    Opis:
    Leaf area is linearly correlated with sapwood area in trees. The linearity of this relationship can be affected by some biotic and abiotic factors. Mistletoes are hemi parasitic plants that take up water and mineral nutrients from their hosts and affect host physiological responses. There is no conclusive evidence to show the effect of pine mistletoe (Viscum album ssp. austriacum) on leaf area and sapwood area relationship in Scots pine trees (Pinus sylvestris L.) at tree level. The aim of this study is to determine and quantify the effect of pine mistletoe on the structural variation of leaf area and sapwood area relationship at tree level in Scots pine. A total of 18 mistletoe infected and 12 uninfected Scots pine trees were destructively sampled. All needles and mistletoes were completely removed from sampled trees to determine needle and mistletoe characteristics, biomass and leaf area. Sapwood areas at breast height (BH) and at crown base height (CBH) were determined from wood discs taken from BH (1.3m) and CBH. Sapwood area was delineated by benzidine staining method. Pearson correlation, t-test and regression analyses were conducted to determine the relationship between sapwood area and needle-mistletoe leaf area relationships. The results indicated that both the relationships between sapwood area and leaf area in uninfected, and sapwood area and total leaf area (needle plus mistletoe leaf only) in infected trees were linear. However, the slope of regression equation for mistletoe infected trees was considerably lower when compared to the uninfected trees. As for the variation of the sapwood area along the stem below live crown, there was a slight difference between sapwood area at BH and CBH. The study showed also that mistletoe infection led to a significant reduction in needle size (length, width, area and weight) in Scots pine trees. Significant relationships were found between the sapwood area and leaf area in this study. The results of this study may help fill the gap in the knowledge concerning the impacts of pine mistletoe on the dynamics of Scots pine trees.

    Opis:
    Titanium dioxide $(TiO_2)$ thin films having different thicknesses of 220, 260, and 300 nm were deposited onto well-cleaned n-type silicon substrates by reactive DC magnetron sputtering and annealed in the range of 200-1000C in steps of 200°C. The effects of thermal annealing and thickness variation on the crystalline quality and surface morphology of the films were investigated by X-ray diffraction and atomic force microscopy measurements. It was found that the film quality and morphology depend on the annealing temperature. $TiO_2$ films exhibit a grain-like surface morphology. The root-mean-square roughness and grain size on the surface increase as a result of increasing film thickness.

    Opis:
    The effects of combined aminoethoxyvinylglycine (AVG) and modified atmosphere packaging (MAP) treatments on quality attributes of ‘0900 Ziraat’ sweet cherry fruit during the cold storage and shelf life were investigated in this study. Significantly lower weight loss and decay ratios were observed in all treatments throughout the cold storage period as compared to the control. A similar case was also observed referring to the shelf life. MAP treatments were found to be more effective in retarding the weight loss and decay ratio. Higher hue angle values were measured from AVG-treated fruit at harvest. Similarly, hue angle of AVG and MAP-treated fruit were also higher than for the control in all periods of cold storage and on the 7th and 21st day of shelf life. AVG-treated fruit had higher firmness values than the control at harvest. However, higher firmness values were measured from MAP-treated fruit during the cold storage and shelf life. At the end of cold storage, lower SSC and higher titratable acidity values were observed in AVG and MAP-treated fruit than in the control. AVG + MAP treatments yielded significantly higher vitamin C, total phenolics and antioxidant activity values than the control. Contrarily, the control fruit had significantly higher total monomeric anthocyanin than the other treatments. Based on current findings, it was concluded that combined AVG + MAP treatments could be used as a beneficial tool to maintain the quality of sweet cherry fruit throughout the cold storage and shelf life.

