Abstract The paper presents an efficient and simple fuzzy logic power system stabilizer (FLPSS) for damping electromechanical modes of oscillations and enhancing power system synchronous stability. The essential feature of the proposed controller is that the pole placement approach is used to assign the open-loop poles at certain specified locations at nominal operating point. Then the fuzzy logic controller is employed to excite the synchronous machine excitation system by an incremental signal for enhancing the power system stability over a wide range of operating condition and exciter gain. The input signals to the FLPSS is the speed deviation and speed deviation change. The simulation results using the proposed controller are carried out on an synchronous machine connected to infinite bus through transmission line.Moreover,a comparison between the conventional fixed-gain PI controller and the proposed FLPSS is presented. The results validate the effectiveness of the proposed FLPSS in terms of less ove...

Churg−Strauss syndrome is a rare diffuse vasculitis of which the ocular manifestations have been well documented. However, reports of conjunctival involvement in Churg−Strauss syndrome are scarce. Such a presentation is described in a man with Candida albicans infection as well as ankylosing spondylitis, and a possible aetiological linkage is established amongst all three.


The Dangin-Sangju Highway will contribute greatly to increasing trade between Korean companies in Chungcheong and North Gyeongsang and Chinese firms. Because the highway is expected to reduce secondary export expenses, which are Influenced by logistics costs and transportation time, it is also likely to enhance international competitiveness. The highway will also help to attract Chinese tourists traveling through Cheonju Airport, thereby contributing to the development of the tourist industry in areas along the highway. In addition, the close proximity of such ports as Pyeongtaek and Dangjin to those of Beijing, Qingdao and Shanghai, Wihai will greatly enhance international competition by reducing logistics costs.


current scenario, energy optimization for the electrical components used in the hand-held devices is a broad area of research. Energy principle for information technology contains its own specific energy behavior. The energy costs in server centre are now compatibility to the cost of hardware devices and other compare devices. In the processor device system, heat existing is a major cause of limiting changes in the performance evaluation. In laptop, scanners, computers, cell phones, printers, i-pods, and other digital devices, which are portable, reduced the power consumption converts into the battery long life manner. The energy consumption is now presenting challenges as a performance measure in computers, processing the task execution time. The energy is linked with the execution time capacity, where comparable patterns have been recognized by a combination of hardware devices, software devices, and algorithms. In this paper, the design of energy-efficient computer systems is proposed by the use of Bellman-ford algorithmic approach. A model is proposed for finding the performance of the system. Computed results are depicted in the form of tables and graphs.


The overall objective of this program was to develop regenerable sorbents for use in the temperature range of 343 to 538 C (650 to 1000 F) to remove hydrogen sulfide (H{sub 2}S) from coal-derived fuel gases in a fluidized-bed reactor. The goal was to develop sorbents that are capable of reducing the H{sub 2}S level in the fuel gas to less than 20 ppmv in the specified temperature range and pressures in the range of 1 to 20 atmospheres, with chemical characteristics that permit cyclic regeneration over many cycles without a drastic loss of activity, as well as physical, characteristics that are compatible with the fluidized bed application. This topical report focuses on the investigation directed toward preparation of zinc-based sorbents using the sol-gel approach that has been shown to require only a moderate temperature for calcination, while resulting in significantly more attrition-resistant sorbents. The sorbents prepared in this part of the investigation and the results from their evaluation in packed-bed and fluidized-bed reactors are described in this report.


Degenerate four-wave mixing (DFWM) for co-propagating femtosecond laser pulses is considered in the axial-symmetric case for bulk medium with cubic nonlinear response, if pump-wave amplitudes are being equal. Computer simulation is based on the set of nonlinear Schrödinger equations describing this process. For the analytical consideration we use the frame-work of both plane wave approximation and long pulse duration approximation taking into account the phase matching. In opposite to widely used approach, based on the pump-waves non-depletion, the problem invariants are used for analytical solution developing. The solution demonstrates various DFWM modes existence and allows us to provide full analysis of the problem in dependence of its parameters. Analytical solution and derived pulse interaction modes can explain complicated regime of DFWM, which may appear at different intensities of interacting waves.

Morphological and stevioside parameters in three diverse genotypes (GVS-6, HPSR and MPSR) of Stevia rebaudiana were studied under hot and semi- humid climatic conditions of Nagpur, for three years (2008–2010). The cultivar GVS-6 was identified as most promising for high stevioside content and biomass yield. The variations in morphological parameters of stevia cultivars were significant. Pooled results revealed that cultivar GVS-6 has optimum plant height (36.4 cm) with highest branches (14 number) and leaves (199.9 number), higher total dry biomass yield per plant (126.0 g) and stevioside (49.8%). High biomass production and stevioside content in a variety of stevia is very important for economic valuation in agriculture and medicinal aspects.


The risk of fire in hospital had the highest rating compared to another places, because in every single task was done by using electrical energy as a primary energy source. The existence of a fire management system in hospital was not enough to overcame the fire without knowledge and the ability of fire emergency response that might be possessed of all workers. The general purpose of this research to analyzed the correlation between knowledge and application of fire emergency response on nurses in patient care installation of general hospital of Pasar Rebo, East Jakarta. The specific purpose of this research to analyzed the correlation between the characteristics of participant and application of fire emergency response. The characteristics of participant included fire safety education, fire safety training, fire experience, age, and working experience. This research was an analytic quantitative research by cross sectional approach. The participants of this research were 65 nurses. By using the correlation test, the results showed that there was not a significant correlation between participant's characteristics (fire safety education, fire safety training, fire experience, age, and working experience) and application of fire emergency response (p >0,05). And also there was not a significant correlation between knowledge and application of fire emergency response (p >0,05). The general hospital of Pasar Rebo was expected to held the fire safety education and fire safety training regularly, at least once a year.


Gas-particle heat transfer rates are investigated using particle-resolved direct numerical simulation (PR-DNS). We utilize a discrete element method (DEM) approach to first obtain a realistic packing of the particles, and then build a computational mesh based on these particle positions for running PR-DNS. A common challenge in such investigations is the overlap between particles, which can result in highly skewed cells. In this work, this problem is dealt with by shrinking the particles. Simulation results showed that changing the packing porosity by shrinking the particles by different amounts does not match recently proposed correlations. Particle arrangements produced in this way will over predict the heat transfer rate. When a random particle arrangement was simulated, however, results matched well with correlations. In addition, we find that DNS results using the commercial CFD code ANSYS FLUENT and the open-source code OpenFOAM® return very similar results. The computational performance was similar, with (i) OpenFOAM being faster for a fixed number of iterations, and (ii) ANSYS FLUENT requiring a smaller number of iterations to find convergence.

Introduction: The treatment of complicated parapneumonic effusion (PPE) and thoracic empyema (TE) is controversial; and the choice of treatment after confirming the failure of simple drainage remains unclear. The purpose of this study was to compare the outcomes of intrapleural urokinase (UK) administration and video-assisted thoracoscopic surgery (VATS) as initial treatment options for PPE and TE. Materials and Methods: We retrospectively reviewed and compared the data of 20 patients with PPE and TE diagnosed between January 2010 and December 2012 at our hospital, dividing them on the basis of the initial treatment into a video-assisted thoracoscopic surgery (VATS) group (n=9) and UK group (n=11). Results: Age was the only statistically different parameter between both groups (P=0.025); with the mean age of the VATS and UK groups being 64 and 76 years, respectively. There was no significant difference in the duration of drainage or success rate between the UK or VATS groups. Although no statistically significant differences (P=0.20) were observed, duration of hospital stay was longer in the UK group (21 and 28 day for VATS and UK, respectively). Conclusion: VATS for PPE and TE may shorten the duration of hospital stay.However, UK administration may be used for selective patients because it is considered to yield outcomes similar to VATS.

