OBJECTIVE This report presents the sociodemographic characteristics, functional dependencies in the activities of daily living (ADL) and instrumental activities of daily living (IADL), dental status, primary admission diagnosis, types of services used, and source of payment of elderly nursing home residents. METHODS The data used for this report are from the National Center for Health Statist...
The present research studied the electronic transport of an ideal infinite ladder nanostructure in the presence/absence of network defects by using Green’s function method at the tight-binding approximation. The network defects can be simulated by considering a finite ladder which is connected via two contacts to two similar infinite ladders. The results showed that the hopping energy of rungs...
Two-dimensional (2-D) device simulation is used to investigate the tunneling current of metal ultra-thin-oxide silicon tunneling diodes with different oxide roughness. With the conformal nature of ultrathin oxide, the tunneling current density is simulated in both direct tunneling and Fowler–Nordheim (FN) tunneling regimes with different oxide roughness. The results show that oxide roughness dr...
A theoretical study of resonant tunneling in multilayered GaAlAs/GaAs structures are presented. The spectrum of resonant energies and its dependence on the barrier structure are analyzed from calculated profiles of barrier transparency versus energy, and from current voltage characteristics computed at selected temperatures and Fermi levels. The present formalism is based on the effective mas...
Understanding of the dynamic process of laser-induced ultrafast electron tunneling is still very limited. It has been thought that the photo-catalytic reaction of adsorbents on the surface is either dependent on the number of resultant electron-hole pairs where excess energy is lost to the lattice through coupling with phonon modes, or dependent on irradiation photon wavelength. We used UV (355...
dear editor, implementing health and family planning programs is the most effective way for birth control. intrauterine device (iud) is an effective long-acting contraceptive mean. 1 considering little side effects and good compatibility of iud to physiologic hormonal alterations occurring during breast feeding, the device is an acceptable contraceptive mean in nursing mothers. 2 in spite of ...
AIM The present study designed to evaluate the effect of different feeding systems on the behavior of local Rohilkhandi kids. MATERIALS AND METHODS A total of 21 growing goats (local goat of Rohilkhand region), weighing around 7-11 kg and aging 4-5 months, were used. These animals were kept in three groups. Group I was fed un-chopped green fodder in circular feeder (newly designed). Group II ...
Background & Aims: The purpose of the present study was to compare feeding problems, infant eating behavior, and feeding styles between infants with and without feeding problems according to their mothers’ narratives. Methods: In this casual-comparative study, 50 mother-infant dyads were selected using convenient sampling. The infants’ ages ranged between 6 to...
