مقایسه تاثیر آروماتراپی با اسانس گل محمدی و حمام آبگرم پا بر اضطراب مرحله اول زایمان در زنان نخست زا
Introduction : Nulliparous women are very anxious in childbirth that this anxiety can reduce their chances for a normal delivery. The use of complementary therapies in reducing anxiety and more satisfaction from the birth is the need for further studies. This study compared the effects of aromatherapy with inhalation and foot bath with essential oils of damask rose and warm foot bath on anxie...
an experimental study of the phase inversion behavior of liquid-liquid dispersion has been conducted in a spray extraction column for systems of toluene / water, n-hexane/water, ccl4/water, toluene /water + glycerol (25 % wt), toluene + ccl4 (25 % wt) / water and toluene / acetic acid (5 % wt)/water. the effects of physical properties, mass transfer and column geometry on phase inversion have b...
introduction: suicide or para suicide is one of the known complications all around the world that unfortunately has had an increasing trend in recent decades. the aim of this study was to investigate the relationship between different phases of menstrual cycle and suicide attempts among suicidal women who referred to the poisoning ward of farschian hospital, hamedan, iran. materials and methods...
Reverse micellar systems are nanofluids with unique properties that make them attractive in high selectivity separation processes, especially for biological compounds. Understanding the phase behavior and thermodynamic properties of these nanosystems is the first step in process design. Separation of components by these nanosystems is performed upon contact of aqueous and reverse micellar phase...
in the present research, in contrast to the available papers, not only the superelasticity but also the shape memory effects are taken into account in determination of the impact responses. at the same time, in addition to modifying brinson’s model for the shape memory alloys (smas), to include new parameters and loading events, and hertz contact law, distributions of the sma phases are conside...
The members of Mycobacterium tuberculosis complex (MTBC) known as causative agents of human tuberculosis. Tuberculosis infection is one of the most important occupational risks for healthcare workers (HCWs) in most countries, such as Iran. In general, there are two types of tuberculosis, they include: latent infection and active TB. Latent tuberculosis infection (LTBI) means: a patient is infec...
in this paper a new method is introduced and investigated for removing the destabilizing effects of time-delay parameter in control loops. the concept of the method is taken from the knowledge concerning the dynamic behaviour of irrational transfer functions (ir-tf), which is discussed and investigated elswhere in frequency response domain and is explained briefly here. ir-tfs, which are well c...
