On the Hilbert 22-class field tower of some abelian 22-extensions over the field of rational numbers

summary:It is well known by results of Golod and Shafarevich that the Hilbert $2$-class field tower of any real quadratic number field, in which the discriminant is not a sum of two squares and divisible by eight primes, is infinite. The aim of this article is to extend this result to any real abelian $2$-extension over the field of rational numbers. So using genus theory, units of biquadratic number fields and norm residue symbol, we prove that for every real abelian $2$-extension over $\mathbb Q$ in which eight primes ramify and one of theses primes $\equiv -1\pmod 4$, the Hilbert $2$-class field tower is infinite

Participatory management opportunity for optimizing in agricultural extension education

AbstractThis study refines the participatory management (PM) in agricultural extension education (AEE) by adopting a multidimensional approach. PM is a process where extension agent (EA) tries to provide a good situation for AEE and share significant degree of power with their farmers. The data were obtained from samples of 290 Iranian farmers in Torbat Heydarieh, Iran. Methodology was descriptive and correlation. There was directly and a statically significant relation between all of components of PM regarding in effective AEE. The PM is a panacea for improving the AEE. Findings confirm the application of PM for achieving suitable strategy to AEE

Investigating the Consumer Attitude toward Green Marketing

Recently climate change issues have come to the forefront. Climate change is a global challenge. It is a threat to social and economic stability and sustainable human existence. There is no doubt that climate change affects the fundamental requirement for health – clean air, safe drinking water, sufficient green food and secured shelter. Many measures have to be planned for and taken into account when adapting to climate changes .As a third world country Bangladesh can place a good phenomena in climate change through adapting consumer attitude towards green marketing . According to the study, consumers are very much sensitive in a few factors. These factors are consumer’s loyalty about green product, Global warming and environmental safety, quality of product, concern about extra price and Luxury and Environmental awareness. Both descriptive and inferential statistics were used in analyzing data. And we distribute 120 questionnaires among the people. And for analyses the data, we use correlation and regression, according to that all of the hypotheses accepted. Keywords: Green product, Green consumer, Corporate Social responsibility, Green marketing

Hemi-ESES associated with agenesis of the corpus callosum and normal cognition.

Corpus callosum plays the important role in bilateral synchronous expression of focal discharges of ESES. Sparing dominant hemisphere form continuous spike and slow waves during sleep accounts for normal cognitive scores. Early detection and treatment of ESES have a great impact on cognitive and language scores and final prognosis

ON GENERALIZED RELATIVE COMMUTATIVITY DEGREE OF FINITE MOUFANG LOOP

For a given element $g$ of a finite group $G$, the probablility that the commutator of randomly choosen pair elements in $G$ equals $g$ is the relative commutativity degree of $g$.  In this paper we are interested in studying the relative commutativity degree of the Dihedral group of order $2n$ and the Quaternion group of order $2^{n}$ for any $n\geq 3$ and we examine the relative commutativity degree of infinite class of the Moufang Loops of Chein type, $M(G,2)$

Direct growth of ternary copper nickel cobalt oxide nanowires as binder-free electrode on carbon cloth for nonenzymatic glucose sensing

A new binder free electrode based on ternary copper nickel cobalt oxide nanowires grown on the carbon cloth (CuNiCoO4 NWs@ carbon cloth) was prepared and characterized by field emission scanning electron microscopy (FE-SEM), x-ray diffraction (XRD), Energy-dispersive X-ray spectroscopy (EDX), and cyclic voltammetry (CV). The prepared electrocatalyst was directly used for electrochemical sensing of glucose without using enzyme. The effect of different parameters such as potential scan rate, switching potential, and glucose concentration on the electrochemical oxidation of glucose was investigated. The results showed that such an electrode presents excellent catalytic activity toward the oxidation of glucose in aqueous alkaline solution. Under optimum conditions, the potential application of the electrode was evaluated by applying it to the analytical determination of glucose concentration. The results revealed that the electrocatalytic current increased linearly with the glucose concentration in the range from 0.02 to 1.4 mM with a low detection limit of 6.5 μM and good sensitivity of as high as 1782 μA mM−1 cm−2 . Selectivity investigations demonstrate that the CuNiCoO4 NWs@CC electrode could be used for selective detection of glucose in the presence of interfering species. Real sample analysis shows reasonable RSD values implying negligible matrix effect in determination of glucose in human serum samples
