Flexure of Thick Plates Resting on Elastic Foundation Using Two-Variable Refined Plate Theory
Authors: Rouzegar Jafar , Sharifpoor Reza Abdoli 
Published: August 2015

AbstractThe two-variable refined plate theory is used in this paper for the analysis of thick plates resting on elastic foundation. This theory contains only two unknown parameters and predicts parabolic variation of transverse shear stresses. It satisfies the zero traction on the plate surfaces without using shear correction factor. Using the principle of minimum potential energy, the governing equations for simply supported rectangular plates resting on Winkler elastic foundation are obtained. The Navier method is adopted for solution of obtained coupled governing equations, and several benchmark problems under various loading conditions are solved by present theory. The comparison of obtained results with other common theories shows the excellent efficiency of this theory in modeling thick plates resting on elastic foundation. Also, the effect of foundation modulus, plate thickness and type of loading are studied and the results show that the deflections are decreased by increasing the foundation modulus and plate thickness

Published: August 2015

Abstract
In recent times, the concept of hard turning has gained awareness in metal cutting as it can apparently replace the traditional process cycle of turning, heat treating, and finish grinding for assembly of hard, wear-resistant steel parts. The major apprehension in hard turning is the tool vibration, which affects the surface finish of the work piece, has to be controlled and monitored. In order to control tool vibration in metal cutting, a magnetorheological fluid damper which has received great attention in suppressing tool vibration was developed and used. Also an attempt has been made in this study to monitor tool vibration using the skewness and kurtosis parameters of acoustic emission (AE) signal for the tool holder with and without magnetorheological damper. Cutting experiments were conducted to arrive at a set of operating parameters that can offer better damping characteristics to minimize tool vibration during turning of AISI4340 steel of 46 HRC using hard metal insert with sculptured rake face. From the results, it was observed that the presence of magnetorheological damper during hard turning reduces tool vibration and there exist a strong relationship between tool vibration and acoustic emission (AERMS) signals to monitor tool condition. This work provides momentous understanding on the usage of magnetorheological damper and AE sensor to control and monitor the tool condition during turning of hardened AISI4340 steel

Authors: Kofjač Davorin , Bavec Blaž , Škraba Andrej 
Published: August 2015

Abstract
Background and Purpose: In a complex strictly hierarchical organizational structure, undesired oscillations may occur, which have not yet been adequately addressed. Therefore, parameter values, which define fluctuations and transitions from one state to another, need to be optimized to prevent oscillations and to keep parameter values between lower and upper bounds. The objective was to develop a simulation model of hierarchical organizational structure as a web application to help in solving the aforementioned problem.
Design/Methodology/Approach: The hierarchical structure was modeled according to the principles of System Dynamics. The problem of the undesired oscillatory behavior was addressed with deterministic finite automata, while the flow parameter values were optimized with genetic algorithms. These principles were implemented as a web application with JavaScript/ECMAScript.
Results: Genetic algorithms were tested against well-known instances of problems for which the optimal analytical values were found. Deterministic finite automata was verified and validated via a three-state hierarchical organizational model, successfully preventing the oscillatory behavior of the structure.
Conclusion: The results indicate that the hierarchical organizational model, genetic algorithms and deterministic finite automata have been successfully implemented with JavaScript as a web application that can be used on mobile devices. The objective of the paper was to optimize the flow parameter values in the hierarchical organizational model with genetic algorithms and finite automata. The web application was successfully used on a three-state hierarchical organizational structure, where the optimal flow parameter values were determined and undesired oscillatory behavior was prevented. Therefore, we have provided a decision support system for determination of quality restructuring strategies.
A Statistical Model for Shutdowns due to Air Quality Control for a Copper Production Decision Support System
Authors: Aboura Khalid 
Published: August 2015

