the development of a surface water evaluation index is a critical factor in the assessment, restoration and protection of stream water quality. quantifying water pollution in specific grade using dominant parameters is important, as this can explain the current state of water pollution with accuracy. as a result, an integrated multi-parameter water quality index has been developed. it is based ...

The microbiological quality of 75 private drinking water supply boreholes in Co. Cork, Ireland was assessed in order to determine the incidence of contamination and the potential pathways of such contamination. Microbiological analysis was carried out using the membrane filtration technique for the recovery of thermotolerant (faecal) coliforms. The sanitary protection of the supplies was evalua...

BACKGROUND Water treatment systems are a critical variable in dialysis therapy. Rigorous control of hemodialysis water quality is particularly important in order to guarantee a better quality of life of the hemodialysis patients. The objective of the study was to evaluate the chemical, microbiological quality and antimicrobial resistance of bacteria isolated from water and dialysate in a public...

The objectives of this study were to assess the microbiological quality of Egyptian yoghurt and to investigate the antagonistic activity of some probiotic bacteria against some food borne pathogens in vitro and in yoghurt. The results indicated a poor microbiological quality of yoghurt, since the microbiological parameters recorded higher values than the admissible levels. Results from the agar...

BACKGROUND The periodontal disease during pregnancy of women with rheumatic valve disease imply infective endocarditis risks and higher rate of preterm birth and low birth weight. OBJECTIVE To study the periodontal disease rate of women with rheumatic valve disease during pregnancy. METHODS We studied 140 pregnant women who included 70 patients with rheumatic valve disease and 70 healthy wo...

evaluation of voice quality parameters of esophageal speech in different neoglottis forms after total laryngectomy. methods: presentation of voice analysis of 20 patients, who underwent total laryngectomy. the success of acquiring this technique was estimated by means of a voice analyzing program (pitch, sound-holding, loudness, spectrogram), and by the intelligibility via the telephone. shape ...

introduction: filtering can greatly affect the quality of clinical images. determining the best filter and the proper degree of smoothing can help to ensure the most accurate diagnosis. methods: forty five patient’s data aquired during brain phantom spect studies were reconstructed using filtered back-projection technique. the ramp, shepp-logan, cosine, hamming, hanning, butterworth, metz and w...

Urban groundwater development was traditionally constrained by concerns about its quality. This study was conducted in the regions of La Ribera Alta and Ribera Baja and La Plana de Requena-Utiel of the Valencian Community (Valencia, Spain) where population density, demand for drinking water and agricultural activities are high. Groundwater bodies (GWBs) are regarded as management areas within e...
