Aşır Yüksel Kaya
Developments in Geographic Information Systems and Remote Sensing (RS) technologies and innovative approaches emerging in deep learning (DL) supported analysis methods have an important place in disaster research as in every field. Convolutional neural networks such as Mask RCNN, U-NET, one of the deep learning methods for disaster damage impact assessment and classification, have started to show successful results. However, high-resolution geospatial imagery and drones provide faster and more accurate detection of structural damage. In this study, damaged building detection was performed using Göktürk-1 satellite images from 6 February 2023 using Mask-RCNN architecture. In this study, deep learning methods were used to detect the collapsed buildings in the city of Malatya during the 6 February 2023 earthquakes. The study aims to emphasize the significance of GIS and remote sensing for the timely and efficient evaluation of building damage after a disaster. Considering this, high quality images of Malatya city before and after the earthquake were analyzed and data sets were created by masking using Mask RCNN deep learning method through ArcGIS Pro 3.4.0 software. According to the results of the research, it quickly detected damaged buildings with an accuracy rate of 70% according to satellite images after the earthquake. As a result, GIS and deep learning models were used to detect and map the initial damage after the earthquake.

Bu çalışmada, portakal dilimlerinin kalite özellikleri üzerine farklı sıcaklık (60, 70 ve 80°C) ve mutlak basınç (15 ve 30 kPa) kombinasyonlarında gerçekleştirilen vakumlu kurutma (VK) işlemlerinde mikrodalga ön işleminin (90 W, 30 dk) etkileri incelenmiştir. Vakumlu kurutma işlemleri, aynı sıcaklık ve basınç koşullarında mikrodalga ön işlemi uygulanarak (MDVK) ve uygulanmadan (VK) gerçekleştirilmiştir. Çalışma kapsamında, polifenolik bileşikler (vanilik asit, klorojenik asit, gallik asit, sinapik asit, o-kumarik asit, epikateşin, hesperidin ve naringenin) analiz edilmiştir. Ek olarak, renk parametreleri (L*, a*, b* ve ΔE), esmerleşme indeksi (BI) ve beyazlatma indeksi (WI) gibi görsel kalite özellikleri de değerlendirilmiştir. Taze portakalların başlangıçta sahip olduğu renk özellikleri ve fenolik bileşen seviyelerini kurutma işlemi sonucunda en iyi koruyan vakumlu kurutma koşulları 80°C sıcaklık ve 15 kPa mutlak basınç olmuştur. Temel bileşen analizi (PCA) ve hiyerarşik kümeleme analizi (HCA) kullanılarak, kurutma koşullarının renk ve polifenolik bileşen profilleri üzerindeki etkileri kapsamlı bir şekilde değerlendirilmiştir. Bu analizler, ürün kalitesine ilişkin kimyasal ve polifenolik profillerin ayrıştırılmasına olanak sağlamıştır.

The aim of the present study was to determine the the effects of carazolol injection during mating following progestagen + eCG administration on conception rate in breeding season Lacaune ewes. Sixty-two Lacaune ewes were used in the study. On day 0, an intravaginal sponge containing 20 mg flugestone acetate was inserted and left in place for 10 days. On day 10, the sponges were removed, and each ewe received an intramuscular injection of eCG at a dose of 480 IU. Ewes in estrus were mated with a proven rams (ewe:ram ratio of 5:1). Fifty-nine mated ewes were randomly assigned into two groups: control and treatment. In the carazolol group (n = 30), ewes received an intramuscular injection of carazolol (0.01 mg/kg; Simpanorm, Fatro, Italy) on the day of estrus, post-mating. In the control group (n = 29), ewes were not administered any treatment. Pregnancy diagnosis was conducted in all ewes on days 30 and 60 post-mating using transabdominal ultrasonography with a Hitachi EUB-405 device equipped with a 3.5 MHz convex probe. The estrus rate, conception rate, total pregnancy rate, and early fetal death rate were evaluated across all groups. The study results indicated no statistically significant differences between the control group and the carazolol group regarding conception rates (62.1% vs. 66.7%) and total pregnancy rates (79.3% vs. 83.3%). In addition, as a result of repeated ultrasound examinations, no early fetal death was found in the study. In conclusion, carazolol injection during mating following progestagen + eCG administration did not increase on fertility in breeding season Lacaune ewes.

