Effects of the carbon nanotube and polymer amounts on ultrafiltration membranes

Evrim Celik Madenli,Zeliha Ilkay Ciftci 대한환경공학회 2022 Environmental Engineering Research Vol.27 No.4

Composite membranes with nano-sized inorganic materials have high selectivity, high hydrophilicity, and improved fouling resistance. Blending Carbon Nanotubes (CNTs) in the polymer solution improves membrane properties like hydrophilicity, water permeability, selectivity, and fouling resistance. The effect of the polymer amount, together with the CNT amount in the polymer solution on membrane properties, was investigated in this work. There was more than 10% increase in the hydrophilicity of the membranes with 1% CNT addition, but it was not altered with the polymer amount. The porosity was increased almost 30% by 1% CNT addition in membranes prepared by 10% and 12% polymer concentration (P-10:C-0 and P-12:C-0), but only 16% increase in porosity occurred in membrane prepared by 15% polymer concentration (P-15:C-0). The flux of the P-15:C-0 membrane was increased four times by 1% CNT addition. Besides, fouling resistance of the membranes decreased with increasing polymer amount but increased with increasing CNT amount. BSA rejection increased with increasing polymer amount or CNT amount in the polymer solution. Hence membranes prepared with a higher amount of polymer are more prone to membrane property improvements with CNT addition. The increase in flux and selectivity by CNT addition in all membranes prepared with different polymer concentrations will increase the membrane life-time and reduce the treatment cost.

Eco-Justice Mission and the Unity of the Church

Kinurung Maleh Maden 장로회신학대학교 세계선교연구원 2013 선교와 신학 Vol.32 No.-

This study discusses the WCC (World Council of Churches) commitment on eco-justice mission. The significance of this study is to re-echo all churches and Christians the fact that justice and love to all creation is already at the heart of Mission. The WCC, based on biblical theological consideration, confesses that eco-justice mission is Triune God’s mission. Thus, the WCC has persistently called the churches in unity to promote and exercise the eco-justice mission to and with all creation. To achieve this purpose, the writer revisit and reflect on various commitments of WCC from the official conciliar statements, assembly reports, conference meetings, website accounts, and others. Four areas need to be revisited in order to get wide-ranging reflection of WCC commitments on eco-justice mission: the historical review, cultural context of changing ecological landscape, theological consideration on Triune God, and eco-mission in practice. Historically, the organized and global commitment of WCC on mission to all creation has been for more than two decades. Theologically, the biblical foundation has been intensively constructed. Missionally, the global and various enterprises have been well programmed. So the vision and mission for the justice of the earth is not something new. However, the question is: why is the eco-injustice persistently haunting us? The poverty and oppression are still present directly related to the unjust natural resource distribution, economic international system, and consumerist lifestyle. In fact, within 20 years the changing ‘earth’ landscape is worse; the climate change has affected suffering both to billion of human and non-human. This situation asks the WCC and her members again and again of his missional role as the agent and instrument of God’s mission. By revisiting and reflecting the WCC commitment on eco-mission, this paper is significant to maintain the unity of all churches in promoting and exercising consistently the eco-justice to all creation.

Imdat Iscan,Tekin Toplu,Selahattin Maden 호남수학회 2022 호남수학학술지 Vol.44 No.3

The aim of this study is to establish some new Jensen and Lazhar type inequalities for p-convex function that is a generalization of convex and harmonic convex functions. The results obtained here are reduced to the results obtained earlier in the literature for convex andharmonic convex functions in special cases.

