The problem of minimizing a function of three criteria maximum lateness, maximum
earliness and sum of completion time in hierarchical method is discussed in this paper.
A set of n independent jobs has to be scheduled on a single machine that is continuously
available from time zero onwards and that can handle no more than one job at a time. Job j
(j=1,2,…,n) requires processing during a given positive uninterrupted time pj.
Some algorithms to find exact and best possible solutions are proposed for the problem of
three criteria maximum lateness, maximum earliness and sum of completion time in
hierarchical case.

More and more data is available on database every day. The greater the amount of data in database led
to create a problem in process and retrieving the required data. Security is one of the significant
challenges that people are faced over the entire world in every aspect of their lives. Databases are
vulnerable to attack from internal and external threats. One of security dialogues is data
encryption/decryption whenever data being transmitted over communication lines may be protected by
encrypting the data, which can be decrypted only by the authorized person. The retrieval from big
encrypted database stills a big problem. The proposed system presents a new method used to retrieve
data from (encrypted database; encrypted compressed database or encrypted dynamic clusters). These
data retrieved represents the answers to the user query. In this research the retrieving from big
encrypted database was processed by matching cipher query with encrypted database. The proposed
system uses clustering technique to build block of data according to the encrypted user query (entries
or requirements). The comparison includes the retrieving time that was required from matching plain
query with plain data and cipher query with cipher data. In traditional system the retrieving was done
by decrypting the entire database or decrypting part of it to find the data that matched the user query.
This would be consumed too large time. The work of this paper allows to the users to query over
encrypted database without decrypting the database, instead of that, it work on comparing cipher query
with encrypted database and retrieving the results in cipher form. The data retrieval process is
considered the main objective of this research and not the encryption process. So, the simple
encryption operation was used to measure the performance of the data retrieving method (by matching
encrypted query with encrypted data).

The present study was carried out to find out the antimicrobial activity of endophytic bacteria
isolated from wheat plant root by surface sterilization method. Bacterial strain was identified

between (16.5-31.0)mm and range between(29.5-33.0)mm against Gram-Positive Bacteria and
antifungal activates tested against yeasts test namely; Candida albicans with inhibition zone
16.0mm and 12.0mm against Candida kruzi. Minimum inhibitory concentrations were in the
range between (6.25- 12.25) and (3.12-25.0) μg/ ml against Gram-Negative and Gram-Positive
bacteria respectively and(50)μg/ml against yeasts test and minimal bactericidal concentrations
ranged from (12.5 to 25.0) μg/ ml and (6.12-50)μg/ ml against Gram-Negative and Gram-
Positive bacteria respectively and minimal fungicidal concentrations (100) μg/ ml against
yeasts. The antioxidant activity was analyzed using2,2-diphenyl-1-picrylhydrazyl (DPPH)
scavenging assays have shown high rates of inhibition .A verification of non toxicity of the
bacterial secondary metabolites against human blood revealed a negative test. The metabolite
produced by the endophytic bacteria could be an alternative source of antimicrobial and
antioxidants.

Various types of contraceptives were developed. These contraceptives are prepared from
natural as well as synthetic sources. The study was conducted on 15 mature adult females, and
males of rabbits.10 from each female and male rabbits were treated with Melia azedarach in
powder form at a dose rate of 6 g / kg b.wt. orally mixed with feed daily for 53days, the
remaining 5 from each of female and male rabbits remain non treated. In 28th day post exposure
to Melia; the animals were divided into 3 groups. Group I represented females non treated with
plant crossed with treated males. Group II represented treated females crossed with non treated
males. Group III represented non treated females crossed with non treated males. The mixing
continued for 10 days. All females were examined for pregnancy by sonar weekly. At 56th day
post treatment with plant 3 females from each group were killed, while others 2 female rabbits
were left till birth. Size, weight and characters of naturally birthed fetuses and those found
during explore the uterine horns of killed rabbits were fixed. Other dependent parameters in
this study were hematological and some of constituents of serum. The results of the study
revealed a non significant decrease in body weight, body temperature, heart rates, respiratory
rate, clotting time and bleeding time. Erythrocytes counts, PCV, MCV values were not
significantly increased in treated group, while in non treated group these were not significantly
decreased. Hb, MCH, MCHC were not significantly changed in both groups. Total leucocytes
count in treated group were decreased, whilst increased in non treated group. Heterophils%
were decreased in treated group. Lymphocytes percentage in treated group were increased, on ther hand monocytes, eosinophil and basophils percentages did not show any significant
changes. The results revealed that infertility index was 0, 20 and 100% in group I, II and III