Abstract
Background: In the mid-1990s, a decision support system for copper production was developed for one of the largest mining companies in Australia. The research was conducted by scientists from the largest Australian research center and involved the use of simulation to analyze options to increase production of a copper production facility.
Objectives: We describe a statistical model for shutdowns due to air quality control and some of the data analysis conducted during the simulation project. We point to the fact that the simulation was a sophisticated exercise that consisted of many modules and the statistical model for shutdowns was essential for valid simulation runs.
Method: The statistical model made use of a full year of data on daily downtimes and used a combination of techniques to generate replications of the data.
Results: The study was conducted with a high level of cooperation between the scientists and the mining company. This contributed to the development of accurate estimates for input into a support system with an EXCEL based interface.
Conclusion: The environmental conditions affected greatly the operations of the production facility. A good statistical model was essential for the successful simulation and the high budget expansion decision that ensued.
Community Frames of Migration: The Path from Seaca to Spain
Authors: Deliu Alexandra 
Published: August 2015

Abstract
Transnational migration is a vast social phenomenon that has become a valid option for many Romanians since 1989. Romania is an emigration country and the favourite destinations of its citizens are Italy and Spain. This is the context in which I present my work, which focuses on the formation of transnational migration patterns from a village in the southern region of Romania. The data were generated during field research conducted in August 2012, and the empirical material consisted of field notes and interview transcripts corresponding to recorded conversations with local migrants, authority representatives and people without migration experience. In this particular community, two patterns of migration were identified, for which variables such as ethnicity (Roma/Romanian) and religious orientation (Orthodoxy/Adventism) appear to have explanatory power. My inquiry takes as its starting point the identification of this variety of migration patterns and concentrates on analysing them in the regional and national contexts based on the scholarly framework provided by network theory. Two major differences exist between them: the time frame of living and working abroad (clearly demarcated as three months, six months or indefinite) and the nature of the work environment (departures based on a work contract between the migrant and a company located at the destination and departures accompanied by uncertainty regarding workplace concerns upon arrival). Making sense of these life strategies and their local configurations are the objectives of this paper.
Social Work or Relief Work? A Crisis in Professional Social Work
Authors: Adhikari Harasankar 
Published: August 2015

Abstract
Social work is a sharing and caring profession based on scientific methods. This problem solving profession makes people self-reliant and self-dependent when he/she is in any sorts of crises. Thus, it differs from relief work, social services or social welfare delivered during emergence crises. This paper examined the application of professional social work as relief work, which did not bring any change among the beneficiaries; rather it set their mind as opportunist. For this purpose, the programme sponsored by the government of India and implemented by nongovernmental organizations for rehabilitation of the street children (i.e., pavements and slums dwellers, children of sex workers, and so forth) of Metro cities like Kolkata had priority. This evaluative study assessed the progress and changes among 500 street children who were the beneficiaries for 10 years of the programme, selected according to their parental residents/occupation through stratified sampling. Interviews, case studies and group interaction were used to collect data on various aspects, i.e. personal background, education, and occupation of these children. It revealed that after almost 10 years of services, the problem of children was static. Firstly, service delivery system was as relief work. The methods of social work were not implied while the professionals were in implementation. On the other hand, the scope of monitoring and evaluation of the programme by government was suspended due to several reasons. Definitely, the politicalization in human development would be restricted. The problems of suffering would be root out and it should not be a continued process.
Soil salinity effects on phenological traits, plant height and seed yield in rapeseed genotypes
Authors: Rameeh Valiollah , Gerami Mahyar 
Published: August 2015

