Multiple Stress Creep Recovery (MSCR) Test for Determination of Waste Engine Oil Modified Asphalt Binder as Pavement Material

Engineers have been using modified binders to improve the quality of flexible pavements. The use of waste material is one of the solutions taken in this direction. It is for this ground that the studies emphasis on the evaluation of waste engine oil as a modifier for asphalt binder as a pavement material. In the study uses four samples extracted from 80/100 penetration grade bitumen. From four sample first sample was checked for weather requirements of asphalt binder meet or not and the three were modified with different content of engine oil (3,6 and 9%). The behaviors of both unmodified and modified binder were checked for rheological properties. Dynamic shear rheometer (DSR) was used to determine high temperature performance grade (PG) and multiple stress creep recovery tests to determine rutting resistance properties of the binder. PG analysis indicates that both aged and un-aged 3% and 6% modified binder have similar higher PG grade with the unmodified one and 9% modified to have lower PG vale. Jnr3.2 value of modified asphalt binder is lower than unmodified binder indicating that modification had improved the rutting resistance and design traffic load (ESALS). The study shows that it is possible to use waste engine oil-modified binder as a pavement material.

Numerical Study and Experimental Validation of the Thermal Performance for a Parallel Channel Optical Module

To meet the insatiable demand for data bandwidth in VSR (very short reach up to 300m) applications including server and routers, parallel optical interconnection offers a promising solution in terms of performance and cost effectiveness. A 12-channel pluggable paralle optical transmitter module has been developed to achieve a data rate of 2.5 Gb/s per channel. To maintain the robustness of the optical signal integrity under different environmental conditions, the thermal management is crucial. In this paper the thermal performance evaluation of the optical module was carried out through both numerical simulation and experimental verification. The optical module mainly consists of a VCSEL (vertical cavity surface emitting laser) array, a driver IC and a heat sink. Three types of heat sinks were integrated into the transmitter module separately. The thermal environments used for this evaluation include the normal and high ambient temperature, and both still-air and forced-air conditions. The ambient temperature and the wind speed were controlled by using a Wind Tunnel. The simulation was performed by using a CFD (computational fluid dynamics) program. In all the three modules, the simulation and experimental results of the junction temperature have shown good agreements. For Module 1 under the high ambient temperature, a forced-air condition was required to keep the junction temperature below 70°C. For Module 2 and Module 3, the junction temperature can be controlled below 70°C even under the high ambient temperature without using a fan. © 2003 ASME

High Early Strength Fly Ash Concrete for Precast/Prestressed Products

72 Presents field applied research to report the advantages of using a high quality ASTM C-618 Class C fly ash on water demand, workability and compressive strength of concrete. The research was performed at two precast/prestressed concrete plants to identify optimum mixture proportions for production of high early strength concrete with high fly ash contents. Tests were carried out on nominal 5000 psi (34 MPa) concrete utilizing fly ash produced at Wisconsin Electric Power Company's Pleasant Prairie Power Plant. Fly ash replacement improved workability, decreased water demand, and increased strength while maintaining the high early strength requirements of precast/prestressed concrete operations.
Wetland Monitoring, Characterization and Modelling under Changing Climate in the Canadian Subarctic

Subarctic wetlands that exist as bogs, fens, swamps, marshes and shallow water, comprise 3% of the Canadian landscape. They have been recognized as important ecotones between the arctic tundra and boreal forest. Recently, there has been growing research interest in the hydrological characteristics of arctic and subarctic wetland systems in the need for more efficiently conserving wetlands and assessing climate change related impacts. This research targets the Deer River watershed near Churchill, Manitoba, which represents a typical subarctic wetland system in the Hudson Bay Lowlands. An extensive field investigation was first conducted during the summer from 2006 to 2008 to facilitate in-depth understanding of the wetland hydrology. The results provided evidence to indicate a strong relationship between air temperature and evapotranspiration. Permafrost table, soil moisture and streamflow were monitored and analyzed to advance the acknowledgement of the climatic, geographical and hydrological characteristics of subarctic wetlands. To quantify the water cycle and further validate the findings from field investigation, a Canadian distributed hydrological model, WATFLOOD, was employed to simulate the hydrologic processes in the targeted watershed. The results demonstrated that snowmelt in the spring season (April-June) was the major source of water supplement of subarctic wetlands. Most light and moderate rainfall events in summer (July-September) generated relatively small amounts of runoff which can be related to canopy interception, depression storage, porous soil layers, impermeable permafrost and intensive evapotranspiration. A lag of 2-8 days between the peaks of rainfall and stream runoff was observed in both summer and fall. This study is expected to benefit wetland conservation and the assessment of climate change related impacts in the Canadian northern regions.
External Constraint and Shrinkage of Butt-welded Joints in the Erection of Assemblies on Building Way

