Particle Spectroscopy of Supersymmetric SO(10) with Non-Universal Gaugino Masses

We examine the low scale particle spectroscopy of an SO(10) (or equivalently SU(5)) inspired supersymmetric model with non-universal gaugino masses. The model assumes minimal supergravity and contains the same number of fundamental parameters as the constrained minimal supersymmetric model (CMSSM.) Realistic solutions compatible with dark matter and other applicable experimental constraints are shown to exist for both positive and negative signs of the MSSM parameter mu. We present several benchmark points which will be tested at the LHC and by the ongoing direct and indirect dark matter detection experiments.Comment: 18 pages,10 figures, 9 table

Top Quark and Higgs Boson Masses in Supersymmetric Models

We study the implications for bounds on the top quark pole mass m_t in models with low scale supersymmetry following the discovery of the Standard Model-like Higgs boson. In the minimal supersymmetric standard model, we find that m_t >= 164 GeV, if the light CP even Higgs boson mass m_h = 125 +-2 GeV. We also explore the top quark and Higgs boson masses in two classes of supersymmetric SO(10) models with t-b-tau Yukawa coupling unification at M_GUT. In particular, assuming SO(10) compatible non-universal gaugino masses, setting m_h = 125 GeV and requiring 5% or better Yukawa unification, we obtain the result 172 GeV <= m_t <= 175 GeV. Conversely, demanding 5% or better t-b-tau Yukawa unification and setting m_t=173.2 GeV, the Higgs boson mass is predicted to lie in the range 122 GeV <= m_h <= 126 GeV.Comment: 16 pages, 7 figure

Assessment of Metered-Dose Inhalers with Spacer Technique among Postgraduate Trainees

OBJECTIVES Most obstructive airway disease medications are used via inhalers, and their proper use is significant for effectively treating these diseases. Most patients misuse it. However, some studies showed that many physicians also do not know the proper meter dose inhaler with the spacer technique. This study aimed to assess metered-dose inhalers with spacer technique among postgraduate trainee doctors. METHODOLOGY This cross-sectional study was carried out in the Khyber Teaching Hospital Peshawar. The total time was six months, from Dec 6 2020, to Jun 5 2021. Postgraduate trainee (PGT) doctors of either gender with an age range of 25 to 35 years were included in the study from different departments. Those with every use of inhalers were excluded from the study. Demographic details of PGTs, like age and gender, were recorded. RESULTS Among 96 patients, males were 85 (88.54%), and females were 11 (11.46%). The mean age was 30.02±1.84 years, and the mean training experience was 2.0521 ±0.89. Inhaler technique was Proper in 20 (20.83%), Improper in 51 (53.13%) and Poor in 25 (26.04%) doctors. Those with more training periods, pulmonology rotation, attended workshops on inhaler techniques and with relatives using inhalers were more acknowledged of proper meter dose inhalers (MDIs) with spacer technique. CONCLUSION Only one-fifth of the postgraduate trainees know proper MDIs techniques. The attendance of workshops and pulmonology rotation is encouraged to enhance the knowledge of physicians regarding MDIs techniques

The robust catalysts (Ni1−–Mo /doped ceria and Zn1−–Mo /doped ceria, x = 0.1 and 0.3) for efficient natural gas reforming in solid oxide fuel cells

Nickel is a promising catalyst in Solid Oxide fuel cell (SOFC) due to its electrocatalytic performance, however, the practical utilization of Ni-based materials is hindered by the undesirable carbon deposition during methane decomposition. Herein, molybdenum is incorporated into the Ni- and Zn-based cermets (Ni1−x–Mox/GDC and Zn1−x–Mox/GDC, x = 0.1 and 0.3) to enhance electrocatalytic properties and avoid the carbon deposition during cell operation. The desired composites are synthesized by the impregnation method and adopted as anode in SOFCs. The catalytic activity for methane oxidation has been significantly improved due to the introduction on Mo, which hindered the carbon deposition due to higher graphitization and abundant active sites accessible to fuel. The detailed Raman spectroscopy and conductivity analysis revealed that addition of Mo reduced the amount of deposited carbon and enhanced the electrical conductivity. By using natural gas, as a fuel, the as-prepared Mo-doped Ni–GDC rendered a maximum power density of 690 mW cm−2 at 600 °C. It is worth mentioning that the achieved stable power density is one of the best in existing literature. The current study presents a novel strategy to improve the catalytic behavior of electrode materials and demonstrate the optimal performance at low operating temperature
