Bird dropping in terminology of stone deterioration pattern is a sub branch of deposit decay, means accumulation of exogenic materials, on stone surface, dropping has a main role in deterioration of buildings and stone monuments. Birds not only to build the nests and noisy cause to bother, but also due to transfer of variety disease into human, especially when it drops any place and then this d...

In an earlier study (Koretz, 1997), we reported that Kentucky had been unusually successful in testing most students with disabilities, but we found numerous signs of poor measurement, including differential item functioning in mathematics, apparently excessive use of accommodations, and implausibly high mean scores for some groups of students with disabilities. This study used newer data to te...

High school students who spend long hours in paid employment during the school year are at increased risk of lower grades and higher substance use, although questions remain about whether these linkages reflect causation or prior differences (selection effects). Questions also remain about whether such associations vary by socioeconomic status (SES) and race/ethnicity. This study examines those...

So you want to be a doctor? Well of course you do, but perhaps you’re exploring options beyond the usual UK courses. This could be for a variety reasons; perhaps you dropped a grade or got the grades but not the offer. Maybe the costs of university courses are giving you (or your parents) cold feet or perhaps you’d like to experience life abroad before you settle into your medical career? No ma...

Approximately one third of U.S. high-school freshmen do not earn their high-school diploma on time. For African-American and Hispanic students, this figure nearly reaches one half. The long-term economic consequences of dropping out of school for both the student and the larger community have been well documented. It has also been argued that school dropouts put themselves at a higher risk for ...

Our aim is to show the consistency of 2κ ≥ κ+θ, for any θ < κ starting with a singular cardinal κ of cofinality ω so that ∀n < ω∃α < κ(o(α) = α). Dropping cofinalities technics are used for this purpose. 1 א1-gap and infinite drops in cofinalities Let κ be a singular cardinal of cofinality ω such that for each γ < κ and n < ω there is α, γ < α < κ, such that o(α) = α. We fix a sequence of cardi...

This work considers a power control algorithm for cellular communications systems in which a user’s link quality objective, as measured by signal to interference ratio (SIR), varies with its transmitter power. In particular, as increased interference or reduced uplink gain leads a mobile to raise its transmitter power, that mobile lowers its SIR target. In this way, the likelihood of an infeasi...