Abstract
Among the various abiotic stresses limiting the crop production, salinity stress is the most important problem, which needs to be addressed and answered straight away. A pot experiment was carried out with rapeseed breeding lines in order to study the effects of salinity stress on phenological traits, plant height and seed yield of rapeseed. A factorial experiment was applied for evaluating the eight rapeseed genotypes under three salinity levels including 0, 6 and 12 dS m-1 taking NaCl:CaCl2 in the ratio of 1:1, which were equal to 42.8 mM and 85.7 mM, respectively. The results of analysis of the variance revealed significant variations among different salinity levels, genotypes and interaction effects of salinity levels × genotypes for days to flowering, days to end of flowering, days to maturity, plant height and seed yield. Due to increasing salinity levels, days to flowering, days to end of flowering and days to maturity were shortened. Although with increasing salinity levels plant height and seed yield of the genotypes were decreased but the ranks of genotypes were different in 0, 6 and 12 dS m-1 salinity levels. The genotypes had significant genetic differences for the traits and the increments of differences also were decreased due to increasing salinity levels. The genotypes had high amount of genetic coefficient variation for days to flowering and seed yield, therefore the efficiency of selection of these two traits will be high. The genotypes including KRN1, LRT1 and Hyola401 with high amounts of seed yield in all salinity levels were considered as tolerant genotypes.
Physical and chemical properties of selected soils from the surroundings of the Magura National Park (southern Poland) / Właściwości fizykochemiczne i chemiczne wybranych gleb z otoczenia Magurskiego Parku Narodowego

Abstract
The aim of the study was to investigate the basic physicochemical and chemical properties of six soil profiles located in the surrounding of the Magura National Park (S Poland). The type of agricultural use and terrain relief were the main criteria for choosing the soil profiles. The research identified the following types or sub-types of soils: Eutric Gleysols, Dystric Cambisols, Eutric Cambisols, Gleyic Luvisols. The analyzed soils were characterized by particle size distribution of a silty clay or silt. They were usually strongly acidified as evidenced by low pH (in 1M KCl, values ranged from 3.8 to 5.8), high values of hydrolytic acidity (from 0.8 up to 10 cmol(+)·kg-1) and exchangeable acidity (from 0.05 to 4.05 cmol(+)·kg-1), as well as remarkable concentration of exchangeable aluminum (from 0 to 3.96 cmol(+)·kg-1). The organic carbon content in studied profiles did not exceed (except from gley soil in profile ) 30 g·kg-1 and it decreased along with the depth to several g·kg-1 in parent rock. These soils were characterized by not very high content of total nitrogen (from 0.3 to 9.39 g·kg-1) and low available phosphorus concentration (from 3.5 to 90.3 mg P2O5·kg-1). Contents of available potassium (from 82 to 570 mg K2O·kg-1) and magnesium (from 33 to 412 mg Mg·kg-1) allow for classifying the profiles studied as soils moderately or highly abundant in K and Mg. The highest levels of biogenic elements were determined in surface horizons. Studied soils were characterized by high total sorption capacity (T) - from 7.04 to 63.4 cmol(+)·kg-1. Sum of base cations (S) reached values from 3.01 to 61.2 cmol(+)·kg-1, which resulted in high base saturation (V) (maximum over 96%). The base saturations in profiles of the soils increased along with depth.
A Mechanistic Studies of Mn(II) Catalyzed Oxidation of a Gabapentin by Peroxomonosulphate in Aqueous Alkaline Medium
Authors: Asiri Abdullah M. , Parwaz Khan Aftab Aslam , Khan Anish 
Published: August 2015

Abstract
A mechanistic approach to the influence of Mn(II) catalyzed
oxidative deamination of an anti-convulsant drug [GP] by
peroxomonosulphate (PMS) at a constant ionic strength of
1.0 mol dm
–3 have been studied,
spectrophotometrically. The reaction shows first order dependence on
[PMS] and [Mn(II)] and apparent less than unit order dependence
each in [GP] and alkali concentrations. Influence of dielectric
constant and ionic strength of the medium on the reaction rate have
been evaluated. It was observed that the added sulphate ion, the
reduction product of the oxidant, had insignificant effect on the
reaction rate. The reaction stoichiometry and oxidation products
deprotonated GP, SO4
2− and MnO2 have
been identified and a suitable mechanism has been proposed. The
reaction fails to initiate polymerization in the presence of
acrylonitrile under the experimental conditions employed. In
a composite equilibrium step, deprotanated GP binds to catalyst and
form a complex C that subsequently decomposes with oxidant to yield
the products. Investigations of the reaction at different temperatures
allowed the determination of the activation parameters and a tentative
reaction mechanism in good consistency with the kinetic results is discussed.
Ultrafast Dynamics of the Indoline Dye D149 on Mesoporous ZnO and Al2O3 Thin Films
Authors: Flender Oliver , Lohse Peter W. , Du Juan , Oekermann Torsten , Scholz Mirko , Oum Kawon , Lenzer Thomas 
Published: August 2015

