Układ bezpośredniej syntezy częstotliwości DDFS o obniżonym poborze mocy
PublicationW artykule zaprezentowano koncepcje układu bezpośredniej syntezy częstotliwości DDFS (ang. Direct Digital Frequency Synthesizer) opartego o aproksymację wielomianową. Układ zamiany fazy na sinus wykorzystuje jedynie analogowe funktory, tj. mnożniki oraz wzmacniacze operacyjne. Skutkuje to znaczącym obniżeniem poboru mocy oraz zmniejszeniem powierzchni układu w stosunku do rozwiązań wykorzystujących jedynie komponenty cyfrowe. Zastosowanie...

Place Attachment and Collective Action Tendency
PublicationThree studies were carried out to examine how place attachment and collective action tendency are related and what role self-expansion and social interactions play in this relationship. In the first study (N = 156) we found that a more active form of attachment – place discovered – is a significant predictor of tendency to engage in collective action in favor of one’s neighborhood. In the second study (N = 197), we focused on...

Fast, sensitive and reliable multi-residue method for routine determination of 34 pesticides from various chemical groups in water samples by using dispersive liquid – liquid microextraction coupled with gas chromatography – mass spectrometry
PublicationA simple and efficient dispersive liquid-liquid microextraction technique (DLLME) was developed by using a mixture of two solvents: 40 μL of tetrachlorethylene (extraction solvent) and 1.0 mL of methanol (disperser solvent), which was rapidly injected with a syringe into 10mL ofwater sample. Some important parameters affecting the extraction efficiency, such as type and volume of solvents, water sample volume, extraction time,...

Pestycydy fosforo- i azotoorganiczne w środowisku wodnym - zagrożenia i problemy analityczne
PublicationRosnące w bardzo szybkim tempie uprzemysłowienie świata wiąże się ze zużyciem ogromnych ilości substancji chemicznych, w tym pestycydów. Stanowią one grupę zanieczyszczeń środowiska bardzo często występujących w wodach powierzchniowych i gruntowych. Największe ich stężenie stwierdza się w okresie spływu wód roztopowych oraz wykonywania zabiegów agrochemicznych. W trakcie przebywania w środowisku wodnym pestycydy mogą ulegać różnym...

Green aspects of techniques for the determination of pesticides in fruits and vegetables
PublicationApplied all over the world, pesticides are some of the most dangerous pollutants of the environment because of their stability, mobility, their ability to accumulate in the environment and their consequent long-term adverse effects on living organisms in general and human health in particular. Their presence in the environment is a particular danger. It is therefore crucial to monitor pesticide residues using all available analytical...

Quechers sample preparation method variants for analysis of pesticide residues in fruits and vegetables
PublicationThis article describes the comparison of different versions of an easy, rapid and low-cost sample preparation approach for the determination of pesticide residues in fruits and vegetables by concurrent use of gas and liquid chromatography coupled to MS or ECD for detection. The sample preparation approach is known as QuEChERS, which stands for quick, easy, cheap, effective, rugged and safe. It is a combination of liquid-liquid...

Występowanie i zagrożenia związane ze stosowaniem pestycydów
PublicationIntensywna industrializacja świata sprawia, że do środowiska trafia coraz więcej niebezpiecznych związków, niezmiernie groźnych nie tylko dla fauny i flory, ale także dla człowieka. Klasycznym przykładem są pestycydy, opracowane i wprowadzone do powszechnego użycia po to by zabijać szkodniki, a jednocześnie stanowią jedną z najgroźniejszych grup związków chemicznych, z którymi człowiek ma do czynienia. W pracy przedstawiono charakterystykę...
