The aim of this work is to realize a new software environment that can be used in the simulation of two dimensional problems as well as in education.
Persistence and periodicity in the precipitation series of Turkey and associations with 500 hPa geopotential heights

Persistence and periodicity in normalised precipitation anomaly series of 91 stations over Turkey were analysed using serial correlation coefficients and power spectra. There were consider- able geographical variations and inter-seasonal contrasts with respect to periodicity and persistence characteristics. Lag-one serial correlation (L-1SC) coefficients for winter series were mostly positive and were significant at the 0.05 level for 31 stations. Annual variations at 17 stations also showed significant positive L-1SC coefficients. In contrast, year-to-year variations in spring series were characterised by negative L-1SC coefficients at most stations (significant at 18). Summer series were characterised by both positive and negative coefficients. Autumn series of most stations were random with regard to serial dependence. For winter series, long cycles of 8.4, 12-12.7, 14, 18 and 21 yr were dominant in the Marmara Transition and the Mediterranean regions, whereas short cycles of 2, 2.1, 3 and 3.2 yr were found for the Black Sea region. Major spectral peaks of most spring series occurred within spectral bands with cycles of around 2, 3, 4 and 5 yr; a 2 yr periodicity was obtained for many stations. Statistically significant negative relationships between precipitation anomalies and 500 hPa geopotential height anomalies in winter and autumn showed an apparent spatial coherence over most of Turkey. Prominent spectral peaks corresponding to about 2 and 3 yr cycles in spring precipitation anomaly series appeared to be associated with similar oscillations in spring geopotential height anom- alies. A cycle of 14 yr was found for winter precipitation and geopotential height anomalies.
One-way coupling of an integrated assessment model and a water resources model: evaluation and implications of future changes over the US Midwest

Abstract. An integrated model is being developed to advance our understanding of the interactions between human activities, terrestrial system and water cycle, and to evaluate how system interactions will be affected by a changing climate at the regional scale. As a first step towards that goal, a global integrated assessment model, which includes a water-demand model driven by socioeconomics at regional and global scales, is coupled in a one-way fashion with a land surface hydrology–routing–water resources management model. To reconcile the scale differences between the models, a spatial and temporal disaggregation approach is developed to downscale the annual regional water demand simulations into a daily time step and subbasin representation. The model demonstrates reasonable ability to represent the historical flow regulation and water supply over the US Midwest (Missouri, Upper Mississippi, and Ohio river basins). Implications for future flow regulation, water supply, and supply deficit are investigated using climate change projections with the B1 and A2 emission scenarios, which affect both natural flow and water demand. Although natural flow is projected to increase under climate change in both the B1 and A2 scenarios, there is larger uncertainty in the changes of the regulated flow. Over the Ohio and Upper Mississippi river basins, changes in flow regulation are driven by the change in natural flow due to the limited storage capacity. However, both changes in flow and demand have effects on the Missouri River Basin summer regulated flow. Changes in demand are driven by socioeconomic factors, energy and food demands, global markets and prices with rainfed crop demand handled directly by the land surface modeling component. Even though most of the changes in supply deficit (unmet demand) and the actual supply (met demand) are driven primarily by the change in natural flow over the entire region, the integrated framework shows that supply deficit over the Missouri River Basin sees an increasing sensitivity to changes in demand in future periods. It further shows that the supply deficit is six times as sensitive as the actual supply to changes in flow and demand. A spatial analysis of the supply deficit demonstrates vulnerabilities of urban areas located along mainstream with limited storage.
FLEXURAL VIBRATION ANALYSIS OF GRAPHENE NANOPLATELETS REINFORCED NANOCOMPOSITE BEAMS

