Are Euclidean Distance and Network Distance Related ?

Although spatial distance is a very important concept for a wide variety of disciplines including social, natural, and information sciences, the methods used to measure spatial distance are not directly expressed and fully explained. In this study, we calculate and compare Euclidean distances and network distances for 10 randomly selected European cities. On the contrary to the findings reported in past research, we find that there is not a global straight forward relation between the Euclidian distance and network distance.© 2016. The Authors.

Examination of the Relationship between Urban Air Pollution and Urban Planning Decisions in Cigli Case, Izmir (Turkey)

The air pollution problem remains, although significant improvements have been seen in urban air quality over the last years. Despite the size and variety of studies on urban air pollution, the usage of spatial statistics has been extremely limited. This study aims to show that the spatial statistic techniques can well be used to examine and explain the air pollution levels in urban areas. The data for the sulphur dioxide (SO2) and nitrogen dioxide (NO2) concentrations are measures using passive diffusion tubes at the 67 monitoring sites in the district of Çiğli (Izmir), which are selected through a spatial systematic sampling process. The tubes were exposed for a 2-week period in August 2015. For the determination of the level of clustering for high values and low values of SO2 and NO2 concentrations, Getis-Ord G* local statistics are calculated. There are five points with high values of SO2 surrounded by low values, three points of NO2, where the results are statistically significant at the 0.10 level. The findings indicate that the presence of the industrial zone, the form of fossil fuels (coal or natural gas) used in heating, and topography are the strong determinants urban air pollution.© 2016.

Promjena nekih biokemijskih vrijednosti u Honamli koza i dugodlakih koza u vrijeme spolnog sazrijevanja.

Honamlı goats have been defined and recorded as a new breed but the literature is very limited on these goats. In terms of meat production, they have been reported as having some of the highest potential among the goat breeds in Turkey. The aim of the present study was to determine the alterations in blood serum chemistry values in the puberty period in Honamlı and Native Hair goats. Selected biochemistry parameters were chosen due to their association with meat production potential. Blood samples of Honamlı (n = 90, 45 animals for each sex) and Native Hair goats (n = 90, 45 animals for each sex) were obtained from goat herds in the Western Mediterranean region of Turkey. The values of alkaline phosphatase (ALP), alanine transaminase (ALT), aspartate transaminase (AST), creatine kinase (CK), calcium, cholesterol, creatinine, iron, magnesium, phosphorus, total lipids, triglycerides and uric acid were measured in the sera obtained from blood samples of males and females in equal numbers of each species, in the three age groups of 4, 8 and 12 months. One-way analysis of variance and the Tukey test were performed for statistical evaluation. In both male and female animals, ALT, AST, CK, calcium, cholesterol, creatinine, iron, magnesium, phosphorus, total lipids, triglycerides and uric acid levels exhibited significant (P<0.05) differences between the age groups. Our findings suggest that there are age-associated parallel increases of ALT values in female goats and total lipid values in male goats. The present study also reveals that the analyzed biochemical values usually change after 4 months of age when compared with the other age groups.Honamli koza je nova pasmina koza pa su literaturni podatci o njoj vrlo oskudni. Jedna je od pasmina s najvećim mogućnostima za proizvodnju mesa u Turskoj. Cilj je ovog rada odrediti promjene biokemijskih vrijednosti u krvnom serumu Honamli koza i dugodlakih koza za vrijeme spolnog sazrijevanja. Za istraživanje su odabrani neki biokemijski pokazatelji povezani s proizvodnjom mesa. Uzorci krvi Honamli koza (n = 90, po 45 životinja oba spola) i dugodlakih koza (n = 90, po 45 životinja oba spola) uzeti su od stada u Zapadnom Mediteranskom području Turske. Vrijednosti alkalne fosfataze (ALP), alanin transaminaze (ALT), aspartat transaminaze (AST), kreatin kinaze (CK), kalcija, kolesterola, kreatinina, željeza, magnezija, fosfora, ukupnih lipida, triglicerida i mokraćne kiseline izmjerene su u uzorcima seruma uzetima od muških i ženskih životinja obiju pasmina podijeljenih u skupine prema dobi od 4, 8 i 12 mjeseci. Jednostavna analiza varijance i Tukeyev test rabljeni su za statističku obradbu podataka. I u muških i u ženskih životinja ustanovljene su značajne razlike (P<0,05) među dobnim skupinama za razine ALT, AST, CK, kalcija, kolesterola, kreatinina, željeza, magnezija, fosfora, ukupnih lipida, triglicerida i mokraćne kiseline. Nalazi pokazuju usporedno povećanje vrijednosti ALT u ženskih životinja i vrijednosti ukupnih lipida u muških životinja. Analizirane biokemijske vrijednosti obično se mijenjaju nakon 4 mjeseca starosti u usporedbi s drugim dobnim skupinama

