In cooperative games, players have a possibility to form different coalitions. This leads the questions about ways motivate all collaborate, i.e. so-called grand coalition. One of such is captured by concept nucleolus, which dates back Babylonian Talmud. Weighted voting games class that are often used model decision making processes in parliaments. this paper, we provide an algorithm for comput...

Chromosomes of three chalcid wasp species from Brazil, Palmistichus elaeisis Delvare et LaSalle, 1993, Trichospilus diatraeae Cherian et Margabandhu, 1942 (both belonging to the family Eulophidae) and Trichogramma pretiosum Riley, 1879 (Trichogrammatidae), were studied using chromosome morphometrics and base-specific fluorochrome staining. The present study confirmed that these species respecti...

Here, we reported two cases of nonspecific interstitial pneumonia overlap organizing pneumonia (NSIP/OP) with lung-dominant connective tissue disease (LD-ILD). The first case is a patient with hands of chapped skin, right-sided pleuritic chest discomfort, weakness, positive ANA and antibodies to Ro/SS-A (+++) and Ro-52 (++). In the second case, there were Reynaud's disease, and nucleolus-ANA in...

The activation of the nucleolus of primary root cells of Sinapis alba embryos during the first 72 h of germination was monitored by autoradiographic, ultrastructural and microstereological methods. Autoradiographs showed that within 48 h, the nucleolus progressively resumed the capacity to synthesize pre-rRNA molecules at a high rate. In quiescent embryos the nucleolus was small, compact and co...

The interphase nucleolus in root meristematic cells of Allium cepa may be divided into four regions, three of which are always present: the fibrillar, granular and lacunar regions, while the fourth or vacuolar region may be missing. The sites of protein synthesis in nucleoli were investigated by means of light and electron-microscope radioautography after a 5-min immersion of the roots in a sol...

P-element transformants of a single rRNA gene (rDNA) were used to investigate the relationship between the organization of the nucleolus organizer (NO) and rDNA function in Drosophila melanogaster. In situ hybridization to rRNA in polytene nuclei of salivary glands demonstrated that an rRNA gene can be transcribed at a high rate when inserted into chromosomal sites other than the NO. Structures...
