Effects of the addition of ulexite to the sintering behavior of a ceramic body

Salih Ugur Bayca 한양대학교 세라믹연구소 2009 Journal of Ceramic Processing Research Vol.10 No.2

The aim of this study was to investigate the effects of the addition of ulexite to the sintering behavior of a ceramic body. Ulexite is a boron mineral that is known as sodium calcium borate. The effects of ulexite, as a powerful flux, on the properties such as the water absorption, bending strength, and shrinkage and on the colors of ceramic tiles were studied. The microstructures of a standard and tiles with the additive were analyzed using a scanning electron microscope (SEM). The properties of with ulexite added tiles were compared with that of standard tiles and it was concluded that tiles having the additive had more favorable physical properties than the standard ones. Adding ulexite decreased the sintering temperature of the tiles, which in turn led to an increase in the bending strength of the tiles, a decrease in water absorption, and an increase in shrinkage. The SEM analyses have shown that ulexite additions increased the vitrification in the body.

Salih, Sarmad Ali,Kim, Hyeung-Rak The Korean Society of Fisheries and Aquatic Scienc 2014 Fisheries and Aquatic Sciences Vol.17 No.1

Marine brown algae have been identified as a rich source of structurally diverse bioactive compounds. Whether Myagropsis yendoi ethanolic extracts (MYE) inhibit inflammatory responses was investigated using lipopolysaccharide (LPS)-stimulated microglia BV-2 cells. MYE inhibited LPS-induced nitric oxide (NO) production in a dose-dependent manner and suppressed the expression of inducible nitric oxide synthase in BV-2 cells. MYE also reduced the production of pro-inflammatory cytokines in LPS-stimulated BV-2 cells. LPS-induced nuclear factor-${\kappa}B$ (NF-${\kappa}B$) transcriptional activity and NF-${\kappa}B$ translocation into the nucleus were significantly inhibited by MYE treatment through preventing degradation of the inhibitor ${\kappa}B-{\alpha}$. Moreover, MYE inhibited the phosphorylation of AKT, ERK, JNK, and p38 mitogen-activated protein kinase in LPS-stimulated BV-2 cells. These results indicate that MYE is a potential source of therapeutic or functional agents for neuroinflammatory diseases.

Presentation of Progressive Familial Intrahepatic Cholestasis Type 3 Mimicking Wilson Disease: Molecular Genetic Diagnosis and Response to Treatment

Salih Boga,Dhanpat Jain,Michael L. Schilsky 대한소아소화기영양학회 2015 Pediatric gastroenterology, hepatology & nutrition Vol.18 No.3

Progressive familial intrahepatic cholestasis type 3 (PFIC3) is an autosomal recessive disorder of cholestasis of hepatocellular origin, typically seen in infancy or childhood caused by a defect in the ABCB4 located on chromosome 7. Here we report on an older patient, aged 15, who presented with biochemical testing that led to an initial consid-eration of a diagnosis of Wilson disease (WD) resulting in a delayed diagnosis of PFIC3. Diagnosis of PFIC3 was later confirmed by molecular studies that identified novel mutations in the ABCB4 gene. Cholestasis due to PFIC3 can cause elevated hepatic copper and increased urine copper excretion that overlap with current diagnostic criteria for WD. Molecular diagnostics are very useful for establishing the diagnosis of PFIC3. Ursodeoxycholic acid amelio-rates cholestasis in PFIC3, and may help mediate a reduction in hepatic copper content in response to treatment.

Intelligent Network Data Analytics Function in 5G Cellular Networks using Machine Learning

Salih Sevgican,Meriç Turan,Kerim Gökarslan,H. Birkan Yilmaz,Tuna Tugcu 한국통신학회 2020 Journal of communications and networks Vol.22 No.3

5G cellular networks come with many new features compared to the legacy cellular networks, such as network data analytics function (NWDAF), which enables the network operatorsto either implement their own machine learning (ML) based dataanalytics methodologies or integrate third-party solutions to theirnetworks. In this paper, the structure and the protocols of NWDAFthat are defined in the 3rd Generation Partnership Project (3GPP)standard documents are first described. Then, cell-based syntheticdata set for 5G networks based on the fields defined by the 3GPPspecifications is generated. Further, some anomalies are added tothis data set (e.g., suddenly increasing traffic in a particular cell),and then these anomalies within each cell, subscriber category,and user equipment are classified. Afterward, three ML models,namely, linear regression, long-short term memory, and recursiveneural networks are implemented to study behaviour informationestimation (e.g., anomalies in the network traffic) and network loadprediction capabilities of NWDAF. For the prediction of networkload, three different models are used to minimize the mean absoluteerror, which is calculated by subtracting the actual generated datafrom the model prediction value. For the classification of anomalies, two ML models are used to increase the area under the receiver operating characteristics curve, namely, logistic regressionand extreme gradient boosting. According to the simulation results, neural network algorithms outperform linear regression innetwork load prediction, whereas the tree-based gradient boosting algorithm outperforms logistic regression in anomaly detection. These estimations are expected to increase the performance of the5G network through NWDAF.

