EVALUATION AND PERFORMANCE COMPARISON OF MOLD BOARD AND DISC PLOW IN SOILS OF CENTRAL IRAQ
...Show More Authors

The experiment was conducted to evaluate and performance comparison for moldboard and disk plows in central of Iraq in 2011. Three factor were used in this study included Two types of plows included moldboard and disk plows which represented main plot , three forward speeds of the tillage was second factor included 1.85, 3.75 and 5.62 km / h which represented sup plot , and three levels of soil moisture was third factor included 21 , 18 and 14 % to determined data actual plow depth , Practical productivity, Volume of disturbed soil, Field efficiency , Slippage percentage in silt clay loam soil with depth 22 cm were studied in the experiment Split – split plot design under randomized complete block design with three replications using Least Significant Design was used . Mold board plough recorded best practical productivity was 0.3118 ha/hr , volume of disturbed soil was 629.77 m3/hr and field efficiency was 59.85 % , while disc plough recorded higher actual plow depth 21.02 cm and slippage percentage was9.71 % . Increasing forward speeds of the tillage from 1.85 to 3.75 then to 5.62 increasing slippage percentage from 6.39 to 8.26 then to 12.22 % , practical productivity from 0.1421 to 0.2845 then to o.4180 ha/hr and volume of disturbed soil from 299.89 to 592.38 then to 838.24 m3/hr , while decreased actual plow depth from 21.13 to 20.86 then to 20.08 cm and field efficiency from 58.98 to 58.21 then to 57.07 % . with decrease soil moisture from 21 to 18 % decrease actual plow depth from 20.92 to 20.70 cm and slippage percentage from 10.58 to 7.29 % , and increase practical productivity from 0.2712 to 0.2923 ha/hr, volume of disturbed soil from 562.01 to 598.98 m3/hr and field efficiency from 55.94 to 60.31 % . While continues decrease from 18 to 14 % decrease actual plow depth from 20.70 to 20.46 cm, practical productivity from 0.2923 to 0.2811, volume of disturbed soil from 598.98 to 569.52 m3/hr and field efficiency from 60.31 to 58.01 % , and increase slippage percentage from 7.29 to 9.00 % .

Public exposure to news satellite channels and its relationship to levels of preference and evaluation of programs: Survey study on a sample of the audience of Baghdad City Cente
...Show More Authors

The media, especially the satellite channels in our time, are one of the most important pillars of daily life, public and private, for society and people, and are considered by sociologists and sociologists as one of the most important factors of social upbringing and the most important, as a result of the technological and technological development of the media as well as increasing their numbers and vertical and horizontal expansion locally, As well as entering into the lives of individuals and people and leading them to important sites within their interests and preferences, not to mention the long time spent exposure to those media and benefit from the programs offered or broadcast. , The problem of this research is that there is a l

Static Performance Characteristics Of Vortex Rate Sensor
...Show More Authors

The vortex rate sensor is a fluidic gyroscope with no moving parts and can be used in very difficult conditions like radiation, high temperature and noise with minimum cost of manufacturing and maintenance. A vortex rate sensor made of wood has been designed and manufactured to study theoretically and experimentally its static performance .A rig has been built to carry out the study,
the test carried out with three different air flow rates (100, 150, and 200 l/min).The results show that the relation between the differential pressure taken from the sensor pickoff points and the angular velocity of the sensor was linear.The present work involved theoretical and experimental study of vortex rate sensor static characteristics .Vortex rat

Performance of quadrilateral perforated prestressed concrete rafters
...Show More Authors

This study focuses on the behavior of simply supported perforated prestressed concrete rafters (PPCRs) under single midspan monotonic static loading. The experimental program consisted of testing seven specimens; one solid (control) rafter, and six perforated with quadrilateral openings. The main investigated variables are the number and height of the openings. The test findings indicate that, in comparison to the solid rafter, the presence of quadrilateral openings in the PPCRs led to reducing the load capacity by (4.3-36%) and increase the midspan deflection at ultimate by (14.8-33%). Also, increasing the number of concrete posts between openings resulted in increasing the failure load and decreasing the deflection at all stages o

Ore Petrography, Mineralogical and Chemical Composition of New Iron Meteorite (Al-Sherqat Meteorite) from Iraq
...Show More Authors

The meteorite with a single total mass of 630 gm as a visible meteorite has fallen on 22 March 2021, at 10:00 a.m. in Al-Sherqat subdistrict within Salah Al-Din, northern Iraq; and therefore, was named Al-Sherqat meteorite by the authors. It is characterized by a uniform structure of coherent and medium degree of malleability. It is of a well-crystalline structure and not homogeneous in composition. The Al-Sherqat meteorite is composed of metallic phases of 7.6 gm/cm3 density exhibiting an oriented intergrowth of kamacite (α-FeNi) with taenite showing a Widmanstätten pattern on an etched polished section with the finest octahedrite kamacite bandwidth of less than 0.2 mm. It is composed of Fe (86.9 wt%), Ni (9.63 wt%), P (1.31 wt%)

CALCAREOUS NANNOFOSSILS AND CHEMOSTRATIGRAPHY OF THE EARLY APTIAN OCEANIC ANOXIC EVENT 1A FROM NORTHERN IRAQ
...Show More Authors

   Calcareous nannofossils were documented from the upper part of the Cretaceous Balambo Formation in northern Iraq with the aim of determining an evidence for the Oceanic Anoxic Event. A detailed investigation of the calcareous nannofossils led to the identification of twenty-four species. Regarding these data, Discolithus litterarius (Górka, 1957) was identified at the studied interval with the age of Early Aptian.

   Early Aptian assemblages are dominated by nannoconids that drop sharply within the D. litterarius nannofossil zone, which may be related to the nannoconid crisis recorded in the Early Aptian in the other parts of the world. This event is coincided by a decrease in CaCO3<

ABSTRACT Background: Dental anomalies of teeth are major issue that contributes to dental problems encountered in general practice. The aim of this study is to measure the prevalence of dental anomalies and the associated etiological factors among 15 years old students in Basrah city –Iraq. Materials and methods: The total sample composed of 1000 students (435 males and 565 females) from urban area selected randomly from different high schools in the city. Diagnosis of dental anomalies were recorded by present or absent, diagnosis and recording of enamel defects were done according to the criteria of WHO (1997).
