Opis:
High carbonate content in soil negatively affect plant growth, because the availability of nutrients is restricted due to high pH. The present investigations were carried out to reveal possible alleviating effects of the exogenous root inoculation PGPRs on development and physiology of soilless-grown grapevines cultivated under alkaline stress in controlled glass house. pH of growth medium was increased from 7.5 to the values ranging from 7.9 (control) to 8.1 (A18) according to the bacterial inoculations by NaHCO3 supplementations. Bacteria inoculations did not result in statistically significant differences in pH values of growth media. The bacterial population density found in the rhizosphere of grapevines ranged from 6 × 108 CFU mL−1 (M-3) to 9 × 108 CFU mL−1 (Ca-637). The highest value of shoot thickness was obtained from Ca-637 (5.3 mm), followed by A18 (5.2 mm), while M3 did not significantly affected the shoot thickness. The greatest pruning residue per vine was obtained from A18 treatment (81.5 g), followed by Ca-637 (80.8 g) while the lowest value was determined in control. Vine yield was the greatest with A18 (1128 g) treatment and was followed by Ca 637 (1059 g). Considering the general observations, root inoculation of PGPRs A18 and Ca-637 may be recommended in enhancing bioremediation of alkali growth media.

Opis:
Turbidite sandstones deposited in rift settings are currently among the main targets of hydrocarbon exploration. However, the impact of style of sedimentation, cyclicity and diagenesis on reservoir quality of such sandstones is relatively poorly explored in the literature. The sedimentology, stratigraphic architecture, and diagenetic alterations of deep marine sandstones of the Mocene Nutaysh member of the Burqan Formation in the Midyan area (Saudi Arabia) are described based on number of measured sedimentologic sections, lithofacies identification in the field and laboratory studies. Three lithofacies types are here identified in the measured sections. These are from bottom to top: (1) “Lithofacies A” consisting of massive to thickly-bedded, coarse-to-very coarse-grained sandstone and conglomerates; (2) “Lithofacies B” consisting of well-bedded, coarse-to-medium-grained, well-sorted sandstone, and (3) “Lithofacies C” consisting of thin-bedded, fine to very fine-grained, current-rippled sandstone, bioturbated shaley siltstone and marl. The main diagenetic processes in the sandstones include the formation of grain-coating smectite and rhombic dolomite. Small amounts of cements include the formation of authigenic kaolinite and calcite. The reservoir quality is anticipated to have been preserved under the transformation of smectite to deep burial illite, which is believed to prevent formation of quartz cements.

Opis:
Architectural heritage can deteriorate for various reasons related to human interventions or natural causes. Especially buildings constructed with materials such as brick and stone are more likely to experience a few user and use changes in their lifetimes, which would result in interventions. While some of the changes can be prepared and controlled by experts, some can happen without necessary supervision due to the longterm transformations and social dynamics. However, in both cases, it can cause damage to a building. Especially when a structure is the heritage of a different era or a different culture, and society has already changed, even the interventions performed by experts can be inappropriate. In this study, the restoration and adaptive reuse project of the St. Vincent de Paul French School in Istanbul was analyzed to gain insight into the reasons for its deterioration and to determine the outcomes of the project.
Zabytki architektury mogą niszczeć z różnych powodów związanych z ludzką interwencją oraz czynnikami naturalnymi. Jest dość prawdopodobne, że budynki z cegły i kamienia przejdą w swoim życiu technicznym kilka zmian użytkownika oraz formy użytkowania, które to będą wiązały się z przebudowami. O ile niektóre zmiany mogą być przygotowane i nadzorowane przez ekspertów, o tyle inne mogą być przeprowadzone bez należytego nadzoru ze względu na długotrwałe przemiany i dynamikę społeczną. Niemniej w obu przypadkach zmiany te mogą doprowadzić do zniszczeń w budynku. Zwłaszcza zaś kiedy obiekt jest z innej epoki lub jest dziedzictwem innej kultury, a społeczeństwo zdążyło się już zmienić, nawet interwencje eksperckie mogą być niewłaściwe. W niniejszym badaniu przeanalizowano projekt zmiany sposobu użytkowania i przebudowy Szkoły Francuskiej im. św. Wincentego a Paulo w Stambule, aby zrozumieć przyczyny jej niszczenia oraz ustalić rezultat projektu.

