A matrix $A\in M_n(R)$ is $e$-clean provided there exists an idempotent $E\in M_n(R)$ such that $A-E\in \mathop{\rm GL}_n(R)$ and $\det E=e$. We get a general criterion of $e$-cleanness for the matrix $[[a_1,a_2,\cdots ,a_{n+1}]]$. Under the $n$-stable range condition, it is shown that $[[a_1,a_2,\cdots ,a_{n+1}]]$ is $0$-clean iff $(a_1,a_2,\cdots ,a_{n+1})=1$. As an application, we prove that the $0$-cleanness and unit-regularity for such $n\times n$ matrix over a Dedekind domain coincide for all $n\geq 3$. The analogous for $(s,2)$ property is also obtained.
Using results of extensive research in central and company archives, the author studies the cleansing of industrial plants from collaborationists and so-called anti-social elements in Czechoslovakia in 1945. He describes it as a standard-setting process during which the form of a new revolutionary value system and guilt criteria in relation to the occupation past arising therefrom were negotiated and established in practice in factories and plants. Both escalated nationalism and social egalitarianism, sometimes developing into class antagonism, found their use in it. In addition to acts prosecuted under offi cial legislation, the cleansing process incorporated various minor confl icts of employees during the occupation, in particular disputes between subordinates and superiors. For this reason, mainly top-ranking white collars, human resource offi cers, rate setters, and shop foremen were removed from their positions. The articulation of guilt of the above group also worked as an absolution of others, particularly rank-and-fi le workers and white collars, atthe symbolic and psychological level. The selected guilt criteria were subsequently becoming a part of the legitimization pattern of the ongoing revolution. The study illustrates how company councils, acting through investigation commissions which, nevertheless, had to create their own legal rules as they had no position or status defi ned in offi cial legislation, were trying, since mid-May 1945, to regulate, formalize, and unify initial spontaneous actions of employees. However, the legal uncertainty in factories led to a decline of respect to superiors, deterioration of working morale, and devaluation of expertise. In mid-July 1945, organs of the Revolutionary Trade Union Movement intervened into the cleansing process, as they were interested in improving the performance of the nationalized industry. Appeal chambers were established at regional trade union councils as second-instance bodies deciding disputes submitted by industrial plants. In doing so, they were demanding a higher quality of submitted legal documents and supporting assigning the individuals affected by the cleansing to adequate working positions in the production process. In October 1945, results of the company cleansing process were incorporated, under the pressure of trade unions, into offi cial legislation under the so-called Small Retribution Decree. The resulting legal framework was thus an apparent compromise between pre-war legal conventions and moral criteria established during the May 1945 revolution. and Přeložil Jiří Mareš
Clear cell odontogenic carcinoma (CCOC) is a rare odontogenic tumor associated with aggressive clinical behavior, metastasis and low survival. We report a case of CCOC affecting the maxilla of 62 year-old woman. It was first described as a clinicopathological entity in 1985 and to date only 67 cases were described in the English literature. We are understanding of the behavior of this carcinomas was depend on limited case reports. For these reason we found important to report this case of CCOC in the maxilla., Zahide Mine Yazici, Ozgur Mete, Zubeyde Elmalı, İbrahim Sayin, Rasim Yilmazer, Fatma Tulin Kayhan, and Literatura 8
The geometrid genus Cleorodes is shown to belong in the tribe Gnophini (sensu lato) and not in Boarmiini as previously assumed. The conclusion is based on an analysis of morphological characters of a number of genera in these tribes. Moreover, the result is unambiguously supported by a phylogenetic analysis of DNA sequence variation in three nuclear gene regions (segments D1 and D2 of 28S rRNA, and elongation factor 1α) and a mitochondrial gene, cytochrome oxidase-1. The phylogenetic hypothesis is based on a combined sequence data set, which was analysed using direct optimisation.
In this paper we consider operators acting on a subspace $\mathcal M$ of the space $L_2(\mathbb{R}^m;\mathbb{C}_m)$ of square integrable functions and, in particular, Clifford differential operators with polynomial coefficients. The subspace ${\mathcal M}$ is defined as the orthogonal sum of spaces ${\mathcal M}_{s,k}$ of specific Clifford basis functions of $L_2(\mathbb{R}^m;\mathbb{C}_m)$. Every Clifford endomorphism of ${\mathcal M}$ can be decomposed into the so-called Clifford-Hermite-monogenic operators. These Clifford-Hermite-monogenic operators are characterized in terms of commutation relations and they transform a space ${\mathcal M}_{s,k}$ into a similar space ${\mathcal M}_{s^{\prime }\!,k^{\prime }}$. Hence, once the Clifford-Hermite-monogenic decomposition of an operator is obtained, its action on the space ${\mathcal M}$ is known. Furthermore, the monogenic decomposition of some important Clifford differential operators with polynomial coefficients is studied in detail.