Abstract. Polymer nanocomposites with the addition of a small percentage of graphenes as reinforcement have demonstrated tremendous potential to serve as next generation functional or structural materials due to their combination of high specific surface area, strong nanofiller-matrix adhesion and the outstanding mechanical properties of the sp2 carbon bonding network in graphene. While the majority of the work on graphene based composites has been focused on quantifying their mechanical properties, the vibration characteristics of graphene composites has not yet been investigated. This paper presents an analytical study on the flexural vibration of polymer beams reinforced with uniformly distributed graphene nanoplatelets (GPL). Based on the assumption that each graphene nanoplatelet acts as an effective rectangular solid fiber, the Halpin-Tsai model for fiber-reinforced composites is modified to predict the Young’s modulus of the GPL/epoxy nanocomposites. Governing equations of motion are derived within the framework of linear elastic strain-displacement relationship and Timoshenko beam theory to account for transverse shear strain. The influences of GPL weight fraction, beam slenderness ratio and boundary conditions on the natural frequencies and associated mode shapes are investigated in detail. It is found that adding a very small amount of GPLs into the polymer matrix can effectively lead to a remarkable increase in beam stiffness hence the natural frequencies of the nanocomposite beams, and that the rate of frequency change of the beam is independent of the slenderness ratio.
Randomized observation periods for the compound Poisson risk model: the discounted penalty function

In the framework of collective risk theory, we consider a compound Poisson risk model for the surplus process where the process (and hence ruin) can only be observed at random observation times. For Erlang(n) distributed inter-observation times, explicit expressions for the discounted penalty function at ruin are derived. The resulting model contains both the usual continuous-time and the discrete-time risk model as limiting cases, and can be used as an effective approximation scheme for the latter. Numerical examples are given that illustrate the effect of random observation times on various ruin-related quantities.
On Net External Assets in Developed and Transition Countries

The paper focuses on net external assets (NEA) in developed and transition countries in 1995, 2000, and 2005. The net international investment position is used as the main NEA indicator. In addition, alternative NEA estimates for developed countries are based on the cumulated current account, the cumulated financial and capital accounts, and the net factor income from abroad. The NEA estimates are divided by the gross domestic product (GDP) based on the U.S. dollar exchange rate. We identify the most important net creditors and net debtors, for which we study the average behavior of the real product growth, the unemployment rate, and the inflation rate among developed countries. We conclude that all the given estimates of NEA are good but imperfect.

Preparation of Aluminum-Oleic Acid Nano-Composite for Application to Electrode for Si Solar Cells

Aluminum-oleic acid composite nanoparticles with a mean diameter of 85 nm were successfully prepared by means of a wet chemical process. The Al/oleic acid molar ratio has effects the thickness of the oleic acid layer on Al nanoparticles. Al electrodes can be formed by firing an Al nanoparticle paste film at 600 C, and the firing temperature is about 300 C lower than that required for micrometer-sized Al particles. The electrode formed from commercial Al nanoaparticles is not electrically conducted because of the oxide layer Al nanoparticles; however, the film from the prepared Al nanoparticles for an Al/oleic acid molar ratio of 1 : 0:05 has a minimum specific resistance of 5.6m cm.

Flat-Top and Stacking-Fault-Free GaAs-Related Nanopillars Grown on Si Substrates

The VLS (vapor-liquid-solid) method is one of the promising techniques for growing vertical III-V compound semiconductor nanowires on Si for application to optoelectronic circuits. Heterostructures grown in the axial direction by the VLS method and in the radial direction by the general layer-by-layer growth method make it possible to fabricate complicated and functional three-dimensional structures in a bottom-up manner. We can grow some vertical heterostructure nanopillars with flat tops on Si(111) substrates, and we have obtained core-multishell Ga(In)P/GaAs/GaP nanowires with flat tops and their air-gap structures by using selective wet etching. Simulations indicate that a high-𝑄 factor of over 2000 can be achieved for this air-gap structure. From the GaAs growth experiments, we found that zincblende GaAs without any stacking faults can be grown after the GaP nanowire growth. Pillars containing a quantum dot and without stacking faults can be grown by using this method. We can also obtain flat-top pillars without removing the Au catalysts when using small Au particles.
VARIANCE AS A FACTOR EFFECT IN INTERDISCIPLINARY STUDIES OF AGRICULTURAL SYSTEMS

Studies of interrelationships among factors typically focus on factor effects related to the mean response. In some instances, response variances, as well as, or even rather than, response means, may be affected by the factors under consideration. In this paper, generalizations of Levene's test and the Jackknife test to two-factor experimental designs are studied via simulation studies to assess their ability to identify differences in the variance as an interaction effect or as a factor main effect. These tests are then applied to a particular example where relationships between chile plants and two prominent pests of chile plants -nematodes and yellow nutsedge -are under study. This example illustrates the utility of these tests in studying relationships among factors in agricultural systems.

