the objective of this study was to evaluate the concentration and di.tribution of heavy metals in the sediments of Paulo Gorski Lake, as well as the metals’ bioavailability and potential ecological risk, and to define the anthropogenic and natural heavy metal contributions to the lake. the chemical elements calcium(Ca), cadmium(Cd), cobalt(Co), chromium(Cr), copper(Cu), iron(Fe), potassium(K), magnesium(Mg), manganese(Mn), sodium(Na), nickel(Ni), lead(Pb), and zinc(Zn) were quantified by flame atomic absorption spectrophotometry with two extraction methods to quantify the bioavailable and nonbioavailable fractions. the data were evaluated using multivari.te stati.tics and sediment quality *** sediment collection poi.ts(S1, S2, S3, S4 and S5) are different in terms of the concentration of heavy metals, except for S4 and S5, which were stati.tically equal. the bioavailable fraction of the elements in the sediment follows the sequence Pb > Cu > Mn > Zn > Ni > Cr > phosphorus(P) for all poi.ts. the elements Co, Cr, Pb, and Zn showed moderate to considerable contamination at all poi.ts. Only poi.ts S3 and S5 had moderate ecological risk. Urbanization has been affecting Paulo Gorski Lake via the input of chemical elements, especially Co and Pb. the poi.ts most affected by heavy metal contamination are S3 and S5 when the sedimentological sensitivity factor is considered. the lake has high hydrodynamics,causing some of the contaminants that enter the system to leave it, leading to potential negative impacts downstream.

作者： Jose Roberto Pereira Joao Bati.ta Rezende Ana Alice Vilas boas Universidade Federal de Lavras LavrasMGBrazil Fundacao Joao Pinheiro Belo HorizonteMGBrazil

the objective of this study is to analyze the ability of the public management of environmental problems faced by the municipalities in the state of Minas Gerais, Brazil. the theoretical elements that underlie this article are related to environmental management and municipal public admini.tration. We used the results of the natural vulnerability and the social potential of the indicator of municipal environmental management, as well as data on sanitation and waste disposal. the weaknesses of public admini.tration are located in the counties of low population group. these municipalities do not have suitable structure, formal organization and power of decisiveness in dealing with environmental problems.

2021年是巴西生活用纸行业艰难的一年,主要是由于生产成本的强劲演变,损害了公司的盈利能力,而这一年的低需求进一步加剧了这一点。这让我们估计,与2020年相比,2021年的产量下降了2%,这在巴西是不寻常的。自2000年以来,仅在2015年巴西生活用纸市场出现过低迷。2021年,在整个生活用纸市场,随着购物中心、办公室和餐厅因封锁而关闭,公共场所用/商用生活用纸(AFH)部门的业绩预计会下降,这导致该行业第三大重要产品手巾纸的消费量下降。

作者： thair M. Hamtini Ana Alice Vilas boas Luciana Pussi Santos tania Regina Vasconcellos Dias Department Computer information Systems The University of Jordan Amman Jordan the Department of Management and Economy The Federal University of Lavras Lavras Brazil

the objective of this study is to compare the ranking of the quality of e-commerce B2C portals in Brazil according to explicit criteria described in the article with the ranking according to the iNFO 100 ranking. theoretical research is first described, followed by the construction of eight self-established criteria of B2C portal quality measures and identification and compilation of requirements used by the i-Best, Opinia, E-bit and other institutes. After that, a portal quality evaluation is made by the web site content analysis;finally, a comparison of the rankings is presented. the obtained results showed that in spite of the lack of knowledge of the criteria adopted by iNFO100 [1], there could be agreement with the criteria adopted in this study, because there was agreement with the results for the Ponto Frio portal. therefore, it was concluded that the eight criteria used in this study can be useful in a quality analysis of B2C electronic portals.

人们寻求能藉以对任何艺术作品作最终评判的审美标准,就好象是在假定每一件这样的作品是一种恒定不变的实体,或者是,不管它是否有所变化.总是应当以同样的方式来评判.本文作者认为,这些假定似乎都不能成立。与之相反,作者认为艺术作品就如“美”或与之相似的事物一样,并非只有一种价值,其价值是颇具多重性的,一些人感受到作品的某些价值,另一些人则体味到另一些价值。没有一种居先的方法——除非是行政命令——能定夺众多价值中的哪一种才是在严格意义上“审美的”.这一见解通常又要遇上一种异议.因为恰巧存在着一些在“
