The present study aimed to evaluate the effect of dipping time and temperature of hot water and type of packaging on qualitative traits of Orlando tangelo variety of tangerine. This study was conducted as a factorial experiment in a completely randomized design with three repeats. The treatments consisted of dipping in hot water at seven water levels at 53°C and 58°C each for 1, 2 and 4 minutes...
in this thesis, barium ferrite nano particles were prepared by sol-gel method. their structural and magnetic properties of samples have been investigated using thermo gravimetric analysis (tg-dta), x-ray powder diffractometer (xrd), fourier transform infrared (ftir), scanning electron microscopy (sem), field emission scanning electron microscopy (fesem), ac susceptometer, vibrating sample magne...
DFT calculations were applied to evaluate the electronic and magnetic properties of zigzag BC2Nnanotubes based on the 13C, 15N, and 11B NMR parameters and natural charge analysis. Weconsidered three types of zigzag nanotubes, ZZ-1, ZZ-2, and ZZ-3 (n, 0) with n = 8, 12, and 14. Theobtained results indicated the divisions of the electrostatic environments around C nuclei into a fewlayers, consist...
OBJECTIVE Human cadavers have been subjected to inverted drop, linear, and pendulum impacts to the top of the head, causing neck compression injury. The data are not comparable on the basis of impact velocity because of differing impact masses and test conditions. This study analyzed the published biomechanical data and used peak head velocity to merge the datasets. Correlations were determined...
This paper discusses meanings of intra-generational mobility when variables take values corresponding to either unordered or ordered categories. We propose concepts of maximum and minimum mobility, along with mobility-inducing transformations and related desirable properties. Then we axiomatically characterize indices of individual mobility and social mobility. Our first set of concepts, proper...
BACKGROUND The relation between physical access in emergency department (ED) and the time patients have to wait before being served is unknown. OBJECTIVES Our objective was to discover the associations between the physical access in ED and the time patients had to wait before receiving services. MATERIALS AND METHODS In this cross-sectional study, statistical society comprised two portions...
Timing belt transmission is a key subsystem of international combustion engines. Faults in such belt systems lead to power loss, increased emissions and, in case of failure, may even cause severe damage to the whole engine. Hitherto, the physical condition of the belt has been assessed manually, which is both inconvenient and inaccurate. It is well known that driving belts emit noise according ...
Heart disease is the main leading killer as well as a major cause of disability. Its timely detection and correct diagnosis plays a vital role in human life. In a limited period of time recalling the data from Doctor's unaided memory may lead to wrong judgments. While taking decisions, Doctor analyses the physical condition and test results of the patient. In the same way our system compares th...
Hospice patients at the end stages of life often suffer nausea and vomiting, distressing symptoms that are either side effects of medications or direct effects of the underlying disease state. Such symptoms can greatly diminish the hospice patient's quality of life. Effective pharmacotherapy is available, but in many cases traditional dosage forms are incompatible with the patient's physical co...
It has been observed that older high traffic motorways experience lower traffic growth than newer ones (ceteris paribus). This phenomenon is known as traffic maturity; however, it is not captured through traditional time-series long-term forecasts, due to constant elasticity to GDP these models assume. In this paper we argue that traffic maturity results from decreasing marginal utility of tran...