Objective To systematically review therapy-related complications incidences of warfarin with dif erent anticoagulation intensity in Chinese at er mechanical heart valve replacement, and to explore the suitable anticoagulation intensity of warfarin. Methods We electronically searched The Cochrane Library(Issue 2, 2013), EMbase, Pub Med, CNKI, CBM, Wan Fang Data and VIP for studies about therapy-related complications rates of warfarin with dif erent anticoagulation intensity in Chinese at er mechanical heart valve replacement from inception to March 2013. Two reviewers independently screened literature according to inclusion and exclusion criteria, extracted data, and assessed methodological quality of included studies. Then meta-analysis was performed using Rev Man 5.2. Results A total of 7 studies involving 3 787 cases were i nally included, 2 985 cases in Group A(targeted INR ≤ 2.3) and 802 cases in Group B(targeted INR 2.3). The results of meta-analysis showed that, compared with Group B, the total therapy-related complications incidence of warfarin with dif erent anticoagulation intensity significantly decreased in Group A(OR=0.35, 95%CI 0.28 to 0.44, P0.000 01). The incidence of hemorrhage in Group A(OR=0.15, 95%CI 0.08 to 0.27, P0.000 01) was lower than that in Group B. However, the incidence of embolism in Group A was higher than that in Group B(OR=2.77, 95%CI 1.54 to 4.98, P=0.000 7). Conclusion Applying low-intensity anticoagulation for Chinese patients at er mechanical heart valve replacement could reduce the overall incidences of anticoagulation-related complications and hemorrhage, but it could also significantly increase the incidence of thrombosis.


Abstract : This work describes the development of a four-pin probe and associated electronic instrumentation for making time and space resolved measurements of electrical conductivity in MHD plasma flows. Measurements were made in 2000 K atmospheric-pressure potassium-seeded (0.1% by weight) argon flowing at velocities between 10 and 100 meters/sec. The results show a dependence of indicated conductivity on flow speed and probe orientation, so that calibration is necessary for high accuracy absolute conductivity determinations. The probe is well suited for time and space resolved relative conductivity fluctuation measurements, and for continuous display of time-averaged indicated conductivity. (Author)


In this paper, a new adaptive time-stepping procedure for dynamic limit analysis is suggested to calculate the optimal time step size. Three posteriori error estimators are used for control of time step size. The local velocity error estimator proposed by Zeng, Wiberg and Xie is applied for the assessment of the error by discretization of time domain. In dynamic limit analysis, it is assumed that the material is perfectly plastic in time interval. Due to this assumption, two types of error estimator are newly proposed for evaluation of the error of strain energy increment. Numerical simulation has been carried out in order to verification of proposed adaptive time-stepping procedure. The result with relatively small and fixed size of time step is assumed to be exact. The result from adaptive time stepping is compared with the result using same number of time step. The analysis result demonstrates the efficiency of the adaptive time-stepping procedure suggested in this paper.

Mobile communication services raise user privacy concerns in sharing the traveling trajectories while facilitating people's daily lives. According to these shared trajectories, adversaries can dig users' multi-modal behavioral semantics by combining with extensive open-source web information. These behavioral semantics have differentiated privacy sensitivity, raising different levels of privacy concerns. It makes users have personalized requirements for protecting their travelings. Resulting in the inevitable evolutionary trend from location privacy protection to differentiated location privacy protection (DLPP). DLPP digs into mobile semantics and characterizes the differentiated location sensitivity by simulating the potential attacks. It provides the privacy protection with differentiated strength to each location. Differentiated and appropriate strength well balances the tradeoff between privacy protection and data availability for the quality of application service. We are motivated to conduct a comprehensive survey on DLPP from the semantic perception perspective. It forms a complete overview of the mobile semantics-aware differentiation in location privacy protection. Specifically, we first review the research works on multi-modal mobile semantic representation. Then, taking the dug semantics as a clue, we summarize the basic principles of DLPP research systematically. To complete the overview, we also summarize their design modes and discuss the open opportunities and challenges for future works.


In the current industry 4.0 scenario, good quality cutting tools result in a good surface finish, minimum vibrations, low power consumption, and reduction of machining time. Monitoring tool wear plays a crucial role in manufacturing quality components. In addition to tool monitoring, wear prediction assists the manufacturing systems in making tool-changing decisions. This paper introduces an industrial use case supervised machine learning model to predict the turning tool wear. Cutting forces, the surface roughness of a specimen, and flank wear of tool insert are measured for corresponding spindle speed, feed rate, and depth of cut. Those turning test datasets are applied in machine learning for tool wear predictions. The test was conducted using SNMG TiN Coated Silicon Carbide tool insert in turning of EN8 steel specimen. The dataset of cutting forces, surface finish, and flank wear is extracted from 200 turning tests with varied spindle speed, feed rate, and depth of cut. Random forest regression, Support vector regression, K Nearest Neighbour regression machine learning algorithms are used to predict the tool wear. R squared, the technique shows the random forest machine learning model predicts the tool wear of 91.82% of accuracy validated with the experimental trials. The experimental results exhibit flank wear is mainly influenced by the feed rate followed by the spindle speed and depth of cut. The reduction of flank wear with a lower feed rate can be achieved with a good surface finish of the workpiece. The proposed model may be helpful in tool wear prediction and making tool-changing decisions, which leads to achieving good quality machined components. Moreover, the machine learning model is adaptable for industry 4.0 and cloud environments for intelligent manufacturing systems.

ABSTRACT IT HAS been reported by Atwood and Weakley (1924) as well as by Smith (1931) that infertile chicken eggs lose CO2 during storage. According to Smith (1931) the CO2 loss of individual eggs may begin at a rate of 9.0 mg. per day and gradually drop to 0.1–0.2 mg. per day, at which level it may continue for 100 days or more. Smith (1931) also found that the rate of CO2 loss depends on temperature. The CO2 content of fresh eggs has been determined by Mathieu and Urbain (1908) and Straub and Donck (1934). These investigators found that the albumen of fresh eggs contains approximately 55 mg. CO2 and that there is no CO2 in the yolk. Numerous experiments on storage of eggs at high CO2 concentrations as well as experiments on different methods of shell sealing have demonstrated the importance of CO2 with regard to maintenance of interior . . .


An understudied example of an early modern suburb, Roland Park, Baltimore (constructed 18911915) bridges the gap between the streetcar suburbs of the late nineteenth century and the tract suburbs of the mid-twentieth century. As an early modern suburb, the development of the Roland Park led to the formalization and creation of many of the social and cultural norms in addition to the landscape elements of today's modern suburbs. This thesis examines these elements, by-products of the formation of an elite community, focusing on the regulation of Roland Park's space in protecting it from the real and perceived negative influences of the outside world. Moreover, the thesis explores in depth the peopling of Roland Park's built environment, a topic of great importance to the success of the community. Finally, the research places Roland Park in the larger spatial and temporal contexts of the development of other Baltimore communities, of other elite suburban developments within the United States, and the broader, global history of suburbs.