“ASYA’SIZ ANADOLU, ANADOLU’SUZ ASYA OLMAZ!”

Salih Efilo?lu(살리흐 에필오울루) 국제언어문학회 2017 國際言語文學 Vol.- No.36

Ahmet Yesevî tried to cultivate the trained monks and disciples to Anadolu and all the lands that the Ottoman empire governed. On the base of his philosophical thinking, there is the love of human beings. Ahmet Yesevî is a rationalist and also mystic. Ahmet Yesevî insisted, “our duty is to practice the holy point of view and the thinking of civiliation. The approprite place for this is Anadolu. Anadolu is the best place to inform the world of human society. It is the place that culture and civilization meet each other. It welcomes all of you. There is no Asia without Anadolu. There is no Anadolu withoutAsia. Go to Anadolu, emit and receive energy” The love and mysterious adventure was begun like this. They made people living in diverse areas meet their values and mystic. Ahmet Yesevî ‘s messages about the method to reach at the peaceful society are enough to be a medicine to pain of humankind. UNESCO designated 2016~2017 as the Ahmet Yesevî ‘s year to celebrate his 850th anniversary.

Salih, Alaaddin M,Alfaki, Musab M,Alam-Elhuda, Dafallah M,Nouradyem, Momin M Asian Pacific Journal of Cancer Prevention 2016 Asian Pacific journal of cancer prevention Vol.17 No.4

Purpose: A multicenter, observational, cross-sectional study was conducted to assess factors delaying presentation of breast cancer cases. Materials and Methods: Data were collected from a pair of highly specialized referral centers, both located in the center of the Sudanese capital, Khartoum. For a total of 153 eligible respondents, durations of delay, clinicodemographic factors and reasons of referral were collected from our respondents through self-administered questionnaires. Logistic regression analysis and ANOVA were used to test the relation between periods of delay and different factors. Odd ratios (OR's) and their correspondent Confidence intervals (95% CI's). Delay periods were studied with Andersen's model. Results: The average duration of delay in our study was 11.9 (${\pm}11.2$) months. Only a quarter of our patients presented early within the first 3 months after onset of their symptoms. About 47.7% arrived later during the course of the first year, while it took beyond that for the last 27% to come. A prior diagnosis of BC was the only predictor of early presentation (for 3-12 months OR=9.6 (p<0.00), 95% CI 9.55-9.75; for >12 months OR=9.3 (p<0.00), 95% CI 9.33-9.33). Out of the 12 different reasons for delay given by our respondents, none showed a significant difference between patients presenting early or late. Financial incapacity (17.5%), ignorance about BC (14.3), and misinterpreting symptoms (12.7%) were the top three whys of delay. Conclusions: Our findings support existence of a non-uniform pattern of delay among Sudanese BC patients. Changing currently adopted awareness elevating strategies into much more inclusive approaches is strongly recommended.

Salih Çölmekçi,Ali Karpuz,Hakan Köçkar 한국화학공학회 2022 Korean Journal of Chemical Engineering Vol.39 No.7

Nickel-containing magnetic films have become the focus of attention due to their outstanding properties. These films are produced by many methods, including the sputtering technique. In this study, structural and magneticproperties of Ni/Cu multilayer films with different (from 92.5 nm to 17.5 nm) thicknesses of the Ni layers were investigated. The magnetron sputtering process was used to produce the Ni/Cu multilayer films. X-ray diffraction analysisshowed that the films have a face-centered cubic structure with (111) plane. According to the scanning electron microscopeimages, while the films with the Ni layers thicknesses of 92.5 nm and 42.5 nm have some cracks and row structureson their surfaces, the films with lower thicknesses of the Ni layers have relatively more regular surfaces. As the Nilayers thickness decreased, the saturation magnetization (Ms) decreased from 617 emu/cm3 to 387 emu/cm3. Althoughthe Ni/Cu multilayer with the Ni layer thickness of 92.5 nm had the highest atomic Ni content (76%); its coercivity (Hc)value was also the highest with 144 Oe. There was a decrease in the Hc value and grain size with decreasing the Nilayer thickness and the change in the Hc value can be related to the film content and surface morphology. The remanentmagnetization (Mr) value changed between 492 emu/cm3 and 105 emu/cm3 with the reducing the Ni layers thickness. The highest Mr value and the highest Mr/Ms ratio were obtained for the Ni/Cu film with the Ni layers thickness of42.5 nm. This Ni/Cu film has also the highest magnetization energy. The detected magnetic properties make this filmdesirable for permanent magnet and magnetic recording applications among the investigated Ni/Cu multilayers.
