The sachun Formation in the Zagros Mountains Ranges was sampled on the basis of changes in lithology and 150 vertically oriented thin-sections were prepared and subjected to detailed petrographic study. Evaporite, carbonate and shale/marl facies are identified here. These facies which have been laid in 4 facies belts of supratidal, intertidal, lagoon and barrier, deposited on a ramp platform. Petrographic studies showed that the sachun Formation has had a complex diagenetic history. The following diagenetic events occurred in the carbonate microfacies： micritization, dissolution, silicification, dolomitization, hematitization, compaction, fracturing and stylolitization. The diagenetic features observed petrographically in the carbonate microfacies represent changes which took place under three diagenetic environments（eogenic, mesogenic, and telogenic） with three different marine, burial, and meteoric diagenetic conditions. The diagenetic sequence of events that affected the sachun Formation includes micritization and micrite envelope features which have been reported from an eogenic/marine environment.

Nine distinct zinc-nickel-tin films with different compositions have been galvanostatically electrodeposited. The films have been characterized by scanning electron microscopy(sEM) and energy dispersive spectrometry(EDs). Their corrosion potentials and densities have been estimated using Tafel extrapolation. Next, the electrochemical behaviors of the films(deposited through the electrolytes containing 0, 6, 8, and10 g/L snCl2?6H2O) have been examined based on cyclic voltammetry(CV) measurements. Further, these films have been immersed in 3.5 wt%Na Cl solution for 1 h, 1 d, 7 d, 14 d, 28 d, and 42 d followed by application of Tafel extrapolation and electrochemical impedance spectroscopy(EIs) tests on each aged sample. Finally, to analyze the morphologies and the compositions of the oxide films covering the surfaces of the 42-d aged films, FT-IR and sEM analyses have been performed. The results indicated that the Zn–Ni–sn film produced through the bath including 6g/L snCl2?6H2 O exhibits superior corrosion resistance because of the high Ni content in the presence of sn that promotes the barrier protection capability of the deposit.

Post-dural puncture headache （PDPH）, recognized as one of the most frequently observed complications of spinal anesthesia, occurs due to cerebrospinal fluid （CsF） leakage from a defect in the dura mater formed because of a trauma. Generally, the pain is bilateral frontal, retroorbital, or occipital, which radiates toward the neck. Most characteristic feature of PDPH is its postural nature. It aggravates by sitting or standing, whereas it declines or it is completely resolved by lying down. Generally, PDPH occurs within the 72 h after the procedure, and if it＇s untreated, it may last for several weeks.（1）

The on-chip memory performance of embedded systems directly affects the system designers＇ decision about how to allocate expensive silicon area. A novel memory architecture, flexible sequential and random access memory （FsRAM）, is investigated for embedded systems. To realize sequential accesses, small “links”are added to each row in the RAM array to point to the next row to be prefetched. The potential cache pollution is ameliorated by a small sequential access buyer （sAB）. To evaluate the architecture-level performance of FsRAM, we ran the Mediabench benchmark programs on a modified version of the simplescalar simulator. Our results show that the FsRAM improves the performance of a baseline processor with a 16KB data cache up to 55%, with an average of 9%; furthermore, the FsRAM reduces 53.1% of the data cache miss count on average due to its prefetching effect. We also designed RTL and sPICE models of the FsRAM, which show that the FsRAM significantly improves memory access time, while reducing power consumption, with negligible area overhead.
