    İnsan - endüstriyel mobil robot etkileşiminde güvenlik önlemlerinin boyutlandırılması için nesne tespit modeli geliştirme
    (Gazi Universitesi, 2024) Aslan, Tarık; Yağımlı, Mustafa
    İnsan-robot etkileşiminde, güvenlik önlemleri için geleneksel olarak tek düzey güvenlik önlemleri uygulanır ve çalışanlara ait kriterler dikkate alınmaz. Bununla birlikte nesne tespit teknolojisi kullanılarak yeni bir yöntem geliştirilebilir; koruyucu donanım kullanımı ve yetki seviyeleri gibi çalışanlara özgü kriterleri tespit edilerek insan-robot etkileşimi risk seviyesi belirlenebilir ve risk büyüklüğüne bağlı olarak farklı büyüklükte güvenlik önlemleri uygulanabilir. Bu araştırmada, YOLOv5n, YOLOv8n ve SSD MobileNet V3 nesne tespit modelleri bu amaçla geliştirilmiş ve analiz edilmiştir. Bulgular, YOLO ailesine ait mimarilerin daha hızlı çalıştığını ve daha yüksek doğruluk seviyelerine ulaştığını ortaya koymuştur. YOLOv5n algoritması GPU kullanımı ile 650 FPS hıza ve test verileriyle yapılan değerlendirme sonucunda %95,7'lik bir F1 doğruluk değerine ulaşılmıştır. Sonuçlar, nesne tespit teknolojisinin yakınlık senyörleriyle eş zamanlı olarak uygulanabilecek bir doğruluk ve hıza ulaştığını ve endüstriyel mobil robotların güvenlik önlemleri almadan önce çalışanların özelliklerini tespit edebileceğini ve riskleri derecelendirebileceğini göstermektedir. Bu durum daha güvenli çalışma ortamı oluşmasına, gereksiz önlemlerin elimine ve operasyonel verimliliğin optimize edilmesine olanak verir. Ayrıca bu yöntem, güvenli çalışma ortamların sağlanmasına yönelik olarak birçok sektörde ve alanda da uygulanabilir.

    Co2 emisyonlarını etkileyen faktörlerin zamanla değişen katsayılı parametrik olmayan panel veri modelleri ile analizi
    (İstanbul Üniversitesi, 2023) Güriş, Selahattin; Çağlayan, Sevcan
    İklim değişikliğinin, küresel ısınmanın ve çevresel bozulmanın bir nedeni olarak karbondioksit (CO2) emisyonlarından oluşan sera gazları gösterilmektedir. CO2 yeryüzüne insan faaliyetleri nedeniyle yayılarak genellikle çevreye zarar verir ve iklim değişikliğine veya küresel ısınmaya yol açar. Bu sebeple CO2 emisyonlarını etkileyen ekonomik ve ekonomik olmayan birçok sosyal faktör araştırmalara konu olmuştur. Ancak çoğu araştırmada CO2 emisyonları konusunda hem ekonomik büyüme hem de enerji kullanımı gibi ana faktörleri de etkileyen ekonomik belirsizlik dikkate alınmamıştır. Bu çalışmada kişi başına düşen CO2 emisyonları ve başta ekonomik belirsizlik (dünya belirsizlik indeksi ile ölçülen) olmak üzere diğer değişkenler arasındaki ilişki ele alınmıştır. 14 OECD ülkesinin 2000-2021 yılları arasındaki verileri zamanla değişen katsayılı parametrik olmayan panel veri modeliyle incelenmiştir. Trend fonksiyonları ve parametrik olmayan katsayı fonksiyonları tahmin edilerek doğrusal olmayan sonuçlara ulaşılmıştır. Parametrik olmayan katsayı fonksiyonlarının CO2 emisyonları üzerinde etkisi zaman içerisinde değişiklik göstermektedir. Sonuçlarımıza göre ele alınan dönem boyunca ekonomik belirsizlik ile CO2 emisyonları arasında ters yönlü bir ilişki bulunmaktadır ve zaman içerisinde düşüş eğiliminde devam etmektedir. Kişi başına düşen GSYH, nüfus ve yenilenebilir enerjinin parametrik olmayan katsayıları zaman içerisinde negatif ve pozitif olarak değişmektedir. Ticaret 2000’li yıllarında başında anlamsız bir değişken olmasına rağmen 2009-2013 yılları arasında anlamlı bir değişkendir, ancak 2021 yılında etkisi tekrar anlamsızlaşmıştır.

