Doğum sonrası sütten kesime kadarki süreçte buzağılara probiyotik kullanımının buzağıların gelişme ve sağlık durumları üzerine olan etkilerinin belirlenmesi amacıyla yürütülen bu araştırmada 24 baş (20 baş dişi ve 4 baş erkek) Holstein ırkı buzağı doğum tarihi, cinsiyet ve doğum ağırlıkları dikkate alınarak kontrol grubu (KON, n=12) ve probiyotik grubu (PRO, n=12) olmak üzere ikiye ayrılmıştır. Çalışmada farklı mikroorganizma suşlarını (Enterecoccus spp, Lactobacillus spp. Pediococcus spp., ve Bacillus spp.) içeren ticari bir probiyotik kaynağı kullanılmış olup probiyotik grubundaki buzağılara süt ikame yemi (SİY) ile birlikte sabah öğününde 20 ml/gün baş düzeyinde verilmiştir. Buzağılar doğumu takiben bireysel kulübelere alınmış ve ilk 3 gün boyunca günde 4 L/gün ağız sütü, tükettikten sonra 4-17. günlerde 6L/gün, 18-45. günlerde 9L/gün, 46-55. günlerde 6L/gün ve 55. günden sütten kesime kadar 3L/gün SİY tüketmişlerdir (150 g toz/1L). Buzağılara 4. günden itibaren sütten kesime kadar serbest düzeyde buzağı başlangıç yemi ve su verilmiştir. PRO buzağılara 4. günden sütten kesime kadar ki süreçte sabah öğününde verilen SİY içerisine 20 ml probiyotik ilave edilmiştir. Çalışmada yem tüketimi, ishal ve sağlık ile ilgili veriler günlük olarak takip edilmiş, canlı ağırlık verileri ise doğum, 4., 18., 46., 55. günlerde ve sütten kesimde ölçülerek kayıt edilmiştir. Çalışmada, KON ve PRO grubu buzağılarda ölçülen SİY ve başlangıç yemi tüketimleri ile günlük canlı ağırlık artışları (GCAA) ve sütten kesim sürelerinin benzer olduğu (P>0,05), buna karşın, PRO grubunda ishal görülme sıklığını %50 oranında, pnömoni görülme sıklığının ise %54 oranında azaldığı belirlenmiştir (P≤0,05). Sonuç olarak yenidoğan buzağılarda probiyotik tüketiminin performans üzerine herhangi bir etkisi olmazken sağlık üzerine olumlu etkilerinin olduğu belirlenmiştir.

Triano Cornejo, Ana | Perez Gonzalez, Eugenia | Fernández Del Castillo, Tomás | Ruiz Sinoga, José
The western Mediterranean is an area particularly affected by the effects of climate change, which makes it a hotspot, and it is also an area where there is particular competition for land use, where subtropical crops coexist with traditional crops including vines, olives, and almond trees, and where there is growing demand for urban development and tourism. It is one of the most sensitive to the effects of climate change because of the markedly contrasting extreme events, including heat waves, torrential rains and drought. In this study we analysed changes in land use, torrential events and the effect of rainfall on vegetation cover and soils in two basins, the main objective being to analyse the evolution of land use and water erosion in recent decades. The two basins are similar but have different configurations and contrasting uses. One has steep slopes and is characterized by more typical Mediterranean crops, such as vineyards, while the other has been subject to clearing that has modified the steep slopes, and where there has been a change to more competitive crops, including subtropical crops. The results highlight the continuous increase of irrigated crops and urban areas and a gradual disappearance of rainfed crops, the occurrence between torrential events and the correlation between monthly rainfalls and vegetation cover.

