EXISTENCE OF THREE POSITIVE SOLUTIONS FOR AN m-POINT BOUNDARY-VALUE PROBLEM ON TIME SCALES
(TEXAS STATE UNIV, 601 UNIVERSTITY DRIVE, SAN MARCOS, TX 78666 USA, 2013)
We study an m-point boundary-value problem on times scales. By using a fixed point theorem, we prove the existence of at least three positive solutions, under suitable growth conditions imposed on the nonlinear term. An ...
Performance comparison of ieee 802.11p and IEEE 802.11b for vehicle-to-vehicle communications in highway, rural, and urban areas
(2013)
Communication between vehicles has recently been a popular research topic. Generally, the Vehicle-to-Vehicle (V2V), Vehicle-to-Infrastructure (V2I), and Infrastructure-to-Infrastructure (I2I) communications applications ...
Recovery of Manganese from Spent Batteries Using Activated Carbon Powder as Reductant in Sulfuric Acid Solution
(ASIAN JOURNAL OF CHEMISTRY, 11/100 RAJENDRA NAGAR, SECTOR 3,, SAHIBABAD 201 005, GHAZIABAD, INDIA, 2013)
Recovery of manganese from spent batteries was investigated using activated carbon powder as a reducing agent in sulfuric acid solution. The effects of four different leaching parameters (sulfuric acid concentration, amount ...
Dynamics in the Diffusion and Institutionalization of Site-Based Management Reform in the United States of America
(Eskişehir Osmangazi Üniversitesi, 2013)
This study is examined research question: “How does the
diffusion of SBM over time and space resemble the broader
social dynamics associated with diffusion of educational policy

A model for the recombination and radiative lifetime of trions and biexcitons in spherically shaped semiconductor nanocrystals
(AIP Publishing1305 WALT WHITMAN RD, STE 300, MELVILLE, NY 11747-4501, 2013)
In this letter, we propose a different model to determine the recombination oscillator strength of trions and biexcitons for bound and unbound cases in the effective mass approximation. The validity of our model has been ...
Influence of admixtures on the properties of alkali-activated slag mortars subjected to different curing conditions
(ELSEVIER SCI LTD, 2013)
This paper presents the influence of shrinkage-reducing (SHR) and superplasticizing and set-retarding
admixtures (SSRe) on the properties of slag pastes and mortars activated by liquid sodium silicate with
different ...
Dual effectiveness of freezing-thawing and sulfate attack on high-volume slag-incorporated ECC
(ELSEVIER SCI LTD, 2013)
This study investigated the dual effect of freeze–thaw cycles with sodium sulfate solution on the performance of non-air-entrained Engineering Cementitious Composites (ECCs) with high volumes of slag. ECC
specimens ...
Theoretical and Experimental Analysis of Wave Impact Pressures on Curved Seawalls
(SPRINGER HEIDELBERG, 2013)
Experimental model tests were performed in a
wave flume with regular waves to measure the magnitude and
distribution of impact pressures caused by breaking waves on
a curved seawall model having different radii of ...
Thermal conductivity, compressive strength and ultrasonic wave velocity of cementitious composite containing waste PET lightweight aggregate (WPLA)
(ELSEVIER SCI LTD, 2013)
In this study, the influence of waste PET as lightweight aggregate (WPLA) replacement with conventional
aggregate, on thermal conductivity, unit weight and compressive strength properties of concrete composite was ...
Taking advantage of a diverse set of efficient production schedules: A two-step approach for scheduling with side concerns
(PERGAMON-ELSEVIER SCIENCE, 2013)
In many practical scheduling problems, the concerns of the decision-maker may not be all known in
advance and therefore may not be included in the initial problem definition as an objective function
and/or as constraints. ...