Pattern recognition is a process of identifying vector of correlated/uncorrelated attributes and
discriminate it among other patterns. Pattern recognition is synonymous to machine learning,
data mining and Knowledge Discovery in Database (KDD).In this research work we investigate
decomposing pattern (i.e., attribute vector) space into subspaces in which patterns cluster
around basis of the subspaces. This paper introduces a theory which states that in case of having
space of vectors and having basis then Signal Value Decomposition (SVD) can perform
excellent in discovering thesis basis, hence, in pattern recognition a space can be decomposed
to sub-spaces to reach clustering around basis. Results are collected and discussed and it has
proven that SVD and its extension Latent Segment Analysis (LSA) can optimize the process of
machine learning and showed a great tendency to converge toward cognitive based recognition.

samples were taken from the spaces between the plants. pH, electrical conductivity (EC), and
organic matter (OM) were measured. The results showed that pH under L. shawii and C.
dactylon gave closed value and had significant difference with the rest of species. The electrical
conductivity was found to be closed value C. spinosa and S. bicolor with each other and the values of low in significant difference with the rest of the target species. Control treatments is
significantly different from other in organic matter.

In this days many data exchanged over the Internet, so finding the best solution that offer the
necessary protection against the information hackers becomes the basic goals of many
researches. Many researches focus on the Encryption algorithms that play a main role in
information security systems. The goal of every encryption algorithm is to make it as hard as
possible. If a good encryption algorithm is used, there is no technique considerably better than
trying every possible key to break the cipher text. It is difficult to define the quality of an
encryption algorithm. Sometimes algorithms look strong and complicated but turn out to be
very easy to break.In this research, a new encryption method is proposed to encrypt Arabic text
by using the standard of first order equation for three variables. The sender and the recipient
will share a first order equation for three variables and two randomly constants represent the
values of y, z which represent the keys of used in encryption\decryption process. The result of
the equation xored with randomly shared value between both sides which is represent the third
key for the proposed method to get final cipher text of the proposed method. By applying
different cryptanalysis techniques such as berlekamp Massey cryptanalysis, linear feedback
shift register (LFSR), autocorrelation attack, brute force attack , frequency attack, m-138 cipher
text only attack and side – channel attack to test the inevitability of the proposed method, the
results showed that the proposed method is hard to be broken by the crypt analytics and
attackers. Moreover, comparing the timing and performance of the proposed method with the block and stream ciphers showed the proposed method is better than the block and stream
ciphers in these measures.

aureus, E. coli, Pseudomonas aerugenosa and Proteus mirabilis). To conclude, the
antimicrobial activity of the aqueous and methanolic extracts of Citrus aurantium L. leaves
was efficiency against some bacteria strains.

The associations amongst cholesterol levels and ABO blood groups has been established but
differ in many studies. Hypercholesteremia remained powerfully associated in the progress of
cardiovascular diseases. The present study was carried out to estimated cholesterol
concentration and blood group in the sera samples of (100) Iraqi people at the age range (20
70) years. Serum cholesterol done by auto-analyzer, while blood group by direct agglutination
technique. The aim of this study to recognized whether the cholesterol level was related to ABO
blood group in coronary heart disease individual. The study clarified increased concentration
of cholesterol at the age (50-59 and 60-70) years other than age groups and observed that
increased percentage of concentration of cholesterol in female (60%) more than male
(40%).Also appeared that concentration of cholesterol increased at the blood group A+(33%) ,
B+(28%) , O+(12%) and AB+(11%) compared with other blood groups. So we concluded that
cholesterol level was elevated in blood group A+ and B+ more than other blood group.