Low signal-to-noise spectroscopy and surface photometry of two faint galaxies in the field of NGC 7479

We present low signal-to-noise spectroscopy and surface photometry of two small galaxies, detected in the field of the nearby asymmetric barred spiral NGC 7479, near a prolongation of the western arm that forms a faint tail in the disc, and selected as possible companions of this galaxy. The analysis was based on data obtained with the Prime Focus Camera (PFC) at the 0.8 m telescope of McDonald Observatory, and the Low Resolution Spectroscope (LRS) at the 9.2 m Hobby-Eberly Telescope (HET). We determined radial velocities using cross correlation with 15 different templates, and derived integrated magnitudes, colors and brightness profiles for each. The derived radial velocities are around 35 500 $\mathrm{km\,s^{-1}}$ for one galaxy and 38 000 $\mathrm{km\,s^{-1}}$ for the other, which clearly indicates that both are far more distant than the nearby NGC 7479. The absolute magnitudes and diameters of these two background galaxies are typical of normal galaxies, and their colors are similar to other galaxies with similar redshifs. NGC 7479 continues to exist in isolation with no detected companion.
ANTIMICROBIAL SUSCEPTIBILITY OF STRAINS OF COAGULASE-POSITIVE STAPHYLOCOCCUS ISOLATED FROM MASTITIC BOVINE MILK.

A total of 95 coagulase-positive Staphylococcus strains isolated from 635 samples of mastitic milk from 72 dairy farms, were characterized in relation to resistance to 15 antimicrobial drugs. Among the isolates, resistance to sulphonamide was most frequent (80.2%), followed by resistance to ampicillin (78.9%), penicillin (77.8%) and lincomycin (71.5%). Multidrugresistant isolates were extremely common, and almost all isolates also showed resistance to two or more drugs; only one isolate showed resistance to a single drug. These results are probably a consequence of the intensive use of antimicrobial drugs. KEY-WORDS: Coagulase-positive Staphylococcus. Mastitis. Multidrug resistance. Antibiotic.

Phonological priming in spoken word recognition with bisyllabic targets

Four experiments were carried out to examine phonological priming effects on bisyllabic target words. In Experiments 1a and 1b, auditorily presented monosyllabic word and pseudoword primes facilitated lexical decisions to auditorily presented bisyllabic words. This facilitation was found for primes overlapping the targets' initial syllable (e.g., "ver" [worm in French] primed "VERTIGE" [VERTIGO]) and for primes overlapping the targets' final syllable (e.g., ''tige'' [stem] primed "VERTIGE"). Experiment 2 replicated the initial-overlap effect for monosyllabic word primes using a crossmodal (auditory-visual) method; however no facilitation was observed for final-overlap nor for bisyllabic primes (e.g., "verger" [orchard] did not facilitate VERTIGE). In Experiment 3, the initial overlap facilitation effect was replicated in a naming task. These results are interpreted in terms of activation and deactivation of candidates.
Asymmetric melting of a one-third plateau in kagome quantum antiferromagnets

Asymmetric destruction of the one-third magnetization plateau upon heating is found in the spin-$\frac{1}{2}$ kagome Heisenberg antiferromagnets by using the typical pure quantum state approach. The asymmetry originates from a density of states of low-lying excited states of ${N}_{\mathrm{s}}$ spin systems with magnetization $(1/3\ensuremath{-}2/{N}_{\mathrm{s}})$ that is larger than the density of states of low-lying states with magnetization $(1/3+2/{N}_{\mathrm{s}})$. The enhanced specific heat and entropy that reflect the larger density of states in the lower-field side of the plateau are detectable in candidate materials of the kagome antiferromagnets. We discuss how the asymmetry originates from the unprecedented preservation of the ice rule around the plateau.
Thin Cementitious Slabs reinforced with Stainless Steel Fibers

