Sectional Dimensions Identification of Metal Profile by Image Processing

In steel plants, estimation of the production system characteristic is highly critical to adjust the system parameters for best efficiency. Although the system parameters may be tuned very well, due to the machine and human factors involved in the production line some deficiencies may occur in product. It is important to detect such problems as early as possible. Surface defects and dimensional deviations are the most important quality problems. In this study, it is aimed to develop an approach to measure the dimensions of metal profiles by obtaining images of them. This will be of use in detecting the deviations in dimensions. A platform was introduced to simulate the real-time environment and images were taken from the metal profile using 4 laser light sources. The shape of the material is generated by combining the images taken from different cameras. Real dimensions were obtained by using image processing and mathematical conversion operations on the images. The results obtained with small deviations from the real values showed that this method can be applied in a real-time production line.

SOME EULER SPACES OF DIFFERENCE SEQUENCES OF ORDER m

Kizmaz [13] studied the difference sequence spaces ∞（A）, c（A）, and co（A）. Several article dealt with the sets of sequences of m-th order difference of which are bounded, convergent, or convergent to zero. Altay and Basar [5] and Altay, Basar, and Mursaleen [7] introduced the Euler sequence spaces e0^r, ec^r, and e∞^r, respectively. The main purpose of this article is to introduce the spaces e0^r△^（m））, ec^r△^（m））, and e∞^r△^（m））consisting of all sequences whose mth order differences are in the Euler spaces e0^r, ec^r, and e∞^r, respectively. Moreover, the authors give some topological properties and inclusion relations, and determine the α-, β-, and γ-duals of the spaces e0^r△^（m））, ec^r△^（m））, and e∞^r△^（m））, and the Schauder basis of the spaces e0^r△^（m））, ec^r△^（m））. The last section of the article is devoted to the characterization of some matrix mappings on the sequence space ec^r△^（m））.

Age and duration of intra-oceanic arc volcanism built on a suprasubduction zone type oceanic crust in southern Neotethys,SE Anatolia

The southeastern Anatolia comprises numbers of tectono-magmatic]stratJgraphic units such as the metamorphic massifs, the ophiolites, the volcanic arc units and the granitoid rocks. All of them play important role for the late Cretaceous evolution of the southern Neotethys. The spatial and temporal relations of these units suggest the progressive development of coeval magmatism and thrusting during the late Cretaceous northward subduction/accretion. Our new U-Pb zircon data from the rhyolitic rocks of the wide-spread volcanic arc unit show ages of （83.1 ± 2.2）-（74.6 ± 4.4） Ma. Comparison of the ophiolites, the volcanic arc units and the granitoids suggest following late Cretaceous geological evolution. The ophiolites formed in a suprasubduction zone （SSZ） setting as a result of northward intra-oceanic subduction. A wide-spread island-arc tholeiitic volcanic unit developed on the top of the SSZ-type crust during 83 75 Ma. Related to regional plate convergence, northward under-thrusting of SSZ-type ophiolites and volcanic arc units was initiated beneath the Tauride platform （Malatya-Keban） and followed by the intrusion of I-type calc-alkaline volcanic arc granitoids during 84 82 Ma. New U-Pb ages from the arc-related volcanic-sedimentary unit and granitoids indicate that under-thrusting of ophiolites together with the arc-related units beneath the Malatya-Keban platform took place soon after the initiation of the volcanic arc on the top of the SSZ- type crust. Then the arc-related volcanic-sedimentary unit continued its development and lasted at - 75 Ma until the deposition of the late Campanian-Maastrichtian shallow marine limestone. The subduction trench eventually collided with the Bitlis-Pfitfirge massif giving rise to HP-LT meta- morphism of the Bitlis massif. Although the development of the volcanic arc units and the granitoids were coeval at the initial stage of the subduction/accretion both tectono-magmatic units were genetically different from each other.

