Factors affecting the distribution patterns of aquatic macrophytes
Authors: Dar Naseer Ahmad , Pandit Ashok Kumar , Ganai Bashir Ahmad 
Published: January 2015

Abstract
Aquatic macrophytes constitute important components of many freshwater ecosystems. The manifold role of aquatic macrophytes in freshwater habitats is closely linked to their distribution, which in turn depends on a myriad of factors. Foremost, among these are light, water temperature, water quality changes and nutrient enrichment, sediment composition and fluctuations in water levels. Light and temperature are of paramount importance in determining the distribution (with depth, season and latitude), thereby influencing productivity and species composition as well. Sediment compositions markedly affect the growth rates of macrophytes which in turn have a profound influence on the distribution of aquatic macrophytes. Water quality changes and nutrient enrichment can cause considerable variations in the species richness, composition, and density of aquatic vegetation. The reduction in water levels could bring drastic changes in the species composition and distribution of macrophytes. Factors associated with competition, herbivory, land use and land cover changes etc. also play an important role in shaping macrophyte distribution and community structure. In this review we examine both biotic and abiotic factors that influence the structural attributes like species composition, distribution, abundance and diversity of aquatic macrophytes.
Anthropogenic change in water bodies in the southern part of the Silesian Upland
Authors: Machowski Robert , Noculak Marek 
Published: January 2015

Abstract
The paper analyses the anthropogenic change in water bodies in the southern part of the Silesian Upland as exemplified by the town of Knurów. The assessment was based on topographic maps from the years 1827-1828, 1928-1936, 1960 and 1993, and on a 2011 orthophotomap. The cartographic materials used were processed as required for analysis purposes. Maps were calibrated in the Quantum GIS program on the basis of map corner coordinates and using the common points method. In Knurów, four main types of water bodies were distinguished with respect to their origins: reservoirs impounded by dams, flooded mineral workings, industrial water bodies and water bodies in subsidence basins and hollows. Historically, the first water bodies to appear were reservoirs impounded by dams, which dominated until the 1930s. They later fell into disuse and were completely dismantled. Water bodies in mineral workings formed in the early 20th century and were associated with the excavation of raw materials for producing bricks. The period of their greatest significance were the 1960s, when they constituted slightly more than 46% of water bodies in total and accounted for nearly 40% of overall surface area. At the end of the 19th and at the beginning of the 20th century, industrial reservoirs began to appear. Within the town of Knurów, those were sedimentation tanks that held mine water, washery effluent, backfill and cooling water, fire-fighting water pools and tanks, tanks at sewage treatment plants, industrial water tanks and others. Presently, these account for 41.4% (29) of the total number of water bodies and have a total surface area of 32.0 ha (25,2%). Within the study area, water bodies in subsidence basins and hollows only began to form in the second half of the 20th century. In 2011, such water bodies numbered 38 (54.3%) and occupied an area of 90.4 ha (71.2%).

Published: January 2015

Abstract
The paper is focused on the processing of 3D weather radar data to minimize the impact of a number of errors from different sources, both meteorological and non-meteorological. The data is also quantitatively characterized in terms of its quality. A set of dedicated algorithms based on analysis of the reflectivity field pattern is described. All the developed algorithms were tested on data from the Polish radar network POLRAD. Quality control plays a key role in avoiding the introduction of incorrect information into applications using radar data. One of the quality control methods is radar data assimilation in numerical weather prediction models to estimate initial conditions of the atmosphere. The study shows an experiment with quality controlled radar data assimilation in the COAMPS model using the ensemble Kalman filter technique. The analysis proved the potential of radar data for such applications; however, further investigations will be indispensable.

