Kedilerde medetomidin/ketamin ve ksilazin/ketamin anestezisinin ve bunların atipamezol ile etkilerinin ters çevrilmesinin oküler ve anestezi izlem parametreleri üzerindeki etkileri
Full text linkThe aim of this study was to investigate the impact of the general anesthetic drug ketamine and premedication agents
medetomidine and xylazine, and their reversal by atipamezole, on monitored anesthesia care values and ocular parameters such as
intraocular pressure, horizontal pupillar diameter, and Schirmer tear test in cats. A randomized, single-blinded study was conducted.
Twenty intact female cats (weiging between 2.2 and 3.6 kg, and 0.5 to 5.5 years of age) referred for ovariohysterectomy (OHE) procedure
by the owners at regular intervals over 4 months were included in the study. The cats were randomly divided into two groups containing
10 animals in each group. The cats were premedicated with medetomidine 80 µg/kg intramuscular in group 1 while the cats in the 2nd
group were premedicated with xylazine hydrochloride 2 mg/kg intramuscular. After the OHE procedure was ended, anesthesia regimes
were reversed by using atipamezole 200 µg/kg intramuscularly. Monitoring of respiration rate, heart rate, mean arterial pressure,
peripheral arterial oxygen saturation, and body temperature were conducted using a patient monitor at T0, T1, T2, T3, and T4 time
points. Both groups showed declines in intraocular pressure and increases in horizontal pupil diameter after anesthesia induction (T0
vs. T1, all, P<0.05); however, the chancing and recovery pattern of intraocular pressure and horizontal pupil diameter showed
intergroup difference. In conclusion, xylazine/ketamine is more effective than medetomidine/ketamine in attenuating the intraocular
pressure, increasing the horizontal pupil diameter, and alteration the monitored anesthesia care response in the general anesthesia.: Bu çalışmanın amacı, genel anestezik ilaç ketamin ve premedikasyon ilaçları medetomidin ve ksilazinin; ve bunların
etkilerinin atipamezol ile tersine çevrilmesinin göz içi basıncı, yatay pupil çapı ve Schirmer gözyaşı testi gibi kedi oküler ve anestezi
izlem parametreleri üzerindeki etkilerini araştırmaktı. Rastlantısal, tek tarflı kör bir çalışma yürütüldü. Sahipleri tarafından 4 aylık süre
içerisinde ovaryohisterektomi operasyonu için başvurulan 20 erişkin dişi kedi (2,2 ila 3,6 kg ve 0,5 ila 5,5 yaş arasında) çalışmaya dahil
edildi. Kediler, her grupta on kedinin olduğu iki gruptan birine rastlantısal olarak dahil edildi. Grup 1'de kediler kas içi 80 µg/kg
medetomidin ile premedike edilirken grup 2 deki kediler kas içi ksilazin hidroklorür 2 mg/kg ile premedike edildi. Ovariohisterektomi
işlemi bittikten sonra anestezik etki kasiçi atipamezol 200 µg/kg kullanılarak ters çevrildi. Solunum sayısı, kalp atım hızı, ortalama
arter kan basıncı, periferik arteriyel oksijen düzeyi ve vücut ısının izlenmesi T0, T1, T2, T3 ve T4 zaman noktalarında hastabaşı monitör
kullanılarak gerçekleştirildi. Her iki grup da anestezi indüksiyonundan sonra istatistiki olarak önemli olan göz içi basıncında düşüş ve
yatay pupil çapında artış gösterdi (T0'a karşı T1, tümü, P<0,05); bununla birlikte, göz içi basıncı ve yatay pupil çapının anestezideki
değişim ve başlangıç değerine dönüşler gruplar arası farklıydı. Sonuç olarak ksilazin/ketamin kombinasyonu, genel anestezide göz içi
basıncını azaltmada, yatay pupil çapını artırmada ve izlenen anestezi bakım parametrelerini değiştirmede medetomidin/ketamin
kombinasyonundan daha etkilidi
An improvement of current driving and electrical conductivity properties incovetics
Full text link: Compared to pure Cu, Cu lattice retaining carbon atoms, called a covetic material, can have better
electrical conductivity. Furthermore, the incorporation of carbon nanostructures into Cu-alloys could improve
the mechanical properties of Cu-alloys. In the simulation study, we investigated Joule heating due to applied DC
current on molten Cu metal concerning how to improve current density of covetic materials. In addition, we will
discuss interfacial effects on covetic-metal electrodes to meet better current driving performance. The covetic
composite excited at one electrode (width = 10 nm) has a higher current drive capability as a value of 3.54 107
A/m2
, for 1000 A current at a temperature of 1073.2 K, this value is a constant while temperature is changing
up to 1573.2 K. We measured the conductivity of the proposed covetic materials at various carbon nanotube
densities at room temperature. Experimental results show the lowest resistivity value accomplished after mixing
and temperature annealing as a value of 1.78 10−8 Ω.m, where the covetic sample has 1.27% carbon nanotube
density, and that the electrical conductivity is superior to that of Cu-carbon nanotube composites previously

Pseudomonas putida KT2440 induces drought tolerance during fruit ripening in tomato
