A recent paper from this hospital (Morrison, Bass, Davis, Hobson, Madsen and Masters, 1957) reported that about one half of the children under 2 years of age admitted because of acute respiratory infections had haemoglobin concentrations below 11 g. per 100 ml. The purposes of the present investigation were to determine the distribution of the haemoglobin levels in children between 3 months and...

The issues of increasing the energy efficiency city-forming organizations ferrous metallurgy are considered in this paper. Ferrous is characterized by a high concentration organizations, social significance, and intensity. paper studies consumption metallurgy, highlights directions for use resources.

The effects of calcium, cupric, ferrous and ferric ions on the formation of trihalomethanes (THMs) and haloacetic acids (HAAs) were investigated using natural organic matter (NOM), small molecular weight NOM surrogates and natural water samples. The results showed that the effects were greatly dependent on the disinfection byproduct (DBP) precursor structure and molecular weight, and metal ions...

Genes of Sulfolobus metallicus that appeared to be upregulated in relation to growth on either ferrous iron or sulfur were identified using subtractive hybridization of cDNAs. The genes upregulated during growth on ferrous iron were found in a cluster, and most were predicted to encode membrane proteins. Quantitative reverse transcription-PCR of cDNA showed upregulation of most of these genes d...

In previous studies, three different strains (BrG1, BrG2, and BrG3) of ferrous iron-oxidizing, nitrate-reducing bacteria were obtained from freshwater sediments. All three strains were facultative anaerobes and utilized a variety of organic substrates and molecular hydrogen with nitrate as electron acceptor. In this study, analyses of 16S rDNA sequences showed that strain BrG1 was affiliated wi...

We randomised 120 patients who were undergoing either primary total hip or knee arthroplasty to receive either ferrous sulphate or a placebo for three weeks after surgery. The level of haemoglobin and absolute reticulocyte count were measured at one and five days, and three and six weeks after operation. Ninety-nine patients (ferrous sulphate 50, placebo 49) completed the study. The two groups ...

Ferrous lipoxygenases seem to be activated through a feedback control mechanism via fatty acid hydroperoxides generated from polyunsaturated fatty acids (PUFAs) by partially existing ferric lipoxygenases. However, during leukotriene synthesis, feedback activation of ferrous 5-lipoxygenase in the presence of arachidonic acid (AA) was not observed. In the present study, we examined the feedback a...

In cooking, food gels, such as agar-agar or alginate, are often prepared and presented in the form of spheres spaghetti. While experimenting our kitchen, we realized that it is quite difficult to make more advanced shapes. this study, sought develop new methods obtain complex Our first challenge was helices. The best method selected deposit solutions before their gelation a thread. robustness t...

In this study arsenate [As(V)] removal from drinking water by coagulation process was investigated. Ferric chloride (FeCl3.6H2O) and ferrous sulfate (FeSO4.7H2O) were used as coagulant. The effects of major operating variables such as coagulant dose (1–30 mg/L) and pH (5.5–9.5) were investigated. Ferric chloride and ferrous sulfate were found as effective and reliable coagulant due to required ...