This study investigated the effects of various guar gum edible coating formulations, incorporating different proportions of waste leek powder and sunflower oil, on weight loss, color parameters (L*, a*, b* values, and ΔE), texture, and shrinkage of Agaricus bisporus mushrooms during a 7-day storage period. The goal was to assess the potential impact of these coatings on preserving the mushrooms’ quality over time. The results showed that the coatings had a significant effect on reducing weight loss compared to uncoated samples. The lowest weight loss was observed in the 0.5% leek powder and without sunflower oil, while the highest was in 2.5% leek powder and 0.1% sunflower oil. Shrinkage was also positively affected by the coatings, with 1.5% leek powder and without sunflower oil showing the most promising results. The L* values of the coated samples declined slightly, indicating better color preservation, while the a* values exhibited stable redness/greenness. On the other hand, b* values increased, indicating an increase in yellowness during storage. The ΔE values were lower for the coated samples, suggesting less color deviation compared to uncoated ones. Overall, the study indicates that these edible coatings have the potential to maintain the quality of mushrooms during storage, leading to better preservation and extended shelf life.

ABSTRACT. The paper presents a series of results regarding the application of GNSS technology for measuring displacements to earth dams. An appropriate horizontal and vertical deformation-tracking network must be established for the rapid monitoring of earthmoving movements. Data obtained from the monitoring network can be used in the earth dam stability analysis program. Periodic tracking of earth dams using GNSS technology provides high accuracy of spatial distortions. The results of the paper show the application of GNSS technology to monitor the deformations of the Podisu earth dam located on the Sheep Valley River in Iasi County. In the first stage of research (2019 and 2020), the local geodetic tracking network was created. To monitor the dam, four control landmarks were placed on the crest of dam and seven landmarks on the downstream slope. In the second stage of the research (year 2021) the measurements of the displacements at the earth dam were performed. The GNSS monitoring method has the advantage of positioning the target quickly, statically, and with high accuracy. The measurements used fixed stations located at two points in the local geodetic network. Four Trimble GNSS receivers were used for the measurements. The resulting data was processed using the Trimble Business Centre program. The obtained results were analysed in comparison with those existing in the design documentation and technical expertise of the dam. The results highlight the presence of displacements on the crest of a dam and slopes of the dam. The final findings highlight the performance of GNSS technology in the monitoring process, where it provides millimetre-accurate accuracy with high spatial and temporal accuracy.

This study was carried out in Isparta University of Applied Sciences, Faculty of Agriculture, Agricultural Research, and Application Farm in 2021 to determine the effect of different irrigation water levels on tuber yield and quality parameters of the Agria potato variety. Drip irrigation method was used in the study and five different irrigation water levels (S1: 120% of the seven-day ETo, S2: 90% of the seven-day ETo, S3: 60% of the seven-day ETo, S4: 30% of the seven-day ETo, S5: No irrigation except germination and emergence) were determined based on the reference evapotranspiration (ETo). Irrigation water (IW) amounts varied between 85.66-639.26 mm and evapotranspiration varied between 296.54-825.15 mm. Different amounts of IW significantly affected the vegetative growth, yield and quality parameters of potato. As irrigation water decreased, total tuber yield and marketable yield declined. Total tuber yield and marketable yield were 46.11 t/ha and 40.59 t/ha, respectively, in S1 treatment where the maximum amount of IW was applied, while they were 12.96 t/ha and 6.37 t/ha, respectively, in S5 treatment where no irrigation was applied. Logarithmic relationships were determined between evapotranspiration and total yield and between the amount of IW and total yield. Water use efficiency was determined between 43.69-55.88 kg/(ha×mm) and irrigation water use efficiency between 32.34-51.86 kg/(ha×mm) and yield response factor (ky) was calculated as 1.19.

The fly ash generated from a Romanian power plant was used as a starting material in this study. The aim of the study was to obtain a low cost material based on the treatment of fly ash with Fe3O4 for utilization as an adsorbent for cadmium ion removal. The adsorbent that was synthesized was characterized using different techniques. The adsorption process was investigated by the batch technique at room temperature. The quantity of cadmium ion adsorbed was measured spectrophotometrically. The experimental data showed that the material can remove cadmium ions at all three working concentrations. The adsorption capacity increased with an increase in concentration, respectively contact time. The results were analyzed through two kinetic models: pseudo first order and pseudo second order. The kinetics results of cadmium adsorption onto a magnetic material are in good agreement with a pseudo second order model, with a maximum adsorption capacity of 4.03 mg/g, 6.73 mg/g, and 9.65 mg/g. Additionally, the pseudo second order model was linearized into its four types. The results indicated that the material obtained show the ability to remove cadmium ions from an aqueous solution.

