Abstract:
At present, the calculation of
2nd/3rd/4th degree equations in one variable is complicated, and
it is difficult to universally apply. There is no solution for
entangled one-variable 5th degree calculus equations. Propose a
circle logarithm algorithm: One of the highlights is the
integration of discrete data statistics and entangled neural
network analysis, and arithmetic analysis is performed between
unlabeled circle logarithms {0 to 1}. It involves the foundation
of mathematics, the reform of traditional calculus, and the
algorithm of a new generation of computer neural networks. Here
is a reorganization of the bylaws to solve the complete problem
of the 2nd/3rd/4th/5th degree calculus equation, and provide
relevant experts, scholars, readers to verify and check the
calculation, and it can also be converted into the compilation
of new computer programs.

Abstract :There
has been a renewed interest in developing more flexible
statistical distributions in recent decades. A major milestone
in the methods for generating statistical distributions is
undoubtedly the system of differential equation approach. There
is a recent renewed interest in generating skewed distributions.
In this research, a new
four parameter lifetime distribution which extends the Lomax
distribution is introduced by compounding the Lomax distribution
with the complementary generalized transmuted Poisson family of
distributions. The probability density function and cumulative
distribution function as well as some basic statistical
properties of the new distribution, such as moments, reliability
function, hazard function, quantile function, residual life
function, entropy and the order statistics were derived. Some
plots of the distribution shows that it is a positively skewed
distribution. The maximum likelihood estimation method is used
to estimate the parameters of the new distribution. A simulation
study to assess the performance of the parameters of the newly
developed distribution was provided with an application to real
life data to assess its potentiality. The result shows that the
proposed distribution provides better fit than some
generalizations of the Lomax.

Abstract:
A tsunami or tidal wave, also
known as a seismic sea wave, is a series of waves in water body
caused by the displacement of aa large volume of water,
generally in an ocean or a large lake. Some studies have been
conducted by me on the tsunamis to invent a device that should
be used to study and predict the tsunamies and designed an
architecture named Geoscope in 1987 to keeping the tsunamis.
Geoscope is not what Buckminster had proposed in 1962.
Let us study
about the exploitation of
tsunamis
and the
methods of studying
tsunamis.

Abstract :Background:
The metabolic syndrome (Met
S) is a cluster of the most dangerous heart attack risk factors
as diabetes, abdominal obesity, high cholesterol, and high blood
pressure. Protein tyrosine
phosphatase 1B (PTP1B), is negatively regulating the leptin and
insulin signaling, with positive correlation with adiposity and
contributes to insulin resistance. The effect of PTP1B on the
obesity is still vague. This study aimed to study the
effect of PTPN1 genetic
variations (467T>C) on
susceptibility to Met S components and its metabolic traits by
comparing the PTPN1
gene (467T>C)
alleles and genotypes between T2D patients with Met S and
healthy Egyptian subjects. Methods: Polymerase
chain reaction/restriction fragment length polymorphism (PCR-RFLP)
analyses were carried out to detect the 467T>C variants of
PTPN1 gene in 100 Egyptian patients with obesity as compared
to controls (n=80).
Results:
The results did not detect any
significant difference in 467T>C
PTPN1 genotypes
between patients and control groups (X2=
0.674, P= 0.714). 467T>C
PTPN1
variants showed non-significant
association with Met S components [diabetic metabolic traits in
both groups ; plasma insulin levels, fasting blood glucose
levels (FBG) , HOMA-IR , abdominal obesity [Waist circumference
(WC) , body mass index (BMI)], the lipid profile parameters ,
diastolic blood pressure (DBP) and systolic blood pressure (SBP).
Conclusion:
The PTPN1 promoter variant of 467T>C was not associated
with Met S components and T2D metabolic related traits in Type 2
diabetic Egyptian patients. More studies are required on a
larger scale to examine any potential metabolic association.

Abstract
:Concrete is known to be the most used construction
material worldwide. The environmental and economic aspects of
Ordinary Portland Cement (OPC) containing concrete, have led
research studies to investigate the possibility of incorporating
Supplementary Cementitious Materials (SCMs) in concrete.
Metakaolin (MK) is one SCM with high pozzolanic reactivity
generated throughout the thermal activation of high purity
kaolinite clay at a temperature ranging from 500° C to 800° C.
Although many studies have evaluated the effect of MK on
mechanical properties of concrete and have reported positive
effects, limited articles are considering the effect of MK on
durability properties of concrete. Considering the lifetime
assessment of concrete structures, the durability of concrete
has become of particular interest recently. In the present work,
the influences of MK on mechanical and durability properties of
concrete mixtures are evaluated. Various experiments such as
slump flow test, compressive strength, water permeability,
freeze and thaw cycles, rapid chloride penetration and surface
resistivity tests were carried out to
determine mechanical and durability properties of concretes.
Concretes made with the incorporation of MK revealed better
mechanical and durability properties compared to control
concretes due to combined pozzolanic reactivity and filler
effect of MK.

