background : diabetes mellitus is a chronic disease with a worldwide prevalence and its complications can be prevented with close monitoring of blood glucose. quality of blood glucose monitoring utilizing glucometers in iranian hospitalized patients has not been well published in the literature. we evaluated the accuracy and consistency of the results of two devices compared with the standard l...

A total of 557 newborn piglets were used to compare eight identification devices, including one plastic ear tag as a control (C, n = 348) and two types of electronic ear tags (E1, n = 106; and E2, n = 103), and five types of injectable transponders (n = 557): small 12-mm (D12, n = 116; and S12, n = 110), medium 23-mm (T23, n = 108), and large (32-mm, T32, n = 115; and 34-mm, S34, n = 108). Inje...

Longitudinal studies of hearing in workers in selected industries in Canada have shown that the effect of continuous high-level noise exposure is an increase in detection threshold of about 1 1/2 decibels per year. This is in contrast to 1/2 dB per year for non noise-exposed office workers in the same plants. Personal hearing protectors, in the form of ear plugs and muffs, have been chosen as a...

The potential risk to hearing that mass-storage personal listening devices (PLDs) pose remains unclear. Previous research in this area has either focused on maximum outputs of these devices or on ear-canal measurements of listening levels that could not be compared to standards of occupational noise exposure. The purpose of this study was to compare two standard measurement protocols [ISO 11904...

This article was investigated to study the correlation and analysis of drought stress regression on maize cultivars' yield components. The variance results showed a significant difference between levels in terms plant height, total dry weight number seeds per row, cob, grain yield, harvest index, stem diameter, cob with protective leave. Also, there ear without leaves, length, weight, 100-seed ...

Mobile technologies for the recording of vital signs and neural signals are envisaged to underpin the operation of future health services. For practical purposes, unobtrusive devices are favoured, such as those embedded in a helmet or incorporated onto an earplug. However, these locations have so far been underexplored, as the comparably narrow neck impedes the propagation of vital signals from...

Introduction: Radiography plays an important role in the diagnosis of oral and dental disease and one of the most common diagnostic procedures in dentistry. Recent reports have raised concern about the increased use of ionizing radiation in dental imaging and the possibility of cancers. The effective dose of some dental radiographic examinations is high enough, so appropriate ...

The novel once-daily β₂-agonist bronchodilator drug olodaterol has recently been shown to be effective in patients with allergic asthma for >24 hours. An increased cholinergic tone common to these patients may decrease the effectiveness of β₂-agonists. This could provide a rationale for combination therapy with olodaterol and the long-acting anticholinergic tiotropium to aim for a once-daily tr...
