Abstract: In this paper will be discussed two coin´s sides
of crisis scenarios dynamics. On the one's side is negative role
of subsidiary scenario branches in its compactness weakening
by means unduly chaotic atomizing, having many interactive
feedbacks cases, increasing a value of a complexity here.
This negative role reflects the complexity of use cases, weakening
leader compliancy, which brings something as a ´readiness
for controlling capabilities provision´. Leader´s dissatisfaction has
zero compliancy, but factual it is a ´crossbar´ (interface in fact)
between planning and executing use cases. On the other side of this
coin, an advantage of rich scenarios embranchment is possible to see
in a support of response awareness, readiness, preparedness,
adaptability, creativity and flexibility. Here rich scenarios
embranchment contributes to the steadiness and resistance of scenario
mission actors. These all will be presented in live power-points
´Blazons´, modelled via DYVELOP (Dynamic Vector Logistics
of Processes) on the Conference.
Abstract: Keyboard is the most important equipment for computer tasks. However, improper design of keyboard would cause some symptoms like ulnar and/or radial deviations. The research goal of this study was to investigate the optimal size(s) of keycaps to increase efficiency. As shown in the questionnaire pre-study with 49 participants aged from 20 to 44, the most commonly used keyboards were 101-key standard keyboards. Most of the keycap sizes (W×L) were 1.3×1.5 cm and 1.5×1.5 cm. The fingertip breadths of most participants were 1.2 cm. Therefore, in the main study with 18 participants, a standard keyboard with each set of the 3-sized (1.2×1.4 cm, 1.3×1.5 cm, and 1.5×1.5 cm) keycaps were used to investigate their typing efficiency, respectively. The results revealed that the differences between the operating times for using 1.3×1.5 cm and 1.2×1.4 cm keycaps was insignificant while operating times for using 1.5×1.5cm keycaps were significantly longer than for using 1.2×1.4 cm or 1.3×1.5 cm, respectively. As for typing error rate, there was no significant difference.
Abstract: We used 24 Ile de France lambs, weighing between 15 and 32 kg (BW). Treatments were supplemented with concentrate: “in nature” sugarcane (IN), sugarcane hydrolyzed using 0.6% calcium oxide (CaO) under aerobic condition (AER), and sugarcane hydrolyzed using 0.6% CaO under anaerobic condition (ANA), constituting a completely randomized design with eight repetitions per treatment. Lambs were housed in individual stalls and fed into the through, allowing 10% of leftovers. Lambs were slaughtered when body weight reached 32 kg. The following parameters were determined on Longissimu lumborum muscle of hot and cold carcasses: pH and color, 45 minutes and 24 hours after slaughtering. Qualitative analysis of the meat were performed in the loins, water-holding capacity (WHC), cooking loss (CL), and shear force (SF). We used a completely randomized design with three treatments and eight repetitions. Means were compared by Tukey test at 5% significance. A higher value for redness (a*) 45 minutes after slaughter (10.48) were found for lambs fed hydrolyzed under anaerobic conditions sugarcane. The other qualitative characteristics of meat were not affected by treatments (P >0.05). The comparison of meat quality resulting from the treatments shows that it is possible to feed in nature sugarcane to lambs, thus waiving hydrolyses process and the spending with alkalizing agent.