Full text linkThe current study investigated the effects of Pseudomonas putida strain KT2440 on the drought tolerance of tomato plants during fruit maturation. Plants at the ripening stage of the mature-green were not watered for 20 days to promote drought stress. Concentrations of photosynthetic pigments were determined. Bacteria-soaked tomato plants (BSS) had higher levels of chlorophyll and carotenoids than non-soaked plants (DWS) under stress conditions. Compared to the DWS, stomatal conductance, lipid peroxidation, and hydrogen peroxide content in the BSS plants decreased under drought stress. The ascorbate peroxidase (APX), catalase (CAT), and peroxidase (POD) activities increased in BSS plants compared to DWS under drought stress. Furthermore, the number and weight of fruits in both DWS and BSS plants was reduced by the stress, but the reduction in BSS plants was lower than in DWS plants. These results showed that bacteria treatment conferred tolerance to drought stress in tomato plants by reducing the peroxidation extent of polar lipids (PLs), increasing photosynthetic pigment content, and activities of the antioxidant enzymes in the leaves. Therefore, P. putida KT2440 has supported high fruit yield under drought stress as a biotic tolerance elicitor for this plant stress
The unit folded normal distribution: a new unit probability distribution with the estimation procedures, quantile regression modeling and educational attainment applications
Full text linkIn this paper, we develop a continuous distribution on the unit interval characterized by the distribution of the absolute hyperbolic tangent transformation of a random variable following the normal distribution. The lack of research on the prospect of hyperbolic transformations providing flexible distributions on the unit interval is a motivation for the study. First, we study it theoretically and discuss its properties of interest from a modeling point of view. In particular, it is shown that the proposed distribution accommodates various levels of skewness and kurtosis. Then, some statistical work is performed. We investigate diverse estimation methods for the involved parameters and evaluate their performance through two simulation studies. Subsequently, the quantile regression model derived from the proposed distribution is developed. Two real-world data applications of interest are provided. The first application is about the univariate modeling of the percentage of the educational attainment of some countries, which is one indicator of the education topic of the Better Life Index (BLI) of the Organization for Economic Co-operation and Development (OECD) countries. The second application is to explain the relationship between the percentage of educational attainment of some countries with one indicator of the work-life balance, safety, and health topics of BLI via median quantile regression modeling. For the considered data sets, the proposed distribution and quantile regression models show that they have better modeling abilities than competitive models under some comparison criteria. The results also indicate that covariates are (statistically) significant at any ordinary level of significance for the median response
Content and quality of online videos about ostomy pouch changes: a descriptive study
No full textBACKGROUND: Many health-related videos are available online. One type of health-related video is related to stoma pouch change. However, a system to evaluate the quality and content of these videos is lacking. PURPOSE: To evaluate the content and quality of YouTube videos on colostomy pouch change. METHODS: A descriptive study was carried out by searching for videos on March 15, 2021, using the key words "colostomy care," "colostomy bag/pouch change," and "ostomy bag/pouch change." A 5-point Global Quality Scale was used to evaluate the quality of the videos, and a 10-point scale was used to evaluate the content. The videos were classified as "useful" or "useless" according to their content and quality scores. RESULTS: A total of 128 videos were found; 94 videos met the criteria and were included in the study. The content of the 94 videos was examined by 2 independent researchers. The overall content score of the videos was 8.24 ± 1.56, and the overall quality score was 3.14 ± 0.97. A total of 66 (70.21%) videos were useful, and 28 (29.79%) videos were useless. The mean scores of useful videos for content (9.09 ± 0.83) and the average Global Quality Scale scores (3.53 ± 0.76) were significantly higher than those of useless videos (6.17 ± 0.90 and 2.25 ± 0.75, respectively; (P < .05). The results showed that 57.6% of the useful videos were uploaded by universities, professional organizations, and health care professionals, and 67.9% of the useless videos were uploaded by patients; the difference was statistically significant (P < .05). CONCLUSIONS: Results indicated that the majority of online videos evaluated were accurate. Most of these videos were uploaded by universities, professional organizations, health care professionals, or medical advertisers. Although there were many limitations to this study, the authors suggest that health care professionals can direct their patients to these sources after hospital discharge. However, future studies are needed.
