introduction tuberculosis is a contagious disease and a main cause of mortality in humans thus the world health organization has declared it as a global emergency. the aim of this study was to evaluate the prevalence of tuberculosis and involving factors in patients referring to the diagnosis laboratory of tuberculosis in ahvaz east health center. materials and methods the present study is a re...

tuberose (polianthes tuberosa l.) is one of the most important bulbous ornamental crops of tropical and subtropical areas. the objective of the present study was to determine the interaction effects of salinity and irrigation intervals on growth and flowering of two important commercial cultivars (‘mahallati’ and ‘dezfuli’) of tuberose (polianthes tuberosa l.). irrigation treatments consisted o...

the moist sample shrinks during drying and the non-uniformity shrinkage involves stresses in the body. the aim of the present work is simulating deformations and drying-induced stresses of carrot slice during a convective drying. the effect of shrinkage on the heat and mass transfer profiles were considered. non-constant physical and thermal properties were also incorporated in the model and th...

considering forage grass species, germination is one of the important stagesconcerning the growing stage that is often influenced by environmental stresses,particularly salinity and drought stresses. thus, this study aims to assess the effects ofsalinity and drought stresses on germination characteristics and seedling growth of desertwheatgrass, agropyron desertorum (fisch. ex link) schult. in ...

abu al-qasim khalaf ibn-e-abbas zahrawi(936-1013 a.d.), known as albucasis in west, was one of the greatest physicians in the islamic world. to many historians, he was considered as the father of modern surgery. his book, al-tasrif, e.g., written in 30 chapters, was, in fact, a medical encyclopedia of that era. it was used as one of the main references in medical academic centers for centuries....

from the historical and medical point of view, this paper purports to illustrate two motifs of immaculate conception in christian art. the first painting is an altarpiece of unknown author from the 17th or 18th century, known as our lady of conception in the church of st. antony the abbot in the city of rab on the island of the same name in croatia, and the other is a mural from 1490, mary’s an...

the relation between economy and medicine had a long history since ancient times. supplying (providing) health care and the required drugs and medical equipments were the main concerns of the human communities even when they were at rather primitive stages of civilization. later, in developed civilizations, trade was added to the concepts of medical economy. in this study, various economic acti...

allusion is one of the styles of covered expression, and is one of the basic elements of illustration in the history of vassāf. vāssaf al-hazrah tries to make the prose closer to the poetic prose and add to its effect by using expression elements and especially illusion. the lack of an edited copy of the history of vassāf and its obliged and created prose has been the reason that this work has ...

The present study aims to investigate the residual stresses and surface hardening in ground components caused by the coupled effect of thermo-plasticity and phase transformation. A feasible numerical method was developed to accommodate appropriately the phase transformation in a workpiece experiencing critical temperature variation during grinding. The change of material properties was modelled...

We use 1-D thermal history models and 3-D numerical experiments to study the impact of dynamic thermal disequilibrium and large temporal variations of normal and shear stresses on the initiation of plate tectonics. Previous models that explored plate tectonics initiation from a steady state, single plate mode of convection concluded that normal stresses govern the initiation of plate tectonics,...
