Opis:
During the transmission of electromagnetic radiation through a medium containing water molecules, portions of the electromagnetic spectrum are absorbed by water molecules. This water absorption occurs preferentially at certain characteristic wavelengths while the balance of the spectrum is transmitted with minimal effects. This characteristic of water provides advantages but also some disadvantages in science and engineering applications. Especially in remote sensing applications, it may cause to produce incorrect information. So identification of behavior of electromagnetic wave in water is significantly important. Some of the studies based on electromagnetic wave behavior in water are bio-medical researches, sensors, transmitters, accumulators, organic-inorganic materials, and microwave ovens. In this paper, based on the water's absorption of electronic wave property, a plastic cup as half-full of water is imaged using near field microwave system. After being processed with 3D-DLL algorithm it is imaged as 3D with IRIS software. A robotic system is used for data collection process. Transmission and reflection measurements of system are done with N5230A network analyzer.

Opis:
Radiation is energy, and it is widely used in a variety of fields, especially in industry and medical science. In hospital, ionizing radiation like X-ray is an extensive exam that has been used to help physicians to have a view into the body, without having to make a medical application. Computed tomography scan uses ionizing radiation, and it is a nearly perfect diagnostic unit that allows the physician to see the picture of the human body. Computed tomography scan technology has progressed over the years, and it is an increasingly powerful and effective unit in the diagnostic radiology. Exposure to ionizing radiation is known to increase the risk of cancer. The aim of this study was to assess the radiation exposure received during computed tomography in a sample representative of the current state of practice in adult patients.

Opis:
Individual career planning plays a key role in achieving success, goals, and ideals in professional life. However, managing to accomplish such favorable results depends on the correct decisions of graduates to choose suitable job opportunities. Oceangoing watchkeeping officers, who are responsible for the management and administration of vessels at sea, have several job options which are differentiated by vessel type, such as; bulk carriers, chemical tankers, general cargo ships, and container ships, etc. This study aims to discuss the criteria that Turkish oceangoing watchkeeping officers take into consideration and the values they attribute to such criteria regarding their vessel type preference. The aim is to provide instructions to oceangoing watchkeeping officer candidates and academicians who are interested in these issues and related parties of maritime industry. Attribution values of the criteria are determined by means of Fuzzy Analytic Hierarchy Process (AHP) and the most preferred alternative vessel type is revealed through Fuzzy TOPSIS methodology. According to the study results, the most important factors are; revenue, perception of occupational health and safety, and labor work density. The most preferred ship type among alternatives is the oil tanker.

Opis:
Photodynamic therapy (PDT) is a minimally invasive treatment for cancer therapy. It can be administered in combination with other treatments such as chemotherapy, radiotherapy, and surgical excision. PDT involves a photosensitizing agent that is activated by exposure to a specific wavelength of light. PDT is a cold photochemical process, there is no tissue heating. In our study, we investigated whether different laser parameters with different concentrations of indocyanine green (ICG) have cytotoxic and anti-proliferative effects on neuroblastoma. Plates were divided groups as control, only ICG concentrations (25 and 50 μg/ml), only laser treatment I (50 J/cm²), only laser treatment II (100 J/cm²), 25 μg/ml ICG + laser treatment I and 25 μg/ml ICG + laser treatment II, 50 μg/ml ICG + laser treatment I and 50 μg/ml ICG + laser treatment II. Neuroblastoma cell lines were irradiated with an in-house developed diode laser system (λ=809 nm, 70 mW/cm², 50 & 100 J/cm²) in continuous wave operation mode after ICG application. Cell proliferation was measured by XTT assay after light irradiation. Cell proliferation was decreased in a dose-dependent manner in 25 and 50 μg/ml ICG concentrations when compared with control. The applied ICG concentrations (especially 50 μg/ml) had cytotoxic effects for neuroblastoma cell lines, SH-SY5Y. There was no difference between laser treatment groups (L 50 & 100 J/cm²). However, PDT groups (laser exposure with ICG) showed significant inhibition of cell viability (p<0.05). Additionally, laser exposure did not increase the well temperature above the incubation parameter. In conclusion, PDT has cytotoxic effects in neuroblastoma cell lines. Appropriate ICG dose - laser parameter combinations must be determined for each cell type. Different energy densities may cause different effects of PDT on inhibition of cell viability.

