Multifunctional living mulches for weeds control in organic apple orchards
Get PDFA trial assessing the suitability of multifunctional living mulch to maintain the soil and reduce weed infestation was carried out in an organic apple orchard in the years of 2019-2020. Perennial plants (Alchemilla vulgaris, Fragaria vesca, Mentha piperita) and annual crops (Tropaeolum majus and Cucurbita maxima) were grown in the in the rows of the apple trees. The weeds number and soil weeds coverage in tree rows were assessed. Regardless of the living mulch species utilized, the soil resulted to be mostly covered by perennial weed species such as: Equisetum arvense and Taraxacum officinale and annual species such as: Lamium purpureum, Stellaria media, Galinsoga parviflora, Capsella bursa-pastoris and Poa annua, which were the most common species also for the natural cover used as control. However, all living mulch species limited weed infestation and M. piperita, F. vesca and T. majus most strongly limited weeds growth. It is concluded that living mulch species can be a feasible practice to manage the soil on the tree rows in organic orchards.A trial assessing the suitability of multifunctional living mulch to maintain the soil and reduce weed infestation was carried out in an organic apple orchard in the years of 2019-2020.

How monochromatic and composed light affect the kale ‘Scarlet’ in its initial growth stage
Get PDFInterest in vegetables at their microgreen stage, especially those from the Brassicaceae family, has constantly grown due to their numerous health-promoting compounds. Brassica oleracea convar. acephala var. sabellica cv. Scarlet with purple leaf discolouration was used in the study. Four LED lighting treatments were applied: white light (control), monochromatic blue (430 nm), monochromatic red (660 nm) and purple, i.e., blue (30% in spectrum, 430 nm) mixed with red (70%, 620 nm and 660 nm in equal shares). Photosynthetic photon flux density (PPFD) was 100 µmol m–2 s–1, photoperiod – 16 h light. The purple light promoted the cotyledon growth but decreased the soluble sugars content. The blue light significantly enhanced the anthocyanins synthesis and the radical scavenging activity (RSA). While under white light, the highest concentration of free amino acids and the lowest RSA were observed. As regards the phenolic compounds and photosynthetic pigments content, the reaction of kale to white light was similar to those observed under the purple and red light conditions. The experiment discussed here is of great practical importance and reveals the need for more in-depth research

Physiochemical and mineral characterization of unexplored local grapes (Vitis vinifera L.) cultivars growing in Balochistan province, Pakistan
Get PDFGrapes (Vitis vinifera L.) are highly valuable crops enriched with minerals, vitamins, phenolics, and antioxidants required for daily human activities and to prevent cancer and cardiovascular diseases. The objective of this study was to elucidate the physicochemical and mineral evaluation of seven neglected local grape cultivars (‘Kishmish’, ‘Sra Kishmish’, ‘Askari’, ‘Sahibi’, ‘Haita’, ‘Sundar Khani’ and ‘Toran’) growing in Baluchistan, as it can help in future breeding, processing, and species conservation. Therefore, these cultivars were evaluated for different physical, biochemical, and availability of macro– and micro–mineral contents. In physical evaluation, the local cultivar ‘Haita’ showed maximum bunch length (19.72 cm) and bunch width (11.88 cm), while the highest bunch weight (527.33 g) was recorded in ‘Sahibi’. Similarly, significant differences were noted in biochemical traits, and maximum total soluble solids (24.76%) and titratable acidity (1.58%) were observed in ‘Sundar Khani’, while the highest vitamin C (26.17 mg 100 g–1), total sugars (30.26%) in Sundar Khani, and nonreducing sugars (8.79%) were recorded in ‘Haita’. The cultivars growing in Balochistan also showed variations in phenolics (113.79–346.50 mg GAE L–1) and antioxidants (85.77– 90.87%). Likewise, the concentrations of macro- and microelements were also highly variable in these cultivars. Overall, among these cultivars, ‘Toran’ performed better in the agroclimatic conditions of Balochistan, as it has high yield attributes such as berry length, width, and weight. Moreover, it was also enriched with total soluble solids, antioxidants, and calcium contents.Grapes (Vitis vinifera L.) are highly valuable crops enriched with minerals, vitamins, phenolics, and antioxidants required for daily human activities and to prevent cancer and cardiovascular diseases.

