Ground water investigation in the southern half of Franklin County, Missouri

Increasing population and industrialization in Franklin County, Missouri, has led to increased demand for water. Much of this demand will be satisfied from ground water resources. Although the general geology of Franklin County has been mentioned in several publications, no detailed study of structure and ground water geology had been done. This thesis consists of study of stratigraphy, lithology, and geologic structure, and analysis of well log data to determine occurrence and availability of ground water, in the southern half of Franklin County. Stratigraphy and lithology is compiled from previous literature, modified to agree with well log data. Structural geology is determined from correlation of well logs and field mapping of the central 38 square miles of the area. Structural data, shown on contour maps of the tops of two major aquifers, the Gasconade and Eminence formations, on isopach map of the Gasconade, and three cross-sections, reveal four major and several minor northeasterly plunging folds. No evidence was found for some possible faults shown on previously published maps. Outcrops examined are indicated on a detailed geologic map of the field area. Relation of number of wells drilled in various formations to expanding population is shown graphically. Depth to static and dynamic water levels, drawdown, and production rates are described for several formations. Specific capacities of the major aquifers are computed. Variations in chemical quality of ground water are illustrated by representative analyses within the area. Appendices list surface elevation, total depth, production and specific capacity of all wells studied --Abstract, page ii

SHORT-RUN AND LONG-RUN DYNAMICS OF TRADE BALANCE: TESTING FOR THE VALIDITY OF MARSHALL-LERNER CONDITION AND J-CURVE HYPOTHESIS IN TURKEY

Growing trade deficit has been one of the major problems of the Turkish economy to date. This study aims to provide empirical insights to policy makers about whether real depreciation or devaluation of Turkish Lira is an effective way of improving the trade deficit. The data employed in this study is quarterly and covers the period of 1987:1 and 2013:3. Recently developed Bounds test to cointegration approach based on Auto Regressive Distributed Lag Model (ARDL) and Error Correction of ARDL model are employed. According to the Bounds testing, at %10 significance level, there is found an evidence for long run relationship among the variables which are trade balance, domestic income, foreign income and real exchange rate. Additionally, estimated long run ARDL model approved the validity of Marshall-Lerner condition in Turkish economy. Finally, short term dynamics obtained from the estimation of error correction model showed that there is no J-Curve effect for the case of Turkey

Blow up of Solutions for a Coupled Kirchhoff-type Equations with Degenerate Damping Terms

In this paper, we investigate a system of coupled Kirchhoff-type equations with degenerate damping terms. We prove a nonexistence of global solutions with positive initial energy. Later, we give some estimates for lower bound of the blow up time

Molecular Detection and Characterization of Goat Isolate of Taenia hydatigena in Turkey

The aim of this study was to provide molecular detection and characterization of the goat isolate of Taenia hydatigena from Ankara province of Turkey. For this purpose, PCR amplification of small subunit ribosomal RNA (rrnS) and partial sequencing of mitochondrial cytochrome c oxidase subunit 1 (mt-CO1) genes were performed in a one-month-old dead goat. According to rrnS-PCR results, parasites were identified as Taenia spp., and partial sequence of mt-CO1 gene was corresponding to T. hydatigena. At the end of the study, we concluded that molecular tools can be used to define species of parasites in cases where the key morphologic features cannot be detected. Nucleotide sequence data of Turkish goat isolate of T. hydatigena was submitted to GenBank for other researchers interested in this subject. By this study, molecular detection and characterization of T. hydatigena was done for the first time in Turkey

Synthesis of potassium–sodium niobate (KNN) from NbO2

KxNa1-xNbO3 (0 0.5) was obtained from 8 M total hydroxide concentration after 6 h of reaction at 200 °C. Rietveld refinement of the XRD data revealed that all samples exhibited the secondary NaNbO3 phase. However, the lowest amount (3.74 vol%) was obtained for 24 h of reaction under 10 M alkaline solution. After 3 h of reaction, dodecahedra shaped hexaniobate phase (KxNa8-xNb6O19.nH2O) was observed. Those structures were, subsequently, replaced by ~3 μm cube shaped KNN crystals, obtained under 10 M reaction in 24 h time period

In vivo performance of antibiotic embedded electrospun PCL membranes for prevention of abdominal adhesions

The aim of this study was to prepare nonwoven materials from poly(-caprolactone) (PCL) and their antibiotic containing forms by electrospinning, so as to prevent postsurgery induced abdominal adhesions in rats. -Caprolactone was first polymerized by ring-opening polymerization, and then it was processed into matrices composed of nanofibers by electrospinning. A model antibiotic (Biteral®) was embedded within a group of PCL membranes. In the rat model, defects on the abdominal walls in the peritoneum were made to induce adhesion. The plain or antibiotic embedded PCL membranes were implanted on the right side of the abdominal wall. No membrane implantation was made on the left side of the abdominal wall that served as control. Macroscopical and histological evaluations showed that using these barriers reduces the extent, type, and tenacity of adhesion. The antibiotic embedded membranes significantly eliminated postsurgery abdominal adhesions, and also improved healing

In vitro transfection of HeLa cells with temperature sensitive polycationic copolymers

Cataloged from PDF version of article.In this study, we investigated different types of polyethyleneimine (PEI) and their block copolymers with N-isopropylacrylamide (NIPA) as temperature-sensitive polycationic non-viral vectors for transfection of HeLa cells in cell culture media. First carboxyl-terminated poly(NIPA) was synthesized and then copolymerized with PEIs branched or linear and with two different molecular weights (2 and 25 kDa). Addition of PEI units to the poly(NIPA) chains increased the LCST values up to body temperature. Zeta potentials of the copolymers were significantly lower than the corresponding PEI homopolymers. A green fluorescent protein expressing plasmid was used as a model. Complexes of this plasmid both with PEIs and their copolymers were formed. The zeta potentials of these complexes were between -3.1 and +21.3. Higher values were observed for the complexes prepared with branched and higher molecular weight PEIs. Copolymerization caused a profound decrease in the positive charges. Particle sizes of the complexes were in the range of 190-1235 nm. Using high polymer/plasmid ratios caused aggregation. The smallest complexes were obtained with the copolymer prepared with branched PEI with 25-kDa molecular weight. Copolymers were able to squeeze plasmid DNA more at the body temperature. Cytotoxicity was observed with PEIs especially with the branched higher molecular weights. Copolymerization reduced the cytotoxicity. The best in vitro DNA uptake efficiency (70%) was achieved with the complex prepared with poly(NIPA)/PEI25B. However, poly(NIPA)/PEI25L was the most successful vector for an effective gene expression without any significant toxicity. © 2004 Elsevier B.V. All rights reserved
