in this paper, some results of singh, gopalakrishna and kulkarni (1970s) have been extended to higher order derivatives. it has been shown that, if $sumlimits_{a}theta(a, f)=2$ holds for a meromorphic function $f(z)$ of finite order, then for any positive integer $k,$ $t(r, f)sim t(r, f^{(k)}), rrightarrowinfty$ if $theta(infty, f)=1$ and $t(r, f)sim (k+1)t(r, f^{(k)}), rrightarrowinfty$ if $th...

background : iodine deficiency produces the spectrum of iodine deficiency disorders (idds) including endemic goiter, hypothyroidism, cretinism and congenital anomalies. other factors, including goitrogens and micronutrient deficiencies may influence the prevalence and severity of idds and response to iodine supplementation. an ssociation between zinc and goiter has previously been reported. met...

Minerals are very important nutrients for dairy animal production. Deficiency of minerals may leads to certain structural, physiological or immunological disorder affecting growth, production and reproductive health of animals. Minerals deficiency is an area specific problem and supplementation strategy must be revised accordingly. Requirements of minerals for reproduction and immunity are gene...

The prevalence of nutritional iron deficiency anemia in infants and toddlers has declined dramatically since 1960. However, satisfaction with this achievement must be tempered because iron deficiency anemia in infants and toddlers is associated with long-lasting diminished mental, motor, and behavioral functioning. Additionally, the prevalence of iron deficiency anemia in one- to three-year-old...

Vitamin D deficiency (VDD) is a global health issue that affects both industrialized and emerging countries. With prevalence rates across all age categories in India, vitamin the entire Indian continent. Regardless of fact there sufficient sunlight India which required for endogenous synthesis. Nutrient inadequacy probably going to play significant part exceptionally high pervasiveness osteopor...

As an efficient alternative to fossil fuels, renewable energy sources have attained great attention due to their sustainable, cost-effective, and environmentally friendly characteristic. However, as a deficiency, renewable energy sources have low reliability because of their non-deterministic and stochastic generation pattern. The use of hybrid renewable generation systems along with the storag...

Zinc is ubiquitous in all living cells. Structural and catalytic properties of cellular enzymes are zinc dependent. Zinc deficiency leads to a variety of pathological abnormalities with immune impairment. It is an established fact that nutritional status contributes to overall immune response of individuals. Outcome of zinc deficiency on immune system is so drastic that it is difficult to conce...
