Development of an immunochromatographic assay based on carbon nanoparticles for the determination of the phytoregulator forchlorfenuron
2013
Rapid analytical methods enabling the determination of diverse targets are essential in a number of research areas, from clinical diagnostics to feed and food quality and safety. Herein, the development of a quantitative immunochromatographic assay for the detection of the synthetic phytoregulator forchlorfenuron (CPPU) is described. The competitive lateral flow immunoassay (LFIA) was based on the immobilization onto a nitrocellulose membrane of an ovalbumin-CPPU conjugate (test line) and on the use of an immunodetection ligand consisting of carbon nanoparticles labeled with an anti-CPPU monoclonal antibody through interaction with a secondary antibody. The presence of CPPU in horticultural…
Levels and Potential Health Hazards of Chlorinated Pesticidesin Surface Water Samples of Charsadda Area of Pakistan Using SPME-GC-ECD Technique
2021
In the present study, we determined the levels of chlorinated pesticide residues in surface water samples collected from the Charsadda district (KPK, Pakistan). SPME-GC-ECD with COMBI PAL CTC autosampler was used for extraction and analysis of 20 organochlorine pesticides in the collected water samples. For maximum efficiency of the SPME procedure, several parameters were studied, including the extraction and desorption time of the fiber, solution pH, agitation of samples, and stirring speed, etc. This method showed good liner response, with R2 values in the range of 0.9887 to 0.9999 for all pesticides. This method also provided good percent recoveries at 1 µg L−1 (87.5 to 106.0%) and at 2 …

How Do Young Adults Orchestrate Their Multiple Achievement-Related Goals? Associations of Achievement Goal Orientations With Identity Formation and G…
2016
Young adults strive for multiple achievement goals. Frameworks for achievement goal orientations, personal goals, and identity formation have emphasized the role of goal-specific exploration and commitment in the interpretation of goals. However, researchers have yet to combine these different perspectives in an empirical study. Therefore, to explore the processes involved in the selection of multiple goals, the present study investigated the associations of young adults’ achievement goal orientations (mastery-intrinsic, mastery-extrinsic, performance-approach, performance-avoidance, and work-avoidance orientations) with distinct styles of exploring and committing to goals, by considering d…
Italica (Seville, Spain): use of local marble in Augustan age
2010
This study concerns 51 marble finds made of “Cipollino verde” coming from the ancient city of Italica (north of the modern city of Santiponce, 9 km NW of Seville, Spain), the earliest Roman settlement in Spain, founded in 206 B.C. The aim of this work was to determine their provenance from Greek and Italian quarries or from local quarries worked in the Iberian Peninsula. Thin-section optical microscopy, X-ray powder diffraction, bulk rock chemistry and O, C and Sr stable isotope analyses were carried out. Results were compared with literature data on “Cipollino verde” marbles quarried in southern Euboea (Greece), Apuan Alps (Italy), Almería, Extremoz, Seville (Spain) and Évora (Portugal). T…
Darba samaksa, ar to saistīto nodokļu maksājumu analīze
2022
Temats ir aktuāls, jo kompensācija par darbu vienmēr ir bijusi viena no cilvēka pamatvērtībām, pašlaik darbaspēka stimulēšana ir viena no aktuālākajām problēmām darba attiecību jomā. Darbinieku algas sāka tieši būt atkarīgas no darbinieka intereses par darbu un motivāciju, lai būtu veiksmīgi izpildīti uzticētie uzdevumi un mērķi. Tam visam seko līdzi nodokļi, kuri ir jāieskaita valsts budžetā, ja tiek pieļautas kļūdas nodokļu piemērošanā, pastāv riski tikt sodītam, tādēļ darba devējam ir svarīgi izzināt nodokļu piemērošanas kārtību, kā arī izpētīt Latvijā aktuālo problēmu „aplokšņu algu” izmaksa uzņēmumos, noskaidrojot pastāvēšanas un izplatības iemeslus. Mērķis ir pamatojoties uz mācību li…
