Opis:
All works of this article were conducted to investigate chemical composition and insecticidal and antimicrobial properties of Eucalyptus globulus and Rosmarinus officinalis essential oils isolated by hydro-distillation of its aerial parts. Analysis of the essential oils on the basis of gas chromatography and mass spectrometry (GC/FID and GC/MS) revealed the presence of 82 organic volatiles representing 98.63% of the total constituents of Eucalyptus globulus and the presence of 45 organic volatiles representing 98.53% of the total constituents of Rosmarinus officinalis. The major compounds for Eucalyptus globulus were estragole (28.14%), terpinolene (7.12%), 1,4-hexadiene-5-methyl-3-(1-methylethylidene) (7.01%), linalool (5.54%) and furfural (4.66%) and for Rosmarinus officinalis were (-)-camphor (31.16%) and ß-caryophyllene (18.55%), 3,4-dimethyl-(Z,Z)-2,4-Hexadiene (9.08%), ?-fenchene (4.67%), cis-verbenone (4.33%) and Bornyl acetate (3.4%). The efficacy of the two essential oils was evaluated on the insect pests Sitophilus granarius of wheat and was remarkable with lethal doses of 50% tending towards 1 µL·cm–3. The broth microdilution method as a complementary test was conducted to test the antimicrobial activity of the essential oil against: Staphylococcus aureus, Enterococcus faecium, Listeria monocytogenes, Bacillus subtilis, Escherichia coli, Yersinia enterocolitica, Pseudomonas aeruginosa and Candida albicans, further for the two oils of shows promising activity against all strains.

Opis:
Nutritional supplements play a role in promoting human protein synthesis, fitness recovery, and mental health protection. Pollen is considered a natural food with excellent nutritional value. The use of bee-gathered pollen as a nutritional supplement is now widespread around the world, and it is appreciated for its healing qualities. However, depending on the floral species and the region of origin, pollen has a wide range of nutritional value. It was found that clover pollen had the highest protein content (31.4 g/100 g DM), while the lowest content was observed in maize pollen (21.3%). Eucalyptus pollen had the highest lipid amount (9.49 g/100 g DM), while clover pollen had the lowest content (7.46 g/100 g). Phytochemical analysis showed that eucalyptus pollen occupied the highest total antioxidant activity (67.02%), followed by clover (58.25%) then maize (52.18%), whereas clover pollen had the highest phenolic content (1165 mg GAE/100 gm), compared with the other pollen varieties (949.4 to 1073 mg-GAE/100 gm). The contents of branched-chain amino acids were 29, 33.3, and 38.4 mg/g for maize, eucalyptus, and clover respectively, representing 17.87, 18.44, and 16.53% of total amino acids. The contents of total essential amino acids (EAAs) were 61.8, 73.0, and 83.5 mg/g for maize, eucalyptus, and clover pollen, respectively. Only eucalyptus pollen ultimately met the minimum requirements of EAAs for adults. In contrast, the other two types of pollen contained at least 3–4 limiting amounts of the essential amino acids leucine, lysine, phenylalanine, and valine. In conclusion, pollen is a good, affordable source of nutrients that can be utilized as beneficial dietary supplements for human health.

Opis:
The insecticidal effects of Eucalyptus dundasii Maiden essential oil was studied on the adults of the lesser grain borer, Rhyzopertha dominica (F.), and the saw-toothed grain beetle, Oryzaephilus surinamensis (L.). Essential oil was obtained by the hydro-distillation method and essential oil composition was analysed by GC-MS. Chemical analysis indicated that 1,8-cineole (54.15%), p-cymene (12.41%), α-thujene (11.37%), and E-caryophyllene (6.7%) were major constituents. For R. dominica and O. surinamensis, the LC50 of E. dundasii essential oil was 41.69 and 57.92 μl · l–1 of air, respectively. Increasing the concentration of the essential oil and the exposure time, increased mortality. The durability of fumigant toxicity on O. surinamensis adults was higher than on R. dominica adults and was statistically different. Based on the mean of the repellent indexes and the standard deviation, E. dundasii essence was repellent for both insects at 70, 140, and 280 μl · l–1 of air concentrations. Statistical analysis showed that Relative Growth Rate (RGR) in O. surinamensis was higher than in R. dominica, and the Relative Consumption Rate (RCR), the Efficiency of Conversion of Ingested food (ECI), and the Feeding Deterrence Index (FDI) in O. surinamensis was lower than in R. dominica. The many diverse bio-effects of E. dundasii essential oil confirmed that it is a good candidate for management of R. dominica and O. surinamensis.