Authors: Gao Yang , Zheng Weifang , Cao Xiaoming , Chen Shaolei 
Published: January 2015

Abstract
In light of the issue of radiolysis of the solvent system in PUREX process, alpha and gamma radiation stability of tributyl phosphate (TBP)/kerosene (OK) have been studied in this paper, in which 238Pu dissolved in the organic phase and 60Co are selected as alpha and gamma irradiation sources, respectively. The amount of the degradation products not easily removed after the washing process has been measured by the plutonium retention. The effects of the absorbed dose, the TBP volume fraction, the cumulative absorbed dose and the presence of UO2
2+ and Zr4+ on the radiolysis of the solvents have been investigated. The results have indicated that the Pu retention increases with the increase of the absorbed dose after alpha or gamma irradiation, and is larger for the solvent containing less TBP. There is competition between UO2
2+ and Pu4+ to complex with the degradation products, and Zr4+ accelerates the radiolysis of the system.

Published: January 2015

Abstract
Background and Purpose: The objective of this research was to explore the perceptions of the users regarding Internet financial reporting practices in Slovenia. With this research, we wanted to determine what the perceptions of the users are regarding the reliability, credibility, usefulness and sufficiency of online accounting information and how their expectations regarding the content of accounting information differ from the actual situation.
Design/ Methodology/ Approach: This research has two parts: in the first part, we summarised the actual situation regarding publishing of internet financial reporting on a sample of large companies in Slovenia (n=110) while, in the second part, we conducted a survey with which we assessed the expectations of users as regards of accounting information (n=127). We then compared users’ expectations with the actual situation, analysed by evaluation of 110 websites of Slovene companies.
Results: In the research we found that 52.6% of companies publish their accounting information on their websites and that on average 40.2% of users actually make use of this information We found that users have evaluated all four of characteristics: reliability, credibility, usefulness and sufficiency above average, whereby they evaluated usefulness with the highest grade and sufficiency with the lowest.
Conclusion: The results of this research can offer companies a feedback on users’ expectations, particularly in cases where these expectations are greater than the actual situation. We have determined that users generally want information that indicates the financial status of a company (such as the Rating Report and data on the company’s liquidity), as these information are currently expected by users but available information do not meet their need in full.

Published: January 2015

Abstract
Background and Purpose: Providing a win-win situation for enterprises and the environment is raising the importance of eco-innovation. This article sheds light on the eco-innovation activities implemented within the clusters of the South Eastern European region (hereafter the SEE region). The main objective of this paper is to provide an outline of the situation pertaining to the implementation of eco-innovation activities in analyzed clusters.
Methodology: Empirical evidence is provided through the performance of survey research with a sample of 52 clusters, encompassing 11 countries of the SEE region. The basic research method used in this research was a questionnaire developed for cluster organizations, with which we gathered the data and afterwards conducted descriptive statistics.
Results: The findings demonstrate that the majority of analyzed clusters implement eco-innovation activities. The results indicate that 40 clusters out of 52 in all have set objectives with regard to eco-innovation support in their national or regional programs, followed by 35 clusters, which include objectives related to eco-innovation in their cluster strategies, and lastly, only 15 clusters are primarily focused on eco-innovation. Hence, our study depicting the current situation regarding the implementation of eco-innovation activities in analyzed clusters and clusters’ orientation towards eco-innovation leads to us the discussion of why such differences in clusters occur.
Conclusion: The huge differences related to the implementation of eco-innovation activities in clusters of the SEE region, can also reflect the level of the national/regional development in terms of economic indicators such as GDP and, at the same time, offer room for a lot of improvement, and an exchange of best practice.

Published: January 2015

Abstract Maria do Carmo Vaughan Bandeira (1902-1992) is a little-known Brazilian botanist who worked for about ten years at the Botanical Garden in Rio de Janeiro, Brazil. She made approximately 800 botanical collections, including mosses (her special interest) but also lichens, fungi and occasionally angiosperms. She studied at La Sorbonne in Paris, corresponded with leading botanists in different fields of botanical research in Europe and the USA, and represented the Rio de Janeiro Botanical Garden in many instances. At age 29 she abandoned a promising research career and entered a convent in Rio where she lived for 60 years as a cloistered nun.

