rivers and runoff have always been of interest to human beings. in order to make use of the proper water resources, human societies, industrial and agricultural centers, etc. have usually been established near rivers. as the time goes on, these societies developed, and therefore water resources were extracted more and more. consequently, conditions of water quality of the rivers experienced rap...
in this thesis, we consider a mathematical model of cancer with completely unknown parameters. we study the stability of critical points which are biologically admissible. then we consider a control on the system and introduce situations at which solutions are attracted to critical points and so the cancer disease has auto healing. the lyapunov stability method is used for estimating the un...
BACKGROUND Stress on the bone surrounding dental micro-implants affects implant success. PURPOSE To compare the stress on the bone surrounding a micro-implant after application of a single force (SF) of 200 g or a composite force (CF) of 200 g and 6 N.mm torque. MATERIALS AND METHODS Finite element models were developed for micro-implant diameters of 1.2, 1.6, and 2.0 mm, and lengths of 6, ...
The H4IIE cell bioassay has proven utility as a screening tool for planar halogenated hydrocarbons (PHHs) and structurally similar chemicals accumulated in organisms from the wild. This bioassay has additional applications in hazard assessment of PHH exposed populations. In this review, the toxicological principles, current protocols, performance criteria, and field applications for the assay a...
The impact of a confinement dairy operation (>2000 head) using best management practices for land application of animal wastes, on estrogenic activity (E-Screen), estrogens, and nutrients of associated surface waters and tile drain runoff were evaluated. Farm tile drain and creek samples were collected from the drainage region: above and below a municipal wastewater treatment plant located upst...
since its introduction in 1959, translation quality assessment (tqa) has been among the most addressed research topics in translation studies. during recent years, there has been a crucial increase on the study of tqa. various methods have come on scene. although these methods are based on scientific theories, most of them have remained at the level of theory. juliane house’s model is among tho...
OBJECTIVES This study draws from the resource depletion and conservation theories to develop a process model of informal caregiving. The model includes the burnout as a key mediator of the relationship between benefit/threat appraisals and critical outcomes including perceived physical health, depression and life satisfaction. METHODS A self-report questionnaire was utilized to collect releva...
We consider in the paper some consequences of the Nonsymmetric Kaluza–Klein (Jordan–Thiry) Theory with spontaneous symmetry breaking connecting to the existence of the warp factor. We develop in the paper some applications and consequences of the Nonsymmetric Kaluza–Klein (Jordan–Thiry) Theory extensively presented in the first point of Ref. [1]. We refer for all the details to Ref. [1], especi...
Coastal environments are exposed to numerous pressures that potentially affect marine soft bottom faunas. Among these pressures, organic matter enrichment is very frequent. Several indices based on living (Rose Bengal-stained) foraminiferal communities have recently been developed assess the induced impact and determine environmental quality of environments. Here, we use an open waters Mediterr...
