Electrocoagulation for D-pinitol enrichment from carob extract: Plate selection. Consulting and Training Centre KEY.
No full textD-Pinitol (3-O-methyl-D-chiro-inositol), a bioactive compound holds promise
for its anti-diabetic properties. However, synthesizing D-pinitol in laboratory
settings is prohibitively expensive, prompting research to focus on extracting
and purifying it from natural sources. This study introduces electrocoagulation
(EC) as an innovative technique not previously explored for D-pinitol extraction
from carob extract. EC facilitates the removal of charged compounds in colloidal
suspensions by inducing collisions and neutralization with ions of opposite
charges. The efficiency of this process largely depends on the types of plates used,
as they vary in effectiveness based on the colloidal compounds in the solution.
In this context, this study evaluated aluminum (Al) and stainless-steel (SS)
plates, commonly employed in EC research, to ascertain their effectiveness in
the extraction process. Four distinct trials were designed, positioning each plate
type at the anode and cathode ends within the EC system. The experiments
maintained fixed operational parameters (Electrode interval: 3 cm, current
density: 60 mA/cm², voltage: 30 V, and time: 60 min) in the carob extract produced
from cultivated carob fruits grown in Antalya, Türkiye. The effectiveness of EC
was assessed by determination of D-pinitol content (using HPLC separation and
refractive index detection), colorimetric analysis of total phenolic content (using
a spectrophotometer), color measurement (using a colorimeter), and turbidity
measurement (using a turbidimeter) in the post-treatment
The study found that the Al (-) and SS (+) plate combination significantly
enhanced D-Pinitol yield by 23%, increasing it from 17 to 42.36 g/100 g dry matter.
Additionally, there were reductions in total phenolic content and turbidity, along
with an improvement in color (L value). The results indicate the success of EC as an intermediate process for D-Pinitol
purification.No sponso

No full textÇalışmanın amacı, Türkiye'de COVID-19 salgını sırasında yaşam doyumunun, umutsuzluğun, psikolojik
dayanıklılığın ve algılanan stres düzeylerinin üniversite öğrencilerini nasıl etkilediğini araştırmaktır.
Kesitsel nitelikteki bu çalışmanın toplam örneklemi 615 üniversite öğrencisinden oluşmaktadır; Çevrimiçi anket
formuyla 410 kadın ve 205 erkek toplandı. Katılımcıların yaş ortalaması 21 olarak hesaplanmıştır. Veriler “Beck
Umutsuzluk Ölçeği”, “Yaşam Memnuniyeti Ölçeği”, “Algılanan Stres Ölçeği” ve Yetişkinler İçin Psikolojik
Dayanıklılık Ölçeği” kullanılarak toplanmıştır. Verilerin analizi için ANOVA , Kruskal Wallis H Testi ve Bağımsız
Örneklem T testi kullanıldı.
Bulgular, kronik tıbbi rahatsızlığı olanların algılanan stres düzeyinin ve umutsuzluk düzeyinin daha yüksek olduğunu
ortaya koydu. Sonuçlar ayrıca pandemi süreci boyunca kalabalık alanlardan uzak duran ve ortak kullanım alanlarına
dokunmaktan rahatsızlık duyanların algılanan stres düzeylerinin daha yüksek olduğunu gösterdi. Sıklıkla kaygılı
hissettiklerini belirtenlerin umutsuzluk ve algıladıkları stres düzeyleri geçmişe göre daha yüksek bulunmuştur.
Eskisine göre daha fazla kaygılı hissetmediklerini belirten katılımcıların psikolojik dayanıklılık ve yaşam doyumu
düzeyleri daha yüksek bulunmuştur. Araştırmada ayrıca, COVID-19 sürecinde akademik görevlerini tamamlamada sorun yaşadığını ifade eden katılımcıların algılanan stres ve umutsuzluk düzeylerinin diğerlerine göre daha yüksek
olduğu sonucuna varıldı.