    Navigating humanitarian aid in syria: challenges, complexities, and paths to sustainable solutions
    (SETA Foundation, 2024) Baroud, Saeed; Karsavuran, Orhun Cem; Atar, Emrah
    This study explores the role of foreign aid as a soft power tool by providing an understanding of the interrelation between foreign policy and aid. The study is based on interviews with aid experts. The findings of the study unambiguously demonstrate that aid and foreign policy are intertwined since, in most cases, foreign aid falls under the responsibility of foreign ministries. Besides the humanitarian imperative, the geopolitical account has a crucial importance in the decision-making process that cascades down from the general foreign policy agenda. In addition, the strategic interests of the donor country are contributing to the decision-making. The prominent themes are national security, tackling terrorism, preventing immigration influx, and economic goals. The study also demonstrates the extent to which aid can be politicized in its extreme form by focusing on Russian vetoes in the UN Security Council and the Syrian government’s weaponization of aid.

    (Turkish League Against Rheumatism, 2023) Kartaloğlu, Işıl Fazilet; Karagül, Sevil; Arslan, Şule
    Objectives: This study aimed to determine whether maternal diagnosis of Fibromyalgia syndrome (FMS) affects the sleep quality of children. Patients and methods: This prospective study was conducted with 80 female participants (mean age: 36.2 +/- 5.9 years; range 25 to 50 years) and their 80 children (27 males, 53 females; mean age: 6.6 +/- 2.6 years; range 2 to 12 years) between August 2019 and November 2020. The FMS group included 40 female FMS patients and their children, whereas the control group consisted of 40 healthy females and their children. In addition to sociodemographic variables, functional status was evaluated by the Fibromyalgia Impact Questionnaire (FIQ), which was completed by mothers with FMS, and the Children's Sleep Habits Questionnaire (CSHQ) was used to evaluate the sleep quality of all children. Results: There was no statistically significant difference between the two groups in terms of demographic characteristics ( p > 0.05). The CSHQ score of the two groups was above 41 points and was at a clinically significant level. The median value for the CSHQ score was 60.5 and 52 in the FMS and control groups, respectively. Sleep time, waking up at night, parasomnias, disrupted breathing during sleep, and sleepiness scores were higher in the FMS group than in the control group, and the differences were statistically significant (p < 0.001). The delayed falling asleep score, which was reversely coded, was lower in the FMS group than in the control group, and the difference was statistically significant (p < 0.001). Conclusion: This pilot study showed that the children of mothers with high Fibromyalgia Impact Questionnaire scores had sleep disorders. Maternal diagnosis of FMS negatively affects the sleep quality of children.

    (Pamukkale University, 2020) Çiçek, Bünyamin; Aydoğmuş, Tuna; Gündoğdu İş, Emine; Sun, Yavuz
    In this study, it has been reported that Q345B steel combine with different steels using electric arc welding method and the mechanical properties were investigated. Produced by hot rolling processes, Q345B steel is a low-alloyed medium tensile strength and highly usable steel. The steel used contain less than 0.2% carbon and less than 0.55% silicon, chromium and nickel. In this study, Q345B steel generally used at low-pressure/temperature zones in thermal power plant (boiler wall etc.) is combined with 16Mo3 and P265GH steels. The Q345B steel is welded to make the mechanical properties easy to compare. After joining, specimens were collected from the welded areas and used in the preparation of mechanical and metallographic processes. In this process, all joints were subject to tensile, charpy, hardness and bending tests. In addition, the collection of macro images from welding were used in observation of transition zones which were operated. Electrodes with a basic character cover were used (E7018) as filler metal in the joining processes. All mechanical tests met the requirements of the relevant standards and all welds were identified as valid weld.

