2016
Iwona Nowakowska | Renata Rasińska | Maria Danuta Głowacka
Introduction and objective Conditions of a healthy, friendly and safe work environment and proper work organisation increase self-efficacy and decrease or eliminate the factors causing the occurrence of burnout symptoms, all of which have a decisive impact on increasing the quality of work. The aim of the study was to analyse and assess the influence of factors of work environment and burnout syndrome on the self-efficacy of medical staff. Material and Methods The study comprised randomly selected professionally-active nurses working on hospital wards (N=405) on the area of two provinces in Poland. The study used the Generalized Self-Efficacy Scale, Copenhagen Burnout Inventory and a questionnaire concerning the factors that influence the process of work organisation at nursing positions in hospitals. Results Lower scores for self-efficacy resulted in a worse assessment of development opportunities and promotion prospects (r=-0.11), participation in the decision-making process (r=-0.11) and teamwork (r=-0.10). Lower self-efficacy contributed to the occurrence of burnout symptoms r∈[-0.19 – -0.17]. Conclusions Properly shaped and used organisational factors are stimulating for professional efficiency and effectiveness, and consequently, for the quality of nursing work. Negative assessment of the factors in the work environment contributes to the occurrence of burnout symptoms and decrease in self-efficacy. Nurses with lower self-efficacy more often experienced symptoms of burnout.

Bromus species are annual winter weeds from the Poaceae family which have become troublesome weeds of winter cereals. The herbicides propoxycarbazone and pyroxsulam are widely used for control of B. sterilis. The objective of this study was to determine the effect of different types of adjuvants and carriers on the efficacy of pyroxsulam and propoxycarbazone on B. sterilis. Small plot field trials were carried out in North Bohemia, Central Europe during 2011-2013. The tested carriers and adjuvants affected the efficacy of both herbicides and the seed production of B. sterilis. Urea ammonium nitrate was a less effective carrier than water (differences 5-30%). The most effective adjuvant was methylated seed oil (MSO), whose addition into the application water solution increased the herbicide efficacy of propoxycarbazone by 5-35%. Efficacy of the herbicide pyroxsulam was increased by adjuvant MSO by 10-30%. Nonionic surfactant increased herbicide efficacy only in 2013 (by 17%). Effect of organosilicone surfactant on the herbicide efficacy was negative (lower efficacy). Seed production of B. sterilis on untreated plots ranged between 20 000 and 50 000 seeds/m2 in experimental years. Seed production was the lowest on plots treated by the herbicide plus MSO (1300-4500 seed/m2).

The contact and ingestion activity and the potential of the insecticide spinosad for the control of sugar beet weevil were evaluated and compared with commercially used insecticides lambda-cyhalothrin and chlorpyriphos + cypermethrin. Results of three laboratory trials proved very good efficacy of spinosad applied at the dose of 72 g a.i./ha. Its efficacy was similar to chlorpyriphos + cypermethrin and significantly higher than that of lambda-cyhalothrin. Due to its favourable eco-toxicological properties and good ingestion activity, spinosad is a good candidate to be introduced in the integrated pest management strategy against beet weevil.

Rubio, L. | Alonso, C. | Pseudonymous, | Martinez, V. | Coderch, L.
The UV radiation of sunlight is known to damage human hair, causing fibre degradation. Gallic acid (GA) was used as an active principle because of its antioxidant properties, which confer protection against free radicals. Encapsulation technologies, such as polymer-based (micro- and nano-spheres, capsules) and lipid-based systems (liposomes, emulsions), have been used to enhance and prolong the effectiveness of active ingredients. In this study, GA loaded in PCL microspheres (GA-Micro) and GA encapsulated in PC liposomes (GA-Lipo) were prepared to study their effectiveness as antioxidants when applied to human hair compared with treatment with free GA. The antioxidant effects of these structures were measured by the Bradford colorimetric assay and the thiobarbituric acid (TBA) assay and fluorescence spectroscopy using 2,7-dichlorodihydrofluorescein (DCFH) as the fluorescent probe. The penetration of GA into hair depending on the vehicle was also evaluated. Higher penetration of GA was found in hair fibres treated with GA encapsulated vehicles. The results of the antioxidant studies showed that the efficacy of GA increased when it was encapsulated in liposomes and microspheres, as well as when the studies were performed immediately after antioxidant treatment. Moreover, GA that was loaded into microspheres retained its antioxidant efficacy for one and two months after treatment, indicating that the microspheres could preserve the antioxidant effect of GA. Moreover, the spectrofluorometric method was found to be the best method to evaluate the efficacy of GA embedded in different vehicles.

Bukhari, S.S.A.
Research was done on two important groups of nematodes plant parasitic nematodes, insect parasitic nematodes (Entomopathogenic nematodes). Among plant parasitic nematodes, root knot nematodes are the most economically important factor. RKN has a wide host range. They are damaging pest of many vegetable crops in Pakistan. Tomatoes are the most seriously affected by Meloidogyne incognita. The study were planned to investigate the effects of entomopathogenic nematodes (EPN) on the invasion, development and reproduction of Meloidogyne incognitaon tomato. In first experiment identify the different species of entomopathogenic nematodes on the basis of their infected color produce on the galleria. Further more check the efficacy of these species against the root knot nematode on tomato. Tomato plants were inoculated with different available species (S. asiaticum, S. glaseri, H. indicus, H. bacteriophora) of EPN at density 2000/pot in tomato plants at various times of applications (5 days before, at the same time, and after 5 days) of application of RKN were studied. Crop was harvested at 35 days to assess the reproduction (no. of galls, no. of egg masses, and no. of females) of M incognita in experimental plants. In the second experiment 4 species of EPN (2 species of Steinernema and 2 species of Heterorhabditis) were evaluated against invasion, development and reproduction of M. incognita (J2) sequentially. These 4 species of EPN mixed with RKN made treatments and inoculated with 1000 (J2s) of M. incognita and then EPN (2000/pot). Data were recorded after 7, 17 and 35 days far invasion, development and reproduction of M. incognita in experimental plants. Calculate the different stages of RKN population. In third experiment observed the protective and curative effect of EPN against RKN infection on tomato. EPN were applied @ 2000 juveniles before inoculation with 1000 (J2s) of M. incognita to observed the protective effect on the development of RKN. For curative effect EPN were applied after the inoculation of M. incognita. The crop was harvested after 35 days and data were recorded on the basis of reproduction variables of RKN.

The aim of the present study was to evaluate the efficacy of some chemical compounds to management rust disease on common bean under greenhouse and field conditions. In vitro , the effect of four chemical compounds, i.e. phosphoric acid at concentrations 0.3 and 0.6%, benzoic acid, Bion® (BTH), and pyrocatechol at concentrations 4 and 8 mM from each, as well as fungicide, Tilt 25%, 0.25 and 0.5 cm ³/l water on urediniospores germination of Uromyces appendiculatus was tested on water agar medium. All these compounds decreased the germination of urediniospores percentage. Under greenhouse and field experiments, application of these compounds led to decrease in disease incidence compared to the control treatments. Benzoic acid at 2015 growing seasons was the most effective in reduction of disease incidence more than the other compounds, whereas the disease incidence decreased from 59.92 to 21.43% and from 68.43 to 18.41% under greenhouse and field conditions, respectively.