The addition of dietary fibres (DF) obtained from by-products into bread is an attractive way to enhance consumers’ fibre consumption while simultaneously reducing waste from by-products. This study aimed to examine the viability of replacing kohlrabi peel powder (KPP) into white bread at levels ranging from 0% to 12%. The technological and nutritional characteristics of white breads were evaluated, and sensory analysis was conducted. The specific volume values of the samples ranged from 1.486 to 1.861 mL/g. The findings showed that the specific volume of the white bread samples decreased when KPP was used at concentrations higher than 3%. The sample coded N4 (9%) exhibited higher moisture levels in both the crumb and crust, compared to the all bread samples (p˂0.05). The nutritional features of the bread samples varied as follows: ash content ranged from 0.573% to 0.588%, protein from 6.460% to 7.998%, fat from 3.200% to 4.200%, total DF from 0.250% to 3.214%, total carbohydrate content from 51.963% to 69.272%, and energy levels from 211.7 to 324.0 kcal. The sample coded N3 (6%) was approved by the panelists, however the other samples with a greater quantity of KBB were not favored. SEM images showed the gluten structure in the enriched bread samples coded N2, N3 and N4 were constituted by fibrous components that established a more open network. The study’s results indicated that elevated amounts of KPP might enhance the DF content of white bread; however, consumers do not favor higher fibre content in the bread samples. Utilization of 6% KPP could enhance the technological, nutritional, and sensory characteristics of white bread.
Afficher plus [+] Moins [-]The Impact of PEG-induced Drought Stress on Seed Germination and Initial Seedling Growth of Lupinus albus L. Texte intégral

Ramazan Beyaz | Veli Vural Uslu
Drought is regarded as one of the most significant abiotic constraints to agricultural crop output worldwide. Drought in the spring and early summer, which coincides with important reproductive stages, severely limits lupin yield in Mediterranean climate zones. The purpose of this study was to determine how different drought treatments affected seed germination and initial seedling growth in Lupinus albus L. (white or field lupin). Seed germination parameters and initial seedling growth traits were tested against five levels of drought stress induced with Polyethylene glycol-6000 (PEG6000) at concentrations of 0, 4, 8, 12, and 16%. An experiment with four replications was conducted using a completely randomized design. The results revealed that the negative effect of drought stress started at 4% (-0.03 MPa or -0.3 bar) treatment for the initial seedling growth stage; whereas, it started at 12% (-0.2 MPa or -2 bar) treatment for the germination stage. Therefore, it was determined that L. albus was more sensitive to drought stress at the initial seedling growth stage than at the germination stage. However, it was observed that the growth parameters were more sensitive in shoot growth than in root growth to drought stress. There will be a sharp loss of yield in soils with levels of drought stress imposed by 12% PEG6000 (-0.2 MPa-moderate drought-) and beyond. Therefore, it is likely that L. albus has low drought tolerance.

According to the purpose of use, the buildings are named with names such as residences, commercial buildings, health buildings, social structures, educational buildings, sports buildings, worship buildings, etc., and classifications are made for agricultural buildings as rural structures, animal-plant production structures and protection-storage structures. It has become important to determine the type and thickness of the insulation material that will provide the most economic benefit to reduce the energy costs consumed by reducing thermal losses/gains in all building types and to reduce the damage caused by waste gases to people, the environment and especially agricultural production. In order to reduce thermal losses and gains in building exterior walls and to reduce heating-cooling costs, it has become important to determine the type and thickness of insulation material that will provide the most economic benefit. In this study, optimum insulation thicknesses, annual savings, payback period and reduction in CO2 emissions were calculated for heating and heating-cooling application in Tokat. DD method and LCA method were used for thermal and economic analysis. XPS and RW were chosen as insulation materials according to two different wall types, natural gas for heating and electricity for cooling as energy sources. The payback period and CO2 emission were calculated with a lower value in the use of XPS insulation material than in RW insulation material. For this reason, it has been determined that it is more appropriate to prefer XPS insulation material in terms of economy and environment only in heating and heating-cooling application.

