1,3- Oxazepines, benz [1,2-e] [1,3]-oxazepines, and 3- nitrobenz [1,2-e] [1,3] - oxazepines were reacted with ammonia derivatives, H2N-Z .. to give 1,3 – diazepine -4,7- dione, benzodiazepine - 4,7- dione, and 3 – nitrobenzo -1,3- diazepine - 4,7- dione, respectively.
The effect of SiO 2 ) Silica) on the dielectric and physical properties of Mnx-Ni1 -xFe2O4 ،، X=0.5 is studies. The samples are prepared by the conventional manufacturing
method. We found that the physical and dielectric properties of Mn-Ni ferrite change
considerably with the substituent samples .the variation of dielectric constant as a function of
frequency of ferrite system decrease with frequency increases and increase with the increase
the concentration of SiO 2 . It was found that the increase of SiO 2 concentration of all our
samples produce an increase in mass density and decrease with porosities
A complexified adjoint representations of the complexification Lie algebras associated with the special orthogonal group SO(3) and special linear group SL(2,₵) have been obtained. A new representation of their tensor product is naturally arisen and computed in details.
Captopril is an angiotensin converting enzyme inhibitor (ACEI) used to treat hypertension,
congestive heart failure, and myocardial infraction.
The only dosage form available for captopril is the plain tablet in strength of 12.5,25,50 and 100mg
tablet.
This investigation is concerned with factors affecting the formulation of captopril as a plain
tablet dosage form of 50mg. Many trials were made to prepare satisfactory tablets for the drug by
using wet – granulation methods with various additives. It was found that poly vinyl pyrrolidone
(P.V.P.) as binder gave the most satisfactory tablets. At the same time a shorter disintegrantion time
and slower dissolution rate were obtained with the addition of starch
Being a doctoral student is not easy because it presupposes having a number of technical skills, among which digital skills, defined by the European Commission (2006) as "the safe and critical use of the technologies of the society of the information". and the variety of digital use in the personal and professional context, allows us to ask the question that any doctoral student should master and acquire in terms of digital skills? And on what basis can we define these skills?
In this work we expect to develop a baseline of digital skills, is a document that includes the set of essential digital skills that represents a fundamental tool for the doctoral student who can in no way bypass it. And for this, we conducted interviews with ab
This study detects the presence of the most important steroidal sapogenin “Tigogenin†in the leaves of Yucca aloifolia widely cultivated in Iraq. The absence of any study concerning the Tigogenin content of this medicinal plant in Iraq, and the industrial importance of Tigogenin depending on its role as a precursor in the synthesis of some steroidal drugs, acquired this study its value. This study concerned with extraction, identification, isolation, and purification of Tigogenin from the leaves of Yucca aloifolia. Extraction of this compound was carried out using two methods. Identification of this compound was done using thin layer chromatography (TLC) where different solvent systems had been tried. Liberm
... Show MoreThis research presents the results of the tests of the physical, chemical and biological treatments performed on the industrial effluent of Al-Rashid Factory for vegetable oils during January to July, 2010. Some environmental parameters such as temperature, electrical conductivity(ec), Biological oxygen demand(bod), chemical oxygen demand(cod), total suspended solids(tss), dissolved oxygen(o2) and total dissolved solids(tdc) have been investigated. The study shows that the industrial effluent contains a percent of organic pollution and in different values, and that it is responsible for the (bod), which records (5.15-67)ppm, while the (cod) ranges between (25-170.5)ppm, the (ec) values range between (

,75 ,100 mg) of pellets of this rodenticide. The results showed n significant decrease (p< 0.0 I ) in testicular weight and volume, epididymal ( head and tail) weight and numbers of different spermatogenic cells. The rodenticide caused a significant decrease in sperms concentration and a significant increase in dead and abnormal sperms in testes and epididymis.
The presence of the most important steroidal sapogenin “Tigogenin†in the leaves of Agave americana cultivated in Iraq was detected. The absence of any study concerning the Tigogenin content of this medicinal plant in Iraq, and the industrial importance of Tigogenin depending on its role as a precursor in the synthesis of some steroidal drugs, acquired this study its value. This search include extraction, isolation, purification and dentification of Tigogenin from the leaves of Agave americana. Extraction of this compound was carried out using two methods. Identification of this compound is carried out by using thin layer chromatography (TLC) where three different mobile phase have been use
... Show MoreThe species Cyclops varicans G.O.Sars (Which was recorded for the first time in Iraq ) was chossen to study the effect of photoperiods on the species reproduction growth . The chossen photoperiods were 0:24 , 12: 12 , and 24 : 0 L.D. The data showed obvious statistical effect of photoperiods specially 24 : 0 L.D. on the mean of clutch size , produced eggs , no. of nauplei , transformation time of nauplius I to copepodid I and transformation time of copepodid I to adult stage . The data also showed uneven effects of photoperiods on the number and maturation period of both males and females . Temperature , transparency , PH , and electrical conductivity also have been studied for the ad

In order to assess the possible ecological causes of the incidence and the prevalence of visceral leishmaniasis, in one of the well-known foci of the disease in the central region of Iraq. It was found that the human dwelling position and ecological factors affect the infection with this disease.
