Effect of Waste Marble Powder and Fly Ash on the Rheological Characteristics of Cement Based Grout

This paper shows the results of an experimental study conducted to research the impact of waste marble powder (WMP) and fly ash (FA) on the fluidity (marsh cone flow time (MCFT), mini-slump diameter and plate cohesion meter (PCM)) and the rheological properties (viscosity and yield stress) of cement based grout (CBG) mixtures. The experiments were applied with the CBG mix including 1.00 water-binder (w/b) ratios and combined use of WMP (5-25%), FA (5-25%) and WMP+FA (10-30% + constant 25%). Test results illustrated that the rheological properties of the CBGs importantly have been improved by the addition of WMP, FA and WMP+FA to grout mix at w/b=1 ratio. Strongly shear thickening behaviour was got from the CBG mixtures the all WMP, FA and WMP+FA content. The increase in the percentage of WMP (5-25%) amount reduced the mini-slump flow diameter. Moreover, the increment in the percentage of FA (5-25%) amount increments the mini slum flow. According to the control sample, the increment in the percentage of WMP (10-25%) amount increased the mini-slump flow diameter for constant FA (25%) content. Also, the increase in WMP amount in the CBG mix, there is no effect on MCFT. Also, MCFT decreased with the increase of FA amount. Especially, FA increased the fluidity of CBG, when the WMP showed negative effect in increase the MCFT in WMP+FA content

Chemical synthesis of LSGM powders for solid oxide fuel cell (SOFC) electrolyte

Synthesis of LSGM (La0.9Sr0.1Ga0.8Mg0.2O3-delta), LSFM (La0.9Sr0.1Fe0.8Mg0.2O3-delta), and LSCM (La0.9Sr0.1Cr0.8Mg0.2O3-delta) powders were achieved via organic precursor method. Different organic "carrier" molecules were used for powder synthesis. Citric acid, tartaric acid, Pechini precursors, polyvinyl alcohol, and ethylene diaminetetraacetic acid were selected as organic carriers for their ability to stabilize the metal ions. Each organic carrier material exhibited a different degree of effectiveness in the synthesis of the mixed oxide powders. One of the main factors affecting the phase purity appears to be the interaction of the functional groups with the constituent cations. The effectiveness of the organic carrier with varying number and type of functional groups is evaluated and discussed in terms of the phase distribution in the powders after the calcination step

Comparative genomic characterization of indigenous fat-tailed Akkaraman sheep with local and transboundary sheep breeds

The domestic sheep with over 1200 breeds descended from those early domesticated animals that are bred for a variety of resources such as meat, milk and wool. Akkaraman, a fat-tailed indigenous sheep breed of Turkiye, is widespread throughout Central Anatolia, with the largest indigenous sheep population. Assessing the genetic diversity and genomic structure of animal breeds is among the key contributors to deciphering adaptation to environmental extremes and constructing efficient genetic improvement strategies. Therefore, this study aimed to characterize the genome of Akkaraman breed against various world-renowned transboundary sheep and indigenous sheep with fat and thin tails. Genetic similarities and differences between those breeds have been displayed by estimating and comparing various genetic diversity indices, linkage disequilibrium (LD) estimates and fixation index (FST), runs of homozygosity (ROH) as well as PCA and neighbour-joining tree analysis. Akkaraman sheep were observed to form a cluster alongside Moghani, Karakas, Tibetan and Cyprus Fat Tail sheep, which are primarily the sole representatives of fat-tailed sheep in the study. This clustering was evident in both the PCA and neighbour-joining tree analysis. The Akkaraman sheep was also observed to have the lowest genomic inbreeding and one of the lowest numbers of ROHs, which might also indicate that the breed has not been exposed to historical intensive selection pressure, inbred mating or a massive population bottleneck that might leave strong marks of genomic homozygosity. The results improve our understanding of the genetic diversity in Akkaraman sheep in comparison with certain mainstream sheep breeds as well as those indigenous breeds from around the world. Additionally, findings will also provide valuable insights to perform further GWAS effectively by considering population structure, diversity and LD patterns observed among the breeds while providing practical knowledge that will contribute to designing efficient and successful genome-based selection programmes for worldwide sheep production systems

