Alternatif Bir Modern Amerikan Sanatı: David Park ve Körfez Bölgesi Figüratif Resmi
Authors: Koyunoğlu Ö. Eren
Published: August 2024

Amerika’nın Batı Yakası’nda bulunan ve San Francisco’nun merkezi olduğu Körfez Bölgesi, 20. yüzyıl başlarında modern sanat akımlarının etkisine girmiş ve 1940’lı yıllara gelindiğinde Amerikan modern sanatın gelişimine katkı sağlayacak bir pozisyona gelmiştir. 1930’larda Diego Rivera ve Hans Hofmann gibi yabancı sanatçıların etkisiyle Toplumsal Gerçekçilik ve Avrupa modern sanat yaklaşımlarını deneyimleyen Körfez Bölgesi, 1940’larda bölgeye gelen Sürrealizm’in etkisiyle 1940’ların ikinci yarısında özgün bir modern Amerikan sanatı olan Amerikan Soyut Dışavurumculuğu’nun örneklerini vermeye başlamıştır. Clyfford Still’in radikal sanat üretimi ve eğitim tarzının öncülüğünde bu akımın Batı’daki merkezi haline gelen San Francisco, 1950 yılına gelindiğinde Still’in bölgeden ayrılması ile sanatsal yönünü değiştirmiştir. 1949 yılından itibaren erken döneminde Still’in etkisiyle yaptığı soyut sanatı sorgulamaya başlayan David Park, soyutla figüratif yaklaşımı birleştiren özgün bir anlayış geliştirerek bölgedeki 1950 sonrası dönemin ana figürü olmuştur. Park’ın dönemin alternatifsiz “doğru” kabul edilen üslubunun bir çeşitlemesini yapmak yerine ona alternatif olarak öne sürdüğü bu yaklaşımı bir süre sonra bölge sanatçılarının büyük çoğunluğu takip etmeye başlamıştır. Körfez Bölgesi Figüratif Hareketi ismini alan bu yaklaşım bölgenin kültürel ve estetik özellikleriyle şekillenmiş ve Amerikan Soyut Dışavurumculuğu’nun otoritesini kırmayı başararak 1940’lı yıllar ile 1960’lı yıların sanatsal hareketleri arasında bir köprü oluşturmuştur. Bu makale, David Park’ın ve yarattığı Körfez Bölgesi Figüratif Hareketi’ni, bölgenin sanatsal dokusu ve tarihi açısından inceleyip değerlendirerek, özgün Amerikan Modern Sanatı içindeki yerlerini ve önemlerini ortaya koymaya çalışmaktadır. Makalede Körfez Bölgesi’nin kendine bölgesel ve kültürel özellikleri açıklanmış, bölgenin sanat ortamının süreçleri değerlendirilmiştir. Bu değerlendirme sonucunda Amerikan Soyut Dışavurumculuğu’na alternatif olarak ortaya çıkan Körfez Bölgesi Figüratif Hareketi’nin neden ve nasılları, David Park ve eserleri üzerinden ele alınmıştır.

Published: August 2024

The aim of this study was to examine the incubation characteristics of hatching eggs from one of the widely distributed hybrid combinations of classic broilers globally and to trace the dynamics of their changes depending on the age of the parental flock. The study covered a 12-year period - between 2011 to 2023. The share of quality chicks hatched ranged from 76.8% to 91.6%, with average values of 84.1-84.3%, while the share of culled chickens was within the normal range (0.4 to 1.7%). The proportion of culled eggs during candling on the 7th day varied between 4.3% and 14.7%, with average values of 7.64-8.24%. With the increase in the age of the parental flock, there was a stable tendency to increase the share of culled eggs at the first test egg cull, particularly due to the increase of the share of infertile eggs. The age of the parental flock determined more than 38% of the manifestation of the egg fertility trait and about 45% of that of quality chicks. Its influence on total embryonic mortality was significantly weaker (R2= 0.1456). The study of the relationship between the traits “share of quality chicks” and “share of infertile eggs” showed that in the examined dataset, the correlation between them was moderate, negative (r= -0.472±0.100 at P