    Effect of administering kefir on the changes in fecal microbiota and symptoms of inflammatory bowel disease: a randomized controlled trial
    (AVES, 2019) Yılmaz, İlkay; Dolar, M. Enver; Özpınar, Haydar
    Background/Aims: Kefir is a kind of fermented probiotic dairy product. The objective of the present study was to investigate the effects of kefir consumption on the fecal microflora and symptoms of patients with inflammatory bowel disease (IBD). Materials and Methods: Kefir was serially diluted and inoculated into de Man, Rogosa, and Sharpe agar and incubated at 37 degrees C for 48 to 72 h under anaerobic conditions. This was a single-center, prospective, open-label randomized controlled trial. Forty-five patients with IBD were classified into two groups: 25 for treatment and 20 for control. A 400 mL/day kefir was administered to the patients for 4 weeks day and night. Their stool Lactobacillus, Lactobacillus kefiri, content was quantitated by real-time quantitative polymerase chain reaction before and after consumption. Abdominal pain, bloating, stool frequency, stool consistency, and feeling good scores were recorded in diaries daily by the patients. Results: A 5x10(7) CFU/mL count of lactic acid bacteria colony forming units was found in a kefir sample as the total average count. Lactobacillus bacterial load of feces of all subjects in the treatment group was between 10(4) and 10(9) CFU/g, and the first and last measurements were statistically significant (p=0.001 in ulcerative colitis and p=0.005 in Crohn's disease (CD)). The L. kefiri bacterial load in the stool of 17 subjects was measured as between 10(4) and 10(6) CFU/g. For patients with CD, there was a significant decrease in erythrocyte sedimentation rate and C-reactive protein, whereas hemoglobin increased, and for the last 2 weeks, bloating scores were significantly reduced (p=0.012), and feeling good scores increased (p=0.032). Conclusion: According to our data, kefir consumption may modulate gut microbiota, and regular consumption of kefir may improve the patient's quality of life in the short term.

    Effects of game addiction on musculoskeletal system discomfort and mental toughness in e-sport players
    (Turkish Green Crescent Society, 2022) Kendal, Kübra; Ataç, Amine; Köse, İlkay Tuğçe
    The aim of this study is to reveal the level of game addiction, musculoskeletal system complaints, and mental toughness and to investigate musculoskeletal system discomfort risk and mental toughness by the addiction level in e-sports players. The population of the study consisted of a total of 204 e-sports players on various platforms in Turkey, 94 of whom were game addicted and 110 were not according to the seven-item Game Addiction Scale. The players were given the Demographic Data Form, the Cornell Musculoskeletal Discomfort Questionnaire (CMDQ), the Cornell Hand Discomfort Questionnaire (CHDQ), and the Sports Mental Toughness Questionnaire (SMTQ). In CMDQ and CHDQ parameters, neck (7.55 +/- 18.16 vs. 2.06 +/- 4.26; p =.014), upper back (9.32 +/- 19.41 vs. 3.32 +/- 7.56; p =.024), lower back (12.27 +/- 24.93 vs. 2.75 +/- 5.47; p =.007), hip (2.89 +/- 9.90 vs..88 +/- 2.89; p =.013), right hand B (2.18 +/- 10.34 vs..24 +/- 1.24; p =.005) and F regions (1.76 +/- 3.81 vs..82 +/- 2.96; p =.041) were significantly better in the non-addicted group. In SMTQ, the control sub-dimension (10.68 +/- 3.27 vs. 12.75 +/- 2.67; p <.001) and total scores (36.32 +/- 6.74 vs. 38.46 +/- 7.11; p =.021) were significantly better in the non-addicted group. These findings reveal that as the game addiction score increases, the risk of musculoskeletal system discomfort increases and mental toughness decreases. These results should be taken into account in e-sports players where a sedentary lifestyle is at the forefront.

    Alcohol use disorder and emotional abuse: the mediating role of early maladaptive schemas
    (Cumhuriyet University, 2019) Can, Yeşim; Anlı, İrem; Evren, Cüneyt; Yılmaz, Doğan
    Objective: Studies have shown a relationship between the development of alcohol use disorder (AUD) and the existence of childhood traumas (CT). In this study, in order to gain a better understanding of the association between CT and AUD, the relationship between CT and AUD was analyzed. Further, it was investigated whether Early Maladaptive Schemas (EMS) play a mediating role in the relationship between emotional abuse (EA) and AUD. Methods: The participants were consecutively admitted male alcohol-dependent inpatients (n=220) and healthy controls (n=108). The participants were investigated with the Childhood Trauma Questionnaire (CTQ-28), Young Schema Questionnaire-Short Form (YSQ-SF) and Michigan Alcoholism Screening Test (MAST). Mediation analyses were conducted in order to evaluate the mediating effect of EMS between the relationship of AUD and CT. Results: The difference between CT total score and the EA score between the control group and the AUD group were statistically significant. An analysis of different types of traumas in the correlation with AUD revealed EA as the main predictor of AUD both directly and through its mediating effect with the EMS. In addition, it was determined that in the relationship between EA and AUD, EMS such as Enmeshment, Emotional Inhibition, Dependence and Insufficient Self-Control had mediating effect. Discussion: CT, especially EA are quite common in male inpatients with AUD and the negative effects of EA may play an important role in the development of AUD by causing EMS. Our findings imply that those with EA history in childhood may be particularly vulnerable to the development of AUD in adulthood. Therefore, in the prevention of the development and in the treatment of AUD, it may be useful to take into consideration EA experiences, to screen EMS that may mediate such relationship through scales and to conduct interventions in this regard.

