Opis:
Solanum melangena (eggplant) belongs to Solanaceae family. The common name of this frui and the plant is the same. It has different names in different countries such as eggplant, brinjal, baigan, balangie etc. Eggplant has been reported as a healthiest fruit due to the chemical constituents. The shape, size and colour of the fruits are also different. The genetically engineered eggfruits are also available. Some research works on eggplant are reported in different countries for different purposes. The present study has been taken into an account for the chemical elements present in flesh, skin and the seeds of eggplant grown in the soil and environmental conditions of Guyana. The investigation by the flame atomic absorption photometry shows the presence of Ca, Cd, Co, Cu, Fe, Mg, Mn, Pb and Zn at a varying concentrations in flesh, skin and seeds. In general the presence of calcium and magnesium as the higher values out of which concentration of calcium is 1366mg/kg in skin and magnesium as 2466 mg/Kg in seed.

Opis:
Novel cryogels based on pectin and chitosan were obtained by a cryotropic gelation method. Percentage of chitosan in the cryogels was estimated by elemental analysis. The obtained values were from 3.50 to 15.03 % for Apple pectin/Chitosan cryogels and from 9.44 to 17.64 % for Heracleum pectin/Chitosan cryogels. Internal structure and porosity of the cryogels were measured by scanning electron microscopy. According to the scanning electron microscopy, cryogels have a macroporous sheet-like structure. In the future, cryogels can be used in biotechnology and medicine as biocompatible, biodegradable materials.

Opis:
In this work, laser-induced breakdown spectroscopy (LIBS) analysis is optimized for direct estimation of elemental composition, thermal conductivity and hardness for Ni-Cr-Nb alloys. These alloys were chosen with a variable elemental content of niobium and chromium. The influence of laser energy and shot numbers on measuring line intensity was investigated. Based on the ratio between two spectral lines, calibration curves were formed to estimate the element concentration and LIBS results were confirmed with related energy-dispersive X-ray spectroscopy (EDS) data. Hardness and thermal conductivity estimation using LIBS were done by measuring the ratio between two spectral lines, plasma excitation temperature and electron density for different samples. Semi-empirical formulas correlated hardness and thermal conductivity with plasma temperature were established.

Opis:
Research concerning the effect of the application of waste sulfur pulp (doses: 10, 20, 30, 60 mg S • kg–1 d.m. of soil) on selected soil properties was carried out. The pulp contained sulfur in the elemental form. Before setting up the experiment, the soil had a slightly acid reaction (determination in 1 mol • dm–3 KCl) and was not contaminated with heavy metals. After conducting the incubation experiment, it was observed that the application of sulfur pulp led to a statistically significant (and proportional to the dose) increase in the content of available sulfur in soil. Application of waste caused a decrease in soil pH and an increase in the mobility and availability of Zn, Cd and Mn (extracted with 0.01 mol • dm–3 CaCl2). In relation to soil without waste, more Zn, Cd and Mn (by 4–51%, 9–24% and 0.1–31%, respectively) was determined. Liming reduced the acidifying effect of the introduced waste – after 150 days, only soil with the highest dose of sulfur pulp was characterized by a statistically significantly lower pH than the soil without the waste addition. An increase in the rate of sulfur oxidation was also observed – after 150 days of the experiment, more sulfate sulfur (by 14.4–34.5%) was determined, with respect to treatments of the unlimed series. A considerably lower content of Zn, Cd and Mn was determined in the limed soil than in the unlimed one. Regardless of waste dose and date of analysis, the soil contained a trace content of mobile forms of Cu, Cr, Ni and Pb.

Opis:
Citrullus colocynthis (L.) Schrad. (Watermelon) belongs to Cucurbitaceae family. Watermelon can be correctly referred as either fruit or vegetable. The watermelon has attracted attention of many researchers due to various kinds of its medicinal properties. A watermelon has basically four parts as rind, white flesh, red flesh and seed. There are a number of varieties of watermelon in which the central ripped part may be dark red, light red, pink, or yellow. The new variety is watermelon is also available without seed or very few seed called seedless watermelon. In the present investigation the dark red flesh variety of watermelon was chosen. Ca, Cu, Fe, Mg, Mn and Zn were investigated in rind, white flesh, dark red flesh and seed. It was found interesting that the amount of calcium (Ca) in all these four parts was very high and highest in the white flesh (unripped) of watermelon.

