he Cuckoo of Faith is one of the curses who have given the Shari'a and consequently the law and the foundation of the rationale for the customer. In the event of a product being defective, the customer will be in a position to terminate the contract and / or to obtain an order and sign the contract. By contrast, any verb and manipulation that, in the common sense of the people, imply the abandonment of obligations and obligations, will deprive them of the right to reject and commit to a transaction. One of the things that causes the right to decline is to seize it in such a way as to cause the same change. This change should be in such a way that the other is not the same as the original condition that was traded. The common sense of the mind ignores the slight changes, and any loss of the attribute of health or the adjective of perfection also accompanies the change at the same time and causes the fall of the right to reject. On the other hand, if a number of transactions are made on this basis, the customer can return the goods and cancel the transaction and cancel the transaction until it has remained in its original condition and has the possibility and ability to return to the bank. To restore.

Two experiments investigated the False memory effect (the Deese - Roediger - McDermott paradigm) among the Iranian population. In experiment 1, subjects studied list of semantically associated words. In experiment 2 which was an extension of the afore - mentioned paradigm, lists of linedrawings of semantically associated words were presented. In both experiments, a high rate of False recall and False recognition was observed. The findings suggest that a) - the effect is replicable among the Iranian population and b) - it can be generalized to pictorial stimuli. The results are discussed in terms of the network theories.

This paper reviews the factors that have led to delays in gas company projects in East Azerbaijan. The study uses questionnaires to collect information from 76 key respondents including senior and middle managers, contractors and monitoring officers linked with the gas company of East Azerbaijan Province. We use Kolmogorov-Smirnov one-sample to test data normality, the t test to investigate the 13 different hypotheses initially formulated and the Friedman test to prioritize amongst them. The following factors are shown to account for the delays experienced: 1) insufficient allowance for rising costs 2) lack of timely supply of funds 3) lack of strong employer support and effective delineation of lines of authority for dealing with problems 4) lack of timely issuance of drilling permits 5) delays in delivery of goods 6) The physical conditions of project sites 7) local cultural conditions and 8) risk management.

Today, advertisement is an important part of all businesses. the use of False information in these advertisements is always targeting consumers and rival traders. No doubt in these circumstances consumers need to be protected, however, it is not clear what kind of support and protection can be afforded for consumers and how they can be compensated? Can they terminate the contract, or they have to keep the goods and claim for compensation due to civil liability of the supplier? On the other hand, it is not clear what the liability of the media for propagating False advertisements is and how consumers can make claims against the producer of False advertisement and what compensations are available to the consumers from them? False advertisements may also be used against rival businesses as competing traders and make them lose their market. Here also the question is whether the rival trader has the right to claim compensation from people benefiting from the False advertisement for their losses.

Aim: In this study we tried to find out the accuracy of biliary tract brushing cytology in our center as the largest referral center in the south of Iran. Background: Common bile duct brushing cytology has been introduced as the method of choice for the diagnosis of pancreaticobiliary malignancies. However, there have been controversial reports about the sensitivity, specificity and overall accuracy of this method in the English literature. Methods: During the study period (2012-2016) there has been 166 cases of common bile duct brushing cytology taken during endoscopic retrograde cholangiopancreatography (ERCP). One case has been excluded because of inadequate number of cells in the cytology smear. All the smears have been stained by routine cytologic stains and screened by cytotechnologists and diagnosed by expert cytopathologist. Final diagnosis by biopsy has been considered as the gold standard. Results: According to the final histologic diagnosis as the gold standard, there were 22 False negative and 7 False positive cases. All of the False positive cases have been suspected cases in the background of primary sclerosing cholangitis. The most common final diagnosis of False negative cytologic diagnoses has been intrahepatic cholangiocarcinoma in which no malignant cell has been identified in the presence of adequate number of normal ductal epithelial cells. Conclusion: Common bile duct brushing cytology is the method of choice for the diagnosis of pancreaticobiliary tract malignancies; however, having high specificity (90%), the sensitivity is low (56%). Cytologic diagnosis of biliary tract malignancies should be made with caution in the patients with primary sclerosing cholangitis. Also it is important to know that high False negative rate is present in common bile duct brushing cytology especially in the cases of intrahepatic cholangiocarcinoma without extension into extrahepatic ducts.

The Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) has spread rapidly and developed the current pandemic and the stressful lifestyle in addition with extreme pressure on people was the consequence of its increasing mortality rate. Since COVID-19 is highly infectious, it is crucial to diagnose the disease timely and initiate preventive measures to control the epidemic. Therefore, the need for accurate detection of this virus has been increased dramatically. Real-Time reverse-transcription Polymerase Chain Reaction (RTPCR) tests are considered a gold standard to detect SARS-CoV-2 RNA. Besides, the recent pandemic has posed the most serious challenge in PCR applications to date. Although RT-PCR has great accuracy, some factors can reduce the efficiency of this test. Time of testing and type of sample are typical elements that may cause False negative results. Furthermore, False positive cases would be the result of contamination and unoptimized primers. In this paper, the relevant factors creating False positive and False negative results have been investigated in depth to increase the awareness of clinicians.

Aspirin (acetylsalicylic acid; ASA) is one of the most commonly used drugs, Studies have showed that low dose ASA can reduce cardiovascular events by irreversibly binding to cyclooxygenase and inhibiting platelet aggregation. However, ASA has not prevented all patients from cardiovascular events [1]. Ackerman and Newman were the first to describe the phenomenon of Aspirin resistance (AR) in 1990, named "incomplete antiplatelet effect of aspirin". Afterwards, in the last two decades, several studies have demonstrated that some people do not respond to low dose aspirin as an anti-platelet [2].
