Published: October 2024

Permasalahan mengenai dominasi kaum wanita dalam budaya kerja pengerih di Desa Pandu Raya ini menjadi topik permasalahan yang cukup menarik untuk diteliti. Hal ini dikarenakan beban pekerjaan yang seharusnya menjadi tanggung jawab kaum pria, berubah menjadi tanggung jawab kaum wanita. Budaya kerja pengerih sendiri merupakan budaya kerja sama atau gotong–royong didalam masyarakat Desa Pandu Raya dan sekaligus menjadi suatu tradisi atau budaya leluhur masyarakat Suku Dayak Panu. Walaupun telah mengenal sistem pembagian kerja yang jelas antara kaum pria dan wanita, namun dapat dilihat bahwa kaum wanita adalah kaum yang dominan dari pada kaum pria. Kurang terlibatnya kaum pria dalam budaya kerja pengerih disebabkan oleh profesi yang telah dimiliki oleh kaum pria seperti Petani Sawit, Petani Karet, karyawan perusahaan, Guru, Pedagang Kecil, dan lainnya sehingga untuk terlibat dalam budaya kerja pengerih bagi kaum pria hanya dapat dilakukan apabila waktu luang saja.

Objective — to determinate the state of prooxidant‑antioxidant balance in patients with type 2 diabetes mellitus with nephropathy — carriers of different genotypes of G894T (rs 1799983) polymorphism of eNOS gene.
Materials and methods. 126 patients with diabetic nephropathy (DN) were examined. The control group included 20 healthy individuals. Patients with type 2 diabetes mellitus (DM) were divided into two groups depending on the eNOS rs 1799983 gene polymorphism: group I — patients with DN and G/G genotype eNOS G894T gene (n=80); group II — patients with DN and G/T and T/T genotypes eNOS G894T gene (n=46).
Results. The distribution of genotypes of the rs1799983 polymorphism of the eNOS gene corresponded to the Hardy‑Weinberg equilibrium. Data analysis demonstrated a significant difference in the frequency of occurrence of genotypes and alleles of the studied polymorphism in the group of patients with DN compared with controls, which corresponds to the dominant model of inheritance (odds ratio 0.31 (95% confidence interval 0.09—0.99), p=0.045). There were significant gender differences in the frequency of genotypes and alleles of the studied polymorphism in the group of patients with type 2 DM with DN: women had a significantly lower risk of the G/T polymorphism genotype than men. The study of total antioxidant activity (TAA) revealed significantly lower values of this parameter in patients with G/G genotype of the rs1799983 polymorphism of the eNOS gene compared to carriers of the T allele (G/T+T/T genotypes). In diabetic patients with different genotypes of the rs1799983 polymorphism of the eNOS gene, the levels of total hydroperoxides (THP) did not differ significantly. Homozygous and heterozygous carriers of the T allele of the rs1799983 polymorphism of the eNOS gene had a significant increase in the prooxidant‑antioxidant balance.
Conclusions. In patients with DN, the distribution of genotypes of the G894T polymorphism (rs 1799983) of the eNOS gene corresponds to the Hardy‑Weinberg equilibrium in all studied groups and does not differ significantly from European populations. In men, the risk of having a heterozygous G/T genotype of the G894T (rs 1799983) polymorphism of the eNOS gene is 3 times higher than in women (according to the dominant model of inheritance, odds ratio 0.41 (95% confidence interval 0.20—0.83), p=0.013). In carriers of G/T and T/T genotypes, a significant increase in prooxidant‑antioxidant balance was observed against the background of a decrease in total antioxidant activity, compared with carriers of G/G genotype (p<0.05).

Minocycline, a second-generation tetracycline derivative, is proven to inhibit glial scar formation in several neurological diseases. However, studies associating micocycline in traumatic brain injury (TBI) is very limited. This review aims to determine the role of minocycline in inhibiting glial scar or astrogliosis formation in TBI animal models. This scoping review includes original studies in PubMed, Science Direct, and Google Scholar databases published between 1 January 2012 to 31 December 2022, in full text, involving rodent research, and written in English. Two authors who followed the Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR) guidelines, conducted the assessment independently. Of 2687 studies, 13 studies are reviewed. Two studies describe the benefits of minocycline in inhibiting glial scar formation in TBI, while 11 studies show that minocycline inhibits glial scar formation in diseases other than TBI. An explanation of the signaling pathways and cells involved in the mechanism of glial scar inhibition by minocycline can be found in ten articles, of which four observe the role of microglial cells, four observe the role of astrocyte cells, and two do not explain the mechanism. Research on the impact of minocycline in inhibiting glial scar formation in rats with TBI is limited. The results of this review support early research on the role of minocycline in inhibiting glial scar or astrogliosis in TBI, and similar studies in several other CNS diseases support this. However, the mechanism of minocycline's inhibitory pathway to glial scarring remains unclear.

The authors presented their own clinical observation of an aneurysm of the left portal vein branch in a teenager with a long-term asymptomatic course. Reduced serum concentrations of ceruloplasmin and α-1-antitrpsin made diagnostic search difficult, which could lead to incorrect therapeutic decisions. However, the results of imaging methods allowed us to establish the root cause of liver damage and its cirrhotic transformation. Vascular aneurysms of the portal vein system are a very rare pathology, and it should be taken into account in the differential diagnostic algorithm while excluding other, more obvious causes of liver pathology.

The current problem of neonatal and pediatric surgery remains the tactics of surgical treatment and postoperative management of patients with perforated peritonitis. Mortality with perforation of the stomach and intestines in children in the newborn period reaches about 40-80 %. The combination of the syndrome of increased intra-abdominal pressure and multiple organ failure causes the extremely serious condition of patients. In this connection, new approaches to the surgical treatment of such patients are currently being actively developed. For this, new medical devices are tested in experimental practice, but the problem of such studies, first of all, lies in the lack of an adequate model of the pathological process. The aim of the work is to analyze the methods of experimental modeling of intestinal perforations described in the public domain. For this, a study was conducted of the most significant scientific publications of such databases as Google Scholar, PubMed, Scopus, eLIBRARY. The present work provides a detailed description of existing options for modeling perforations of various parts of the gastrointestinal tract (stomach, small intestine and colon), depending on the goals of the experiment. Several rather rare techniques based on the introduction of microorganisms are also presented. In addition, the article describes the method proposed by the authors for modeling perforation using laparoscopic access.

In children, autoimmune liver diseases can manifest in a variety of forms, including autoimmune hepatitis (AIH), primary sclerosing cholangitis (PSC), and the co-occurrence of AIH and PSC - the “overlap syndrome.” Early recognition of overlap syndrome is important. Diagnosis of sclerosing cholangitis largely depends on the cholangiographic picture showing single or multiple strictures with dilatation of the biliary tract. The problems of etiology, pathogenesis, diagnosis and treatment of overlap syndrome in children are shown. A clinical example of seronegative autoimmune hepatitis and sclerosing cholangitis as part of a cross syndrome in a child is given.
