In this study, an experimental work is. presented to determine the effects of two different fancy yarn structures (chenille and macaroni) and four different raw materials (acrilic, cotton, polyester and viscose) on the abrasion and tensile propertries of woven upholstery fabrics. Results were evaluated by SPSS statistical program. All test results were assessed at a confidence level of at least 95% (at most 5% significance level). The abrasion resistance and tenacity values of chenille and macaroni yarns were measured too. Abrasion resistance and tenacity values of chenille and macaroni yarns are affected significantly by material type and fancy yarn structure. Macaroni yarns show higher. weight loss (%) ratio and tenacity values than chenille yams. Thickness values of chenille fabrics are higher than macaroni fabrics. Weight loss (%) values of chenille fabrics are higher than macaroni fabrics. The macaroni fabrics show higher stress values at max. load than chenille fabrics. The cotton and polyester yarns. are abraded less than others. Polyester yams and fabrics show the highest tensile strength values. Viscose yarns and fabrics less resistant to abrasion.

(Edam, 2016-11-03) Aydın, Bünyemin; Özbilen, Ömer; Erdoğan, Güneş; Memnun, Dilek Sezgin; Uludağ Üniversitesi/Eğitim Fakültesi/İlköğretim Bölümü.; 0000-0003-3254-8858; ABG-5519-2020; F-4256-2014; K-3286-2015; 57193887049
The RBC+C abstraction model is an effective model in mathematics education because it gives the opportunity to analyze research data through cognitive actions. For this reason, we aim to examine the abstraction process of the limit knowledge of two volunteer participant students using the RBC+C abstraction model. With this aim, the students' abstraction processes were examined over recognition, building-with, construction, and consolidation. In the process, three problems that enable students to use their pre-knowledge were designed by the researchers to reveal the students' mathematical thinking levels, abstraction processes, and finally to improve a new structure. These problems were used in the application, and students' dialogues were video-recorded. The semi-constructed interview and observation data-collection methods were used in this process, and one of the researchers participated in the study as a participant observer. The data was analyzed and interpreted by transcribing the video recordings into written text and grouping them into the cognitive actions of the RBC+C model. In conclusion, these students were indicated to have managed recognizing and building-with their pre-knowledge on sequence, function, and infinity, and thus constructing knowledge on limits.
Acid proteinase enzyme activity in Candida albicans strains: A comparison of spectrophotometry and plate methods
(TÜBİTAK, 2011) Akçağlar, Sevim; Ener, Beyza; Töre, Okan; Uludağ Üniversitesi/Tıp Fakültesi/Mikrobiyoloji ve Enfeksiyon Hastalıkları Anabilim Dalı.; 0000-0002-4803-8206; AAG-8523-2021; 6506194958; 15053025300; 6505909596
In recent years, the incidence of fungal infections has been rising all over the world. Although the amount of research in the field of pathogenic fungi has also increased, there is still a need for studies on fungal virulence. In this investigation, we focused on testing bloodstream-identified Candida albicans in experimental in vitro virulence assays. The proteinase enzyme activities of 30 C. albicans strains isolated from the bloodstream and sterile body fluids were investigated (15 colonizations, 15 infections). The spectrophotometric and plate methods were used to determine proteinase activity. The correlations between the 2 methods were compared. This study indicates that, in terms of proteinase activity, there were no statistically significant differences between strains obtained from infection and colonization sites by either method (P > 0.05).