Data on pupation and emergence dates for the nymphalid Purple Emperor butterfly Apatura iris have been collected at Basel, Switzerland, between 1982 and 2002. The butterfly has been shown to emerge on average 9 (males) to 12 (females) days earlier per decade, 19 and 24 days earlier respectively over the study period. Emergence dates relate strongly to spring temperatures, particularly with daily maximum temperatures for the months March to May. Temperatures for these months have increased significantly during this period (0.7°C to 1.8°C per decade). Three factors suggest that the strongest influence of the rise in spring temperatures has been on late larval instar growth and development: (i) May temperatures dominate emergence date models and larvae are feeding faster and for longer periods during this month, (ii) Salix caprea flowering date, a surrogate for bud burst, is excluded in stepwise regression models with temperatures and years suggesting that tree phenology may be less important than temperature effects on later development, and (iii) convergence of female and male emergence dates over time points to limits on earlier feeding in protandrous males. A negative consequence observed with earlier emergence dates is lethal extra broods.
This chapter is aimed at describing the relationship between individual rights and climate change agenda in the Czech Republic. Firstly, the authors provide a brief description of the Czech framework policy for climate change adaptation and specific acts dealing with the climate change. After that, the means of judicial protection in climate change disputes are analysed, with a particular emphasis on the role of administraitve courts. For better understanding, the authors present the most significant decisions of the Czech courts. They conclude that the courts may provide relatively effective protection against both public and private actors. however, climate change is still a new topic with which the applicants have not yet learned to work. In some cases, which are primarily concerned with other issues such as air pollution, climate change serves more as a supporting than a stand-alone argument. This is not likely to change any time soon, because the country is not affected by climate change to the degree it would be forced to act and immediate action would be deemed necessary. Moreover, the judicial review of the state policies is not allowed, even though at the governmental level, short-term economic goals are clearly preferred to the environmental agenda., Vojtěch Vomáčka, Ilona Jančářová., and Obsahuje bibliografické odkazy
Historical data sources on abundance of organisms are valuable for determining responses of those organisms to climate change and coincidence of changes amongst different organisms. We investigate data on the general abundance of Lepidoptera over an 89 year period 1864-1952. We related abundance to monthly mean temperature and precipitation and the winter North Atlantic Oscillation (NAO) index, and to numbers of migrants from an independent source. Abundances of Lepidoptera were significantly positively correlated with current year temperatures for May to September and November and significantly negatively correlated with temperatures in January. Numbers were also negatively correlated with rainfall for April and May and annual total of the current year and with August in the previous year. Abundance of Lepidoptera decreased significantly with an increasing winter NAO index. Increased overall abundance in Lepidoptera coincided significantly with increased numbers of migrants. The climate associations were very similar to those previously reported for butterfly data collected by the British Butterfly Monitoring Scheme; although warm and drier summers were generally beneficial to Lepidoptera populations, wet summers and winters and mild winters were not. We discuss the implications for Lepidoptera biology and populations in regions of Britain in the face of projected climate changes.
The author reported clinical characteristic features and risk factors for acute intestinal infections in 225 children (140 boys and 85 girls, mean age 1.5 years old). 90 (40%) patients aged up to 12 months, 101 (44.9%) were from 1 to 2 years old, and 34 (15.1%) were more than 2 years old. Most children were hospitalized in the first week of illness and had moderate severe course of disease. Severe forms of illness reliably more often were noted in children being on artificial feeding. Toxicdystrophic condition, severe forms and perinatal encephalopathy were prevailed in boys. Factorial analysis revealed 20 most significant factors with factorization fullness 70.8%. The most significant factors were F1( factor of hyperthermia duration) with 8.5% effect, F2 (factor of pain syndrome) 5.8%, F3 (factor of normal enzymatic activity of colon bacillus) 4.9%, F4 (etiological factor) 4.6%, as well as F5( factor of opportunistic flora of the intestine) 4.4%, respectively., Mukarram Shadjalilova, and Literatura
