Item Accuracy of ultrasonography in detecting fragmentation of the medial coronoid process in dogs(Amer Veterinary Medical Assoc, 2009-02-15) Michele, Ursula; Tacke, Sabine; Kramer, Martin; Gerwing, Martin; Seyrek, Deniz İntaş; Uludağ Üniversitesi/Veteriner Fakültesi/Doğum ve Jinekoloji Anabilim Dalı.; 6506990178Objective-To determine the accuracy of ultrasonography in detecting fragmentation of the medial coronoid process (FMCP) in dogs. Design-Cross-sectional study. Animals-102 dogs (112 elbow joints) suspected to have FMCP Procedures-Elbows were examined ultrasonographically prior to surgery for evidence of fragmentation, fissuring, or deformation of the medial coronoid process; thickening of the joint capsule; joint effusion; and secondary new bone formation. Results were compared with intraoperative findings. Results-At surgery, 51 (46%) joints had free fragments, 55 (49%) had nondisplaced fragments, and 6 (5%) did not have any fragments or fissures. Fragments were not seen ultrasonographically in 23 of the 51 (45%) joints in which a free fragment was found during surgery or in 50 of the 55 (91%) joints in which a nondisplaced fragment was found during surgery. Accuracy of using ultrasonographic evidence of any medial coronoid process abnormality (ie, a medial coronoid process fragment, deformation of the medial coronoid process, or both) for diagnosis of medial coronoid process fragmentation was 77%. The kappa coefficient for the level of agreement between ultrasonographic (ie, any medial coronoid process abnormality) and surgical findings was -0.014, indicating that there was no agreement. Conclusions and Clinical Relevance-Results suggested that ultrasonography was of limited diagnostic value in detecting FMCP in dogs.Item Acquisition of English ergative verbs by Turkish students: Yesterday and today(Elsevier, 2009) Uzunboylu, H.; Çavuş, N.; Can, Abdullah; Uludağ Üniversitesi/Eğitim Fakültesi/Yabancı Diller Eğitimi Bölümü.; 26656513300This study tries to diagnose the acquisition of a special subclass of intransitive verbs, namely ergatives, by Turkish learners of English by comparing the (partial) results of the study carried out in 2000 (as an MA Thesis) with the results of its replication conducted in 2007. In both studies all the variables were the same. Proficiency levels were determined via a cloze test and a grammaticality judgment test with various subclasses of intransitives was administered. Results of the study have revealed that proficiency levels of the participants have increased in seven years, but paired ergative verbs have remained the most problematic subclass of intransitives in both studies.Item Adjunctive use of the uterine artery resistance index in the preoperative prediction of myometrial invasion in endometrial carcinoma(Academic Press Inc Elsevier Science, 1999) Yalçın, Ömer T.; Özalp, Sinan; Develioğlu, Osman H.; Bilgin, Tufan; Ozan, Hakan; Uludağ Üniversitesi/Tıp Fakültesi/Kadın Hastalıkları ve Doğum Anabilim Dalı.Objective. The aim of this study was to evaluate the value of transvaginal ultrasonography (TVUS) and uterine artery flow velocimetry indices in the preoperative detection of deep myometrial invasion in endometrial carcinoma (EC). Methods. Thirty-nine patients with EC underwent TVUS and Doppler flow velocimetry studies, during which endometrial, myometrial, and uterine measurements, presence and depth of myometrial invasion, and pulsatility and resistance indices (PI and RI, respectively) of uterine arteries were noted. TVUS and Doppler findings were correlated with pathological findings obtained by surgical staging. The respective diagnostic accuracies of these variables, and of age and grade, in detecting deep myometrial invasion were assessed with the use of histological findings as the standard. Results. All patients with Grade 3 tumors had deep myometrial invasion, compared to 19% of patients with Grade 1 tumors. The mean age of patients with deep invasion was significantly higher, and their mean PI and RI were significantly lower, than patients with lesser degrees of invasion. While the sensitivity and specificity of TVUS