(Küre İletişim Grubu, 2015-07-06) Pehlivan, Sultan; Eren, Bülent; Akyol, Sümeyya; Eren, Filiz; Tagil, Süleyman Murat; Demircan, Kadir; Fedakar, Recep; İnanır, Nursel Türkmen; Gürses, Murat Serdar; Ural, Mustafa Numan; Uludağ Üniversitesi/Tıp Fakültesi/Adli Tıp Anabilim Dalı.; 0000-0002-9982-0476; AAC-8913-2020; AAH-6287-2021; 8725968900; 56712925300; 55979536300; 57163358100
Objective: Recent studies performed in the central nervous system highlight the pathophysiological relevance of A disintegrin-like and metalloproteinase with thrombospondin motifs (ADAMTS) genes and their protein products. The determination of alterations in expression profiles of ADAMTS family genes in Alzheimer's disease (AD) patients may contribute to the explanation of tissue pathology and also new ideas for remedial approaches for this incurable but preventable disease. Therefore, the goal of this study was to describe and identify the distribution, characteristics, and any changes in the expression, in other words, immunoreactivity, for aggrecanases (ADAMTS4, 5, 9, and 15) proteins in AD brain. Methods: Nine cases that were autopsied in the Council of Forensic Medicine, Bursa Morgue Department in 2013, were selected. All of the cases were sent for autopsy to the institution within 8 hours after death. At autopsy, tissue samples were obtained for histopathological examination of organs for determining the cause of death. Out of these, two cases were diagnosed with AD by neurologists when they were alive. Immunohistochemical staining was performed on the brain slides by using relevant primary and secondary antibodies against aggrecanase proteins. All images were acquired using a X200 objective of a microscope (Olympus BX53) and evaluated by the staining intensity using a semi-quantitative scoring system. Results: ADAMTS4 and 5 were slightly under-expressed in the brains from autopsied AD cases compared to those of control brains and suggested that extracellular matrix (ECM) degradation was not endorsed in AD brain. On the other hand, ADAMTS9 and 15 aggrecanases were not found to be expressed in correspondent brain sections of AD and control cases. Conclusion: The current study demonstrated that some aggrecanases were found to be under-expressed in AD brains. Additional studies in which all ADAMTS enzymes will be studied in terms of mRNA and protein levels are needed to understand the relative contributions of ADAMTS genes and proteins in AD brains.

(Scientific and Technological Research Council Turkey, 2015) Tosunoğlu, Aycan; Babayiğit, Sinan; Bıcakcı, Adem; Uludağ Üniversitesi/Fen-Edebiyat Fakültesi/Biyoloji ve Botanik Bölümü; Uludağ Üniversitesi/Büyükorhan Meslek Yüksekokulu; 0000-0003-2303-672X; 0000-0002-8825-9425; 0000-0002-6333-3123; GDS-1748-2022; JCE-8599-2023; O-1244-2018; 35235434000; 56450939000; 6701674542
An aeropalynological survey of the atmosphere of Buyukorhan in Bursa Province was carried out from January 2012 to December 2013 using a Durham gravimetric sampler. The number of pollen grains per cm(2) was calculated on a weekly basis. Over 2 years a total of 13,274 pollen grains/cm(2) from 44 taxa, including 24 arboreal plants (APs) and 20 nonarboreal plants (NAPs), and unidentified pollen grains were recorded. In 2012 and 2013, respectively, 5159 and 8115 pollen grains were recorded. The pollen grains consisted of 87.46% APs, 12.20% NAPs, and 0.35% unidentified plants. Pinus, Cupressaceae/Taxaceae, Quercus, Poaceae, Morus, Plantago, Olea europaea, and Cedrus were responsible for the highest pollen amounts in the study area. The highest number of pollen grains (49.84%) was recorded during May.

(TÜBİTAK, 2013-03-15) Yenigün, Ayşe; Eliaçık, Kayı; Tosunoǧlu, Aycan; Bıçakçı, Adem; Uludağ Üniversitesi/Fen-Edebiyat Fakültesi/Biyoloji Bölümü.; 0000-0002-6333-3123; O-1244-2018; 35235434000; 6701674542
Atmospheric pollen grains of Kusadasi were captured using Durham samplers and investigated in 2005. The total number of pollen grains and the pollen grains/cm(2) were calculated from slides that were changed weekly. During the study period a total of 12,980 pollen grains/cm(2) belonging to 44 identified taxa and unidentified pollen grains were recorded at 2 stations. At the first station (Si), 7346 pollen grains were counted per cm(2), while only 5634 pollen grains were counted at the second station (S2). The majority of the investigated pollen grains were from Olea europaea L. (34.46%), Cupressaceae/Taxaceae (30.04%), Pinus spp. (19.71%), Platanus spp. (4.41%), Poaceae (3.70%), and Mortis spp. (1.22%). In addition, 41.22% of the annual pollen index was captured in May. According to our results, seasonal pollen durations for the predominant pollen grains in Kusadasi were as follows: nearly the whole year for Cupressaceae/Taxaceae, Pinus spp., and Poaceae; March-September (between the 17th and 35th weeks) for Olea europaea; March-May (between the 11th and 21st weeks) for Platanus spp.; and March-April (between the 11th and 17th weeks) for Morus spp.
