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 the study, physico-mechanical properties [geometric mean diameter (Dg), sphericity, surface area, weight (W), bulk and fruit density, color, fruit removal force (FRF), puncture and compression force, puncture and compression deformation, friction coefficient] and biochemical attributes [pH, soluble solids content (SSC), titratable acidity (TA), vitamin C, total phenolics (TPs), total monomeric anthocyanin (TMA) and total antioxidant capacity (TAC)] of cherry laurel fruits (Prunus laurocerasus) and stones were investigated. Geometric mean diameter, surface area, fruit weight, bulk and fruit density significantly increased, but L*, a* and b* values significantly decreased with the progress of ripening. Fruit removal force decreased from 5.04 N to 3.09 N. On the other hand, W/FRF increased with the progress of harvest date. Static friction coefficient of fruits significantly increased over plywood and silicone surfaces and friction coefficients of stones increased over plywood, galvanized mild steel and silicone surfaces with the progress of harvest date. The pH, SSC, vitamin C, TPs, TMA and TAC (according to FRAP and TEAC assay) values significantly increased with the progress of ripening. It was concluded that fruit maturity stage at harvest had significant impact on physico-mechanical attributes and bioactive compounds of cherry laurel fruits.

Opis:
In the first part of this study hydroxyapatite was prepared synthetically through classical wet precipitation, using Ca(NO₃)₂·4H₂O (calcium nitrate tetrahydrate) as calcium source and HgN₂O4P as phosphate source. In the second part of the study HA compounds were prepared with different ratios (0.5, 1, 2, 5, 10 and 25 wt.%) of antibacterial materials like copper (Cu), silver (Ag) and europium (Eu), using the same wet precipitation method. The prepared pure HA material was utilized as the control group for comparison with Cu/Ag/Eu/HA composites. Studies of X-ray diffraction, FTIR spectroscopy, scanning electron microscopy, equipped with energy dispersive X-ray analysis were performed. The aim of this study was to investigate Cu/Ag/Eu/HA composites and the effect of metals on HA biomaterials, used as scaffold materials in bone disease treatment.

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 study was conducted in 2017 in the district of Sivas. In the study, 20 genotypes, which are considered to be different from each other, taking into account the fruit characteristics such as color and size and shape, were determined from the hawthorns that were naturally grown in the flora of Suşheri. At harvest time, the fruit, which would be adequate for pomological and biochemical measurements and analyzes, was harvested. According to the results of the measurements and analyzes in the study, fruit weight was found to vary between 0.68 g and 6.35 g, fruit width was between 10.52 and 29.48 mm and fruit length was between 11.40 and 20.67 mm. The highest firmness values were recorded with the genotype (G) 20 genotype, while the G4 had the lowest values in terms of the firmness values of the fruit flesh. While there are no significant differences between the pH values of the genotypes, the differences between the genotypes in terms of SSC, TA and vitamin C contents are quite significant. It has been found that there are significant differences between the genotypes in terms of total phenolic, total flavonoid and antioxidant activity. The total phenolic content ranged from 218.8 (G17) to 605.8 (G5 and G8) mg GAE kg⁻¹ f.w., while the lowest total flavonoid content was 21.58 (G 17) and the highest total flavonoid content was 67.75 (G9) mg GAE kg⁻¹ f.w. When the antioxidant activity was evaluated, the DPPH values were 1.08 (G17) – 15.43 (14) mmol TE kg⁻¹ f.w., the FRAP values were 15.43 (G16) – 47.23 (G8) mmol TE kg⁻¹ f.w. respectively.

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:
In tile manufacturing, α-Al₂O₃ is the main type of alumina used in ceramic body and glaze formulations. This raw material acts as an opacifier in porcelain tile bodies and as a matting agent in glazes. White fused alumina (WFA) is produced by fusing calcined alumina in an electric arc furnace under carefully controlled conditions. It is usually employed in floor tile glazes in order to increase their abrasion resistance. The aim of this study was to establish a better understanding of how alumina and white fused alumina addition affects the thermal behavior and aesthetic properties of wall and floor tile transparent glazes. It was shown that both alumina and fused alumina increased the softening temperatures of the standard glaze composition. Corund was the main detected phase in tile glazes incorporated with fused alumina. This result suggested that white fused alumina did not react with glassy phase to form any other crystalline phases. This result can be attributed to higher refractoriness of white fused alumina. Presence of anorthite and gahnite phases was, on the other hand, observed in the glazes with alumina addition. It was further shown that alumina was more effective in increasing opacity and reducing glossiness compared to white fused alumina.

Opis:
Zircon is the main opacifier in the ceramic sector, however its high cost limits its wide use and has led to the search of alternative materials. Nowadays, industrial whitening agents with different chemical formulas have started to be used in engobe, glaze and body compositions instead of zircon, to reduce raw material cost. Therefore, the purpose of this study is to investigate the possibility of usage of different industrial whitening agents as an alternative to zircon in opaque frit compositions. It was shown that, all of the studied whitening agents decreased the sintering and softening temperatures of the wall tile glazes. Although, alumina based whitening agents caused a glaze with transparent and boiling appearance, alumina with zircon and silica based whitening agents caused glazes with semi-opaque and glossy appearance. Even though none of the studied glazes has reached the standard whiteness indice, results suggest that alumina with zircon and silica based whitening agents could be a good candidate for zircon substitution in opaque frit compositions.

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.

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:
Nepheline-syenite is a fluxing agent used in sanitary ware, electrical porcelain and chinaware bodies, in order to reduce firing temperature and to increase the alkali level in the liquid glassy phase. Compared to pure feldspars, the advantages coming from the use of nepheline-syenite are: (i) the content of potassium and sodium is higher and (ii) the melting temperature is generally lower than that of potassium-feldspar, which always contains other phases, such as quartz, which shift the melting point to higher temperatures. The content of Al₂O₃ is high and the content of SiO₂ is lower in nepheline-syenite with respect to feldspars (considering that in feldspar Al₂O₃/SiO₂ is about 0.2, whereas in nepheline Al₂O₃/SiO₂ is 0.5). The aim of this study is to compare the influence of the nepheline-syenite and feldspars on the thermal behavior of the floor tile glazes. For this aim; several formulations were prepared with industrial raw materials. After applying the glazes on bodies; the compositions were fired in industrial floor tile kiln ( ≈1190°C, for 43 min). Thermal behaviors of glazes were measured by hot stage microscope and the crystalline phases were identified by X-ray diffraction. Color properties and glossiness were measured for comparing the aesthetic characteristics.

Opis:
Barium hexaferrite samples were prepared by mechanical alloying using the stoichiometric amounts of BaCO₃ and Fe₂O₃ precursors followed by heat treatment applied in the temperature range 700-1150°C. It was found that the high energy ball mill with a milling rate enabled to obtain powders with the finer particles at the reduced milling time mechanical alloying of the initial powders linked to the formation of barium hexaferrite phase. The exothermic reaction peaks corresponding to the formation of BaFe₁₂O₁₉ phase shift from 928°C to 793°C for the increased milling time up to 6 h. This was resulted in improved magnetic properties that the Mₛ value of the as-blended sample sintered at 800°C rised from 31.16 emu/g to 53.46 emu/g after milling for 6 h. The saturation magnetization and remanence values of the samples mechanically alloyed for 3 h and sintered at 1150°C also increased to 63.57 emu/g and 31.26 emu/g, respectively, more than for 800°C and 900°C. The increase in the annealing temperature favours the formation of BaFe₁₂O₁₉ phase in the samples.
