Present research focus on novel combination of Rifampicin, Ofloxacin and Ethambutol loaded polymeric nanoparticles for the effective eradication of isoniazid resistant species of Tuberculosis. The nanoparticles containing Rifampicin, Ethambutol and Ofloxacin were prepared by spray drying technique using biodegradable polymer PLGA through critical process as well as polymer attributes which were...

Background: Bootstrap is a computer simulation-based method that provides estimation accuracy in estimating inferential statistical parameters. Purpose: This article describes a research using secondary data (n = 30) aimed to elucidate bootstrap method as the estimator of linear regression test based on the computer programs MINITAB 13, SPSS 13, and MacroMINITAB. Methods: Bootstrap regression m...

As the demand for refrigeration and Air conditioning has been increased during the last decade, the cold storage system can be used to the economic advantage over conventional plants. Energy conservation is required in the cold storage system so The Design of Experiment is used to Optimization of different parameters of cold storage on the bases of performance experiments. In This Experiment, t...

This work aims to study the production of the biomass of S. cerevisiae on an optimized medium using date extract as the only carbon source in order to obtain a good yield of the biomass. The biomass production was carried out according to the central composite experimental design (CCD) as a response surface methodology using Minitab 16 software. Indeed, under optimal biomass production conditio...

Sir, We read with interest the paper of Guarrera & Rebora (1) on the hydrosoluble antioxidant capacity (HAOC) of serum of patients with polymorphic light eruption (PLE). We were involved in a similar study that aimed to establish the role of uric acid in total HAOC. In particular, Guarrera & Rebora observed that the total HAOC is reduced in females regardless of whether they are patients or con...

A novel dispersive liquid-liquid microextraction (DLLME) method followed by HPLC analysis, termed sequential DLLME, was developed for the preconcentration and determination of aryloxyphenoxy-propionate herbicides (i.e. haloxyfop-R-methyl, cyhalofop-butyl, fenoxaprop-P-ethyl, and fluazifop-P-butyl) in aqueous samples. The method is based on the combination of ultrasound-assisted DLLME with in si...

In the current study, an optimization process of powder-mixed electrical discharge machining (PMEDM) when cylindrically shaped parts made hardened 90CrSi steel is reported. this SiC powder was mixed into Diel MS 7000 dielectric solution. Additionally, graphite chosen as electrode material. The multi-objective functions were minimizing surface roughness (SR) and wear rate (EWR) maximizing materi...

Bumper and crash boxes are vehicle structural elements that convert the collision (kinetic) energy at into deformation energy. Failure of bumper system to sufficiently absorb in event a will result resulting forces being transferred directly driver passenger area. It deaths or injuries people further damage vehicle. In this study, performance an existing aluminum produced by extrusion method wi...

The goal of this project is to see how different drilling parameters like spindle speed (600, 900, 1400 revolution per minute), feed rate (0.10, 0.16, 0.22 mm revolution) and drill tool diameter (6, 8 mm) affect surface roughness, material removal wear while Al 6063 alloy with an HSS spiral using Taguchi method. impact settings on the accuracy drilled hole analyzed S/N (signal-to-noise) ratio, ...

Our objective was to examine if a co-curricular activity incorporated with assessment methods affected students’ competence in course. Natural Sciences (201) chosen as candidate course for this study. Students’ grade breakdown examined and analyzed using SPSS MINITAB software over four academic years from Fall 2012-13 2015-16. The number of failed male students significantly lower (p<0.05) s...
