Hydrologic modeling of the loess bluff in Dunaujvaros, Hungary

The western shoreline of the Danube from Erd to Mohacs consists of loess bluffs up to 50 m high. These bluffs can be susceptible to landslides when groundwater conditions weaken the supporting loess. Often this will occur during periods of high rainfall, however morphological, geological and other factors are also important in triggering these movements. Changes in pore water pressures related to precipitation, confined water levels driven by remote catchments, and river level fluctuations are widely recognized as important factors controlling the loess bank stability. This work aims to determine the interaction of rainfall, river level, drainage and local pumping on the pore pressure regime and stability of the bluffs. As a first step, a realistic 2-dimensional infiltration and groundwater model was built that reflects the influence of river levels, rainfall patterns, and local pumping. Based on model results, initial and boundary conditions have a strong influence on seasonal pore pressures. Further stu.
Promoting development with low achievement grouping students in Taiwan

It is hypothesized that students who are categorized in the C-level (low level) Achievement Grouping (AG) in English instruction classes did not necessarily performed at their peak potential in English language competence. Furthermore, it is assumed that the underlying concepts behind the low achievement levels may lies in two assumptions. First, Brophy (2004) addressed the situation with four categories of students based upon how expectancy-related motivational problems might cause students to develop low expectations for themselves. Second, the concept involving the use of AG, might have cause some of the more capable students to lower their achievement levels in English. In response, an action research was accomplished using a Cooperative Task-Based Learning (CTBL) model, based on the concept of learning motivation for students with low achievement levels in an attempt to enhance the students’ English competencies. To evaluate the effectiveness of such teaching methodology, data were collected in the form of interview accounts, self-reflective logs, field notes, observations, and students’ work sheets. Results show that numerous positive outcomes from both the teachers’ and the students’ perspectives were noted from the use of the CTBL. In addition, results also show that cooperative group work has proven to be an effective learning strategy. Lastly, useful implications based on the findings were given to shed light on issues regarding the positive effects of skilled-based curriculum designs.
Research and application of a combined model based on variable 1 weight for short term wind speed forecasting

17 Wind speed forecasting plays a prominent part in the operation of wind power 18 plants and power systems. However, it is often difficult to obtain satisfactory prediction 19 results because wind speed data comprise random nonlinear series. Current some 20 statistical models are not proficient in predicting nonlinear time series, whereas 21 artificial intelligence models often fall into local optima. For these reasons, a novel 22 combined forecasting model, which combines hybrid models based on decomposed 23 methods and optimization algorithms, is successfully developed with variable 24 weighting combination theory for multi-step wind speed forecasting. In this model, 25 three different hybrid models are proposed and to further improve the forecasting 26 performance, a modified support vector regression is used to integrate all the results 27 obtained by each hybrid model and obtain the final forecasting results. To verify the 28 forecasting effectiveness of the proposed forecasting model, 10-min wind speed series 29 from Penglai, China, are used as case studies. The experimental results indicate that the 30 developed combined model not only outperforms other benchmark models but also can 31 be satisfactorily used for planning for smart grids.
Locally Weighted Classifiers for Detection of Neighbour Discovery Protocol DDoS and Replayed Attacks

The Internet of Thing (IoT) requires more IP addresses than Internet Protocol version 4 can offer. To solve this problem, Internet Protocol version 6 was developed to expand the availability of address spaces. Moreover, it supports hierarchical address allocation methods, which can facilitate route aggregation, thus limiting expansion of routing tables. An important feature of the Internet Protocol version 6 (IPv6) suites is the Neighbour Discovery Protocol (NDP), which is geared towards substitution of the Address Resolution Protocol in router discovery, and function redirection in Internet Protocol version 4. However, NDP is vulnerable to Denial of Service (DoS) attacks. In this contribution, we present a novel detection method for Distributed Denial of Service (DDoS) attacks, launched using NDP in IPv6. The proposed system uses flow-based network representation, instead of packet-based. It exploits the advantages of Locally Weighted Learning techniques, with three different machine learning models as its base learners. Simulation studies demonstrate that the intrusion detection method does not suffer from overfitting issues, offers lower computation costs and complexity, while exhibiting high accuracy rates. In summary, the proposed system uses 6 features, extracted from our bespoke dataset and is capable of detecting DDoS attacks with 99% accuracy and replayed attacks with an accuracy of 91.17%, offering a marked improvement in detection performance over state-of-the-art approaches.
Magnetostrictive helical array transducer for inspecting spiral welded pipes using flexural guided waves