Opis:
Aluminum casting alloys are widely used in especially automotive, aerospace, and other industrial applications due to providing desired mechanical characteristics and their high specific strength properties. Along with the increase of application areas, the importance of recycling in aluminum alloys is also increasing. The amount of energy required for producing primary ingots is about ten times the amount of energy required for the production of recycled ingots. The large energy savings achieved by using the recycled ingots results in a significant reduction in the amount of greenhouse gas released to nature compared to primary ingot production. Production can be made by adding a certain amount of recycled ingot to the primary ingot so that the desired mechanical properties remain within the boundary conditions. In this study, by using the A356 alloy and chips with five different quantities (100% primary ingots, 30% recycled ingots + 70% primary ingots, 50% recycled ingots + 50% primary ingots, 70% recycled ingots + 30% primary ingots, 100% recycled ingots), the effect on mechanical properties has been examined and the maximum amount of chips that can be used in production has been determined. T6 heat treatment was applied to the samples obtained by the gravity casting method and the mechanical properties were compared depending on the amount of chips. Besides, microstructural examinations were carried out with optical microscopy techniques. As a result, it has been observed that while producing from primary ingots, adding 30% recycled ingot to the alloy composition improves the mechanical properties of the alloy such as yield strength and tensile strength to a certain extent. However, generally a downward pattern was observed with increasing recycled ingot amount.

Opis:
This paper presents an integrated evaluation approach for decision support enabling effective supplier selection and ordering processes in textile industry. The integrated evaluation method in this study includes two phases that consist of fuzzy AHP and goal programming approaches. Supplier evaluation and selection is a multi-criterion decision problem which includes both qualitative and quantitative factors. That’s why; firstly, linguistic variables expressed in trapezoidal fuzzy numbers are applied to assess weights and ratings of supplier selection criteria. Then a hierarchy multiple model based on fuzzy set theory is expressed and the geometric mean method of Buckley is used to aggregate pair wise comparisons. Finally, a goal programming model is built using the goals about coefficients of suppliers, total ordering cost, number of wrong deliveries, total delivery cost under the constraints of required minimum and maximum number of orderings and acceptable quality cost levels of each supplier and demand constraint of the product.

Opis:
Common juniper (Juniperus communis L.) is a valuable tree species in forestry and source of many natural products. However, natural regeneration of common juniper is difficult. To develop micropropagation procedures for this species callus induction and organogenesis experiments were carried out. It was found that genotype, gender, sampling time and different growth regulator-combinations had significant effects on callus induction in common juniper. Murashige and Skoog medium supplemented with Benzylaminopurine 0.1 mg l–1and indole-3-butyric acid at concentrations ranging between 0.5–4.0 mg l–1 were the best among the treatments to induce callus formation when spring buds were used as explant sources. In organogenesis experiments, the combination of 2 mg l–1 Benzylaminopurine and 1 mg l–1 2,4-Dichlorophenoxyacetic acid was found to be essential to bring about adventitious bud and shoot development from calli. Genotype, gender and sampling times had significant effects on promoting adventitious bud and shoot development. Although several experimental trials with 0.005, 0.03 and 0.05 mg l–1 indole-3-butyric acid and varying media compositions produced adventitious root like structures, none of these structures further developed into a true root system. However, the results of this pioneering study provide a foundation for further experiments concerning the in vitro regeneration of common juniper.