The Mediterranean region in Türkiye is noted for the production of cucurbits and other vegetables. As such, the aim of this study was to sample symptomatic cucurbits crops from open fields and greenhouses where there is active cultivation of these crops. Young shoot, leaves, and fruits exhibiting virus-like symptoms (yellowing, mosaic, necrotic) were collected. Out of 968 plant samples collected and tested through RT-PCR and PCR, 949 were discovered to be infected with several viruses. The identified virus diseases included ZYMV, WMV, PRSV, SqMV, CGMV, CYSDV, BPYV, CABYV, ToLCNDV and CMV. In terms of hosts exhibiting a high incidence of virus infections, cucumber (363 samples), squash (277 samples), melon (201 samples), and watermelon (108 samples) emerged as the top four hosts. Additionally, viruses with notable high incidences in the collected samples, as recorded through molecular testing in decreasing order included ZYMV at 28.1%, CYSDV at 15.5%, and WMV at 14.4%. Also, 90% of samples collected from open fields had single or multiple infection. In contrast, 26.4% of samples from greenhouses exhibited mosaic symptoms and 74.6% showed yellowing symptoms. Notably, MNSV and BPYV, were detected in these samples. The samples also exhibiting mixed infections predominantly displayed mosaic symptoms, including mixed infections such as ZYMV with WMV, ZYMV with CMV, CMV with WMV, and CMV with PRSV. In contrast, samples obtained from open fields showed a higher prevalence of yellowing symptoms, such as ToLCNDV with CMV, ToLCNDV with ZYMV, ZYMV with CMV with CYSDV, and ZYMV with CMV with CVYV.
Expression profiling of BSD domain-containing genes in apricot during different developmental stages
Authors: Kıyak Ali
Published: August 2024

Plant transcription factors are evolutionarily conserved proteins that play an important role in the transcriptional regulation of gene expression by binding to their specific DNA sequences. BSD (mammalian BTF2-like transcription factors, synapse-associated proteins, and DOS2-like proteins) transcription factors are conserved in various species, from protozoa to humans, and are characterized by a typical BSD domain. However, little information is available about their possible roles in plant growth and development, and to date, members of this transcription factor family have not been systematically identified and analyzed in apricot. In this study, two BSD domain-encoding genes were identified in the apricot genome. Expression profile analysis by RT-qPCR revealed that both genes participate in different developmental stages of three different organs in apricot. PaBSD1 was expressed higher than PaBSD2 only in the stamen. Moreover, PaBSD2 was higher expressed than PaBSD1 in four different fruit stages, young leaf, leaf bud, sepal and petal. This study reveals the critical roles of BSD transcription factors in apricot development, with PaBSD1 showing higher expression in stamen and PaBSD2 in various fruit stages and leaf tissues. These findings provide a foundation for future functional studies and apricot breeding programs.

Published: August 2024

Objective: To detect any possible illnesses, such as syphilis, and stop them from spreading through transfusion, screening blood donors is crucial. Study Design: Cross-sectional Retrospective Research study. Setting: Four RBCs and the sixteen associated hospital-based blood banks (HBBBs) that are spread over Sindh's various areas. Period: January 2022 to December 2022. Methods: Employing non-probability convenience sampling was carried out. We collected data from Sindh province's Regional Blood Centers (RBCs) and Hospital Based Blood Banks (HBBBs), dispersed throughout the province. Sindh Blood Transfusion Authority (SBTA)'s ethical committee approved the study. To screen selected blood donors for Syphilis, the Chemiluminescence Immunoassay Analyzer (CLIA) was used. Data from the study were summarized using simple percentages after they were statistically examined. Results: With 171,725 male donors and 1,460 female donors, men comprised the bulk of the 173,185 blood donors. Syphilis turned up in 2.5% of the male donors, resulting in an additional 4,311 cases. On the other hand, just 18 (1.2%) of the female donors had a positive syphilis test. The gender distribution of cases with positive Syphilis indicates a notable difference in its frequency between people of both sexes. The age group of 25 to 40 years old accounted for the largest proportion of syphilis cases among blood donors. Conclusion: One of Sindh's biggest public health concerns is the high incidence of syphilis among blood donors. Additionally, the results show that the incidence of syphilis varies by gender. Furthermore, there are considerable age range differences in the distribution of syphilis cases. These results highlight the need for increased screening and preventive programmes, especially in areas with higher incidence rates. Given the high frequency of syphilis among Sindhi red blood cell donors, this could point to a greater number of cases in the overall community.

