Avoidance of Contract as a Remedy under CISG and SGA: Comparative Analysis

This article deals with fundamental breach in the 1980 United Nations Convention on Contracts for the International Sale of Goods (CISG) and the 1979 Sale of Goods Act (SGA). It provides ways of terminating sale contracts in the two legal systems. There are ambiguous terms in the CISG and this article explains them. At the same time, this article emphasises the questions to which satisfactory answers have not yet been provided, and provides appropriate answers to them. In this article the writer undertook comparative analysis on the rules of avoidance of contract under the CISG and SGA. It ends with an appreciation of when a sale contract could be terminated under both laws. The comparative analysis revealed that the CISG discourages the avoidance of contracts and allows it only in the case of a fundamental breach. However, the SGA allows it only if a condition is breached.  It has also been revealed that the SGA seeks to gain certainty, but the CISG seeks to achieve justice in commercial transactions. However, a question remains: should certainty override justice? Key words: CISG, SGA, Fundamental Breach, Avoidance of Contract, Substantially Deprive

Identify and Analyze the Most Important Factors Affecting the Safety of Employees in Construction Sites in Iraq

تعد المشاريع الانشائية من أخطر الصناعات الانشائية من حيث تعرض سلامة وصحة العمال للحوادث المتنوعة والخطرة اثناء عملية البناء. إذ تبين احصائيات منظمة العمل الدولية وجود حادثة وفاة كل ثلاثة دقائق نتيجة إصابة العمال وان هنالك اربع إصابات مختلفة تحدث في العالم كل ثانية.  وقد تم تحديد صناعة البناء باعتبارها واحدة من الصناعات الأكثر خطورة، وذلك بسبب طبيعة العمل الناتج عن تكامل المواد والأدوات والبيئة والعوامل البشرية المختلفة حيث من الضروري إعطاء أهمية قصوى للسلامة المهنية والصحية للعمالة في مواقع المشاريع الانشائية وذلك لتقليل المخاطر والخسائر بين العمالة. حيث يعاني العراق من عدم الاهتمام بسلامة وصحة العمالة. ورغم أهمية السلامة والصحة للعاملين نلاحظ ان الأبحاث التي تطرقت لموضوع السلامة في المشاريع الانشائية تضل قليلة. يبدو أن الدراسات التجريبية حول تأثير الثقافة الوطنية على مواقف وسلوك وأداء السلامة قليلة. لا يبدو من غير المعقول أن نتوقع أن تختلف مواقف الناس تجاه المخاطر وفقًا للقيم والمعتقدات والافتراضات العميقة. لذا تم التركيز في هذا على اهم العوامل المؤثرة على سلامة وصحة العاملين في المواقع الانشائية وعمل اقتراحات حول من يتحمل هذه الإصابات صاحب العمل او المقاول ويتم ذكر كافة إجراءات السلامة اثناء كتابة عقد المقاولة ووضعها من الشروط الأساسية في المشروع.Construction sites are among the most dangerous construction industries in terms of exposing the safety and health of workers to various dangerous accidents during the construction process. Where the statistics of the International Labor Organization show that there is one death every three minutes as a result of a work injury and that there are four different injuries occurring in the world every second. The construction industry has been identified as one of the most dangerous industries, due to the nature of the work resulting from the integration of materials, tools, the environment and various human factors. A message of worker safety consideration during design sites. It is necessary to give the highest importance to the occupational and health safety of workers in construction projects sites in order to reduce risks and losses. Among worker. Iraq suffers from a lack of attention to safety and health of employment. Despite the importance of safety and health for workers, we note that research that deals with on the issue of safety in construction projects is still very little. Empirical studies on the effect of national culture on safety attitudes, behavior, and performance appear to be few. It does not seem unreasonable to expect people’s attitudes toward risk to differ according to the deep values, beliefs and assumptions that local culture influences safety in projects. Therefore, the focus was on the most important factors affecting the safety and health of workers in construction sites and making suggestions about who bears these injuries to the employer or contractor and all safety measures are mentioned while writing the contract and placing them as basic conditions in the project.                                                     &nbsp

Impact of a high-fat diet on dyslipidemia and gene expression of low-density lipoprotein receptors in male rats

Dyslipidemia is one of the leading causes of heart disease in human and pet animals. This study aimed to induce experimental dyslipidemia in adult male rats by a simple method via a high-fat diet. The 30 adult male rats were grouped as follows: The first group (G1) was feds a standard diet orally for five weeks as a control, while the second group (G2) was given a high-fat diet (dyslipidemia group) for five weeks. Serum lipid profile confirmed the induction, in which there were elevated cholesterol, triacylglycerol, very low-density lipoproteins, low-density lipoproteins, and depressed high-density lipoprotein, so, the atherogenic index in the dyslipidemic group was more significant than the control rat group. Low-density lipoprotein receptor plays an essential role in the metabolism of lipids in the blood. Thus, there was an upregulation (about seven folds) in the expression of genes of the receptor of low-density lipoprotein corresponding with the elevated receptor protein concentration (18.6 ng/ml) when compared with the control group (1.91 ng/ml). It could be concluded that experimental dyslipidemia could be induced in adult rats by consuming a high-fat diet within five weeks, and it is related to gene expression upregulation and protein elevation of a receptor of low-density lipoprotein, and this may be a compensatory mechanism to challenge hyperlipidemia

Laparoscopic Repair of Penetrating Injury of the Diaphragm: an Experience from a District Hospital