Opis:
In this work, nanostructured La-based materials were produced by chemical precipitation method onto Cladosporium cladosporioides fungal hyphae in aqueous solution. Materials were annealed at various temperatures between 100°C-600°C. The morphological properties of the synthesized material were studied by transmission electron microscopy. The surface area for sample annealed at 360°C was determined to be 85.64 m²/g using Brunauer-Emmett-Teller method. The nitrogen adsorption and desorption isotherm displayed a typical type-IV isotherm. Electrochemical properties of produced material were studied using cyclic voltammetry, long term charge/discharge analysis and impedance spectroscopy in the 0.5 M Na₂SO₄ electrolyte. The obtained nanostructured porous electrode exhibits quasi-rectangular shaped cyclic voltammetry curves with a specific capacitance of 2190 F/g at a scan rate of 2 mV/s.

Antimicrobial and antifungal polymers are gaining the attention of pharmaceutical makers and industrial design. Nanospheres-Polymers attached Platinum(II) / (IV) complexes have been synthesized to investigate antimicrobial activities. Firstly, nanospheres involving Schiff bases were synthesized from (aminomethyl) polystyrene and four substitute salicylaldehyde (2-hydroxy benzaldehyde, 5-fluoro-2-hydroxy benzaldehyde, 5-kloro-2-hydroxy benzaldehyde, 5-bromo-2-hydroxy benzaldehyde). Secondly, polymers attached Platinum(II) / (IV) complexes have been prepared by means of template method. The IR spectra show that the ligands act in a monovalent bidentate fashion all nanospheres involving Schiff bases. Square-planar and octahedral structures are proposed for Pt(II) and Pt(IV), respectively. All these substances have been examined for antibacterial activity against pathogenic strains, and antifungal activity. In particular, Pt(IV) complexes were more potent bactericides than all of the synthesized substances.

Opis:
Pressure injuries are a serious medical problem that both negatively affects the patient's quality of life and results in significant healthcare costs. In cases where a patient doesn’t receive appropriate treatment and care, death may result. Nurses play critical roles in the prevention, care, and treatment of pressure injuries as members of the healthcare team who closely monitor the health status of the patient. Today, the use of artificial intelligence is becoming more prevalent in healthcare, as in many other areas. Artificial intelligence is a method that aims to solve complex problems by using computers to mathematically simulate the way the brain works. In this article, we compile and share information about a deep learning model developed for the detection and classification of pressure injuries. Deep learning can operate on many types of data. Convolutional Neural Networks (CNN) prefer images because they can handle 2D arrays. In this case, the images, annotated according to the National Pressure Injury Advisory Panel pressure injury classification system, have been fed into a deep learning model using CNN. The developed CNN model has a 97% success in detecting and classifying pressure injuries, and as more images are collected and fed into the CNN, the prediction accuracy will increase. This deep learning model allows for the automatic detection and classification of pressure injuries, an indicator of health outcomes, at an early stage and for quick and accurate intervention. In this context, it is expected that the quality of nursing care will increase, the prevalence of pressure injury will decrease, and the economic burden of this health problem will decrease.
Odleżyny są problemem zdrowotnym, który negatywnie wpływa na jakość życia pacjenta i powoduje poważne koszty opieki. W przypadku braku odpowiedniego leczenia i opieki może to doprowadzić do śmierci pacjenta. Pielęgniarki odgrywają kluczową rolę w zapobieganiu, opiece i leczeniu odleżyn jako członkowie zespołu opieki zdrowotnej, którzy ściśle i stale monitorują stan zdrowia danej osoby. Obecnie w dziedzinie zdrowia, podobnie jak w wielu innych dziedzinach, coraz częściej wykorzystuje się sztuczną inteligencję. Sztuczna inteligencja jest metodą, która ma na celu rozwiązywanie złożonych problemów poprzez matematyczne symulowanie sposobu działania mózgu z wykorzystaniem komputerów. Niniejszy artykuł jest przeglądem zaprojektowanym w celu podzielenia się informacjami na temat modelu deep learning opracowanego do wykrywania i klasyfikacji odleżyn. Deep learning może działać na wielu typach danych. Konwolucyjne sieci neuronowe (ang. convolutional neural networks, CNN) preferują obrazy, ponieważ mogą obsługiwać macierze 2D. Obrazy, uporządkowane zgodnie z systemem klasyfikacji odleżyn według National Pressure Injury Advisory Panel (NPIAP), zostały przekształcone w "Deep Learning Model" z wykorzystaniem CNN. Opracowywany model CNN ma 97% skuteczności w wykrywaniu i klasyfikowaniu odleżyn, a im więcej obrazów zostanie zebranych i wykorzystanych w CNN, tym większe będzie prawdopodobieństwo trafnej prognozy. Ten model deep learning daje możliwość automatycznego wykrywania i klasyfikacji odleżyn, które są wskaźnikiem jakości zdrowia, na wczesnym etapie oraz dokładnej i szybkiej interwencji. W tym kontekście oczekuje się, że jakość opieki pielęgniarskiej wzrośnie, zmniejszy się częstość występowania odleżyn oraz obciążenie ekonomiczne związane z tym problemem zdrowotnym.

