Dear Students/Parents
We at 'Apex Institute' are committed to provide our students best quality education with ethics. Moving in this direction, we have decided that unlike other expensive and 5star facility type institutes who are huge investors and advertisers, we shall not invest huge amount of money in advertisements. It shall rather be invested on the betterment, enhancement of quality and resources at our center.
We are just looking forward to have 'word-of-mouth' publicity instead. Because, there is only a satisfied student and his/her parents can judge an institute's quality and it's faculty members coaching.
Those coaching institutes, who are investing highly on advertisements, are actually, wasting their money on it, in a sense. Rather, the money should be invested on highly experienced faculty members and on teaching gears.
We all at 'Apex' are taking this initiative to improve the quality of education along-with each student's development and growth.
Committed to excellence...
With best wishes.

APEX INSTITUTE was conceptualized in May 2008, keeping in view the dreams of young students by the vision & toil of Er. Shahid Iqbal. We had a very humble beginning as an institute for IIT-JEE / Medical, with a vision to provide an ideal launch pad for serious JEE students . We actually started to make a difference in the way students think and approach problems. We started to develop ways to enhance students IQ. We started to leave an indelible mark on the students who have undergone APEX training. That is why APEX INSTITUTE is very well known of its quality of education and the dedication towards its target.

With the continuation of our previous research here, we report important structural information, geometry, and thermal stability of the synthesized compounds. The trend of the recorded data gives precise information about the crystallinity of the metal complexes.
How Carbon Nanotubes Collapse on Different Ag Surface?ijrap
The collapse and stability of carbon nanotubes (CNTs) on noble metal silver different surfaces were studied
using molecular mechanics and molecular dynamics simulations. From the results, it can be seen that the
CNTs can collapse spontaneously onto different silver surface [(1 0 0), (1 1 0), (1 1 1)] due to the van der
Waals force between them. Furthermore, the CNT collapsing on (1 0 0) and (1 1 1) surface are much easier
than that on (1 1 0) surface. Moreover, the results show that the collapsed CNTs exhibit as linked graphene
ribbons and have the largest area to contact with the Ag surface, which greatly enhances adhesion between
the CNTs and the Ag surface and keeps the system much more stable.

Interparticle Interactions and Dynamics in Solutions of Copper (II), Cobalt (...Dmitry Novikov
This presentation is a report from the PLMMP-2018 conference. For any information contact me here: dmitrynovikovs@gmail.com
Abstract
This work is a continuation of the systematic study of unsymmetrical electrolytes in non-aqueous media, carried out at the Department of Inorganic Chemistry of V.N. Karazin Kharkiv National University [1].
Here we report the results of the conductometric study of diluted solutions of Cu(BF4)2, Zn(BF4)2 and Co(BF4)2 in acetonitrile (AN) at 5-55 oC. The extended Lee-Wheaton equation was used to procced conductometric data and obtain primary association constants, limiting equivalent conductance of electrolytes and limiting ionic conductivities. The primary association constants were then used to interpret the contribution of the ionic solvation and association in terms of contact ionic pairs, solvent-separated ionic pairs and short-range non-Coulomb interionic potential.
Obtained values of total limiting equivalent conductivity of electrolyte and the limiting conventional transference numbers allowed us to divide the equivalent conductivity on ionic constituents. These data were later proceeded to evaluate the parameter of dynamics of ionic solvation, within the modified theory of the dielectric friction.
Additionally, densimetric study was carried out to derive structural parameters of ion solvation of Cu(BF4)2, Zn(BF4)2 and Co(BF4)2 in AN at 5-55 oC.
Finally, molecular dynamics simulations were performed on the same electrolyte/AN systems by means of MDNAES package [2] to elucidate particle dynamics and microscopic structure within the first and second co-ordination shells of copper (II), cobalt (II) and zinc (II) cations in AN at 25 °C.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms. He is known for his dynamic presentations in CI/CD and application security integrated in software delivery lifecycle.

PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.
Let's dive deeper into the world of ODC! Ricardo Alves (OutSystems) will join us to tell all about the new Data Fabric. After that, Sezen de Bruijn (OutSystems) will get into the details on how to best design a sturdy architecture within ODC.

