Exponential Approximations On Multiplicative Calculus

Emine Misirli,Ali Ozyapici 장전수학회 2009 Proceedings of the Jangjeon mathematical society Vol.12 No.2

A new kind of calculus, multiplicative calculus, was developed and the de…nition of a new kind of derivative was given within this calculus. Multiplication and division, in this calculus, take the role of summation and di¤erence in the ordinary calculus. Thus, multiplicative calculus is based on multiplicative rate of change, whereas the ordinary calculus is based on additive rate of change. In this manner, many functions can be represented by infinite product, analogous to the infinite sum, based on multiplicative derivative. These generate an idea for getting exponential approximations to functions.

Emine, Kiyak Cellmed Orthocellular Medicine and Pharmaceutical 2017 TANG Vol.7 No.3

The purpose of this study was to analyze the effect wool in patients with chronic obstructive pulmonary disease. The study was conducted experimentally on 53 patients with chronic obstructive pulmonary disease attending the chest diseases polyclinic of a hospital located in Erzurum. A randomized selection method was used to categorize patients into two groups; a treatment (n = 27), and a control group (n = 26). Patients in the treatment group (pre-test measurements were taken) wore wool vests for a period of three months, while patients in the control group wore cotton vests (placebo) for the same duration; post-test measurements were taken for both groups at the end of the three-month period. The Medical Outcomes Study Short Form 36, the St. George's Respiratory Questionnaire, and pulmonary function tests were used to collect data. Results concluded that there was a significant decrease (p < 0.05) in the overall score of the St. George's Respiratory Questionnaire, and the symptom, effect, and activity mean scores, while there was a significant increase (p < 0.05) in the SF-36 physical functioning, general health, bodily pain, role physical, vitality, role emotional, social functioning, mental health, physical and mental component summary mean scores of patients in the treatment group. Results of the study concluded that the symptoms, activity, disease effectiveness, and quality of life improved in patients that wore wool vests.

A Simple Enzymatic Method for Quantitation of 2’-Fucosyllactose

( Emine Seydametova ),( Jonghyeok Shin ),( Jiwon Yu ),( Dae-hyuk Kweon ) 한국미생물생명공학회(구 한국산업미생물학회) 2018 Journal of microbiology and biotechnology Vol.28 No.7

2’-Fucosyllactose (2’-FL) is one of the most important human milk oligosaccharides and has several health benefits for infants. The levels of 2’-FL in breast milk or samples from other sources can be quantified by high-performance liquid chromatography. However, this method cannot be used for simultaneous detection of the target compound in numerous samples. Here, we developed a simple method for quantifying 2’-FL in a microplate format. The method involves two steps: (i) release of L-fucose from 2’-FL by α-(1-2,3,4,6)-L-fucosidase and (ii) measurement of NADPH formed during the oxidation of L-fucose by L-fucose dehydrogenase. This method enables measurement of up to 5 g/l 2’-FL in 50 min using a 96- well microplate. The efficiency and simplicity of the proposed method make it suitable for the analyses of a large number of samples simultaneously.

Most of the commercialized Bt crops express cry genes under 35S promoter that induces strong gene expression in all plant parts. However, targeted foreign gene expression in plants is esteemed more important as public may be likely to accept ‘less intrusive’ expression of transgene. We developed plant expression constructs harboring cry1Ac gene under control of wound-inducible promoter (AoPR1) to confine Bt gene expression in insect wounding parts of the plants in comparison with cry1Ac gene under the control of 35S promoter. The constructs were used to transform four Turkish cotton cultivars (GSN12, STN-468, Ozbek-100 and Ayhan-107) through Agrobacterium tumefaciens strains GV2260 containing binary vectors p35SAcBAR.101 and AoPR1AcBAR.101 harboring cry1Ac gene under control of 35S and AoPR1, respectively. Phosphinothricin (PPT) was used at concentration of 5 mg L-1 for selection of primary transformants. The primary transformants were analyzed for transgene presence and expression standard molecular techniques. The transformants exhibited appreciable mortality rates against larvae of Spodoptera exigua and S. littoralis. It was found that mechanical wounding of T1 transgenic plants was effective in inducing expression of cry1Ac protein as accumulated levels of cry1Ac protein increased during post-wounding period. We conclude that use of woundinducible promoter to drive insecticidal gene(s) can be regarded as a valuable insect-resistant management strategy since the promoter activity is limited to insect biting sites of plant. There is no Bt toxin accumulation in unwounded plant organs, seed and crop residues, cotton products and by-products, thus minimizing food and environmental concerns.

Example of iterative process in upcycled clothing design: Unused neckties and upholstery scraps

Emine Koca,Fatma Koç 복식문화학회 2020 服飾文化硏究 Vol.28 No.6

This study proposed a base framework for creating sustainable designs with textile production waste and unused neckties with the “design thinking” approach, which is an iterative process. It aimed to set an example of how fashion designers can plan and manage their clothing design processes in a more sustainable way by recycling textile production scraps and unused neckties into unique clothing pieces with the upcycling method. Unused neckties and upholstery scraps were turned into skirts, blouses, and dresses by using creative techniques in line with current fashion trends. In addition, the five-stage iterative design process followed was explained, and the way in which the waste textile materials gained value by being converted into unique garments was discussed in terms of the user and the designer. Through the study, it was observed that the smallest amount of textile waste can be transformed into upcycled clothing via the iterative process, and original, value-added products enjoyed by consumers can be created. In addition, it was observed that the design thinking approach improves the understanding of the context of the problem, creativity in the generation of insights and solutions, skills to materialize those solutions through iterative prototyping, and the ability to combine these factors. Promising ideas to help designers develop recycling strategies were also provided.