in detecting deep invasion were 37 and 90%, respectively, the corresponding figures for age, grade, and uterine artery RI, found to be independent discriminators of deep invasion, were in the range of 58-84% and 60-70%. The combined use of the latter three parameters resulted in a sensitivity of 100% and specificity of 95%. Conclusions. Our findings indicate that TVUS is unreliable in diagnosing deep myometrial invasion. Detection rates of this pathological feature can be greatly improved, however, with the concomitant use of age, tumor grade, and uterine artery RI.Item An alternative assessment scale for student work produced in the architectural studio(Elsevier Science, 2010) Uzunboylu, H.; Taneli, Yavuz; Tok, Selay Yurtkuran; Uludağ Üniversitesi/Mimarlık Fakültesi/Mimarlık Bölümü.; 0000-0003-0349-1098; C-3035-2008; 36544397500; 36544333500This paper investigates the utility of a scale specifically designed to evaluate work produced in the architectural studio. The primary aim of the scale is to provide design critique to students, while fostering motivation. The data to be presented in this study were gathered during a studio class of the core curriculum from 20 undergraduate students of the Department of Architecture at Uludag University. Students were asked to compare two alternative evaluation processes, color-coding and smiley faces, both with verbal descriptions, to the conventional 100-point grading scale. The quality and effectiveness of the rating scales in assessing creative work was evaluated.Item Ambulatory activities in Turkish adults without exercise habits(Ortadoğu Yayınları, 2010-06) Arabacı, Ramiz; Uludağ Üniversitesi/Spor Bilimleri Fakültesi/Beden Eğitimi ve Spor Öğretmenliği Bölümü.; 0000-0001-8403-5742; ABI-4831-2020; 24448984800Objective: The purpose of this study was to examine ambulatory activities in healthy Turkish adults without exercise habits. Material and Methods: This study was conducted in 2006-2007 education year in Bursa/Turkey. Ambulatory activity in participants between 18-85 years (women, n= 1000; men, n= 915) assessed by daily pedometer steps. The relations of parameters, such as their age, body mass index (BMI), education, annual income, marital status, number of children, smoking and alcohol consumption were determined with number of daily steps. Results: Median (interqr. range) steps/day in women and men respectively were 7854 (5366) and 8760 (5596) steps/day (p= 0.000). In both women and men, there was significantly negative relation between daily step number and age (women r= -.268, p= 0.000; men r= -.126, p=0.000), and BMI (women r= -.148, p= 0.000; men r= -.074, p= 0.044) values; there was a significantly positive relation between daily step number and annual income. Conclusion: Ambulatory activities of Turkish women are less than men. The finding of this study revealed that in both genders, as the age and BMI increases, daily step numbers decrease, and as annual family income increases, daily step number increases as well. As the number of the children increases, occurs a decrease in the daily step numbers, especially of the women.Item Analysis of genetic diversity of local olive varieties in Turkey by AFLP markers(Int Soc Horticultural Science, 2011-12-31) Hummer, K. E.; Şeker, Murat; Gündoğdu, Ayşe; İpek, Meryem S.; Uludağ Üniversitesi/Ziraat Fakültesi/Bahçe Bitkileri Bölümü.; 16031208900Olive (Olea europaea L.) has great genetic variation in Turkey as important crop due to its economic value. There are many cultivars, types and landraces having good potential as a source of genes for productivity, oil quality and fruit characters which are difficult to differentiate by using morphological characters in different ecological conditions of Turkey. Therefore, genotypic identification studies are important for olive breeding, olive industry and genome analysis. In this study, local olive genotypes which are grown in Adana, Artvin, Aydin, Balikesir, Bursa, Canakkale, Gaziantep, Hatay, Kilis, Izmir, Manisa, Mersin and Tekirdag provinces of Turkey were investigated. Most of the genotypes in this study were used for the first time