    Abstract: In this paper, enhancing the energy absorption by using slurry infiltrated fibrous concrete (SIFCON) in flat slab-column connection is studied. Eight specimens of reinforced concrete slabs identical in reinforcement and dimensions were tested, six of them were casted as a hybrid reinforced concrete slabs [normal strength concrete (N.S.C) and SIFCON] and the remaining two slabs were casted with a N.S.C as control specimens. SIFCON was casted monolithically with a N.S.C with a different thickness by a square shape of side length (0.5 d) at the center of the specimens, once at all the thickness of cross section of the slab (80 mm) and the others at half thickness (40 mm) either at compression or tension face of the slabs. Two types of fiber were used in SIFCON. All specimens were tested under the same condition by applied a vertical load downward through a square column with dimensions of (100*100*200 mm). The results showed that the use of SIFCON increasing the energy absorption for all cases with a varying percentage according to the location of casting SIFCON within the cross section of the slabs and the type of fibers which used in SIFCON. The enhancement in energy absorption due to using SIFCON with a square shape at center of slabs (155 mm) was ranged from 36.04% to 77.37% compared with the control specimens.

    Abstract: This paper examined the comparison between the mechanical properties of mortar infiltrated fibers concrete with two types of fibers (End hooked steel fiber and Synthetic fiber) with varying fibre volume. The difference in properties of the concrete with steel fiber, concrete without fiber and concrete with Synthetic fiber was determined. Compressive strength and flexural strength (Modulus of rupture) of concrete were determined. The concrete mixing containing [0% control, (2,4 and 6%)] fibre volume of (End Hooked) and Synth etic fiber were used for compressive and flexural strengths tests. Steel fiber was (30 mm) in length and (0.5mm) diameter, while Synthetic fiber was (60mm) in length and (0.84mm) diameter. the concrete cube used was (100×100mm) for compressive strength test, also beam used for flexural strength test with dimensions (400×100×100mm). The results showed that with increasing volumetric ratio of fiber, the compressive strength and flexural strength increase. The compressive strength and flexural strength of hooked fiber have a much higher extent increasing than that of synthetic fiber.

    Abstract: This search aims to study and test the effect of using a new material (mortar infiltrated fiber concrete) as repair material in crucial regions that need a special type of repair like (deck of bridges, pavements, and defense structures). This work consisted of three stages: the first stage; testing the engineering properties of slurry infiltrated fiber concrete (compressive, splitting tensile, flexural and bond strengths), by using different types of fibers (End hooked steel fiber, Micro steel fiber, Polypropylene fiber, and Synthetic fiber), in five different types of mortar infiltrated fiber concrete mixes (with a volumetric ratio of fiber 6%), and the age of test was 28 days. After studying the behavior of these mixes in these tests, the second stage of this study was concluded casting reference slab with dimensions 900×900×80 mm from normal strength concrete and repairing two sets of damaged slabs (with dimensions 900×900×50 mm, the first set consist of five slabs damaged in the compression zone, and the second set consist of five slabs damaged in tension zone), the two sets repaired with repair layer from mortar infiltrated fiber concrete with thickness 30 mm. The third stage of the study was testing the effect of the repair material (mortar infiltrated fiber concrete) on the flexural behavior of the repaired slab specimens in (flexural strength, deflection characteristics, and ductility), through using a hydraulic jack with a four-point load system. The results of testing slab specimens indicated significant improvement in the flexural behavior of the repaired slab when compared with the reference slab, the slabs repaired in the compression zone recorded increasing in range 2-39% in ultimate load and the slabs that repaired in tension zone recorded 4-71% increasing in ultimate load .also recorded better deflection values through testing the slabs specimens that repaired. The ductility of the repaired slab specimens increased significantly from 25 to 91% compared with the reference slab specimens. These results indicated excellent effect mortar infiltrated fiber concrete as a perfect repair material for slabs that damaged in compression and tension zones.

    Abstract: Pseudo‐pacemaker syndrome (PPMS) is a rare complication of first‐degree atrio‐ventricular (AV) block in which a very prolonged PR interval causes AV dyssynchrony and subsequent symptoms of hemodynamic instability in the absence of an implanted pacemaker. The aim of this manuscript was to describe a unique case of PPMS and to provide a comprehensive review of the topic to help clinicians in the diagnosis and management of this condition. Through systematic research on PubMed, Google Scholar, EBSCO, and Ovid MEDLINE and using the search strings “pseudo‐pacemaker syndrome” and “symptomatic first‐degree AV block,” we identified 14 articles accounting for 17 cases of PPMS, including our case report. The most common age group for PPMS was middle‐aged and young adults, with an average age of 47 years. Palpitations were the most common presenting symptom and four main etiologies of PPMS were identified, as follows: (1) Idiopathic PPMS with evidence of impaired conduction over the AV node (20% of cases), (2) PPMS associated with reversable inflammatory causes (13%) or (3) associated with iatrogenic surgical or interventional procedures leading to the permanent damage of the normal AV conduction system (20%), and, finally, (4) PPM related to dual AV nodal physiology (DAVNP) as a primary finding (27%) or occurring after fast or slow pathway ablation for treatment of AV nodal re‐entrant tachycardia (AVNRT) (20%). Treatment should be patient‐tailored and based on the specific etiology once identified. However, the treatment of PPMS due to DAVNP without AVNRT presentation is yet to be clarified.

    Abstract: Tin disulfide (SnS 2 ) thin films have drawn worldwide attention because of their outstanding performance and earth-abundant constituents. However, problems such as coexistence of complex secondary phases (SnS, Sn 2 S 3 ), the band tailing issue, and bulk defects need to be addressed for further efficiency improvement. In this regard, the present work is intended for the treatment of one of these problems. Herein, a single phase SnS 2 has been obtained using an ultrasonic spray pyrolysis method. which is confirmed by X-ray diffraction (XRD) and energy dispersive X-rays (EDXs) characterization techniques. The substrate temperatures (Ts) were increased from 250 °C to 450 °C, and this significantly improved the film's characteristics, which varied from an amorphous phase and a mixture of crystalline phases, SnS 2 and SnS (for the films obtained at Ts = 250 and 300 °C) to a SnS 2 pure phase with a hexagonal structure (for Ts ≥ 350 °C). The morphological, optical, and electrical properties of SnS 2 films are greatly improved by temperature increases too, especially for the film obtained at 450 °C. This suggests that there are opportunities for further efficiency by using the as-deposited SnS 2 thin film at 450 °C.

    Cryogenic Memory Architecture Integrating Spin Hall Effect based Magnetic Memory and Superconductive Cryotron Devices

    Abstract: One of the most challenging obstacles to realizing exascale computing is minimizing the energy consumption of L2 cache, main memory, and interconnects to that memory. For promising cryogenic computing schemes utilizing Josephson junction superconducting logic, this obstacle is exacerbated by the cryogenic system requirements that expose the technology’s lack of high-density, high-speed and power-efficient memory. Here we demonstrate an array of cryogenic memory cells consisting of a non-volatile three-terminal magnetic tunnel junction element driven by the spin Hall effect, combined with a superconducting heater-cryotron bit-select element. The write energy of these memory elements is roughly 8 pJ with a bit-select element, designed to achieve a minimum overhead power consumption of about 30%. Individual magnetic memory cells measured at 4 K show reliable switching with write error rates below 10 −6 , and a 4 × 4 array can be fully addressed with bit select error rates of 10 −6 . This demonstration is a first step towards a full cryogenic memory architecture targeting energy and performance specifications appropriate for applications in superconducting high performance and quantum computing control systems, which require significant memory resources operating at 4 K.