A wavefront analysis indicates that a flexural wave propagates at a helix angle with respect to the pipe axis. The expression for calculation of the helix angle for each flexural mode is given, and the helix angle dispersion curves for flexural modes are calculated. According to the new understanding of flexural guided waves, a magnetostrictive helical array transducer (MHAT) is proposed for selectively exciting a single predominant flexural torsional guided wave in a pipe and inspecting spiral welded pipes using flexural waves. A MHAT contains a pre-magnetized magnetostrictive patch that is helically coupled with the outer surface of a pipe, and an array of novel compound comb coils that are wrapped around the helical magnetostrictive patch. The proposed wideband MHAT possesses the direction control ability. A verification experiment indicates that flexural torsional mode T(3,1) at center frequency f=64kHz is effectively actuated by a MHAT with 13-degree helix angle. A 20-degree MHAT is adopted to inspec.
Relationship of Normal CDF1 Mouse Leukocyte Kinetics to Growth Characteristics of Leukemia L1210

Leukocyte kinetics were studied in the CDF1 mouse using liquid scintillation and radioautographic technics. Although the latter method provides more detailed information, the former technic is readily adaptable -to experimental manipula tions. The kinetics of mouse leukocytes are different from those in man. Either marrow storage and transit times are different or the generation times of mouse marrow progenitor cells is shorter. Data presented in this study and those available in the literature support the latter concept. The selective thera peutic advantage of the mouse marrow cells is probably related to the presence of nonproliferating cells inaccessible to chemo therapy as reported in the literature. Knowledge of nor and tumor cell kinetics is if to
Small-Amplitude Convection in a Conditionally Unstable Stratification*

The properties of small-amplitude convection in the conditionally unstable stratification of the atmosphere which have been studied by Kuo (1961, 1965) are re-examined by the use of the finite difference method which implicitly introduces the condition for the continuity of the horizontal gradient of temperature at the internal boundary between an ascending region and a descending region. This condition, which was not used by Kuo, is required for the finiteness of the horizontal eddy thermal diffusivity term which is assumed to be of the Fickian type. It is shown that when the horizontal size of a convective cell as well as some physical parameters are specified, the horizontal size of an ascending area is uniquely determined. This property is markedly contrasted with the property of convection for the non-viscous case (Haque, 1952; Lilly, 1960) where the size of an ascending area is not uniquely determined. The use of the finite difference method enables us to discuss the properties of unstable convection. The dependencies of the growth rate and other properties of convection on physical parameters are studied. The properties of convection is also studied as an initial value problem. Furthermore, it is shown that this approach is very useful to obtain an eigensolution, particularly when the separation of variables with respect to the horizontal and vertical coordinates is impossible.
Phase relations of potassium-bearing clinopyroxene in the system CaMgSi 2 O 6 -KAlSi 2 O 6 at 7 GPa

The pseudo-binary system CaMgSi 2 O 6 -KAl-Si 2 O 6 , modeling the potassium-bearing clinopyroxene ( KCpx ) solid solution, has been studied at 7 GPa and 1,100–1,650 (cid:2) C. The KCpx is a liquidus phase of the system up to 60 mol% of KAlSi 2 O 6 . At higher content of KAlSi 2 O 6 in the system, grossular-rich garnet be-comes a liquidus phase. Above 75 mol% of KAlSi 2 O 6 in the system, KCpx is unstable at the solidus as well, and garnet coexists with kalsilite, Si-wadeite and kyanite. No coexistence of KCpx with kyanite was observed. Above the solidus, KAlSi 2 O 6 content of the KCpx coexisting with melt increases with decreasing temperature. Near the solidus of the system (about 1,250 (cid:2) C) KCpx contains up to 5.6 wt% of K 2 O, i.e. about 22–26 mol% of KAlSi 2 O 6 . Such high concentration of potassium in KCpx is presumably the maximal content of KAlSi 2 O 6 in the Fe-free clinopyroxene at 7 GPa. In addition to the major substitution Mg M1 Ca M2 , Al M1 K M2 , the KCpx solid solution contains Ca-Eskola and only minor Ca-Tschermack components. Our experimental results indicate that the natural assemblage KCpx+ grossular rich garnet might be a product of crystallization of the ultra-potassic SiO 2 -rich alumino-silicate mantle melts (>200 km).
In situ ambient pressure XPS observation of surface chemistry and electronic structure of  -Fe 2 O 3 and  -Fe 2 O