As for the degree of external constraint of welded joints in ship construction, various discussions have long been made in connection with the problems of shrinkage and residual stress, but the magnitude of the constraint has been left unknown. On the degree of external constraint we adopted in this paper the following definition ; Degree of external constraint=Average value of transverse stress along weld line necessary to produce average dislocation of 1 mm along weld line, we obtained the magnitude quantitatively by applying two methods. The one is the method of measuring the change of root gap due to external load applied transversely to weld line before welding, and the other is the method of comparing average shrinkage along weld line due to welding with the shrinkage in free welded joint.The main results obtained in this paper are summarized as follows : (a) Degree of external constraint seems to be independent to thickness of plate and total weight of assembly. (b) Degree of external constraint is generally very small. About 60 per cent, of total butt joints measured showed the degree of external constraint less than lkg/sq. mm/mm, and none of them showed more than 10 kg/sq. mm/mm. (c) When the magnitude of degree of external constraint and welding conditions are definite, average locked-in stress increases a little with the increase of the thickness of plate.
Job Insecurity and Turnover Intentions among Banking Sector Employees: The Moderating Role of Organizational Support and Ethical Leadership

Purpose - Job insecurity exerts a significant impact on turnover intentions among employees. The association may be partly due to the influence of organizational support and the ethicality of leaders. However, there is a shortage of studies on the ameliorating role of organizational support and ethical leadership in the nexus between job insecurity and turnover intentions. Thus, the purpose of this study is to examine the nexus between job insecurity and turnover intentions among banking sector employees. The moderating role of organizational support and ethical leadership on the underlying relationship was assessed to achieve this. Design/methodology/approach – One hundred and sixty (160) banking sector employees were conveniently selected to participate in the study. The sample consisted of female (n = 92) and male (n = 68) employees, ranging from 23 to 49 years. Standardized measures were used in soliciting respondents' demographic characteristics, perceived job insecurity, ethical leadership, organizational support, and turnover intentions. Data were analyzed using regression analysis. Findings – Results revealed a significant positive correlation between perceived job insecurity and turnover intentions. Organizational support and ethical leadership also moderated the association between job insecurity and turnover intentions. The influence of job insecurity on turnover intentions minimizes when management provides the needed support and favorable climatic conditions. Originality/value – In general, the study highlights the importance of organizational support and ethical leadership in lessening the impact of job insecurity on turnover intentions.
Kluftmessungen im Gelände und ihre Bedeutung für die Bestimmung des tektonischen Spannungsfeldes in der Schweiz

Abstract. An intensive program of measurements of the orientation of joints in the field in Switzerland was undertaken in the Cantons of Graubunden, St. Gallen, Schwyz, Uri, Zurich, Zug, Aargau and Berne. For every «region», comprising 2–8 outcrops, the average orientation of the joint-parallelepiped was calculated by means of an electronic Computer based on a function-minimization program. If it is assumed that the steeply-dipping Joint surfaces have been produced by the present-day triaxial stress field according to the Mohr-Anderson theory of faulting, the orientation of the latter can be calculated. Thus, the net of present-day stress trajectories for Switzerland can be drawn. It turns out that the average orientation of the greatest compression in the region investigated is N 60°W. This agrees well with in-situ stress determinations by Gysel in the Sonnenbergtunnel near Lucerne (N 76.5°W) and by Greiner in southern Germany (N 28°–50°W). Converseiy, the hypothesis that most joints visible on fresh outcrops are due to the present-day tectonic Stresses and that the latter is homogeneous over extended areas, is thereby confirmed.
Molecular Docking and Quantum Chemical Computations of 4-Chloro-2-[(furan-2-ylmethyl)amino]-5-sulfamoylbenzoic Acid Based on Density Functional Theory