for evaluation of their genetic structures. Genetic diversity of local genotypes was estimated using amplified fragment length polymorphism (AFLP) markers. Sixty three olive genotypes were analyzed with five EcoRI-MseI primer combinations. Informative AFLP markers were generated and scored as binary data. Five primer pairs used in AFLP analysis detected 173 loci, of which 135 (78%) were polymorphic. Similarity coefficient matrix was computed to cluster the data and to draw precise relationships among the 63 studied olive genotypes. The generated dendrogram revealed three major groups.Item The analysis of the factors affecting the acquisition and usage of the contemporary knowledge in the social studies education: Families(Elsevier, 2009) Uzunboylu, H.; Çavuş, N.; Doğan, Yadigar; Uludağ Üniversitesi/Eğitim Fakültesi/İlköğretim Bölümü/Sosyal Bilgiler Eğitimi Anabilim Dalı.; 26656529900The present study was conducted with the aim of analyzing the methods of and the factors affecting the acquisition of comtemporary knowledge in the social studies lessons in primary education programs according to the criteria required by the age of information.

Students were asked to draw a rectangle in the course of a mathematics lesson and a flower in that of science. The sample included 50 students from the primary education department at Uludag University, Bursa, Turkey. Their responses were analyzed using the same grid. Two main categories were distinguished: the drawing of a concept's structure (conceptual, iconic, redundant/missing drawing) and labeling/coding of the concept's parts (comprehensive, partial, incorrect labeling). The first finding shows that students who produced a response categorized as conceptual and iconic drawings were identified as in the comprehensive labeling category. Thus, there may be a relationship between conceptual and iconic drawings and conceptual comprehension. Another finding concerns the similarities in the categorization of responses for both maths and science questions. Students who made iconic and conceptual drawings were able to label more correctly than students who drew a redundant/missing drawing. In addition, it can also be said that for the biology drawing the whole flower was observed whereas in geometry an abstract subject which is not generally observed was made physical by the drawing.Item Antifungal activity of chestnut shell extracts(INT SOC Horticultural Science, 2010) Bounous, G.; Beccaro, G. L.; Kumral, Ayşegül Yıldırım; Yavuz, Mümine; Korukluoğlu, Mihriban; Ertürk, Ümran; Uludağ Üniversitesi/Ziraat Fakültesi/Gıda Mühendisliği Bölümü.; Uludağ Üniversitesi/Ziraat Fakültesi/Bahçe Bitkileri Bölümü.; AAG-8415-2021; J-5125-2018; 16039935800; 36814751100; 8213196200; 7801661220Shells of three different chestnut cultivars named as 'Marigoule', 'Maraval' and '52112' ('Vakit Kestanesi') were tested for their antifungal activities against Penicillium roqueforti, Aspergillus niger and Aspergillus parasiticus. Ethanol extracts were obtained by soxhlet extraction and antifungal activities were determined with three point inoculation method and an automated quantitative assay by absorbance measurement at 595 nm on a microplate reader. Results of the two methods demonstrated that ethanol extracts of 'Marigoule' and 'Maraval' retarded the growth of Aspergillus niger but did not inhibit it completely. None of the three extracts inhibited Penicillium roqueforti according to microplate assay; but on the contrary stimulatory effects of '52112' on the mentioned mould were determined. Contradictory results were obtained from two methods concerning the antifungal effect of three extracts, so further studies are needed for the factors causing variations between two methods and the composition of the chestnut shell extracts to determine the antifungal activity more accurately.Item Applicability of nanofiltration in the recovery of chrome tanning wastewater(Elsevier, 2012) Kiril, Berna Mert; Marsh, Nicola; Kestioǧlu, Kadir; Uludağ Üniversitesi/Fen Bilimleri Enstitüsü/Çevre Mühendisliği Bölümü.; 8910702800Item The application of disaster management in Turkey from