Twelve million of these children die every year, and protein-energy malnutrition is implicated in more than 55% of all these deaths.

It also punishes the child, who has done nothing wrong. ...

  • We all know that keeping a positive attitude can affect our mental and physical health. So main- taining a certain amount of calm and acceptance about your circumstances can set the tone for your family interactions.

Of course, that’s not to say that you have to keep everyone’s spirits up all the time. You need to experience your own emotions and give them validation. The key is to not get caught up in your emotions and let them drag you down.

Much progress still remains to be made in infrastructure improvements and poverty reduction. A recent World Bank report, for example, noted that more than 100 million people in the Latin American region alone lack access to potable water and adequate sanitation systems. Compounding the issue of water availability is contamination of water supplies and the lack of wastewater treatment facilities.

About 20,000 water bodies are impacted by siltation, nutrients, bacteria, oxygen depletion substances, metals, habitat alterations, pesticides, and toxic organic chemicals. With pollution from point sources being dramatically reduced, nonpoint source pollution is the major cause of most water that does not meet water quality goals.

We draw on semi-structured interviews with young married women with at least one child under the age of six, in urban and rural areas of Rajasthan and Madhya Pradesh, north India, to elaborate differences in attitudes and experiences in early married life between young married women with at least eight years of schooling and those with little or no formal schooling.

The precise amount necessary cannot be fixed at any particular sum; perhaps five parts in a hundred would be as good a quantity as could be recommended.

  • Malignant germ cell tumors are usually large (median—16 cm). Bilateral disease is rare except in dysgerminoma (10–15% bilaterality). Abdominal or pelvic pain in young women is the usual presenting symptom.

Before the advent of chemotherapy, extensive surgery was routine, but it has now been replaced by careful evaluation of extent of spread, followed by resection of bulky disease and preservation of one ovary, the uterus, and the cervix, if feasible.

These traits are important since they affect the herd size and off take. Reproductive performance is commonly evaluated by analysing female reproductive traits. The traits regularly considered include age at first calving, calving interval and calving rate. Male fertility traits are rarely included in genetic evaluations despite their influence on the female reproductive performance.