Temporary Foldable Children's Socialization Spaces After Earthquake: Interior Architecture Workshop Experience

Earthquakes are among the natural disasters that leave behind severe psychological, sociological, and economic damage. The significant earthquakes that struck our nation on February 6, 2023, with their epicenter at Kahramanmaraş, resulted in numerous fatalities and destruction of property. All kinds of entrepreneurs are essential to the post-disaster recovery process because they offer creative fixes and advancements. Within the framework of the Interior Architecture Project-IV course, an online workshop on "Temporary Foldable Children's Socialization Spaces After the Earthquake" was conducted with students from Selçuk University Faculty of Architecture and Design, Department of Interior Architecture. A three-stage systematic approach for design-oriented learning is employed, comprising stages for implementation, creative decision-making, and analytical comprehension. The outcomes of the workshop show that students studying interior architecture are capable of coming up with original solutions to design issues. Foldability has been highlighted as a key idea that influences form choices in function solutions and has given students the capacity to design at various scales, ranging from space design to equipment design

Effects of two different acid etching and surface washing methods on bond strength on different CAD-CAM blocks under aging protocols

Aim. The purpose of this study is to investigate the effects of hydrofluoric acid and one-component ceramic primer and silane (Monobond Etch and Prime (MEP)) applications on lithium disilicate glass ceramics and zirconium-infiltrated lithium silicate glass ceramics, as well as the effect of ultrasonic and phosphoric acid surface washing methods on bond strength. Materials and Method. A total of 240 ceramic samples were prepared using two different CAD-CAM material blocks with a thickness of 2 mm made of lithium disilicate glass-ceramic (IPS e.max CAD) and zirconium-infiltrated lithium silicate glass ceramic blocks (Celtra Duo). The samples were cemented to the composite discs (Tetric N-Ceram) after two different acid treatments, and surface washing processes were applied to them. As such, 24 groups were formed, each with two different acid applications, three different washing processes, two different CAD-CAM blocks, and two different aging procedures (n=10). Following the application of the acid, different washing processes are used. These were HF acid and washing only (HF + W), HF acid and ultrasonic washing (HF + US), HF acid and phosphoric acid (HF + PA), MEP with washing only (MEP + W), MEP and ultrasonic washing (MEP + US), and MEP and phosphoric acid (MEP + PA). The composite discs were cemented with dual cure adhesive cement (Multilink Automix) after the determined surface treatments were applied to the blocks. After surface applications, SEM analysis was conducted. Following exposure to two different thermal procedures, long-term (TL) and short-term (TS), bond strengths were measured using an Instron universal test device. SPSS version 23.0 software was used to perform the statistical analyses. Histogram graphs and the Kolmogorov-Smirnov/Shapiro-Wilk test were used to assess the variables' conformity to the normal distribution. Results. The bond strength values of TS and TL in the Celtra Duo block were significantly higher than those in the e.max CAD block (p<0.05). The TS-TL bonding strength value difference in the e.max CAD block was significantly higher than the surface measurements in the Celtra Duo block. While the highest bond strength value HF + US for TS in e.max CAD was 20.07±.31, the values of HF + US in Celtra Duo were significantly higher in terms of TL values when compared to other groups. Conclusion. Celtra Duo material demonstrated higher bond strength values after a short and long thermal cycle than e.max CAD material. In general, groups bonded with HF were less affected by the thermal cycle than groups treated with MEP

In-hospital and short-term predictors of mortality in patients with intermediate-high risk pulmonary embolism

