Ironing Mature WORK

Since the 2005 report, there have been several campaigns to raise awareness and halt the practice, including by the same development agency's German-Cameroonian Health Sector Program, which organized campaigns against incest, rape and breast ironing. Its partner on the report, RENATA, launched its first efforts in 2006 and Cameroonian journalist Chi Yvonne Leina founded the organization Gender Danger in 2012 to eradicate breast ironing. Khamis believes those efforts are having a positive effect.

While persuading women to stop the practice is important, addressing the issue with girls and women isn't enough. Breast ironing won't fix the deeper gender inequities that motivate mothers to hurt their daughters, even if they do so out of love. "Men should just respect women more," Khamis says, "[but] to change the whole culture is really hard."

Several large epidemiological studies have demonstrated that maternal anemia is associated with premature delivery, low birth weight, and increased perinatal infant mortality (see Table 9-1) (Allen, 1997; Garn et al., 1981; Klebanoff et al., 1991; Lieberman et al., 1988; Murphy et al., 1986; Williams and Wheby, 1992). Some of these studies have been criticized because maternal hemoglobin concentration was measured only at the time of delivery. Physiological factors cause the maternal hemoglobin concentration to rise shortly before delivery. Delivery, occurring early because of known or unknown factors unrelated to anemia, could therefore be expected to show an association with a lower hemoglobin concentration even though anemia played no causal role. Other surveys have shown the association to be present even when hemoglobin concentration was measured earlier in pregnancy. In one recent prospective study, only anemia resulting from iron deficiency was associated with premature labor (Scholl et al., 1992). Furthermore, Goepel and coworkers (1988) reported that premature labor was four times more frequent in women with serum ferritin concentrations below 20 μg/L than in those with higher ferritin concentrations, irrespective of hemoglobin concentration.

While the observations relating iron status of the mother to the size of stores in infants (based on serum ferritin concentration) are important, it should be noted that the total iron endowment in a newborn infant is directly proportional to birth weight (Widdowson and Spray, 1951). Maternal iron deficiency anemia may therefore limit the infant's iron endowment specifically through an association with premature delivery and low birth weight. Preziosi and coworkers (1997) evaluated the effect of iron supplementation during pregnancy on iron status in newborn babies born to women living in Niger. The prevalence of maternal anemia was 65 to 70 percent at 6 months gestation. The iron status of the infants was also evaluated at 3 and 6 months of age. Although there were no differences between the supplemented and unsupplemented women in cord blood iron indexes at both 3 and 6 months of age, the children born to iron-supplemented women had significantly higher serum ferritin concentrations. Furthermore, it was reported that Apgar scores were significantly higher in infants born to supplemented mothers. There were a total of eight fetal or neonatal deaths, seven in the unsupplemented group.

Erythrocyte Protoporphyrin Concentration. Heme is formed in developing erythrocytes by the incorporation of iron into protoporphyrin IX by ferrochetalase. If there is insufficient iron for optimal hemoglobin synthesis, erythrocytes accumulate an excess of protoporphyrin, which remains in the cells for the duration of their lifespans (Cook, 1999). An increased erythrocyte protoporphyrin concentration in the blood therefore indicates that the erythrocytes matured at a time when the iron supply was suboptimal. The cut off concentration for erythrocyte protoporphyrin concentration is greater than 70 μg/dL of erythrocytes. Erythrocyte protoporphyrin concentration is again not specific for iron deficiency and is also associated with inadequate iron delivery to developing erythrocytes (e.g., anemia of chronic disease) or impaired heme synthesis (e.g., lead poisoning). In iron deficiency, zinc can be incorporated into protoporphyrin IX, resulting in the formation of zinc protoporphyrin (Braun, 1999). The zinc protoporphyrin:heme ratio is used as an indicator of impaired heme synthesis and is sensitive to an insufficient iron delivery to the erythrocyte (Braun, 1999).