Allergenic pollens in Turkey
(Bilimsel Tıp Yayınevi, 2019) Bıçakçı, Adem; Tosunoğlu, Aycan; Uludağ Üniversitesi/Fen-Edebiyat Fakültesi/Biyoloji Bölümü.; 0000-0002-6333-3123; 0000-0003-2303-672X; O-1244-2018; 6701674542; 35235434000
In this study, atmospheric pollen data of previous studies belonging to 54 different stations in Turkey, conducted by using the gravimetric and/or volumetric method, were evaluated in terms of flora, biogeography and aeropalynology. In line with these data, Turkey is divided into 5 aeropalyno-geographical regions, which are represented with their characteristics (North, West, South, Central, and East), and the skin prick tests were evaluated on the basis of pollen allergy data regionally and concurrently. In general, the dominant pollen seen in Turkey's atmosphere has been found to be represented by 29 different types. The pollen sum of these 29 taxa was found to represent more than 85% of the total pollen concentration detected in the atmosphere when evaluated according to different regions. Of these pollen types, 20 belong to woody and nine belong to herbaceous plants. It has generally been reported that there are higher pollen concentrations of woody plants in the atmosphere in Turkey. Overall, Cupressaceae/Taxaceae, Pinus, and Gramineae pollens were found as the common types to all of Turkey's five aeropalyno-geographic regions, in which they were recorded within the first three dominant pollen types. It has also been observed that Quercus, Platanus and Populus pollens from woody plants, and Amaranthaceae and Urticaceae pollens from the herbaceous plants were commonly recorded in high amounts for all regions. However, when the revised data are examined in detail, it has been determined that tree pollens like Fagus, Carpinus, Alnus, Corylus and Betula in the atmosphere were characteristic for the Northern Turkey region; the highest amounts of Olea europaea pollen for the Western Turkey region; higher quantities of the Cupressaceae/Taxaceae pollen for the Southern Turkey region; and very high amounts of Gramineae, Morus, Fraxinus and Artemisia pollens for the Eastern Turkey region have been recorded as characteristic in the atmosphere. Compared to Europe; Morus, Salix, Populus, Mercurialis and Plantago pollens in the atmosphere of Turkey differ in their presence and quantity. On the other hand, invasive plants such as Ambrosia and Ailanthus or exotic plants such as Casuarina and Eucalyptus, which have allergenic pollens, must be remembered among the dominant taxa in the air in different regions on a seasonal basis. It has been shown that the ideal allergen panels have to be updated according to the area and especially by including the dominant taxa. However, these updates should be made by taking into account cross-reactions, and at least one of the reacting taxa should be included in the panel.

(TÜBİTAK, 2011) Aybeke, Mehmet; Erkan, Perihan; Bıçakçı, Adem B.; Malyer, Hulusi; Uludağ Üniversitesi/Fen-Edebiyat Fakültesi/Biyoloji Bölümü.; 0000-0002-6333-3123; 0000-0002-8837-3375; O-1244-2018; AAK-4004-2021; 8401289600; 6701674542; 6602736554
A continuous aeropalynological survey of the atmosphere of Kirklareli was carried out from January 2002 to December 2003 by means of the gravimetric method using Durham apparatus. Weekly pollen grains in per cm(2) were calculated. During these 2 years, a total of 11,758 pollen grains were recorded. Pollen fall in the years 2002-2003 comprised grains belonging 46 taxa. Of these taxa, 26 belonged to arboreal and 20 taxa non-arboreal plants. In 2002, 6011 pollen grains and, in 2003, 5747 pollen grains were recorded. Total pollen grains consisted of 71.02% grains from arboreal plants, 28.93% grains from non-arboreal plants, and 0.05% unidentified pollen grains. Pollen from the following taxa we also found to be prevalent in the atmosphere of Kirklareli: Pinus spp., Cupressaceae/Taxaceae, Gramineae, Quercus spp., Chenopodiaceae/Amaranthaceae, Plantago spp., Platanus spp., Aesculus spp., Xanthium spp., Fagus spp., Robinia spp., Urticaceae, Betula spp., and Oleaceae, Artemisia spp. A total of 64.95% pollen grains appeared during April to June. The pollen calendar for the region presented in this paper may be useful for allergologists to make an exact diagnosis.

