Privacy preserving data mining is a latest research area in the eld of data
mining. It is dened as “protecting user’s information”. Protection of privacy has
become important in data mining research because of the increasing ability to store
personal data about users and the development of data mining algorithms to infer this
information. e main goal in privacy preserving data mining is to develop a system
for modifying the original data in some way, so that the private data and knowledge
remain private even aer the mining process. In this paper we propos a system that
used PAM (partitioning around medoid) clustering algorithm in health datasets in
order to generate set of clusters, then we suggest protecting the sensitive attributes
in each cluster in order to increasing the privacy of users information. Protecting
the sensitive attributes is done by using privacy techniques through modifying the
data values (attributes) in the dataset. We suggest using randomization technique Data copying (which is a new suggested technique in this paper) to prevent attacker
from concluding users privacy information. Aer modication, the same clustering
algorithm is applied to modied data set to verify whether the sensitive attributes
are hidden or not. Experimental results on these proposed techniques prove that the
PAM algorithm is ecient for clustering in all data sets and the selected clusters are
protected eciently by using Data Copying technique. is technique is applied to
Wisconsin breast cancer and diabetes data set. Finally the results of the proposed
system prove that the distortion of data can be reduced when the privacy ratio was
increased. ese are important issues in PPDM, therefore the proposed system is
highly successful in achieving the protection of privacy

In this work, the effect of four types of inorganic phosphorus salts on flammability for polyester
and epoxy resins has been studied in the weight ratios of (0.5, 1.5, 2.5 & 3.5%) by preparing films
of (130×130×3) mm3
in diameter, Three standard tests method were used to measure the flame
retardation which are; ASTM: D-2863, ASTM: D-635 & ASTM: D-3014.
The results obtained from these tests indicated that additive IV has high efficiency as a flame
retardant, self-extinguishing (S.E), occurred at the percentage 0.5% for unsaturated polyester resin
and the percentage 1.5% for epoxy resin. Non-burning (N.B), occurred at the percentage 2.5% for
unsaturated polyester resin and at the percentage 3.5% for epoxy resin. Additives I and II show low
effect on retard combustion in both resins

Ligand N2
donor (N,N’-bis (3,4,5-trimethoxybenzalidene) dithiooxamide (LH)) has been prepared
from dithiooxamide with 3,4,5-trimethoxybenzaldehyde. The reaction was reflexed for 12 h. at 70
ºC. Co (II), Ni (II), Cu(II), Pd (II) and Pt (IV) complexes were synthesized via reaction between
appropriate metal ion and the ligand (LH). The ligand (LH) characterized by CHNS elemental
analysis, Infrared spectroscopy (FT-IR), H-NMR-spectroscopy and UV-Visible spectroscopy. The
complexes characterized by Infrared spectroscopy (FT-IR), 1HNMR-spectroscopy, UV-Visible
spectroscopy,magnetic susceptibility and conductivity measurements. From the analytical and
spectral data, the stoichiometry has been found to be 1:2 for all the complexes. The Spectral data
confirms well coordination of Schiff-bases ligand with the metal through imine nitrogen atoms of
Schiff base moiety. Conductivity of complexes were measured using DMSO as a solvent where
conductivities of complexes were ionic in ratio (1:2)..The ligand LH, Ni (LH)2
and Cu (LH)2
showed
greater activity against Aspergillus niger. while the complexes Co (LH)2
, Pd (LH)2
and Pt (LH)2
not
show any activity against this fungi

We study some chaotic properties on G-space, we prove if f is G-localy eventually onto then f
is G-sensitive dependence on initial conditions, also if f is G-chain sensitive then is also G-chain
sensitive when f ≈ h.Also we generalize some properties about G-blending

Background: Method optimization of drug analysis is an arising approach among multidisciplinary
science fields. The High performance liquid chromatography (HPLC) has been approved to be the
cornerstone of drug analysis. Over the last ten years, HPLC has been figured as the analysis method
of choice for many compounds. HPLC system has been utilized in diversified applications such
as: the quantitative/qualitative analyses of biological samples, calculating the amounts of active
pharmaceutical ingredient (API), isolating specific components from their mixtures, and many others. This work aims to qualify and quantify the caffeine in two different pharmaceutical formulas
namely; Panadol® Extra tablets and Thicker Fuller Hair® shampoo employing RP-HPLC.
Methods: Isocratic method was utilized with fixed mobile phase ratio as methanol: water (40:60).
The flow rate was 0.8 ml/min while the wavelength was 273nm. Calibration curve was plotted via
the utilization of the following concentrations (0.0, 20, 40, 60, and 80) µg/ml. Thirty six caffeinated
tablet samples were examined as dissolved by methanol and filtered with 0.22 µm nylon-membrane
syringe filter and diluted. On the other hand three independent caffeinated shampoo samples were
examined. The samples were diluted, shacked, and filtered with 0.22 µm nylon-membrane syringe
filters. Finally, the diluted solutions were injected to the RP-HPLC and the data was observed and
recorded.
Results: The areas required to plot the calibration curve were observed. The caffeine peak
was identified within each pharmaceutical sample. Consequently the identified peaks were also
quantified. The mean content of caffeine in caffeinated tablets was found to be 64.96 mg. Moreover,
the caffeine concentration in the shampoo was observed as 0.0047%.
Discussion and conclusion: In this work the RP-HPLC has been utilized in the qualification and
quantification of caffeine in two different pharmaceutical formulas namely; Panadol® Extra tablets
and Thicker Fuller Hair® shampoo. HPLC technology has matured to the extent that almost any
existing drug can be analyzed by an existing method that can be found in the analytical literatures.
For future work other drugs can be examined or even multidrug formulas can be tried with such
accurate and precise RP-HPLC technique

License plate recognition has been entered in many critical systems like tracking stolen cars,
traffic surveillance and parking management. License plate recognition process consists of three
parts; the first part is identifying the position of the license plate, second, segments license plate into
individual image characters and the third is recognizing these characters. License plate is influenced
by the noise in the real world such as illumination and angle of the camera, so that the accuracy of
locating, segmenting and recognizing are affected. There are many methods for each part, choosing
any method of them depends on the type of application and its environment as well as the execution
time. In this paper, we will survey and study the methods used in recognition part

The effect of mid layer on flexural strength and young modulus were studied using Instron testing
machine. E-glass/epoxy composites were manufactured using hand lay-up technique. The laminated
composites were prepared with dimension (4x10x80) mm, Epoxy composites were reinforced with
multidirectional layer of woven glass fiber and random glass fiber of stacking sequence [M]16,
[R]16, [M/R//M1/M1//R/M]s, [//M/R//]s, and [R/M//R1/R1//M/R]s. The effect of transverse loading
on flexural strength and young modulus was investigated for specimens subjected to Three-point
bending test.
The results show that the mid layer (M1/M1) which had (homogeneous distribution) has higher
flexural strength value and young modulus than mid layer (M1/R1) and (R1/R1).