Machine Learning and Classical Forecasting Methods Based Decision Support Systems for COVID-19

From late 2019 to the present day,the coronavirus outbreak tragically affected the whole world and killed tens of thousands of people.Many countries have taken very stringent measures to alleviate the effects of the coronavirus disease 2019(COVID-19)and are still being implemented.In this study,various machine learning techniques are implemented to predict possible confirmed cases and mortality numbers for the future.According to these models,we have tried to shed light on the future in terms of possible measures to be taken or updating the current measures.Support Vector Machines(SVM),Holt-Winters,Prophet,and Long-Short Term Memory(LSTM)forecasting models are applied to the novel COVID-19 dataset.According to the results,the Prophet model gives the lowest Root Mean Squared Error(RMSE)score compared to the other three models.Besides,according to this model,a projection for the future COVID-19 predictions of Turkey has been drawn and aimed to shape the current measures against the coronavirus.

Lower folate levels in gastric cancer:Is it a cause or a result?

Folate deficiency and its association with cancer have been studied in the literature, but its clinical impact is still unknown. Folate deficiency and its result on gastric cancer is a mysterious part of oncology, with ongoing studies hopefully clarifying its impact on gastric cancer management. Lee et al studied folate deficiency and its impact on staging and clinical results. Here we try to contribute to the field by expressing our own thoughts about the paper.

Thermodynamic Characterization of Planar Shapes and Curves, and the Query of Temperature in Black Holes

The purpose of this research is to characterize shapes in thermodynamic terms, namely, in terms of total energy, dissipative energy, entropy, and temperature. As case studies, polygons and some well-known curves were taken, and they were characterized using physical terms. The relation between entropy and curvature was elucidated, and the black hole surface gravity and temperature were criticized and reinterpreted from this point of view. Particular energy attributions were evaluated by comparing the position of any edge of a polygon (i.e. its angle with the horizontal axis) with a broken crystal surface. Energies of all edges were added up at all positions between 0˚ - 360˚. In regular polygons, the total energy decreases with the increase of the number of edges. Entropy increases in the reverse order, and the increase of the number of edges increases entropy. It implies that the circle has the lowest energy but the highest surface entropy. In curves (circle, sine-curve, spiral, and exponential curve), the total energy, dissipative energy, and entropy all depend on amplitude and also on specific variables. Black hole entropy expressed in terms of the surface area is a configurational entropy and not thermal entropy;therefore, it does not involve a varying temperature term. The surface gravity of a black hole is connected to acceleration and thus to curvature. To relate it with the temperature needs to be reinterpreted, because, surface gravity behaves like an attractive force not exactly like temperature. Hawking radiation is still possible, but the black hole does not get warmer as it evaporates. Material loss from the black hole gets faster as its radius decreases due to the curvature effect, i.e. by a mechanism similar to the Gibbs-Thomson effect.

表现为白塞病样皮损的大疱性坏疽性脓皮病伴发Crohn病

A 47-year-old woman presented with a 2-month history of generalized arthralgia and a 10-day history of oral aphthous ulcers. After hospitalization, papulopustular lesions and perianal ulcerations developed. Pathergy test was positive and ophthalmological examination was normal. The presence of oral aphthous ulcers, genital ulcerations, papulopustular lesions and arthralgia, and the positive pathergy test suggested the diagnosis of disease (BD). In a few days, positive pathergy reactions and papulopustular lesions evolved into bullous lesions, whichwere diagnosed dermatopathologicallyas pyoderma gangrenosum. Two days after the presentation of papulopustular lesions, the patient experienced diarrhoea accompanied by bloody stools and mucus. Histopathological examination of biopsy specimens showed no vasculitis but revealed findings suggestive of Crohn’ s disease. The patient responded well to treatment with systemic steroids and 5-aminosalicylic acid. Our case demonstrates that the differential diagnosis of BD and inflammatory bowel disease may be perplexing and that these two diseases may be closely related.