Opis:
Nitrate assimilation in the plant cell is mainly regulated by the enzyme nitrate reductase (EC 1.6.6.1), which catalyzes the nitrate to nitrite reduction. Nitrate reductase activity (NRA) is measured at the major nitrate reduction site, which can be the root or shoot, depending on the species. The in vivo assay has often been used for NRA measurement, and protocol also usually varies with the species. The goals of this study were: (1) to identify the major nitrate reduction site in seedlings of two tree species, Eucalyptus urophylla and Khaya senegalensis, and (2) to optimize the in vivo nitrate reductase assay at the major nitrate reduction site in these species. Healthy seedlings aged 180 and 160 days, respectively, were selected for NRA measurement in fully expanded leaves and main root. After identifying the main nitrate reduction site of each species, the effects of variations in temperature, nitrate concentration and pH in the incubation medium were assessed. The results showed that the leaf and the root are the major nitrate reduction site of Eucalyptus urophylla and Khaya senegalensis, respectively. The optimal conditions for the in vivo assay in the leaf were 35 °C, $KNO_3$ 100 mM, and pH 7.0, whereas for the root they were 30 °C, $KNO_3$ 100 mM, and pH 7.5.

Opis:
The research compared the effect of peppermint oil (Mentha x piperita L. var. Officinalis) and Tasmanian blue gum (Eucalyptus globulus Labill.) oil and their doses on linear growth, biomass and sporulation of Fusarium culmorum (W.G.Sm.) Sacc., F. solani var. coeruleum (Sacc.) Booth and Sclerotinia sclerotiorum (Lib.) de Bary Schlecht. The research has shown that the fungistatic activity of ethereal oils under conditions in vitro depends on the kind of plant oil, its dose and fungus species. Among the tested pathogenic microorganisms, Sclerotinia sclerotiorum fungus is more sensitive to the presence of mint and eucalyptus oil. On the other hand, higher oil doses (0.8 and l .0 mm/cm3) reveal a better fungistatic effect on Fusarium fungi.
Badania laboratoryjne dotyczyły porównania wpływu olejku mięty pieprzowej (Mentha x piperita L. var. Officinalis) i olejku eukaliptusa gałkowego (Eucalyptus globulus Labill.) oraz ich dawek na wzrost liniowy, biomasę i zarodnikowanie Fusarium culmorum (W.G.Sm.) Sacc., F. solani var. coeruleum (Sacc.) Booth, Sclerotinia sclerotiorum (Lib.) de Bary. Z badań wynika, że aktywność fungistatyczna olejków eterycznych w warunkach in vitro zależy od rodzaju olejku roślinnego, jego dawki i gatunku grzyba. Z testowanych mikroorganizmów chorobotwórczych roślin, grzyb Sclerotinia sclerotiorum jest bardziej wrażliwy na obecność olejku miętowego i eukaliptusowego. Natomiast właściwości fungistatyczne w odniesieniu do grzybów z rodzaju Fusarium wykazują większe dawki olejków (0,8 i 1,0 mm/cm3).

Opis:
Despite the reputation earned by aromatic and medicinal plants of Algeria, the chemical constituents of Eucalyptus globulus essential oil (EGEO) of Blida origin has not previously been investigated. Thus, the present study has been conducted for the determination of chemical constituents and different physico-chemical properties of the EGEO. Chemical composition of the EGEO, grown in Algeria, was analysed by Gas Chromatography-Mass Spectrometry. The chemical components were identified on the basis of Retention Time and comparing with mass spectral database of standard compounds. Relative amounts of detected compounds were calculated on the basis of GC peak areas. Fresh leaves of E. globulus on steam distillation yielded 0.96 % (v/w) of essential oil whereas the analysis resulted in the identification of a total of 11 constituents, 1.8 cineole (85.8 %), α-pinene (7.2 %), and β-myrcene (1.5 %) being the main components. Other notable compounds identified in the oil were β-pinene, limonene, α-phellandrene, γ-terpinene, linalool, pinocarveol, terpinen-4-ol, and α-terpineol. The physical properties such as specific gravity, refractive index and optical rotation and the chemical properties such as saponification value, acid number and iodine number of the EGEO were examined. The oil extracted has been analyzed to have 1.4602 - 1.4623 refractive index value, 0.918 - 0.919 specific gravity (sp.gr.), +9 - +10 optical rotation that satisfy the standards stipulated by European Pharmacopeia. All the physical and chemical parameters were in the range indicated by the ISO standards. Our findings will help to access the quality of the Eucalyptus oil which is important in the production of high value essential oils that will help to improve the economic condition of the community as well as the nation.