Opis:
In this study, the effect of direct and recursive multi-step forecasting strategies on the short-term traffic flow forecast performance of the Long Short-Term Memory (LSTM) model is investigated. To increase the reliability of the results, analyses are carried out with various traffic flow data sets. In addition, databases are clustered using the k-means++ algorithm to reduce the number of experiments. Analyses are performed for different time periods. Thus, the contribution of strategies to LSTM was examined in detail. The results of the recursive based strategy performances are not satisfactory. However, different versions of the direct strategy performed better at different time periods. This research makes an important contribution to clarifying the compatibility of LSTM and forecasting strategies. Thus, more efficient traffic flow prediction models will be developed and systems such as Intelligent Transportation System (ITS) will work more efficiently. A practical implication for researchers that forecasting strategies should be selected based on time periods.

Introduction and aim. In the COVID-19 pandemic, which is a global threat, the awareness levels of intensive care nurses who meet all the care needs of patients can affect the quality of care. In this study, pandemic awareness and care behaviors of nurses who undertook the patient’s care needs in intensive care units were examined. Material and methods. The research was carried out with 317 nurses working critical care units of 12 hospitals in different provinces. “Nurse Characteristics Form”, “Pandemic Awareness Scale” and “Caring Behaviors Inventory-24” were used as data collection tools. Data were collected between March and August 2022 in the middle of the COVID-19 pandemic process using an online survey. Results. It was determined that 75.4% of the participants were female and the mean age was 25.56±4.49. Pandemic awareness scale score was 3.04±0.62 (0.11-3.67) and caring behaviors inventory score was 5.48±0.84 (1.00-6.00). A significant, positive, weak relationship was found between nurses’ pandemic awareness and all sub-dimensions of caring behaviors (p≤ 0.05). Conclusion. It was seen that the caring behaviors of nurses with high pandemic awareness were also positively affected. Although it was the first time they had experienced the pandemic, nurses were found to have good caring behaviors.

Opis:
Bismuth (Bi) doped zinc oxide (ZnO:Bi) thin films were prepared on glass substrates by sol-gel spin coating technique using homogeneous precursor solutions, and effects of Bi doping on the structural and optical properties of ZnO were investigated. The crystalline of ZnO films shifted from polycrystalline nature to amorphous nature with Bi doping. The plane stresses (σ) for hexagonal ZnO and ZnO:Bi crystals were calculated according to the biaxial strain model. The Urbach rule was studied as a function of non-thermal component to the disorder (defects in crystal structures) which is especially observed in the case of non-crystal semiconductors. The calculated Urbach energies and steepness parameters of undoped ZnO and ZnO:Bi films varied between 44.33 meV and 442.67 meV, and 58.3 × $10^{-2}$ and 5.8 × $10^{-2}$, respectively. The Urbach energies of the films increased with an increase in the Bi doping concentration and a great difference was observed for 7.0 mol.% doping. The band gap values of the films exhibited a fluctuated behavior as a result of doping effect.

Opis:
The possibility of construction disputes can be reduced, but they cannot be avoided due to the uncertain and risky nature of the building industry. Conflicts between construction parties often have very unfavourable effects, such as cost increases, poor construction quality and time extension in the schedule. Lots of studies have been carried out in order to try and avoid these disagreements. However, there are no common resolution tools or techniques due to the improving conditions and scope of contracted works. Advanced methods and dispute reasons should be fully monitored and updated for the applicable solutions. This paper discusses the current major constructional dispute reasons in Turkey. The questionnaire method was applied within the scope of this study. The questionnaire documents were randomly distributed to 80 contractors to analyse major dispute reasons in Turkey. Analysis of the questionnaire results indicates that the major current dispute causes are poor quality of performed works, delays in progress payments, inefficient site management, poorly written contracts and design mistakes.
Prawdopodobieństwo sporów budowlanych może zostać obniżone, jednakże nie można ich uniknąć, ze względu na niepewną i ryzykowną naturę przemysłu budowlanego. Konflikty pomiędzy stronami inwestycji często mają bardzo niekorzystny wpływ, taki jak wzrost kosztów, słaba jakość konstrukcji oraz wydłużenia czasowe w harmonogramie. W celu uniknięcia tych nieporozumień, przeprowadzono wiele badań. Jednakże, nie ma wspólnych narzędzi lub technik rozwiązywania tych problemów, ze względu na poprawiające się warunki oraz zakres prac budowlanych. Metody zaawansowane oraz powody sporów powinny być w pełni monitorowane i aktualizowane pod kątem stosownych rozwiązań. Niniejsza praca omawia obecne, główne powody sporów budowlanych w Turcji. W zakresie niniejszej pracy zastosowano metodę ankietowania.