On a novel eccentricity-based invariant of a graph

Xu, K. X.,Das, K. C.,Maden, A. D. Springer Business + Business Media 2016 Acta mathematica Sinica. English series Vol.32 No.12

<P>In this paper, for the purpose of measuring the non-self-centrality extent of non-selfcentered graphs, a novel eccentricity-based invariant, named as non-self-centrality number (NSC number for short), of a graph G is defined as follows: N(G) = Sigma(vi), (vj is an element of V(G)) vertical bar e(i) - e(j)vertical bar where the summation goes over all the unordered pairs of vertices in G and e(i) is the eccentricity of vertex vi in G, whereas the invariant will be called third Zagreb eccentricity index if the summation only goes over the adjacent vertex pairs of graph G. In this paper, we determine the lower and upper bounds on N(G) and characterize the corresponding graphs at which the lower and upper bounds are attained. Finally we propose some attractive research topics for this new invariant of graphs.</P>

Detection of Pathotypes and Genetic Diversity of Cercospora beticola

Turgay, Emine Burcu,Bakir, Melike,Ozeren, Pinar,Katircioglu, Yakup Zekai,Maden, Salih The Korean Society of Plant Pathology 2010 Plant Pathology Journal Vol.26 No.4

The pathotypes of Cercospora beticola, causal agent of sugar beet leaf spot disease, were identified by application of pathogenicity test using 100 isolates obtained from the provinces with intensive sugar beet cultivation. For the identification of pathotypes, five sugar beet cultivars were used each with different resistance factors. Cultivar reactions were determined by inoculation of cultivars with the isolates under controlled conditions and measuring disease severity on the $15^{th}$ day according to the 1-9 KWS Scale. Based on the reactions of the five cultivars, a total of 15 pathotypes were detected. All employed sugar beet cultivars were resistant to Pathotype no:1 comprising most of the isolates. Genetic diversity of the causal agent was characterized by AFLP reaction. The products acquired at the end of AFLP reaction were detected by means of Beckman CEQ 8800 DNA Capillary Series Analysis and the results obtained were evaluated according to the similarity index UPGMA. For the genetic analysis of C. beticola isolates, 9874 polymorphic fragments of sizes between 100 and 500 bp were analysed which were generated by nine primers. The dendrogram derived from AFLP analysis depicted the existence of five different subgroups. The polymorphism rate among isolates was 91.13% and the dendrogram distribution of the pathotypes obtained by pathogenicity indicated that pathotypes were not discriminated and did not compose any groups.

The Association between Whole Blood Viscosity and Coronary Collateral Circulation in Patients with Chronic Total Occlusion

Background and Objectives: Coronary collateral circulation (CCC) has been attributed as inborn bypass mechanisms supporting ischemic myocardium. Various factors have been postulated in CCC. Whole blood viscosity (WBV) has been an underappreciated entity despite close relationships between multiple cardiovascular diseases. WBV can be calculated with a validated equation from hematocrit and total plasma protein levels for a low and high shear rate. On the grounds, we aimed to evaluate the association between WBV and CCC in patients with chronic total occlusion. Subjects and Methods: A total of 371 patients diagnosed as having at least one major, chronic total occluded coronary artery were included. 197 patients with good CCC (Rentrop 2 and 3) composed the patient group. The poor collateral group consisted of 174 patients (Rentrop grade 0 and 1). Results: Patients with poor CCC had higher WBV values for a low-shear rate (LSR) (69.5±8.7 vs. 60.1±9.8, p<0.001) and high-shear rate (HSR) (17.0±2.0 vs. 16.4±1.8, p<0.001) than the good collateral group. Correlation analysis demonstrated a significant negative correlation between the grade of CCC and WBV for LSR (β=0.597, p<0.001) and HSR (β=0.494, p<0.001). WBV for LSR (β=0.476, p<0.001) and HSR (β=0.407, p<0.001) had a significant correlation with the synergy between percutaneous coronary intervention with taxus and cardiac surgery (SYNTAX) score. A multivariate analysis showed that the WBV for both shear rates were independent risk factors of poor CCC (WBV at LSR, OR: 1.362 CI 95%: 1.095-1.741 p<0.001 and WBV at HSR, 1.251 CI 95%: 1.180-1.347 p<0.001). Conclusion: WBV has been demonstrated as the overlooked predictor of poor coronary collateralization. WBV seemed to be associated with microvascular perfusion and angiogenesis process impairing CCC development