94720, USA Abstract Fundamental understanding of charge transfer reaction is essential for the surface and interface engineering of transition metal oxides. In this study the chemical reactivity towards oxygen and hydrogen (13 Pa) under applied thermal conditions (423 - 673 K), of two polymorphic forms of Fe 2 O 3 nanoparticles (γ -Fe 2 O 3 and α -Fe 2 O 3 ) are investigated with the combination of in situ ambient pressure X-ray photoelectron spectroscopy (AP-XPS) and near edge X-ray absorption fine structure spectroscopy (AP-NEXAFS). Our data show that the reactivity of these two polymorphs has a similar character based on the contribution of oxygen vacancy defect states and related material non-stoichiometry. Their exposure to hydrogen at increased temperature results in both cases in the surface reduction. However, Fe 2 O 3 exhibits more covalent character and undergoes the reduction preferentially with a contribution of metallic Fe 0 than Fe 2+ , in contrast to α -Fe 2 O 3 . Further, upon introduction of oxygen at low temperature of 423 K, rapid re-oxidation process takes place at the Fe 2 O 3 nanoparticles surface. Prepared γ -Fe 2 O 3 and α -Fe 2 O 3 nanostructures exhibit in general high n-type and p-type sensor response towards hydrogen, respectively, in a wide concentrations range.

International Marketing Title: If and how environmental friendliness be a profitable marketing strategy in the current recession? A comparative study on managements’ perspectives at two food retailers in Sweden. Problem: During the current recession, consumers are not as much willing to pay more for green but expensive products as were in the past. However, despite this changing consumer attitude, food retailers in Sweden claim their marketing strategy as environmentally friendly. When maximizing profits is considered major corporate goal of every business, investigating the managements’ point of view on environmental friendliness as profitable marketing strategy in the recession period becomes an interesting topic for research. Purpose: The objective of this paper is to get insight on management’s perspectives from large-scale food retailers in Sweden on their choice of environmental friendliness as marketing strategy with respect to profitability in the current recession. Method: This qualitative study utilizes realist approach to research and exploratory research method. Through literature review, a conceptual model was developed for study. Primary data comes from interviews whereas secondary data from websites and annual reports of the companies. Conclusion: The green marketing strategy is profitable even in recession as it is a great source of competitive advantage and numerous profitable opportunities. This commitment to environment in hard times yields favorable reputation and helps companies in developing new products; finding new markets and suppliers; expanding customer-base; improving processes and stores; enhancing efficiency; etc.
EXPERIMENTS AND SIMULATION OF FLEXURAL-SHEAR DOMINATED RC BRIDGE PIERS UNDER REVERSED CYCLIC LOADING

In recent earthquakes, a large number of reinforced concrete (RC) bridges were severely damaged as a result of a mixed flexural-shear failure of the bridge piers. An integrated experiment and analysis research program is undertaken in this paper to study the seismic performance of flexural-shear dominated RC bridge piers. In the first part, cyclic loading tests on 6 RC bridge piers were carried out experimentally. The damage states, ductility, and energy dissipation of the piers were compared with each other. In the second part, modeling approaches describing the hysteretic response of the piers were investigated by using ANSYS software. A set of model with different parameters was selected and evaluated through comparison with experimental results. Then, a modified analysis model is presented and the accuracy of the model has been verified by comparing the calculated results with experimental ones.

THE IMPACT OF FOREIGN DIRECT INVESTMENT ON EXPORT OF HIGH-TECHNOLOGY PRODUCTS: THE ROLE OF FINANCIAL DEVELOPMENT AND REGULATORY QUALITY *

: This study aims to reveal whether financial development and regulatory efficiency have a noteworthy role in developing countries ‘relationship between foreign direct investment and export of high-tech products. Rich panel data from 70 developing countries for the period 2002-2015 are used in the analysis to examine the relevant relationship. The Generalized Moments Method (GMM) is utilized in the study, since it allows to control the endogeneity relationship between variables. Findings shows that financial development and regulatory quality level affect the contribution of FDI on exports of high-tech products in developing countries. According to results, in countries where regulatory quality and financial development level are higher, FDI may contributes positively to export of high technology products. However, it couldn’t be found any significant relationship for countries which have less regulatory quality and financial development level.
High effectiveness of platinum complexes with adamantylamine in overcoming resistance to cisplatin and suppressing proliferation of ovarian cancer cells in vitro PhD Thesis

