In this paper, in addition to some elementary facts about the ultra-groups, which their structure based on the properties of the transversal of a subgroup of a group, we focus on the relation between a group and an ultra-group. It is verified that every group is an ultra-group, but the converse is not true generally. We present the conditions under which, for every normal subultra-group of an u...

ultra-endurance mountain running has become extremely popular in recent years, and the energy cost is one of the factors that influence the final performance. the aim of this study was to determine if the energy cost of uphill running (uphill cr) can be calculated from level cr (energy cost of running in mlo2.kg-1.mn-1) in a heterogeneous group of mountain ultra-endurance runners using the di p...

background : one of the most prevalent side effects of hemodialysis is intradialytic hypotension and its symptoms. using sodium profiles 3 and ultra filtration profile 3 and cold dialysate are the ways to overcome this problem. since none of these methods could control this complication lonely, this study was done to investigate the effect of combination of two methods on intradialytic hypotens...

The aim of this study was to determine how an ultra-short anatomic uncemented stem vs a diaphyseal filling five-eighths porous coated uncemented femoral stem (conventional stem) affects the survival of primary total hip arthroplasties in octogenarians. The current study consisted of 52 patients (55 hips) in the ultra-short stem group (mean age, 85.5±5.3 years) and 61 patients (72 hips) in the d...

abstract background: inadequate dialysis is one of the main causes of mortality of the patients undergoing hemodialysis. the methods that lead to improvement of dialysis adequacy in these patients are of great importance due to them causing an improvement of quality of life. as numerous factors can play a role in improvement of dialysis adequacy, the present study aimed to investigate the level...

Let Ȳ be a n-dimensional curve. Is it possible to compute topoi? We show that g̃ = 2. It would be interesting to apply the techniques of [20] to covariant topoi. This reduces the results of [20] to an approximation argument.

BACKGROUND Exercise-associated hyponatremia (EAH), rhabdomyolysis and renal failure appear to be a unique problem in ultra-endurance racers. METHODS We investigated the combined occurrence of EAH and rhabdomyolysis in seven different ultra-endurance races and disciplines (i.e. multi-stage mountain biking, 24-h mountain biking, 24-h ultra-running and 100-km ultra-running). RESULTS Two (15.4%...

OBJECTIVE To investigate how consumption of ultra-processed foods has changed in Sweden in relation to obesity. DESIGN Nationwide ecological analysis of changes in processed foods along with corresponding changes in obesity. Trends in per capita food consumption during 1960-2010 were investigated using data from the Swedish Board of Agriculture. Food items were classified as group 1 (unproces...

OBJECTIVE To investigate consumption of ultra-processed products in Canada and to assess their association with dietary quality. DESIGN Application of a classification of foodstuffs based on the nature, extent and purpose of food processing to data from a national household food budget survey. Foods are classified as unprocessed/minimally processed foods (Group 1), processed culinary ingredie...
