Balancing Asymmetric Dark Matter with Baryon Asymmetry and Dilution of Frozen Dark Matter by Sphaleron Transition

In this paper, we study the effect of electroweak sphaleron transition and electroweak phase transition (EWPT) in balancing the baryon excess and the excess stable quarks of the 4th generation. Sphaleron transitions between baryons, leptons and the 4th family of leptons and quarks establish a definite relationship between the value and sign of the 4th family excess and baryon asymmetry. This relationship provides an excess of stable U¯ antiquarks, forming dark atoms—the bound state of (U¯U¯U¯) the anti-quark cluster and primordial helium nucleus. If EWPT is of the second order and the mass of U quark is about 3.5 TeV, then dark atoms can explain the observed dark matter density. In passing by, we show the small, yet negligible dilution in the pre-existing dark matter density, due to the sphaleron transition.

Кости животных из позднесарматских погребений курганной группы «Кермен Толга»

Introduction. The article introduces results of studies of animal bones excavated by the archaeological expedition of Kalmyk Research Institute of History, Philology and Economics (with E. V. Tsutskin as leading scientist) from Late Sarmatian burials within the Kermen Tolga Mound Group in the Sarpa Lowlands in 1979. Goals. The paper provides detailed descriptions of the animal bone remains, identifies their species composition, enumerates and compares the samples. Results. The study shows all the investigated Late Sarmatian burials of the Kermen Tolga Mound Group contained bone remains of only one domesticated animal — sheep (Ovis aries). Conclusions. The analysis of bone materials described in the field summary report and stored at Kalmyk Scientific Center of the RAS reveals that seven of the ten female burials excavated were containing bones of the back right leg, while in four of the six male burials there were found bones of the back left leg. The conclusions are preliminary but there is a definite relationship between the gender of each single buried individual and the side of animal’s body used therein. This may indicate the earlier unnoticed element of Late Sarmatian funeral rites.

New Cladosporium Species from Normal and Galled Flowers of Lamiaceae

A series of isolates of Cladosporium spp. were recovered in the course of a cooperative study on galls formed by midges of the genus Asphondylia (Diptera, Cecidomyidae) on several species of Lamiaceae. The finding of these fungi in both normal and galled flowers was taken as an indication that they do not have a definite relationship with the midges. Moreover, identification based on DNA sequencing showed that these isolates are taxonomically heterogeneous and belong to several species which are classified in two different species complexes. Two new species, Cladosporium polonicum and Cladosporium neapolitanum, were characterized within the Cladosporium cladosporioides species complex based on strains from Poland and Italy, respectively. Evidence concerning the possible existence of additional taxa within the collective species C. cladosporioides and C. pseudocladosporioides is discussed.

About excretion of uric acid

In contrast to the data of Steudel'ya M. Ya. Kalf-Calif (Doctor. Delo, 1925, No. 21) in his experiments found that there is no definite relationship between the intensity of putrefactive fermentation processes in the intestine and the release of uric acid.

‘Politeness Markers’ Revisited - A Contrastive Pragmatic Perspective

This paper revisits the concept of ‘politeness marker’, by proposing the bottom-up and corpus-based model of ‘ritual frame indicating expressions’ (RFIEs). Our central argument is that, in certain linguacultures, the relationship between ‘politeness markers’ and politeness itself is significantly stronger than in others. Therefore, any theory which argues that there is a definite relationship between form and politeness - or totally rejects this relationship - is potentially problematic if it does not take a contrastive pragmatic perspective, simply because this relationship is subject to significant linguacultural variation. The contrastive pragmatic study of RFIEs also helps us to determine the relationship between forms and speech acts and, indirectly, politeness. As a case study, we examine in this paper one-word and more complex expressions which are commonly associated with the speech acts of request and apology, drawn from the typologically distant Chinese and English linguacultures.