Abstract Quantum computational calculations of energies and geometries of 4-chloro-2-[(furan-2-ylmethyl)amino]-5-sulfamoylbenzoic acid have been performed by DFT level of theory using B3LYP/6-31G(d,p) basis set. The solid phase FT-Raman and FT-IR spectra of the Furosemide compound were recorded in the region 4000 cm−1 to 400 cm−1 and 4000 cm−1 to 400 cm−1 respectively. The molecular geometry, harmonic vibrational frequencies and bonding features of 4-chloro-2-[(furan-2-ylmethyl)amino]-5-sulfamoylbenzoic acid in the ground state have been calculated by using density functional theory (DFT) B3LYP method with standard 6–31 G(d,p) basis set. The scaled theoretical wavenumber showed very good agreement with the experimental values. The vibrational assignments were performed on the basis of the total energy distribution (TED) of the vibrational modes. Stability associated with molecule as a result of hyperconjugative interactions, charge delocalization has been analyzed utilizing Natural Bond Orbital (NBO) analysis through the use of B3LYP/6-31G(d,p) technique. The outcomes reveal that electron density (ED) within the σ* and π* orbitals which are antibonding second-order delocalization energies E (2) confirm the occurrence of intramolecular charge transfer (ICT) inside the molecule. Hirshfield surface analysis and Fukui functions calculation were also performed. From the calculations the first order hyperpolarisability was found to be 3.136 × 10−30esu. The molecule orbital contributions have been analyzed utilizing the total (TDOS), partial (PDOS), and overlap population (OPDOS) density of states. A molecular docking study has supported the anticonvulsant activity of the Furosemide molecule.
Neutral point clamped transformerless grid connected inverter having voltage buck–boost capability for solar photovoltaic systems

This study proposes a neutral point clamped grid-connected transformerless inverter for solar photovoltaic (PV) systems. This inverter has the capability to function in buck–boost mode. Thus the PV voltage level can be chosen to be of lesser value as compared to that of the existing buck type of inverters. This leads to increment in yield of power when PV modules are required to operate under mismatched conditions owing to possibility of more parallel connection of PV modules. Furthermore, buck–boost nature of the proposed inverter also facilitates operation under considerable variation in PV array voltage caused by wide changes in meteorological conditions. The other advantages of the inverter include: (a) elimination of concerns pertaining to the leakage current issues in transformerless grid-connected solar PV systems, (b) elimination of grid current sensor requirement, (c) elimination of shoot-through fault etc. The operating principle of the developed inverter supported by relevant analysis is presented. Control strategy devised for the inverter is provided. Results of detailed simulation studies carried out on MATLAB/Simulink platform are presented to ascertain viability of the proposed scheme. Exhaustive experimental validation has been carried out by utilizing a scaled down laboratory prototype of the proposed inverter.
Special issue introduction: what is the new state capitalism?

ABSTRACT This article introduces and lays the groundwork for this Contemporary Politics special issue on the ‘new’ state capitalism. We start by noting that the rubric state capitalism tends to elicit paradoxical responses, from uncritically embracing the term and overstretching its realms of application, to rejecting its validity altogether. We argue that the source of such ambivalence resides in issues of conceptual definition, which have led to a number of analytical impasses. We propose instead to construe state capitalism as a set of critical interrogations concerning the changing role of the state, thereby introducing a degree of plasticity in the use of the category. We call this the problématique of state capitalism. We subsequently identify three major themes that are explored in this dedicated issue, and that warrant further research in light of the COVID-19 pandemic, namely (1) its class underpinnings, (2) its global nature, and (3) its relational character.
FULL SCALE EXPERIMENTAL STUDY ON HIGH STRENGTH SLURRY WALL

This paper is written on the subjects of high-strengthing and thermal crack control of slurry wall. At first, this paper describes manufacturing and control method of high strength flowing concrete using low-heat-type cement, and then this paper investigates constructability of the concrete, degree of concrete segregation, compactability of concrete and characteristic of concrete strength which is placed into bore-filling slurry. As the result of mock-up test, authors obtained good quality concrete applying the method which authors propose for manufacturing and control of concrete. The concrete placed in the slurry showed desired results with high filling characteristics in spite of dense reinforcing bars.
Interactive Exhibitions : The Use of Interactivity in Educational Exhibitions

