چکیده
One of the most important resources we need today is electricity to carry out comfortably our day-to-day activities. While many nations in the world are abundantly enjoying this resource, more than 1.2 billion people do not have access to electricity. Most of these people are from developing nations typically from Africa and India. They happen to be poor and living in remote villages and mountainous terrains. Several agencies like the World Bank, UNDP, IEA and some developed countries are already taking steps to alleviate this energy poverty with the aim to achieve universal access to electrical power by the year 2030. These efforts are being implemented through well-known methods of electrical power production—both renewable as well as other types, one of which is harvesting the solar energy. As we know, sunlight is not available continuously, 24 hours per day. But what if we could make it so? Since one half the earth’s hemisphere does have sunlight, while the other half experiences night time, what if donor countries having the sunshine store the solar energy so it could be used during the night in receiver countries augmented by other types of electrical

Administration of recombinant human interleukin-7 to mice induces the exportation of myeloid progenitor cells from the bone marrow to peripheral sites.
The administration of recombinant human interleukin-7 (rhIL-7) to mice twice a day for 7 days does not appreciably change bone marrow (BM) cellularity, but does result in a threefold to fivefold increase in the total number of leukocytes in the spleen, an eightfold to 10-fold increase in the total number of nonparenchymal cells (NPC) obtained from the liver, and up to a 20-fold increase in the ...

متن کاملGenomic DNA Copy-Number Alterations of the let-7 Family in Human Cancers
In human cancer, expression of the let-7 family is significantly reduced, and this is associated with shorter survival times in patients. However, the mechanisms leading to let-7 downregulation in cancer are still largely unclear. Since an alteration in copy-number is one of the causes of gene deregulation in cancer, we examined copy number alterations of the let-7 family in 2,969 cancer specim...
متن کاملInequalities Involving Independence Domination , / - Domination , Connected and Total / - Domination Numbers
Let / be an integer-valued function defined on the vertex set V(G) of a graph G. A subset D of V(G) is an /-dominating set if each vertex x outside D is adjacent to at least f(x) vertices in D. The minimum number of vertices in an /-dominating set is denned to be the /-domination number, denoted by 7/(G). In a similar way one can define the connected and total /-domination numbers 7 C| /(G) and...
متن کاملOn the number of prime factors of an odd perfect number
Let Ω(n) and ω(n) denote respectively the total number of prime factors and the number of distinct prime factors of the integer n. Euler proved that an odd perfect number N is of the form N = pem2 where p ≡ e ≡ 1 (mod 4), p is prime, and p ∤ m. This implies that Ω(N) ≥ 2ω(N) − 1. We prove that Ω(N) ≥ (18ω(N) − 31)/7 and Ω(N) ≥ 2ω(N) + 51.
متن کاملThe distribution and number of Leu-7 (CD57) positive cells in lung tissue from patients with pulmonary fibrosis.
Leu-7 positive lymphocytes, including natural killer cells, play an important role in the immune system's surveillance function to prevent the development of cancer. The incidence of lung cancer is significantly high in patients with end-stage pulmonary fibrosis. We hypothesized that the number of Leu-7 positive cells may be decreased in areas of severe pulmonary fibrosis. To demonstrate this, ...