W artykule przedstawiono wyniki badań nad oceną możliwości zafałszowania olejków eterycznych dostępnych na polskim rynku. Badania przeprowadzono za pomocą analizy z zakresu podczerwieni (FTIR) na próbkach olejków: drzewa herbacianego, eukaliptusowego, ylang-ylang i paczulowego. Otrzymane widma FTIR porównano z widmem oleju (tłuszczu) roślinnego. Na podstawie przeprowadzonej analizy stwierdzono, że olejek paczulowy zostały zafałszowany, natomiast w przypadku olejku ylang-ylang zastosowana metoda analityczna nie daje możliwości jednoznacznej informacji dotyczącej zafałszowania olejku.
The paper presents the results of investigation on the assessment of the possibility of adulteration of essential oils available on the Polish market. The research was carried out by means of an infrared (FTIR) analysis on samples of the following oils: tea tree, eucalyptus, ylang-ylang and patchouli. The obtained FTIR spectra were compared with that of vegetable oil (fat). Based on the analysis, it was found that the patchouli oil was adulterated. ATR-FTIR is not very useful method sufficiently reliable method to confirm adulteration of ylang-ylang oil.

Opis:
The suitability of Eucalyptus grandis bark and root for the pulp and paper industry was investigated. The bark of E. grandis was cooked using sodium borohydride (NaBH4) in the kraft process, while the root of E. grandis was cooked using the soda-anthraquinone (AQ) process. Four different charges (0.0, 0.3, 0.5, 0.7%) of NaBH 4 and AQ used as catalysts were added to the cooking liquor used in the processes. The chemical, mechanical and optical properties of the produced pulps were investigated and characterized. The yields, viscosity values, kappa numbers, as well as the brightness, tensile, burst and tear indices of the pulps were determined. The yield (RP: 39.1%, BP: 36.8%), viscosity value (RP: 897 cm 3/g, BP: 650 cm 3/g) and the kappa numbers (RP: 90, BP: 50) of the pulps produced from the root (RP) were higher than those of the pulps produced from bark (BP). The catalysts generally affected all the pulp properties, improving the properties of BP and RP. It was concluded that E. grandis bark and root can be suitable for the pulp and paper industry.

In the current study, the larvicidal activity of leaf essential oils from three eucalyptus species (Eucalyptus largiflorens Meull, Eucalyptus oleosa Meull, and Eucalyptus spathulata Hook) against American white moth, Hyphantria cunea Drury 1773 (Lepidoptera: Arctiidae), was investigated. Mortality was recorded daily for three days after treatment. Leaf disc bioassays revealed that all three oils had strong insecticidal activity on the experimental insects insofar as 50% lethal concentrations (LC50) for E. oleosa, E. spathulata, and E. largiflorens at 24 h exposure time were 0.36, 0.61, and 1.24%, respectively. The time needed to kill 50% (LT50) values were calculated as 9.09 h with E. largiflorens, 11.03 h with E. oleosa, and 13.03 h with E. spathulata at the highest concentrations (2.5% for E. largiflorens, 2% for E. oleosa, and 2.5% for E. spathulata). Based on probit analysis, an increase in the susceptibility of the insect was associated with an increase in the different concentrations of all oils and the increase in the time of exposure. The results of this study show that leaf essential oils of E. largiflorens, E. oleosa, and E. spathulata might be considered as a potent source for the production of fine natural larvicides.

