The scoping review of systematic instruction literature for individuals with disabilities: trends in Türkiye from 1983 to 2022
No full textThis study used a scoping review to examine the systematic instruction studies for individuals with disabilities published in the last four decades (1983–2022) in Türkiye. We included 332 single-case and 61 group experimental studies. We collected inter-rater reliability data for 30% of the studies and determined that the mean of inter-rater coefficients was 99.2%. The findings indicate that the studies have been mainly self-funded and performed by one or two special education researchers. Studies conducted with single-case studies were more prevalent than group experimental studies. Male participants were more than females, and more school-age children than infants and adults. Participants with intellectual disabilities and autism were the most frequently involved, and school-related academic and cognitive skills were the most commonly targeted. The most frequently used interventions were response prompting strategies, strategy instruction, video modelling and prompting, and direct instruction. Finally, we discussed the findings and made recommendations for practice and future research
Design and detailed electrical characterization of MoO3 supported Au/n-Si junction diodes
No full textIn this study, the effect of molybdenum trioxide (MoO3) nanopowder as a thin film layer on theperformance of junction diodes was investigated and the fabrication of Au/MoO3/n-Si/Al devicestructure with this material was achieved. In the experimental process, Al was thermally depositedon one surface of the silicon wafer and annealed at 450 °C for 10 min to establish anohmic contact. A thin film of MoO3 approximately 15 nm thick was deposited on the n-Si surfaceby thermal evaporation at a 10−7 Torr high vacuum. On top of this layer, a 100 nm Au layer wasdeposited by thermal evaporation using a circular mask. The reference Au/n-Si/Al diode wasfabricated under identical conditions without the MoO3 layer to evaluate the influence of the oxideinterlayer on the device characteristics. The electrical performance of the devices was characterizedthrough I–V measurements at 300 K. The diode parameters, including the barrierheight (BH) and the ideality factor (IF), were extracted using the TE theory and further analyzedusing the Cheung and Norde techniques. The BH (Φb) and IF (n) values of the reference Au/n-Si/Al diode were calculated as 0.65 eV and 2.06, respectively. In contrast, the diodes with theMoO3 interlayer exhibited Φb values ranging from 0.70 to 0.73 eV and n values between 1.69and 1.73. The increased ideality factor was attributed to the influence of series resistance, whilethe variations in BH were related to the properties of the MoO3/n-Si interface. Among the devicesfabricated, the diode with the best performance (referred to as device 2) showed an IF of1.69 and a BH of 0.73 eV. This device was selected for detailed analysis and its characteristicswere further examined using the Cheung and Norde methods. In addition, C–V, G-V, and Z-Vmeasurements at various frequencies were used to derive key device parameters, particularlythe BH, highlighting the role of frequency-dependent behavior</p

No full textPrimula longipes subsp. bayburtensis Sefali, Yapar & Demir (Primulaceae): A new taxon from north-eastern Anatolia, Türkiye
No full textThe new taxon, Primula longipes subsp. bayburtensis Sefali, Yapar & Demir, subsp. nov. (Primulaceae) is described and illustrated from Bayburt Province, Türkiye. It is morphologically assigned to Primula sect. Crystallophlomis based on its long scapes, lanceolate and denticulate leaf with long petiole and hairless habit, fruits longer than calyx and covered by farina on the scape. This new taxon is similar to Primula longipes and P. nivalis subsp. turkestanica; it can also be easily distinguished by its calyx divided ratio, thurm flowers (unwidened corolla tube shape and length) and capsules (length) futures

No full textInvestigation of changes in goblet cells in the digestive tract of Van fish during reproductive migration Istraživanje promjena vrčastih stanica probavnog sustava ribe Van tijekom migracije u vrijeme mriještenja.
No full textLake Van is among the largest soda lakes in the world. The Van fish is an endemic species of the carp family living in Lake Van. In order to breed, they migrate in flocks to the streams flowing into the lake between April and July, depending on the water temperature. After the fish lay their eggs in the fresh water, they return to Lake Van. In this study, goblet cells in the digestive tract of Van fish during reproductive migration were labeled with periodic acid–Schiff, Alcian Blue pH 2.5, Alcian Blue pH 1.0, Alcian Blue pH 0.5, and aldehyde fuchsin dyes. Changes in cell localization, density, and area were determined in different parts of the digestive tract in goblet cells containing neutral, acidic, O-sulfate ester, strongly sulfated, and sulfated acidic glycoconjugate. In the esophagus, goblet cells were only observed in the fish from Lake Van. Although goblet cell size and density varied in other parts of the digestive tract, all glycoconjugates were labeled. In the digestive tract of fish from the lake, the goblet cell areas were large, but the cell density was low, whereas the situation in the digestive tract of fish sampled from the streams was the opposite. It was concluded that the main reason for the goblet cell change in the digestive tract of Van fish is related to its feeding behavior and habitat
