The determination of a range of boron concentration in the soil solution, evaluation of the effect of physico-chemical soil properties on boron concentration in the soil solution as well verification whether boron quantity in the soil solution is sufficient for nutritional needs of selected plants cultivated in Poland were comprised. Average boron concentration in the soil solution of Poland&rsquo;s cultivated soils ranges from 0.59 to 5.07 &micro;mol/L and is differentiated by physico-chemical properties of soil. Taking into account decreasing effects of soil properties on the increase of boron concentration in the soil solution, the soil properties can be arranged as follows: organic C &gt;<br />soil abundance in available boron &gt; soil texture &gt; soil pH. The minimum boron quantity observed in the soil solution of Poland&rsquo;s cultivated soils was not sufficient to fulfil nutritional needs of the plants. The maximum boron quantity observed secured nutritional needs of cereals and potatoes but not those of rape plants and sugar beets. Based on the study it can be concluded that the measurement of the concentration of boron in the soil solution can be used in the diagnosis of deficiency of this element for crops.

ABSTRACTThis work presents the analysis performed on a SiO2 film deposited from organometallic precursors with the aim of correlating their physico-chemical properties including electrical characteristics with processing variables. The characterization tools used in this study included SEM for film homogeneity; SIMS for the determination of total carbon content; FT-MS and Raman scattering spectroscopy for surface characterization. GC-MS was used to understand the electrochemical reactions taking place while performing I-V characteristics measurements.The use of these multiple characterization techniques pointed out to deposited films with reasonable deposition characteristics but poor electrical ones. Phase segregated heterogeneity's rich in carbonatious residues influenced the degradation of the electrical characteristics.

The present paper is focused on determination of the main parameters of Chlortetracycline. Chlortetracycline belongs to one of the most used family of antibiotics worldwide, Tetracyclines. Because of the large spectrum of infections which can be treated with this category of antibiotics there are attempts to find new derivatives from this class. The compounds derived from the same basic structure exhibit same chemical properties, that is why knowing in detail the main physico-chemical properties of Chlortetracycline could be a real help in synthesize new efficient derivatives. In order to evaluate the reactivity and biological activity HyperChem was used to establish the optimized structure, the electro-optical, the energetic and QSAR parameters. The solvatochromic methods allowed determining the intermolecular interactions types and their contribution to the spectral shifts of measured electronic absorption bands. Based on computational and solvatochromic results, the excited state dipole moment of Chlortetracycline was established by variation method.

Molecular descriptors play a fundamental role in chemistry and pharmaceutical sciences, being defined as a way to transform molecules into a set of numbers, allowing the mathematical assessment of the chemical information characterizing a molecule. This study presents the usefulness of molecular descriptors for the determination of physico-chemical properties of a series of new hallucinogenic amphetamines. Molecular descriptors of these compounds was performed with the Dragon 5.5 software. The chemometric processing of the information allowed the determination of structural correlations (similarities) between this class of designer drugs and an unknown compound.

<p>Thyme (<em>Satureja hortensis</em>) is a popular spice for food, which is also often used as a medicine for various ailments. This paper presents an artificial intelligence method applied for the objective determination of the most important physico-chemical variables affecting the quality of thyme, i.e. Principal Component Analysis (PCA). The results show that the main properties which significantly influence the nutritional value of thyme are moisture (MOIST), dry matter content (DRYM), protein content (PROT) and, to a lesser extent, carbohydrate content (CARB). Humidity is strongly and negatively correlated with the latter three variables. The main variable that ensures the similarity between the thyme samples having the same geographical origin is the monosodium glutamate content, which generates its delicious (umami) taste.</p>