Introduction: The aim of this study was to evaluate the in-hospital and short-term predictive factors of mortality in intermediate-high risk acute pulmonary embolism (PE) patients with right ventricle (RV) dysfunction and myocardial injury.Methods: In this retrospective study, the medical records of 187 patients with a diagnosis of intermediatehigh risk acute PE were evaluated. A contrast-enhanced multi-detector pulmonary angiography was used to confirm diagnosis in all cases. All-cause mortality was determined by obtaining both in-hospital and 30 days follow-up data of patients from medical records.Results: During the in-hospital stay (9.5 +/- 4.72 days), 7 patients died, resulting in an acute PE related in-hospital mortality of 3.2%. Admission heart rate (HR), (Odds ratio (OR), 1.028 95% Confidence interval (CI), 0.002-1.121; P = 0.048) and blood urea nitrogen (BUN) (OR, 1.028 95% CI, 0.002-1.016; P = 0.044) were found to be independent predictors for in-hospital mortality in a multivariate logistic regression analysis. In total, 32 patients (20.9%) died during 30 days follow-up.The presence of congestive heart failure (OR, 0.015, 95%CI, 0.001-0.211; P = 0.002) and dementia (OR, 0.029, 95%CI, 0.002-0.516; P = 0.016) as well as low albumin level (OR, 0.049 95%CI, 0.006-0.383; P = 0.049) were associated with 30 days mortality.Conclusion: HR and BUN were independent predictors of in-hospital mortality and the presence of congestive heart failure, dementia, and low albumin levels were associated with higher 30 days mortality

Comparison of Optical versus Ultrasonic Biometry in Keratoconic Eyes

Purpose. To compare the measurements of optical versus ultrasonic biometry devices in keratoconic eyes. Materials and Methods. Forty-two eyes of 42 keratoconus (KC) patients enrolled in the study were examined. Clinical and demographic characteristics of the patients were noted, and detailed ophthalmological examination was performed. Following Pentacam measurements, central corneal thickness (CCT), anterior chamber depth (ACD), lens thickness (LT), and axial length (AL) were obtained using the Lenstar and US biometer to determine the reproducibility of the measurements between the two devices in keratoconic eyes. The Bland-Altman method was used to describe the agreement between the two devices. Results. The Lenstar could not measure at least one of the biometric properties in one eye and did not automatically give the corrected ACD in 2/3 of our study population. The Lenstar measured CCT (average difference 5.4 ± 19.6 µm; ICC = 0.90; ), LT (average difference 0.13 ± 0.17 mm; ICC = 0.67; ), and AL (average difference 0.10 ± 0.76 mm; ICC = 0.75; ) thinner than US biometer, whereas it measured ACD (average difference 0.18 ± 0.17 mm; ICC = 0.85; ) deeper than US biometer in keratoconic eyes. Conclusion. Although the difference between the measurements obtained using the two devices might be clinically acceptable, US biometry and Lenstar should not be used interchangeably for biometric measurements in KC patients

Genome-Wide Scan of Wool Production Traits in Akkaraman Sheep

The objective of this study was to uncover the genetic background of wool quality, a production trait, by estimating genomic heritability and implementing GWAS in Akkaraman sheep. The wool characteristics measured included fibre diameter (FD) and staple length (SL) at the age of 8 months and yearling fibre diameter (YFD), yearling staple length (YSL) and yearling greasy fleece weight (YGFW) at 18 months of age. Animals were genotyped using the Axiom 50 K Ovine Genotyping Array. Maximum likelihood estimations of a linear mixed model (LMM) were used to estimate genomic heritability, where GWAS was conducted following a score test of each trait. Genomic heritability estimates for the traits ranged between 0.22 and 0.63, indicating that phenotypes have a moderate range of heritability. One genome- and six chromosome-wide significant SNPs were associated with the wool traits in Akkaraman lambs. Accordingly, TRIM2, MND1, TLR2, RNF175, CEP290, TMTC3, RERE, SLC45A1, SOX2, MORN1, SKI, FAAP20, PRKCZ, GABRD, CFAP74, CALML6 and TMEM52 genes as well as nine uncharacterized regions (LOC101118971, LOC105609137, LOC105603067, LOC101122892, LOC106991694, LOC106991467, LOC106991455, LOC105616534 and LOC105609719) were defined as plausible candidates. The findings of this study shed light on the genetics of wool quality and yield for the Akkaraman breed and suggests targets for breeders during systematic breeding programmes