Scandium is one of the most important and strategic metals that can be recovered as a by-product from lateritic nickel-cobalt ores. In this research, different extractants were investigated to extract scandium from sulphate medium by using solvent extraction method. Generally, the organic extractants are classified as acidic, neutral and basic reagents. Thus, the aim of the present study was to compare scandium extraction efficiencies of some acidic, neutral and basic organic reagents. For this reason, Ionquest 290 (Bis(2,4,4-trimethylpenthyl) phosphonic acid), DEHPA (Di(2-ethylhexyl) phosphoric acid), Cyanex 272 ((Bis(2,4,4-trimethylpentyl) phosphinic acid) which are acidic organophosphorus compounds, Cyanex 923 (Trialkyl phosphine oxide), which is a neutral organophosphorus compound, and Primene JMT, a basic extractant, were used. The extraction efficiencies of these extractants were studied with respect to the extractant concentration at the same pH and O/A (organic/aqueous) phase ratio. As a result of this study, DEHPA and Primene JMT were found to have high scandium extraction efficiencies with lower impurity co-extractions at pH=0.55 with O/A phase ratio 1/1.

Purpose: To determine effect of working in the night shift system on nutritional status, anthropometric measurements, and risk of cardiovascular disease of health staff. Materials and Methods: This cross-sectional study was conducted between August-November 2017 at Samsun Ondokuz Mayıs University among 111 health staff. Data was collected with a questionnaire form including questions about demographic characteristics, nutritional status and anthropometric measurements. SPSS 21.0 statistical package program was used for statistical analysis and p<0.05 was considered statistically significant. Results: Based on waist circumference, 14.3% of men and 31.1% of women were at high risk, and based on waist/hip ratio, 4.8% of men and 33.3% of women were at risk of cardiovascular diseases. It has been shown that eating patterns are disrupted during shifts (89.2%), and 73.9% of participants cannot eat because their meals cool down during shifts. The difference in the numbers of main and snack meals consumed by health staff during the night shift was statistically significant (p<0.05). Body mass index, waist circumference, and hip circumference measurements decreased with increasing shift time. However, body mass index, waist circumference, and hip circumference increased as time spent in the profession increased. Conclusion: It was seen that night shift health staff are at risk of cardiovascular disease due to insufficient and unhealthy nutrition. It is clear that nutrition education programs are required for health staff working night shifts to reduce excess weight and obesity in this population.

Opis:
At the beginning of the work on the effects of global warming and climate change in the international area, there are efforts to reduce exhaust emissions. Because fossil fuel is depleting and exhaust emission gases emitted to the atmosphere are rising rapidly, energy efficiency is on the agenda in transportation. Therefore, automotive developers and scientists have undertaken new research in the automotive sector. Hybrid electric vehicle technology is one of the important studies that these researchers continue.
