Autism is considered as one of the most developmental problems in the world that interfere with children growth and affect their social ,emotional and cognitive development child with autism used to be normal in his growth but in his development parents started to notice that their child characterize by loneliness and withdrawal himself from the surrounding world with some mannerism behaviors these characteristics used to be manifested children during the 1^st three year of their life . It appears, one in every 500 birth (The American International Institution for child health 1997. and it would be less in females than makes at 1/4 percent .

Aim is to build the autism scale for children , and the total population of (Rami,AL-amal,AL-saadah) institutes for handicapped in Baghdad were 447 children (boys and girls) (400)children (boys and girls ) were chosen randomly to fulfill the requirement of the study, children were from3-13 years old at academic year 2006/2007 . 210 of them Males and 237 females. (18) teachers from the above institutes chosen to apply ,.

The scale to be applied for autistic children is consist of five elements ,1^st element is (language and communication is weighted 27% , 2^nd element is visual understanding of the child weight 13% ,3^rd element is social adaptation of the child that weight 20%,4^th is effervescence behavior weight 20% , and finally the 5^th element which is gross and fine motor skill assessment that weight 20%, ). and it has been (90) items were formulated and then (10) of the formulated items were omitted and only (80) items were discovered to be reliability and validity , Pearson correlation coefficient while the scale reliability has been done in two ways ( test Re test , Alfa Cronbach) were used to analyze the result. and the standard error of the scale has been extracted which leads for some recommendation and suggestions of them is to benefit of the research indigenizing autism children in primary schools .

Cytotoxicity of Miltefosine against Leishmania majorPromastigotes

Leishmaniasis has poor vaccination trials and the available drugs have side effects on patients. Therefore

development ofnew chemicals is important for public health. Miltefosine is the first drug used for oral treatment of visceral leishmaniasis.Previous studies approved that miltefosine is an effective treatment against visceral leishmaniasis

the visceral form ofLeishmania

and also on L. major

the cutaneous form of Leishmania. Here

we investigated the in vitro cytotoxicity ofmiltefosine on the procyclic promastigotes forms of L. major. Different concentrations of miltefosine were investigatedagainst the flagellated form of L. major

and results showed that miltefosine has inhibited the in vitro proliferation of theparasite

approving the cytotoxic effect of the compound on Leishmania

EC50 was determined after 24 hours exposure forthe drug and it was 1.54 μM. Our findings indicate that miltefosine has a cytotoxic effect on the insect stage of the old worldL. major and can be a new anti-Leishmanial drug

Pulse Profile Rule in Laser Heating of Opaque Targets in Air

A theoretical model is developed to determine time evolution of temperature at the surface of an opaque target placed in air for cases characterized by the formation of laser supported absorption waves (LSAW) plasmas. The model takes into account the power temporal variation throughout an incident laser pulse

(i.e. pulse shape

or simply: pulse profile). Three proposed profiles are employed and results are compared with the square pulse approximation of a constant power.

Novel dichloro (bis {2-[1-(4-methylphenyl)-1H-1, 2, 3-triazol-4-yl-κN3] pyridine-κN}) metal (II) coordination compounds of seven transition metals (Mn, Fe, Co, Ni, Cu, Zn and Cd)

The 1

3-dipolar cycloaddition “click” reaction between an azide and an alkyne to give a 1

3-triazole was reported by Huisgen in 1961 [1]. In 2002 the Copper(I)-catalyzed Azide-Alkyne Cycloaddition (CuAAC) to prepare a 1

[3]. The existence of relatively basic nitrogen atoms in the 1

2

3-triazole rings

and the possibility of introducing additional donor groups in the substituents (Fig. 1)

made the CuAAC “click” reaction an attractive method to prepare differently substituted 1

2

3-triazoles. These compounds have been used as ligands to coordinate to various metal ions that display a range of applications such as in electrochemical and photochemical studies

in supramolecular chemistry

magnetism

metal-ion sensing and catalysis [4]. The reasons for the success of the “click” reaction

is that it is easy to carry out and is widely applicable. It is not affected by a variety of functional groups

and can be carried out with a variety of Cu(I) catalysts and solvents

including aqueous conditions. The Cu(I) catalysts overcome the high activation energy barrier of the non-catalyzed Huisgen reaction by changing the mechanism of the reaction. A large variety of copper catalysts can be used for the CuAAC reaction

on condition that the maximum concentration of Cu(I) species is generated during the reaction. The pre-catalyst can be a Cu(II) salt (usually CuSO4) together with a reducing agent (often sodium ascorbate) or a Cu(I) compound in the presence of a base or amine ligand and a reducing agent to prevent oxidation to Cu(II). Some strong oxidising cupric salts or complexes such as Cu(OAc)2 also work. The solvent is very flexible from organic to aqueous

with the most commonly used combination water + an alcohol (t-BuOH

MeOH or EtOH). The key role of the solvent or solvent mixture is to solubilize the substrates and Cu(I) catalyst in order to ensure rapid reactions. Such aqueous conditions are very useful for biochemical conjugations

as well as for organic syntheses. We recently reported on the synthesis of a series of differently substituted 1

The effect of ground motion characteristics on the fragility analysis of reinforced concrete frame buildings in Australia

The seismic performance of buildings can be assessed through fragility analysis as it yields the probability of the demand exceeding the capacity at a specified level of intensity. Although it's well-identified that earthquake uncertainties dominate the fragility characteristics

the influence of the characteristics of the earthquake on the fragility analysis is not well investigated. This study aims to compare the effect of earthquake characteristics on the fragility values of typical buildings in Australia. To achieve this

a typical reinforced concrete building is selected and modeled using a finite element approach. Various ground motion suites

such as near-fault

far-fault

and long-duration are selected

and the fragility analysis has been carried out for each ground motion suite. It is observed that the variation in the median values of the collapse fragilities can be as high as 48% between short-duration and long-duration ground motions

and about 40% between long-duration and pulse-like ground motions.