Components of Requirement. Until menstruation resumes, assumed to be after 6 months of exclusive breast feeding, median iron needs during lactation are estimated as the sum of iron secretion in human milk and basal iron losses calculated for nonpregnant, nonlactating women (0.896 mg/day). The derived estimate of iron secreted in mature human milk is 0.27 0.089 (SD) mg/day (0.35 mg/L 0.78 L/day) (Table 9-5 and Chapter 2). Therefore, the median total requirement for absorbed iron is 1.17 mg/day (0.896 mg/day + 0.27 mg/day). For adolescent lactating mothers, the approach was identical to the one above except that in addition to basal losses (0.85 mg/day) and milk secretion (0.27 mg/day), provision was made for the deposition of iron in tissues (0.001 mg/day) and hemoglobin mass (0.14 mg/day) (see Table 9-10) as part of expected growth of the mother. Thus, the median requirement for absorbed iron is 1.26 mg/day (0.85 + 0.27 + 0.001 + 0.14). Again, a simulation model was used to derive the ninety-seven and one-half percentile of need.

Estimation of the Variability of Requirements. The variability of requirement was based on basal needs modeled as described for nonpregnant, nonlactating women and milk secretion modeled from the above distribution. Large breast-feeding studies suggest CVs between 10 and 40 percent (Dewey and Lonnerdal, 1983; Vaughan et al., 1979). A CV of 30 percent was adopted and iron concentration of mature human milk, for the purpose of modeling, is taken as 0.35 mg/L assuming normality with a CV of 33 percent.

Using IronX saves time and helps avoid the laborious claying process used in traditional car care regimes. This formulation of CARPRO IronX is safe and effective for use on all car surfaces and will not deteriorate clear coats. This preventative measure puts a stop to pre-mature corrosion.

The ironing process is far easier than a full re-glue and the results are good, but a good long cure time is important. First, let the skins cool to the touch before removing parchment (if used). Second, hang the skins in a safe place where they will be undisturbed for 24 hours before folding them glue to glue.

Two monoclonal antibodies specific for different rat T-cell subpopulations, the anti-helper-T-cell antibody, W3/25, and the OX8 suppressor cell antibody were used to investigate lectin-stimulated T-lymphocyte differentiation of F-344 rat bone marrow cells in culture. Cytofluorometric analysis of freshly isolated lymphocytes from thymus and spleen revealed that these tissues contained both W3/25- and OX8-positive populations but differed with respect to the number of cells and receptor density distribution. By contrast, bone marrow-derived lymphocytes exhibited negligible W3/25- or OX8-associated fluorescence. However, several days after stimulation of bone marrow lymphocytes with phytohemagglutinin (PHA), cells appeared bearing these markers. Two-parameter histogram analysis of light scatter measurements with cell surface immunofluorescence indicated that this phenomenon represented the appearance of a new population of cells, presumably mature T cells, bearing an increased density of marker. These findings suggest an induction of differentiation of bone marrow T precursor cells by nonthymic factors (PHA) since lymphocytes lacking mature T-cell marker expression developed this characteristic after several days in culture.

Yes, women with curly hair face challenges that straight-haired women can never understand. They take extreme measures to straighten their hair, at times facing the kind of danger associated with working on fallen electrical lines. There was the ironing board to flatten curls. There were chemicals of uncertain provenance. The complicated science of caring for - or annihilating - curls has spawned high-priced salons that cater to women with curly hair.

I sit next to Hayley, a nightclub deejay from the hip East Village. She declines to give her last name, but she doesn't mind sharing her straight hair visions. "Straight hair is more mature, professional, and easier.... and when it's straight," she bubbles informatively, "I get a lot more attention from guys than when it's curly."

At the core of this story is environmental data science, a field that serves to improve the analysis and synthesis of diverse and often vast amounts of data to address environmental challenges. With expanding amounts of environmental data at our finger tips, data science is critical to harvesting insights from them that can inform decision-making. Yet, still a nascent field, environmental data science needs advocates and cultivators to mature as a discipline. 041b061a72
