    • A diagnostic tool for family and marriage counseling with Muslim couples 

      Soliman, Abdrabo; Abdel-Salam, Abdel Salam G.; Ahmed, Mervat ( Springer Nature , 2022 , Article)
      This study aimed to describe the development and psychometric properties of a questionnaire for Muslim couples and families based on how couples view and experience marital and family issues. A questionnaire was developed ...

    • Effect of asymmetrical heat rise/fall on the film flow of magnetohydrodynamic hybrid ferrofluid 

      Tlili, Iskander; Mustafa, M. T.; Kumar, K. Anantha; Sandeep, N. ( Springer Nature , 2020 , Article)
      The movement of the ferrous nanoparticles is random in the base fluid, and it will be homogeneous under the enforced magnetic field. This phenomenon shows a significant impact on the energy transmission process. In view ...

    • The effect of graphene on the activation energy of grain growth for the nanocrystalline thermoelectric n-type Bi2Te2.7Se0.3 

      El-Makaty, Farah M.; Pothuvattil, Nandagopal S.; Hamouda, Abdelmagid; Youssef, Khaled M. ( Springer Nature , 2022 , Article)
      Even though bismuth telluride is frequently produced by mechanical alloying for thermoelectric materials, no data has been published addressing the thermal behavior and activation energy of the milled n-type Bi2Te2.7Se0.3 ...

    • Electrospun Polysulfone Hybrid Nanocomposite Fibers as Membrane for Separating Oil/Water Emulsion 

      Ponnamma, Deepalekshmi; Elgawady, Yara; Hassan, Mohamed K.; Adham, Samer; Al-Maas, Mashael; ... more authors ( Springer Nature , 2023 , Article)
      Commercial polymer membranes are largely utilized to separate oil/water mixtures; however, membrane fouling, flux decline, and short lifetime often inhibit their high performance. In order to resolve these drawbacks of the ...

    • Frequency conversion layers for Si solar cell efficiency improvement 

      Gourbilleau, Fabrice; Dumont, Lucile; Cardin, Julien; Gouesmel, Anaïs; Yu, Ing Song; ... more authors ( Springer Nature , 2017 , Book chapter)
      SiNx and SiNx: Tb3+ thin layers deposited by reactive magnetron co-sputtering have been studied with the aim of optimizing the light management in Si solar cells. Those Si-based layers are developed to be compatible with ...

    • Level sets of potential functions bisecting unbounded quadrilaterals 

      Nasser, Mohamed M.S.; Nasyrov, Semen; Vuorinen, Matti ( Springer Nature , 2022 , Article)
      We study the mixed Dirichlet–Neumann problem for the Laplace equation in the complement of a bounded convex polygonal quadrilateral in the extended complex plane. The Dirichlet / Neumann conditions at opposite pairs of ...

    • OpenFOAM for computational combustion dynamics 

      Muhammad, Noor; Zaman, F. D.; Mustafa, M. T. ( Springer Nature , 2022 , Article)
      In computational fluid dynamics (CFD), the mathematical description of a physical phenomenon that involves fluid flow, combustion, and chemical reaction is combined with a numerical solution of the problem via the use of ...

    • Polycircular domains, numerical conformal mappings, and moduli of quadrilaterals 

      Nasser, Mohamed; Rainio, Oona; Rasila, Antti; Vuorinen, Matti; Wallace, Terry; ... more authors ( Springer Nature , 2022 , Article)
      We study numerical conformal mappings of planar Jordan domains with boundaries consisting of finitely many circular arcs, also called polycircular domains, and compute the moduli of quadrilaterals for these domains. ...

    • Prevalence of hepatitis B and C viruses among migrant workers in Qatar. 

      Nasrallah, Gheyath K; Chemaitelly, Hiam; Ismail, Ahmed I A; Nizamuddin, Parveen B; Al-Sadeq, Duaa W; ... more authors ( Springer Nature , 2024 , Article)
      Limited data exist on viral hepatitis among migrant populations. This study investigated the prevalence of current hepatitis B virus (HBV) infection and lifetime hepatitis C virus (HCV) infection among Qatar's migrant craft ...