5. Answer Exercise 1: Lattice defects
Stacking fault:
Instead of ABCABCABC => stacking order ABCABAABC
Stacking faults develop during crystal growth or because of
interaction with dislocations.
Twin boundary:
Twin boundaries are characterized by a symmetric arrangement of the
atoms with reference to a vertical plane.
6. Particle (precipitation, dispersion):
Field of lattice with changed structure.
Precipitations are formed in the material because of
thermodynamic equilibrium (formation of a new phase via heat
treatment of a meta-stable solid solution).
Dispersions are extra phase of small particles distributed in
the material.
Edge dislocation:
An edge dislocation is characterized by an
additional half-lattice plane.
It is caused by vacancy diffusion.
7. Exercise 2: Vacancies
i) State the correlation between the concentration of vacancies cv and temperature. By the aid of
a diagram (plot), describe this relationship qualitatively.
ii) State the order of magnitude of cv in metallic materials at their melting temperature.

17. Exercise 4: Different alloy materials
i)The diagrams in Figure 2a and b depict alloys of different kinds. Ascribe to each of the
diagrams their proper designations.
ii) What are the main differences between these two kinds of alloys?
Figure 2. (a) (b)
18. Figure 2. (a) (b)
Answer Exercise 4: Different alloy materials
i)Figure 2a represents the structure of a heterogeneous alloy while Figure 2b represents the
structure of a homogeneous alloy.
ii) Heterogeneous alloys have grains which are chemically and structurally different.
Homogeneous alloys are solid solutions in which the atoms of combining species are in structura
unity (i.e. atoms of the solute are completely miscible in the lattice of the solvent.
19. Exercise 5: The phase rule
i)Write the expression of the phase rule and define the variables in this expression.
ii)Explain the significance of the reduced phase rule
20. Answer Exercise 5: The phase rule
i)Write the expression of the phase rule and define the variables in this expression.
The phase rule is given by: F + P = C + 2
This phase rule is helpful for the physical characterisation of a “thermodynamic” system.
Where C is the number of components in P number of phases having F degrees of freedom.
- The components are the chemical elements of the system. Note that compounds with fixed
chemical composition are treated as one chemical element in the phase rule.
-The phases are areas of materials which are physically and chemically different from each othe
and are separated by interfaces (phase interfaces or boundaries)
-The degree of freedom represents the state variables of a system which can be changed
independently without changing the number of phases. Established state variables are: Pressure
Temperature and the concentration of the chemical species or components present in the system
ii) Explain the significance of the reduced phase rule.
The reduced phase rule provide a reasonable basis for describing real equilibrium system, as is
commonly encountered in technical practice. Since most investigations in materials science are
carried out at standard pressure i.e. p = const. = 1 atm = 1.013 bar.
Since in this case the degree of freedom of pressure is already occupied, thus the result degree
of freedom would be: F* = F - 1. Hence the „reduced phase rule“ is: (F* + 1) + P = C + 2
or F* + P = C + 1
21. Exercise 6: Change of state in materials
i)Describe, using an appropriate diagram, the transformation of materials from the liquid solid
gaseous state. (consider the roles of temperature and enthalpy in your answer)
Figure 3. Relationship between temperature T and enthalpy H for a metal without phase transition in the
solid state
22. Figure 3. Relationship between temperature T and enthalpy H for a metal without phase transition in the
solid state
Answer Exercise 6: Change of state in materials
i)Figure 3 illustrate the transformation of a materials from the solid to the liquid state.
23. Exercise 7: Construction of phase diagrams
i)Consider the temperature / time relation associated with a two component system AB where
component A has a melting temperature (TM,A) relatively higher than that of B (TM,B). The profile in
Figure 4 shows the influence of concentration of both components on the T – t diagram.
For a system where the concentration of both components are varied accordingly, you are required
to use the thermal analysis information in Figure 5 (next slide) to construct a binary phase diagram
Figure 4. Temperature – time plot for a two component system (p is constant)
24. Exercise 7: Construction of phase diagrams
i)You are required to use the thermal analysis information below to construct a binary phase
diagram.
Figure 5. Temperature – time profile for a
two component system.
25. Answer Exercise 7: Construction of phase diagrams
Determining phase diagrams
procedure:
1. Registration of the T, t-curves for sufficient amount of cB with adequately
slow „cooling in equilibrium“
2. Transition of hold points and so called knee points in the T, cB-diagram
(→ phase diagram)
3.Connection of all liquidus and solidus points including melting points of the pure
components A and B by a single line each
------------------------------------------------------------------------------------------------
Liquidus line and solidus line:
• are lines of equilibrium!
• they mark the boundaries of phase fields
⇒ area of melting temperature “M“
(1 phase)
⇒ area of melting temperature and
solid solution “M” + “α” (2 phases)
⇒ area of solid solution “α” (1 phase)