Foliar application of salicylic acid and proline to mitigate water deficit impact on purple coneflower (Echinacea purpurea (L.) Moench.)
Get PDFThe effects of foliar spraying of salicylic acid and proline on Echinacea purpurea under different soil moistures were investigated in the field conditions in the Southwest of Iran (2017–2019). The experiment treatments were the foliar application of salicylic acid (SA) and proline (both at 1 mM concentration) and 2 irrigation frequencies (6 and 10 every day based on 75–80% and 40–45% field capacity, respectively). The field experiment was set as a complete randomized block design with 3 replications. The volatile oils were analyzed using GC-FID and GC-MS. Germacrene D, p-cymene, β-caryophyllene, α-pinene, and β-bisabolene were detected as the main constituents. Deficit irrigation decreased the growth parameters of the plants; however, it improved the contents of the volatile oil and the major compounds of volatile oil. In addition, the maximum values of the volatile oil content and the main constituents of volatile oil were extracted from the plants under SA × water deficit treatment. In conclusion, the foliar spraying of SA under water deficit conditions was an applicable strategy to maintain and stabilize the growth and yield of E. purpurea.The effects of foliar spraying of salicylic acid and proline on Echinacea purpurea under different soil moistures were investigated in the field conditions in the Southwest of Iran (2017–2019).

Effects of different irrigation levels and varying doses of silicon applications on yield and some physiological parameters in lettuce cultivation
Get PDFThe study was repeated for two years to reduce the effects of water scarcity and drought stress in lettuce cultivation. The irrigation problem was created by applying 25% (I25), 50% (I50), 75% (I75) and 100% (I100) of the evaporation amounts formed in the class-A evaporation vessel. Si0 (0 kg ha–1), Si40 (40 kg ha–1), Si80 (80 kg ha–1) and Si120 (120 kg ha–1) silicon fertilisation was applied at four different doses. Head length, head diameter, head weight, root length, and leaf fresh and dry weight were measured in harvested plants. According to the data of 2020–2021, the best results in the effect of different doses of Si applications on plant head height, head diameter, head weight and root length at different irrigation levels were recorded from I75 × Si80, I75 × Si120, I100 × Si80, I100 × Si120 applications with the same severity level. While the Si40 dose gave good results at I75 and I100 irrigation levels, its effect decreased at I25 and I50 irrigation levels. At different irrigation levels where different doses of silicon were applied, I25 irrigation had the lowest leaf chlorophyll and relative moisture content and the most severe membrane damage, while I50 irrigation had a moderate effect. Leaf chlorophyll and moisture content increased, and membrane damage decreased in I75 × 80 kg ha–1 Si, I75 × 120 kg ha–1 Si, I100 × 80 kg ha–1 Si and I100 × 120 kg ha–1 Si applications. As a result, when the effects of the applications covering two years on plant growth and yield were evaluated, the most successful irrigation levels were determined as I75, I100, and the most successful silicon doses; were determined as 80 kg ha–1 and 120 kg ha–1.The study was repeated for two years to reduce the effects of water scarcity and drought stress in lettuce cultivation.