Silver nanoparticles (AgNPs) in urea solution in laboratory tests and field experiments with crops and vegetables
Full text linkNanotechnology and nanomaterials, including silver nanoparticles (AgNPs), are increas-ingly important in modern science, economics, and agriculture. Their biological activity involvesinfluencing plant health, physiological processes, growth, and yields, although they can also be toxicin the environment. A new fertiliser was made based on a urea solution with a relatively low contentof AgNPs obtained by the reduction of silver nitrate V. Laboratory tests were used to assess theeffect of a fertiliser solution containing 10 ppm AgNPs on the germination of agricultural plant seeds(barley, peas, oilseed rape) and vegetables (radish, cucumber, lettuce) and its foliar application onchlorophyll content, stomatal conductance, and seedling biomass. Field experiments were conductedto assess the effect that a foliar application of 15 ppm AgNPs in working liquid had on physiologicalplant parameters and yields of rape and cucumber. The AgNPs in the tested fertiliser reducedinfestation of the germinating seeds by pathogens and positively affected the physiological processes,productivity, and yields of plants. Plant response depended on plant species and habitat conditions.Reduced pathogen infestation of seeds, higher germination energy, increased chlorophyll content andstomatal conductance, and higher seedling masses all occurred under the influence of AgNPs, mainlyin oilseed rape and cucumber, and especially under thermal stress. The beneficial effect of AgNPson the yield of these plants occurred in years of unfavourable weather conditions. The positiveagricultural test results, especially under stress conditions, indicate that fertiliser produced withAgNPs as an ingredient may reduce the use of pesticides and highly concentrated mineral fertilisers.Such a fertiliser is fully in line with the idea of sustainable agriculture. However, research on theeffects that AgNPs and fertiliser have on the environment and humans should continue
Testing the mediating role of phubbing in the relationship between the big five personality traits and satisfaction with life
Full text linkOrdu University Scientific Research CoordinatorPhubbing refers to an individual giving more attention to their mobile phone when in face-to-face communication with another individual. Research in the area of phubbing is relatively new and is often related to habitual mobile phone use. The aim of the present study was to explore the relationships between phubbing, the Big Five personality traits, and life satisfaction. The mediating role of phubbing in the relationship between personality traits and life satisfaction was also investigated. The sample comprised 292 university students (192 females [65.8%] and 100 males [34.2%]). The age of the university students in the study group ranged from 17 to 28 years and the mean age was 20.05 years (SD = 2.33). Correlation analysis demonstrated that there were significant relationships between life satisfaction, phubbing, communication disturbances, and neuroticism. Phubbing was shown to have a non-significant relationship with life satisfaction. The study also examined the mediating role of communication disturbances in the relationship between neuroticism and life satisfaction. Neuroticism was shown to have a significant effect on communication disturbances, and communication disturbances had a significant effect on life satisfaction. Consequently, communication disturbances had a mediating role in the relationship between neuroticism and life satisfaction
Determining the musculoskeletal problems of academicians who transitioned to distance education during the COVID-19 pandemic
Full text linkBackground: Musculoskeletal disorders are a significant public health issue that negatively affects individuals and society both socially and economically, and increases the cost of care and cure.
Objective: This study aimed to determine the musculoskeletal problems and risk factors of academicians who transitioned to provide distance education during the COVID-19 pandemic.
Methods: The population of this descriptive cross-sectional study included academicians who worked in two public universities in Turkey. Ethical committee approval and institutional permissions were obtained between 1 and 28 February 2021. Data were collected using a personal information form, the Work Environment Evaluation Questionnaire, and the Musculoskeletal Pain Intensity Assessment Questionnaire. The data were analyzed using the number, percentage, independent group t-test, ANOVA test, and linear regression analysis (forward method). The analysis was interpreted at the 95% confidence level and 0.05 error margin.
Results: Of the academicians, 78% were women, 54.6% were married, 80.6% did not regularly exercise, and 73.5% had more workload during the distance education period. Academicians mostly experienced discomfort about their eyes, necks, and waists, and an increase at a significant level was detected in their musculoskeletal system problems during the distance education period. Increasing workload, duration of mobile phone use, active time, having an ergonomic chair, and gender predicted the musculoskeletal system pain intensity by 20%.
