Abstract Transition to a more sustainable economy and the consequences of the Kyoto protocol on global climate change, includes a shift of feedstock for energy and chemical industries from fossil fuels and petrochemicals to renewable resources. The use of vegetal fibers as major source of renewable resources represents a valuable alternative both from economical and environmental points of view. Traditionally, vegetal fibers are widely used in textile industry, paper manufacture, and packagin...

Abstract The flotation tailing pond Bozinta is located at 5 Km West from Baia Mare town. It is closed and is preparing for ecological reclaiming. Preliminary investigations have been made on the meteorological and climatologic indicators of the site. The temperature, air relative humidity, the wind speed, the rain values and the soil temperature have been measured during the vegetation period of 2008 year. The air temperature on the tailing pond is always 1?ˇ2 0C higher than the values regist...

AbstractThe role of human resources in agricultural exploitations proved to be an essential matter due to the decisive influence on theagricultural crop efficiency and production results. There exist particularities regarding the calculation of the human resourcesnecessary in vegetal crop production, animal husbandry and other activities connected with agriculture. From an economicalfinancialpoint of view, the analysis of human resources efficiency is based on two indicators, as follows: labour ...

Abstract Our researches have focused primarily on variations of different biophysical and biochemical effects on vegetal and animal material at macro, micro, and ultra-micro scale resulted from changes in environmental condition. Growth and spectral parameters of rapeseed seedlings from seeds exposed to UVA-VIS radiation with a high pressure lamp which emits incoherent continuously radiation for different time periods were examined 14 days after germination. These studied parameter...

Abstract This paper presents the results obtained using the prehydrolysis treatments of rapeseed stalks depending on regime and the catalyst. The vegetal materials were subjected under different temperature conditions and then characterized for the yield reducing substances. The differences between samples have been established by using FTIR and depend on the successive hydrolytic treatments of dynamic and static regime in the presence of various catalysts. The experimental data show that th...

Abstract The juglone (5-hydroxy-1,4-naphthalenedione) can be found in the leaves and fruits of the black walnut (Juglans nigra L.). This substance has an inhibitory effect on the growth of the vegetal species, phenomenon which is named allelopathy. The inhibitory effect of the 50-100% concentration of this water extract, prepared from the black walnut fruits, on the seeds germination, plantlets growth and peroxidasic activity – registered in the seedlings roots – was poor, compar...

Abstract In rural areas of Romania and other developing countries wounds and dermal affections represent one of the five most common reasons for people seeking medical care. The use of traditional medicines to treat many of these conditions has received little research or policy attention. The present work addresses the discovery of non-toxic treatments for dermal affections, and aims to prepare – based an environmentally friendly technology, and characterize hydrogels based on gelatin...

Composting is one of the most used biowaste recycling method. The paper highlights the influence of some natural organic additives such as cattle and poultry manure on the quality of compost and especially on the content in microelements and heavy metals. The mature compost showed the following macro and microelements concentrations: total N 1.12-1.38%, P 0.56-0.90%, K 0.68-0.92%, Ca 1.18-1.70%. Mg 0.38-0.66%. The compost that included cattle manure showed the highest content in humic substa...

This paper aims at identifying the specific and phytocenotic diversity, as well as assessing the conservation status of habitats across the Protected Natural Area Racâş-Hida - Site of Community Interest from Romania (ROSCI 209), located in the Sălaj County. The target is to identify taxa and types of natural habitat whose conservation requires them designation as special conservation areas, as well as to identify solution for the sustainable management of the range. As a resul...

In this paper low power microwave radiation impact on Zea mays root meristeme tissues was investigated. Seeds with uniform genophond were exposed for 3 hours at 10 W incident power level in controlled condition to continuous wave at three different frequencies (0.6 GHz, 1 GHz and 2.5 GHz) and let to germinate after electromagnetic exposure. Dosimetric assessment made experimentally and computationally allowed the proper energetic characterization of the interaction between vegetal tissue and rad...

Building industry is a very large domain in the global economy and it has a lot of consequences over the environment through many and different aspects. These consequences are various, from the more and more extended area of construction up to gas emissions released during materials manufacture and transportation, construction process, exploitation of buildings and, finally, their deconstruction. The concrete, the most used material in construction industry all over the world, must become green...
