Soil Properties of the Quarry Areas in Suleymanpasa-Tekirdag

The purpose of this study was to determine soil properties of the stone quarry area located in Suleymanpasa district of Tekirdag province of Turkey, and to assess the suitability of these areas for agriculture. The study also explored the effects of the quarries on the environment and examined the legal regulations and environmental relations. For this purpose the Great Soil Groups Map and Land Use Capability Map of the region were analyzed and identified the borders of the quarries on these maps. The borders of the quarries were superimposed on these maps using the software ArcGIS. The research results indicated that the whole area of the quarries covers class II and class III lands and the quarries operate in Grumusol and Brown Forest Soils. The size of agricultural land removed by stripping operations of the quarries was about 206 hectares and the amount of soil lost was estimated to be 4,622,000 tons based on average soil depth and bulk density.Namik Kemal University Scientific Research Projects Unit (BAP) [NKUBAP.03, YL.17.087]This work has been made from master's thesis that was supported by Namik Kemal University Scientific Research Projects Unit (BAP) as project NKUBAP.03.YL.17.087

Paleocene orthophragminids from the Lakadong Limestone, Mawmluh Quarry section, Meghalaya (Shillong, NE India). Implications for the regional geology and paleobiogeography

The late Paleocene orthophragminids, hitherto poorly known from the Himalayan foreland basins, are studied from the Lakadong Limestone in Meghalaya, northeastern India, in order to establish a systematic, biostratigraphic, and paleobiogeographical framework for them in the eastern Tethys. In the Mawmluh Quarry section (MQS) on the Shillong Plateau, to the southeast of Tibet, orthophragminids are associated with typical Paleocene orbitoidiform taxa endemic to the Indian subcontinent, i.e., Lakadongia Matsumaru & Jauhri ( D Setia Ferràndez-Cañadell) and Orbitosiphon Rao, and various species of alveolinids, miscellaneids, and rotaliids, characterizing the Shallow Benthic Zones (SBZ) 3 and 4. The orthophragminids belong to two lineages of the genus Orbitoclypeus Silvestri: O. schopeni (Checchia-Rispoli) and O. multiplicatus (Gümbel), both well known from the peri-Mediterranean region and Europe (western Tethys). The latter species is identified here for the first time from the eastern Tethys. Previous records of the genus Discocyclina Gümbel from the Lakadong Limestone actually correspond to misidentified Orbitoclypeus; this implies that the late Paleocene orthophragminid assemblages from Meghalaya and eastern Tethys were less diverse than in the western Tethys. The lineage of Orbitoclypeus schopeni in the lower part of the Lakadong Limestone (SBZ 3) is identified as O. schopeni cf. ramaraoi based on the morphometry of a few specimens, whereas in the upper part (SBZ 4) it corresponds to a transitional development stage between O. schopeni ramaraoi and O. schopeni neumannae (with average Dmeanvalues ranging between 192 and 199 μ m). The embryon diameters of O. multiplicatus, recorded only in SBZ 4, range between 300 and 319 μ m on average, corresponding to transitional development stages of O. multiplicatus haymanaensis and O. multiplicatus multiplicatus. Our data, along with a review of previous Paleocene and Eocene records from India and Pakistan, suggest that Orbitoclypeus is the only orthophragminid in the Paleocene of the eastern Tethys, whereas Discocyclina first appears in early Eocene times, being mainly represented by endemic taxa confined to the Indian subcontinent. Facies change in the MQS from a marine to continental setting within SBZ 4 corresponds to the oldest record from the Indian plate in the Paleogene, which may be linked to the flexural uplift of the passive margin of the Indian plate, marking the onset of the collision of the Indian and Eurasian plates

A Portable Multispectral Vein Imaging System

Phlebotomy may cause unnecessary injuries to a patient whose veins are not easily visible to a healthcare professional. To mitigate this problem we designed a new system to image subcutaneous veins. Multispectral images were obtained using a microprocessor, an IR (infrared) camera, different wavelengths of NIR (near-infrared) sources, and an IR band-pass filter. Raw vein images were enhanced, colored, and displayed on a monitor using an easy-to-use interface. The mean dice similarity index (DSI) between the vein border specified by a doctor on the raw images manually and the automated segmented by the proposed system is determined as 0.92 ± 2.1 for 20 subjects. Also, the average peak signal-to-noise ratio (PSNR) obtained a high value of 68.37 ± 1.56 from the enhanced image. Phlebotomists can easily observe the subcutaneous veins in real-time with the three different options using the proposed device. As a result, this study advances the vein imaging field which has the potential to reduce injury to the patient during venipuncture

Length–Weight, Length–Length Relationships and Condition Factor of Chondrostoma regium (Heckel, 1843) and Barbus lacerta, Heckel, 1843 From Karasu River (East Anatolia, Turkey)

Length–weight, length–length relationships and condition factors were estimated for two fish species (Chondrostoma regium, Barbus lacerta) caught between October 2014 and September 2015 in the 14 distinct locations of Karasu River, East Anatolia, Turkey. Minimum and maximum total length and weight were observed at 7.5 to 31.0 cm and from 5.7 to 280 g for C. regium, 7.0 to 24.0 cm and from 4.0-211 g for B. lacerta. The b values determined as 2.77 for Chondrostoma regium; 3.10 for Barbus lacerta. The types of growth were found negative allometric for C. regium and isometric growth for B. lacerta. The length-length relations between total, fork, and standard lengths for the two fish species were highly significant. The relative condition factor values were found to 1.102±0.013 for C. regium; 1.176±0.019 for B. lacerta. This study submits for the first time LWR, LLR and condition factor of two species in the Karasu River