Attitudes of Iranian Male University Students Toward Sport and Exercise with Reference to Age, Educational Level, and Field of Study
Authors: Mirsafian Hamidreza 
Published: January 2015

Abstract
This article aimed to discover the attitudes of Iranian male university students toward sport and exercise. This study is based on the same research as another published paper regarding the attitudes of Iranian female students toward sport and exercise. Participants (N = 821) were selected from different educational levels and fields of study from among 12 public universities. Data were collected by a modified and developed version of Kenyon's scale (1968), which measures the attitudes of people toward physical activity. For the analysis of the data, independent sample t-test and multivariate analysis of variance (MANOVA) were employed (p < 0.05). The results indicated that the attitudes of the respondents can be identified as fitness (3.96 ± 1.02), catharsis (3.84 ± 0.80), social (3.82 ± 1.10), aesthetic (3.03 ± 1.14), vertigo (2.15 ± 1.16), and ascetic (2.07 ± 0.79). Furthermore, it was found that various demographic and social characteristics affected participants' attitudes toward sport and exercise (p < 0.05). Based on the results, it was concluded that the sport programs should be organized around students' dominant attitudes toward regular activities. In addition, planning and organizing sport programs with regard to the wide attitudinal differences between male and female students could be a big step toward improving students' participation rate in sporting activities at Iranian universities.

The Siret River are used as raw water source for different municipal water supply systems, yet the Siret River are used as receiving bodies by some inhabitants and industry. In the study the quality of the Siret River water was determinate using a Water Quality Index (WQI). Results are presented from a field study performed on the Bistrita, Moldova, Suceava, Siret, Şomuzu Mare, Trotuş and Tributary River in the study area Siret Basin Romania. The main objective of this study was to determine is to find correlations land use to indicators physical-chemical of water quality, to investigate pollution source is more responsible for river water quality. This is of interest not only research context, but also for supporting and facilitating the application analysis postullend in the Water Framework Directive (WFD) (2000/60/CE) for the establishment of programmers of measures. For this purpose a slightly impact pollution source municipal wastewater treatment, land uses, urban, forest, agriculture and mining was selected and intensively monitored during six years January 2006 - December 2011, sampling was determined to meet the WFD standards for confidence in twenty two different control section of the Siret Basin. The main measures to reduce emissions to the Siret River were calcium, ammonium, sulfate, residue fixed (RF), sodium, chloride, free detergent and municipal wastewater treatment, concentrated on point emission. The main contributor to diffuse this parameters increased when more percentage of land was dedicated to industry and urban and less to forest and mining.

Authors: Dragomir Carmelia Mariana , Constantin Daniel Eduard , Voiculescu Mirela , Georgescu Lucian Puiu Georgescu 
Published: January 2015

Abstract
One way of monitoring the atmospheric pollution is to estimate anthropogenic emissions. This paper presents a study of PM10 emissions in a city SE of Romania (Braila) for the period 2009-2012. PM10 emissions decrease from 304.75 t in 2009 to 78.01 t in 2012. Using data from the Environmental Protection Agency Braila and the METI-LIS dispersion model, four maps were produced in order to estimate the spatial distribution of PM10 emission in each year. Results of dispersion models show that the air quality can change abruptly between points at few meters away. Expectedly, PM10 emissions increase towards the centre of the city centre, are generally higher in the vicinity of busy streets and roads.
Informal Collection of Household Solid Waste in Three Towns of Anambra State, Nigeria
Authors: Egbu Anthony , Okoroigwe Decklan 
Published: January 2015

Abstract
Management of urban solid waste implies the collection, transfer, treatment recycle, reuse and disposal of such waste. Collection of urban household solid waste traditionally rests with government agencies designated with such responsibility. Solid waste collection begins from storage at the household level to the final treatment or disposal point and represents the most important aspect of urban solid waste management. Little has however been written on urban household solid waste collection in Nigeria. Using empirical data from three urban areas of Anambra State, Nigeria, the paper examines the place of informal private solid waste collectors in household solid waste collection. The ANOVA technique is used to test the null hypothesis that the sample means of the distance to designated community/street solid waste collection containers in the residential neighbourhoods of the three towns are equal. We conclude on household patronage of informal private solid waste collectors as against government provided community/street collection containers in the areas studied.