Çalışmada Türkiye'deki üniversite öğrencileri arasında COVID-19'a bağlı kaygı, algılanan stres ve umutsuzluk
düzeylerinin daha yüksek olduğu tespit edilmiştir.In our study, it is seen that there are significant relationships between Beck hopelessness scale, burnout scale, marital
life scale and quality of life scale and sub-dimension scores. Findings related to mediator analysis showed that
hopelessness had a significant partial mediator role in the effect of burnout on marital life and quality of life.
Demographic characteristics, gender, age, education, employment status, marital status, number of children, income
status, fear of COVID-19, pregnancy processes and child-related conditions were examined. Marital life scale scores
were higher in males than females. It is seen that university graduates have higher quality of life scale environmental
sub-dimension scores than primary school graduates. While the burnout and hopelessness scale scores of those with
higher income status were lower than those with lower income, marital life scale, quality of life scale environmental
and psychological health sub-dimension scores were found to be higher. While married people had higher quality of
life scale and marital life scale scores than singles, hopelessness scores were found to be lower. While it was observed
that the marital life and quality of life scores of the parents whose child's nutrition process was affected during the
COVID-19 process were lower, their hopelessness levels were higher.No sponso

However, challenges such as regulatory constraints, high implementation costs, and resistance to change limit successful integration. The study concludes that targeted investments and supportive regulations are essential for leveraging AI’s full potential and enabling sustainable modernization within Iran’s banking system.No sponso
Contribution of stevia to the perception of sweetness and bitterness in fruit drinks
No full textThe rise of healthy living trends has increased the popularity of natural sweeteners
like stevia, derived from the Stevia rebaudiana plant. This study aimed to examine
stevia’s impact on the sweetness and bitterness perceptions of apricot and sour cherry
drinks. Initially, fruit drinks with 0% stevia (control group sugar source: saccharose)
were produced using an optimal formulation (100 g sugar, 20% fruit puree, 0.3% citric
acid, 1 L distilled water) based on Karhan et al.’s experiment (2024). In the earlier
panel reviews, a 75% stevia substitution ratio was found to be the best. This study also
tested that ratio, and all stevia-substituted fruit drinks (75 and 100%) were made using
Karhan et al.'s formula. In the post-production stage, the drinks underwent pH and total
soluble solids (Cemeroğlu, 2007), and sensory analyses with panelists (N = 12) using
intensity scale (1: Very low, 9: Very high) and ranking (1: Most liked, 6: Least liked)
tests (Lawless & Heymann, 2010).
Results showed that increasing stevia concentrations decreased the pH values of
apricot drinks more than sour cherry drinks. High stevia levels significantly lowered
soluble solids in both drinks. Sensory analysis indicated that higher stevia
concentrations reduced sweetness perception, especially in apricot drinks, and
increased bitterness as sucrose-derived sugar content decreased. This shift in the
balance between sweetness and bitterness resulted in a less sweet and more bitter flavor
profile.
The apricot drink with 0% stevia was the most favored, but the 75% stevia apricot
drink also performed well, suggesting effective harmonization with apricot at
appropriate ratios. However, drinks totally sweetened with stevia, particularly apricot,
were least favored, indicating high stevia doses might adversely affect the authentic
taste of apricot. Sour cherry drinks with 100% stevia received slightly better scores than
their apricot counterparts. Overall, acceptance of stevia as a sweetener varied by fruit
type and concentration. Apricot drinks were preferred more with 75% stevia, while sour
cherry drinks were less preferred at the same concentration. The data suggest that stevia
can create a favorable taste profile when used in suitable compositions and ratios.
