comparative macro- and micromorphology of the leaves, stems and stems and seeds of Vicia sative 1, Vicia calcarate desf and Vicia faba L, [var Minor] growing in Egypt

A macro- and micromorphology of the leaves, stems and seeds of Vicia sativa L., V. calcarata Desf, and V. faba L. [var. Minor] growing in Egypt are presented for the sake of their identification and differentiation in both entire and powdered forms

Aspects hygieniques de la fermentation aerobie des dechets urbains dans le contexte Tunisien

The use of the aerobic fermentation [composting] as an alternative of the landfilling of the municipal solid wastes was studied in a pilot plant in the District of Tunis. The effectiveness of the composting, by the windrow turning technical, in producing sanitized compost was considered. Fecal coliforms, fecal streptococcis and E. coli were used as an indicator organism. In addition, the evolution of the process was monitored using sporogenous bacteria. Under the experimental conditions, approximately five logarithmic unit reduction of fecal indicators was noted after a 60 days composting

Cytotoxicity of ferric chloride used as adjuvant of organic acid precipitation

The objective of this study was the amelioration of the organic acid precipitation technique currently used as a secondary stage for viruses concentration using ferric chloride [FeCI [3]] as an adjuvant. To carry out this work successfully, we have studied the cytotoxicity effect of FeCI [3] towards cell lines usually used for the investigation of enteric viruses. Two kinds of african green monkey kidney cells, MA104 and BGM, were used as a cellular model. The results showed that optimum concentration of FeCI [3] for either BGM or MA104 cell survival and organic acid precipitation varies from 0.5 to 1 mM. The cytotoxicity test used in this work was simple, easy to realize and gives an appreciable information about the cytotoxicity dose of a given biological and chemical product

Agriculture valorization of treated waste water Evaluation of bacteriologic contamination of soil tables and plants

The present study aim was to valorize the treated waste water as source of fertilizers for vegetables seed production and to assess the eventual bacteriological contamination risks of soil, plant and phreatic ground water table. The bacteriological analysis of drained water did not reveal any fecal coliforms vertical migration in depth and a low fecal contamination [thermotolerant coliforms] is limited to the levels of superficial horizons. The seed produced by using waste water showed a slighty fecal contamination which disappeared following treatment with a [5% chlorid solution]. The treated waste water improve the onion seeds production per hectar in spite of the increases of the phytopathogenic hazards

research method of enterovirus in milk

A method of detection of enteric viruses in milk was studied. The high protein content of milk and the protein nature of enterovirus allowed the detection of these viruses using the organic acid floculation method. The poliovirus type 1 [Mahoney strains] and the E.C.H.O.1 isolated from the environment were used as virus model and were inoculated to creamed, half-creamed and whole UHT commercialized milk. The method consists of a milk sample clarification with acid precipitation and centrifugation. The clarified extract is reduced to a final volume of 10 to 15 ml after addition of beef extract powder and protein precipitation. This technique allows the recovery of 26 to 36% of poliovirus type 1 and 10 to 46% of E.C.H.O.1 viruses. In this work, the ferric chloride [FeCI [3]], added in 0.5 to 1 mM final concentration, was used as an adjuvant for the organic acid precipitation

Assessment of knowledge related to birth spacing among Saudi mothers in Riyadh city: part I

The objectives of the study are to identify the birth spacing knowledge levels among Saudi mothers in the three selected primary health care centres; and determine the correlation between the knowledge scores and certain demographic and ubstetrical variables .One-hundred fifty Saudi pregnant women participated in the study. Data was collected through the interview method. The instrument was tested for face validity and reliability. Data was analyzed manually. The result reflects that the majority of Saudi mothers had poor birth spacing knowledge scores. There is no significant difference in knowledge scores among the three centres. Birth spacing knowledge scores are directly related with the level of education and No. of low birth weight babies. But no relation between spacing knowledge scores and number of pregnancies deliveries living children and abortions

Assessment of knowledge related to nutrition during pregnancy and lactation among Saudi mothers in Riyadh city

The objectives of the study are to identify the nutrition knowledge levels among Saudi mothers in the three selected primary health care centres and determine the correlation between the knowledge scores and certain demographic and obstetrical variables. The study was conducted at three selected centres. One hundred fifty Saudi pregnant women participated in the study. Data was collected through the interview method. The instrument consisted of three parts demographic, obstetrical data, questions pertaining to nutrition during pregnancy and lactation and the sources of information used by the respondents. Instrument was tested for validity and reliability, the results, show that there is no significant difference in knowledge scores among the three centres, nutrition knowledge scores are inversely correlated with the number of pregnancies deliveries and living children but do not correlate with age