A Material Perspective on Consequence of Deformation Heating During Stamping of DP Steels

Recent studies showed that, during stamping of high strength steels at industrially relevant production rates, local temperature in the blank may rise up to 200°C – 300°C due to deformation heating. Moreover, die temperature may also rise up to 100°C – 150°C for progressive stamping dies. Based on the common assumption that the blank softens as the temperature increases, thermal softening creates a margin in Forming Limit Diagram (FLD) and therefore the FLD determined at room temperature can safely be used for those cases. In this article, the validity of this assumption on DP590 steel is questioned by high temperature tensile tests (RT - 300°C) at various strain rates (10-3 s-1 – 1 s-1). The results indicated a decrease both in uniform and total elongation in 200°C – 300°C range together with several other symptoms of Dynamic Strain Aging (DSA) at all strain rates. Concurrent with the DSA, the simulated FLD confirms the lower formability at high temperature and strain rates. Thus, it is concluded FLD determined at RT may not be valid for the investigated steels

Détermination de l’expression des gènes codant pour le TNF-α et la leptine par RT-PCR dans le sang de vaches présentant un déplacement de la caillette à gauche

The aims of this study are to evaluate the TNF-α and leptin gene expression in blood from Holstein cows with left abomasal displacement and to correlate it with induced liver injury. The TNF-α and leptin expression in blood samples was determined by RT-PCR after normalisation using the constant expression of the housekeeping GAPDH gene in cows with left abomasal displacement (LAD) (n = 20) before surgery and 7 days after as well as in healthy controls (n = 10). Plasma hepatic enzyme (AST: aspartate aminotransferase, ALT: alanine aminotransferase and ALP: alkaline phosphatase) activities were measured in parallel. Plasma AST and ALP activities dramatically increased in diseased cows during the preoperative period and then declined. Although not significantly, the leptin expression tended to decrease in LAD affected cows while the TNF-α expression tended to increase during the postoperative period. These results suggest that TNF-α may be associated with liver damage during abomasal displacement and that leptin was inversely correlated.Les objectifs de cette étude ont été d’évaluer l’expression des gènes codant pour le TNF-α et la leptine dans le sang de vaches Holstein présentant un déplacement à gauche de la caillette et de la corréler avec les lésions hépatiques induites. L’expression du TNF-α et de la leptine a été déterminée par RT-PCR après normalisation en considérant l’expression du gène de ménage GAPDH comme constante dans les échantillons sanguins provenant de vaches atteintes d’un déplacement à gauche de la caillette (n = 20) avant et 7 jours après traitement chirurgical ou provenant de vaches saines (témoins, n = 10). Les activités plasmatiques des enzymes hépatiques (AST : aspartate aminotransférase, ALT ; alanine aminotransférase et PAL : phosphatase alcaline) ont été mesurées en parallèle. Les activités plasmatiques de l’AST et de la PAL étaient considérablement augmentées chez les vaches malades avant la chirurgie puis elles ont diminué durant la période postopératoire. Bien que les variations n’aient pas été significatives, l’expression de la leptine chez les animaux malades a tendu à diminuer alors que celle du TNF-α a augmenté durant la période postopératoire. Ces résultats suggèrent que le TNF-α pourrait être associé aux lésions hépatiques associées à un déplacement de la caillette alors que la leptine serait inversement corrélée.Scientific Research Projects Commission of Mehmet Akif Ersoy Universit