Time Scale Approach to One Parameter Plane Motion by Complex Numbers

This paper presents building one-parameter motion by complex numbers on a time scale. Firstly, we assumed that E and E′ were moving in a fixed time scale complex plane and {0, e1,e2} and {0', e'1,e'2} ?were their orthonormal frames, respectively. By using complex numbers, we investigated the delta calculus equations of the motion on T. Secondly, we gave the velocities and their union rule on the time scale. Finally, by using the delta-derivative, we got interesting results and theorems for the instantaneous rotation pole and the pole curves (trajectory). In kinematics, investigating one-parameter motion by complex numbers is important for simplifying motion calculation. In this study, our aim is to obtain an equation of motion by using complex numbers on the time scale.

Numerical evaluation of an autofrettaged thick-walled cylinder under dynamically applied axially non-uniform internal service pressure distribution

A dynamical moving pressure structural numerical calculation model using the internal ballistics calculation pressure-time results was constituted and the vicinity of the internal ballistics and quasiinternal ballistics structural model was checked. The Von Mises stresses obtained by the dynamical structural numerical model calculations and the Von Mises stresses calculated from the shot test strain measurements were compared. The difference for the worse case was 20% and for the best case was 0.1%.Furthermore, the model gave better agreement for the higher charge masses. The numerical structural quasi-internal ballistics computation model created was verified for the top charge mass which represents the highest stress condition and used in a gun barrel design.

The accuracy of the method is illustrated by studying the single solitary wave propagation and the interaction of two solitary waves of the modified regularized long wave equation.

Geodynamic significance and genesis of chromitites from the Islahiye ophiolite(Gaziantep,SE Anatolia)as constrained by platinum group element(PGE)compositions and mineral chemistry characteristics

Chromitites associated with intensely altered dunites and harzburgites from fourteen dif ferent localities in the Islahiye ophiolites(SE Anatolia)is reported here for the first time.These chromitites were observed as lenticular and banded bodies with disseminated and massive textures and containing magnesiochromite grains with the following composition:CrO=58.91–59.74 wt%,Al_(2)O_(3)=10.85–11.20 wt%,and TiO=0.09–0.13 wt%.The Mg#[Mg/(Mg+Fe)]values of magnesiochromite from the Islahiye ophiolite range between 0.52 and 0.60 and their Cr#[Cr/(Cr+Al)]values vary from 0.7802 to 0.7844.These contents vary with a constant pattern,coincident with the estimated parental liquids that have originated from the derivative of a single bulk of boninitic magma together with Al,Ti-poor,and Cr-rich initial contents.The chromitites are serpentinised in almost all parts of the study area,and harzburgite and dunite can be observed in different locations.Although the overall composition of platinum group elements(PGE)in most examined chromitites varies between 97 and 191 ppb,three chromitites from the Islahiye region present enrichments in overall PGE(up to 214 ppb).The mineralogical and geochemical features of chromitites from the Islahiye region exhibit a robust similarity to podiform chromitites in the mantle fragment of supra–subduction zone type ophiolitic bodies.The estimated parental magmas of the investigated chromites are consistent with the diff erentiation of arcrelated melts and do not suggest an oceanic spreading centre tectonic environment.The Islahiye chromites are enriched in IPGE(Ir,Os,Ru),with the occasional presence of Ru and Ir and higher Os contents in chromite.Furthermore,we did not find any platinum group minerals(PGM)associated with the serpentine silicate sample matrix,which would have stated a secondary enrichment in PGEs.All chromitites in the investigated region have high Cr and low Ti values,are defined as magnesiochromite and were crystallised from a characteristic boninitic magma.

Asymptotic iteration approach to supersymmetric bistable potentials

We examine quasi exactly solvable bistable potentials and their supersymmetric partners within the framework of the asymptotic iteration method （AIM）. It is shown that the AIM produces excellent approximate spectra and that sometimes it is found to be more useful to use the partner potential for computation. We also discuss the direct application of the AIM to the Fokker-Planck equation.

Regulatory constraint and small business lending:do innovative peer-to-peer lenders have an advantage?

