This research was carried out in the laboratories of Erbil city on recycled PVC plastic for several times. The plasticizer DOP was extracted from the old plastic to study the extent to which the plasticizer remained in it after a period of time, as well as its exposure to heat of atmosphere. Several experiments were conducted to reach the optimum conditions to obtain the highest percentage of extracted plasticizer and then it was diagnosed by infrared spectrophotometer and thin layer chromatography. The results showed that the extracted plasticizer matches the standard plasticizer. We also performed viscosity measurements and bromine detection. The results showed that increasing the percentage of plasticizer works to increase the flexibility of plastic materials and reduce the degree of softening, knowing that adding the amount of plasticizer depends on the season of the year. This study can be used for the purpose of qualitative improvement of the production of recycled plastic as well as for the benefit of environmental issues.

The Web provides various kinds of data and applications that are readily available to explore and are considered a powerful tool for humans. Copyright violation in web documents occurs when there is an unauthorized copy of the information or text from the original document on the web; this violation is known as Plagiarism. Plagiarism Detection (PD)can be defined as the procedure that finds similarities between a document and other documents based on lexical, semantic, and syntactic textual features. The approaches for numeric representation (vectorization) of text like Vector Space Model (VSM) and word embedding along with text similarity measures such as cosine and jaccard are very necessary for plagiarism detection. This paper deals with the concepts of plagiarism, kinds of plagiarism, textual features, text similarity measures, and plagiarism detection methods, which are based on intelligent or traditional techniques. Furthermore, different types of traditional and algorithms of deep learning for instance, Convolutional Neural Network (CNN) and Long Short-Term Memory (LSTM) are discussed as a plagiarism detector. Besides that, this work reviews many other papers that give attention to the topic of Plagiarism and its detection.

Software Effort Estimation (SEE) is used in accurately predicting the effort in terms of (person–hours or person–months). Although there are many models, Software Effort Estimation (SEE) is one of the most difficult tasks for successful software development. Several SEE models have been proposed. However, software effort overestimation or underestimation can lead to failure or cancellation of a project.
Hence, the main target of this research is to find a performance model for estimating the software effort through conduction empirical comparisons using various Machine Learning (ML) algorithms. Various ML techniques have been used with seven datasets used for Effort Estimation. These datasets are China, Albrecht, Maxwell, Desharnais, Kemerer, Cocomo81, Kitchenham, to determine the best performance for Software Development Effort Estimation. Root Mean Square Error (RMSE), Mean Absolute Error (MAE), and R-Squared were the evaluation metrics considered. Results and experiments with various ML algorithms for software effort estimation have shown that the LASSO algorithm with China dataset produced the best performance compared to the other algorithms.

Language classification systems are used to classify spoken language from a particular phoneme sample and are usually the first step of many spoken language processing tasks, such as automatic speech recognition (ASR) systems Without automatic language detection, spoken speech cannot be properly analyzed and grammar rules cannot be applied, causing failures Subsequent speech recognition steps. We propose a language classification system that solves the problem in the image field, rather than the sound field. This research identified and implemented several low-level features using Mel Frequency Cepstral Coefficients, which extract traits from speech files of four languages (Arabic, English, French, Kurdish) from the database (M2L_Dataset) as the data source used in this research.
A Convolutional Neuron Network is used to operate on spectrogram images of the available audio snippets. In extensive experiments, we showed that our model is applicable to a range of noisy scenarios and can easily be extended to previously unknown languages, while maintaining classification accuracy. We released our own code and extensive training package for language classification systems for the community.
CNN algorithm was applied in this research to classify and the result was perfect, as the classification accuracy reached 97% between two languages if the sample length was only one second, but if the sample length was two seconds, the classification accuracy reached 98%. While the classification among three languages, the classification accuracy reached 95% if the sample length was only one second, but if the sample length was two seconds, the classification accuracy reached 96%.