The decolourization of Turquoise Blue HFG by immobilized cells of Lysinibacillus fusiformis B26 was investigated. Cells of L. fusiformis B26 were immobilized by entrapment in agar and calcium alginate matrices and attached in pumice particles. The effects of operational conditions (e.g., agar concentrations, cell concentrations, temperature, and inoculum amount) on microbial decolourization by immobilized cells were investigated. The results revealed that alginate was proven to be the best as exhibiting maximum decolourization (69.62%), followed by agar (55.55%) at 40°C. Pumice particles were the poorest. Optimum conditions for agar matrix were found: concentration was 3%, cell amount was 0.5 g and temperature was 40°C (55.55%). Ca-alginate beads were loaded with 0.5, 1.0 and 2.0 g of wet cell pellets and the highest colour removal activity was observed with 2.0 g of cell pellet at 40°C for alginate beads. Also, 0.5 and 1.0 g of pumice particles that were loaded with 0.25 and 0.5 g of cell pellets respectively were used and the results were found very similar to each other.

Opis:
The present study examines the current lifestyle of the last remaining Balkan Yörüks, a small and isolated group found within the Republic of Macedonia, and the modern representatives of an important portion of the Balkan nomads. The aim of this study was to document knowledge concerning local wild food plants and wild and cultivated medicinal plants, and to compare the Yörük ethnobotany with that of similar, more or less isolated ethnic groups occurring in the Balkan region (Macedonia, Bulgaria, Albania, and Turkey) in order to assess how cultural adaptation processes may have affected Yörük plant folklore. We conducted this study by means of detailed, semi-structured interviews with 48 key informants. Sixty-seven plant taxa were recorded from 55 genera, based on the compilation of more than 150 reports relating to medicinal, food, forage, ornamental, and dye plants, as well as some elements relating to animals and minerals. Our field study data show several major ethnic boundary markers that contribute to the homogeneity of the community and also distinguish it sufficiently from the surrounding society: (i) well-isolated locality; (ii) local dialect and endogamy; (iii) casual clothing worn by women; (iv) ceremonial jewelry: a necklace of cloves (Syzygium aromaticum); (v) Sempervivum marmoreum as an only ornamental plant which also has a medicinal use; and (vi) Mentha spicata as the dominant culinary herb, which has a medicinal use too. Comparison of the collected ethnobotanical data with that of similar, more or less isolated ethnic groups in the Balkan region shows that overlapping taxa include mainly plants whose fresh fruit are used; both nuts as well as edible greens. These plants are simultaneously used for medicinal purposes too, as home remedies, but in very different ways to other ethnic groups. Yörüks represent a remarkable cultural group in the Balkans. This community has nomadic traditions, but nowadays the people have a settled lifestyle. Traditional knowledge remains strong and is retained within a well-defined cultural boundary.

Introduction and aim. Although increasing vaccination rates among healthcare workers (HCWs) is crucial for protecting their own health and preventing the spread of infections to patients, vaccination rates remain low. The purpose of this study is to evaluate the knowledge, attitudes, and behavior of healthcare workers concerning seasonal influenza vaccination in a training and research hospital in Türkiye. Material and methods. This cross-sectional descriptive study was conducted among 364 healthcare workers working in a training and research hospital in Ankara, Türkiye. A face-to-face questionnaire was completed by selected participants that included questions about their sociodemographic characteristics, receiving seasonal influenza vaccination, reasons for not receiving vaccination, attitudes and behavior towards seasonal influenza vaccination recommendations for their surroundings, knowledge of who should get the vaccine, and their immunization history. Results. Among the participants, 58.5% stated that they had never received an influenza vaccination, 35.7% mentioned not receiving the regular influenza vaccination, and only 5.8% reported receiving the influenza vaccination regularly every year. Reasons for not getting vaccinated included not trusting the influenza vaccine’s protection (60.1%), not believing they are in the risk group (38.9%), and not finding a suitable time to get vaccinated (36.1%). A total of 57.1% of the healthcare workers recommended the influenza vaccine for their surroundings. Conclusion. Influenza vaccination rates among healthcare workers are quite low. To maximize influenza vaccine uptake, awareness programs are needed to correct the misconceptions health care workers have about the vaccine, and diverse strategies should be implemented to encourage them to get vaccinated, thereby promoting influenza vaccination.