Analyzing the Relationship between Cohort and Case-Control Study Results Based on Model for Multiple Pathogenic Factors

Objective. Although the relative risk from a prospective cohort study is numerically approximate to the odds ratio from a case-control study for a low-probability event, a definite relationship between case-control and cohort studies cannot be confirmed. In this study, we established a different model to determine the relationship between case-control and cohort studies. Methods. Two analysis models (the cross-sectional model and multiple pathogenic factor model) were established. Incidences in both the exposure group and the nonexposure group in a cohort study were compared with the frequency of the observed factor in each group (diseased and nondiseased) in a case-control study. Results. The relationship between the results of a case-control study and a cohort study is as follows: Pe=Pd∗m/Pc∗1−m+Pd∗m; Pn=m∗1−Pd/1−Pc∗1−m−Pd∗m, where Pe and Pn represent the incidence in the exposed group and nonexposed group, respectively, from the cohort study, while Pd and Pc represent the observed frequencies in the disease group and the control group, respectively, for the case-control study; finally, m represents the incidence in the total population. Conclusions. There is a definite relationship between the results of case-control and cohort studies assessing the same exposure. The outcomes of case-control studies can be translated into cohort study data.

Comment on ‘Cell phone use and ill health: is there a definite relationship?’

Prof Gboyega A Ogunbanjo, in his editorial entitled ‘Cell phone use and ill health: is there a definite relationship?’, published in South African Family Practice, has addressed the possible link between mobile phone use and adverse health effects such as cancer. He has also discussed the challenging issue of electromagnetic hypersensitivity (EHS). Although his editorial has remarkable strengths, this paper needs some clarifications. The main concerns regarding the evidence presented in this paper about possible association of mobile phone use with cancer are discussed. In this light, recent evidence that supports a possible link as well as the shortcomings of the reports claiming no association between exposure to radiofrequency radiation and cancer are presented.

CONDICIONES ACTUALES DEL FINANCIAMIENTO DE LAS PYMES COSTARRICENSES. (Current financing conditions for costa rican SME companies)

<p>Uno de los temas indagados en el Segundo estudio nacional realizado por el Observatorio Costarricense de Mipymes durante el 2011 corresponde al financiamiento de las micros, pequeñas y medianas empresas costarricenses. Se consultaron las fuentes de financiamiento más utilizadas, la presentación de solicitudes de crédito durante los últimos cinco años, la utilización que en general hacen estas empresas de los diferentes medios de financiamiento y sus requerimientos actuales. De forma similar a lo que ocurre en otros países, los fondos propios constituyen la principal opción para estas empresas. Por ello, en este trabajo han sido analizadas las condiciones que propician la autofinanciación o el uso de otras opciones. Por medio del análisis estadístico de la información recopilada en la encuesta, se comprueba que algunas variables relativas a la gestión empresarial, tales como la fuente de financiamiento inicial, la experiencia del (de la) empresario(a) y la prioridad que dan al manejo de aspectos financieros, presentan una asociación significativa con las estrategias de financiamiento en las mipymes costarricenses.</p><p><strong>ABSTRACT</strong></p><p>Financing was one of the areas investigated in the Second National Survey of micro, small and medium sized Costa Rican companies during 2011. The most used financing sources, credit applications during the last five years, end use of this credit, and current credit requirements in various financing institutions were investigated. Similar to other countries, own funding was the main option for these companies. Thus, this work examines the conditions that facilitate the use of self financing or other options available. Through statistic analysis of the information collected, variables like initial funding source, previous experience of the entrepreneur and priority given to financial management were shown to present a definite relationship to financing strategies for Costa Rican SMEs.</p>

IgG4-Related Disease Is Not Associated with Antibody to the Phospholipase A2 Receptor

Patients with IgG4-related disease (IgG4-RD) share histopathological characteristics that are similar across affected organs. The finding of infiltration with IgG4+ plasma cells in the proper clinical and histopathological contexts connects a large number of clinical entities that were viewed previously as separate conditions. The renal involvement in IgG4-RD is usually characterized by tubulointerstitial nephritis, but membranous nephropathy has also been reported to be one of the renal complications of IgG4-RD. The recent discovery that a high proportion of patients with idiopathic membranous nephropathy (IMN) have IgG4 autoantibodies to the M-type phospholipase A2 receptor (PLA2R) in the circulation and glomerular immune deposits, together with the profound IgG4 hypergammaglobulinemia and occasional reports of membranous nephropathy in IgG4-RD, raised the question of a common antigen. To assess the presence of anti-PLA2R antibody in patients with IgG4-RD, we screened sera from 28 IgG4-RD patients by immunoblot. None of the patients in this cohort had detectable circulating anti-PLA2R antibodies. This study suggests that despite some clinical and serological overlaps between IgG4-RD and IMN,anti-PLA2R antibodies do not play a role in the pathogenesis of IgG4-RD. Additional studies of IgG4-RD with evidence of membranous nephropathy are important to exclude any definite relationship.
