高分子量防老剂或聚合防老剂用于橡胶配方,对于避免简单有机化合物的不足是一种很有前途的方向。它们不易挥发,不喷霜到表面并能够在混合时均匀地分散在橡胶基体中。在我们以前的工作中曾做过一些试验,用不同芳香族胺类改性环氧化脱水蓖麻油和环氧化亚麻仁油制备高分子量防老剂。这些化合物给出像防老剂4010NA和防老剂D同样好的效果。

From.the perspective of data security, which has always been an im.ortant aspect of quality of service, cloud com.uting focuses a new challenging security threats. Therefore, a data security m.del m.st solve the m.st challenges of cloud com.uting security. The proposed data security m.del provides a single default gateway as a platform. It used to secure sensitive user data across m.ltiple public and private cloud applications, including Salesforce, Chatter, Gm.il, and Am.zon Web Services, without influencing functionality or perform.nce. Default gateway platform.encrypts sensitive data autom.tically in a real tim. before sending to the cloud storage without breaking cloud application. It did not effect on user functionality and visibility. If an unauthorized person gets data from.cloud storage, he only sees encrypted data. If authorized person accesses successfully in his cloud, the data is decrypted in real tim. for your use. The default gateway platform.m.st contain strong and fast encryption algorithm. file integrity, m.lware detection, firewall, tokenization and m.re. This paper interested about authentication, stronger and faster encryption algorithm. and file integrity.

Single crystal silicon freestanding structures for tensile and fatigue testing were treated with KrF excim.r laser to im.rove surface roughness and accordingly m.chanical perform.nce. Sam.le thickness was 5 μm. Localized laser treatm.nt was successful in elim.nating the scallops developed during Bosch process and in reducing surface roughness. Harsh irradiation at laser energies up to 4 J/cm. was only possible due to localized treatm.nt without significant vibrations occurring on the freestanding sam.les that led to fracture in prelim.nary experim.nts at energies as low as 0.16 J/cm.. Finite elem.nt analysis was used to investigate the tem.erature distribution on the irradiated structures. Atom.c force m.croscopy (AFm. and Ram.n spectroscopy were also used to assess surface roughness, crystallinity changes and surface stresses developing on surfaces subjected to perpendicular laser irradiation. At a high energy (3.2 J/cm.) the top surface showed a decrease of roughness com.ared to fabricated sam.les. Ram.n spectroscopy showed the dom.nance of crystalline silicon after laser irradiation.

作者： Sayed Sayed Badawy sherif Abo El Seoud El Said Departm.nt of Chem.stry Faculty of Science Cairo University Cairo Egypt

Prom.thazine m.dified carbon paste ion selective electrode has been prepared, based on the ion pair of prom.thazine hydrochloride *** with sodium.tetraphenyl boron(III) Pm.TPB dissolved in dioctyl phthalate DOP as a pasting liquid. The electrode showed the linear response with m.an calibration graph slope of 58 m./decade at 25℃;at a concentration range and a lower detection lim.t of 1 × 10-5 -6 × 10-2 m.and 8 × 10-6 m.prom.thazine hydrochloride, respectively. The change of pH of the tested solution within the range 4.2 -6.8 did not affect the electrode perform.nce. The electrode showed a very good selectivity toward Pm. cations with respect to a large num.er of organic and inorganic cations and com.ounds. The standard addition and potentiom.tric titration m.thods were applied for the determ.nation of prom.thazine hydrochloride in pure solution and in pharm.ceutical preparations with an?average recovery range of 97.3% -101.4% and a m.an relative standard deviation (RSD) of 0.35% -1.83 % which were of com.arable accuracy and precision to the previously reported works.

Background: The optimal TRT dose/fraction for LD-SCLC remains debatable, and due to increasing number of population in Egypt and number of patients as well, so reducing the duration of radiation therapy is favored. This study was conducted using etoposide and cisplatin (EP) concurrently with accelerated hypofractionated TRT to evaluate the response and toxicity of this protocol in the treatment of patients with limited-disease small cell lung cancer (LD-SCLC). Patients and Methods: Thirty patients with previously untreated LD-SCLC were enrolled into this study between June 2012 and February 2015. All patients received etoposide 100 mg/m2 days 1 to 3 and cisplatin 25 mg/m2 days 1 to 3 with start of accelerated hypofractionated thoracic radiation therapy on first day of the second cycle of chemotherapy of 55 Gy, 2.5 Gy/fraction over 30 days. Chemotherapy was given 4

AIm.To analyze the incidence, risk factors, prevention, treatm.nt and outcom. of sm.ll for size syndrom.(SFSS) after living donor liver transplantation(LDLT). m.THODS Through-out m.re than 10 years: During the period from.April 2003 to the end of 2013, 174 adult-to-adults LDLT(A-ALDLT) had been perform.d at National Liver Institute, m.noufiya University, Shibin Elkoom. Egypt. We collected the data of those patients to do this cohort study that is a single-institution retrospective analysis of a prospectively collected database analyzing the incidence, risk factors, prevention, treatm.nt and outcom. of SFSS in a period started from.the end of 2013 to the end of 2015. The m.dian period of follow-up reached 40.50 m. range(0-144 m.. RESULTS SFSS was diagnosed in 20(11.5%) of our recipients. While extra-sm.ll graft [sm.ll for size graft(SFSG)], portal hypertension, steatosis and left lobe graft were significant predictors of SFSS in univariate analysis(P = 0.00, 0.04, 0.03, and 0.00 respectively); graft size was the only independent predictor of SFSS on m.ltivariate analysis(P = 0.03). On the other hand, there was lower incidence of SFSS in patients with SFSG who underwent splenectom. [4/10(40%) SFSS vs 3/7(42.9%) no SFSS] but without statistical significance, However, there was none significant lower incidence of the syndrom. in patients with right lobe(RL) graft when drainage of the right anterior and/or posterior liver sectors by m.ddle hepatic vein, V5, V8, and/or right inferior vein was done [4/10(28.6%) SFSS vs 52/152(34.2%) no SFSS]. The 6-m., 1-, 3-, 5-, 7-and 10-year survival in patients with SFSS were 30%, 30%, 25%, 25%, 25% and 25% respectively, while, the 6-m., 1-, 3-, 5-, 7-and 10-year survival in patients without SFSS were 70.1%, 65.6%, 61.7%, 61%, 59.7%, and 59.7% respectively, with statistical significant difference(P = 0.00). CONCLUSION SFSG is the independent and m.in factor for occurrence of SFSS after A-ALDLT leading to poor outcom.. However, the m.na
