Let H be a subgroup of a finite group G. We say that H is SS-semipermutable in Gif H has a supplement K in G such that H permutes with every Sylow subgroup X of Kwith (jXj; jHj) = 1. In this paper, the Structure of SS-semipermutable subgroups, and finitegroups in which SS-semipermutability is a transitive relation are described. It is shown thata finite solvable group G is a PST-group if and on...

The synthesis of polyaniline doped with dodecylbenzene sulphonic acid (Pani-DBSA) coatings on 310 stainless steel (310 SS) surfaces has been investigated by using the galvanostatic method. The synthesized coatings were characterized by Fourier Transform Infrared Spectroscopy (FT-IR), UV-Visible absorption spectrometry and Scanning Electron Microscopy (SEM...

The preparation of polyaniline/zeolite nanocomposite coating on 304 stainless steel (304 SS) surface has studied via the galvanostatic method. The electro-generated coating was characterized by Fourier transform infrared spectroscopy (FT-IR), UV-visible absorption spectroscopy, X-ray diffraction (XRD) patterns and scanning electron microscopy (SEM). The anticorrosion property of polyaniline/zeo...

Sirs, In the US/European Consensus Group (EUCG) classification criteria for Sjögren’s syndrome (SS) objective items, such as focal sialadenitis and serum presence of antiSS-A and anti-SS-B antibodies (anti-SS-A, anti-SS-B), are emphasized (1). In the sera of approximately 20% of SS patients no anti-SS-A or anti-SS-B can be detected at the time of diagnosis. However, in these ‘seronegative’ pati...

پیوند اعضا از ارکان مهم سیستم‌‌های سلامت است و به درمان بسیاری بیماری‌‌های صعب‌العلاج کمک شایانی کرده است. روزانه 7 تا 10 نفر بیماران نیازمند در ایران علت نرسیدن به‌موقع عضو پیوندی دنیا می‌­روند. با توجه بحرانی­‌بودن زنجیره برای سلامتی انسان، مدیریت برنامه‌ریزی این اهمیت فراوانی برخوردار انتقال بیمار یک بیمارستان محل تأثیر ثانیه‌‌ها بر کیفیت مورد­انتقال موفقیت پیوند، بسیار حائز پژوهش، مدلی ریاض...

A new component of the complement (C).system, with a specific binding affinity for the activated Ss-protein (C4) has been identified in mouse serum. This protein, named Ss- (or C4)-binding protein (Ss-bp), was purified about 200 times from mouse plasma. Ss-bp is a heat stable (56 degrees C, 60 rain) beta-globulin with a sedimentation coefficient in sucrose density ultracentrifugation of 10s. It...
