This paper reports an experimental study regarding the influence of vertical oscillations on the natural convection heat transfer from a vertical channel. An experimental set-up was constructed and calibrated; the vertical channel was tested in atmosphere at 25o
C. The channel-to-ambient temperature difference was varied with the power supply to the electrical heater ranging between
15W to 70W divided into five levels. Data sets were measured under different operating condition from a test rig under six vibrating velocities (VVs) levels ranging from (5-30 m/s) in addition to the stationary state. The results show that the maximum heat transfer enhancement factor (E) occurs at Rayleigh number (Ra=2.328×103 ) and vibrational Reynol

Free radicals are reactive compounds, their excessive production is considered to be an important cause of oxidative damage in biomolecules causing degenerative diseases. Polyphenols are one of the most important groups of secondary metabolites of plants, which have an antioxidant activity depending on their properties as hydrogen donors. Echinops polyceras Boiss. (Asteraceae) is one of Echinops genus species that spread in Syria, Lebanon, and Palestine. Phytochemicals found in this species leaves have been extracted with gradient polarity solvents, and primary screening of the secondary metabolites was established. The phenolic compounds and flavonoids contents were determined. The free radicals scavenging act

A total of 551 water samples (drinking and raw water) were collected In this study, Aeromonas.hydrophila, were detected by biochemical tests and PCR (16s rRNA gene). The results of identification showed that A.hydrophila had recovery rate 63 isolates (49.21%). The results revealed that all A.hydrophila isolates were PCR positive or the 16S rRNA gene and the results of sequencing showed that two isolates of A.hydrophila(local isolates) had percentage similarities 100% with A. hydrophila ATCC 7966 in GenBank database .All strains had a minimal Inhibitory Concentration(MIC) distribution pattern for lead cetate rranged (900-1200 μg/ml), and mercury chloride ranged (40-80 μg /ml).

The antimicrobial potency of the crude ethanolic extracts from different Iraqi plants were evaluated . Further more, total sesquiterpene lactones and phenolic compounds were isolated and their antimicrobial activity attempted. The results indicated that crude extracts have no activity except that of Callistemon lanceolatus. Also, the sesquiterpene lactones and phenolic compounds isolated from Callistemon lanceolatus were the most significant antimicrobial active constituents of the studied plants.

The study aims to identify the level of health services provided in private suites to government hospitals from the perspective of the recipi

      The activity concentration of natural radioactivity levels, of artificial cesium and transfer factor from soil to plants in agricultural areas at Al- Yusiefya region were determined by using NaI (Tl) detector spectrometer. Ten species of leafy plants have been selected: Spinach, Parsley, Watercress, Lettuce, Rashad, Radish, Green onion, Turnip green, Green beet and Mint. The mean activity concentrations of ²³⁸U, ²³²Th, ⁴⁰K and ¹³⁷Cs in leafy vegetable samples were  12.4±3.8, 14.8±4.7, 283±93 and 1.06±0.99  Bg/kg, and in soil samples were 15.9±4.3, 16.1±5.2, 298.5±3.9, and 1.11±0.37 Bq/kg. The radiation hazard indices were evaluated (radium

This study includes collection of 70 swabs samples of burns from patients were
admitted in three hospitals (Baghdad, Al- Numaan and burns injuries Hospital). All
swabs samples were cultured on blood and MacConkey agar media to isolate and
identify pathogenic bacteria according to their morphological , biochemical and
growth characters. Growth of bacteria on selective media showed the following
results: Pseudomonas aeroginosa 44.28% , Klebsiella pneumonia 30% ,
Staphylococcu saureus 8.57% , Escherichia coli 4.28% , Proteus vulgaris 4.28 % ,
Enterobacter spp. 5.71% , Acinetobacter baumanni 2.89 %. Different concentrations
were prepared from leaves ethanolic crude extract of Catharanthus roseus , then the

In this study, A 320 clinical specimens were collected
fromIntensiveCareUnits, Surgery and burn units in educational Ramadi
hospital. The enrichment and isolation of A. baumannii from collected
specimens led to isolate 30 bacterial strains from 337 bacterial isolates with
rate (8.9%), which similar in morphology for that standard strains. The rate
of A. baumannii isolated from burn specimens was 80%, the wound specimens (13.33%), and sputum (6.67% The study detect resistance of A.
baumanniifor different antibiotics, All isolates showed multidrug resistant,
the isolates was 100% resistant for Ampicillin, Cefazolin, Cefotaxime,
Cloxacillin, Colistin and Trimethoprim, as showed high resistance to
carbapenems reach