Abstract
Ultrafast photoinduced electron injection and subsequent relaxation
steps of the indoline dye D149 were investigated for
mesoporous thin films using pump–supercontinuum probe (PSCP)
transient absorption spectroscopy in the range
370–770 nm. Three types of mesoporous ZnO layers
were compared: Electrodeposited ZnO thin films prepared by
using the structure-directing agents (1) Eosin Y (EY) and (2) Coumarin
343 (C343), which are known to produce ZnO layers of different
morphology; and (3) mesoporous ZnO thin films consisting of
sintered nanoparticles with a diameter of 20 nm. As
a reference system, we used a “non-injecting” mesoporous thin film
with large band-gap, consisting of Al2O3 nanoparticles
with a diameter of 50 nm. On all ZnO thin films,
D149 efficiently injects electrons. We observed two
components, a dominant one with τ ≤ 70 fs
(time-resolution-limited) and a slower one with a time constant of
250–350 fs. Fast initial charge separation is also
consistent with the immediate appearance of oscillatory structure due
to a change in refractive index of ZnO upon electron
injection. For all ZnO thin films, we observe a transient shift
of the spectra with a time constant of ca. 20 ps which is
assigned to a transient Stark effect (= electrochromism). The
S0 → S1 absorption band of D149 is
shifted due to the build-up of a local electric field between dye
radical cations and ZnO conduction band electrons. On longer
timescales, step-scan FTIR spectroscopy revealed a slightly faster
cation-electron recombination on ZnO/C343 than on
ZnO/EY thin films. On Al2O3, metastable close
cation-electron pairs are formed initially which recombine afterwards,
and no transient Stark effect is observed. Complementary PSCP
experiments on D149 in the ionic liquid
[C2mim]+ [N(CN)2]
–
show that D149 is
ideally suited for solar cell applications because of its long
S1 lifetime of 590 ps. In addition, biphasic
solvation dynamics are observed in this IL with a subpicosecond
component and a much slower component related to the viscosity of the
IL which is well described by a stretched exponential.
Proficiency of Professional Document Examiners in Writer Identification
Authors: Kam M , Wetstein J , Conn R 
Published: August 2015

Abstract
A comprehensive writer identification test was designed and administered to a group of professional document examiners and to a control group of nonprofessionals. The professional group consisted of seven document examiners from the Federal Bureau of Investigation. The control group consisted of ten graduate students in the areas of engineering and business. The main finding is that the professional document examiners performed significantly better than the members of the control group. The hypothesis that professionals and nonprofessionals are equally proficient in performing writer identification was found via the Kruskal-Wallis test to have probability of less than 0.001. These findings give indication that handwriting identification expertise indeed exists, and calls into question the conclusions of previous studies in this area.
Restoring Texts of Typewriter Ribbons: A Reliability Study of the RAW-1 Ribbon Analysis Workstation
Authors: Hunton RK , Puckett JT 
Published: August 2015

Abstract
The ribbon analysis workstation (RAW-1) is a computer driven electro-mechanical device designed to enable specialists in questioned documents to transcribe and analyze any of a wide range of multi-row, single-strike, carbon film ribbons. The time consuming method of manually reading a single-strike ribbon makes the introduction of the RAW-1 a unique labor saving instrument. This study examines the accuracy of the RAW-1 in reproducing an accurate transcription of an original text from a carbon film ribbon. Ten single-strike ribbons, with a predetermined text of ten thousand words, were processed on the RAW-1. The texts from the ribbons were then compared to the printout from the RAW-1 for accuracy and repeatability.
“Tarasoff” Defendants: Social Justice or Ethical Decay?
Authors: Leong GB , Eth S , Silva JA 
Published: August 2015