BACKGROUND In this study, our aim was to identify the validity of the prophylaxis indications for patients who received tetanus prophylaxis, determine the ratio of high-risk wounds to the number of patients with immunity, and to evaluate the tetanus immunity of specific age groups. METHODS Patients who applied to the Emergency Department (ED) between September 2009 and May 2010 and who were considered for tetanus prophylaxis by his/her primary care physician were included in the study. RESULTS A total of 320 patients were evaluated. The average age of the patients was 40.87 +/- 15.83 years. A total of 73.1% of the patients were male and 26.8% were female. A total of 40.3% of the patients knew their vaccination history, while 59.7% had no recollection of their vaccination history. 14.7% of the patients had received their last dose within 5 years and 48.1% within 5-10 years; 37.2% of the patients declared that more 10 years had passed since their last vaccination. In 75% of the patients, the tetanus immunoglobulin (Ig)G level was identified as >= 0.1 IU/ml, while 25% of the patients had levels <0.1 IU/ml. The number of patients with protective levels was lower among those who were illiterate or who had only a primary school education, and this difference was statistically significant (p<0.001). CONCLUSION The vaccination histories can be misleading. Certain equipment can be used at the bedside to determine a patient's tetanus immunization status.

(Natl Inst Optoelectronics, 2016-11-25) Günday, Abdurrahman; Karlık, Sait Eser; Yılmaz, Güneş; Uludağ Üniversitesi/Orhangazi Meslek Yüksekokulu/Elektronik Teknolojisi Programı.; Uludağ Üniversitesi/Mühendislik Fakültesi/Elektrik-Elektronik Mühendisliği Bölümü.; AAH-5448-2021; AAJ-2404-2021; 55747963900; 10043513300; 6504559945
Brillouin scattering mechanism and Young modulus variations in optical fiber distributed sensing systems are directly affected by ambient temperature and thermal strain formations. Generally, in such sensing systems where temperature and strain formations are detected and measured simultaneously, Brillouin frequency shift and Brillouin power changes of backscattered optical signal are used due to their temperature and strain dependencies. In this research, a different point of view has been developed and effects of Young modulus variations of the sensing fiber core on the Brillouin power and the Brillouin frequency shift changes have been analyzed. In this study, positioning five heating units at different locations along a 1000 m G.652 type single-mode fiber operating at 1550 nm, a sensing system model has been constructed. On this model, simulations related to Young modulus variations along the sensing fiber depending on temperature fluctuations generated by heating units have been performed using Matlab 2010 and results have been obtained for 1000 different points with a spatial resolution of 1 m. For 40 degrees C- 47 degrees C operating temperature range of the sensing fiber, the Young modulus of the fiber core changes from 73.205 GPa to 73.283 GPa. Furthermore, using the analytical method, linear formula between the Young modulus and Brillouin parameters, i.e. Brillouin power and Brillouin frequency shift changes, of the backscattered optical signal have been derived. Thus, for the system model constructed, Matlab simulations analyzing relations between Young modulus variations and Brillouin parameter changes have been performed under specified operating conditions. For Young modulus variations in 73.205 GPa - 73.283 GPa range, values of Brillouin power and Brillouin frequency shift changes have been obtained in ranges of 13.950 % - 16.273 % and 69.00 MHz - 85.72 MHz, respectively. Moreover, temperature and thermal strain resolutions along the sensing fiber have been acquired as similar to 0.7 degrees C and similar to 40 mu epsilon, respectively.