The antibacterial effect of three selected isolates of Bacillus subtilis (Sar1, Sar2, Sar3) was tested by the agar diffusion method, and the results showed that there was no inhibitory effect of these bacteria against the growth of pathogenic bacteria; Staphylococcus aureus, Staphylococcus haemolyticus Escherichia coli, and Pseudomonas aeruginosa, while the undiluted and half-diluted (200, 100, 50) mg/ml extracts, of the three cultures which are tested by the Agar Well Diffusion method, had varying inhibitory effects towards the growth of these five pathogenic bacteria and more effect on gram-positive compared to its effect on gram-negative bacteria.
Through GC-MS detection of secondary metabolites of Bacillus subtilis (Sar1) extract, which were selected because they are identical to Bacillus subtilis bacteria contained in the standard GeneBank with a percentage of (95)%, it was found that they consist of (33) chemical substances according to the number of peaks produced. After injecting the extract into the GC device, and when this information was entered into the MS device, it was diagnosed by its names with the calculation of its molecular weight and the amount of area it occupies as a percentage within the used extract understudy.

Insecticides are chemical compounds that extensively used in agriculture for pest management, urban and household as well as in medicine to control different diseases such as typhus, malaria and others. The purpose of this study was to investigate the toxic effects of compound insecticide (Acetamiprid and Thiamethioxam) on develop-ment of Ross 308 Broiler chick embryo. 250 fertile eggs were divided into 6 groups two of them were control group, negative and positive control were injected with distilled water and the other were injected with 100µl/egg, into the yolk sac, containing Acetamiprid and Thiamethioxam (360, 540, 900 and 1800ppm). The morphological characteristics were studies on day 10th and 21st day of incubation. The fourth doses caused reduction in the embryos weight and significant increase in the mortality. In addition, there were clear abnormalities indicated on both days (10 and 21) including over growth in the brain, twisted cleft beak, wry neck eye deformation, ectopia visceral, delayed retraction of yolk sac, abnormal limbs, and broken legs. Microscopically, examination of liver tissue revealed on 10 day as well as 21 day to alterations in the hepatic cells including necrosis and degeneration enlarged and congested central vein and sinusoidal spaces and infiltrations of leucocyte and Kupffer cells activation. To conclude, the current study revealed that Acetamiprid and Thiamethioxam caused significant morphological and histological effects in chick embryo Ross 308.

In this paper an improved phonon imaging for GaP has been calculated, this crystal is one of III-V group. In the presence of piezoelectric properties, the computation treatment is based on increasing the number of points in the reduced Brillouin zone and increasing the size of the phonon image matrix. The phonon images can be calculated by large number of points in the reduced Brillouin zone which represent the wave vectors and these vectors can be transformed to group velocity vectors using Christoffel equation, these set of group velocity vectors can be projected in a certain direction to form the phonon image. A program was prepared in MATLAB language to calculate these images by determining the number of points in the reduced zone and determining the size of the matrix that represents the phonon images in addition to the direction of the projections. To calculate the phonon images in the presence of the effect of the piezoelectric properties, it is through the presence of the k44 factor, which indicated of the influence of the piezoelectric properties on the phonon images. The results showed that the size of the image matrix is more effective factor than the number of points in the reduced Brillouin zone especially when the number of points is greater than 8×〖10〗^5 points, and when the number of points less than 〖10〗^4 points all the obtained phonon images is not clear.

Packets queuing and scheduling in network routers is a key point of overall network performance. Many applications, especially applications require Quality of Services (QoS), need techniques to pass their packets throughout routers and control and/or avoid congestions in highly congested routes. Therefore, many Active Queue Management (AQM) algorithms have been developed to avoid or control congestion in routers and provide fairness among traffic flows. This paper provides an extensive evaluation performance analysis of three well-known AQM algorithms including RED, REM and traditional Drop-Tail with QoS application requirements. The evaluation performance is conducted by employing network simulator version 2 (NS2). The network performance is measured with Voice over Internet Protocol (VoIP) traffic and three performance metrics including, throughput, latency, and PSD (Probability of Sequential Drop). The analysis shows no AQM algorithm achieve all the VoIP QoS requirements, A new AQM is needed to fulfil QoS requirements and manage queue to handle unresponsive flows.