Abstract
In 1976, the California Supreme Court ruled in Tarasoff v. Regents of the University of California that a duty to protect arises when a psychotherapist's patient poses a serious danger of physical harm to an identifiable third party. Discharging this duty by the issuance of a warning breaches the confidentiality of the psychotherapist-patient relationship. However, the potential benefit to society offsets the possible harm caused by the breach of confidentiality. Until recently, such warnings have served little purpose outside of possibly preventing harm. However, the cumulative effect of three recent California Supreme Court cases has been to permit the use of these confidentiality breaches in criminal proceedings to fulfill prosecutorial goals. Nonetheless, the cost of achieving social justice may be at the expense of other important ethical values for both the psychotherapeutic professions and society in general.
A Method for Establishing the Age of Subadults
Authors: Pfau RO , Sciulli PW 
Published: August 2015

Abstract
Accurate estimates of age-at-death of subadult human skeletal remains are limited because of the dearth of information on the covariance among reliable indicators in recent samples of children. To obtain these kinds of data, namely patterns of maturation among dental development, epiphyseal union, and long bone growth, we focused on a radiographic method using recently deceased children.
A total of 183 subadult cadavers were examined using X-radiographs of the six long bones and the mandibular dentition with measurements and evaluations thereof.
The results of this study show that cadaver samples can relatively inexpensively, provide accurate and precise information on the covariance of subadult age indicators and thus can contribute to the formation of age standards for population lacking such data.
Drift Trajectories of a Floating Human Body Simulated in a Hydraulic Model of Puget Sound
Authors: Ebbesmeyer CC , Haglund WD 
Published: August 2015

Abstract
After a young man jumped off a 221-foot (67 meters) high bridge, the drift of the body that beached 20 miles (32 km) away at Alki Point in Seattle, Washington was simulated with a hydraulic model. Simulations for the appropriate time period were performed using a small floating bead to represent the body in the hydraulic model at the University of Washington. Bead movements were videotaped and transferred to Computer Aided Drafting (AutoCAD®) charts on a personal computer. Because of strong tidal currents in the narrow passage under the bridge (The Narrows near Tacoma, WA), small changes in the time of the jump (± 30 minutes) made large differences in the distance the body traveled (30 miles; 48 km).
Hydraulic and other types of oceanographic models may be located by contacting technical experts known as physical oceanographers at local universities, and can be utilized to demonstrate trajectories of floating objects and the time required to arrive at selected locations. Potential applications for forensic death investigators include: to be able to set geographic and time limits for searches; determine potential origin of remains found floating or beached; and confirm and correlate information regarding entry into the water and sightings of remains.
Sudden Death Due to Coronary Artery Anomalies: A Case Report and Clinical Review
Authors: Rao C , Rao V , Heggtveit HA , King DL 
Published: August 2015

Abstract
Congenital anomalies of the coronary arteries are relatively uncommon conditions with an incidence of approximately 2% in the adult population. Although less common than acquired coronary artery disease, these anomalies may be associated with myocardial ischemia and its consequences; angina, arrhythmia, infarction, and sudden death. A 21-year-old female patient with no significant prior medical history was found dead at home. Postmortem examination revealed high take-off of the right coronary artery with acute downward angulation of the proximal right coronary artery and acute downward angulation of the left main coronary artery. Microscopic examination revealed global myocardial ischemia consistent with a terminal ventricular dysrhythmia. There was no evidence of any other disease processes. Detailed toxicological investigation was negative. The Regional Forensic Pathology Unit experience with sudden death due to congenital coronary artery anomalies is presented along with a review of the current literature.