This experimental research by the present authors is to determine the engineering properties such as compressive strength, split-tensile strength, mortar flexural strength and impact energy strength of Fiber Reinforced Cementitious Composite (FRCC) using a new non-corrosive reinforcing material, namely Stainless Steel (SS) fibers. For this purpose, reference specimens (cubes, cylinders and prisms) as well as FRCC slabs of size 250 mm X 250 mm X 25 mm thick were cast. The reinforcing SS fibers of 12.5 mm length with aspect ratio of 28 were used in discontinuous form, and the specimens were cast with varying proportions of SS fibers varying from 0.5% to 2.5% (to volume of specimens). The impact study was conducted on test specimens using a simple free-fall velocity method, using 1 kg steel ball, dropped from a height of 600 mm in a repeated manner and the number of blows received on initial and final cracks (on ultimate failure) were studied. The energy absorbed by the cementitious slabs (test specimens) reinforced with SS fibers has been compared with the control specimens cast with plain cement mortar (without fibers). In general, the results show that there is an increase in the compressive, split-tensile and mortar flexural strength and also the energy absorption capacity of specimens cast with fibrous mortar using SS fibers (0.5-2.5%), when compared to specimens made of plain cement mortar. The initial and final crack widths (during ultimate failure) on the slabs were observed, and the Residual Impact Strength (IRS) Ratio of test and control specimens has been compared. The various applications of using thin, non-corrosive cementitious slabs are brought out in this study.
Handling Uncertainty in Underwater Terrain during Dredging by Using Filled-Matrix Algorithms

This paper brings up a new method to build the underwater terrain which uses filled matrix to represent the terrain so as to resolve the problem of difficult updating the changing underwater terrain in real time during construction. By the filled-matrix, the underwater constructing terrain will be represented realtimely, so as to get constructing condition and avoid superfluous phenomena. Firstly, the paper tells the definition of filled-matrix and how to build the filled-matrix terrain model on the conventional DEM method. Secondly, the authors analyze the underwater terrain uncertainty during constructing and the necessary for resolving the uncertainty. Thirdly, the authors discuss the updating arithmetic for filled-matrix terrain. Finally the paper tells the application of using updating filled-matrix terrain during dredging to get real-time terrain modeling for supervising.
Antiproliferative effects of cembranoid derivatives obtained from Red Sea soft coral Sarcophyton glaucum on human colorectal cancer cell lines

A new source for 2S*,11S*,12R*-isosarcophytoxide (1), along with six known metabolites; 7R,8S-dihydroxydeepoxy-ent-sarcophine (2), sarcophytolol (3), sarcotrocheliol acetate (4), ent-sarcophine (5), guaiacophine (6) and gorgosten-5(E)-3β-ol (7), was identified as Sarcophyton glaucum. The chemical structures were determined based on spectroscopic measurements (NMR, UV, IR and MS). The total extract and isolated compounds were evaluated against four cancer cell lines; HCT116 (human colorectal cancer), HT29 (human colon cancer), CACO-2 (colonic adenocarcinoma) and HepG-2 (human hepatocarcinoma). All tested compounds exhibited cytotoxicity against two cancer cell lines with IC50 in range 8.9–500 µmol/L. Compounds (3) and (4) had significant cytotoxic effects towards HCT116, IC50 = 8.9 ± 0.092 µmol/L and 17.5 ± 0.0. 067 µmol/L, respectively and against HepG-2, IC50 20.0 ± 0.032 µmol/L and 19.9 ± 0.062 µmol/L, respectively. The antiproliferative activities of compounds (3) and (4) can be attributed, at least partly, to their ability to induce cell cycle arrest, particularly in G0/G1 and S phases.