This paper investigates whether innovative Peer-to-Peer lending by FinTechs’has a regulatory advantage over the big banks in respect of small business lending.We do this through the lens of the regulations imposed by the Dodd-Frank Act,using a difference-in-difference methodology.The Act tightened traditional bank credit standards on business loans,especially for small firms.However,the new FinTech lenders were not subject to the same regulatory burden.We find that traditional banks significantly reduced their lending to small businesses,as compared to their FinTech competitors.Our results suggest that while the Dodd-Frank Act constrained lending to small businesses,innovative new lending models gained a regulatory advantage and the Peer-to-Peer lenders capitalized on this.

谷胱甘肽S转移酶M1阳性基因型能否防止原发性开角型青光眼

Purpose: To find out whether the polymorphism at GSTM1, GSTT1 and GSTP1 loci is associated with increased susceptibility to glaucoma. Methods: We genotyped 15 3 primary open angle patients and 159 healthy controls. Genomic DNA from periphe ral blood was examined using polymerase chain reaction and defined for the genet ic polymorphisms of glutathione S-transferase. Results: The frequency of theGST M1 null genotype individuals among the glaucoma patients was significanlty highe r than in controls (54.9 vs 40.9%) with odds ratio of 1.64 (95%CI: 1.10-2.59) . The frequency of the GSTT1 and GSTP1 in both groups were not statistically dif ferent. Conclusion: The present study suggests that the GSTM1 null genotype may be a genetic risk factor for development of primary open angle glaucoma. Further associations studies in other polymorphic genes for xenobiotic-metabolizing en zymes are needed to elucidate the environmental-genetic interaction in the unde rlying cause of primary open angle glaucoma.

Polymorphism of hypoxia-inducible factor-1αgene in pediatric acute respiratory distress syndrome

Objective: To examine if hypoxia-inducible factor-1α (Hif-1α) polymorphisms are associated with pediatric acute respiratory distress syndrome (PARDS). Methods: Twenty two patients with PARDS and 11 non-PARDS controls were examined in pediatric intensive care unit in Cukurova University Balcali Hospital. Blood polymorphism was used to assess the Hif-1α C1772T and G1790A polymorphisms of Hif-1α gene, and differences in genotypes between the 2 groups were compared. Results: Hif-1α C1772T polymorphism was observed only in one case of PARDS group but non-PARDS group didn't show any C1772T polymorphism. Particularly, the difference in number of cases with Hif-1α G1790A polymorphism was not significant between PARDS and non-PARDS groups. In addition, Hif-1α G1790A polymorphism was significantly related to the distribution of lung opacities in children with PARDS (P<0.05). Conclusions: Our results indicate that Hif-1α G1790A polymorphism is related to an increased susceptibility to pulmonary for PARDS children. The detection of G1790A polymorphism could help pediatricians to predict the extensity of PARDS early in lung tissue.

纤维蛋白原和C-反应蛋白水平与先兆子痫严重程度的关系

Objective: The aim of this study was to determine the levels of plasma fibrinogen and C- reactive protein (CRP) in preeclampsia and their association with the severity of the disease. Study design: CRP and plasma levels of fibrinogen were investigated in 26 cases of normal pregnant women, 26 cases with mild preeclampsia and 26 cases with severe preeclampsia in the third trimester of pregnancy. Mean arterial pressure (MAP) was used as an indicator of the severity of the disease. Analysis of variance with the Kruskal-Wallis test was used when three groups were compared. For correlations, Spearman’s rank correlation tests were used. A receiver operating characteristic curve was constructed to evaluate the sensitivity and specificity of CRP. Results: Plasma CRP and fibrinogen levels in mild and severe preeclampsia patients were markedly higher than that of normal third trimester pregnant women. There were significant correlations between MAP and CRP (r = 0.515, p = 0.0001) and MAP and fibrinogen parameters (r = 0.383, p = 0.005) in pregnancies complicated with preeclampsia. Conclusion: We found higher levels of fibrinogen and CRP and presence of good correlation between CRP and MAP in preeclampsia.