The final lesson in this cycle of studies on "Discipleship" prompts the question, What will it "cost" Laodicea to be in partnership with Christ our High Priest in His mission to the world? There is a difference between fulfilling the great commission,—"Go ye ... and teach [disciple] all nations,"—before 1844 and being co-laborers with the Harvester during the cleansing of the sanctuary. It will cost Laodicea everything she thinks she knows about righteousness by faith in exchange for an appreciation of what it cost the Son of God to obtain justification by faith which is parallel to and consistent with the at-one-ment with God. This is the "offense" of the 1888 message. Why is Laodicea's discipleship and devotion to Jesus lukewarm and lackluster? The True Witness diagnoses her disease which is causing Him acute nausea,—"I am about to spue thee out of my mouth" (Rev. 3:16).

A cross-sectional analysis was performed to determine risk factors associated with hypertension in 1,238 chronic hemodialysis patients upon enrollment into the HEMO Study. The mean pre- and post-dialysis systolic blood pressure were 152.4 ± 25.0 (mean ± SD) and 137.8 ± 24.6 mm Hg, respectively. The mean pre- and post-dialysis diastolic blood pressures were 82.1 ± 14.8 and 74.7 ± 13.8 mm Hg, respectively. Less than 30% of the study cohort had blood pressures that were normotensive by JNC VI guidelines. Risk factors associated with higher pre- and post-dialysis systolic blood pressures included the presence of diabetes mellitus, older age, increased number of prescribed antihypertensive medications, lower hematrocrit, and absence of arrhythmias. Variables associated with higher pre- and post-dialysis diastolic blood pressures included younger age, increased number of prescribed anti-hypertensive medications and absence of arrhythmias. There was also a nonlinear relationship between blood pressure and prescribed total ultrafiltration volume. A total ultrafiltration volume of >2.5 kg was associated with an elevation in pre-dialysis systolic and diastolic blood pressures. A total ultrafiltration volume of ≤2.5 kg was associated with an elevation in post-dialysis systolic and diastolic blood pressures. These data on ultrafiltration volume suggest that higher pre-dialysis blood pressures may be associated with excessive interdialytic weight gains due to patient noncompliance with fluid restriction and that higher post-dialysis blood pressures may be associated with a prescribed dry weight that is higher than the patient's true dry weight. Better management of these parameters may improve the prevalence and severity of hypertension in this population.


In this work, a simple catalyst-free vapour-solid deposition method is applied for controlled obtaining of two types (planar and disordered) continuous Bi<inf>2</inf>Se<inf>3</inf> nanostructured thin films on different (fused quartz/glass, mica, graphene) substrates. Performed for the deposited thin films transport and thermoelectric characterization (type, concentration and mobility of the main charge carriers, Seebeck coefficient and power factor) showed that proposed deposition method allows to fabricate "low-doped" Bi<inf>2</inf>Se<inf>3</inf> thin films with power factor comparable and even higher than reported for the Bi<inf>2</inf>Se<inf>3</inf> thin films fabricated by molecular beam epitaxy technique.


As a streamer discharge develops in the water, it releases spherical shockwaves from the head of a streamer filament, leaving a chain of discrete shockwaves around the filament. The position of the center of each shock wave is a good indicator of the position of the filament head at a certain moment. The velocity of shockwaves released from the filament head decays to the acoustic velocity (1450 m/s) in water after spreading for ~0.5 mm. Based on these characteristics of shockwaves, we developed a method for measuring the propagation speed of a streamer discharges in water, enabling to investigate the difference in propagation behavior of many filaments generated in a single discharge pulse. Based on this method, we investigated the difference in propagation behavior of many filaments generated in a single discharge pulse at water conductivity of $20~\mu \text{S}$ /cm and 26 kV. We found that the filaments generated in the same discharge pulse have significantly different propagation speeds, and confirmed that the propagation speed of a filament will significantly slow down after a longtime pause.

In the US people with intellectual and developmental disabilities (I/DD) comprise one of the most likely groups to experience traumatic life events. These experiences often produce negative effects (e.g., stress, anxiety, grief, numbing, etc.) that need to be managed. Methods such as emotional self-regulation are often used to help people cope when these effects present themselves post-trauma. In recent years mobile-computing-devices-based apps have been increasingly used to help the general population with autonomous self-regulation. However, none of these is designed for people with I/DD or is cognizant of the trauma they experience in their lives. We interviewed eight (8) practitioners at a trauma services organization that, among other things, helps people with I/DD learn and practice post-trauma self-regulation. The goal of the interviews is to understand what it would take to build post-trauma self-regulation apps for people with I/DD. Based on the interview responses we argue for a set of guidelines, based on the social work practice of trauma-informed care, to design post-trauma self-regulation apps for people with I/DD.


OBJECTIVES
To investigate the effect of 5% lidocaine patches on postoperative analgesia in dogs undergoing hemilaminectomy.

MATERIALS AND METHODS
Client-owned dogs undergoing hemilaminectomy for a single acute intervertebral thoracolumbar disc extrusion were enrolled in this prospective, randomised, blinded clinical trial. Following methadone administration, anaesthesia was induced with propofol, and maintained with isoflurane in oxygen and fentanyl infusion, in both groups. After skin closure, two 1∙5 cm wide 5% lidocaine patch strips were attached along both sides of the wound in dogs allocated to Group L. In Group C, the two lidocaine patch strips were applied but the transparent isolating liner was not removed. Postoperatively, all dogs received a non-steroidal anti-inflammatory drug, gabapentin and diazepam. Methadone was administered according to the short form of Glasgow Composite Pain Scale with pain assessed every 2 hours for 48 hours by observers unaware of the treatment.

RESULTS
Thirty-nine dogs completed the study. Demographic data, end-expiratory fraction of isoflurane, fentanyl consumption, anaesthesia and surgical times were similar between groups. The number of dogs requiring postoperative methadone and the number of doses of methadone administered were not different between groups. No macroscopic skin reaction was noticed once the patches were removed.

CLINICAL SIGNIFICANCE
In this setting, 5% lidocaine patches did not provide additional postoperative analgesia in dogs undergoing hemilaminectomy.


The volatile composition of the Verde di Macerata cauliflower after blanching up to 3 min and frozen at -20°C for 12 months are monitored. The fresh and stored cauliflowers were homogenised in a hammer mill and then liquefied with maceraticand pectinolytic enzymes. The aroma compounds were extracted from the juice by evaporation and then adsorbed on the resin. The volatile extracts were analyzed by GC/MS-SIM. The results obtained showed that the blanching caused a decrease of sulphurs, an increase of thionitriles, a release of isothiocyanates and nitriles. The frozen storage determined an ulterior decrease or disappearance of isothiocyanates, sulphurs and a considerable increase of thionitriles, in particular in the first 6 months.


The main goal of the present study is to identify the prevailing atmospheric circulation patterns (circulation types) that are associated with the occurrence of precipitation (both mean and extreme) over southern Romania. A daily circulation type calendar derived from an automatic and objective classification scheme is used in synergy with the daily precipitation time series from five weather stations in the study area for a sixty-year period (1961–2020). Both mean and extreme precipitation do not show statistically significant trends, except for the annual precipitation at Constanța, for the value with daily precipitation totals greater than the 95th percentile at Craiova and the number of days exceeding the 99th percentile at Buzău and Râmnicu -Vâlcea, where significant negative trends were noticed. Moreover, the precipitation trends were analyzed in relation to the atmospheric circulation types. Non-significant positive trends were observed for the precipitation amounts (annually, winter, spring, and autumn) corresponding to very rainy circulation types (C, Cwsw), while for summer, the equivalent trends were negative. Moreover, it became evident that during extreme precipitation events, the predominant circulation types (C, Cwsw) are associated with western or almost western atmospheric circulation and Mediterranean- or Atlantic-originated depressions.


