This study was conducted in the animal farm of the College of Agricultural Engineering Sciences/ University of  Baghdad/ Iraq, from 23 march 2014 to 23 may 2014 to investigate the effect of  two levels of roughage to concentrate ratio on qualitative and quantitative characteristics of Holstein Friesian veal’s, by studying the traits of three major muscles (longissimus dorsi LD, biceps femoris BF and semimembranosus SM). Two equal groups of Holstein Friesian veal’s  were used. Each group was consilted of five veal’s at eight months old and weighted 228.800 ± 21.221Kg and 227.800 ± 9.167

A field experiment was carried out in summer season 2024  at one field  of the Agricultural Engineering Sciences College, University of Baghdad, in order to study the impact of organic and phosphate fertilization plus foliar application  with the L- glutamic acid, on growth and yield of cowpea (Vigna unguiculata L.). The experiment was laid out in a randomized complete block design (RCBD) with split-plot arrangement and three replicates. The experiment consist three factors, three levels of organic fertilizer (cattle manure) at rates 0, 20, and 40 Mg ha⁻¹; three levels of phosphate fertilizer in the form of diammonium phosphate (DAP, 20% P) at a rate 0, 75 and 150 kg ha⁻¹, and foliar aaplication

The best proximity point is a generalization of a fixed point that is beneficial when the contraction map is not a self-map. On other hand, best approximation theorems offer an approximate solution to the fixed point equation . It is used to solve the problem in order to come up with a good approximation. This paper's main purpose is to introduce new types of proximal contraction for nonself mappings in fuzzy normed space and then proved the best proximity point theorem for these mappings. At first, the definition of fuzzy normed space is given. Then the notions of the best proximity point and - proximal admissible in the context of fuzzy normed space are presented. The notion of α ̃–ψ ̃- proximal contractive mapping is introduced.

Background: The best material for dental implants is polyetherketoneketone (PEKK). However, this substance is neither osteoinductive nor osteoconductive, preventing direct bone apposition. Modifying the PEKK with bioactive elements like strontium hydroxyapatite is one method to overcome this (Sr-HA). Due to the technique's capacity to provide better control over the coating's properties, RF magnetron sputtering has been found to be a particularly useful technique for deposition. Materials and methods : With specific sputtering conditions, the RF magnetron technique was employed to provide a homogeneous and thin coating on Polyetherketoneketone substrates.. the coatings were characterized by Contact angle, adhesion test, X-ray

Determination of soil cation exchange capacity (CEC) in lab is cumbersome, time consuming, and costly. Accordingly, this article attempted to formulate pedotransfer functions for predicting it using some soil physical and chemical properties e.g., sand (SA), silt (SI), clay (CL), organic matter (OM) and calcium carbonate (CC). This research included four steps: preparing soil database; selecting independent variables which are related to CEC value; formulating models using NCSS 12.0.2 software, and the last step is to achieve specific objective of the research which is the comparsion among models by a series of efficiency criteria: root mean square error (RMSE), Nash-Sutcliffe model efficiency coefficient (EF), average absolute p

During the last quarter century, many changes have taken place in the tanks industry and also in the materials that used in its production، while concrete is the most suitable material where concrete tanks has the benefits of strength, long service life and cost effectiveness. So, it is necessary improvement the
conventional concrete in order to adapt the severe environment requirements and as a result high
performance concrete (HPC) was used. It is not fundamentally different from the concrete used in the past, although it usually contains fly ash, ground granulated blast furnace slag and silica fume, as well as
superplasticizer. So, the content of cementitious material is high and the water/cement ratio is low. In this
stu

This research was aimed to study the problems related to fish farming and the risks that they face.  Diyala Governorate was chosen as an applied model for measuring risk facing fish farmers. Research data were collected according to the random sample method, which included (30%) of all fish farming projects in Diyala Governorate. This sample has included 28% of the total fish farming projects in fish ponds and (31.5%) of the total Fish farming projects in cages through a questionnaire prepared for this purpose. The study focused on analyzing the behavior of fish farmers of the research sample towards risks by adopting a safety model in the form of the risk avoidance criterion (K_(s)(.The production functions for fi

This study was conducted to investigate the hypolycemic effect of the aqueous
extract and some active ingredients of Nigella Sativa seeds in normal rabbits. Twenty
four male rabbits were divided into six equal groups. The first five groups were received
by gavage needle 160,240,320,400 and 480 mg/kg B.W. of the aqueous extract, while
the sixth group which served as control received normal saline solution. After two hours
of administration, the group which received 320 mg showed the lowest blood sugar level
as compared to control and other treated groups. This dose was considered for the next
studies.
Lectin was isolated from Nigella Sativa seeds by 0.2M phosphate buffer containing
0.15M NaCl at pH 7.0, and the

Recent research have aimed to know the effect of rational inquiry strategy on acquisition basic science processes for second intermediate students in physics. To verify the aim of this research , the researchers added the following zero hypotheses : No statistically significant differences at the level of significance (0.05) between the students mean scores of the two groups on basic science Processes test. The research was carried out on the second intermediate grade male students in Alam Al Yakeen school in Baghdad; belong to Education Directorate Al- Karkh/2, for the Academic Year (2014-2015) A.D. Prepared research requirements included ] selected the scientific subject chapters (6,7,8,9) from physics textbook, the formulation of beha

The composites were manufactured and study the effect of addition of filler (nanoparticles SiO2 treated with silane) at different weight ratios (1, 2, 3, 4 and 5) %, on electrical, mechanical and thermal properties. Materials were mixed with each other using an ultrasound, and then pour the mixture into the molds to suit all measurements. The electrical characteristics were studied within a range of frequencies (50-1M) Hz at room temperature, where the best results were shown at the fill ratio (1%), and thermal properties at (X=3 %), the mechanical properties at the filler ratio (2%).