a comparative perspective: A proposal for a new model(Wit Press, 2010) Gündüz, İbrahim Emre; Brebbia, C. A.; Parlak, Bekir; Uludağ Üniversitesi/İktisadi ve İdari Bilimler Fakültesi/Siyaset Bilimi ve Kamu Yönetimi Bölümü.; 0000-0002-9173-7563; AAG-7412-2021; 57222629138This study examines the mutual relations between risk, risk society and types of disaster, after having defined risk and the risk society, then proceeding to analyze a range of disaster management models that are currently applied in Turkey and other countries. An empirical survey about the last major disaster that occurred in Turkey is carried out. Consequently, a new, effective and functional integrated disaster management model for Turkey is proposed. The term 'risk society' describes the inevitable new hazards produced by industrial society's process of development. The risk society brings not only hazards and risks that are not familiar and have not been faced before, but also prosperity and benefits for the members of the risk society. Natural and man-made disasters affect human beings more than in pre-industrial society and produce distinctive impacts on and changes in the psychological structure of urban society after disasters. The disaster management system applied in the risk society should be different from classical systems. While implementing a disaster management model, specific types of disaster that may occur in urban areas should be considered. The model should include swift response, efficiency and practicality. As a conclusion of all these studies, a new, effective disaster management model applicable to Turkey is proposed.Item Application of the composite variational principle to shallow water equations(Springer, 2011) Özer, Teoman; Machado, J. A. T.; Luo, A. C. J.; Barbosa, R. S.; Silva, M. F.; Figueiredo, L. B.; Yaşar, Emrullah; Uludağ Üniversitesi/Fen-Edebiyat Fakültesi/Matematik Anabilim Dalı.; 0000-0003-4732-5753; AAG-9947-2021; 23471031300In this study, we derive new local conservation laws of the one -layer shallow water equations in the plane flow which are belong to the family of evolution type equations by the composite variational principle of view in the development of the study.Item Applications of hecke operator to generalized dedekind eta functions(Amer Inst Pyhsics, 2009) Açıkgöz, Mehmet; Kim, Daeyeoul; Şimşek, Yılmaz; Simos, T. E.; Psihoyios, G.; Tsitouras, C.; Cangül, İsmail Naci; Uludağ Üniversitesi/Fen-Edebiyat Fakültesi/Matematik Anabilim Dalı.; 0000-0002-0700-5774; J-3505-2017; 57189022403The aim of this paper is to give relations between generalized Dedekind eta functions, theta functions, Dedekind sums, Hardy-Berndt sums and Hecke operators.Item An architecture for SCS: A specialized web crawler on the topic of security(Information Today, 2004) Özmutlu, Hüseyin Cenk; Özmutlu, Seda; Uludağ Üniversitesi/Mühendislik Fakültesi/Endüstri Mühendisliği Bölümü.; ABH-5209-2020; AAH-4480-2021; 6603061328; 6603660605Mining for correct and relevant information in the World Wide Web is a difficult task, handled by Web crawlers. This study outlines the components of a specialized crawler on the topic of security (SCS) that heavily makes use of artificial neural networks and rule-based expert systems to establish successful focused crawling on the topic of security. SCS is designed to find, index and follow the updates of Web pages of interest, and proposes new approaches for reaching relevant pages, which might stay hidden to other crawling approaches. SCS consists of four new page explorers, a database of relevant pages, a relevance evaluator using artificial neural networks and an updater using rule-based expert systems. SCS is a multi-threaded multi-object Java Applet and Application combination with embedded SOL and PHP elements and is applicable on single or multiple machines through parallel processing with its expandable and modular structure.Item Atmospheric deposition of organochlorine pesticides by precipitation in a coastal area(Springer Heidelberg, 2016-04-13) Cindoruk, S. Sıddık; Öztürk, Erman; Uludağ Üniversitesi/Mühendislik Fakültesi/Çevre Mühendisliği Bölümü.; 