Combined effects of excess boron and salinity on the growth and ionic imbalance of lavandin (Lavandula × intermedia) plant
Get PDFGenerally, moderate to high salinity conditions and excess boron (B) occur together as limiting factors for plant growth in the soils of arid and semiarid regions. To determine the combined effect of excessive boron, salinity stress, or both, five different levels of B (0, 0.3, 0.6, 1.2, and 1.8 mM) and 80 mM sodium chloride (NaCl) were applied to lavandin plants grown in a greenhouse. The results showed that under nonsaline conditions, biomass production in shoots and roots and photosynthetic pigment contents (chlorophyll (Chl) a, b, and Chl a + b) decreased with exceptionally high B applications compared to the control. Moreover, the bioconcentration (BCF) of B (in shoots and roots), potassium (K) concentrations (in roots), K/sodium (Na) and calcium (Ca)/Na ratios (in shoots), and Ca/B ratios (in shoots and roots) decreased for all B applications compared to the control. In contrast, all B applications caused a remarkable increase in the carotenoid (Car)/Chl ratio, B concentrations (in shoots and roots), translocation (TF) of B, and net B accumulation compared to the control. In addition, under nonsaline conditions, concentrations of K (in shoots), Ca (in shoots and roots), and K/Na and Ca/Na ratios (in roots) were significantly increased by B applications compared with the control. Under saline conditions, significant decreases in Chl b, Chl a + b, BCF of B (in shoots and roots), and Ca/B ratio (in shoots) were observed in all B applications compared to the control. However, under saline conditions, B application caused significant increases in the Car/Chl ratio, TF of B, net B accumulation, and concentrations of B (in shoots and roots), K (in shoots), Ca, and Na (in shoots and roots) compared to the control. It was concluded that although it is not seen in the growth parameters, NaCl application could effectively alleviate the harmful effects of B toxicity in lavandin plants. Under saline conditions, notable decreases in the mean B concentration in shoots could be strong evidence for this hypothesis.Generally, moderate to high salinity conditions and excess boron (B) occur together as limiting factors for plant growth in the soils of arid and semiarid regions.

Modeling and simulation of electric vehicle batteries as an alternative energy storage system in smart grid applications
No full textSon yıllarda, teknolojik gelişmelerin hız kazanması ve içten yanmalı motorlu araçların çevresel etkileri nedeniyle, elektrikli araçların üretimi ve kullanımı giderek yaygınlaşmaktadır. Elektrikli araçların menzilinin artırılması için, daha büyük ve güçlü bataryalar tercih edilmektedir. Bu durum, araçların şebekeye enerji transferi yapabilmesi (vehicle to grid-V2G) için bir fırsat yaratmıştır. Bu tez çalışmasında, elektrikli araçların güneş ve rüzgar gibi yenilenebilir enerji kaynakları ile şarj edilerek, sıfır emisyon politikalarına hizmet etmesi için bir V2G konsepti sunulmuştur. Bu kapsamda, V2G konseptinin uygulanabilirliğinin incelenmesi için modelleme ve simülasyon çalışmaları yapılmıştır. Modelleme çalışmasında, elektrikli araç şarj istasyonlarının şebekeye optimum entegrasyonu sağlanmıştır. Sonrasında, hem elektrikli araçların şarj edilebilmesi hem de V2G konsepti ile araçtan şebekeye enerji aktarımının incelenmesi için Newton-Raphson temelli yeni bir matematiksel model önerilmiştir. Önerilen matematiksel modelin etkinliğini incelemek için, IEEE-33 test bara sistemi DigSilent yazılımında modellenmiştir. Bu matematiksel model ile elektrikli araç şarj istasyonları IEEE-33 test bara sistemine optimum entegre edilerek, şarj istasyonları üzerinden şebekeye aktarılan enerji transferinin etkinliği incelenmiştir (V2G konsepti). V2G konsepti, Normal, Poisson ve Rayleigh dağılım fonksiyonlarına göre simüle edilerek analiz edilmiştir. V2G simülasyonu ile sisteme aktarılan enerji miktarı hesap edilerek, V2G konseptinin hem şebekeye olan etkisi hem de çevresel etkileri sayısal çıktılara göre detaylı olarak sunulmuştur. Analiz sonucunda, Türkiye'deki tüm motorlu araçların elektrikli araçlara dönüştürüldüğü varsayılarak, araçların sadece %10'unun 10 saatlik V2G konseptine katılması durumunda, ortalama 59 GWh enerji aktarımı ve 50.000 ton CO2 emisyonunun azaltılabileceği öngörülmüştür.In recent years, the production and use of electric vehicles has become increasingly widespread due to the acceleration of technological developments and the environmental effects of internal combustion engine vehicles. Larger and more powerful batteries are preferred in order to increase the range of electric vehicles. This situation has generated an opportunity for vehicles to transfer energy to the grid (vehicle to grid-V2G). In this thesis, to serve zero emission policies, a V2G concept is presented for electric vehicles to be charged with renewable energy sources such as solar and wind. In this context, modeling and simulation studies are carried out to examine the applicability of the V2G concept. In the modeling study, optimum integration of electric vehicle charging stations into the grid is achieved. Afterwards, a new Newton-Raphson based mathematical model is proposed for both charging electric vehicles and examining the energy transfer from the vehicle to the grid with the V2G concept. To examine the effectiveness of the proposed mathematical model, the IEEE-33 test bus system is modeled in DigSilent software. With this mathematical model, electric vehicle charging stations are optimally integrated into the IEEE-33 test bus system and the efficiency of the energy transfer to the grid via the charging stations is investigated (V2G concept). The V2G concept is simulated and analyzed according to the Normal, Poisson and Rayleigh distribution functions. By calculating the amount of energy transferred to the system with V2G simulation, both the effect of the V2G concept on the grid and its environmental effects are presented in detail according to the numerical outputs. As a result of the analysis, assuming that all motor vehicles in Turkey are converted into electric vehicles, it is predicted that if only 10% of the vehicles participate in the 10-hour V2G concept, an average of 59 GWh energy transfer and 50,000 tons of CO2 emissions can be reduced
Investigation of Educational Game-Playing Skills of Preschool Teachers
No full textThis study aims to assess the educational game-playing skill levels of preschool teachers. The survey method, a quantitative research approach, was employed in this study. The study involved 61 preschool teachers from official kindergartens and kindergartens affiliated with the Diyarbakir Provincial Directorate of National Education during the 2022-2023 education period. As the data collection tool, the "Educational Game Playing Skill Observation Scale" was used. The data were analyzed using the SPSS statistical software. Independent Samples T-Test and One-Way ANOVA were utilized for the analyses while the LSD test, a Post-Hoc test, was employed to identify which group contributed to significant differences. It was discovered that preschool teachers' educational game-playing skill levels (x=100.47) were at satisfactory levels. In terms of the subscales of the observation scale, preschool teachers demonstrated very good skills in the preparation (x=3.60) and game phases (x=3.41), while their skills in the evaluation phase (x=2.66) were sufficient. There was no significant difference in the game skill levels of preschool teachers based on gender and educational level (p>0.05). The significant difference in skill levels among preschool teachers in the preparation phase, game phase, subscales, and evaluation phase subscale arises from participants with service periods between 21-31 years (p<0.05). In the study, the educational game-playing skills of preschool teachers are considered sufficient. The "preparation phase" and "game phase" exhibit very good levels of skill, while the "evaluation phase" is at satisfactory levels. © 2023 Authors. All rights reserved
Oral and post-transplantation infectious status in patients with hematopoietic stem cell transplants: A prospective observational study
No full textObjective. Infectious status may be life threatening in hematopoietic stem cell transplant (HSCT) recipients. The aim of this study was to evaluate the effect of oral status on infectious conditions during the neutropenic phase after HSCT.Study Design. Seventy patients with various hematologic malignancies were involved. Before HSCT, oral and periodontal exami-nation, including the number of teeth and decayed, missing, and filled teeth index (DMFT); visible plaque (%); bleeding on prob-ing (BOP [%]); clinical attachment level; and probing depth (PD) values were collected. Daily blood cultures were collected and analyzed in terms of infection-related parameters, including febrile neutropenia (FN), bacteremia, and C-reactive protein (CRP) during the neutropenic phase of HSCT.Results. Forty-two patients (60%) received autologous and 28 (40%) allogeneic HSCT. In both groups, patients without FN after HSCT had significantly lower DMFT index scores and fewer sites with PD >4 mm (P .05).Conclusions. The results suggest that periodontal status may not significantly impact the infection-related parameters in patients treated for HSCT. However, DMFT and the prevalence of sites with PD >4 mm may be involved in febrile neutropenia. (Oral Surg Oral Med Oral Pathol Oral Radiol 2023;135:242-248