In summary, panelists rated sweeter drinks as less bitter, indicating sweetness masks
bitterness. The effect of stevia on bitterness was less pronounced in sour cherry drinks,
suggesting a better blend with sour cherries. The findings of this study highlight that
20
Uluslararası Tüketici ve Duyusal Bilimler Konferansı Bildiriler Kitabı
stevia has good potential when applied in the right proportions. The desired amount of
this natural sweetener should be specifically designed for each product. The study also
emphasizes the significance of optimizing stevia concentrations to effectively balance
sweetness and bitterness. To ensure consumer acceptability, it is essential to maintain
this balance, as an excessive amount of bitterness can diminish the overall enjoyment
of the drink.No sponso
Dental age estimation: A comparative study of convolutional neural network and Demirjian's method
No full textThe aim of this study is to compare a technique using Convolutional Neural Network (CNN) with the Demirjian's method for chronological age estimation of living individuals based on tooth age from panoramic radiographs. This research used 5898 panoramic X-ray images collected for diagnostic from pediatric patients aged 4–17 who sought treatment at Antalya Oral and Dental Health Hospital between 2015 and 2020. The Demirjian's method's grading was executed by researchers who possessed appropriate training and experience. In the CNN method, various CNN architectures including Alexnet, VGG16, ResNet152, DenseNet201, InceptionV3, Xception, NASNetLarge, InceptionResNetV2, and MobieNetV2 have been evaluated. Densenet201 exhibited the lowest MAE value of 0.73 years, emphasizing its superior accuracy in age estimation compared to other architectures. In most age categories, the predicted age closely matches the actual age. The most inconsistent results are observed at ages 12 and 13. The results highlight correspondence between the age predicted by CNN and the Demirjian's approach. In conclusion, the results show that the CNN method is adequate to be an alternative to the Demirjian's age estimation method. We suggest that convolutional neural network can effectively optimize the accuracy of age estimation and can be faster than traditional methods, eliminating the need for additional learning from experts.No sponso

burnout and hopelessness scale scores of those with higher income status were lower than those
with lower income, marital life scale, quality of life scale environmental and psychological
health sub-dimension scores were found to be higher. While married people had higher quality
of life scale and marital life scale scores than singles, hopelessness scores were found to be
lower. While it was observed that the marital life and quality of life scores of the parents whose
child's nutrition process was affected during the COVID-19 process were lower, their
hopelessness levels were higherNo sponso
Advantages of pulse-train excitation in narrow-band terahertz generation: mitigation of undesired nonlinear effects
No full textIn this work, we have studied the limitations of narrowband multi-cycle (MC)
terahertz (THz) generation via optical rectification (OR) in periodically poled lithium niobate
(PPLN) crystals. Detailed investigation of the transmitted beam profile, THz conversion efficiency
(CE), and parasitic second-harmonic generation (SHG) strength as a function of incident pump
beam size showed that Kerr-lensing is a significant bottleneck in the efficiency scaling of MC
THz generation. We have also demonstrated that compared to the usage of a single pump pulse,
excitation of the PPLN crystal via a pulse train, not only boosts up THz CE and narrows down
the bandwidth of the achieved THz beam but also helps to mitigate the effect of undesired
nonlinearities, such as Kerr-lensing and parasitic SHG.No sponso
Telerehabilitation Methods in Orthopedic Rehabilitation
No full textTelerehabilitation is providing medical rehabilitation services remotely using electronic information and communication technologies. It means the two-way transfer of images of the physiotherapist and the patient to each other. In recent years, telerehabilitation practices have the potential to be a cost-effective alternative for patients living in remote areas and having problems reaching the hospital. For this reason, it is frequently used for its benefits, such as reducing patient travel barriers, providing flexible exercise hours, and facilitating better integration of skills into daily life. Telerehabilitation services can be applied to all patient populations and healthcare settings. Disorders such as osteoarthritis, osteoporosis, fractures, rheumatoid arthritis, and waist and