Magnetic Field and Permeability Effects on Jeffrey Fluid in Eccentric Tubes Having Flexible Porous Boundaries

Arshad Riaz,Abdul Razaq,Aziz Ullah Awan 한국자기학회 2017 Journal of Magnetics Vol.22 No.4

In the present study, we recapitulated the magnetic field and porous medium effects on the peristaltic mechanism of a Jeffrey fluid model observed between two electrically conducting eccentric annuli. The inner annulus is assumed to be rigid and to contain constant velocity across the longitudinal direction of the enclosure; the outer one is considered to be flexible and to experience peristaltic waves travelling down its walls. Moreover, the magnetic field is examined in the direction normal to the pattern in the presence of a porous medium. The flow, meanwhile, is incompressible and follows in an unsteady format. The flow’s descriptive equations are reduced by anticipation of long wave length and small Reynolds number approximations. The resulting governing equations are then handled using analytical techniques. The achieved expressions for the considerable functions are manipulated graphically to determine the influences of various appertaining parameters. Finally, the results are compared with those of previous studies to confirm the validity of the present solutions through tables and graphs. The graphs indicated that the magnetic field increases the pumping rate but that the porosity reduces it.

Curing agents are critical components of aqueous epoxy resin systems. Unfortunately, its uses and applications are restricted because of its low emulsifying yields. Epoxy resins are frequently used in electrical devices, castings, packaging, adhesive, corrosion resistance, and dip coating. In the presence of curing agents, epoxy resins become rigid and infusible. Eco-friendliness and mechanical functionality have emerged as vulcanization properties. Curing agents are used for surface modification, thermodynamic properties, functional approaches to therapeutic procedures, and recent advances in a variety of fields such as commercial and industrial levels. The curing agent has superior construction and mechanical properties when compared to the commercial one, which suggests that it has the potential for use as the architectural and industrial coatings. The thermal stability of cured products is good due to the presence of the imide group and the hydrogenated phenanthrene ring structure. Over the course of the projection period, it is anticipated that the global market for curing agents will continue to expand at a steady rate. The growth of the market is mainly driven by its expanding range in future applications such as adhesives, composites, construction, electrical, electronics, and wind energy. This review focused on the most recent advancements in curing techniques, emphasizing their thermal and mechanical properties. The review also presents a critical discussion of key aspects and bottleneck or research gap of the application of curing agents in the industrial areas.

Cryptographic hash functions are widely used in many information security applications like digital signatures, message authentication codes (MACs), and other forms of authentication. In response to recent advances in cryptanalysis of commonly used hash algorithms, National Institute of Standards and Technology (NIST) announced a publicly open competition for selection of new standard Secure Hash Algorithm called SHA-3. One important aspect of this competition is evaluation of hardware performances of the candidates. In this work we present efficient hardware implementations of SHA-3 finalists: JH, Keccak and Skein. We propose high speed architectures using Look-Up Table (LUT) resources on FPGAs, to minimize chip area and to reduce critical path lengths. This approach allows us to design data paths of SHA-3 finalists with minimum resources and higher clock frequencies. We implemented and investigated the performance of these candidates on modern and latest FPGA devices from Xilinx. This work serves as performance investigation of leading SHA-3 finalists on most up-to-date FPGAs.

PHA-Induced Peripheral Blood Cytogenetics and Molecular Anslysis : a Valid Diagnostic and Follow-up Modality For Acute Primyelocytic Leukemia Patients Treated With ATRA and/or Arsenic Tri-oxide

Background: Acute promyelocytic leukemia (APML) is characterized by the reciprocal translocation t(15;17) (p22;p12) resulting in the PML-$RAR{\alpha}$ fusion gene. A dual diagnostic and follow up approach was applied including cytogenetic demonstration of the t(15;17) translocation and detection dg PML-$RAR{\alpha}$ chimeric transcripts by molecular means. Purpose: Conventional cytogenetics involving bone marrow is beset with high probability of poor metaphase index and was substituted with phytohemagglutinin (PHA)-induced peripheral blood culture based cytogenetic analysis as a diagnostic & follow up modality in APML patients of Kashmir (North India). Both qualitative (RT-PCR) and quantitative (Q-PCR) tests were simultaneously carried out to authenticte the modified cytogenetics. Materials and Method: Patient samples were subjected to the said techniques to establish their baseline as well as follow-up status. Results: Initial cytogenetics revealed 30 patients (81%) Positive for t(15;17) whereas 7 (19%) had either cryptic translocation or were negative for t(15;17). Two cases had chromosome 16q deletion and no hallmark translocation t(15;17). Q-PCR status for PML-$RAR{\alpha}$ was found to be positive for all patients. All the APML patients were reassessed at the end of consolidation phase and during maintenance phase of chemotherapy where 6 patients had molecular relapse, wherein 4 also demonstrated cytogenetic relapse. Conclusions: It was found that PHA-induced peripheral blood cytogenetics along with molecular analysis could prove a reliable modality in the diagnosis and assessment of follow up response of APML patients.
