Lenalidomide inhibits the proliferation of chronic lymphocytic leukemia (CLL) cells through a mechanism dependent on cereblon and p21, but independent of p53. Treatment with lenalidomide upregulates the expression of the cyclin-dependent kinase inhibitor p21 in CLL cells, leading to inhibition of proliferation. Silencing of either cereblon or p21 impairs the ability of lenalidomide to inhibit CLL cell proliferation. Lenalidomide also induces p21 expression in CLL cells isolated from patients, indicating it can directly inhibit CLL cell proliferation through cereblon and p21 in vivo.

Advanced control scheme of doubly fed induction generator for wind turbine us...IJECEIAES
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

Comparative analysis between traditional aquaponics and reconstructed aquapon...bijceesjournal
The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.
Electric vehicle and photovoltaic advanced roles in enhancing the financial p...IJECEIAES
Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network

6. EQUIPMENTS
USED:
1.TRANSIT MIXER
It is device that homogeneously combines cement, aggregate such as sand
or gravel, and water to form concrete.
Transit mixer is truck mounted by a revolving drum to mix the components.
For smaller volume works portable concrete mixers are often used so that
the concrete can be made at the construction site.
7. 2.CONCRETE PUMP
The main type of concrete pump is either mounted on a truck and known as a
truck-mounted concrete pump or placed on a trailer, and it is commonly
referred to as a line pump or trailer-mounted concrete pump.
This pump requires steel or rubber concrete placing hoses to be manually
attached to the outlet of the machine.
10. PROCEDURE
1.EXCAVATION
Excavation was carried out both manually as well as mechanically.
Adequate precautions are taken to see that the excavation operations do
not affect the adjoining structures.
USE OF P.C.C
After the process of excavation, laying of plain cement concrete that is PCC
is done. A layer of 75 mm was made in such a manner that it was not
mixed with the soil.
It provides a solid base for the raft foundation and a mix of 1:3:6 that is, 1
part of cement to 3 parts of fine aggregates and 6 parts of coarse
aggregates by volume were used in it
2.LAYING OF FOUNDATION
At the site, Raft foundations was used to spread the load from a structure
over a large area, normally the entire area of the structure.Normally raft
foundation is used when large load is to be distributed and it is not possible
to provide individual footings.Raft foundations have the advantage of
reducing differential settlements as the concrete slab resists differential
movements between loading positions.
11. CONDITIONS TO USE RAFT FOUNDATION:
They are often needed on soft or loose soils with low bearing capacity.
Raft Foundation had a thickness of 750 mm. Bars of 25mm to 16mm were
used.
3.FORMWORK :Forms or moulds or shutters are the receptacles in
which concrete is placed, so that it will have the desired shape or outline
when hardened. Once the concrete develops adequate strength, the forms
are removed. Forms are generally made of the materials like timber etc.
12. 4.CONCRETING
Type of Cement Used :P.P.C (A.C.C)
Grade of concrete in slabs and beams :M-20
Grade of concrete in coloumns:M-30
Grade of concrete in P.C.C work:M-10

were provided respectively in the corner and in the
middle.
4.From 9 th onwards till the end the bars of dia. 16
mm and 12 mm were provided.
15. 7.RING/TIE BARS
8 mm dia. bars were used as ring.
The larger ring was of dimension 650*150 mm which
holds the corner bars and the smaller ring was of
dimension 350*150 which holds the inner bars.
Spacing between the rings:
The spacing between the top and the next ring was
80 mm and also the same spacing was provided for
the bottommost and the ring above it.
Rest all the spacing between the rings was 120mm.
16. 8. Beams:
1.Beams were of sizes 230*400,small beams of size
230*160 was also provided.
2.Main Reinforcement: Mostly bars of dia 25,20 and
16 mm were provided.

2.Stirrups were provided for the shear reinforcement
,1st stirrup is at 40 mm from face of the supporting
member.
3.Spacing of the stirrup was upto 2*(dia of the main
bar)
17. 9.Slab:
1.Main bars used were of 12 mm at the top and also
at the bottom.
2.Chairs were provided at different locations to
provide the spacing required between the top and
bottom reinforcement.
3.Thickness of the slab was 100 mm.
18. 10. Cover block:
1.Cover blocks are placed to prevent the steel rods
from touching the shuttering plates and there by
providing a minimum cover and fix the
reinforcements as per the design drawings.
2.Covers should be made of cement sand mortar (1:3).
Ideally, cover should have strength similar to the
surrounding concrete, with the least perimeter so
that chances of water to penetrate through
periphery will be minimized.
19. CONCLUSION
This Field Work is comprehensive in filling the gap
between the theoretical & practical studies
At the site there was a good management system
between the contractor, the consultant, and the
client.
I found that there was good understanding between
the supervisor and the workers, though works
areinterdependent but there were no contradiction
between them.