neck pain, which have an essential place among orthopedic diseases, are some of the significant public health problems that are increasingly common all over the world. Tele-orthopedics, one of the methods used in the follow-up of orthopedic diseases, is one of the essential methods that has become widespread in patients. Telerehabilitation methods and training are used to rehabilitate orthopedic and musculoskeletal diseases. These methods include videos, telephone, videoconferencing platforms, or virtual reality. It is reported in the literature that telerehabilitation in orthopedic diseases will reduce healthcare costs, improve compliance with treatment, and provide physical and mental recovery. This section discusses current telerehabilitation approaches in orthopedic diseases’ operative and nonoperative periods. In addition, the extent to which telerehabilitation applications are used with current literature information will be examined.No sponso
Borç ödemeden aciz sebebiyle mirasçılıktan çıkarma halinde çocuk mallarını yönetme yetkisinin sınırlandırılması
No full texthttps://www.jurix.com.tr/article/38367?u=0&c=0Borç ödemeden aciz sebebiyle mirasçılıktan çıkarma, TMK m. 513 hükmünde düzenlendiği üzere (krş. Art. 480 ZGB ve § 2338 BGB) mirasbırakanın, borca batık altsoyunu saklı payının yarısından muaf tutarak onun doğmuş veya doğacak çocuklarını bu miktar bakımından mirasçı kıldığı maddî anlamda bir ölüme bağlı tasarruftur. Diğer bir ifadeyle, murisin, torunlarını borca batık çocuğundan koruması ve mallarını doğmuş veya doğacak torunlarının kazanması için vasiyet etmesi imkânıdır. 4721 Sayılı Türk Medeni Kanunu m. 352/I hükmü uyarınca çocuğun yasal temsilcileri hesap ve güvence vermeksizin çocuk mallarını yönetmek hakkına ve yükümlülüğüne sahiptirler. Bununla birlikte TMK m. 343/II hükmü uyarınca ana ve babanın çocuk malları üzerindeki yetkisine bakılmaksızın çocuk, borçlarından malvarlığı ile sorumludur. Hak ehliyetine sahip her kişi gibi çocuğun da malvarlığı ile sınırsız sorumlu olması, maddî durumu kötü olan yasal temsilcinin borçlarının çocuk mallarına sirayet etmesi tehlikesini de doğurmaktadır. Koruyucu ıskat ile mirasbırakanın ulaşmak istediği sonuç torunlarını yasal temsilcisinin borçlarından korumak ve onlara bazı aktif değerleri ihdas etmektir. Fakat TMK m. 352 vd. hükümlerinde çocuğun yasal temsilcisine çocuk mallarının yönetimi bakımından geniş yetkiler tanınmıştır. Çocuğun borca batık haldeki yasal temsilcisinin çocuk mallarını yönetme yetkisinin bu denli geniş olması da bir diğer tehlike sebebidir. Ana babanın yönetim hakkına hâkim müdahalesi ise TMK m. 360 hükmünde düzenlenmiştir. Bu yetkiler TMK m. 363 hükmünde ana ve baba vekil gibi sorumlu tutularak sınırlandırılmıştır. TMK m. 361 hükmünde çocuk mallarının tehlikeye düşmesi halinde hâkim kararıyla çocuk mallarının yönetiminin bir kayyıma devredilmesi düzenlenmiştir. Buna göre çocuk mallarının tehlikeye düşüp düşmediğini hâkim takdir edecektir. Bu yola kimin hangi hallerde başvuracağı hükümde açıkça düzenlenmemiş olup yoruma muhtaçtır. Kanımızca koruyucu ıskata yönelik ölüme bağlı tasarrufta bulunulması hâkimin takdir yetkisini kullanmasına ihtiyaç duyulmaksızın TMK m. 361 hükmünün uygulanmasına hukukî dayanak teşkil etmektedir. Bu durum favor testamenti ilkesinin de bir gereğidir.No sponso
The business start-up procedures and costs for entrepreneurs
No full textEntrepreneurs may encounter various difficulties when launching a new business. A business setup process can be quite straightforward in some nations and be challenging in others, particularly with regard to the amount of procedures to register a business and procedural costs. This study uses data from multiple nations to evaluate and the number of the required procedures and their costs associated with launching a business over time. 10 years of data from 171 different nations are included in the research sample. The study has two main variables. The findings show that there is a positive and significant relationship between the amount of business start-up procedures and procedural costs. The analysis of the data history also reveals that the time-consuming aspects of business start-up procedures and procedural costs for starting a business have shown a global downward trend over the years. Through a quantitative analysis, this study has demonstrated in the literature that countries consider the importance of making remedial arrangements to encourage entrepreneurship. Facilitating the entrepreneurship process and paving the way for new investments worldwide is essential for the development of national economies. Countries are expected to further improve current policies for entrepreneurial activity.No sponso