Effects of ethylenediaminetetraacetic acid and sodium hypochlorite on the bond strength of bonding agents to pulp chamber lateral walls

AbstractBackground/purposeThe purposes of this in vitro study were to determine the microtensile bond strengths of four different dentin adhesive materials placed in pulp chamber walls, and to test the effects of 5% sodium hypochlorite (NaOCl) and 17% ethylenediaminetetraacetic acid (EDTA) pretreatments on resin dentin bond strengths.Materials and methodsRecently extracted human third molars were selected. The teeth were divided into four groups. Specimens in each group were treated as follows: irrigated with distilled water; irrigated with EDTA for 5 minutes; irrigated with sodium hypochlorite for 5 minutes; and irrigated with EDTA for 5 minutes followed by NaOCl for 5 minutes. Treated specimens were dried, bonded with a total-etching adhesive, two self-etching adhesives, or a one-bottle self-etching adhesive system. After the bonding procedure and composite restoration, teeth were sectioned, and 15 dentin sticks were obtained. Microtensile testing was performed, and scanning electron micrographs were taken of each irrigated group.ResultsIn the control group, the one-bottle self-etching adhesive system showed statistically higher bond strength values. EDTA irrigation did not affect the bond strength except for the total-etching adhesive. NaOCl significantly reduced the bond strengths of all adhesives. The EDTA and NaOCl combination did not show a statistically significant reduction in bond strengths of the adhesives to pulpal dentin.ConclusionThere was a reduction in bond strengths of all adhesive systems used to test pulp chamber lateral walls after endodontic irrigation solutions were used

New Bryophyte Records from Turkey and Southwest Asia

Five bryophytes collected during bryological forays to the Ordu and Burdur regions of Turkey were of particular interest. Among them, Orthotrichum hookeri, Plagiothecium neckeroideum and Thamnobryum neckeroides were found to be new to Turkey. Orthotrichum hookeri and Plagiothecium neckeroideum are also new to Southwest Asia. Descriptions, illustrations, ecology, geographic distribution and comparisons with morphologically similar taxa are presented. Two species, Hookeria acutifolia and Orthotrichum sordidum, were recorded only for the second time in Turkey

A case of urachal malacoplakia that seems like urachal cancer

Background: Urachal masses observed in adults should be considered malignant unless they are confuted. It is very difficult to differentiate between malignant or benign lesions, including especially calcified foci and solid areas. Case Report: Our case was a 63-year-old male patient who was diagnosed as Behçet’s Disease 26 years ago. Upon clinical examination, he was also diagnosed with adenocarcinoma of prostate. He was examined by computerized tomography to define the stage of prostatic adenocarcinoma. The existence of a hypodense multiseptated cystic lesion with irregular margins and solid areas located between anterosuperior of bladder and umbilicus was reported. Hence, the lesion was evaluated as urachal carcinoma and locally advanced prostate cancer by the urooncology council. Resection of the mass, partial cystectomy and pelvic lymphadenectomy were performed as one of the surgical approach options in urachal carcinoma. After pathological examination, the mass was diagnosed as malakoplakia and metastasis of prostate adenocarcinoma was also detected in the right obdurator lymph nodule. In the literature, case reports of urachal malakoplakia are extremely rare. It is also interesting to note the absence of specific clinical symptoms for the urachal mass and the existence of concomitant adenocarcinoma in our case. Conclusion: Malakoplakia can only be diagnosed by pathological examination. Particularly, urachal malakoplakia should also be taken into consideration in the differential diagnosis of lesions which include solid areas and are located in the urachus.

Elastic properties of the aorta and factors affecting aortic stiffness in patients with

Objectives: In this study, we evaluated aortic stiffnessand echocardiographic and laboratory factors affectingaortic stiffness in patients with metabolic syndrome(MetS).Materials and methods: Forty-six patients (25 male,mean age 47.3±6.5 years) with the diagnosis of MetS accordingto the Adult Treatment Panel III Final Report criteriawere included. Forty-four age and gender matchedhealthy subjects (18 male, mean age 46.0±6.1 years)were recruited as the control group. Aortic strain, distensibilityand stiffness index were calculated by M-modeechocardiography and diastolic parameters were measured.Results: Left ventricular mass index (LVMI), decelerationtime (DT), isovolumic relaxation time (IVRT) wereincreased and mitral E/A ratio was decreased in patientswith MetS compared to controls. In the MetS patients,aortic distensibility was significantly decreased (10.4±3.5cm2.dyn-1.10-6 vs. 12.7±3.4 cm2.dyn-1.10-6, p=0.002),and ASI was significantly increased (6.5±2.0 vs. 3.2±0.8,p<0.001). ASI was positively correlated with triglycerides,fasting glucose, uric acid, hsCRP, LVMI, DT, IVRT andsystolic blood pressure level, and was negatively correlatedwith HDL-cholesterol and mitral E/A ratio. In regressionanalysis, hsCRP (p=0.05) and systolic blood pressurelevel (p<0.001) were independent predictors of ASI.Conclusions: ASI is increased in patients with MetS. Inthese patients; decrease in aortic elasticity properties wasassociated with left ventricular diastolic dysfunction. Highsystolic pressure and hsCRP levels were found to be independentpredictors of ASI.Key words: Metabolic syndrome, Echocardiography,elastic properties of aorta, hsCR