Abstract:
QLED TV is a new television technology that is taking many of
its cues from OLED TV technology. It consists of extremely small
light-emitting crystals called quantum dots. Most TVs today
including all of those made by companies and just about every
other TV brand are based on decades-old LCD, or liquid crystal
display, technology. In the past few years’ Better technology
and more advanced manufactured, called OLED or organic
light-emitting diode. OLED TVs have the best picture quality
we've ever tested, keeping LCD-only companies from achieving the
coveted top positions on certain lists. At the moment a new TV
display technology on the horizon called QLED, and it might be
even better than OLED and LED. Short for "quantum dot light
emitting devices," QLED has the potential to match the infinite
contrast ratio of OLED, with better power efficiency, better
color and more .
In this article we will discuss
about the QLED and OLED display technology.

Abstract:
Study of earthquakes in
geological hazards is a key element. Many researches &studies
have been conducted by me on the earthquakes to invent a device
that should be used to study and predict the earthquakes and
also solve the mysteries and other problems of the earth’s
underground and designed an architecture named Geoscope in 1987
to keeping the entire earth’s underground to be under control of
the geoscope with many revolutionary proposals. This is not what
Buckminster had proposed in 1962. My Geoscope was designed to
study the earth’s underground mysteries, explore the underground
minerals and predict the geological hazards and consisting of
revolutionary proposals just like attracting the sea waters to
the underground areas of deserts through the layers by
electro-ionization and attracting the vaporized sea waters to
the desert plains through the sky by geo-magnetizing atmosphere
when the weather is surrounded by water molecules during the
trough of low pressure areas by constantly studying the
underground.
Let us, study
about the exploitation of earthquakes and the methods of
studying earthquakes. Seismic luminescence is one of the key
study in earthquakes forecasting methods.

Abstract:
Barley is susceptible to salinity but shows genotypic variation
for salt tolerance. The hydroponic assessment of different
barely genotypes for salt tolerance solution culture-based study
was conducted to observe the behavior of varieties of Hordeum
Vulgare L. against various salt concentrations. For this
purpose, nine varieties were evaluated for 42 days at various
salt levels (0mM, 100mM and 200mM). In this study the
data on followed parameters like, root length, root fresh
weight, root dry weight and chlorophyll contents were recorded.
The study was organized and analyzed by CRD technique having 3
replications. By using standard procedures, the collected
information of study was statistically organized. Among nine
genotypes A02, A03 and A07 were declared salt tolerant on the
basis of studied characters.

Abstract:
Background:
Survivin is one of the inhibitors of apoptosis proteins family (IAP)
and its expression in keloid was significantly higher than in
normal skin tissue. Tacrolimus (FK506) is a calcineurin
phosphatase inhibitor inhibits synthesis of inflammatory
cytokines produced by T- lymphocytes and induces apoptosis
through caspase-3 activation. Intralesional steroid (IL) is a
corner stone in keloid treatment.
Objectives:
To assess survivin level as
antiapoptotic factor in keloid and to evaluate the therapeutic
effect of topical tacrolimus compared to IL steroid clinically
and immunohistochemically.
Patient
and Methods:
fourty keloid patients were included in this study, twenty were
treated by intralesional steroid and twenty were treated by
topical tacrolimus for three months. Survivin level was
estimated in keloid tissue before and after treatment.
Results:
Our study showed statistically significant higher level in the
dermal and epidermal survivin immunoexpression (p-value <0.05)
in the keloid tissue as compared to the normal skin tissue.
There was a statistically significant decrease (p-value <0.05)
in the dermal and epidermal survivin immunoexprssion as well as
Vancouvre Scar Scale (VSS) after treatment in both steroid and
tacrolimus groups without significant difference between both
modalities. Keloid improvement was higher in steroid group (45%)
than in tacrolimus group (25%); however, there was no
statistically significant difference in keloid improvement
between both treatment groups.
Conclusion:
Survivin plays a role in pathogenesis
of keloid. Topical tacrolimus showed therapeutic effect
in keloid treatment,
however ILsteroid is the corner stone treatment modality of
keloid.
