In [4] it was conjectured that for all unit vectors u1, · · · , ud in Rd, X (u1, · · · , ud) := sup x∈Rd, |x|2=d d ∏ i=1 〈x, ui〉 ≥ 1 with equality occurring iff u1, · · · , ud are orthonormal. We relate this to a conjecture about solutions of Ay = y−1, where A = (〈ui, uj〉), and show that if the conjecture fails then the u1, · · · , ud minimizing X must be linearly dependent. We also show X (u1,...

In [C. Benítez, Y. Sarantopoulos, A. Tonge, Lower bounds for norms of products of polynomials, Math. Proc. Cambridge Philos. Soc. 124 (3) (1998) 395–408] it was conjectured that for all unit vectors u1, . . . , ud in Rd , X (u1, . . . , ud ) := sup x∈Rd , |x|2=d d ∏ i=1 〈x,ui〉 1 with equality occurring iff u1, . . . , ud are orthonormal. We relate this to a conjecture about solutions of Ay = y−...
Sitele moleculare din carbon (CMS) sunt adsorbanţi carbonici de mare importanţă. Această lucrare prezintă rezultatele studiului privind prepararea sitelor moleculare din carbon şi modificarea structurii porilor. Proprietăţile sitelor moleculare ale varietăţilor de cărbuni au fost studiate prin măsurarea capacităţii de adsorbţie dinamică a dioxidului de carbon utilizând sistemul PSA ( adsorbţia ...
We present new estimates of emissions of nitrous oxide (N2O) from rivers and estuaries, using the NEWS-DIN model. NEWS-DIN is a model of the global transport of dissolved inorganic nitrogen (DIN) by rivers to coastal waters (Dumont et al. forthcoming). It calculates DIN export rates as a function of watershed characteristics, including human influences. We used the calculated DIN export rates b...
Previous research concerning the effects of television on children has tended to focus upon the learning of social behaviors and attitudes (2,4,5). That children’s age-related cognitive limitations would affect their perceptions of television programming and presumably mediate learning seems evident, yet this area is only now coming under frequent discussion. The purpose of this study was to ex...
Environmental cues transduced by an endocrine network converge on Caenorhabditis elegans nuclear receptor DAF-12 to mediate arrest at dauer diapause or continuous larval development. In adults, DAF-12 selects long-lived or short-lived modes. How these organismal choices are molecularly specified is unknown. Here we show that coregulator DIN-1 and DAF-12 physically and genetically interact to in...
BACKGROUND Urinary density (UD) has been routinely used for decades as a surrogate marker for urine osmolality (Uosm). We asked if UD can accurately estimate Uosm both in healthy subjects and in different clinical scenarios of kidney disease. METHODS UD was assessed by refractometry. Uosm was measured by freezing point depression in spot urines obtained from healthy volunteers (N = 97) and in...
The study of the source of the thoughts of great intellectualist and poets, and the extent to which they are adapted and manipulated in the works of our predecessors, helps us to better understanding and further the fundamentals of their thoughts. Jami is one of the famous poets of Iran ninth-century who has devoted numerous works to his poetry and prose. In this study, we have studied Haft Ovr...
In our study, we aimed to investigate the acute toxicity and analgesic effect of Urtica dioica L fixed oil (UD) in mice, and its anti-inflammatory effect in rats. The acute toxicity of UD was tested for the increasing doses between 0.2 and 12.8 mL/kg. The anti-inflammatory effect was studied in carrageenan induced tissue inflammation model and the effect of two different doses of UD was compare...