In the randomized PROVE IT–TIMI 22 trial, sponsored by the maker of pravastatin, acute coronary syndrome (ACS) patients with total-cholesterol levels ≤240 mg/dL had significantly better clinical outcomes at 2 years with an aggressive LDL-lowering strategy (a 70-mg/dL target using 80 mg/day of atorvastatin) than with a standard strategy (a 100-mg/dL target using 40 mg/day of pravastatin); see Journal Watch Cardiology Apr 16 2004. In two new substudies, researchers investigated important aspects of the aggressive …


We will be looking at fields K of characteristic 0. More precisely, think Q for the first part, and C(t) for the final part. Recall that an element α which is algebraic over K has associated to it a Galois group G(K(α)gal/K) as a subgroup of some symmetric group Sn. Writing GK = Gal(K/K), we have the Grothendieck-Galois correspondence (an equivalence of categories between finite GK-sets and finite varieties over K) GK–FinSets ↔ FinVar/K X(K) ↔ X = Spec ∏


Background: Symbolic play test (SPT) is a simple test for screening preverbal language in children. This test had been validated in English‐speaking children. However, the toys may not be useful for other cultures such as Orientals like Chinese, Japanese, Koreans or Thais as they use chopsticks and bowls as eating utensils rather than spoon, fork or knife. The aim of this study was to find a set of miniature toys suitable for children of Oriental ethnic origin in order to get a reliable language test.


Granovetter who is an American sociologist and other sociological scholars have thought the relation among people could be divided into strong connections and weak connections. Strong connections are often the links of the same groups, and weak connections are often the links of the different groups. According to the spread of information, strong ties are weak, but weak ties are strong. In the light of the trust of society, the clan trusts exit in strong connections, and the foundation of weak connection is impersonal trust of society. All these perspectives can be applied to explain well the building and development of the clan business. It should make use of strong connections at the time of its building, but it must hold tight weak connections fully on stage of its development.

The Volume 1 report for this study proposes an integrated design approach for coal-fired power plant environmental controls. Two characteristics distinguish the integrated environmental control (IEC) approach as defined in this study from historical design approaches. First, all major environmental control subsystems are considered to equally influence costs and overall plant performance until preliminary analysis indicates otherwise. This assures benefits derived for one subsystem (e.g., solid waste disposal) do not increase complexity for other subsystems (e.g., water management) to the level where total plant costs are higher. Second, the IEC approach maximizes compatibility between equipment, fuel properties, and site characteristics. This allows the least complex environmental control system (ECS), lowering cost and minimizing potential operating problems. The IEC design strategy, described in detail in Section 2 and Appendices A-D, can reduce ECS costs in two ways. First, the IEC approach helps insure cost savings derived for one subsystem are not offset by other increases, raising total ECS costs. Second, reliability can be increased and potential operating problems reduced if equipment and control strategies selected are most compatible with the site and fuel characteristics, and thus most simple. Selection of the best control strategy for given site and fuel characteristics ismore » aided by a technical/economic analysis, described in Section 3, that allows ECS costs and technical features to be analyzed. 17 figs., 14 tabs.« less

Conversations with and among students in their residential environment illuminate the role of peer subcultures in shaping what students learn and how they define learning. An excerpt from a year-long ethnographic case study examines the ways in which residents of an undergraduate women's residential unit at a state comprehensive university talk about academic activity. It illustrates how female students talk about learning and speculates about the interaction between that talk and their curricular experiences. Two themes which emerged from the data are highlighted: (1) a shared sense of personal cost-benefit analysis by which women residents set limits on the expenditure of time and energy for academic pursuits; and (2) taboos which constrain conversations with co-residents about intellectual topics or curricular content.

PracticeRat® (Sharpoint, Reading PA) is a system containing a simulation vein, artery and nerve, designed as an alternative to live animal use in microsurgical training. We find PracticeRat® to be more expensive than living models. However, it does decrease animal usage and provides a very convenient opportunity to practice microsurgical techniques and procedures in a fairly realistic manner. Trainees can practice anytime, for any length of time, wherever microscopes are available. In this regard we find PracticeRat® to be a useful addition to microsurgical training programs and an excellent tool for skills maintenance. © 1995 Wiley‐Liss, Inc.

Explora Biolabs (Explora), a San Diego-based contract research organization (CRO), was founded in 2004 with a goal to satisfy the in vivo research needs of drug discovery researchers. We have used disposable caging from its inception in 2005, attracted by the simplicity of a disposable cage operation, the low capital investment required, the increased consistency and sterility it offered to our processes, and, of course, by the ease of its deployment.


In this work, the advanced treatment of the biologically treated wastewater of a textile plant using combination of ozonation and two-stage biological aerated filter (BAF) was studied. Comparing different ozone dosing methods, it was found that the integrated device including ozonation and BAF, allowed a higher COD (chemical oxygen demand) and color reduction. Comparing different treatment processes, it was found the combination of the integrated device and up-flow biological aerated filter allowed a higher pollutant reduction. After the ozonation and two-stage biological treatment, an effluent was obtained with the average COD of 26.7 mg/L, turbidity of 4.2 NTU, SS(suspended solid) of 2.0 mg/L, ammonia nitrogen of 0.6 mg/L and color of 2 degree.


Introduction: Duik's theory deals with subjective beliefs that people have about their own intelligence. Subjective beliefs that intelligent students have about their own intelligence could be effective on creative, analytical, practical intelligence as well as their goal orientation.

Conclusion: According to the findings it is recommend that for increasing the level of merit motivation of intelligent students, additive intelligence education based on Duik's theory should be used.


The use of thin-bonded concrete overlay (TBCO) pavements is rapidly emerging as a viable means of rehabilitating concrete pavements. In recent years, several projects have been constructed, and valuable information has been gathered with the Iowa Department of Transportation leading the way. A survey of the available literature, however, reveals that the information is scattered and, in most cases, it is difficult to make statistical inferences because either the information was not collected for any particular purpose (i.e., not task-oriented) or there is no prior well-defined experiment design. During the summer of 1983, an experimental 1,000 ft of thin-bonded concrete overlay pavement was placed on Interstate 610 (Loop 610), a 4-lane divided freeway in Houston, Texas. The original pavement structure is a continuously reinforced concrete pavement. Five design sections were constructed. Concrete reinforcement and overlay thickness were used at three and two levels, respectively. Presented in this paper are several aspects of the experimental project. First, the experiment design is discussed, along with project specifications, and a measurement program. Second, actual construction is presented, and salient features outlined. Third, initial results (including field and laboratory tests, Dynaflect deflections, and road profile data) are analyzed. Fourth, a 6-month performance report is made. In closing, conclusions and recommendations derived from the study are presented for those individuals and agencies contemplating the use of TBCOs for the rehabilitation of portland cement concrete pavements.