In this study we review our experience in using laparoscopy as a diagnostic and therapeutic tool in dealing with penetrating diaphragmatic injuries due to stab wounds and look at the feasibility of using this procedure in other similar institutions. Thirty patients, all of whom were males 20-30 years of age, presented to the surgical emergency unit of our hospital with upper abdominal and lower chest wall stab wounds between 01-05-1998 and 30-11-2006. Diagnosis of the diaphragm injury was either obvious with omentum herniating through the chest wall, or occult with confirmation of the injury at laparoscopy. All patients underwent diagnostic laparoscopy, which resulted in identification and efficient treatment of eight patients with diaphragmatic injury, and thereby laparotomy was avoided. The procedure converted to open surgery in one patient because of a small left-sided colonic tear. Laparoscopy is an efficient tool for the diagnosis and management of diaphragmatic injuries. It should be used routinely instead of exploratory laparotomy in haemodynamically stable patients with penetrating lower chest injuries

Contactless Heart Rate Detection Using MM-Wave Radar Systems Advancements

In recent years, there has been a significant surge in the development of non-contact methods for detecting heart and breathing rates. Various Millimeter-wave (MM-wave) radar systems, operating at different frequency bands like 10 GHz, 24 GHz, 77 GHz, and 122 GHz, have been effectively deployed for this purpose. This paper explores the vital application of contactless systems in the medical field, particularly during disasters and epidemics. These systems are crucial for detecting the heart and breathing rates of individuals trapped under debris, in military operations, long-term vital sign monitoring in hospitals, and aiding the elderly in public spaces. Consequently, our focus is on heart and breathing rate detection using radar systems. This paper highlights the significance of capturing the electrical representation of the heart signal. This approach is known for its trustworthiness and accuracy in identifying various medical conditions. Furthermore, a traditional method based on Fourier transform is presented for heart and respiration rate estimation. This method leverages the direct proportionality between heart and breathing rates and the frequencies of raw radar signals. To estimate the breathing rate, it identifies the maximum peak within the frequency range of 0.15 to 0.4 Hz in the frequency domain and multiplies the corresponding frequency by 60 to obtain the rate per minute. For heart rate estimation, it detects the maximum peak within the frequency range of 0.8 to 2 Hz and calculates the rate per minute accordingly

Pixel steganography method for grayscale image steganography on colour images

The process of hiding secret data within a host signal is known as steganography; its design parameters are imperceptibility, concealment capacity, and recovered data quality. A case of images, one of the existing methods based on modification of the host image pixels is called Block Pixel Hiding Method (BPHM), which has good imperceptibility and high-capacity concealment but does not guarantee the quality of the secret image recovered. This article proposes a method that improves results BPHM based on band selection and search algorithm global called Improved Pixel Hiding Method (IPHM). According to the simulations carried out, the results obtained with IPHM are better than those obtained with BPHM. They are similar to one of the more popular methods in imaging steganography known as Quantization Index Modulation (QIM). Steganography is the method of hiding hidden data within a host signal, with imperceptibility, concealment capacity, and retrieved data quality as design criteria. In the case of images, Block Pixel Hiding Method (BPHM) is one of the available methods based on modifying the host picture pixels, which has good imperceptibility and high-capacity concealment but does not guarantee the quality of the hidden picture recovered. Improved Pixel Hiding Method is a method proposed in this article that improves BPHM outcomes by using band selection and a global search algorithm (IPHM). The results obtained using IPHM are better than those achieved with BPHM, according to simulations. They're related to Quantization Index Modulation, which is one of the most widely used picture steganography techniques (QIM)

Empirical analysis of rough set categorical clustering techniques based on rough purity and value set

Clustering a set of objects into homogeneous groups is a fundamental operation in data mining. Recently, attention has been put on categorical data clustering, where data objects are made up of non-numerical attributes. The implementation of several existing categorical clustering techniques is challenging as some are unable to handle uncertainty and others have stability issues. In the process of dealing with categorical data and handling uncertainty, the rough set theory has become well-established mechanism in a wide variety of applications including databases. The recent techniques such as Information-Theoretic Dependency Roughness (ITDR), Maximum Dependency Attribute (MDA) and Maximum Significance Attribute (MSA) outperformed their predecessor approaches like Bi-Clustering (BC), Total Roughness (TR), Min-Min Roughness (MMR), and standard-deviation roughness (SDR). This work explores the limitations and issues of ITDR, MDA and MSA techniques on data sets where these techniques fails to select or faces difficulty in selecting their best clustering attribute. Accordingly, two alternative techniques named Rough Purity Approach (RPA) and Maximum Value Attribute (MVA) are proposed. The novelty of both proposed approaches is that, the RPA presents a new uncertainty definition based on purity of rough relational data base whereas, the MVA unlike other rough set theory techniques uses the domain knowledge such as value set combined with number of clusters (NoC). To show the significance, mathematical and theoretical basis for proposed approaches, several propositions are illustrated. Moreover, the recent rough categorical techniques like MDA, MSA, ITDR and classical clustering technique like simple K-mean are used for comparison and the results are presented in tabular and graphical forms. For experiments, data sets from previously utilized research cases, a real supply base management (SBM) data set and UCI repository are utilized. The results reveal significant improvement by proposed techniques for categorical clustering in terms of purity (21%), entropy (9%), accuracy (16%), rough accuracy (11%), iterations (99%) and time (93%). vi
