INTRODUCTION Bipolar disorder (BD) is a prevalent, comorbid, and impairing condition. Potential predictors of response to pharmacological treatment are object of continuous investigation in patients with BD. The present naturalistic study was aimed to assess clinical features and long-term response to mood stabilizers in a sample of bipolar subjects with different ages at onset. METHODS The s...
in this paper, we introduce the concepts of right, left and product stabilizers on hoops and study some properties and the relation between them. and we try to find that how they can be equal and investigate that under what condition they can be filter, implicative filter, fantastic and positive implicative filter. also, we prove that right and product stabilizers are filters and if they are ...
This narrative review describes recent developments in the use of technology for utilizing the self-monitoring of mood, provides some relevant background, and suggests some promising directions. Subjective experience of mood is one of the valuable sources of information about the state of an integrated mind/brain system. During the past century, psychiatry and psychology moved away from subject...
aflatoxins are a group of fungal toxic metabolites, which are contaminated certain food commodities. elisa is one of the sensitive methods for detection of aflatoxins. preparation and stabilizing of a proper conjugated tracer for detection of aflatoxins is probably the main step for designing an elisa method. in current study, different stabilizers were applied to stabilize a newly prepared con...
In [7] a characterization of transitive permutation groups having a non-self-paired suborbit of length 2 (with respect to which the corresponding orbital graph is connected) was obtained in terms of their point stabilizers. As a consequence, elementary abelian groups were proved to be the only possible abelian point stabilizers arising from such actions, and D8 was shown to be the only nonabeli...
Propellants containing nitrate esters need stabilizers to avoid early decomposition or even explosion during storage. Newly prepared malonanilides M1-M5 were tested in stabilizing double-base propellants (DBPs). Their stabilization was compared with the effect of classical stabilizer N,N'-diethyldiphenyl urea (C1) using both practical thermal stability tests (qualitative and quantitative tests)...
Autocatalysis decomposition of single and double-base propellants is caused to production of nitrogen oxides radicals. Produced radicals, meantime reducing the inner energy of propellant, increased the decomposition process. To restriction of this process, some materials were added to propellant formulation as a stabilizer. Common stabilizers are toxic therefore, decreasing the toxicity and enh...
Quantum chemical investigations of the action of hindered phenol radical stabilizers in lubricant degradation chemistry have been completed. We are currently developing the first mechanistic models of lubricant degradation with the aim of including the chemistry of additives such as radical stabilizers that are found in commercial lubricant formulations. A key component of development of these ...
This paper studies the theory and modeling manner of solid oxide fuel cell (SOFC) into power network and its effect on small signal stability. The paper demonstrates the fundamental module, mathematical analysis and small signal modeling of the SOFC connected to single machine infinite bus (SMIB) system. The basic contribution of the study is to attenuate the low frequency oscillations by optim...