We define the functionality of systems in a geographic domain and use this definition to formulate a new quantitative indicator of sustainability, the Index of Sustainable Functionality (ISF). The ISF is a measure of the functionality of the processes underlying a particular standing stock and so provides a simple and objective assessment of the ability of a system to absorb an external or internal perturbation without losing the ability to recover. The ISF, for a geographic domain, is the sum of the values of quantitative indicators of the functionality of the underlying processes weighted by the stakeholders' priorities. To illustrate the methodology, we derive the ISF for the State of Western Australia and showed that, for Western Australia, economic measures of progress such as the Gross State Product used by the Government to guide the policies of the state, do not adequately reflect changes in our quality of life or the health of the ecosystem.


Recently, the C—H functionalization strategy for the construction of heterocycles has received substantial attention because of its economic, sustainable and environmentally benign features. Many kinds of heterocycles have been synthesized via transition metal-catalyzed sp 2 C-H functionalization. The new strategy for the construction of heterocycle scaffolds includes intramolecular cyclizations and intermolecular cyclizations, namely multicomponent reactions (MCRs) that achieve the formation of multiple bonds in one operation. This review introduces the synthesis of carbazoles, benzoxazoles, benzimidazoles, 2-substituted benzothiazoles, 3-aryl/alkylind-azoles, indoles, oxindoles, indolines, benzolactams, phthalimides, dibenzofurans and bridgehead unsaturated bicyclic enamines by the new strategy. The orientation of the cyclizations depends mainly on steric factors in cases where two regioisomers can be obtained. The regioselectivity of cyclizations is high in most cases, the cyclizations are even exclusive to give one sole product without the regioisomer in some cases. The functional group tolerance is good in most cases, halogen atoms and even iodine atoms are tolerated by the new strategy in some cases, providing a handle for further functionalization. The described strategy is being rapidly developed. Versatile features of the strategy have emerged, this review tries to classify the reported methods and inspire further investigations.


The multiplication-induced breakdown (MIB) in buried-channel (BC) P-MOSFETs is studied by means of numerical simulation, thus leading to a better comprehension of its physical mechanism. On this basis an analytical model is derived and verified according to measured breakdown characteristics. The very good accuracy of the model (error of the order of 5%) is demonstrated.


ICAtect is a knowledge based system that provides an interface between expert systems, simulation packages and CAD systems used for preliminary architectural design. This thesis describes its structure and development.The principal work discussed in this thesis involves the formulation of a method for representing a building. This is developed through an examination of a number of design tools used in architectural design, and the ways in which each of these describe a building.Methods of enabling data to be transferred between design tools are explored. A Common Building Model (CBM), forming the core of the ICAtect system, is developed to represent the design tools knowledge of a building. This model covers the range of knowledge required by a large set of disparate design tools used by architects at the initial design stage.Standard methods of integrating information from the tools were examined, but required augmentation to encompass the unusual constraints found in some of the design tools. The integration of the design tools and the CBM is discussed in detail, with example methods developed for each type of design tool. These example methods provide a successful way of moving information between the different representations. Some problems with mapping data between very different representations were encountered in this process, and the solutions or ideas for remedies are detailed. A model for control and use of ICAtect is developed in the thesis, and the extensions to enable a graphical user interface are discussed.The methods developed in this thesis demonstrate the feasibility of an integrated system of this nature, while the discussion of future work indicates the scope and potential power of ICAtect.


The British Terrorism Act 2006 introduces two new offences prohibiting direct and indirect encouragement of terrorism. The offences purport to extend the traditional approach adopted in British law to the offence of incitement for the purposes of encouragement of terrorism, and have been criticised for being both unacceptably vague and a disproportionate interference with the right to freedom of expression. This article examines the key elements of the actus reus of these new offences with a view accurately to delineating their scope and extent, and analyses the offences against the requirements of Art. 10 of the European Convention on Human Human Rights.


This article develops an intelligent underfrequency security control mechanism for offshore island power systems, for which frequency stability is a major concern. The security control mechanism is divided into two main categories: preventive control and corrective control. The developed preventive?corrective control system involves modules for forecasting the frequency nadir, the rate of change of frequency, intelligent load shedding, and protection strategies. The forecasts assist in the rescheduling of diesel generators, wind power curtailment, or intelligent underfrequency load shedding (UFLS). An actual island power system is considered to elucidate the feasibility of the proposed control system. The results of this study provide system operators with a valuable reference for preventive dispatch and the planning of load shedding.


Global supply chains are prone to market failures more than any other mode of organizing value-creation activities. Their characteristics challenge traditional means for correcting for market failures. Focusing on the failure of markets to distribute value among participants in labor-intensive global supply chains, I develop theoretical rationale for a new approach to address this failure. Building on interdependence theory, I suggest that inherent interdependencies among participants give them the power to change incentives and create markets for social justice. I identify the cultural, institutional, and political conditions that determine the effectiveness of the interdependence logic as a force for change. The theory extends the range of agents of change beyond those possessing direct regulatory power to include multiple governments, international organizations, NGOs, and firms. It broadens the mechanisms to address market failures and incorporates 'private regulation', legitimation processes and soft law as means for directing outcomes towards socially-desired value distribution.

We report the energy scaling of mode-locked fiber lasers using a large-mode area chirally-coupled core fiber. This is a demonstration of the scaling of ultrafast fiber oscillators to large cores in an all-solid glass package that holds the lowest order fiber mode while maintaining compatibility with fiber fusion technology. An all-normal dispersion cavity design yields pulse energies above 40 nJ that dechirp to durations below 200 fs. Using lower net dispersion, pulses dechirping close to 100 fs are obtained with pump limited energies. Effectively single-mode operation is confirmed by beam quality as well as spectral interference measurements.


Investigations were carried out to evaluate lipid class and fatty acid composition of Chlorella vulgaris in relation to several combinations of cadmium (2 × 10−8; 10−7 M Cd) and nitrogen (2.9 × 10−6 to 1.1 × 10−3 M N) concentrations. Triacylglycerols (TAG), acetone mobile polar lipids (AMPL) and phospholipids (PL) were the major lipid classes of C. vulgaris under all the tested conditions. TAG was the lipid class accumulated in the highest amount in N-limited C. vulgaris. The AMPL lipid class was lowest at the lowest N and highest Cd treatment. High proportions of saturated fatty acids (SAFA) and monounsaturated fatty acids (MUFA) in the total lipid extracts were recorded under N limitation in the presence of Cd. 16:1(n-11) was an exception among the MUFA as its levels decreased at low N. Total polyunsaturated FA (PUFA), ω3 PUFA levels, and PUFA:SAFA ratios increased with increasing N concentrations, but when exposed to Cd, their levels were significantly reduced. Unlike the other PUFA, 18:2(n-6) increased with increasing N limitation. Significant negative relationships between TAG, MUFA and SAFA with N were recorded. Cd had a positive correlation with TAG, while N was with AMPL, PL and PUFA. In conclusion, a combination of N limitation and Cd stress significantly altered the lipid composition of C. vulgaris, and N limitation had the most significant overall effect on lipid class and fatty acid composition of the microalga.


The general aim of the project was to explore causes and consequences of an apparently increasing movement of lower income households to relatively inconvenient residential locations in Melbourne and corresponding movement of more affluent households to more convenient locations. Consequences were expected to include increased dependence by lower income households on car use, increasing petrol related travel costs relative to incomes, and other social equity effects. There were four objectives: (I) to understand the processes underlying households' location decisions in Melbourne and thereby accounting for the social distribution of convenience to public transport, education, employment and other services; more specifically, to understand the role of (changing) constraints in those processes; (II) to understand the consequent (changing) social distribution of car dependence; (III) to develop guidelines for urban policy to enable less constrained residential location decisions (and to raise the question of whether such decisions would lead to reduced car dependence and lower travel costs relative to incomes); and (IV) to develop guidelines for policies to ameliorate the social effects of transport price rises on lower income households. At a general level, the study has demonstrated the need to see changing transport use--including changes in modes of travel for the journey to work--in the context of changing processes of intra urban migration. It has also demonstrated that travel decisions and intra urban migration must in turn be understood as part of an interrelated set of choices (albeit constrained) to do with workforce participation, workplace location and housing.