0000-0001-7536-0332; 10339194600; 57220515952Wet deposition fluxes of organochlorine pesticides (OCPs) were determined for rain samples collected in a coastal area of Turkey. Seventeen precipitation samples were collected over a 1-year period from 2008 to 2009. Rainwater was accumulated at the beginning of rain events using real time monitoring. Atmospheric concentrations were also measured in parallel with deposition samples. Both atmospheric concentrations and deposition fluxes were determined as particle and gas phases. The particle phase and dissolved phase deposition fluxes were 794.26 +/- 756.70 ngm(-2) day(-1) and 800.77 +/- 672.63 ngm(-2) day(-1), respectively. The washout ratios for OCP compounds were calculated separately for the particle and dissolved phases using the atmospheric concentrations and rain concentrations. The minimum washout ratio for the particle phase was 2339.47 for Endrin aldehyde, whereas the maximum washout ratio was 497593.34 for Methoxychlor. The maximum washout ratio for the dissolved phase was 247523.89 for Endosulfan beta, whereas the minimum washout ratio was 10169.69 for p,p'-DDT. The dry deposition velocities ranged from 0.01 to 1.67 cms(-1). The partitioning of wet deposition between the particle and dissolved phases was 50 % in terms of total OCP deposition.Item Atmospheric gas and particle phase concentrations of polychlorinated biphenyls (PCBs) in a suburban site of Bursa, Turkey(Taylor & Francis, 2008) Cindoruk, Sabahattin Sıddık; Taşdemir, Yücel; Uludağ Üniversitesi/Mühendislik Fakültesi/Çevre Mühendisliği Bölümü.; AAG-9468-2021; 10339194600; 6603118338Ambient air samples were collected between July 2004 and May 2005 with a high-volume air sampler (HVAS) in order to investigate the gas and particle concentration levels of polychlorinated biphenyls (PCBs) in a suburban site (the Uludag University Campus) in Bursa, Turkey. Average particle and gas-phase PCB concentrations (average +/- standard deviation) were 85.8 +/- 127.8 pg m(-3) and 328.1 +/- 284.2 pg m(-3), respectively. Total (gas+particle) PCB concentrations were higher in the warmer periods, while an opposite case was observed for the colder periods. The application of the Clausius-Clapeyron equation representing the relationship between gas-phase PCB concentrations and air temperature yielded a significant correlation. Moreover, the relationships between PCB congeners and meteorological variables were investigated. Based on meteorological variables and back trajectory results, evaporation and atmospheric transport were assumed to be the major sources of PCBs in the sampling site. PCBs are partitioned between gas and particle phases, and this fate was examined using different available approaches such as logK(P)-logP(Lo), logK(P)-logK(OA), and Junge-Pankow model. Shallow slopes between -0.18 and -0.48 were obtained from the logK(P)-logP(Lo) plot, while the slope of logK(P)-logK(OA) ranged from 0.2 to 0.42. P-Lo and K-OA values obtained from the literature were both considered good descriptors for determination of K-P experimental partitioning coefficient in the site. Correlations were significant at p<0.01 for all approaches.Item The beneficial effects of preperitoneal catheter analgesia following colon and rectal resections: A prospective, randomized, double-blind, placebo-controlled study(Springer, 2011-09) Öztürk, Ersin; Yılmazlar, Aysun; Coşkun, Funda; Işık, Özgen; Yılmazlar, Tuncay; Uludağ Üniversitesi/Tıp Fakültesi/Genel Cerrahi Anabilim Dalı.; Uludağ Üniversitesi/Tıp Fakültesi/Anesteziyoloji ve Reanimasyon Anabilim Dalı.; Uludağ Üniversitesi/Tıp Fakültesi/Akciğer Bilimleri Anabilim Dalı.; 0000-0002-9541-5035; 0000-0003-3604-8826; P-5779-2019; AAD-1271-2019; 35070171400; 55899579900; 21734137500; 36600543700; 6701800362Preperitoneal catheter analgesia following abdominal surgery has attracted interest in the last decade. We conducted this study to evaluate the benefits of preperitoneal catheter analgesia in managing pain after abdominal colon and rectal resections. A total of 50 patients undergoing colon and rectal resections for benign and malignant diseases received