The transparency-reflection in puns arabic translation

The term transparency in the translation of puns in the holy Quran plays an important role in reflecting the text-originality. Its significance lies in the fact that puns have certain sound effects and aesthetic features that should be reflected in the translation process. Failure to reflect these features may lead to a less transparent product. A main problem that may face translators is to find the suitable vocabulary in the target language that can reflect both the intended meaning and the pun’s unique characteristics. In order to deal with this problem, translators make sure to produce a text that has a high degree of transparency. It enables the original texts to shine through translation as it keeps the foreignness of the source text maintained

Bond strength of a new Kevlar fiber-reinforced composite post with semi-interpenetrating polymer network (IPN) matrix

This study aimed to evaluate the bond strength and the penetration depth of two adhesive systems to a new experimental semi-IPN fiber post versus a commercial post. Experimental Kevlar fiber (KF) and control everStick®POST (ES) posts (n=20/ group) with a diameter of 1.5 mm were used, 10 posts coated with StickResin (SR) and the other 10 posts coated with Scotch bond multipurpose (SBMP) adhesives. Composite resin buildup was performed over each post, using a cylindrical plastic mold (10 mm × 6 mm). Four discs of 2 mm thickness were prepared from each post/composite buildup and underwent pushout bond strength test at a crosshead speed of 0.5 mm/min accompanied by failure mode analysis. A further three specimens from each subgroup were bonded with adhesives labeled with 0.1 wt% Rhodamine B and embedded in acrylic resin, sectioned and examined under a confocal Laser-scanning microscope (CLSM) to measure the depth of resin penetration. Statistical analysis included ANOVA and Tukey test, the significance level was assumed at a p-value less than 0.05. The push-out bond strength of KF was comparable to that of ES with both SBMP and SR adhesives (P >0.05). Bond strength value for SBMP was higher than SR adhesive in either ES and KF posts with no significant difference (P > 0.05). ES exhibited higher adhesive penetration depth compared with KF (p<0.05). The bond strength of Kevlar post was comparable with the everStick post and the semi-interpenetrating structure of Kevlar post displayed some adhesive monomers diffusion indicating its usefulness as a new intracanal post

A malignant omental extra-gastrointestinal stromal tumor on a young man: a case report and review of the literature

<p>Abstract</p> <p>Background</p> <p>Gastrointestinal stromal tumors (GIST) are uncommon intra-abdominal tumors. These tumors tend to present with higher frequency in the stomach and small bowel. In fewer than 5% of cases, they originate primarily from the mesentery, omentum, or peritoneum. Furthermore, these extra-gastrointestinal tumors (EGIST) tend to be more common in patients greater than 50 years of age. Rarely do EGIST tumors present in those younger than 40 years of age.</p> <p>Case presentation</p> <p>We report a case of a large EGIST in a 27-year-old male. An abdominal pelvic computerized tomography imaging demonstrated an intra-abdominal mass of 22 cm, without invasion of adjacent viscera or liver lesions. This mass was resected <it>en bloc </it>with its fused omentum and an adherent portion of sigmoid colon. Pathology results demonstrated a malignant gastrointestinal stromal tumor with positive CD117 (c-kit) staining, and negative margins of resection, and no continuity of tumor with the sigmoid colon. Due to the malignant and aggressive nature of this patient's tumor, he was started on STI-571 as adjuvant chemotherapy.</p> <p>Conclusion</p> <p>Stromal tumors of an extra-gastrointestinal origin are rare. Of the reported omental and mesenteric EGISTs in four published series, a total of 99 tumors were studied. Of the 99 patients in these series only 8 were under 40 years of age, none were younger than 30 years old; and only 5 were younger than 35 years old. Our patient's age is at the lower end of the age spectrum for the reported EGISTs. Young patients who present with an extra-gastrointestinal stromal tumor (EGIST), who have complete resection with negative margins, have a good prognosis. There is little data to support the role of STI-571 in adjuvant or neoadjuvant therapy after curative resection. Given the lack of data, the use of STI-571 must be individualized.</p

Recent approaches in designing bioadhesive materials inspired by mussel adhesive protein

Marine mussels secret protein-based adhesives, which enable them to anchor to various surfaces in a saline, intertidal zone. Mussel foot proteins (Mfps) contain a large abundance of a unique, catecholic amino acid, Dopa, in their protein sequences. Catechol offers robust and durable adhe-sion to various substrate surfaces and contributes to the curing of the adhesive plaques. In this article, we review the unique features and the key functionalities of Mfps, catechol chemistry, and strategies for preparing catechol-functionalized poly- mers. Specifically, we reviewed recent findings on the contributions of various features of Mfps on interfacial binding, which include coacervate formation, surface drying properties, control of the oxidation state of catechol, among other features. We also summarized recent developments in designing advanced biomimetic materials including coacervate-forming adhesives, mechanically improved nano- and micro-composite adhesive hydrogels, as well as smart and self-healing materials. Finally, we review the applications of catechol-functionalized materials for the use as biomedical adhesives, therapeutic applications, and antifouling coatings

Programming SnO2 gas Sensor using Arduino microcontroller

Most of the gases are dangerous or bad for human being and environment. Proper attention should be taken while using or transporting these gases. In the present work, these gases will be detected according to the acceptable limits. The Arduino microcontroller attached to a personal computer will be used to detect several gases such as hydrogen, butane, humidity, etc. The sensitive gas is tin dioxide (SnO2) that is fabricated as a unit called MQ-2, MQ-3, and MQ-135 …etc, or other sensors. As the sensors are exposed to a particular gas, a signal is transmitted to the Arduino microcontroller and attached to the personal computer. This signal is processed and calibrated using C language programming to indicate the concentration of the gas. These sensors are necessary for safety and environmental monitoring of the gases mentioned above such as monitoring butane transportation and household usages. The monitored gas data can be shared with other Internet sites or the cloud that can act as a response to the values of gas concentration by giving sounds or turn lights on or other alarm responses. The alarm sounds, and a fan simultaneously can be operated to remove the excess gas and to reduce its concentration to the acceptable levels. The Arduino microcontroller can be operated without the need of a computer after loading the required program. The operation of the Arduino without a computer greatly reduces the cost of installation of a gas sensor. Transmitting of sensor data can be performed by using programs such as Teamviewer if the microcontroller is attached to a computer. Transmitting data can also be performed without a computer by using ESP8266 that can communicate directly to the Internet. The sensor calibration can be done using a linear fitting or exponential fitting. The use of the exponentials fitting is the ultimate accurate method because of the natural shape behavior of the gas sensing curves