Conclusion: Musculoskeletal system problems are a significant public health issue. Academicians should be informed and consulted for the protection of musculoskeletal system health during the distance education period

Asiltürk romanlarında hadiseleri anlatırken bir yandan da tahkiyenin arka planında olayların cereyan ettiği Türkiye'nin sosyal gerçeklerine yer vermiştir. Sade anlaşılır bir üslupla aktarılan eserler; Asiltürk'ün diğer yanı olan sinemacı kimliğinden de nasibini fazlasıyla almıştır. Dünya edebiyatında yaygın olarak bilinse de sinemada bir ilk örnek olan "Büyülü Gerçekçilik" üslubu kendisinin öğrencilik yıllarında çektiği (1987-1991) yurtiçi-yurtdışı festivallerde ilgiyle ve takdirle karşılanan Düş Akıntıları, Özgürlük Tutkusu, Eziyet, Esrime, Bir Aşkın Cenaze Töreni, Göz, Komik Ölüler Ülkesi adlı kısa, Büyülü Gerçekler (2008) ve Akordeon (2010) adlı orta metraj filmlerinde; TRT adına çektiği Kaçakçılar, Geç Gece, Mavi Bavul vd. uzunlu kısalı televizyon filmlerinde (2004-2005) ve Albatrosun Yolculuğu (2013) adlı uzun metrajlı filminde açıkça gözlenebiliyor. Başarılı bir romancı ve senarist olan Attila İlhan gibi Asiltürk de gözlemlerini bir kamera vizörünün hassaslığıyla, romanlarında kullanmıştır. Tahkiyelerdeki yoğun şahıs kadrosu ve kimi zaman kullandığı sinema terimleriyle okuyucunun ilgisini diri tutmaktadır. Asiltürk'ün romanlarında ayrıca şiirden estetiğe, kronolojik tarihten sanat tarihine ve sinemadan tabiat bilgisine kadar, sosyal hayatın gerektirdiği birçok bilgiye rastlamak mümkün... Yazar, eserlerini oluştururken gerçeklikten çok da uzaklaşmadan anlatısını renkli tablolar halinde bilgilerle pekiştirerek yapmakta. Okuyucu bir yandan roman kişilerinin serüvenini merakla takip ederken; diğer yandan da renkli görüntüler içindeki şiirsel anlatımın zevk ve ahengini yaşar. Asiltürk'ün anlatısı, bir tezin konusu olabilecek kadar dolu ve değerlendirmeye açıktır. Romanları mutlaka dikkatli bir şekilde okunmalıdır.Cengis Asiltürk is one of the new generation representatives, novelists and film writers of the "Magical Reality Movement" in Turkey. The author presents various sections from the lives of the bourgeois families in his novels. While doing this, we see places that we can call very rich, together with educated conscious people among rich and diverse staff. On the one hand, the author conveys the life stories of the bourgeois families, on the other hand, the longing from the countryside to the city and the flow from the village to the city with striking messages. While Cengis Asiltürk narrated the events in his novels, he also included the social realities of Turkey, where the events took place in the background of the narration. Works with a simple and understandable style; The other side of Asiltürk, he has had his share of the identity of a filmmaker. Just like Atila İlhan, who is a successful novelist and screenwriter; Cengis Asiltürk also used his observations in his novels with the precision of a camera viewfinder. It also keeps the reader's interest alive with its dense cast of characters in the narrations and the cinematic terms it sometimes uses. In Asiltürk's novels, it is also possible to come across all kinds of information required by social life, from poetry to aesthetics, from chronological history to art history, from cinema to natural knowledge. While creating his works, the author does not stray too far from reality, reinforcing his narrative with information in colorful tables. While the reader is curiously following the adventures of the characters of the novel; On the other hand, he is enchanted by the harmony and pleasure of poetic expression in colorful images. Cengis Asiltürk's novels are so full and open to evaluation that they can be the subject of a thesis. His novels must be read carefully
Speed-related traffic accident analysis using GIS-based DBSCAN and NNH clustering
Full text linkTo ensure road safety and reduce traffic accidents, it is essential to determine geographical locations where traffic accidents occur the
most. Spatial clustering methods of hot spots are used very effectively to detect such risky areas and take precautions to minimize or
even avoid fatal or injury accidents. This study aims to determine speed-related hot spots in the pilot Mersin Region, which includes
seven cities in the central-southern part of Turkey. Two different hot spot clustering methods, the Nearest Neighbourhood
Hierarchical Clustering Method (NNH) and Density-Based Spatial Clustering of Applications with Noise (DBSCAN) Method, were
employed to analyse traffic accident data between 2014-2021, obtained from the General Directorate of Highways. CrimeStat III
program, which is free software, was used to detect NNH clusters, while the DBSCAN clusters were obtained using the open-source
GIS program QGIS, which was also used to visualize and evaluate the results comparatively. As a result of the analysis, it was
determined which method gave more effective results in determining the traffic accident risk clusters. These clusters were analysed
based on road geometries (intersection or corridors). In addition, by considering the areas where repeated accidents have occurred
over the years, future predictions of traffic accidents have been estimated