Published: August 2024

Screen-printed carbon electrode (SPCE) is one of the most interesting designs to combine a working (from carbon based material), reference, and counter electrode in a single-printed substrate. SPCE has been used in many electrochemical measurements due to its advantages for analysis in microscale. This paper summarises the main information about SPCE fabrication from the material and fabrication technique aspect on the flat substrate based on the work that has been published in the last 30 years. The success of SPCE fabrication is highly dependent on the composition of conductive ink which consists of conductive materials, binder, and solvents; substrate; and fabrication techniques. Among the carbon-based materials, the most widely used for SPCE fabrications are graphite, graphene, and carbon nanotubes. The frequent binder used are polymer-based materials such as polystyrene, polyaniline, poly 3,4-ethylenedioxythiophene:polystyrene sulfonate (PEDOT:PSS), and polyvinyl chloride. The solvents used for SPCE fabrication are varied including water and various organic solvents. The main characteristics of the SPCE substrate should be inert in order to avoid any interferences during electrochemical measurements. The screen printing and inkjet printing technique are preferred for SPCE fabrication due to easy fabrication and the possibility for mass production of SPCE.

Published: August 2024

The recovery of Au(III) in the Au/Cu/Mg system from mercapto-silica hybrid coated magnetite (SH/Fe3O4@SiO2) adsorbent has been investigated. This adsorbent characterized using FT-IR to determine functional groups, crystallinity study using XRD, surface morphology using SEM, material compositions with XPS, surface area using nitrogen adsorption, and TGA to study thermal stability. Adsorption of metal ions carried out with batch system for 30 minutes at a pH of 3. In the Au/Cu/Mg multi-metal system, Au(III) ions were easily desorbed (approximately 85%) by SH/Fe3O4@SiO2 adsorbent based on HSAB (Hard Soft Acid Base) theory that Au(III) ion is a softer metal than Cu(II) and Mg(II) where Au(III)>Cu(II)>Mg(II). The recovery of Au(III) ions was easily desorbed using thiourea 7% in 0,1 M HCl solution with the percentage of 79%. The process of SH/Fe3O4@SiO2 adsorbent separation after adsorption and recovery was very easy. The adsorbent could perfectly separate in 5 minutes using an external magnet. The SH/Fe3O4@SiO2 adsorbent can be reused on the adsorption-desorption process of Au(III) in the Au/Cu/Mg system approximately four times of cycle reactions.

У статті розроблені методологічні аспекти створення систем акустичного моніторингу прольоту засобів повітряного нападу (АМПЗПН) та їх інтеграції в систему ситуаційної обізнаності про повітряну обстановку (спеціальне програмне забезпечення “Віраж-Планшет”). Серед нових перспективних альтернативних джерел інформації про повітряну обстановку застосовуються акустичні датчики. Тож, автоматизований збір, аналіз, відображення та обмін інформацією від акустичних датчиків про прольоти засобів повітряного нападу противника в інформаційних (автоматизованих) системах є актуальним науково-технічним завданням. Проведено аналіз стану справ з розробки систем АМПЗПН в Україні. Зазначено, що серед проектів таких систем можна відмітити системи “еРакета” та “Звук”. Запропоновані загальні вимоги до їх побудови, наведено варіант структурної схеми їх побудови. Зазначено, що найскладнішим та найголовнішим при розробці системи АМПЗПН є розробка підсистеми розпізнавання акустичного сигналу та класифікації повітряного об’єкта. При цьому, дана підсистема повинна мати повну базу даних портретів акустичних сигналів засобів повітряного нападу противника. Показано, що на роботу перспективних систем АМПЗПН суттєво впливає швидкість розповсюдження звукових хвиль у порівнянні зі швидкістю повітряних об’єктів. Проведено аналіз часових затримок, що можуть виникати в системах ситуаційної обізнаності про повітряну обстановку при виявленні засобів повітряного нападу. В середньому вони складають 29 секунд при дальності виявлення 10 км. За цей час крилата ракета пролітає в середньому від 5,83 км до 7,84 км, а безпілотний літальний апарат – 1,14 км. При використанні функціоналу перевірки інформації (модерації подій) оператором системи часові затримки збільшуються. Кожна хвилина обробки збільшує дальність прольоту крилатої ракети від 12 км до 17,45 км, а безпілотного літального апарата – 2,34 км. Розроблено загальну схему та протокол отримання (видачі) інформації про повітряну обстановку від системи АМПЗПН противника в систему ситуаційної обізнаності про повітряну обстановку “Віраж-Планшет”.

