Objectives: Assessment outcome of DOTS (Directly observed therapy short course) program in Al-Sader City
Sector that was established by the WHO.
Methodology: Three cohorts groups of patients attending Baghdad TB institute and TB center in Al-Sader city
were followed retrospectively. The 1st cohort included (314) patients registered in year (2003), the 2nd cohort
included (327) patients registered in year (2004), the 3rd cohort included (321) patients registered in year
(2005). The collected data were analyzed for case detection, treatment outcomes, retreatment outcomes,
treatment success, and retreatment success in regard to time, age and sex.
Results: The following rates were extracted for the three cohort: Case detection rate within 1st, 2nd, and 3rd
cohort were (73.36%, 64.24%, and 71.49% respectively).Treatment outcomes (cured, completed treatment,
defaulters, treatment failure, died and transfer out) of new smear positive patients within the 1st, 2nd and 3rd
were (71.7%, 12.7%, 10.2%, 3.5%, 1%, 1%), (64.8%, 19.9%, 0.9%, 7%, 0.6%, 6.7%) and (61.4%, 24%, 3.1%, 5.9%,
0.6%, 5% respectively).Retreatment outcomes (cured, completed treatment, defaulters, treatment failure, died
and transfer out) within 1st, 2nd and 3rd cohort were (55.6%, 7.9%, 6.6%, 15.2%, 4%, 10.6%), (44.9%, 7.7%,
2.6%, 21.8%, 4.5%, 18.6%) and (41.8%, 14.6%, 11.4%, 19.6%, 1.9%, 10.8% respectively. Treatment success rate
within the 1st, 2nd and 3rd cohort were (84.39%, 84.7%, and 85.35%) respectively. Retreatment success rate
within the 1st, 2nd and 3rd cohort was (63.57%, 52.56%, and 56.32%) respectively.
Recommendation :Increase case detection rate through increase health awareness to the community about
the mode of transmission and risk of TB disease, Increase the training of health team so that they can follow up
of patients at home, Increase follows up of defaulters to be able to deal with them and a study for relapses
cases is recommended
A simple physical technique was used in this study to create stable and cost-effective copper oxide (CuO) nanoparticles from pure copper metal using the pulsed laser ablation technique. The synthesis of crystalline CuO nanoparticles was confirmed by various analytical techniques such as particle concentration measurement using atomic absorption spectrometry (AAS), field emission scanning electron microscopy (FE-SEM), the energy dispersive X-ray (EDX), and X-ray diffraction (XRD) to determine the crystal size and identify of the crystal structure of the prepared particles. The main characteristic diffraction peaks of the three samples were consistent. The corresponding 2θ is also consistent, and the cytotoxicity of the nanoparticles was

To assess the contribution of Doppler broadening and examine the
Compton profile, the Compton energy absorption cross sections are
measured and calculated using formulas based on a relativistic
impulse approximation. The Compton energy-absorption cross
sections are evaluated for different elements (Fe, Zn, Ag, Au and Hg)
and for a photon energy range (1 - 100 keV). With using these crosssections,
the Compton component of the mass–energy absorption
coefficient was derived, where the electron momentum prior to the
scattering event caused a Doppler broadening of the Compton line.
Also, the momentum resolution function was evaluated in terms of
incident and scattered photon energy and scattering angle. The res

In this study, manganese dioxide (MnO₂) nanoparticles (NPs) were synthesized via the hydrothermal method and utilized for the adsorption of Janus green dye (JG) from aqueous solutions. The effects of MnO₂ NPs on kinetics and diffusion were also analyzed. The synthesized NPs were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), energy-dispersive X-ray analysis (EDX), and Fourier-transform infrared spectroscopy (FT-IR), with XRD confirming the nanoparticle size of 6.23 nm. The adsorption kinetics were investigated using three models: pseudo-first-order (PFO), pseudo-second-order (PSO), and the intraparticle diffusion model. The PSO model provided the best fit (R² = 0.999), indicating that the adsorpti

The melting duration in the photovoltaic/phase-change material (PV/PCM) system is a crucial parameter for thermal energy management such that its improvement can realize better energy management in respect to thermal storage capabilities, thermal conditions, and the lifespan of PV modules. An innovative and efficient technique for improving the melting duration is the inclusion of an exterior metal foam layer in the PV/PCM system. For detailed investigations of utilizing different metal foam configurations in terms of their convective heat transfer coefficients, the present paper proposes a newly developed mathematical model for the PV/PCM–metal foam assembly that can readily be implemented with a wide range of operating condition