Opis:
Two field experiments were established at the Agricultural Experimental Station of the National Research Centre at Nubaria, Beheira Governorate, Egypt to study the herbicidal potential of the leaf extract of Eucalyptus citriodora at 5, 10, 15, 20 and 25% compared to two hand hoeing, unweeded treatments and the chemical herbicides Bentazon + Clethodium, Bentazon + Fluazifop-P-butyl and Butralin on pea plants and associated weeds. The results indicated that two hand hoeing achieved the maximum weed depression as expressed by the dry matter of total weeds. The dry matter of total weeds decreased by 95.08 to 94.77% as compared with unweeded treatment 50 and 70 days after sowing (DAS) followed by Butraline (93.93–94.65%), Bentazon + Clethodium (93.26–94.07%), Bentazon + Fluazifop- -P-butyl (91.82–92.77%) and leaf extract of Eucalyptus at 25% (91.61–91.95%). Furthermore, the reduction in weed development was accompanied by enhanced pea growth and yield. The results revealed that two hand hoeing was the best treatment to increase plant height, shoot dry weight and SPAD value at 50 and 70 DAS. Also, two hand hoeing produced the maximum values of pod length and number of seeds/pod. The results also indicated that Bentazon + Clethodium treatment gave observable values [recorded 72.96% in pod yield (ton ⋅ fed.–1) over that of unweeded control] of number of pod/plant, weight of pod/plant, seed yield/fed and protein percentage. Also, the results revealed great increases in the growth of pea as well as yield due to treatment with E. citriodora dry leaf extract at 25%. [recorded 64.8% in in pod yield (ton ⋅ fed.–1) over that of unweeded control]. So, the results indicated using Bentazon + Clethodium as well as E. citriodora dry leaf extract at 25% to control weeds associated with pea plants. The authors suggested application of E. citriodora dry leaf extract at 25% in controlling weeds associated with pea plants as a safe method that avoids environmental contamination.

Opis:
In this paper we present our approach to the management of distributed systems based on semantic description of available resources. We use ontologies for a semantic description of the monitored system and other aspects of monitoring and management (such as metrics) and introduce a feedback loop on underlying infrastructure. Such an approach allows to automate monitoring and the ease the work of administrator. We introduce concepts behind a novel automatic management system, SAMM, developed within our research. We discuss the core mechanisms used in the system - the estimation of future measurements, approach to knowledge gathering, and the process of decision making. Then we provide some details on the architecture and implementation of SAMM.
Publikacja ta przedstawia nowe podejście do zagadnień monitorowania i zarządzania systemami rozproszonymi, wykorzystujące ontologiczny opis zasobów przez nie udostępnianych. Podejście to wykorzystuje ontologie do opisu semantycznego monitorowanego systemu, a także innych aspektów monitorowania i zarządzania nim (np. dostępne metryki) oraz wprowadza sprzężenie zwrotne na monitorowanej infrastrukturze. Pozwala to na automatyzację procesu monitorowania i zarządzania w celu ułatwienia pracy administratora. Publikacja opisuje także działanie nowatorskiego systemu SAMM, który powstał w wyniku badań. Przedstawione zostały również koncepcje dotyczące estymacji pomiarów, tworzenia baz wiedzy oraz procesu podejmowania decyzji. Artykuł opisuje zarówno architekturę SAMM-a, jak i szczegóły implementacyjne.

Opis:
The eucalyptus gall wasp, Leptocybe invasa (Hymenoptera: Eulophidae), is a new genus and species recorded for the first time in Duhok city, Kurdistan region, Iraq. L. invasa makes galls on petioles, leaf midribs and young branches of Eucalyptus camaldulensis saplings and trees. This galling eventually can lead to heavily injured saplings. The average number of galls was 37.23 gall/branch, and major infestation was on leaf midribs with an average of 19.35 galls.
Galasówka eukaliptusowa, Leptocybe invasa (Hymenoptera: Eulophidae), jest nowym rodzajem i gatunkiem zaobserwowanym po raz pierwszy w mieście Duhok leżącym w regionie Kurdystanu w Iraku. L. invasa powoduje powstawanie galasów na ogonkach i nerwach liściowych oraz na młodych gałęziach drzew Eucalyptus camaldulensis. Powstawanie galasów może ostatecznie doprowadzić do poważnego uszkodzenia. Średnia liczba galasów wynosiła 37,23 na gałąź, a porażenie występowało głównie na nerwach liścia, gdzie średnia liczba galasów wynosiła 19,35.
