The issue presented in this article is the problem of specificity of the features which constitute the prohibited acts whose definitions contain the term condition under the influence and the term condition after consumption. One must take note of the fact that the lack of definition of clear quantitative limits of narcotic drugs in the content of the penalizing regulation does not make it unconstitutional. Although prima facie this situation may raise doubts related to the procedural safeguards, there is a number of important reasons for not providing specific ratios. However, it must be emphasized that both the doctrine and the jurisprudence point at the lack of possibility, or significant difficulty, to create an exhaustive list of narcotic drugs and their precise threshold ratios on which the criminality of individual behavior would depend.This article aims at providing general information on the subject to the broader public, and explaining reasons behind the status quo, rather than at solving the arising legal problems. The commitment embodies the intention to launch an irregular series of papers under a general (sub) title.

Citri Grandis Exocarpium (CGE) is a traditional Chinese medicine with a variety of biological activities. For efficient quality control of CGE, a simple, rapid, and accurate high-performance liquid chromatographic (HPLC) method was developed for simultaneous determination of four main compounds (naringin, rhoifolin, meranzin hydrate, and isoimperatorin) in this herb. These four compounds were separated on a C18 column by gradient elution with methanol and water. The flow rate was 1.0 mL•min−1, and the detection wavelength was 324 nm. The recoveries of the method ranged from 96.32% to 103.71%, and good linear relationships (r2 > 0.9998) over relative wide concentration ranges were obtained. Then this validated method was successfully applied to the analysis of nine batches of CGE samples.

The method for the determination of Sr microamounts in milk by flame atomic absorption spectrometry (FAAS) is suggested. The main characteristics for the determination of this metal have been optimized and investigated: optimum air and gas pressure; the influence of hydrochloric acid and an effect of time on the absorbance of strontium. The selectivity of the determination of strontium was also investigated. The limiting interfering Sr/M ratios (the determination error ±10%) have been estimated. The suggested technique is simple, fast, accurate and selective.

A highly sensitive indirect spectrophotometric redox method for the determination of osmium is reported on. The method is based on the oxidation of iodide by osmium (VI) and the spectrophotometric detection of the liberated iodine in the form of complex anion associate with 2-(4-diethylaminostyryl)-1,3,3-trimethyl-5-thiocyanato-3H-indolium chloride reagent. The appropriate reaction conditions have been established. The molar absorptivity is (0.2-1.2)·105 dm3/mol·cm at 589.5 nm wavelength. The absorbance of the coloured extracts obeys the Beer's law in the range to 7.6 mg/dm3 of Os(VI).

An effect of ultraviolet A (UVA) radiation on fluoxetine stability in solid phase with and without the presence of selected metal ions was studied using the chromatographic-densitometric method. Silica gel TLC F254 plates were used as the stationary phase and chloroform-methanol-ammonia 25% (45:4.5:0.5, v/v/v) as the mobile phase. The chromatograms were recorded densitometrically at a wavelength of λ = 260 nm.Both the concentration and kind of an ion have an effect on the photodegradation process. Kinetic studies demonstrated that fluoxetine photodegradation is the fastest in the presence of Cu(II) ions, decreases in the presence of Fe(III) and Fe(II) ions, and is the lowest in the presence of Al(III) ions. Under conditions established without the presence of metal ions, fluoxetine maintains photostability.The liquid chromatography-electrospray ionization/mass spectrometry (LC-ESI/MS) method was applied for the identification of decomposition products noting the presence of 3-phenyl-3-hydroxypropylamine and 4-trifluoromethylphenol.

The aim of the present paper is to review, describe and analyze determinant constructs, activated by the Italian variable demonstrative pronoun quello. The main corpus of the study consists on the discrimination and description of the morpho-syntactic peculiarities of the constructions in question, which can be identified with three structural types of determination (adjectival, prepositional and relative), in the interior of which atypical and more complex cases may be observed and give scope for uncertainty as to the typological classification. Further to this, the article offers a summary explanation and illustration of the difference between determinant and appositive sequences, as well as a concise description of the specific features of the determinant demonstrative and its sequences, relating to its referential, semantic, pragmatic and textual potential.

