introduction: groundwater is the largest resource of water supplement and shortages of surface water supplies in drought conditions that requires an increase in groundwater discharge. groundwater flow dependson the subsurface properties such as hydraulic gradient (water table gradient or head loss in artesian condition) and hydrodynamic coefficients. the flow treatment is analyzed with an accur...

Stereoelectronic effects is a bridge between structure and reactivity [1]. Anomeric effect plays an important role in the domain of stereoelectronic interaction and can be used for description of several unusual phenomena. Intramolecular negative hyperconjugation is also known as anomeric effect [2]. In anomeric effect, both donor (lone pairs) and acceptor groups (electronegative elements) coex...

  One of the dimensions of human life is its socio-political aspect. In this regard an important issue is the view of Islam towards the formation of government at the age of occultation. Referring to certain traditions, some believe that any kind of uprising and revolution prior to the emergence of Hazrat Qaem (Aj.) will be unlawful and add, “Any flag which is raised prior to the emergenc...

An uncontrolled immune system threatens human health as much as a defective one. Autoimmune diseases, such as type 1 diabetes (T1D), result from destruction of healthy tissues by a rogue immune system. Much of the selfpolicing of the immune system can be attributed to one subset of T cells called regulatory T cells (Tregs) (1). Patients with congenital defects in Tregs develop fatal multiorgan ...

Szkic prezentuje najciekawsze/najgłośniejsze polskie książki prozatorskie i poetyckie opublikowane w 2020 roku celu swoistego podsumowania tego, co działo się na polskim rynku wydawniczym minionym roku. Autorka próbuje odpowiedzieć pytanie, czy pandemia koronawirusa jakiś sposób wpłynęła pisarki/pisarzy, poetów/poetki wydawców. Jej celem jest sprawdzenie, jakiego typu literaturę piękną najchętn...

Two methods for determining dexterity of manipulator arms are presented. A numerical method is illustrated for determining all possible orientations of the end-effector of an open kinematic chain based upon a row-rank deficiency of the sub-Jacobian of the kinematic constraint equations. This numerical method has been adapted from a theory for determining the accessible output set for planar and...

One of the decisive factors in obtaining the desired properties in coatings is their complete curing, which necessitates the study of kinetics of curing. In recent years, many studies have been conducted on the use of polyhedral oligomeric silsesquioxane (POSS) in coatings. Creating functional groups on POSS and using it in formulation can create new or improve the properties of coatings. I...

Background: Due to unpredictability of events in psychiatry environment and replacement of routine clinical experiences with some assignments such as therapeutic communication with patients, clinical training in such environments has been associated with many problems which require continuous review and evaluation.  The purpose of the present research was to determine the effect of applying por...
