Opis:: In this study, the functional polymers containing heterocyclic ligands were synthesized by microwave modification of a crosslinked poly(vinylbenzyl chloride–divinylbenzene) matrix with 4-tertbutylpyridine, pyrrolidine, and 3-morpholinopropylamine. The sorbents were used to recover Ag(I) from the synthetic and real chloride solutions (4.00 mol/dm3 of NaCl, 0.100 mol/dm3 of HCl). The best Ag(I) sorption was achieved from synthetic and real chloride solutions in the case of pyrrolidine resin (16.2 and 16.7 mg/g, respectively). The sorption kinetic data were well fitted to the pseudo-first-order kinetic model. The degree of silver desorption was approximately 90% using a 1.0% potassium cyanide solution in a 0.50% hydrogen peroxide solution. All resins showed good selectivity for Ag(I) compared to Cu(II), Pb(II), Co(II), Ni(II), and Zn(II) in real chloride solution. On the basis of this study, it can be concluded that the obtained sorbents can be used to recover Ag from various sources such as ores, wastewater, and jewelry scraps.

Opis:: 85Sr was produced via the 85Rb(p,n)85Sr reaction. Rubidium chloride deposition on copper substrate was carried out via the sedimentation method in order to produce strontium-85. Optimum conditions were achieved as a result of several repeated experiments with different amount of ethyl cellulose (EC) and acetone. 520 mg of RbCl, 208 mg of EC 4 mL of acetone were used to prepare a layer of enriched rubidium chloride of 11.69 cm2 area and 62.2 mg/cm2 thickness. Target quality control was done by a SEM photomicrograph and a thermal shock test. The deposited target was irradiated at a 20 ěA current and a 15 MeV proton beam for 30 min. No degradation was observed. The RbCl surface following bombardment was white, except the central area that was light brown and also without any crack or peeling off.

Opis:: Optimization of selective extraction conditions for separating plutonium from uranium and thorium standard solutions using methytrioctylammonium chloride (Aliquat 336) as extracting agent is presented. Influence of such parameters as concentration of extracting agent and nitric acid, and kind of reducing agent on the efficiency of extraction were studied. The method was developed for standard solutions of Pu, Th and U. A Quantulus liquid scintillation spectrometer was used for determination of alpha activity of these isotopes. It was found that using HDEHP in the first stage of the elaborated procedure and Aliquat 336 in the next, it is possible to separate Pu from the mixture of U and Th. Optimal values of measuring parameters such as a PSA value and a scintillation cocktail volume were established as well.

Opis:: In the present investigation, a comparative study was made on the effect of exogenous addition of sodium chloride on net leaf photosynthesis (CO2 uptake) in Aegiceras corniculatum (L.) Blanco, a dicotyledonous mangrove species. The net leaf photosynthesis of A. corniculatum was modified in the presence of sodium chloride, it may be called a preferential halophyte. Salinity is one of the most significant environmental challenges also abiotic constraints limiting plant productivity. A. corniculatum could tolerate up to 800 mM sodium chloride concentrations. The net leaf photosynthesis rate was increased with increasing NaCl salinity up to 400 mM. This concentration was found to be the optimum salinity level for this species. In conclusion, it may be inferred that sodium chloride promoted the photosynthesis concentrations upto optimum level of 400 mM in Aegiceras corniculatum (L.) Blanco. beyond 400 mM NaCl decreased the CO2 uptake. The maximum photosynthetic obtained at 400 mM NaCl on the l20th day.

Opis:: Fluorine and sodium chloride are common elements present in the water environment. According to WHO guidelines fluoride content in water cannot be not higher than 1.5 mF-/dm3. Elevated fluoride content was observed all over the world and it leads to many health issues. It can be removed with the usage of various methods (ion exchange, membrane processes, adsorption, precipitation). In this paper fluoride removal with nanofiltration usage was described. Tests were performed with the application of Amicon 86400 filtration cells. Two types of commercial nanofiltration membranes NP010P and NP030P (Microdyn Nadir) were used. Transmembrane pressure was established as 0.3 MPa. For lower fluoride concentrations (5 mgF-/dm3) NF process allowed to decrease fluoride content under level 1.5 mgF-/dm3. Removal efficiency decreased with increasing fluoride content. Membrane NP030P showed better separation properties. Sodium chloride influenced removal efficiency as well as fluoride adsorption on/in membranes during the process. According to obtained data, better hydraulic properties exhibited membrane NP010P. For both membranes decrease in permeate flux in comparison to pure water was noticed what was observed. Relative permeability was lowered even to 0.32.

