Science and Technology: Traffic Signal Systems: A Review of Current
Technology in the United States
Traffic signal systems have been employed since the early twentieth century
as a method of continuously managing traffic flow and saturation at
intersections and to promote smooth and safe automobile transportation. Due
to the continuous increase of traffic congestion in urban areas, there is a
need for further evaluation and implementation of traffic signal systems.
This study reviews and consolidates information on a wide variety of signal
systems, detection devices and communications components in order to
provide a cogent understanding of current technology in the United States.

Education: Examining Student Character Development Within the Liberal Arts
This study examines issues involving student character development within
the small liberal arts institutional setting. It uses one highly selective
liberal arts institution as a case study and analyzes the effects of its
attributed contributions from various institutional resources within the
context of Astin's input-environment-outcome (I-E-O) model. Data elements
from 356 student participants in their fourth undergraduate year were
utilized and were extracted from merged longitudinal databases that
included matching student responses from the 2004 and 2007 Student
Information Forms (SIF) and the 2008 and 2011 College Senior Surveys (CSS).
Although the results of the study confirm many conventional understandings
regarding student character development, they also raise larger questions
regarding the role and effectiveness of small liberal arts institutional
environments as well as their larger counterparts, in contributing to its
enhancement. Click Here to View Full Article
International Journal of Psychology and Behavioral Sciences: Resiliency and
War Experiences: A Psychometric Study of the Lebanese Adolescent Experience
of War Rana Tayara
If Article 22 of the Universal Declaration of Human Rights, which states
that "Everyone, as a member of society, has the right to social security
and is entitled to realisation, through national effort and international
co-operation and in accordance with the organization and resources of each
State, of the economic, social and cultural rights indispensable for his
dignity and the free development of his personality" is taken as a
fundamental right for each individual to develop a healthy psychological
state, then protecting the mental health of individuals everywhere is a
priority. This priority becomes more critical during conflict, where
psychological well-being is threatened by several traumatic experiences.
This article investigates thepost-traumatic-growth of Lebanese adolescents
after the war in 2006 and its relation to resiliency in a sample of 549
Lebanese Adolescents from four main regions in Lebanon (Beirut, South,
BekaaValley and the North of Lebanon). Click Here to View Full Article
American Journal of Mathematics and Statistics: Constructing Locally Best
Invariant Tests of the Linear Regression Model Using the Density Function
of a Maximal Invariant
In the context of the linear regression model in which some regression
coefficients are of interest and others are purely nuisance parameters, we
derive the density function of a maximal invariant statistic after
eliminating the nuisance parameters by the principle of invariance
argument. This allows the construction of a range of optimal test
statistics including the locally best invariant (LBI) test which is
equivalent to the well-known one-sided t-test. The resultant LBI test is
also found to be uniformly most powerful invariant (UMPI). Click Here to

Food and Public Health: Extraction of Polyphenols and Anthocyanins from the
Jambul (Syzygium cumini) Fruit Peels
In this work, the feasibility of using ultrasound alone and in combination
with other techniques for the extraction of polyphenols and anthocyanins
from jambul (Syzygiumcumini) peels was evaluated. The results were compared
with conventional techniques (agitated bed and Soxhlet extraction
techniques) based on total extract yields, total phenolic and monomeric
anthocyanin concentrations in the extracts and the relative yields of these
compounds. Ultrasound-assisted extraction was more efficient and selective
for the extraction of anthocyanins than both conventional methods. When a
combination of ultrasound and agitated bed extraction was used, a
significant increase in total yields, and both polyphenol and anthocyanin
concentrations was achieved. Click Here to View Full Article
International Journal of Networks and Communications: Effects of
Temperature Variations on Microstrip Antenna
Present paper describes the effects of temperature variations on the
performances of rectangular patch antenna exposed to different
temperatures. The antenna is designed at room temperature 300 0K with
operating frequency 2.45 GHz and bandwidth 0.0518 GHz, return loss -21.83
dB and impedance 50 ohms are observed. When the temperature is decreased
the value of frequency, bandwidth and impedance reduce up to 2.01 GHz,
0.0272 GHz and 35.95 ohm respectively and return loss of antenna is
increased up to -13.46 dB. However if temperature is increased the value of
frequency, bandwidth and impedance of antenna reduce up to 1.96 GHz, 0.0272
GHz, and 35.05 ohm respectively and return loss of antenna is increase up
to -12.61 dB. Bandwidth of the antenna shows a negligible change while
impedance reduces when temperature rise. Click Here to View Full Article
Journal of Microbiology Research: In vitro Antimicrobial Activities of
Endophytic Fungi Isolates from Medicinal Tree - Melia azedarach L.
Endophytes, found ubiquitous in all plant species in the world, contribute
to their host plants by producing plethora of substances that provide
protection and ultimately survival value to the plant. Many researchers
have proven that endophyte is a new and potential source of novel natural
products for exploitation in modern medicine, agriculture and industry. So
far, a great number of novel natural products possessing antimicrobial
activities have been isolated from endophytes. These are endophytic
microorganisms that inhabit the intercellular spaces of plant tissues and
are often responsible for antimicrobial production. Click Here to View Full

Clinical Medicine and Diagnostics: Serum HER-2/neu Reference Intervals in a
Multiethnic Malaysian Population
Amplification of HER-2/neu gene in breast cancer carries poor clinical
prognosis, but its detection is important in managing the disease.
Immunohistochemistry (IHC) is used traditionally to assess the HER-2/neu
status, but this technique requires high quality tissue samples. Serum HER-
2/neu provides an alternative non invasive option to the assessment of Her-
2/neu status. To establish the reference range values of serum HER-2/neu
concentration in multiethnic Malaysian women and to evaluate the
association between serum HER-2/neu with the clinicopathological
parameters. Click Here to View Full Article
International Journal of Brain and Cognitive Sciences: Absence of
Placeholders Abolishes Exogenous Attention Effect in a Peripheral Cueing
Procedure
Most studies of exogenous visuospatial attention use placeholders
indicating the regions where the stimuli appear on the screen. Preliminary
results from our laboratory provided evidence that the attentional effect
is more frequently observed when placeholders are used in these
experimental procedures. Four experiments were carried out. Experiment 1
aimed at confirming the finding that the attentional effect of a spatially
non-informative cue (S1) observed in the presence of placeholders
disappears in their absence. The results confirmed this finding.
Experiments 2, 3, and 4 examined several possible processes that could
explain this finding. Click Here to View Full Article
International Journal of Construction Engineering and Management: An
Integrated Approach for Project Management of the Wooden Constructions
Using the CNC Production
Contribution deals with options of innovation the production process of
wooden structures from design to production itself, including the
establishment of preconditions for seamless installation on site. An
essential step is the introduction of CNC (Computer Numerical Control)
production which paves the way for more effective management of the
resources which enter into the production, as well as the opportunity to
qualitatively higher level of the process controls of manufacturing of the
wooden houses. This paper presents the proposed measures, at the same time
their anticipated impact on the production of wooden houses. These measures
have a major impact on the return an investment throughout the
implementation of CNC manufacturing. Click Here to View Full Article