Tampereen ammattikorkeakoulu Tampere University of Applied Sciences Degree Programme in Media EEVA-KAISA AHLAMO Interactive Exhibitions The Use of Interactivity in Educational Exhibitions Bachelor's thesis 83 pages May 2013 The purpose of this thesis was to study the meaning and use of interactivity in educational exhibitions. The theory was explored first, clearing the idea of what interaction truly is and how it is used in museums and science centres. New ideas and suggestions from several different experts were also viewed and advantages and disadvantages of different interaction styles examined. The second part of the thesis was the research. The purpose of the research was to find out what level of knowledge people have about astronomy as well as how they tend to behave in interactive situations in a science centre. The data was collected partly in New Zealand, partly in Finland. The results followed the lines discovered in the theory part further enhancing its credibility. The third part consisted of creating concepts for an interactive astronomy exhibition. The concepts were supposed to be quite preliminary, but still give an idea about what type of concepts there could be in such an exhibition. During the process of making this thesis it soon became clear that this field is very complex and mixes several different areas from human intelligent to sociological behaviour and common sense. It does encourage the professionals to try different things, though, and its diversity gives motivation to the creative people. There was not enough room in this thesis to go very deep into some aspects. This is why there would still be material left for several other Bachelor’s theses in this area.
Modeling of Cell Deformation Under External Force Using Neural Network

Embryogenesis, regeneration and cell differentiation in microbiological entities are influenced by mechanical forces. Therefore, development of mechanical properties of these materials is important. Neural network technique is a useful method which can be used to obtain cell deformation by the means of force-geometric deformation data or vice versa. Prior to insertion in the needle injection process, deformation and geometry of cell under external point-load is a key element to understand the interaction between cell and needle. In this paper the goal is the prediction of cell membrane deformation under a certain force, and to visually estimate the force of indentation on the membrane from membrane geometries. The neural network input and output parameters are associated to a three dimensional model without the assumption of the adherent affects. The neural network is modeled by applying error back propagation algorithm. In order to validate the strength of the developed neural network model, the results are compared with the experimental data on mouse oocyte and mouse embryos that are captured from literature. The results of the modeling match nicely the experimental findings. © 2010 ASME
Analog Intelligent Wake-Up Systems for Wireless Sensor Networks

Analog Intelligent Wake-Up for Wireless Sensor Networks by Robert Joseph Fernandez Master of Science in Electrical Engineering West Virginia University David W. Graham, Ph.D., Chair The applications of Wireless Sensor Networks have grown exponentially over the last several years. These networks help to monitor environmental parameters such as temperature, humidity, pollution, motion, acoustics, and vibration in a variety of different ways. Each node (mote) in the network typically contains the following: a microprocessor, sensors, circuits that interface sensors with the mote, a radio transceiver, and a power source; typically a battery. These sensor networks typically work by having the mote’s Analog-to-Digital Converter (ADC) convert raw analog sensor data into digital, so processing can be done by the mote’s microprocessor. If an event of interest has occurred, the mote transmits relevant data using its radio. However, if the data being read by the sensors are not of interest, the power consumed by the processor and ADC is wasted. This valuable energy is being used because of the mote’s need to operate off of battery power. Presented in this work are several analog systems with the ability to use Analog Signal Processing (ASP) prior to sending an interrupt to a higher level system. The first system is modeled on work previously conducted by Brandon Rumberg, and is used as a spectral analysis wake-up system. This system is used to detect programmable frequency content. If the content matches a predetermined template, an interrupt is given and the mote is awakened from its sleep state. The second system discussed is a biologically inspired vision system. This system uses ASP to detect objects moving. If the object is moving in a programmable speed range, an interrupt is given and the mote will awaken from its sleep state. The third system is a redesigned version of the biologically inspired vision system. The new system detects motion similarly to the previous system, however it has the ability to detect object speed as well as direction. The ability to use ASP to pre-process the event before mote wake-up makes these two systems extremely important. By doing such, energy is saved and higher level processing is still possible once the information is converted into its digital form by the mote.