    Pregnancy-related lumbopelvic pain and disability: an invisible and neglected problem
    (Atatürk University, 2023) Erten, Hacer; Aygün, Mahmure; Yılmaz Esencan, Tuğba; Doğan Merih, Yeliz
    Objective: This study was carried out to examine the frequency of lumbopelvic pain in pregnant women, the level of disability associated with it, and the factors that may affect the level of disability. Methods: The descriptive, cross-sectional and analytical study was carried out with 381 pregnant women who received service from the routine pregnancy follow-up outpatient clinic of a state hospital. A form including demographic, obstetric, and other descriptive characteristics of the cases, a visual pain zone diagram to determine the pain area, and the Roland-Morris Disability Questionnaire (RMDQ) to determine the disability level were used as data collection tools. Descriptive statistical methods and non-parametric tests were used in the analysis of the data. Results: It was determined that 86.35% (n = 329) of the participants had lumbopelvic pain and were mildly disabled according to the RMDQ total score (12.0 +/- 7.3). In the analysis performed according to subgroups, the mean RMDQ scores of pregnant women with pelvic girdle pain were found to be statistically significantly higher than those with low back pain (P <.05). Other variables associated with high disability scores were education level, parity, occupation, gestational week (trimester), presence of lumbopelvic pain in the previous pregnancy, work stress, and negative sexual life history (P <.05). Conclusion: Lumbopelvic pain is a condition that is common in pregnancy, can cause different levels of disability depending on some factors, and should not be ignored by antenatal care providers.

    Nursing care in robotic radical cystectomy and intracorporeal orthotopic urinary diversion surgeries
    (Galenos Publishing House, 2023) Bakanoğlu Kalkavan, Emek; Şendir, Merdiye
    In this article, the management of nursing care in robotic cystectomy and urinary diversion surgeries, which are performed for treating bladder cancer, is explained considering the current literature. Bladder cancer is a type of cancer that is highly prevalent worldwide, and it is seen more frequently in men than in women. Radical cystectomy with pelvic lymphadenectomy are the reference treatment for muscle-invasive bladder cancer, and they play a key role in managing high-risk nonmuscle-invasive cancer and saving the patient following radiotherapy. While radical cystectomy involves the removal of the bladder, urethra, uterus, Fallopian tubes, ovaries, and anterior vagina in women, it involves the removal of the bladder, urethra, prostate, and seminal glands in men. Urinary diversion performed following robotic cystectomy is a curative surgical method associated with functional and metabolic changes that could affect the patient as well as the quality of life of the patient. Urinary diversions performed following removal of the cancerous bladder aim to divert the urinary flow toward its normal path or form a new path for urine to be released directly or by accumulation. In robotic cystectomy and urinary diversion surgeries, the role of the nurse in the management of the preoperative, perioperative, and postoperative stages is highly important. The optimal management of nursing care and nurse training programs, especially for the postoperative period, aims to increase the quality of life of the patient by preventing complications, shortening their hospital stay, and organizing their activities of daily living.