    Opis:
    The role of pre-harvest aminoethoxyvinylglycine (AVG) treatments on bioactive compounds, fruit ripening and quality of Japanese plum fruits (Prunus salicina Lindell cv. ‘Fortune’) were investigated in this study. Whole trees were sprayed once with an aqueous solution containing AVG (0, 100 and 200 mg L⁻¹) two weeks before the anticipated commercial harvest. Compared to control treatment, AVG applications retarded fruit ripening and peel red color formation of fortune plum fruits. Respiration rate and ethylene production in fruit were decreased by AVG applications. Respiration rate and ethylene production in control fruit were 57% and 60% higher than those in 200 mg L⁻¹ AVG-treated fruit at the last harvest date respectively. The total phenolics and total antioxidant activity were significantly reduced by AVG treatments. Antioxidant activities of fruits treated at the date with AVG were approximate 2 fold higher than those of control fruits at the last harvest date. The chlorogenic acid, caffeic acid, rutin and kaempferol contents decreased with both AVG concentrations at all harvest dates.
    Zbadano wpływ aminotoksywinyloglicyny (AVG) użytej przed zbiorem owoców śliwy japońskiej (Prunus salicina Lindell cv. ‘Fortune’) na ich składniki bioaktywne, dojrzewanie i jakość. Całe drzewa opryskano wodnym roztworem AVG (0, 100 i 200 mg l⁻¹ ) na dwa tygodnie przed spodziewanym zbiorem owoców. W porównaniu z wynikami z kombinacji kontrolnej, AVG opóźnił dojrzewanie owoców i wybarwienie ich skórki na czerwono. Preparat w stężeniu 200 mg∙l⁻¹ zastosowany w ostatni dzień zbioru spowodował także obniżenie intensywności oddychania owoców oraz wytwarzania przez nie etylenu (odpowiednio o 57 i 60% w porównaniu z owocami z kombinacji kontrolnej). Obniżyły się także całkowita zawartość fenoli i aktywność antyutleniająca. Ta ostatnia, w tym samym terminie użycia, była dwa razy wyższa niż u owoców z kombinacji kontrolnej. Zawartości kwasów chlorogenowego i kafeinowego, rutyny i kaempferolu obniżyły się przy zastosowaniu AVG w obu stężeniach i we wszystkich terminach zbioru owoców.

    Opis:
    Purpose: of this study is to address the issue of maintenance work in the accommodation sector. The development of the means of transport, the increase in income level and the increase in comfort level create a desire for people to travel more. In the travels to different cities, accommodation facilities such as hotels, holiday villages and apartments are used. Customer satisfaction is very important for the accommodation facilities. In order to ensure customer satisfaction, the services provided should not be interrupted and all machinery and equipment must be in working condition. To ensure this, it is very important to carry out maintenance work on the plants and devices. Therefore, the establishment of a maintenance management system in accommodation facilities is very important and it is necessary to carry out maintenance work. In this context, different maintenance methods are applied in accommodation facilities. In this study, maintenance of accommodation facilities is discussed. Design/methodology/approach: Within the scope of the study, maintenance and maintenance management in accommodation facilities are discussed. The maintenance principles of accommodation facilities are discussed in detail. The places where maintenance services are conducted in accommodation facilities and maintenance methods are discussed. Findings: This study shows that that the implementation of maintenance management system will increase customer satisfaction. It has been evaluated that maintenance can be successful not only by maintenance personnel but also with the participation of all plant employees. Research limitations/implications: In order to see the importance of maintenance in accommodation facilities, it will be appropriate to compare the hotels with the maintenance management system applied and the hotels that are not implemented in terms of customer satisfaction and maintenance expenses. For the future studies, the maintenance management system in hotels can be examined in detail. Practical implications: Expanding the maintenance management practices in accommodation facilities will increase the capacity utilization rate of the hotels and increase customer satisfaction. Originality/value: In the field of maintenance, detailed studies have been carried out in the manufacturing sector for a long time and have been examined in detail. However, work in this area is quite limited, especially in accommodation facilities and hotels. In this study, the subject of accommodation facilities and maintenance of hotels was discussed in detail.

    Opis:
    Productivity of plants is determined by multiple factors that directly affect one another, therefore yield variability may be high and difficult to predict. Most often, however, a lower crop yield is achieved in the notillage system than in the ploughing system. An exact field experiment was undertaken to determine the yield and chemical composition of pea seeds sown under conditions of: 1) conventional tillage – CT (shallow ploughing and harrowing after the harvest of previous crop, pre-winter ploughing in winter); 2) reduced tillage – RT (stubble cultivator after the harvest of previous crop); and 3) herbicide tillage – HT (only glyphosate after the harvest of previous crop). A cultivation unit was applied on all plots in the springtime. Pea seed yield was higher by 14.1% in the CT than in the RT system and by 50.5% than in the HT system. The CT system was increasing the plant number m–2, number of pods and seeds m–2, seed mass per plant, and 1000 seeds mass, compared to the other systems. Protein content of seeds was at a similar level in all analyzed tillage systems, but was affected by the study year. In turn, the mineral composition of seeds was determined by both tillage system and study year. The seeds harvested from CT plots contained more phosphorus and iron, those from RT plots – more calcium and zinc, whereas those from HT plots – more phytate-P, potassium, magnesium, and copper, compared to the seeds from the other plots.

