Can the Fundamental Theory Of Everything be Renormalizable?
Some considerations showing that renormalizable theories with consistent
perturbative theries can not be nonperturbatively finite (in terms of bare
parameters) are provided. Accordingly any fundamental unified theory has to be
either non renormalizable or order by order finite.Comment: 3 pages (LaTEX file
Perturbative Approach For Non Renormalizable Theories
Renormalization procedure is generalized to be applicable for non
renormalizable theories. It is shown that introduction of an extra expansion
parameter allows to get rid of divergences and express physical quantities as
series of finite number of interdependent expansion parameters. Suggested
method is applied to quantum (Einstein's) gravity.Comment: 14 pages (LaTEX file
Influence of zeolıte on red soıls ın southwestern georgıa
Doğal kayaların, yani Zeolit arttırıcı dozların etkisi, çay bitkileriyle kaplanmış olan kızıltoprak arazinin kimyasal verileri: pH; Asitliği; Humus; Nitrojen ve temel gıda elementlerinin içeriği üzerinde araştırma yapılmıştır. Eksperimental olarak ortaya çıkmıştır ki Lançkhuti Kasabası Shukhuti Köyünde ortaya çıkan Filifsitik Zeolitler kızıltoprak arazilerinin verimliliğinin seviyesini önemli derecede güçleştirmektedir. Bununla birlikte belirtilen bu zeolitler tarım-ziraat alanlarında (Çay) verilen mineral gübrelerinin üzün süreli etkisi ve efektisini yükseltmektedirInfluences of zeolite addition into pH, acidity, organic matter, nitrogen and main nutrients properties of tea cultivated soils were investigated in this study. It has been determined that Filifsidik zeolites that found in Shukhuti village of Lançkhuti town lowered the fertility of soils in the area. However, zeolite use in cultivated areas, especially tea plantation areas has increased the effectiveness of applied fertilizers
On the regularization scheme and gauge choice ambiguities in topologically massive gauge theories
It is demonstrated that in the (2+1)-dimensional topologically massive gauge
theories an agreement of the Pauli-Villars regularization scheme with the other
schemes can be achieved by employing pairs of auxiliary fermions with the
opposite sign masses. This approach does not introduce additional violation of
discrete (P and T) symmetries. Although it breaks the local gauge symmetry only
in the regulator fields' sector, its trace disappears completely after removing
the regularization as a result of superrenormalizability of the model. It is
shown also that analogous extension of the Pauli-Villars regularization in the
vector particle sector can be used to agree the arbitrary covariant gauge
results with the Landau ones. The source of ambiguities in the covariant gauges
is studied in detail. It is demonstrated that in gauges that are softer in the
infrared region (e.g. Coulomb or axial) nonphysical ambiguities inherent to the
covariant gauges do not arise.Comment: Latex, 13 pages. Replaced mainly to change preprint references to