Current practice of live donor nephrectomy in Turkey

BACKGROUND Over the last few years,the deceased donor organ donation rate was declined or remained stable,whereas the live donor organ donation rate has increased to compensate for the demand.Minimally invasive techniques for live donor nephrectomy(LDN)have also improved the live donor kidney donation rates.This increase has led to an interest in the surgical procedures used for LDN.AIM To evaluate the LDN techniques performed in Turkey,the structure of surgical teams,and the training received.Additionally,the number of kidney transplantations at different centers,the surgeon experience level,differences in surgical approach during donor surgeries,and outcomes were assessed.METHODS A questionnaire was sent to the Turkish Ministry of Health-accredited transplant centers.It inquired of the number of LDN surgeries,surgical techniques,complications,optimization protocols,the experience of surgeons,and the training.Descriptive statistics were outlined as follows:Discrete numeric variables were expressed as medians(minimum-maximum),while categorical variables were shown as numbers and percentages.As a result of the goodness-of-fit tests,if the significance of the differences between the groups in discrete numerical variables for which the parametric test statistical assumptions were not met,data were analyzed with the Mann Whitney U test and theχ^(2)test.RESULTS The questionnaire was sent to 72 transplant centers,all of which replied.Five centers that reported not performing LDN procedures were excluded.Responses from the remaining 67 centers were analyzed.In 2019,the median number of kidney transplants performed was 45,and the median number of kidney transplants from living donors was 28(1-238).Eleven(16.5%)centers performed 5-10,while 34(50.7%)centers performed more than 100 live donor kidney transplants in 2019.While 19(28.4%)centers performed the LDN procedures using the open technique,48(71.6%)centers implemented minimally invasive techniques.Among the centers preferring minimally invasive techniques for LDN,eight(16.6%)used more than one surgical technique.The most and the least common surgical techniques were transperitoneal laparoscopic(43 centers,89.6%)and single port laparoscopic LDN(1 center,2.1%)techniques,respectively.A positive association was found between the performance of minimally invasive techniques and the case volume of a transplant center,both in the total number and live donor kidney transplants(15 vs 55,P=0.001 and 9 vs 42,P≤0001 respectively).The most frequently reported complication was postoperative atelectasis(n=33,49.2%).There was no difference between the techniques concerning complications except for the chyle leak.CONCLUSION Turkish transplant centers performed LDN surgeries successfully through various techniques.Centers implementing minimally invasive techniques had a relatively higher number of live donor kidney transplants in 2019.

Thermal Properties of Some Turkish Peloids and Clay Minerals for Their Use in Pelotherapy

The thermal properties such as specific heat capacity and heat dissipation of peloids play an important role in therapeutic applications. Therefore, these properties were determined on the peloids samples taken from spas where peloid applications are used in Turkey. In addition, some pure clay minerals were investigated to determine their suitability as possible constituents of therapeutic peloids and to make recommendations for preparing the most usable peloids for thermal therapy. For this aim, the mineralogical and thermal properties of samples were investigated using X-ray diffraction (XRD) and Differential Scanning Calorimeter (DSC). The mineralogical compositions of the peloid samples are not homogenous, and their clay mineral content is approximately 60%, and the most abundant clay mineral is calcium montmorillonite. The cooling time of peloids are between 20 and 25 minutes, which is suitable for therapy and thus these peloids are suitable for using in health problems requiring heat treatment. The samples have favorable heat dissipation capacity and partially cooling kinetics. Specific heat capacity of the peloid samples is partially appropriate for heat therapy and these values range from 0.60 to 1.41 J/g·°C, and partially high in peloids with high smectite content. The pure sepiolite samples have higher heat dissipation properties than those of other clay minerals especially illites and kaolinites. Ca-montmorillonite and kaolinite have the lowest specific heat values while sepiolite samples have higher values. Sepiolite and partly Na-Ca-montmorillonite are more appropriate than the other studied clay minerals as a peloid constituent especially for therapy of musculoskeletal pain.