Analysis of the necessity of routine tests in trauma patients in the emergency department
(Türk Travma ve Acil Cerrahi Derneği, 2012-01) Köksal, Özlem; Çevik, Şebnem Eren; Aydın, Şule Akköse; Özdemir, Fatma; Uludağ Üniversitesi/Tıp Fakültesi/Acil Tıp Anabilim Dalı.; 0000-0003-2271-5659; 0000-0001-7602-8104; AAK-8332-2020; 23389880200; 54894485300; 15757217900; 7006765911
BACKGROUND: The necessity of routine tests as regarded in the Advanced Trauma Life Support protocols has become controversial in recent years. The aim of this study was to analyze the necessity of routine tests in trauma patients. METHODS: This was a prospective study. A total of 103 blunt trauma patients aged between 15 and 65 years who presented to the emergency department with major trauma, Glasgow Coma Scale of 15 and Revised Trauma Score of 12 were admitted to the study. RESULTS: The average age of the patients (30.1% female, 69.9% male) was 35 +/- 12.97 years. A total of 72.8% of the patients presented for motor vehicle crashes, 12.6% for pedestrian injury and 14.6% for fall from a height. All of the routine tests were evaluated separately. With the exception of cervical examination-lateral cervical X-ray results and pelvic examination-complete blood count and urinalysis test results, significant relations were determined between the reason for requiring a test and the results of the other tests (complete blood count, lateral cervical X-ray and abdominal ultrasonography). CONCLUSION: According to our study, biochemical tests, anterior-posterior chest X-ray and anterior-posterior pelvic X-ray can be ordered as targeted tests. Conducting targeted tests will reduce costs and workload.
Analysis of the relationship between moral judgment competences and empathic skills of university students
(EDAM, 2010) Çiftçi, Nermin Arıdağ; Yüksel, Asuman; Uludağ Üniversitesi/Eğitim Fakültesi/Eğitim Bilimleri Bölümü.; 36024602700
The aim of this study is to analyse whether there is a significant relationship between moral judgment competence and empathic skills of the students studying at Uludag University. In this article, the results of two researches carried out on two different samples are presented. In the first research, data were collected using David's Interpersonal Reactivity Index (IRI) and Lind's Moral Judgment Test (MJT) and the participants were 68 female and 61 male students between the ages of 20 and 29 (average: 22.85) who are studying in different departments in the Faculty of Education at Uludag University. The second research was conducted on 294 female and 141 male students between the ages of 18 and 30 (average: 22.30) who are studying in different faculties of Uludag University. Data were gathered by using Dokmen's Empathic Skill Scale (ESS) and Lind's Moral Judgment Test (MJT). In the two separate studies there was no significant relationship between students' moral test points and their general empathy points. The analysis of the relationship between the moral judgment test points of students whose Interpersonal Reactivity Index (IRI) points are between the top and bottom 27 percent segments revealed a significant negative relationship (r=.45.6; p>0.01) between the points students got from the 'personal distress' subscale and the ones they got from the 'workers' dilemma' subscale of the moral judgment test. Data were discussed in accordance with the relevant literature that focuses on the relationship between moral judgment and empathy.
Anatomical study of the cavernous sinus emphasizing operative approaches
(Türk Nöroşirürji Derneği, 2010-04) Boyacı, Suat; Aksoy, Kaya; Dalgıç, Adem; Uludağ Üniversitesi/Tıp Fakültesi/Beyin ve Sinir Cerrahisi Anabilim Dalı.; 36135211700
AIM: The aim of this article is to describe the microsurgical anatomy of the cavernous sinus, the triangles, and the osseous relationships in the region with special attention to the relationships important in surgical approaches on the intracavernous structures. MATERIAL and METHODS: Fifty cavernous sinuses obtained from twenty-five cadaver heads were studied in detail using magnification. Stepwise dissections of the cavernous sinuses performed to demonstrate the intradural and extradural routes, anatomy of the triangles and osseous relationships in the region. RESULTS: The main branches of the intracavernous portion of the carotid artery were the meningohypophyseal, the inferior cavernous sinus, and McConnell's capsular artery. The main branches of the meningohypophyseal trunk were the tentorial, the dorsal meningeal, and the inferior hypophyseal artery. There were variations of the main branches of the meningohypophyseal trunk. The sixth cranial may splite into rootlets as it passes lateral to the carotid artery. There were size and shape variation of the triangles. CONCLUSION: A precise understanding of the bony relationships, the anatomy of the triangels and neurovascular content of the cavernous sinus, together with the use of cranial base and microsurgical techniques are necessary for safer surgery. A single approach is not capable of providing exposure of all parts of the sinus.