ABSTRACT
 As a refugee from Nazi Germany, the renowned weaver and textile artist Anni Albers was well-acquainted with the stresses of a nomadic life. So was Marguerite Wildenhain, the Bauhaus-trained potter who fled Europe to help found Pond Farm, a new artist collective in northern California. In this essay, I consider how both artists reflect in their writings on the relation between their respective craft practices, the mobility of modern societies, and their experiences of exile in the post-war United States.


In this paper, the design of PR regulator which is applied on the grid-connected inverter with LCL-filter, is analyzed in details. By modeling the system under stationary frame, the open and close-loop transfer function is given, which is used in analyzing the impact of each parameter on root locus. Using the root locus theory, the proper parameters are selected so that the resonance of LCL-filter is attenuated, the current ripple is suppressed and the sinusoidal input is well tracked, which means the output grid current is of high quality. A 10kW prototype is built and the result of the experiments verified the effectiveness of the proposed PR regulator design.


MAGIC is presently the imaging atmospheric Cherenkov telescope with the largest reflecting surface and the lowest energy threshold. MAGIC concluded its first year of regular observation in April 2006. During this period and the preceding commissioning phase, 25 Active Galactic Nuclei have been observed and VHE gamma-ray emission has been confirmed by 4 of them. Two more AGNs have been detected as gamma-ray sources with high statistical significance for the first time. We report in this paper the results obtained analyzing data of the detected sources. Temporal and spectral properties of detected signals are shown and discussed.

In this study, nanoscale zero‐valent iron (NZVI) particles were synthesized and utilized to integrate with surfactant and electrokinetics for the remediation of perchloroethylene (PCE). The average particle diameter and specific surface area of the lab‐synthesized iron particles were 109.3 nm and 129.7 m2 g–1, respectively. Experiments were performed in a glass sandbox to simulate the transport and degradation of PCE in the aquifer. The results of the transport tests revealed that the PCE concentrations at the bottom layer was higher than those at the mid and upper layers, and that the surfactant Tween 80 showed its conspicuous mobilization for PCE in the aquifer. As the results of the degradation tests showed, NZVI activity could be promoted by electrokinetics that enhanced the remediation performance of PCE contaminated groundwater by the NZVI reactive barrier. Chlorinated byproducts were not detected during the degradation tests, that is, PCE was completely dechlorinated by NZVI in the reactive barrier. The information collected from this study will be useful for further application of the NZVI reactive barrier system to remediate the aquifers contaminated by the chlorinated solvents.


The slope,concrete slabs and construction joints of Zipingpu concrete face rock-fill dam(CFRD) were obviously damaged during Wenchuan earthquake.At the same time,the strong shock induced deformation of the dam.On the basis of the failure phenomenon of Zipingpu dam,shaking table tests and numerical analysis of CFRD,the failure mechanism and aseismatic performance of CFRD including failure behavior of dam slope,acceleration response of dam crest,stress and deformation of concrete slabs,the seismic deformation of dam,and failure behavior of joints of slabs were discussed.As a result,some aseismatic design methods and measures for CFRD are suggested as follows: the stress of slab at the top of CFRD should be paid attention to,the effect of dam deformation on the additional stress of slab should be considered,and then nail-tied panel measure can increase the seismic stability of dam slope.


The article is devoted to the peculiarities of the culture of modern schoolchildren in conditions of social uncertainty and global «multifactorial turbulence» based on the empirical study of the culture of schoolchildren in the city of Krasnoyarsk. The authors investigate the processes observed in the culture of schoolchildren, caused largely by incomplete knowledge of reality, lack of ideas about the trajectories of the future and the situation of «all kinds». At the same time, it clarifies what is actualized, first of all, in such conditions - the «mainstream» of cultural patterns of behavior and thinking or individual reactions of «common sense» and rational personal actions. The author's hypothesis is expressed about what exactly can become a «fulcrum» that opens up the possibility of getting out of the «ideological impasse» when the «culture of the desired present» collides with socio-political bifurcations in the world. The article presents the results of the conducted empirical research and makes assumptions about the tasks of further research work within the framework of the stated issues.

Boosting is a powerful and thoroughly investigated learning technique that improves the accuracy of any given learning algorithm by weighting training examples and hypotheses. Several authors contributed to the general boosting learning framework with theoretical and experimental results, mainly, or better exclusively, in the propositional learning framework. In this paper, we investigate the applicability of Freund and Schapire's AdaBoost.M1 algorithm to a first order logic weak learner.


Lowering sulfur content of diesel fuel has an important significance on improving the quality of tail gas exhausted from automobiles and protecting the environment.The production of ultra low sulfur diesel mainly depends on hydrodesulfurization and non-hydrodesulfurization technologies.The mechanism of deep hydrodesulfurization and brings forward research gaps needed to be resolved is outlined.The deep hydrodesulfurization of diesel fules requires the decomposition of refractory compounds such as 4,6-dimethyldibenzothiophene(4,6-DMDBT).Design approaches to the catalysts of deep hydrodesulfurization are discussed.New research development in recent years on catalysts and processes of diesel deep hydrodesulfurization are also introduced.Moreover,the non-hydrodesulfurization methods by adsorption,oxidation,or biology are presented.The organic combination of hydrodesulfurization and non-hydrodesulfurization technologies has a promising prospect in the production of ultra low sulfur diesel.


The invention relates to a tank system of a motor vehicle comprising a volume modifying element (11) which is provided in the inner chamber of the fuel tank (1) and which is used to equalize the vapor pressure and said compensation volume is connected to the surrounding area (U). The only connection between the volume modifying element (11) and the surrounding area is formed by a storage unit (8) of the gaseous fuel components and the inner chamber of the fuel tank (1) is connected to the surrounding area (U) by means of a valve unit (7), which is normally open when filling the fuel tank (1) and when exceeding or falling below the pressure limits in the inner chamber of the tank, and is otherwise closed, and the storage unit (8) is connected to said valve unit (7) used for gaseous fuel components. Said volume modifying element (11) and the valve unit (7) are designed in such a way that vehicles which are parked for several days do not undergo "diurnal losses" due to the changes in temperature of the surroundings, due to the fact that the vapour pressure equilibrium in the fuel tank (1) can be maintained by the automatic supply and removal of ambient air in the or from the volume modifying element (11) as long as the valve unit (7) remains closed.


Herein, fluosilicic acid, a by-product generated from the wet process of phosphoric acid, is successfully used to synthesize silica substrate. Then three novel adsorbents calcium silicate hydrates (CSH), Al modified CSH (Al-CSH) and F modified CSH (F-CSH) are synthesized from this silica substrate and used as adsorbents to remove Cr(III). Consequently, the largest surface area and abundant pore structure render Al-CSH the best performance for Cr(III) removal. The combination of characterization (X-ray diffraction, Brunauer–Emmett–Teller, scanning electron microscopy, X-ray photoelectron spectroscopy, and UV–Vis] and kinetic experiments reveal the adsorption of Al-CSH proceeds through an ion-exchange mechanism, which follows pseudo-second-order kinetics and Langmuir adsorption model. Moreover, the obtained Cr-bearing Al-CSH could be converted into an efficient photocatalyst by annealing at 300°C/Air, which shows excellent degradation efficiency of 94% for methylene blue during five cycles. This work proposes a route "waste → adsorbent → catalyst", which is significant for waste utilization and water purification.