Opis:
Hydroxyapatite is the main component of human hard tissues such as bones and teeth. Because it has a great biocompatibility with human organism, it is used as biomaterial with the purpose of form and repair hard tissues. Hydroxyapatite is formulated as $Ca_{10}(PO_4)_6(OH)_2$ and shows high stability under physiological conditions. In this study, biomimetic hydroxyapatite powder has been synthesized using by synthetic body fluids which has the same composition as human blood plasma. Moreover, the effect of different precursors on properties of synthesized powders has been investigated. For that purpose calcium nitrate tetrahydrate $[Ca(NO_3)_2 ·4H_2O]$, calcium chloride $[CaCl_2]$, calcium hydroxide $[Ca(OH)_2]$ and diammonium hydrogen phosphate $[(NH_4)_2HPO_4]$ were used as precursors. Mainly literature focused on the synthesis of hydroxyapatite powders was carried out using chemical method. However, in this study, the synthesis of hydroxyapatite powder is carried out using biomimetic method. Chemical structures of synthesized powders have been investigated by the Fourier transform infrared and X-ray diffraction methods. Results showed that synthesized powders have a pure hydroxyapatite structure. Surface area of the synthesized powders was measured by the Brunauer-Emmett-Teller method. Morphological structures have been characterized by using scanning electron microscopy. Furthermore, particle size of powders was calculated using the Brunauer-Emmett-Teller method. It was clearly seen that morphological properties of biomimetic hydroxyapatite have affected the use of different calcium precursors.

Opis:
Short-term traffic estimations have a significant influence in terms of effectively controlling vehicle traffic. In this study, short-term traffic forecasting models have been developed based on different approaches. Seasonal autoregressive integrated moving average (SARIMA), artificial bee colony (ABC) and differential evolution (DE) algorithms are the techniques used in the optimization of models, which have been developed by using observation data for the D-200 highway in Turkey. 80% of the data were used for training, with the remaining data used for testing. The performances of the models were illustrated with mean absolute errors (MAEs), mean absolute percentage errors (MAPEs), the coefficient of determination (R2) and the root-mean-square errors (RMSEs). It is understood that all the models provided consistent and useful results when the developed models were compared with the statistical results. In the models created separately for two lanes, the R2 values of the models were calculated to be approximately 92% for the right lane, which is generally used by heavy vehicles, and 88% for the left lane, which is used by less traffic. Based on the MAE and RMSE values, the model developed by the ABC algorithm gave the lowest error and showed more effective performance than the other approaches. Thus, the ABC model showed that it is appropriate for use on other highways in Turkey.

Opis:
Objectives: The aim of this 7-year follow-up study was to determine respiratory changes in dental technicians. Material and Methods: In our region, in the year 2005, 36 dental technicians were evaluated with a cross-sectional study on respiratory occupational diseases, and in 2012 we evaluated them again. Inclusion of information on respiratory symptoms and demographic features questionnaires was applied. Pulmonary function tests (PFT) were performed. Chest X-rays (CXR) were evaluated according to the ILO-2000 classification. For the comparisons of the technicians' findings in 2005 and 2012, data analyses were performed with the Wilcoxon test in addition to descriptive statistical procedures. Results: In 2012, 19 out of the 36 technicians continued to work in the same place, so we were able to evaluate their findings. The prevalence of respiratory symptoms in dental technician was as follows: dyspnea 7 (37%), cough 6 (32%), and phlegm 5 (26%). According to ILO classifications in 2005, among the 36 technicians, 5 (13.8%) had pneumoconiosis. At the end of 7 years, there were 9 pneumoconiosis cases among the 19 remaining technicians (47%). Thus, there was a statistically significant progression on the profusion of the radiologic findings (p < 0.005). Also there was a significant worsening on spirometric findings (p < 0.05). Conclusion: In dental technicians, a determination of both radiologic and functional progressions at the end of 7 years demonstrate that the primary and secondary preventive measures are necessary for these workplaces. Workplaces must be regularly controlled for worker health and hygiene.