Authors: Vinogradova M. M.
Published: August 2024

The article examines a new object of forensic economic examination – cryptocurrency. The author provides classic definitions of an object of forensic examination and establish the differences of cryptocurrency from the traditionally understood objects of both forensic examination in general and economic examination in particular. The main difference of cryptocurrency from other currencies and objects of investigation is its virtual nature, lack of affiliation with the material world. Two main points of view on the essence of cryptocurrency are analyzed: as a basis and tool for the development of new effective forms of payments, exchange of goods, and as an object and instrument of criminal activity. A definition of cryptocurrency is given as interpreted by the FATF – Financial Action Task Force. It is identified which issues related to the circulation of cryptocurrency can be attributed to the competence of a forensic expert-economist, and which – to the field of computer forensics. The author also describes the features of cryptocurrency that must be taken into account when considering it as an object of forensic economic examination.
Regulations on Diversion in the Settlement of Children in Conflict with the Law: A Comparative Analysis of Positive Law and Islamic Criminal Law
Authors: Lubis Suci Dini , Lubis Syaddan Dintara
Published: August 2024

Children who commit crimes must have their rights protected to ensure their survival and well-being. This study aims to apply diversion regulations in resolving cases of children in conflict with the law at the Women and Children's Services Unit of the Criminal Investigation Department in the Labuhanbatu Police Department to ensure the provision of restorative justice. This empirical legal study collected data through interviews with the Labuhanbatu Police Department. Findings indicate that diversion regulations are detailed in Law No. 11 of 2012 concerning the Juvenile Criminal Justice System. According to Islamic criminal law, if a child commits a crime, the punishment should be educational and involve al-shulhu (reconciliation). While diversion is carried out with a restorative justice approach, many juvenile offenses are not entirely diverted and are often processed further in the legal system. The practice of reconciliation for juvenile crimes in Labuhanbatu involves the upah-upah ceremony, which aligns with the concept of al-shulhu. Factors that prevent juvenile offenses from being resolved through diversion include cases of theft, embezzlement, and assault. This study recommends that diversion be mandatory for juvenile offenders at the stages of investigation, prosecution, and trial to resolve juvenile criminal cases
A PWM Adaptive Sliding Mode Observer for Charge Control of Lithium Ion Battery

Published: August 2024

An adaptive sliding mode control (SMC) based on PWM and an observer scheme for predicting the state of charge (SOC) of lithium-ion batteries is proposed. The control scheme is developed for a dc-dc buck converter used in regulated charge control of lithium-ion batteries. Unlike many estimation schemes where the converter’s output voltage is predetermined and the nonlinearities ignored, the proposed scheme estimates the buck converter’s output voltage, SOC, and nonlinearities in terms of errors in parameters. The stability of the proposed scheme is guaranteed by the Lyapunov method. The simulation was carried out in the Simulink in the MATLAB environment to transition from constant current charging mode to constant voltage charging mode. The results obtained from both modes in the Simulink in the MATLAB environment have shown that the dynamic control system of the SMC is asymptotically stable with excellent robust recovery features to sudden variations in input and un-modelled load.

Published: August 2024

Pedestrian detection is well known as one of the most important applications in computer vision. However, reliable pedestrian detection is difficult due to a variety of factors, including changing size of pedestrian characteristics and crowded backgrounds. This study aims to evaluate and compare the pedestrian detection performance of three different types of classifiers: Random-Forest (RF), Convolution-Neural-Network (CNN), and Support-Vector-Machine (SVM). The presented methodology involves using You_Only_Look_Once (YOLOv8) architecture for object segmentation and the Histogram of Oriented Gradients (HOG) for feature extraction. Then, RF, CNN and SVM classifiers are trained and tested using the extracted HOG features. Using the EPFL pedestrian dataset, the experiment showed that the CNN model returned the highest results which had a speed of 0.42s and an accuracy percentage of 93.34%. Compared to SVM and RF, CNN provides a high detection speed and accuracy. RF has the slowest detection speed, while SVM has the lowest detection accuracy. This study gives useful information regarding the efficacy of these classifiers in detecting pedestrians under various weather circumstances, and the findings show that CNNs can achieve high accuracy while maintaining remarkable detection efficiency.

This study aims to analyze the difference in participation of small businesses in government procurement of goods and services before and after the implementation of a Presidential Regulation Number 12 Year 2021. Based on the theory of set aside policy, it is anticipated that the participation of small businesses will increase by reducing competition with non-small businesses. The research employs a quantitative method using data on construction job tenders in West Papua and applies nonparametric difference tests analysis. The results indicate that there is no significant difference in the average participation of construction job tenders in West Papua before and after the implementation of the Presidential Regulation Number 12 Year 2021. The implication suggests the necessity for additional government policies to enhance the participation of small businesses to achieve the goals of government procurement of goods and services more expeditiously.