Zelalem Yadelew
The availability of high-yielding varieties adapted to diverse agro-ecologies and production systems, preferred by farmers and consumers, is the key factor limiting productivity. Farmers access seeds of different quality levels from various seed systems. Studies on seed systems and rates in relation to yield and yield traits of bread wheat varieties under irrigation are limited. Therefore, an experiment was conducted in 2021 in Northwestern Ethiopia to improve the productivity of bread wheat (Triticum aestivum L.) varieties through suitable seed rates and systems under irrigation. The experiment was conducted using a randomized complete block design in a factorial arrangement of two varieties (Kakaba and Ogolcho), three seed systems (formal, intermediate and informal), and three seed rates (125, 150, and 175 kg ha-1) in three replications. SAS software was used for analysis. The results showed that the seed system and variety interaction had a significant effect (P < 0.05) on productive tiller numbers, days to 50% heading, kernel numbers per spike, and plant height. Additionally, the productive tiller numbers and days to 50% heading were significantly (P < 0.05) influenced by the interaction of variety with seed rate. However, the main effects of seed system, seed rate, and variety alone had a significant (P < 0.05) impact on physiological maturity, 1000-seed weight, kernel length, grain yield, biomass yield, and harvest index. The highest grain yields were obtained from the following main factors: seed system (intermediate (4.52 t ha-1); seed rate (150 kg ha-1 (4.71 t ha-1)); and variety (Kakaba (4.47 t ha-1)), which exceeded the average yield in irrigation (4.4 t ha-1). It is necessary to conduct experiments involving a greater number of seed rates and varieties over multiple cropping seasons and locations and sowing dates to strengthen the results.

Over the years, more than 3336 rice genotypes were introduced into Ethiopia from different countries and evaluated for diseases reaction and agronomic traits. However, morphological characteristics and relationships were not well investigated among genotypes. Hence, the objective of this study was to characterize 100 rice genotypes morphologically for better identification and to classify genotypes relationships. The experiment was done using triple lattice design with 10×10 in 2021/22 main cropping season. Twenty-five qualitative morphological traits were used to characterize and 13 quantitative traits were used to categorize relationships of the studied rice genotypes. The Shannon Weaver diversity index of qualitative traits were varied from 0 to 1. Moreover, based on quantitative traits the studied rain fed rice genotypes were grouped into four distinct clusters and four principal components with Eigen value >1 were contributed 78.99% of the total variation. We recommend crossing cluster I with IV genotypes to get early-maturing besides moderate grain yield variety for short rainfall season areas. And cross cluster III with IV genotypes to get medium matured, high filled spikelet per panicle, augmented harvest index, biomass and grain yield variety for long rainfall season areas.

Tephritid fruit flies (Diptera: Tephritidae) are the major damaging pest for the Watermelon (Citrullus lanatus (Thumb.) Matsum. & Nakai). The quality as well as quantity of watermelon is greatly affected by fruit fly. This study was conducted to test the efficacy of different traps and baits for fruit fly control. The experiment was designed in a randomized complete block design containing eight treatments and three replications. Each treatment, 0.2 ml of cue lure as an attractant and 0.1 ml of malathion was used as a toxicant except control. Treatments were installed when the flowering was started. Data collection and treatment replacement were done simultaneously in every 6-day interval. The findings revealed that the diverse fruit fly species (up to 7) were trapped in all treatments however, the Zeugodacus cucurbitae (Coquillett, 1889) followed by Zeugodacus tau (Walker, 1849) were dominating over the other species in all treatments. Yellow sticky trapped the highest number of fruit flies (15.01±0.38), followed by brewery wastage (13.65±0.37). The male-female ratio of the trapped fly was (>1) in all treatments. Furthermore, the lowest fruit fly damaged percentage (0.87±0.16) with the highest obtainable yield (32.57±1.31) and benefit-cost ratio (1.63±0.06) was observed in the yellow sticky trap. From this experiment, the yellow sticky trap captured more fruit flies caused the least amount of fruit fly damage, and yielded the highest possible yield than the other treatments.