[(OC-6-43)-bis(acetato)(1-adamantylamine)amminedichloroplatinum(IV)], coded as LA-12, is an octahedral platinum(IV) complex containing a bulky hydrophobic ligand – adamantylamine. The use of bulky hydrophobic amines as non-leaving ligands, may increase uptake of the compound by the cancer cells. Therefore, the effects of LA-12 on sensitive (A2780) and cisplatin resistant (A2780cis) ovarian cancer cell lines were investigated and compared to those of cisplatin. IC50 and IC90 concentrations of LA-12 were 6(A2780) or 18-fold (A2780cis) lower than those for cisplatin (MTT assay). Equitoxic concentrations (IC50 or IC90) of both compounds caused a significant and similar timeand dose-dependent inhibition of cell proliferation and an increase in the number of floating cells which corresponded to the decrease of total cell viability. A different type and dynamics of cell cycle perturbation after cisplatin and LA-12 treatment were detected. Exposure to LA-12 resulted in transient accumulation of A2780 and A2780cis cells in S phase, while cisplatin caused G2/M arrest in sensitive and S phase arrest in resistant cells. A relatively low rate of apoptosis after exposure to IC50 or IC90 of both complexes was observed, markedly higher in resistant A2780cis cells. Western blot analysis indicated a concentration-dependent p53 level increase in both lines (higher after cisplatin treatment). PARP cleavage was observed only in A2780cis cells. In conclusion, LA-12 was found to be significantly more efficient than cisplatin, and it was able to overcome the acquired cisplatin resistance (showing resistance factor 2.84-fold lower than those for cisplatin). In spite of the low rate of apoptosis, LA-12 caused increase of p53 level and cell cycle perturbations in the ovarian cancer cell lines studied. # 2004 Elsevier Inc. All rights reserved.

Condom use by South African construction workers

Abstract Consistent and proper condom use is pivotal in preventing HIV infection. HIV prevalence in South Africa is among the highest in the world, with the construction industry especially affected, yet little is known about condom use by construction workers and the determinants thereof. Data were gathered from 512 site-based workers in the Western Cape. A theoretical model explaining condom use as a function of demographic factors, HIV knowledge, substance usage and risky sexual behaviour (excluding condom use) was proposed and tested using regression and structural equations modelling. The findings indicated that age, gender and level of education were indirect determinants of condom use, with higher levels of education predicting better AIDS-related knowledge. Higher levels of risky sexual behaviour were associated with more frequent use of condoms, suggesting greater awareness of risk. Condom use was adversely affected by greater alcohol and drug use, probably as a result of diminished capacity to assess risk. Finally, lower and not higher levels of AIDS-related knowledge were associated with better condom use, suggesting that improved knowledge of HIV transmission may work contrary to safe sex practice if it lulls the person into a false sense of confidence. Recommendations for targeted workplace interventions are proposed.
Becoming a Healthy Therapist: Influences of the Training Program Culture

Psychotherapists experience a variety of stressors, and many report mental health problems and burnout. However, most psychologists are satisfied with their careers. Therapists-in-training experience similar challenges, and must also survive the demands of graduate school, yet the number of applicants to Canadian psychology programs continues to rise. What attracts these individuals to practice psychology in spite of the negative effects of therapy work? How do they overcome challenges and remain healthy during training? My aim in this study was to gain insight into the experiences of novice therapists. I wanted to explore their perceptions of health, and identify influences that contributed to and hindered their well-being. Interviews with six trainees were conducted, and what resulted was an ethnographic thesis focused on the experiences of novices in the context of training. Participants provided deep, detailed descriptions of how their beliefs, expectations, and well-being were impacted by the culture of training programs.
Al-rich Fe0.85 Al0.15 (100), (110) and (111) surface structures

Based on previous photoemission ﬁndings, the inﬂuence of newly observed aluminum surface segregation at the low (110), (100) and (111) index surfaces of the A 2 body-centered Fe 0 . 85 Al 0 . 15 random alloy is explored. Scanning Tun-neling Microscopy, Low-Energy Electron Diﬀraction and Grazing-Incidence X-Ray Diﬀraction are combined to explore surface structures and topogra-phies. The formation of a surface composition close to the B 2 Fe 0 . 5 Al 0 . 5 occurs with the appearance of (i) a long-range pseudo-hexagonal incommensurate superstructure with a periodicity of ∼ 18 ˚A on the (110) surface, (ii) a (1 × 1) termination on the (100) surface and (iii) a intense vicinal faceting of the (111) surface in the form of triangular pits.