    (Galenos Publishing House, 2019) Çalıkuşu İncekar, Müjde; Çeçen, Eda; Balcı, Serap; Mutlu, Birsen; Ulu Öğüt, Nehir; Hamilçıkan, Şahin
    Objective: Noise must be reduced and taken under control because negatively affects the health of health personnel and preterm newborns in particular. The American Academy of Pediatrics reported that noise levels must be kept below 45 dB. However, many studies demonstrated that the desired level could not be reached. This research was conducted with the aim of evaluating the level of noise in a neonatal intensive care unit (NICU), and the effect of given education on controlling the noise. Materials and Methods: This research was conducted with doctors (4), nurses (18), and personnel (4) who worked in the 3rd level NICU of a university hospital. This research had a pre-test, post-test quasi-experimental design in a single group. Ethics board and institutional approval were granted from the hospital. A noise information form that was prepared by researchers, educational program on noise control, noise observation form, and noise measuring equipment were used in the study. Noise was measured for 24 hours over 7 days in repeated measurements in the unit before education, after education, and 6 weeks after the education program. Results: The noise levels were significantly lower 6 weeks after the education program compared with before the program (p<0.01). The percentage of correct answers given to questions in the information form was significantly higher 6 weeks after the education program compared with before the program among health personnel (p<0.01). The kappa compliance level was found significant among observers in the evaluation of doctors, nurses, and personnel in accordance with the noise observation form (p<0.01). Conclusion: It could be suggested that the education method was effective in terms of reducing noise, reducing noise levels in the environment, improving the information level of health personnel, and positively affecting the behaviors of personnel. It can also be concluded that the noise observation form is reliable.

    (Galenos Publishing House, 2023) Karagül, Sevil; Kartaloğlu, Işıl Fazilet
    Objective: Osteoporosis can be followed secondary to hypothyroidism and hyperthyroidism. In this study, we evaluated the awareness and knowledge of osteoporosis in patients with hypothyroidism and hyperthyroidism.Materials and Methods: A total of 148 patients and 148 volunteers, 80 of whom were diagnosed with hypothyroidism and 68 with hyperthyroidism, were included in the study. Demographic information and socioeconomic status of all patients and volunteers were recorded. Participants were evaluated using the osteoporosis knowledge test and osteoporosis awareness scale. For the osteoporosis knowledge questionnaire, correct answers of 13 and above were considered sufficient and answers below 13 were considered insufficient. First, the patient and volunteer groups were compared, and then the patient group was divided into two groups as hypothyroidism and hyperthyroidism. Questionnaires measuring osteoporosis awareness and osteoporosis knowledge levels of hypothyroid and hyperthyroid patients were compared.Results: There was no difference between the patient and control groups in terms of age, gender, education level, and income level (p>0.05). Both the patient and control groups had osteoporosis awareness, but there was no significant difference between the groups (p>0.05). The awareness of osteoporosis was high in the hypothyroid-hyperthyroid patient and control groups. When the osteoporosis knowledge levels of the patient and control groups were compared, a statistically significant difference was found in favor of the control group (p<0.05). No statistically significant difference was found regarding the osteoporosis awareness levels of hyperthyroid and hypothyroid patients (p>0.05). The osteoporosis knowledge level was low in patients with hypothyroidism and hyperthyroidism.Conclusion: Osteoporosis awareness was high in the hypothyroid and hyperthyroid patient and control groups. Considering the osteoporosis knowledge levels of the patient and control groups, although the knowledge level was insufficient in both groups, the decrease in the patient group was significant.

    (Galenos Publishing House, 2019) Çalıkuşu İncekar, Müjde; Yangil, Ayşe İpek; Kaya, Gizem; Genç, Gamze; Doğan, Zehra; Yıldız, Suzan
    Aim: This study was conducted to determine the relationship between psychosocial development and liking of children in nurses working in pediatric clinics. Materials and Methods: This study was conducted as a descriptive and correlational study on 110 nurses working at two hospitals. Data were collected using an information form, the Modified Erikson Psychosocial Stage Inventory, and the Barnett Liking of Children scale. Descriptive statistical tests, Mann-Whitney U test, Kruskal-Wallis test, Pearson correlation and regression analysis and Cronbach's alpha were used in the data analysis stage. Results: It was found that there was a positive, weak, and significant correlation between the liking of children and the subscales of trust, autonomy, industry, identity, and generativity (p<0.05). At the same time, there was a very weak, positive, and significant correlation between the liking of children and the subscales of initiative and ego integrity (p<0.05). No significant correlation was observed between the liking of children and the subscale of intimacy (p>0.05). It was observed that there was a weak correlation between the level of liking of children and the determinant variables of trust, autonomy, initiative, industry, identity, intimacy, generativity, and ego integrity (R-2 =0.133). Conclusion: It was concluded that nurses' levels of trust and autonomy increased the level of liking of children.