This study aims to define the concept of office spaces and their requirements, as well as the contemporary interior design approaches. It will also cover the interior design and application process for an architecture office in Konya. The company, originally named Çınar Architecture and active in Konya between 1985 and 1990, has been operating as Kerimler Planning Construction Consultancy Company in Konya since 1995. The company requested an interior architecture project for their new location. In the current environment, the office is starting to become outdated and is unable to offer users enough physical amenities. The main goal of the new office’s interior design was to create areas where employers and employees could collaborate in a welcoming and adaptable setting without facing any kind of discrimination. In Konya Meram Pirebi District, the Menekşe Apartment’s ground floor, which is currently a street-level store, is the site of the project, which occupies a total of 280 m2 and consists of a ground + basement. The office occupies 145 square meters on the ground floor of a recently constructed building, with glass extending to the open floor on the south, north, and west facades. The room has a very large opening because the columns are concealed by the walls, making the two stories easily visible from the entrance. The office, which occupies a 135 m2 basement floor, is connected to the elevator and staircase at the back. Natural light enters the basement through the gallery area that is attached to the staircase. Within the parameters of the study, two- and three-dimensional architectural design tools, including phases of the interior design process, were employed in conjunction with a qualitative research method based on inspection and observation. The architectural office put it into practice about half a year after the design stage. The outcome was the creation of a dynamic, modern office analysis that values teamwork and permits the emergence of unique and creative ideas throughout the project.

In Ethiopia livestock feed shortage and soil acidity are serious problems. In recent years sweet lupins (white and blue species) were introduced as multipurpose crops in the country. However, there is no information about their nodulation potential. This study was conducted to evaluate nodulation potential of these sweet lupins and their effect on nitrogen (N) and phosphorous (P) content of the soil. Seven lupin varieties were evaluated using factorial arrangement (seven varieties * two inoculations) in a randomized complete block design in two locations for two years. The result showed that effect of inoculation and location was not significant (P > 0.05) on biomass, seed, nodule number and soil parameters. While the effect of variety was significant (P < 0.05) on nodule parameters. Its effect on dry biomass and seed yields was also significant in either of the years. Variety and year had no effect on soil N and P contents. In the first year, blue sweet lupin entries had the highest nodule number per plant, 222 nodules. In the second year similar nodulation performance was observed among species and varieties. Soil N and P were not affected by varieties and inoculation. In addition to their yield advantage, compared to the sweet white entries, blue sweet lupin varieties had high potential in nodulation. Therefore, these introduced sweet blue lupins can be used as multipurpose crops in acidic soils of Ethiopia.

Due to the increase in food-borne diseases, especially in recent years, consumers' orientation to healthy products and their emphasis on consumption force producers to environmentally friendly products. Nitrogen is the most widely used plant nutrient in the world. Nitrogen, a very expensive input due to its excessive use, pollutes the environment and causes nitrate accumulation in plants. Therefore, vegetable growers strive to replace chemical fertilizers such as nitrogen with environmentally friendly and cost-effective sources. PGPRs stand out in this regard and at the same time, their potential in environmentally and consumer-friendly vegetable production needs to be revealed. In this study, the importance and potential role of N2-fixing PGPR are discussed for the improvement of yield and yield components in environment-friendly vegetable production for healthy human nutrition.

Black soldier fly larvae (BSFL; Hermetia illucens L.) is a proven high-cost protein source replacer and could be grown in a range of bio-degradable waste materials where hardly incorporated into broiler diets locally. The present study was aimed to assess the nutritional composition of BSFL, and apparent metabolizable energy (AME) value of BSFL meal provided to broiler chickens. BSFL full-fat meal produced from kitchen waste as a substrate were examined for their proximate composition, minerals and fatty acid profile. Eighty, 21-d old unsexed Cobb-500 broiler chickens (BW±SD: 665.8 ±14.3 g) were assigned randomly into 16 battery cages (04 replicates, five birds/replicate). A maize-soybean meal-based diet was used as the basal diet which was partially substituted by pre-analyzed BSFL meal at the rates of 5%, 10%, and 15% to produce three test diets. Birds were fed in a completely randomized design for 7-d with a 4-d adaptation period. Excreta were collected for three days from day 25 to 28. The results envisaged that the crude protein (CP) and ether extract (EE) contents of the kitchen waste were 12.3%, and 10.5%, respectively. BSFL meal when analyzed had 34.4% CP and 47.3%, EE. The fatty acid (FA) profile of the kitchen waste was more or less similar to that of BSFL‘s meal. The estimated AME of the BSFL full-fat meal fed for broilers was estimated to be 15.7 MJ/kg. The BSFL full-fat meal can be utilized sustainably in feed formulation and has a high potential to replace costlier feed ingredients.