Opioids are perhaps the most efficacious analgesic agents influencing a large number of body
functions. The objective of this study is to observe changes in hemodynamic, electrolytes, and
kidney and thyroid functions of opium treatment in rats. Thirty male rats were randomly
distributed into three groups. Group 1 regarded as control, while in group 2 and 3, the animals
were daily injected intraperitoneally with opium for seven successive days. Intraperitoneal
opium injection caused a dose-deponent increase in serum calcium (Ca+2 )and phosphate (PO4
) levels, whereas the nitric oxide (NO), triiodothyronine (T3) and thyroxine (T4) levels were
significantly decreased in both doses. The significant decrease in serum (NO )level and increase
serum (Ca2+) and (PO4-) levels resulted in significant elevation of systolic blood pressure (SBP)
accompanied by elevation of serum bilirubin and urea. Our finding suggests that opium causes
hypertension, kidney and thyroid function abnormalities mostly in concentration dependent
manner.

DNA computing has prevailed in the field of cryptography. DNA cryptography uses DNA as
an information transporter and gets benefit from biotechnology in order to achieve encryption.
Encryption character algorithm proposed by Kang et al relying on pseudo-DNA operation,
However, DNA encryption methods have defects such as expensive experimental equipment,
complex operation and difficult to understand its biotechnology and remains cannot be
effectively applied in encryption field. Also the chaos theories can generator dynamic system
with random numbers. In this paper; a design new approach for encryption image was suggested
depending on proposal DNA computing such as (coding, decoding) with multi-operation in
festiel structure to increase more complexity when an attacker tries image retrieval. When used
NLFSR as random generate system to mixing to increase complexity also was proposed new
idea to generated secret key. A performance analysis in measurement test between the original
image and encryption image was evaluated, the values rustle is big to depend on no correlation
for a pixel in original and cipher image. Another test between plain image and clear image after
decryption are good values for a statistical test. MSE is equal to zero and PSNR infinity number
because no loss data or difference in this approach was found.

methods of Ag ions in aqueous solutions in the presence of strong reducing agents like hydrogen
peroxide (NaBH4) with different concentrations of silver nitrate AgNO3 (1mM to 0.9mM)
improving its effect on the stability of the nanoparticles. From the results, stability of the Ag
nanoparticles is due to the ions of NaBH4 that surrounding the nanoparticles and decreased from
aggregating as demonstrated by using UV-VIS spectra, Particle size analyzer (PSA) , Scanning
Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM) to determine their
behavior as catalyst materials and analysis the kinetics of reactions

Video became something important of our daily lives and in many areas such as surveillance
cameras and mobile cameras therefore it has attracted considerable attention in multimedia and
computer vision researches in recent years. One such research is video
inpainting.Videoinpainting aims to restore missing or tainted regions or remove objects present
in a video sequence from neighboring scenes. The proposed method in video inpainting is object
removal technique based on seam carving algorithm, where the static AVI video type and object
dynamic are used and working video for different number of frames per-second with resolution
(320 pixel by 240 pixel) and (640 pixel by 480 pixel) .The implementation in the proposed seam
carving algorithm for object removal is obvious that discrete Laplacian edge detection filter
gives the highest matching with four videos, which proves that its work is the best in detecting
the energy of a video, and the best accuracy for whole system is (86.57516).

In this research the thermal conductivity of the epoxy resin composites had studied
characterized as operating particle size of filler. SiO2 and MgO are used as filler with three
different particle size (37,75 and 125μm) with volume fraction of 5%. Hybrid composite
samples of both filler were prepared using same value of 2.5% of both in composite. The
result shown enhancement in thermal conductivity value of composites compares with the
pure and incensement with decreased the grain size of particles additives as a nonlinear
relationship. The result given away thermal conductivity of EP/MgO composites better than
the thermal conductivity EP/ SiO composite. The hybrid composite samples gives high values
of thermal conductivity comparing with (Ep/MgO, EP/SiO2) alone for all particle size.

Phthalimide-benzothiazole ligand (L) and their complexes of Hg(II) with diphosphine and
diamines have been prepared. Conductivity measurements show the 2:1 (ion- complex ion)
behavior of the complexes except for [Hg(L)Cl2] (1) complex which was non-conductive. The
Phthalimide-benzothiazole ligand has been observed to be bonded to the Hg(II) ion through the
nitrogen and oxygen atoms as a bidentate chelating ligand, whereas the diphosphine and
diamine ligands have been bonded as bidentate chelating ligands to give a tetrahedral geometry
around the Hg(II) ion.