Anti-invariant Riemannian submersions from Kenmotsu manifolds onto Riemannian manifolds
(TÜBİTAK, 2015-09-04) Beri, Ayşe; Erken, İrem Küpeli; Murathan, Cengizhan; Uludağ Üniversitesi/Fen-Edebiyat Fakültesi/Matematik Bölümü.; ABE-8167-2020; ABH-3658-2020; 57188979076; 55623226100; 6506718146
The purpose of this paper is to study anti-invariant Riemannian submersions from Kenmotsu manifolds onto Riemannian manifolds. Several fundamental results in this respect are proved. The integrability of the distributions and the geometry of foliations are investigated. We proved the nonexistence of (anti-invariant) Riemannian submersions from Kenmotsu manifolds onto Riemannian manifolds such that the characteristic vector field xi is a vertical vector field. We gave a method to get horizontally conformal submersion examples from warped product manifolds onto Riemannian manifolds. Furthermore, we presented an example of anti-invariant Riemannian submersions in the case where the characteristic vector field xi is a horizontal vector field and an anti-invariant horizontally conformal submersion such that is a vertical vector field.

Objectives: This study aims to compare the antibiotic release and biological effectiveness of bead type and articulating spacers of different cement types with antibiotics added at alternative phases of cement preparation. Materials and methods: Four gram vancomycin was added into two types of antibiotic-free cement (Simplex®, Biomet®) with similar viscosity and also gentamycin-containing cement (Refobacin®). Prepared specimens were used to create cement beads and articulating hip spacers, making a total of six different groups. Two alternative groups were formed by adding the Vancomycin while the cement was in dough phase. Antibiotic release and biological activity were evaluated with immunoassay techniques and agar-disk diffusion methods. Results: All groups showed initial antibiotics surge in the first week, which was 2 to 4 times more evident in the beads group. Antibiotic release and change in release rate were significantly different between Simplexalternative and Simplex, Biomet, Refobacin-beads, and between Biometspacer and Refobacin-beads groups (p<0.05). Elution of antibiotics was not different between mobile spacers prepared with conventional or alternative methods (p>0.05). Biomet cement showed larger diffusion inhibition zone in agar. There was no difference between biological activity of the bead and mobile designs of the Biomet brand (p>0.05). Inhibition zone analyses of agar and disk diffusion tests revealed significant differences between several groups (p<0.05). Conclusion: Cement beads provide superior antibiotic release regardless of cement type or preparation method. Simplex P® cement has lower anti-bacterial efficiency than Biomet®. Different methods for cement and antibiotics mixing and addition of extra vancomycin into the commercially drug loaded cement do not have any effect on the results.

The aim of this study was to examine the relationship between antibiotic resistance patterns among Salmonella enterica subsp. enterica Serovar Enteritidis isolates (Salmonella Enteritidis) of human and poultry origin. Antibiotic resistance of 97 Salmonella Enteritidis isolates from 25 chicken meat. 25 chicken intestine and 47 human fecal samples was examined using the National Committee for Clinical Laboratory Standards (NCCLS, 1997) disk diffusion method. Resistance patterns of the isolates were as follows: Of the 25 chicken meat isolates 4 were resistant to some antibiotics. Two isolates (CM 15 and CM22) were resistant to ampicillin (AMP), cefuroxime sodium (CXM), ceftriaxone (CRO), trimethoprim-sulphamethazole (SXT) and ampicillin-sulbactam (SAM). Of the other 2 isolates, CM20 showed resistance to ceftriaxone (CRO) and CM23 was resistant to chloromphenicol (C) and cephalexime (CL). Eight human isolates showed 4 different resistance patterns. Five (HF3, HF19, HF20, HF22, and HF25) were resistant to ampicillin (AMP), ampicillin-sulbactam (SAM), tetracycline (TE) and chloromphenicol (C), while resistance to chloromphenicol (C) and cephalexime (CL) was observed in HF32 and HF46. HF13 was resistant to both ampicillin (AMP) and ampicillin-sulbactam (SAM). One of the chicken intestinal isolates was found to be resistant only to cefuroxime sodium (CXM). There was no relationship between antibiotic resistance patterns for Salmonella isolates of different origins. Multiple antibiotic resistance patterns were observed in some isolates. It is important that some isolates of chicken intestine and meat origin showed resistance to antibiotics being used in humans.