    Walking speed gender differences in prepubertal children: an observational study
    (Galenos Publishing House, 2022) Ahmedov, Shahin; Yaman Lesinger, Figen; Oytun, Musa; Filiz, Barış; Özkan, Fatih Kerem
    BACKGROUND/AIMS: Walking speed associates with a person's functional status and balance confidence, both of which diminish with age. The difference in children's body composition and prepubertal metabolic rate suggested gender variability in their walking parameters. MATERIALS AND METHODS: The preferred step length, cadence, and overall walking speed of 457 school children (256 boys) aged 12.65 +/- 2.16 years old were assessed during a 20 meter walk. The participants' height, weight, and heart rate values were also collected. RESULTS: The preferred walking speed analysis demonstrated that the girls, despite their shorter height and age, moved faster than the boys (1.35 +/- 0.22 m/sec in boys. 1.43 +/- 0.22 m/sec in girls, p<0.01). The girls' baseline heart rate correlated with their final walking speed (n=177, r=0.202, p<0.05). Although, as expected, the children's step length positively correlated with their height (n=457, r=0.42; p<0.05), with an increase in the child's height, the step-to-height ratio decreased significantly (n=457, r= -0.40; p<0.05). The average walking speed in prepubertal children (1.39 +/- 0.22 m/sec) was the highest among all population groups. CONCLUSION: Girls demonstrated better walking performance compared to boys. The preferred walking speed allows for a quick assessment of the child's physical development necessary for effective exercise programs.

    Amaç: Bu çalışma, hemşirelerin COVID-19 korkusunun beslenme alışkanlıklarına ve takviye gıda kullanımına etki sini belirlemek amacıyla yapıldı. Yöntemler: Tanımlayıcı ve kesitsel nitelikteki araştırma; basit rastgele örnekleme yöntemi ile pandemide aktif olarak çalışan ve çalışmaya katılmayı kabul eden 485 hemşire ile Aralık 2020 - Mart 2021 tarihleri arasında gerçekleştirildi. Veriler, ilgili literatür doğrultusunda hazırlanmış olan soru formu ve “COVID-19 Korkusu Ölçeği” ile elde edildi. Ve rilerin değerlendirilmesinde; sayı, yüzde, ortalama, standart sapma, medyan, minimum, maksimum, t testi, varyans analizi (ANOVA) ve x2 testi kullanıldı. Bulgular: Hemşirelerden, pandemi sürecinde gıda takviyesi kullanan, yeterli ve dengeli beslenmeyen, çalışma koşulları nedeniyle çoğu zaman yemek yiyemeyen, gıda takviyesini COVID-19’un önlenmesinde ve/veya tedavisine yardımcı olması amacıyla kullanan, gıda takviyesini düzenli kullanan ve çevresindeki bireylere tavsiye edenlerin korku düzeyleri daha yüksek olarak bulundu (p<0.05). Sonuç: Hemşirelerin pandemi öncesinde ve pandemi sürecinde gıda takviyesi kullanım durumlarında artış olduğu ve bu artışın istatistiksel olarak anlamlı düzeyde olduğu belirlendi (p<0.001).

    A comparative study of silver electrodeposition from pyrophosphate-cyanide and high concentration cyanide electrolytes in the presence of brighteners
    (Tubitak Scientific & Technological Research Council Turkey, 2020) Akben, Hatice Kübra; Timur, Servet İbrahim
    A study of the electrodeposition of silver from 2 different types of electrolytes; (1) neutral pyrophosphatecyanide electrolyte and (2) alkaline high concentrated cyanide electrolyte in the presence of a variety of additives such as 2-mercaptobenzothiazole, potassium selenocyanate, and potassium antimony tartrate was performed. Influence of additives and cyanide concentration on microstructure and kinetics of the cathodic processes were studied. A brightener couple, 2-mercaptobenzothiazole and potassium antimony tartrate, were combined within this investigation and detected to be highly effective for silver electrodeposition. The rapid increase in current density at the same potential interval related to grain refinement effect of potassium antimony tartrate was shown. The cyclic organic compound, 2-mercaptobenzothiazole, polarizes the reduction to high cathodic potential in pyrophosphate electrolyte. However, the sufficient levelling effect required for the mirror-bright appearance seems to be related to the high polarizing effect of the high concentration cyanide content. In the case of pyrophosphate electrolytes, sufficient levelling cannot be achieved, so semigloss coatings are obtained. The low cathodic potential electrodeposition of silver in pyrophosphate electrolyte, which is found to proceed by 3D instantaneous nucleation, is polarized to high cathodic potentials and grows into 3D progressive nucleation and diffusion-controlled growth in high concentration cyanide electrolyte.