analgesic medicines via an epidural catheter placed just prior to surgery and a preperitoneal catheter placed at the end of the surgical procedure. Patients were instructed to use the epidural patient-controlled analgesia (PCA) device freely and were randomized into two groups after obtaining the approval of the Institutional Review Board: Group A received 10 ml of levobupivacaine twice a day postoperatively via preperitoneal catheter and group B received only 10 ml of saline. Demographics, surgical characteristics, pain scores recorded four days following surgery, analgesic volume used from the epidural PCA, clinical outcomes (length of stay, time to first bowel movement, time to first passage of gas or stool, time to first oral intake) and respiratory function test results (preoperative vs. postoperative) were compared. There were no significant differences in demographics or surgical characteristics between both groups. Pain scores were similar. Clinical outcomes and respiratory functions were comparable. The use of analgesic volume via epidural catheter was significantly lower in group A than in group B (P = 0.032). Preperitoneal catheter analgesia significantly decreased the need for epidural drug consumption and proved to be a beneficial adjunct for postoperative pain management of patients who underwent colon and rectal resections.Item Bilateral parotid-duct diversion using autologous vein grafts for the management of chronic drooling in cerebral palsy(Churchill Livingstone, 2002-09) Özgenel, Yeşim Güzin; Özcan, M.; Uludağ Üniversitesi/Tıp Fakültesi/Plastik ve Rekonstrüktif Cerrahi Anabilim Dalı.; 0000-0003-0000-8355; AAH-4233-2021; 6701823106; 7102067678Chronic drooling is a major problem in patients with cerebral palsy and other neurological dysfunctions. Various treatments, ranging from speech therapy to radical surgery, have been used to overcome this distressing problem, with surgery the most consistently successful. In this study, we used a new surgical technique to manage severe drooling. This involved the dissection of both parotid-duct orifices, and their relocation, via a submucosal tunnel, into the tonsillar pillar using autologous vein grafts. Four patients were treated using this technique together with bilateral submandibular duct rerouting. The results were analysed by subjective judgements of drooling and retrograde sialography at 90 days postoperatively. In all cases, salivary flow was reduced and drooling was significantly improved. Retrograde sialography revealed no signs of obstruction or stricture formation in any of the cases. No postoperative complications occurred. These preliminary results suggest that the bilateral surgical transposition of Stensen's ducts into the tonsillar pillar using autologous vein grafts together with bilateral submandibular duct rerouting can provide effective control of chronic drooling.

Although Turkey has wide spectrum of energy resources, these resources are insufficient in terms of usage, and Turkey is currently an energy importing country. Approximately 75% of our country's energy consumption met by imports and the share of imports continues to increase each year. According to the literature, although approximately 50 to 65 Million Tonnes of Oil Equivalent (MTOE) agricultural waste and 11.05 MTOE animal wastes were produced and 60% of this value can be used for energy production, they are not assessed. It is known that, energy potential to be obtained from agricultural and animal waste can cover 22-27% of Turkey's annual energy consumption. In 2010, primary energy demand in Turkey was 109.266 MTOEwhile energy production value 32.228 MTOE. Energy demand in Turkey shows an increase of 8-10% annually, and it is estimated that in 2020 primary energy demand will reach 298,4MTOEwhile energy production will be 70.2 MTOE, and energy import will be 76 %. In this study, the capacities of the collected and grouped agricultural organic waste were determined in Turkey and in Bursa, which is the fourth largest city in Turkey. According to these capacities, valuable organic matter amounts and amount of energy were calculated