Abstract: This research studies the electroplating of zinc coating
in the zinc chloride bath mixed with supercritical CO2. The sodium
fluoride (NaF) was used as the bath additive to change the structure
and property of the coating, and therefore the roughness and corrosion
resistance of the zinc coating was investigated. The surface
characterization was performed using optical microscope (OM), X-ray
diffractometer (XRD), and α-step profilometer. Moreover, the
potentiodynamic polarization measurement in 3% NaCl solution was
employed in the corrosion resistance evaluation. Because of the
emulsification of the electrolyte mixed in Sc-CO2, the electroplated
zinc produced the coating with smoother surface, smaller grain, better
throwing power and higher corrosion resistance. The main role played
by the NaF was to reduce the coating’s roughness and grain size. In
other words, the CO2 mixed with the electrolyte under the supercritical
condition performed the similar function as brighter and leveler in zinc
electroplating to enhance the throwing power and corrosion resistance
of the coating.
Abstract: This numerical study aims to develop a coupled,
passive and active control strategy of the flow around a cylinder of
diameter D, and Re=4000. The strategy consists to put a cylindrical
rod in front of a deforming cylinder. The quasi- elliptical deformation
of cylinder follow a sinusoidal law in order to reduce the drag force.
To analyze the evolution of unsteady vortices, the Large Eddy
Simulation approach is used in this 2D simulation, carried out using
ANSYS – Fluent. The movement of deformation is reproduced using
an internal subroutine, introduced in the form of a User Defined
Function UDF. Two diameters of the rod were tested for a rod placed
at a distance L = 3 ×d, with an amplitudes of deformation A = 5%, A
= 25% and A = 50% of the cylinder diameter, the frequency of
deformation take the values fd = 1fn, 5fn and 8fn, which fn
represents the naturel vortex shedding frequency. The results show
substantial changes in the flow behavior and for a rod of 6mm (1%
D) with amplitude A = 25%, and with a 2fn frequency, drag
reduction of 60% was recorded.
Abstract: This paper describes a blind algorithm, which is
compared with two another algorithms proposed in the literature,
for estimating of the minimum phase channel parameters. In order to
identify blindly the impulse response of these channels, we have used
Higher Order Statistics (HOS) to build our algorithm. The simulation
results in noisy environment, demonstrate that the proposed method
could estimate the phase and magnitude with high accuracy of these
channels blindly and without any information about the input, except
that the input excitation is identically and independent distribute
(i.i.d) and non-Gaussian.
Abstract: The effect of reliability on life-cycle cost, including
initial and maintenance cost of a system is studied. The failure
probability of a component is used to calculate the average
maintenance cost during the operation cycle of the component. The
standard deviation of the life-cycle cost is also calculated as an error
measure for the average life-cycle cost. As a numerical example, the
model is used to study the average life-cycle cost of an electric motor.
Abstract: The aims of this research are to broaden the study on the relationship between emotional intelligence and counterproductive work behavior (CWB). The study sample consisted in 441 Romanian employees from companies all over the country. Data has been collected through web surveys and processed with SPSS. The results indicated an average correlation between the two constructs and their sub variables, employees with a high level of emotional intelligence tend to be less aggressive. In addition, labeling was considered an individual difference which has the power to influence the level of employee aggression. A regression model was used to underline the importance of emotional intelligence together with labeling as predictors of CWB. Results have shown that this regression model enforces the assumption that labeling and emotional intelligence, taken together, predict CWB. Employees, who label themselves as victims and have a low degree of emotional intelligence, have a higher level of CWB.
Abstract: This article deals with a new approach to the airport
emergency plans, which are the basic documents and manuals for
dealing with events with impact on safety or security. The article
describes the identified parts in which the current airport emergency
plans do not fulfill their role and which should therefore be
considered in the creation of corrective measures. All these issues
have been identified at airports in the Czech Republic and confirmed
at airports in neighboring countries.
Abstract: Lawsone is a pigment that occurs naturally in plants.
It has been used as a skin and hair dye for a long time. Moreover, its
different biological activities have been reported. The present study
focused on the effect of lawsone on a plant cell model represented by
tobacco BY-2 cell suspension culture, which is used as a model
comparable with the HeLa cells. It has been shown that lawsone
inhibits the cell growth in the concentration-dependent manner. In
addition, changes in DNA methylation level have been determined.
We observed decreasing level of DNA methylation in the presence of
increasing concentrations of lawsone. These results were
accompanied with overproduction of reactive oxygen species (ROS).
Since epigenetic modifications can be caused by different stress
factors, there could be a connection between the changes in the level
of DNA methylation and ROS production caused by lawsone.
Abstract: The purpose of this paper was to examine views of
secondary school science teachers about purposes to use practical
works in school science. The instrument to survey consisted eighteen
items, which were categorized into four components as follows:
‘Scientific inquiry’, ‘Scientific knowledge’, ‘Science-related attitude’,
and ‘STS (science-technology-society)’. Subjects were 152 secondary
school science teachers (male 70 and female 82; middle school 50 and
high school 102), who are teaching in 42 schools of 8 provinces. On
the survey, science teachers were asked to answer on 5-point Lickert
scale (from 1 to 5) how they thought of using practical works on
purposes with domains of science objectives in school. They had
positive views about using practical works for improving scientific
inquiry process skills, science-related attitudes, and perceptions about
STS literacy, and acquiring scientific knowledge. They would have the
most willingness of using practical works for ‘Scientific Inquiry’
among domains of science objectives in school.

Abstract: Ni-based catalysts with different amounts of Na as
promoter from 2 to 6 wt % were prepared by solution combustion
method. The catalytic activity was investigated in syngas methanation
reaction. Carbon oxides conversion and methane selectivity are greatly
influenced by sodium loading. Adding 2 wt% Na remarkably improves
catalytic activity and long-term stability, attributed to its smaller mean
NiO particle size, better distribution, and milder metal-support
interaction. However, excess addition of Na results in deactivation
distinctly due to the blockage of active sites.

Abstract: In this paper, the numerical solution of optimal control problem (OCP) for systems governed by Volterra integro-differential
(VID) equation is considered. The method is developed by means
of the Legendre wavelet approximation and collocation method. The
properties of Legendre wavelet together with Gaussian integration
method are utilized to reduce the problem to the solution of nonlinear
programming one. Some numerical examples are given to confirm the
accuracy and ease of implementation of the method.
Abstract: In this paper, Semi-orthogonal B-spline scaling
functions and wavelets and their dual functions are presented
to approximate the solutions of integro-differential equations.The
B-spline scaling functions and wavelets, their properties and the
operational matrices of derivative for this function are presented to
reduce the solution of integro-differential equations to the solution of
algebraic equations. Here we compute B-spline scaling functions of
degree 4 and their dual, then we will show that by using them we have
better approximation results for the solution of integro-differential
equations in comparison with less degrees of scaling functions
Abstract: In industrial environments, the heat exchanger is a
necessary component to any strategy of energy conversion. Much of
thermal energy used in industrial processes passes at least one times
by a heat exchanger, and methods systems recovering thermal
energy.
This survey paper tries to presents in a systemic way an sample
control of a heat exchanger by comparison between three controllers
LQR (linear quadratic regulator), PID (proportional, integrator and
derivate) and Pole Placement. All of these controllers are used mainly
in industrial sectors (chemicals, petrochemicals, steel, food
processing, energy production, etc…) of transportation (automotive,
aeronautics), but also in the residential sector and tertiary (heating, air
conditioning, etc...) The choice of a heat exchanger, for a given
application depends on many parameters: field temperature and
pressure of fluids, and physical properties of aggressive fluids,
maintenance and space. It is clear that the fact of having an
exchanger appropriate, well-sized, well made and well used allows
gain efficiency and energy processes.
