Let $A$ be a $C^*$-algebra and $E$ be a left Hilbert $A$-module. In this paper we define a product on $E$ that making it into a Banach algebra and show that under the certain conditions $E$  is Arens regular. We also study the relationship between derivations of $A$ and $E$.

The notion of $k$-frames was recently introduced by Gu avruc ta in Hilbert  spaces to study atomic systems with respect to a bounded linear operator. A continuous frame is a family of vectors in a Hilbert space which allows reproductions of arbitrary elements by continuous super positions. In this manuscript, we construct a continuous $k$-frame, so called c$k$-frame along with an atomic system ...

A caracterização morfológica de uma espécie contribui para melhor identificação dos morfotipos, além subsidiar a produção alimentos, condimentos fitoterápicos e estéticos. No gênero Copaifera, dentre as diferentes espécies, Copaifera reticulata Ducke possui morfotipos que necessitam ser caracterizados serem aproveitados conservados. Nesse sentido, o trabalho teve por objetivo identificar caract...

I discuss recent progress in developing and exploiting connections between SAT algorithms and circuit lower bounds. The centrepiece of the article is Williams’ proof that NEXP * ACC0, which proceeds via a new algorithm for ACC0-SAT beating brute-force search. His result exploits a formal connection from non-trivial SAT algorithms to circuit lower bounds. I also discuss various connections in th...

The influence of carboxy methyl cellulose (CMC) and guargum-based coatings containing silver nanoparticles was studied on the postharvest storage stability of the kinnow mandarin (Citrus reticulata cv. Blanco) for a period of 120 days (85%-90% relative humidity) at 4 °C and 10 °C. Physicochemical and microbiological qualities were monitored after every 15 days of storage. Overall results reveal...

This study was carried out to find the effects of water-soluble vitamin C and fat-soluble E on growth both guppies, Poecilia reticulata (Peters, 1860), a kind live-bearing species. The control feed did not contain vitamins E, while other 15 experimental feeds were prepared by changing amount starch, without altering chemical structure, adding (100, 500, 1000 mg/kg) (75, 150, 300 in various leve...

The study was undertaken to envisage the effect of growth regulators on preharvest fruit drop and quality of Kinnow mandrin (Citrus reticulata Blanco). Various concentration of 2, 4-D, GA3 and NAA were applied during the last week of November, 2005 to check the impact of various treatments on preharvest fruit drop, yield and fruit quality. Exogenous application of growth regulators significantl...

Introduction: The aim was to assess the effects on lifestyle and lipid profile while fasting during holy month of Ramadan. Material and Methods: An interventional cohort study designed with 160 subjects who were fasting during Ramadan recruited from different mosques in Kermanshah. Data were collected in three stages at the beginning and at the end of Ramadan as well as one month following Rama...

Background & Aim: Policosanol is a component from main alcohol groups with long-chain that extracted from cane sugar. In the present research, the effect of policosanol was investigated on decrease of lipid metabolite levels in blood of hypercholesterolemia rats. Experimental: A number of 32 male Wistar rats race with average weight of 250 g was divided into four groups including negative cont...