Published: January 2015

Abstract
The sewage sludge from wastewater treatment plant of Iasi, a city with 300,000 inhabitants, for domestic and industrial origin, was stored in a mud pond arranged on an area of 18,920 m2. Chemical analyzes of the sludge showed that, of all the chemical elements determined, only Zn is found at pollutant level (5739 mg∙kg-1), i.e. almost 30 times more than the maximum allowable limit for Zn in soil and 45 times more than the Zn content of the soil on which the mud pond has been set. Over time, the content of Zn in the mud pond, but also from soil to which it has been placed, has become upper the normal content of the surrounding soil up to a depth of 260 cm. On the other hand, the vegetation installed on sewage sludge in the process of mineralization, composed predominantly of Phragmites, Rumex, Chenopodium, and Aster species had accumulated in roots, stems and leaves Zn quantities equivalent to 1463 mg Kg-1, 3988 mg Kg-1, 1463 mg Kg-1, respectively, 1120 mg∙Kg-1. The plants in question represents the natural means of phytoremediation, and sewage sludge as such may constitute a fertilizer material for soils in the area, on which Zn deficiency in maize has been recorded. In addition, the ash resulted from the incineration of plants loaded with zinc may constitute, in its turn, a good material for fertilizing of the soils that are deficient in zinc.
The Importance of Water Temperature Fluctuations in Relation to the Hydrological Factor. Case Study – Bistrita River Basin (Romania)
Authors: Cojoc Gianina Maria , Romanescu Gheorghe , Tirnovan Alina 
Published: January 2015

Abstract
The increase in most components of the climate over the past 50 years, including air and water temperature, is a real phenomenon, as attested by the numerous specialized researches according to IPCC (2013). The water temperature is one of the most important climatic components in analyzing the hydrological regime of the Bistrita River (Romania). The thermal regime of the Bistrita River basin and the frost phenomena associated with the risk factor are particularly important and frequently appear in this area. In recent years, under the Siret Water Basin Administration, this parameter was permanently monitored, so we could do an analysis, which shows that the water temperature fluctuations, influenced by air temperature, lead to the emergence of the ice jam phenomenon. The present study aims to analyze the water temperature, as compared to the air temperature, and the effect of these components on the liquid flow regime (the values were recorded at the hydrological stations on the main course of the Bistrita River). The negative effects resulted from the ice jam phenomenon require developing methods of damage prevention and defense. The frost phenomena recorded after the construction of the Bicaz dam are analyzed in this article

Authors: Nedealcov Maria 
Published: January 2015

Abstract
Increase the intensity and frequency of the weather and climate risks contribute to compromised harvests in recent decades. Analysis of financial losses indicates that in 2007 and 2012 substantial values were reached. In this context it is important to know their regional peculiarities of manifestation both in present and in the years to come. The results shows that pronounced manifestation of the weather and climate risks in recent years (2000-2013) contributed to the decline of winter wheat harvest of 2q / ha compared with the harvest that is expected in the 2020s - calculated according to the most drastic SRES B2A scenario. The results are extremely necessary to take adaptation measures to new climatic conditions and to food security for the future in the Republic of Moldova.
Considerations on Temperature Inversions in the Lower Troposphere in the 2001-2002 Cold Season, South of the Carpathian Mountains
Authors: Florentina Bărcăcianu , Liviu Apostol 
Published: January 2015

Abstract
Temperature inversions are characterized by negative vertical thermal gradients (Donciu, 1953, Ţâştea, 1965, Bogdan, 1971, Neacşa, Frimescu, 1981). The most frequent manifestation is in the depression areas because in addition to radiative cooling and better possibility to store cold air invasion, it also takes place the accumulation and of air flow of cold air due to gravity. The area south of the Carpathians, shows depression features, gaining titles like: carpathianbalkanic bucket (Bălescu, 1962), carpathian-balkanic sink (Ion-Bordei, N. 1988). In this space the inversions occupy the entire area, proof being the values from low altitude stations similar to those from mountain peaks, while the middle part of the slope remains wormer.