Opis:
Various types of neuromuscular diseases differ in symptoms, pathology, and clinical picture but one of their common elements is muscle weakness, which could lead to human motor activities impairment and in many cases to shortening of life span and even death due to respiratory failure. That is why it is very important to better understand the underlying causes of these diseases to be able to implement new methods of treatment more effectively. This paper presents the results of the elemental analysis of human muscular tissues affected by dystrophy and myopathy. For this purpose, the particle-induced X-ray emission method was used, which is perfectly suited for measuring light elements. The samples were analysed for differences in the elemental composition of Na, Mg, P, S, Cl, K, Fe, Zn, and Br. The results were presented in the form of elemental concentration maps and a thorough statistical analysis of the obtained data using the advanced statistical methods.

The fascial system is an integral part of the musculoskeletal system. It is a three-dimensional network of connective tissue spreading ubiquitously throughout the body, surrounding muscles, bones, internal organs, nerves, vessels, and other structures. The basic biophysical properties of the fascial system are determined by its structure and chemical composition. This study aimed to determine the elemental composition of pathologically unchanged fascia lata of the thigh, collected during autopsies on humans and dogs. The wide spectrum of elements analysed included both macro and micro elements. The analyses were conducted using scanning electron microscopy with X-ray microanalysis (SEM-EDS). Concentrations of the following macro and micro elements were dermined: C, N, O, Na, Mg, Al, Si, P, S, Cl, K, Ca, Ti, Fe Co, Ni, Cu, and Zn. The obtained results showed significant differences between human and canine fascia lata regarding the content of most of the examined elements (p < 0.05), except for N. These data may in future provide a starting point for the establishment of reference values for the content of various elements in normal fascial tissue and may also serve to verify the usefulness of experimental animal material as a substitute for human tissue.

Opis:
The study of the geochemical composition of sediments was undertaken to evaluate the degree of weathering and appraise the relative proportion of mafic and felsic rock materials being transported from source to sink. Thirty-three surface sediment samples collected from the creeks were used for particle size and chemical analyses. An inductively coupled plasma-Mass Spectrometer was used to determine the elemental composition of the sediments. The clay dominated Yewa and western Badagry creeks gave evidence of higher average concentrations of Ni, Sr, Y, Nb, Sc, Co, V, and Th than the eastern end of segment of Badagry Creek. The data generated from elemental ratios such as Al 2 O 3 /TiO 2, TiO 2 /Zr and binary plots of Th/Sc-Cr/Sc, Th-Sc, Y/Ni-Cr/V, TiO 2 -Zr and ICV-CIA (index of compositional variability against chemical index of alteration) showed that source sediments are composed of upper and lower crustal compositions. Also, the creeks were marked by their variation in terms of the proportion of felsic and mafic components. For instance, Yewa and western Badagry creeks are more enriched in mafic constituents, whereas the enrichment of felsic materials is significant at the eastern end of Badagry Creek. Inferring from the chemical index of alteration and plagioclase index of alteration (PIA), the Yewa and western Badagry creeks have been moderately to intensely weathered and incipient weathering was identified in the eastern end of Badagry Creek.

An investigation of single-base propellants has been conducted. The ageing process during extended storage of single-base propellants (SBP) in nonheated military stores and a heated building has been investigated by elemental analysis. Two or three different absorbencies around the band at 1650 cm-1 were observed by FTIR spectroscopy. In this way, not only the denitration of the propellants was determined, but also cleavage of -O-C- bonds between the glycoside rings in the nitrocellulose macromolecules. The latter process was confirmed by the swelling of the SBP.

