This paper investigates the modal analysis of vibration of Euler-Bernoulli beam subjected to concentrated load. The governing partial differential equation was analysed to determine the behaviour of the system under consideration. The series solution and numerical methods were used to solve the governing partial differential equation. The results revealed that the amplitude increases as the length of the beam increases. It was also found that the response amplitude increases as the foundation increases at fixed length of the beam.

The average concentration of radionuclide’s in the various banana samples were collected from being the most popular markets in Baghdad city - Iraq were measured by use Sodium Iodide Thallium [NaI(Tl)] detector. The radionuclide’s observed with reliable regularity belonged to the series-decay naturally occurring radionuclide’s headed by 232U and 232Th as well as the non-series nuclide, 40K and 137Cs. The average concentration of 40K was found the least average concentration value recorded as876.74625Bq kg-1.The average concentration of 238U was 28.6425Bqkg-1for ²³²Th, it was found to have the average concentration 14.1805 Bqkg-1. The cesium concentration in the sample was found in the healthy range.

تتجه العمليات الاجتماعية بوصفها نموذج للتفاعل نحو التنميط بمرور الوقت. وبالتالي، فإن التغير الزمني والاستمرارية هما سمات ثابتة وأساسية لحالة الإنسان. ومن هذا المنظور، فإن الاستعمال النموذجي لمفهوم التغير (الذي يتم تطبيقه فقط عندما يتغير الوضع الطبيعي بشكل جذري وسريع) ينطوي على العديد من الادعاءات المثيرة للقلق، بما في ذلك فكرة أن الركود أمر طبيعي وأن التغير فقط يحتاج إلى تفسير. والحقيقة ان البديل هو التفك

إنّ القصّة من أحبّ الفنون الأدبيّة عند الأطفال، ومن أنجحها في تحقيق الأهداف التربوية المنشودة، بعيدًا عن التوجيهات والأوامر والنواهي المباشرة. ومن أهم تلك الأهداف: الاجتماعيّة والنفسيّة والأخلاقيّة والإنسانيّة. ويعدّ تناول موضوع (أصحاب الاحتياجات الخاصة) من الموضوعات الاجتماعيّة والإنسانيّة المهمّة، التي يجدر بأديب الطفل أن يعالجها في قصصه. وعليه حينها أن يكون حذرًا جدًّا في معالجة الأفكار التي يطرحها؛

The objective of the present study is to determine the anti-obesity effects of Akkermansia munciniphila  on some biometric measurements. 40 patients were divided into two groups, each with 20 patients; G1 group consumed the probiotic of A. munciphila   and G2   consumed placebo capsules. The results  showed significant effects on the body weight (p≤ 0.001), which was reduced by a range of -2.29 to -0.7, whereas non-significant differences were observed in the Waist circumferance  . The study also showed significant differences (p≤0.001) between the two groups in the levels of cholesterol (287 vs. 285 mg/dl) , whereas the level of  Triglyceride  significantly  decrease

Localized surface plasmons (LSPs) are a potentially valuable property for the practical use of small size metallic particles. Exploiting the LSPs in metallic nanoparticle (NP)-based solar cells was shown to increase the efficiency of solar panels. A large extinction cross section of NPs allows for high scattering of light at the surface of the panel, which reduces the panel thickness, allowing for small size and low-cost solar cells. In this paper, the extinction cross-section of spherical nanoparticles is studied and simulated numerically. Surface plasmons were first modeled using the Drude’s model then the scattering and absorption cross-sections were derived. Commercial3D simulation software was used to model the near field dis

In this paper, the dynamics of a three species food web model consisting of
producers, primary consumers and omnivory is studied analytically as well as
numeri-cally. The existence of equilibrium points and local stability analysis
for this model is carried out together with a bifurcation analysis. The
occurrence of hopf bifurcation is also investigated. The persistence conditions
of the food web model are established by using average Lyapunov function.
The global stability analysis of the food web model is also presented with help
of Lyapunov method. Finally, in order to confirm our analytical results,
numerical simulation is carried out for suitable choices of parameters values. It

     The behavior of rare earth elements (REE) in phosphate coprolites; deposited in marine upwelling shelf system (Iraq) and a condensed section of the intracontinental basin (Czech Republic) is compared and discussed in the present study. The eight coprolite samples show that the REE incorporated in the apatite of these phosphatized faecal trace fossils have significantly different behavior in the two sedimentary regimes and hold the REE source’s signature in the local sedimentary conditions. The behavior of heavy REE, light REE, Ce-anomaly and shale-normalized ratios of Ce/La, Sm/Yb and Pr/Ce can be mainly attributed to REE fractionation at the source. In contrast, middle REE enrichment may be attributed to local fractionation b

The aquatic Heptageniidae family of Ava-sheen branch (Greater Zab Tributary) in Duhok Governorate/ Iraq was studied. Samples were collected using Surber stream sampler to study their diagnostic morphological characteristics and molecular phylogenetic profile using a nuclear gene 16s ribosomal RNA. The morphological and molecular identification supported that the three species, Epeorus longimanus, Heptagenia elegantula and Ephemerella cornutus belong to Heptageniidae family, while the molecular results also confirmed the monophyletic origin of these three genera.

Ad'Daimah Field is a structural trap with a proven gas condensate reservoir in limestone. The Yamama Formation is the faulted anticline that makes up the field. Thirteen seismic lines were used for this study, with one well (Da-1). Velocity maps derived from the velocity model were used to construct time and depth maps. Certain stratigraphic features were present in the examined reflector, according to seismic interpretation in the region. In the research area, certain distribution mounds and continuous sand lenses in more than two-dimensional seismic lines were seen. These activity components offer a logical justification for the distribution of hydrocarbons in the study region. The major normal fault of (NW-SE) trending and minor norma

In this paper an accurate Indian handwritten digits recognition system is
proposed. The system used three proposed method for extracting the most effecting
features to represent the characteristic of each digit. Discrete Wavelet Transform
(DWT) at level one and Fast Cosine Transform (FCT) is used for features extraction
from the thinned image. Besides that, the system used a standard database which is
ADBase database for evaluation. The extracted features were classified with KNearest
Neighbor (KNN) classifier based on cityblock distance function and the
experimental results show that the proposed system achieved 98.2% recognition
rate.