Solitary Fibrous Tumors of Chest: Another Look with the Oncologic Perspective

Solitary fibrous tumors are mesenchymal lesions that arise at a variety of sites, most commonly the pleura. Most patients are asymptomatic at diagnosis, with lesions being detected incidentally. Nevertheless, some patients present due to symptoms from local tumor compression (eg. of the airways and pulmonary parenchyma). Furthermore, radiological methods are not always conclusive in making a diagnosis, and thus, pathological analysis is often required. In the past three decades, immunohistochemical techniques have provided a gold standard in solitary fibrous tumor diagnosis. The signature marker of solitary fibrous tumor is the presence of the NAB2-STAT6 fusion that can be reliably detected with a STAT6 antibody. While solitary fibrous tumors are most often benign, they can be malignant in 10-20% of the cases. Unfortunately, histological parameters are not always predictive of benign vs malignant solitary fibrous tumors. As solitary fibrous tumors are generally regarded as relatively chemoresistant tumors; treatment is often limited to localized treatment modalities. The optimal treatment of solitary fibrous tumors appears to be complete surgical resection for both primary and local recurrent disease. However, in cases of suboptimal resection, large disease burden, or advanced recurrence, a multidisciplinary approach may be preferable. Specifically, radiotherapy for inoperable local disease can provide palliation/shrinkage. Given their sometimes -unpredictable and often- protracted clinical course, long-term follow-up post-resection is recommended

Comparison of posterior cranial fossa morphometric measurements in Chiari type I patients with and without syrinx cavity on magnetic resonance imaging

Purpose: To compare the posterior fossa measurements of Chiari type I malformation (CHM1) patients with and without syrinx and with a control group. Material and methods: The patients with syrinx were divided into 2 groupd according to syrinx width/cord width (S/C) ratios: group 1 – S/C ratio 50%. The length of the clivus, the AP length of the foramen magnum, the AP length of the posterior fossa, the perpendicular distance between the McRae line and (a) the splenium of corpus callosum, (b) the pons, and (c) the fastigium of the 160 patients and of the 160 control patients were statistically compared. In addition, the measurements of the patients with and without syrinx, according to the S/C ratio, were statistically compared. Results: Syrinx was present in 59 (36.8 %) of the 160 patients. The S/C ratio was 50% in 29 (49.1%) of them. All the measurements in the patient group, except of the AP length of the foramen magnum, were statistically significantly lower than in the control group (p = 0.001). There was no signif icant difference in the measurements of the patients with syrinx group 1 and the patients without syrinx, but the AP length of posterior fossa was statistically significantly lower in the patients with syrinx group 2 than the patients without syrinx (p = 0.03). Conclusion: The S/C ratio can be a guide to the underlying aetiology

Nutritional Habits According to Human Chronotype and Nutritional Status of Morningness and Eveningness

Sixty one female and eighty one male volunteers participated in the study that aims to assess the nutrition habits according to human chronotype and nutritional status of morningness and eveningness. Chronotype was assessed by Turkish version of the Morningness-Eveningness Questionnaire and the other questionnaire prepared to assess of nutritional habits of participants were used. Furthermore a three-day food record for assessment of nutritional status was completed by twelve male who were definite morning/moderate morning types and eleven male who were definite evening/moderate evening types. According to a three-day food record intake of daily total energy (kkal), fat (g) and carbohydrates (g) were higher and intake of protein (% energy) was lower in the evening types (p<0,05). In conclusion, evening chronotype was associated with inadequate dietary habits and status such as high daily energy (kkal), fat (g) and carbohydrates (g) intakes and low protein intake (% energy) and skipped meal

Flavor Phenomenology in General 5D Warped Spaces

We have considered a general 5D warped model with SM fields propagating in the bulk and computed explicit expressions for oblique and non-oblique electroweak observables as well as for flavor and CP violating effective four-fermion operators. We have compared the resulting lower bounds on the Kaluza-Klein (KK) scale in the RS model and a recently proposed model with a metric modified towards the IR brane, which is consistent with oblique parameters without the need for a custodial symmetry. We have randomly generated 40,000 sets of O(1) 5D Yukawa couplings and made a fit of the quark masses and CKM matrix elements in both models. This method allows to identify the percentage of points consistent with a given KK mass, which in turn provides us with a measure for the required fine-tuning. Comparison with current experimental data on Rb, FCNC and CP violating operators exhibits an improved behavior of our model with respect to the RS model. In particular, allowing 10% fine-tuning the combined results point towards upper bounds on the KK gauge boson masses around 3.3 TeV in our model as compared with 13 TeV in the RS model. One reason for this improvement is that fermions in our model are shifted, with respect to fermions in the RS model, towards the UV brane thus decreasing the strength of the modifications of electroweak observables.Comment: 28 pages, 7 figures, 4 table