The physicochemical properties of solid wastes were determined to unravel the individual components of solid wastes such as density, moisture content, and percentage mass. The chemical composition of each waste component was also determined. Methods adopted in the determination included the load count and mass volume methods, the proximate and ultimate analysis method. Collectively, the percentage chemical constituents were obtained from the different solid waste samples analyzed. Energy values obtained from the constituents are 47.6 and 47.10 kJ/kg when Dulong’s and Davies’ formula were applied, respectively. The results revealed that paper and cardboard, metals, plastics, and wood make up the highest composition in the five major waste dumpsites studied in Awka, Nigeria. It also showed that carbon and oxygen contents are high in most of the solid waste components when compared to other chemical constituents and that these wastes can be converted to useful energy in furtherance of sustainable development.

Reactivity of (3-aminopropyl)trimethoxysilane with cellulose. The paper presents the results of tests for the reactivity of (3-aminopropyl)trimethoxysilane (APTMOS) with cellulose. The cellulose was treated with aqueous ethanolic solution of silane in two concentration: 5% and 20%. The reactivity of APTMOS with cellulose was analysed using instrumental methods: attenuated total reflectance Fourier transform infrared spectroscopy, atomic absorption spectrometry and elemental analysis. In the FTIR spectra of silane-treated cellulose, the bands of Si-O, Si-C and N-H bonds were detected. The analysis of silicon and nitrogen concentration in treated cellulose confirmed the presence of silane in cellulose structure. The presented results indicate that APTMOS forms chemical bonds with cellulose.
Reaktywność 3-(aminopropylo)trimetoksysilanu z celulozą. W pracy przedstawiono wyniki badań reaktywności 3-(aminopropylo)trimetoksysilanu (APTMOS) z celulozą. Celuloza była traktowana etanolowym roztworem silanu w dwóch stężeniach, wynoszących 5 i 20%. Reaktywność APTMOS z celulozą była analizowana z wykorzystaniem metod instrumentalnych, w tym spektroskopii osłabionego całkowitego odbicia w podczerwieni z transformacją Fouriera, atomowej spektroskopii absorpcyjnej oraz analizy elementarnej. W widmach FTIR celulozy poddanej działaniu silanu obserwowano pasma pochodzące od wiązań Si-O, Si-C i N-H. Analiza stężenia krzemu i azotu w modyfikowanej celulozie potwierdziła obecność silanu w strukturze celulozy. Przedstawione wyniki wskazują, że APTMOS tworzy wiązania chemiczne z celulozą.

Opis:
Four seasonal sampling campaigns successively in April, July, September 2008 and February 2009 took place at Świder, a town located to the south-east of Warszawa, Poland. Three particle size fractions of particulate matter were collected by a NILU (The Norwegian Institute for Air Protection, Norway) sampler. The following elements were determined by the energy dispersive X-ray fluorescence (EDXRF) method: K, Ca, Ti, Cr, Mn, Fe, Cu, Zn, Br and Pb. The highest mean mass concentrations in fine and medium fractions were observed in April 2008 and February 2009. For a coarse fraction, the highest values of mass concentrations were observed in April and September 2008. Ca, Mn and Fe existed mainly in the coarse fraction. These elements probably came from the southern direction. Zn was divided between three fractions equally. In February 2009 the highest Zn concentrations were observed in the medium fraction. Pb existed mainly in the fine and medium fractions. The highest values of Pb concentrations were observed in February 2009. Bromium existed in the fine fraction. Correlations were observed between Ca, Mn and Fe concentrations. Correlation factors were about 0.8 for the coarse fraction. For other analyzed elements, the correlation coefficients were small. Basing on the backward trajectories and elemental concentrations of particulate matter (PM), it was confirmed that in winter the main influence on air quality is caused by pollution coming from coal combustion in local houses, heat and power plants working in urban areas. In summer the main influence on air quality is caused by pollution from sources in rural cultivable areas. The improvement of air quality is possible by decreasing the emission, using coal with a small level of harmful compounds and whole elimination of plant preventive agents and using fertilizers with a small content of unwanted elements.