Cooking Quality and Sensorial Properties of Noodle Supplemented with Oat Flour

Emine Aydin,Duygu Gocmen 한국식품과학회 2011 Food Science and Biotechnology Vol.20 No.2

Effects of oat flour addition (10, 20, 30, and 40%) on the quality characteristics of noodle were investigated. Noodles were evaluated in terms of cooking quality, color, chemical, and sensory properties. As oat flour level increased, protein, crude fat, ash, Mn, Fe, Zn,and Mg contents of noodles increased. Oat flour caused increases in cooking loss of noodles. Sensory and cooking characteristics of noodles were negatively effected when oat flour level was increased compared with the control. Noodle with 10% oat flour received the highest sensory scores in all noodle samples containing oat flour. Overall acceptability scores of control and in only the noodle with 10% oat flour were found statistically (p<0.05) similar. Especially, the usage of 10% oat flour in noodle formulation gave satisfactory results in terms of acceptability.

Can Wideband Tympanometry Be Used as a Screening Test for Superior Semicircular Canal Dehiscence?

Emine Demir,Nazife Nur Afacan,Metin Celiker,Fatma Beyazal Celiker,Mehmet Fatih İnecikli,Suat Terzi,Engin Dursun 대한이비인후과학회 2019 Clinical and Experimental Otorhinolaryngology Vol.12 No.3

Objectives. We explored whether wideband tympanometry (WBT) could be used as a screening test for superior semicircular canal dehiscence (SSCD), and obtained new WBT data (given that the test is not yet in common clinical use) on patients with SSCD. Methods. We compared the WBT data of patients clinically and radiologically diagnosed with SSCD in our hospital between 2013 and 2018 to those of healthy volunteers. We compared the resonance frequency (RF), maximum absorbance frequency (MAF), and maximum absorbance ratio (MAR). The t-test was used for statistical analysis with the significance level set to P<0.05. In addition, we used receiver operating characteristic analysis to derive cutoff values for SSCD diagnosis in terms of sensitivity and specificity. Results. Seventeen patients (four with bilateral and 13 with unilateral disease; 17 ears) diagnosed with SSCD and 27 healthy volunteers (47 ears) were included. The mean RFs of the SSCD patients and healthy subjects were 548.7 Hz (range, 243 to 853 Hz) and 935.1 Hz (range, 239 to 1,875 Hz), respectively (P<0.001). The mean MARs of the SSCD patients and healthy subjects were 89.4% (range, 62% to 100%) and 82.4% (range, 63% to 99%), respectively (P=0.005). The mean MAFs of the SSCD patients and healthy subjects were 1,706.3 Hz (range, 613 to 3,816 Hz) and 2,668 Hz (range, 876 to 4,387 Hz), respectively (P<0.001). In terms of SSCD diagnosis, a MAR above 86% afforded 81% sensitivity and 77% specificity; an RF below 728 Hz, 86% sensitivity and 81% specificity; and an MAF below 1,835 Hz, 79% sensitivity and 67% specificity. Conclusion. WBT may be a useful clinical screening test for SSCD. The RF and MAF were lower, and the MAR higher, in SSCD patients than in normal controls.

Emine Esra Karaca,Feyza Dicle Işık,Özlem Evren Kemer 대한이식학회 2023 Korean Journal of Transplantation Vol.37 No.3

Background: Descemet membrane endothelial keratoplasty (DMEK) is increasingly favored in the treatment of endothelial dysfunction due to its benefits, which include swift visual rehabilitation and recovery, a relatively low rejection rate, and superior refractive stability. In this study, we examined alterations in corneal clarity among patients who underwent DMEK and correlated these densitometry findings with other optical parameters of corneal topography. Methods: The study incorporated 35 eyes from 35 patients who had previously undergone DMEK surgery for pseudophakic bullous keratopathy at Ankara Bilkent City Hospital. The results from these patients were compared with those from a healthy control group. The preoperative and postoperative optical parameters of the patients were assessed using Pentacam Scheimpflug topography (Oculus). Results: We observed significant decreases in corneal densitometry in the 0–2 mm and 2–6 mm zones of the anterior, posterior, central, and total layers at the sixth month postoperatively compared to the preoperative period (P<0.05). The corneal densitometry values at postoperative month 6 were elevated in all layers and zones relative to the healthy group (P<0.05). The root mean square of higher-order aberrations in postoperative period was elevated significantly (P<0.001). Conclusions: Six months after operation, the optical quality of the cornea following DMEK surgery did not achieve the level of a healthy cornea.

Artıstıc studies on desıgn development wıth fabrıc scrapsın the context of sustaınable fashıon

Emine KOCA 복식문화학회 2019 服飾文化硏究 Vol.27 No.6

The process of clothing production creates waste and scrap, which creates environmental, economic, and ethical issues. With this in mind the concept of ethical and sustainable fashion is discussed on many platforms as an important and timely topic. Many solutions have been presented on this subject. For the solution of this problem which has been increasing in the fashion and textile industry, the usage of sustainable materials and production methods is needed. There in a ‘recyclable material cycle’ should be adapted, instead of a ‘traditional material cycle’. New methods and techniques should be developed with multi-disciplinary design approaches to produce creative and high value-added products in the name of fashion and sustainability. This is seen as one of the more effective solutions. This study aims to show that production scraps can be transformed into timely clothing designs with samples. The fabric scraps from different brands were turned into unique clothing designs with up to date trends by designer. In the practices completed while following the design process, collage and patchwork techniques were applied depending on the characteristics of the scrap fabric, artistic figures were hand-stitched onto the design. With this study, the scraps that get thrown into dumping grounds and damage the ecosystem can turn into ethical and economic benefits for the manufacturer. How to choose new high value-added products and create an awareness of social responsibility is also shown with examples in this study.