Opis:: Modified PVC (M-PVC) material with suppressed migration and low glass transition temperature was prepared via click reaction of a monooctyl phthalate derivative. Chemical structure and composition of M-PVC were characterized by FT-IR, 1H NMR and element analysis. Thermal stability, glass transition temperature and migration stability of M-PVC were studied with TGA, DSC and migration tests, respectively. The study showed that M-PVC exhibited poor thermal stability, and low glass transition temperature of 66.0°C. No migration was found in distilled water, 10% (v/v) ethanol, 30% (w/v)acetic acid and petroleum ether. The PVC material is expected to preparing PVC products in the areas with high migration resistance requirement.

Opis:: To compare the effect of NaCl, CaCl2 and their combinations on germination and early seedling growth stages of Lycopersicum esculentum L., were studied under pot experiments 2008. Results indicated that significant increases were recorded in percentage of germination, seedling fresh and dry weights, seedling length, water content, catalase activity and photosynthetic pigments (chlorophyll a, b and total chlorophylls as well as carotenoids) under the low level concentration (20 mM) of NaCl or CaCl and their combination (1:1). On other hand increasing salt concentration in nutrient solution caused significant decrease in all of these parameters. The great reduction occurred under high salinity level of NaCl (50 mM). Meanwhile, peroxidase activity increased significantly with increasing salinity levels from 20 mM to 50 mM of both applied salinity types. Besides, peroxidase activity under NaCl salinity showed a marked increase followed by NaCl + CaCl2 (1:1) and CaCl2 at 50 mM.

Opis:: The effect of sodium chloride and calcium chloride on the fracture properties of whey protein concentrates (WPCs) and whey protein isolate (WPI) gels was investigated. Compression of gel samples was used to measure true shear stress at fracture and true shear strain at fracture. Investigated WPCs had such a great content of sodium and calcium ions, that they had a detrimental effect on shear stress values. Gels made from WPI and WPCs had similar salt- associated changes in shear stress at fracture, but shear strain responded in opposite way. Considering the content of calcium and sodium in concentrates, added NaCl and СаСІ2 influenced the fracture properties in the same way as WPI gels.
Celem pracy było przebadanie wpływu dodatku jonów sodowych i wapniowych na wartości rzeczywistego odkształcenia przy pęknięciu oraz rzeczywistego naprężenia stycznego przy pęknięciu żeli otrzymywanych z czterech różnych koncentratów białek serwatkowych i porównanie go z wpływem tych jonów na właściwości teksturalne żeli izolatu białek serwatkowych. Właściwości teksturalne żeli określono za pomocą ściskania, przy użyciu urządzenia Instron. Badania wykazały, iż analizowane koncentraty białek serwatkowych zawierały tak dużą ilość jonów sodowych i wapniowych (tabela 1), że działały one negatywnie na wartość rzeczywistego naprężenia stycznego przy pęknięciu (tabela 2 i 3). Wpływ jonów sodowych i wapniowych na wartość rzeczywistego naprężenia stycznego przy pęknięciu był podobny w odniesieniu do koncentratów i izolatu. Dodatek jonów sodowych powodował spadek wartości rzeczywistego odkształcenia przy pęknięciu a po osiągnięciu pewnego stężenia wzrost (tabela 4). Odwrotnie reagowały żele na dodatek jonów wapniowych (tabela 5). Biorąc pod uwagę zawartość jonów sodowych i wapniowych w badanych koncentratach, żele otrzymywane z tych koncentratów reagowały podobnie na dodatek jonów jak żele otrzymywane z izolatu. Zmiana właściwości teksturalnych żeli na skutek wzrostu stężenia jonów sodowych i wapniowych jest prawdopodobnie wywołana zmianą struktury: od żeli o drobnej strukturze przez mieszaną do ziarnistej.

Opis:: Introduction and aim. This study evaluated whether ethyl chloride spray had an analgesic effect on pain intensity caused by venepuncture compared to a placebo. Material and methods. A total of 339 patients were randomly divided into two groups: The group in which ethyl chloride spray was applied (n=212) and the placebo group (n=127). The analgesic efficacy of ethyl chloride spray was compared with the placebo group using the Visual Analog Scale (VAS). Results. When the analgesic efficacy of ethyl chloride spray was compared with the placebo group, the VAS score was 4 [interquartile range (IQR): 1.0] for the ethyl chloride spray group and 5 (IQR: 2.0) for the placebo group. The efficacy of ethyl chloride spray in reducing pain was statistically significant compared to the placebo (p<0.001). Conclusion. Ethyl chloride spray has analgesic activity in venepuncture. Therefore, this spray can be used at the emergency departments to reduce pain intensity in patients undergoing such interventions.
