The hybridization effect of sisal/cotton interwoven fabric backed by paper roving with jute woven material isinvestigated in the presence of polylactide (PLA) matrix. The biocomposites (five) were produced through varying different(100/0, 75/25, 50/50, 25/75, and 0/100) proportions of sisal/cotton with jute woven fabrics respectively in the laminates. Afterthe successful reinforcements, mechanical properties were investigated in terms of tensile and flexural tests. Moreover, thewater absorption, thickness swelling, and moisture content tests were also examined for assessing the physical anddimensional stability of developed hybrid composites. The water absorption and thickness swelling tests were carried out inthe presence of water after 2 h and 24 h immersion. The highest mechanical properties were found in case of 100 % sisal/cotton reinforced composites whereas the lowest value was observed in case of 100 % jute fiber. The morphological views ofthe developed materials were also characterized using SEM (Scanning electron microscopy) to observe the surfaces beforeand after the tensile load. The SEM deployed EDX (energy-dispersive X-ray) linear scanning was applied to explore thepresence of different chemicals in the biocomposite systems. The reinforcement effects of different fibers loading incomposite systems were also tested in terms of regression analysis and found that sisal/cotton interwoven fabrics existsignificant influence in the composite systems to increase the mechanical properties.

Enumeration of actor square of low order
M. Alp 장전수학회 2006 Proceedings of the Jangjeon mathematical society Vol.9 No.2
In this paper we describe a share package XMOD[2] of functions for computing with finite permutation crossed modules, cat1-groups and their morphisms, written using the GAP[5] group theory programming language. We also presented actor square of crossed modules which are Lue, Norrie, Whitehead, Actor crossed modules and include a table of source and range groups of crossed modules of actor square.

M. Alp 장전수학회 2006 Advanced Studies in Contemporary Mathematics Vol.13 No.2
In this paper we described a share package XMOD[2] of functions for computing with finite permutation crossed modules, cat-groups and their morphisms, written using the GAP [13] group theory programming language. We also presented actor square of crossed modules which are Lue, Norrie, Whitehead, Actor crossed modules. We gave a list of the simply connected and aspherical crossed modules of the direct products, sub-crossed modules and Factor crossed modules of the above crossed modules.

Coriander, Coriandrum sativum L., is an important medicinal plant belonging to the Apiaceae family, which is grown in many parts of Turkey. In this study, seven Turkish coriander varieties (Antakya, Arslan, Erbaa, Gurbuz, Kerkuk, Kudret-K, and Pelmus) were examined for phylogenetic relations using two ITS region (ITS4–ITS5) sequence information and their secondary structure analysis. The length of the nrDNA ITS sequences obtained in this study varied between 677 and 692 nucleotides for seven samples. The G+C content of the nrDNA ITS region ranged between 47.86 (ITS4) and 48.67% (ITS5). Secondary structural analysis revealed that variation between varieties is more unique. The AMOVA study confrmed the efectiveness of confguration analysis as variants accounted for the majority of the variance. In addition, variation within cultivars was signifcant (97%). This shows that a signifcant part of the variance detected in this study occurred among genotypes. Data analysis, including Shannon information index and scaled diversity overlap graph annotation, also showed that the highest level of heterozygosity occurred in the Arslan, Erbaa and Kudret-K genotypes, with cultivars showing more pronounced diferences genotypically rather than geographically, consistent with the expected heterozygosity (80%). By verifcation of the PCoA analysis, the genotypes of Gurbuz and Arslan are very diferent from those of other groups. This supports the results of the cluster analysis, which showed that the Ankara-origin Gurbuz variety had a very diferent genotypic diference. Our analysis recommends the use of ITS4 sequence and secondary structure data at the intraspecifc levels of coriander taxonomical classifcation. For the frst time, a study has used both sequence information and secondary structural information to describe coriander at the varietal level of taxonomic classifcation

The Role of Extra-Anatomic Bypass in the Surgical Treatment of Acute Abdominal Aortic Occlusion
Gokhan Ilhan,Şahin Bozok,Şaban Ergene,Sedat Ozan Karakisi,Nebiye Tufekci, M.D.,Hızır Kazdal,Sabri Ogullar,Seref Alp Kucuker 대한흉부외과학회 2015 Journal of Chest Surgery (J Chest Surg) Vol.48 No.3
Background: Aortic occlusion is rare catastophic pathology with high rates of mortality and severe morbidity. In this study, we aimed to share our experience in the management of aortic occlusion and to assess the outcomes of extra-anatomic bypass procedures. Methods: Eighteen patients who had undergone extra-anatomic bypass interventions in the cardiovascular surgery department of our tertiary care center between July 2009 and May 2013 were retrospectively evaluated. All patients were preoperatively assessed with angiograms (conventional, computed tomography, or magnetic resonance angiography) and Doppler ultrasonography. Operations consisted of bilateral femoral thromboembolectomy, axillo-bifemoral extra-anatomic bypass and femoropopliteal bypass and were performed on an emergency basis. Results: In all patients during early postoperative period successful revascularization outcomes were obtained; however, one of these operated patients died on the 10th postoperative due to multiorgan failure. The patients were followed up for a mean duration of 21.2±9.4 months (range, 6 to 36 months). Amputation was not warranted for any patient during postoperative follow-up.. Conclusion: To conclude, acute aortic occlusion is a rare but devastating event and is linked with substantial morbidity and mortality in spite of the recent advances in critical care and vascular surgery. Our results have shown that these hazardous outcomes may be minimized and better rates of graft patency may be achieved with extra-anatomic bypass techniques tailored according to the patient.