The relative permittivity of water decreases with increasing temperature. Therefore, it is likely that the soil water content determined with time domain reflectometry (TDR) is influenced by temperature. We derived a correction based on a refractive mixing model. Our field experiment on a peat soil and laboratory experiments on disturbed sand and loam samples showed that there exist significant temperature effects. The magnitude of these effects is a function of water content and temperature. Both the refractive mixing model-based correction and Ledieu’s correction compensated temperature effects reasonable well. We recommend Ledieu’s correction for its simplicity: only information of the soil temperature is needed to correct the measured water content. The model-based correction needs additional information of the TDR calibration function. Our laboratory experiments on disturbed clay samples however, did not show a temperature effect. We suggest that the electrical conductivity counteracts the temperature effects in clay.

Względna przenikalność dielektryczna wody zmniejsza się ze wzrostem temperatury. Zatem prawdopodobne jest, że wilgotność gleby określona metodą reflektometrii czasowej (TDR) jest uwarunkowana jej temperaturą. W niniejszej pracy podana została formuła korekcyjna oparta na modelu dielektryków złożonych. Przeprowadzone eksperymenty - połowy na glebie torfowej oraz laboratoryjny nu próbkach gleb piaszczystych i pylastych o niezachowanej strukturze - wykazały istnienie znacznego wpływu temperatury na wyniki pomiarów. Wielkość tego wpływu jest funkcją wilgotności i temperatury. Korekta z zastosowaniem modelu dielektryków złożonych oraz korekta Ledieu dobrze kompensowały wpływ temperatury. Zalecane jest stosowanie korekty wg Ledieu, ponieważ jest prostsza: do skorygowania zmierzonej wartości wilgotności wymagana jest tylko znajomość temperatury gleby. Korekta oparta na modelu dielektryków złożonych wymaga dodatkowej informacji o funkcji kalibracyjnej TDR. Przeprowadzone eksperymenty laboratoryjne na próbkach gleby ilastej o niezachowanej strukturze nie wykazały jednak wpływu temperatury. Sugerowane jest, że elektryczna konduktywność gleby maskuje wpływ temperatury na odczyt wilgotności metodą TDR dla gleby ilastej.

The analyzed organosilicon derivatives of electrostatically stabilized silanates belong to a group of pentacoordinated compounds. These derivatives are:1-(N-morpholiniomethyl)spirobi(1-sila-2,5-dioxacyclopentan-3-on)at,1-(N-morpholiniomethyl)spirobi(1-sila-2,5-dioxa-4-methylcyclopentan-3-on)at,1-(N-morpholiniomethyl)spirobi(1-sila-2,5-dioxa-4-(i-propyl)cyclopentan-3-on)at. In the course of the work, the extraction process and optimization of conditions for separation and determination of a mixture of electrostatically stabilized silanates were carried out using capillary isotachophoresis. Proper leading electrolytes were elaborated developed and the terminating electrolyte:4,4’-bis[(1-morpholiniomethyl)spirobi(1-sila-2,5-dioxacyclopentan-3-on)at] was proposed. The extraction process involved the use of three stationary phases: octadecyl, octyl and phenylpropyl. The highest recovery values, approx. 94%, were obtained on the phenylpropyl column. The optimum time of analysis by the isotachophoretic technique did not exceed 12 min. The developed method of separation and determination of electrostatically stabilized silanates expands the possibility of research on biological activity of this group of compounds in aqueous solutions and surface water vegetation.

A sensitive and convenient method for the determination of trace europium ions using an oscillating chemical reaction involving Ce(IV) - KBrO3 - acetone - oxalic acid - H2SO4 was proposed. The results indicated that the changes in oscillating period (T) was linearly proportional to the negative logarithmic concentration of Eu3+ (-log C) in the range of 1.41 × 10−8 ˜ 1.41 × 10−4 mol L−1 (r = 0.9982) with a detection limit of 1.04 × 10−9 mol L−1. The recoveries were limited to the range of 99.5% to 100.8%. Under the same conditions, other rare earth ions did not interfere with the determination of Eu3+. In addition, a perturbation mechanism was also discussed briefly. [...]

The fundamental information for selecting and designing the most efficient treatment method of hospital waste is obtained by means of waste composition analysis. Therefore, the aim of this study was to evaluate the physical and elemental composition of waste in four hospitals in Sivas, Turkey. The results should help us select and design proper waste disposal. During the study period it was estimated that the daily waste generation rate of four hospitals was 985 kg/day, projected to be 1267 kg/day in 2015. Furthermore, analysis indicated that the moisture content of wastes was 14,2 %. The four hospital wastes consist of 92% combustible wastes and 8% noncombustible wastes by mass. The combustible wastes constitute paper (16%), textiles (10,2%), cardboard (4%), plastics (41,2%) and food waste (17%). Since the ratio of combustible waste is high, the incineration method has been suggested as a proper disposal method.
