Economic and Geografical Aspects of Water Use in the Prut River Basin (The sector of the Republic of Moldova)

Abstract

The purpose of this research consists in the elucidation of spatial and economic aspects of the water use in the Prut river basin. The main topics presented in this paper are: 1) the dynamics of water use; 2) spatial and branch profile of water use and its dynamics: 3) existing problems in the evaluation and monitoring of water use; 5) efficiency of the implementation of economic instruments of water management. To achieve these objectives were used traditional methods of geographical and economic research. Also, the content of the present study is focused on the methodology to elaborate the management plans of hydrographical basins and their chapters on the status of water resources and water bodies and on economic analysis of water use in the Prut river basin.

Effects of Modifying Agents on the Dyeability of Cotton Fabric using Malachite Green Dye

Abstract

Changes in thermodynamic parameters as a result of modifying agents on dye uptake of cotton fabric using malachite green (MG) dye was investigated in this study. Five modifying agents {Acetic acid (CH3COOH), hydrated Sodium carbonate (Na2CO3.10H2O), Sodium Chloride (NaCl), Ammonium sulphate ((NH4)2SO4) and Hydrogen peroxide (H2O2)} were used on cotton fabric. The equilibrium exhaustions (%E) were determined before and after modification of the cotton fabric at different concentrations which were 88.24%, 80%, 77.14%, 65.10% and 30.88% for CH3COOH, NaCl, (NH4)2SO4, Na2CO3.10H2O and H2O2 respectively. The results also showed a correlation between the standard affinity(-Δμθ) of dye on cotton fabric and the equilibrium exhaustion. The values of entropy (ΔSθ) and enthalpy (ΔHθ) change revealed the feasibility (spontaneity) and exothermic nature of the reaction. The optimum parameters were attained in acidic solution (CH3COOH) at the highest temperature (70 °C) of dyeing as it showed the highest % efficiency of 88.24%. This work established that modification of cotton fabric with modifying agents is one of the best route to improve the affinity between dye and fabric as it reduces stress, amount of dyes wasted in dyeing, time required to achieve satisfactory results leading to a cost effective environmental friendly approach in the field of cotton dyeing.

Carbonaceous Soot from Thermal Decomposition of Kerosene: A Pioneering Report for Paint Preservation

Abstract

Bacterial resistance to conventional paint biocides is widely documented. However, an investigation regarding the preservative potential of carbonaceous soot as a viable alternative is novel. Fresh paint samples (SA, SB and SC) were collected in duplicates from a reputable paint manufacturing company in Lagos, Nigeria. SA was produced with conventional paint biocide, SB and SC were without biocide. All samples were inoculated with 0.032 × 106 cfu/mL of Pseudomonas aeruginosa PA01 (NC 002516.2) previously isolated from spoilt paints and identified by the 16S rDNA analysis. SB was supplemented with crude soot (10 g/L of distilled water) at 200 mL v/v. The preservative efficiency of soot was investigated by monitoring the bacterial population (BP), optical density (OD600nm), viscosity (VIS), the transmittance (TR) and specific gravity (SG) of the samples bi-weekly for 14 weeks. BP increased drastically from 0.032-31.61 × 106 and from 0.032-112.93 × 106 in SA and SC respectively. In contrast, SB increased from 0.032-24.63 × 106 by week 4 but reduced from 24.63 – 10.95 × 106 by week 14. The OD of SA increased from 1.55 to 1.98 by week 8 and decreased to 1.74 by week 14. SB had a decrease from 1.60 to 1.49 by week 4 and increased to 1.63 by week 14, while SC increased from 1.59 to 2.54 by the 14th week.TR increased from 1.80 to 2.30 and 1.25 to 2.20 in SA and SC respectively. In contrast, TR decreased from 2.00 to 1.25 in SB. The viscosity and specific gravity values of all the samples decreased with time with the highest decrease observed in SC and the lowest in SB. The test crude soot showed preservative potential in paints.

Optimization Problems and Solutions of Forest Resources Management in Moldova

Abstract

The main problems of forest management in Moldova are: consumerist approach of the forest fund; the superficial management of indirect economic functions and ecological functions; illegal logging, overgrazing, massive pollution with domestic waste; the closed character of decision making in the forestry sector; the limitation of population's access to forest lease land and the abuses in this field; cumulating and duplication of management functions; the inefficient realization of evaluation and integrated monitoring of forest fund, especially in the communal forests.

Economic and Financial Aspects of Water Management in the Dniester Basin (The Sector of the Republic of Moldova)

Abstract

The main topics presented in this paper are following:1 Essence and the tools of the economic mechanism of management of water resources; 2 Taxes on water consumption; 3 Tariffs for services of water supply and sewerage; 4 administrative penalties for infringements of use and protection of water resources; 5 The grants for the rational use and protection of water. In the Dniester Basin have been concentrated the majority of water resources, of urban, industrial and agricultural centers. Thus, this basin holds over 90% of water consumption, most of which are captured from surface sources and used by industrial enterprises from the left bank of Dniester, especially by Thermoelectric Plant (TEP) from Dnestrovsk. On the right bank of Dniester it is noted communal enterprises, agricultural and food industry, and in most of the localities water is captured from groundwater sources. Actual amount of water tax is very low, which conditioned the increased of water consumption and irrational use of these limited resources