Flour dough belongs to a group of materials in which a high degree of plasticity is combined with considerable elasticity. Owing to their great industrial importance, a number of technological investigations have been carried out on these materials (of which unvulcanised rubber is another important example); but the problem of bringing the description of their behaviour within the scope of a general theory of viscosity and elasticity has hardly been tackled. The time during which a stress is applied is as important as the magnitude of the stress in determining how much of the deformation is elastic (recoverable) and how much plastic (non-recoverable). This fact suggests that a formulation based on Maxwell's "time of relaxation" should be of value in this connection. The formulation as Maxwell gave it applies to a true fluid, for which case the relaxation is exponential and for which the rate of dissipation of internal stress is proportional to the stress, the constant of proportionality being the reciprocal of the relaxation time. Thus ─ ds / dt = 1/ t r S, or 1/ t r = ─1/S d S/ dt = d (logeS)/ dt , where S is the shearing stress, and t r the relaxation time.


Joe Steinbicker, P.E., S.E. (joes@ssa engineers.com), is a charter member and past chairman of ACI Committee 551, Tilt Up Concrete Construction. He is also a founding member of the Tilt Up Concrete Association and past member of their Board of Directors. By John Lawson P.E., S.E. and Joe Steinbicker P.E., S.E. Crack Control Measures for Tilt-Up Concrete Panels W hen it comes to enclosing large building volumes, it is hard to beat tilt-up concrete construction for economy and durability. Long considered the mainstay for warehouses and big-box retail, the tilt-up method is now frequently employed for commercial projects, churches, schools and Class A office buildings nationwide. With newer types of occupancies driving attention to aesthetics higher and higher, the importance of minimizing concrete cracking in the site-cast precast wall panels is greater than ever. Tilt-up concrete construction incorporates concrete wall panels that are formed, cast and cured on a ground supported slab at the building site and then tilted into place, one large panel at a time. The individual wall panels are erected around the building's perimeter, separated by vertical joints. Single story occupancies are still most common; however, many buildings are now multiple stories. While many of the features of tilt-up panel construction tend to reduce the potential for developing cracks when compared to conventional concrete construction, the unique method of how the buildings are constructed still requires some special considerations for controlling cracking. The lifting and setting of wall panels, as well as the effects of restrained drying shrinkage, are important items to address to minimize potential wall cracking.

In a recent issue of Critical Research on Religion, Mary Jo Neitz presents a four-cell Locations Matrix created by the two dimensions of the status of the religion studied, as dominant and marginal, and position of the researchers vis-à-vis that religion, as insiders or outsiders. Her subsequent arguments about the influence of researcher standpoint perhaps work in the US setting where religion remains popular. This paper points out difficulties in applying the Matrix in the UK setting where religion is unpopular and uses the patently disinterested nature of much of the research conducted by professional sociologists of religion to retrieve the possibility of objective and value-neutral research.


According to the gear meshing theory, derive the tooth surface equation of orthogonal face gear, establish its mathematical model, create the computer program which simulated the shaping process of orthogonal face gear based on its mathematical model in UG/Open GRIP of UG. Parametric design of involute gear cutter has been created. Shaping process of orthogonal face gear with involute gear cutter is simulated and the parametric model of face gear is generated the Shaping process of face gear is showed in the same time. The radius of pointing and undercutting are calculated by the approximate formula, and measured by the tool of UG. A comparison of the two situations is made to demonstrate the feasibility of the method. It will provide the theoretical basis for TCA and the finite element analysis.


[Objective]To study the neuroprotective effects and mechanism of curcumin on mice with cerebral ischemia and reperfusion by analyzing the changes of NO content,Bcl-2 and Bax protein.[Methods]Kunming male healthy mice(n=180) were divided into sham-operated group(group A),Solvent control group(group B),curcumin treatment group(group C) randomly.After ischemia and reperfusion,all groups were divided into 3 h,6 h,24 h,48 h and 72 h subgroups.The mouse models of focal cerebral ischemia and reperfusion were established by suture method.The neurological score of each group was estimated at 24 h.The histopathologic changes were observed by the HE staining method.The NO level wasdetected by the method of nitric acid reductase.Immunochemistry was used to evaluate the expression level of Bcl-2,Bax.[Results]The neurological score in group B was significantly higher than that of group A.While in group C it was significantly different with group B(P0.05).The content of NO was significantly different between group A and B group at 3 h,6 h and 24 h(P0.05).While there were significant differences between C group and B group at 6 h and 24 h(P0.05).The Bcl-2 and Bax expression were increased,while Bcl-2/Bax was decreased in group B.In group C,Bcl-2 expression was obviously increased,and Bax expression was reduced.[Conclusion]Curcumin has neuroprotective effect on mice with cerebral ischemia and reperfusion.Its mechanism might be that the decreasing of expression of NO content and Bax increasing results in inhibition of Bax protein expression and decreased apoptosis and then lead to reduction of delayed neuronal damage after cerebral ischemia.

Maintaining an accurate and up-to-date database of the location of assets is a challenge, especially in complex logistic processes. In hospitals, intolerable time is lost searching for tools and expensive surgical equipment. Batteries are typically undesirable in tracking devices, as they contribute to a high cost and ecological impact. In this paper, we present a solution for tracking assets in hospitals, based on energy-neutral RF sensors using Bluetooth Low Energy (BLE) tags. We developed a reliable solution based on the inside shielding of closets, preventing the signals to contaminate the RF-critical environments, nor generating or receiving interference from neighboring systems. Measurements show that the proposed solution can energize all spatially dispersed tags within this closet efficiently.


Human vibration arises due to mechanical vibration effect on the human body. Mechanical vibration arises from a tool or powered process, entering the body through the palm and fingers which is known as the hand transmitted vibration. Long-term use of certain portable power tools can result in hand and finger symptoms. This study entails solid modelling of the human arm (up to the elbow) using SOLIDWORKS 2012 and mode shapes analysis ANSYS 14 software. Generating a 3-DOF mathematical model of the arm up to shoulder and calculating the transmissibility and power absorption of vibration from hand to wrist and hand to elbow using MATLAB Simulink software. An experiment is also done in-vehicle dynamic lab by taking six male subjects holding the impact drill in the right hand of 6.5 mm, 8 mm and 12.5 mm in diameter of drill size which was subjected to random vibration targeted on metal alloy, concrete block and wooden block in different postures. The transmissibility is verified in the vehicle dynamic lab using to NI data acquisition card (NI cDAQ-9232), and Lab VIEW 8.6.0. The result shows that transmissibility is higher in HTW than HTE and its increases as per the drill size increase. Also, transmissibility is higher in the head and horizontal direction than in the vertical direction, and transmissibility is higher in stiffer materials like metal and concrete blocks. Thus, transmissibility shows the linear relationship with drill size to be a drill. done in (P1) horizontal (P2) different (i) (aluminium concrete (iii) The laboratory experimental study which was conducted to measure the magnitude of vibration transmission from handle to wrist (HTW) and handle to elbow (HTE) of the dominant right hand-arm of six adult male subjects, while grasping an impact drilling machine with 12.5 mm, 8 mm and 6.5 mm drill diameters subject to z-axis vibration in different materials. This experiment was conducted in three different postures (i) P1 (horizontal) direction, (ii) P2 (vertical) direction and (iii) P3 (over the head).  The transmissibility is higher with horizontal position and over the head position in harder material and larger size drills. The resonance peak occurs at 39 Hz to 40 Hz in both the direction horizontal and vertical positions and sometimes in the third direction over the head peak occur at 29 Hz. It might be caused by the sub height and weight because the over the head portion of drilling is fixed, thus peak varies due to the height of the subject and the feeding force to drill.  It is observed that the transmissibility from HTW is higher than the transmissibility from HTE for all the postures and with all three drill sizes. It shows that when the human hand-arm system is exposed to vibration, transmissibility decreases as the distance from the vibration source increases along the hand-arm, and the risk of hand-arm vibration syndrome is higher at the fingertips, palm, and wrist than at other parts of the system.  The transmissibility is more during drilling on harder materials like concrete blocks and metal plates as it is a hard material to drill and the transmissibility is not much affected by the different dimensions of the human hand-arm of various subjects, it depends upon the grip force, push force