    Opis:
    In this study, antioxidant activity (AA), total phenolics (TP), total flavonoids (TF), individual phenolic compounds (IPCs), vitamin C and six other fruit characteristics including weight loss, flesh firmness, color, soluble solids content (SSC), dry matter and titratable acidity (TA) of Caucasian whortleberry fruits (Vaccinium arctostaphylos L.) were determined at harvest and at a week postharvest intervals throughout the cold storage at 0°C for 4 weeks. Significant decreases were observed in fruit weight and flesh firmness during the cold storage period. While L* and chroma values decreased significantly, an increase was observed in hue angle values. Significant increases were observed in dry matter, but decreases were observed in SSC, TA and vitamin C contents. Caucasian whortleberry fruits had quite high polyphenol contents. Total phenolics (TP), total flavonoids (TF), antioxidant activity (AA) (according to ABTS+, DPPH· and FRAP antioxidant tests) and individual phenolic compounds (IPCs) significantly decreased throughout the cold storage. Chlorogenic acid was the major phenolic in Caucasian whortleberry fruits. It was concluded that Caucasian whortleberry fruits with high phenolic compound and flavonoid levels might serve a potential antioxidant source.
    Zbadano aktywność antyoksydacyjną (AA), całkowitą zawartość fenoli (TP), flawonoidów (TF), indywidualnych związków fenolowych (IPC), witaminy C oraz sześć innych cech, takich jak utrata wagi, zwartość miąższu, barwa, zawartość rozpuszczalnych substancji stałych (SSC), sucha masa oraz kwasowość (TA) owoców borówki kaukaskiej (Vaccinium arctostaphylos L.) podczas zbioru oraz z tygodniowymi przerwami po zbiorach w czasie całego okresu przechowywania w chłodni w temperaturze 0°C przez 4 tygodnie. Zaobserwowano istotny spadek masy owoców i zwartości miąższu podczas okresu przechowywania w chłodni. Wartości barwy zmniejszyły się istotnie, natomiast zaobserwowano wzrost wartości kąta odcienia. Zaobserwowano istotny wzrost suchej masy, ale spadek został zanotowany w zawartości SSC, TA oraz witaminy C. Owoce borówki kaukaskiej miały dość wysoką zawartość polifenoli. Całkowita zawartość fenoli (TP), flawonoidów (TF), aktywność antyoksydacyjna (AA) (według testów antyoksydacyjnych ABTS+, DPPH· i FRAP) oraz indywidualne związki fenolowe (IPC) istotnie zmniejszyły się w okresie przechowywania w chłodni. Kwas chlorogenowy był głównym fenolem w owocach borówki kaukaskiej. Wyciągnięto wniosek, że owoce borówki kaukaskiej o wysokim poziomie związków fenolowych i flawonoidów mogą służyć za potencjalne źródło antyoksydantów.

    Opis:
    Objectives. The purpose of this study was to collect data on self-reported sharps injuries to develop best practices to reduce them. Methods. Data on sharps injuries were collected for the period of January–October 2008 using Adverse Event Notification Forms already in use at Sema Hospital. Results. On average, 0.2% of all self-reported injuries were sharps injuries averaging one injury per month. Housekeeping staff sustained 64% of such injuries, nurses sustained 36% (5 incidents). Outpatient clinics experienced the most injuries at 28%, followed by the Internal Diseases Inpatient Unit with 21% and the Medical Waste Room with 14%. Injuries often occurred during contact with medical waste bags (28%) and while replacing full sharp-boxes (14%). Conclusion. In summary, reducing needle stick injuries is an important component of the occupational and patient safety program at Sema Hospital. The research described in this study allowed the hospital to provide targeted interventions to increase awareness of the risks of needle stick injuries and reduce such injuries. The steps used in the study can be used in any health care organization in the world to design a customized improvement plan to reduce risk and injury.