Türkiye; birbirinden farklı ekolojik özelliklere sahip olup akarsu ve göller bakımından zengin bir ülkedir. Bazı akarsularımız da yer altına sızarak veya sıcaklığın etkisiyle buharlaşarak kaybolur. En büyük gölümüz Doğu Anadolu'da yer alan sodalı Van Gölüdür. 2021 yılında Türkiye’de su ürünleri üretim miktarı yaklaşık 800 bin ton olup bu miktarın %59’u yetiştiricilik yolu ile elde edilirken %41’i avcılık yolu ile elde edilmektedir. Avcılığın %10’u iç sulardan karşılanırken, yetiştiriciliğin yaklaşık %29’unu oluşturmaktadır. Yapılan bu çalışmada, Van ilinin son 22 yıllık (2000-2021) su ürünleri üretim miktarının elde edilmesi hedeflenmektedir. Bu amaçla Türkiye istatistik Kurumu (TUİK, 2000-2021) veriler yardımı altında Van ilinde yapılan avcılık ve yetiştiricilik yoluyla elde edilen türlerin trend analizi ile 2050 yılına kadar üretim miktarının tahmin edilmesi amaçlanmıştır. Van ilinin 2000-2021 yılları arasında avcılık yoluyla en çok avlanan iç su balıkları türleri sırasıyla; İnci Kefali (Chalcalburnus tarichi), Sazan (Cyprinus carpio), Siraz (Capoeta Pestai), Alabalık (Salmo spp.). Yetiştiriciliği yapılan tür ise sadece Alabalık’tır. Sonuç olarak, Van ilinde avcılık yoluyla elde edilen tatlı su balıkları üretiminde yıllara bağlı olarak genel bir azalmanın varlığı gözlenmektedir. Hatta bu şartlar devam ederse Siraz balığının 2022 yılında üretim verilerinde, Sazan balığının ise 2024 yılında üretiminin sona ericeği tahmin edilmiştir. Bunun yanında yetiştiricilik yoluyla üretilen tek tür olan Alabalık üretiminin artacağı bulunmuştur.

This study was carried out to examine the prevalence of AFM1 contamination across different areas of Chattogram, Bangladesh, and to assess the level of AFM1 in raw milk samples from various dairy farms. A cross-sectional study was conducted to assess the farming standards of three different Chattogram neighborhoods—Bakalia, Khulshi, and Pahartali—and to ascertain the amount of AFM1 in milk. In the study location, 30 commercial dairy farms were randomly chosen, and data on farming methods, milk production techniques, and knowledge of aflatoxin contamination were gathered. Using the enzyme-linked immunosorbent assay (ELISA) method, collected milk samples (n = 90) were examined for the presence of AFM1. The farms produced 71.67±14.71 liters of milk on average every day, which was primarily supplied to dairy processing plants. For feeding the cows, all farms used concentrates and forage. The mean concentration of AFM1 in milk samples collected from Bakalia was higher (190.00±120.87 ng/L) than that in milk samples collected from the Khulshi (108.44±66.19 ng/L) and Pahartali (189.25±160.78 ng/L). The overall prevalence of AFM1 was 43% (N=39) of the total examined samples. A total of 69% (N=27) and 5% (N=2) of AFM1 positive samples exceeded the European Union Regulation (50 ng/L) and BSTI/BFSA regulations (500 ng/L) respectively. There was a significant difference in the occurrence of AFM1 in Bakalia regarding Khulshi and Pahartali. This research will aid in measuring the AFM1 content in raw milk and helping to address public health issues.