The authors investigated a comprehensive set of predictors of high school completion and years of completed education for youth in the Chicago Longitudinal Study, an ongoing investigation of over 1500 low-income, minority children who grew up on high-poverty neighborhoods. The study sample included 1286 youth for whom educational attainment could be determined by age 20. Predictors were measured from birth to high school from participant surveys and administrative records on educational and family experiences as well as demographic attributes. Results from regression analyses indicated that the model explained 30.4% of the variance in years of completed school. The model also predicted accurately 73.3% of youths' observed high school completion status and 72.6% of their high school graduation status. The strongest predictors of educational attainment were maternal educational attainment, school absences and mobility, grade retention, and youth's educational expectations. Findings indicate that students' expectation and school mobility are targets of intervention that can promote children's educational persistence.

Coastal alpine forests are highly vulnerable to oceanic climate trends, yet these diverse environmental interactions remain poorly understood. We used a multispecies perspective to try to better assess the radial growth response of alpine treeline species within the Northeast Atlantic region of North America to climate variables using bootstrapped correlation analysis. The four species present, black spruce (Picea mariana (Mill.) B.S.P.), white spruce (Picea glauca (Moench) Voss), balsam fir (Abies balsamea (L.) Mill.), and eastern larch (Larix laricina (Du Roi) K. Koch) were sampled in an effort to capture tree–climate sensitivity that is representative of this entire alpine treeline. The climate–growth relationships of spruce trees were comparable with those reported in other Labrador studies, but spring drought sensitivity as reported for coastal northern white spruce trees was not observed. Rather, high levels of precipitation suggest that drought did not limit the radial growth of any of the four spe...


After almost a decade of near dormancy, the Babcock and Wilcox plant in Mt. Vernon, Ind., sprang back to life in the late 1980s to give birth to one of the world`s largest pressure vessels. The vessel, which was completely shop-fabricated and assembled, is 69 ft 3 in. high and 44 ft 5 in. in diameter. With walls of 2-7/8-in.-thick steel, more than 100 nozzles, and a gross weight of 1250 tons, it called for creativity in fabrication and some of the best welding technology and craftsmanship available at the time. This was appropriate for a vessel destined to become a part of some of the most promising new technology in power generation. Known as pressurized fluidized bed combustion (PFBC), the method makes it possible to burn high-sulfur coal while meeting stringent environmental standards. American Electric Power (AEP) installed the completed PFBC module, with 200-MW thermal input, at the Ohio Power Tidd Plant in Brilliant, Ohio. The demonstration plant, which began operating in 1990, was planned to show off the combined-cycle PFBC technology and establish it as a viable alternative to conventional coal-fired plants. The paper describes how the PFBC method works, the fabrication of the pressure vessel, and themore » successful four years at the Tidd Plant.« less


That Russia's real estate market, beginning with housing, has been developed along with Russia's market-oriented economic reforms is a truth that needs no mention. This study considers the development of Russia's urban housing market as observed from several measures by narrowing the focus to the measure of differences in household spending on housing. As a first research step, this paper uses the 2008 data from the Russia Longitudinal Monitoring Survey (RLMS) for the purpose of clarifying the actual status of housing differences in Russia in the 2000s. With the development of the urban housing market and flow of workers into cities as the result of market-oriented economic reforms, inter-generational differences arose and the purchase of residential housing by young households in particular has become difficult. Interest rates on mortgage loans in Russia are still high, and for low income young families, loans are out of reach. Based on these circumstances, the government implemented policies to provide mortgage loan assistance to young families and promote housing purchases by young households. This paper approaches the effects exerted by such housing policies on residential housing purchases and home improvements by young households, the main purpose of which was increasing the volume of housing loans and housing construction, and attempts to look specifically at the housing problems directly confronting each generation, through clarification of the housing reality by generation based on the RLMS. As a result, it was understood based on several measures that housing differences between generations arose and that, depending on those differences, the housing problems faced by each generation varied. This difference in problems was caused by effects that resulted from the fact the timing of residential housing purchases was segmentalized as the result of a systemic transformation. The difference in particular between the generation that was able to remain in and privatize its housing from the Soviet era, and the generation that had to purchase homes through Russia's market economy, is substantial. In terms of its real estate industry, housing construction industry, housing remodeling industry, construction materials industry and rental housing circulation, the development of Russia's unique residential real estate market has occurred in response to the problems confronting each generation. On the other hand, this means the government must devise various housing policies to respond not only to development of the market but also to address each of the housing problems that differ between generations. That is, the government must shift away from a housing policy that emphasized only the promotion of housing purchases and housing construction, and move in the direction of (1) improving circulation of the existing housing stock and promoting systematic expansion of the rental housing market, (2) nurturing housing-related industries that will contribute to the quality aspect of the housing environment and formulating policies to assist this sector, and (3) implementing diverse policy support for not only young households but for each generation. This paper draws this conclusion from the housing demand bracket problem, based on an analysis of the RLMS.


This paper presents two performance improvements on sphere tracing. First, a sphere tracing variant designed to take optimal step sizes near planar surfaces is proposed. We demonstrate how relaxation is used to make this method applicable to sphere tracing arbitrary geometries and compare its performance to classical (by Hart) and relaxed (Keinert et al.) sphere tracing in rendering various scenes. The method is also general in the sense that it can be applied in any scenario that requires the computation of ray-surface intersections. Our second contribution is a multi-resolution rendering strategy that can be used with any sphere tracing variant. By starting from a lower resolution and gradually increasing it, render times can be reduced. CCS Concepts Computing methodologies ! Rendering; Ray tracing;

Michiel's description of it as "the little land scape on canvas with the tempest with the gypsy and soldier."2 Michiel wrote his Notizie c. 1530, when the painting belonged to Gabriele Vendramin. No subject proposed for the Tempest has received unanimous critical approval. It has even been thought, following Creighton Gilbert's proposal, that the Tempest lacks a subject.3 But, while "not subject" can be appropriate in modern art, it is not as likely in the Renaissance. De ciphering the Tempest is further complicated by Giorgione's ambiguous treatment of its polysemous elements. Hence, the painting has a metatextual resonance that encourages a highly personal reception of the work affected by the spectator's knowledge and
