In this paper, we characterize the unitary composition operator pC on the Hardy space 2H where p is a special automorphism of a unit open disk U such that. In addition to we study the compactness and essential normality of and give some other partial results.

For a connected topological space M we define the homeomorphism and period noncoincidence indices of M, each of them is topological invariant reflecting the abundance of fixed point free self homeomorphisms and periodic point free self maps defined on M respectively.
We give some results for computing each of these indices and we give some examples and some results relating these indices with Hoffman index.

Results of laboratory investigation in larvae of common carp fish , Cyprinus carpio exposed to Sumicidin ,Fenvalerate, and its residue, normally used as air sprays to control insects, that this insecticide was toxic to fish larvae. After exposure to the insecticide, some larvae were immediately killed ; others showed abnormal behavior and eventually either died or recovered depending on sumicidin dose received.The LC50 of Sumicidin to fish larvae exposed to insecticide during a period of 96 hour was 0.024 mg/L for fish 4-6 gm

The aim of this study was intend to study the effect of rifampicin drug on the level of liver enzymes in rabbits. Eight rabbits were used in this experiment and they were divided into two groups. The first group (control group) was administrated with 15 mg /ml/day normal saline for 35 days, while the second group (treated group) was administrated with 15 mg/ml/day for 35 days of rifampicin capsule (300 mg/kg). This study examined the influences of rifampicin drug on the concentration of Aspartate aminotransferase (ALT), Alanine aminotransferase (AST), total bilirubine and alkaline phosphates in rabbit sera. The results showed that there were a significant increase (p<0.05) in ALT concentration in rifampicin treated group compared with

The algal species Secenedesmus quadricauda was used to remove nickel ions from contaminated water (under laboratory conditions). It was exposed to different concentrations of nickel (2, 4, 6 and 8) ppm in order to measure it capacity to remove and tolerate this metal.
The results showed that the alga was able to remove this metal with percentages of
98, 53.5, 55.33 and 43% for the concentrations 2, 4, 6 and 8 ppm, respectively, in
the eighth days of the experiment period, while this ability was decreased in the
fourteen days of the experiment period to: 80, 43.25, 36.83 and 26.62 % for the
concentrations 2, 4, 6, and 8, ppm respectively, as a result of death for some algal
cells. So, it was concluded that th

An algorithm to recognize distorted Machine and handwritten characters is proposed. It uses a feature point extraction-based recognition approach. A new verification scheme, which deals with this problem, is presented. A new feature extractor set is introduced. This research explores best sets of feature extraction techniques and studies the accuracy and speed of the suggested procedures. Finally, experimental results on one database are presented, their results showing the robustness of the algorithm using small database.

The ongoing changes in computer performance are affecting the efficiency of
string searching algorithms. The size of main memory in typical computers
continues to grow, but memory accesses require increasing numbers of instruction
cycles.
One of the most important data structure which is used to improve the string
searching is the Trie tree.
The name Trie comes from the word “retrieval”. This data structure dose not store
the data as specific elements, but rather as a path through the tree.
This research aims to improve the performance of the Trie tree by using a proposed
sample function in trie algorithm which improve space utilization and decrease the
number of the search levels in

Homologues series of some derivatives of 3, 5-(4-substituted phenyl)-l, 2, 4-
oxadiazole were synthesized and their phase behavior was studied. Introduction of
the pentagonal hetero aromatic ring leads to significant changes in mesomorphic
behavior. The synthesized compounds exhibit nematic phase.

In this paper we prove the following result. Let R be a non-commutative prime*-
ring of characteristic different from 2, then R is normal *-ring if and only if there
exists a nonzero Jordan*-derivation d: R→R be which satisfies [d(x), x] ∈ Z(R) for
all x ∈ R, and [d(h),s] ∈ Z(R) or [d(s), h] ∈ Z(R) for all h ∈ H(R), s ∈ S(R).

Weil das Wort als Kern der Sprache ist und es als das wichtigste Element betrachtet wird, beschäftigten sich die Sprachwissenschaftler nicht nur zur Zeit sondern seit hunderten Jahren mit dem Wort und seiner Bedeutung. Deswegen wurden viele Forschungen darüber geschafft.

Aus der Wichtigkeit des Wortes wird in dieser Forschung  besonders vom Wort gesprochen, das mehrere Bedeutungen hat und das problematisch bei der  Übersetzungsprozess sein kann.

The present work aims to study forward osmosis process using different kinds of draw solutions and membranes. Three types of draw solutions (sodium chloride, sodium formate, and sodium acetate) were used in forward osmosis process to evaluate their effectiveness with respect to water flux and reverse salt flux. Experiments conducted in a laboratory-scale forward osmosis (FO) unit in cross flow flat sheet membrane cell.  Three types of membranes (Thin film composite (TFC), Cellulose acetate (CA), and Cellulose triacetate (CTA)) were used to determine the water flux under osmotic pressure as a driving force. The effect of temperature, draw solution concentration, feed and draw solution flow rate, and membrane types, were studied with

The removal of boron from aqueous solution was carried out by electrocoagulation (EC) using magnesium electrodes as anode and stainless steel electrodes as cathode. Several operating parameters on the removal efficiency of boron were investigated, such as initial pH, current density, initial boron ion concentration, NaCl concentration, spacing between electrodes, electrode material, and presence of carbonate concentration. The optimum removal efficiency of 91. 5 % was achieved at a current density of 3 mA/cm² and  pH = 7 using (Mg/St. St. ) electrodes, within 45 min of operating time. The concentration of NaCl was o. 1 g/l with a 0.5cm spacing between the electrodes. First and second order rate equation were applied to study adsorp

            The concept of narration has taken an aesthetic field farther than the primitive human act which was imposed by the necessities of social communication in an ancient historical period. The research addressed the research problem. The importance of the research lies in connecting the concept of narration with the theatre directing elements. The research aims at discovering the narration fields in the theatre directing represented by the perceived videos, audios and motions. The research time limit was (2014).  The theoretical framework is divided into three chapters:

Background: Non-traumatic Intracerebral Hemorrhage (ICH) results from rupture of blood vessels in the brain. ICH categories can also be considered as being either lobar in location or within the deep white matter. Although hypertension is a major risk factor for ICH in general[11], it is commonly considered to be associated more with patients having deep than with those having lobar haemorrhage.
Objectives: We investigate the relationship between hypertension and deep versus lobar intracerebral hemorrhage (ICH).
Methods: a retrospective review of records of 163 patients aged 18-89 years admitted to Al-Kadhimiya Teaching Hospital (January 2008 - October 2010) and diagnosed with ICH.
Results: There was no significant relationship