The effects of different root canal irrigation protocols and artificial aging procedures on the bond strength between dentin and hybrid ceramic posts

The purpose of this study is to investigate the effects of different root canal irrigation protocols applied to the dentin and artificial aging procedures on the micro pushout bond strength (mPBS) between dentin and hybrid ceramic posts. Seventy-five single-rooted mandibular premolar teeth were divided into 5 groups (Gr1-5). 50 of the teeth were used for the mPBS tests (n = 10), whereas 25 were used for the smear layer examinations (n = 5). Post space were prepared and irrigated with different irrigation-protocols in each group. (Gr1:[SS], Gr2:[NaOCl] + SS, Gr3:[EDTA] + NaOCl + SS, Gr4:[MA] + NaOCl + SS, Gr5:[Ch] + NaOCl + SS). Post and core pattern were fabricated with pattern resin and a fiber post, after scanning, the posts were milled with Vita Enamic resin ceramic block, and cemented. After 7 days the roots were sliced at thicknesses of 1 mm; half of them were subjected to mPBS test, while the other half were tested after undergoing mechanical cycling for artificial aging. For data analysis, the Shapiro-Wilk test was utilized to test normal distributions, 3-way analysis of variance was used to compare mPBS, and Tukey’s HSD test was conducted for multiple comparisons. SEM analysis was performed for examination of failure modes and smear layer removal. Different root canal irrigation protocols affected mPBS significantly. While Gr4 had the highest mPBS, Gr1 had the lowest. Regarding to different zones, the highest mPBS was in coronal zone, and the lowest one was in the apical zone. The aging procedure also led to a statistically-significant decrease in mPBS. Most frequent failure modes were cohesive failure in dentin and mixed failure. Irrigation with 7%MA (Gr4) showed better performance than 17% EDTA (Gr3) in smear layer removal, especially at the apical zone of the tooth. This is critical for the success of root canal treatment and increased the mPBS to a higher extent in all zones of the tooth

Dialogue in Tahsin Germiyani's Novels –In the Example of al-Huznu'l-Vesim, Evladu'l-Yahudiyye, Zaknemut-

In the novels of Tahsin Germiyani, who stands out as a narrator and novelist, dialogue was a basic technique for artistic work. Because he used the art of dialogue in a unique way to carry out communication and understanding and to fictionalize events. Such that Tahsin Germiyani's novels are considered to fill a gap in this aspect, especially in Iraq and in the Arab world in general .What makes him important is the writers he read and was influenced by. Such that when we look at his works, this effect is noticeable. Rather than a reflection, this influence manifests itself in a new and different form with internalization. The new work now contains in itself his character, is far from alienation, and becomes compatible with the culture and values of the society in which he lives. It is possible to see this situation not only in dialogues, but also in the whole structure of the work. Tahsin Germiyani has written 7 novels. However, in this study, we will focus on his three novels (al-Huznu'l-vesim, Evladu'l-Yahudiyye and Zaknemut) to reveal how the dialogue is used as a technique. After giving basic information about the concept of dialogue and Tahsin Germiyani's life and works, we will try to reveal how he used dialogue in these three novels that we will take as a field of application and his artistic connections in the storylines. Germiyani used both forms of dialogues in different stages. In his novel Zaknemut, he performed the internal dialogue mostly in the forms of monologue, pleading and reaction. While the external dialogue is mostly includedin the novel al-Huznu'l-Vesim, he used both dialogues to convey his thoughts, to effectively present his reaction and his opinionson the social phenomena in Iraqi society. Because he wanted to bring to light the mistakes and deficiencies that he saw and experienced in the society. He did this with an artistic task, by describing situations that trigger interpersonal conflict, sometimes using the inner and external dialogues of the protagonists and sometimes of the deuteragonists. One of his prominent features during this fiction is hisability to make the dialogues more vivid and permanent in the mind of the reader by using the cinema technique and to make the reader a partner in this fiction. We also witness that he makes this ability more effective by using the folkspeech. We will try to put forward the relevant issues practically within the framework of his 3 novels
