Artichoke (Cynara scolymus L.) is a worldwide popular horticultural crop. Interest in assessing bioactive compounds with potential health benefits in artichoke is increasing. Therefore, in this study, the variability in total phenolic and flavonoid contents of six artichoke cultivars, including five purple namely Brindisie, Opal, Conserto, Romanesco and Rouge de France as well as an ordinary white artichoke variety were investigated. The results showed significant differences in total phenolic and flavonoid contents between artichoke cultivars. Total phenolic content ranged from 17.31 mg GAE/ g DW in the white artichoke variety to 21.31 mg GAE/g DW in Romanesco. Flavonoid content ranged from 4.51 mg RE/g DW in white artichoke to 7.06 mg RE/g DW in Rouge de France. Therefore, the highest total phenolic content was shown by Romanesco. However, the highest flavonoid content was recorded for both Opal and Rouge de France. This study demonstrates the importance of genotypic variability in shaping the levels of total phenolic and flavonoid, emphasizing the need to evaluate artichoke biodiversity in order to improve its nutritional value and to contribute towards increasing the intake of antioxidants.

In this study, the antioxidant and antimicrobial potentials of the ethanol extract of the aerial parts of Lepidium spinosum Ard., which is distributed in many regions of the world, were determined. The aerial parts of the plant were dried, powdered and extracted with ethanol. Total antioxidant status (TAS), total oxidant status (TOS) and oxidative stress index (OSI) of the plant extract were determined using Rel Assay Diagnostics kits. Antimicrobial activities of the plant extract were determined against standard bacterial and fungal strains by agar dilution method. As a result of the studies, the TAS value of the plant extract was determined as 4.550±0.132, the TOS value as 12.610±0.221, and the OSI value as 0.277±0.007. In addition, it has been found to be effective at 25-200 µg/mL against standard bacterial strains and 100-200 µg/mL concentrations against fungal strains. As a result, it was determined that L. spinosum used in our study could be a natural antioxidant and antimicrobial source. In this context, it is thought that natural material may be used in pharmacological designs.

Poultry meat quality is controlled by muscle fiber properties associated with body weight gain in the immediate pre- or post-hatch period. This study aimed to determine the effect of administration of branched-chain amino acids blend (BCAAb, 3 L-leucine:1 L-isoleucine:2 L-valine) in the pre- or post-hatch period on the growth performance and fiber characteristics of the Pectoralis major (PM) muscle in turkey poults subjected to early or delayed feeding. Newly hatched poults from eggs injected in ovo with BCAAb or received no injection were used in a 21-d study. Poults (n=192) produced without injection of BCAAb received a starter diet supplemented (BCAA) or not (C) with the BCAAb (2 g/kg) immediately or with a delay of 48 h (48BCAA and 48C) after hatching. Poults (n=36) produced with (IOBCAA) in ovo injection of BCAAb (2 mg /ml) received the diet and water immediately. The BCAA and IOBCAA poults had higher body weight than those of the C, 48C, and 48BCAA birds. The body weight of the C poults was higher than those of the 48C and 48BCAA birds. The BCAA poults had higher PM muscle weight than those of the C and 48C poults, while that of the IOBCAA poults was higher than that of the 48C poults. The IOBCAA treatment increased the protein content of the PM muscle meat, compared with the C and 48C treatments. The 48C treatment increased the type IIB fiber area and the type I and type IIA fiber percentages but decreased the type IIB fiber, compared with other treatments. The numbers of type IIB and total fibers in the IOBCAA poults were higher than those of the 48C birds. In conclusion, administering BCAAb in ovo or in a starter diet enhanced early growth performance and improved the fiber characteristics of the PM muscle in turkey poults.

Yogurt is a natural source of gut-friendly bacteria. It has a considerable body of evidence that supports the significant positive effects of yogurt as probiotics on quail production performance and health. Yogurt containing bacteria can improve quail economic indexes and resistance to pathogens. With this objective, 240 growing Japanese quails were randomly distributed into three groups A1 (control), A2 (Yogurt), and A3 (Protexin) (4 replicates/treatment of 20 birds) to investigate the effect of yogurt as a probiotic source. Birds were allowed to be fed ad libitum with a commercial quail ration. Yogurt and Protexin were mixed at the rate of 5 ml/L (5ml into 1 lt. water) and 1g/L (1gm into 1 lt. water) in A2 and A3, respectively. Six (6) weeks of investigation showed a significantly higher result in yogurt than in the other two groups. Body weight had a significant difference between the control and protexin groups. Body weight gain (g) was significantly heavier in A2 at the finisher phase. No significant effect was observed in feed intake, but FCR (Feed Conversion Ratio) was significantly lower in A2, but no significant effect was noticed between A1 and A3. The mortality percentage was higher in the control group (2.66%) and lowest in yogurt (1.03%). Carcass characteristics were significantly heavier in A2 than A1 and A3. Non-carcass characteristics illustrated significant differences among the three groups, but a non-significant difference was observed in head weight. The gross return per bird was higher in A2 (12.05 BDT), whereas it was 6.55 BDT and 7.08 BDT for A1 and A3. With those observations, it can be concluded that yogurt successfully enhanced overall broiler performance and gross return of Japanese quail.

Drying characteristics of Lemon grass leaves using an oven dryer was studied at four different temperatures (40, 50, 60 and 70°C). The effect of the drying temperatures on moisture content of the leaves was investigated. Thirteen drying models were fitted to the drying data to establish the model that best describes the drying characteristics of Lemon grass leaves. The best model was determined by the model with the lowest value of SSE and root mean square error (RMSE), and the highest value of coefficient of determination (R2). Hii et al. model satisfied the conditions for selecting the most suitable and reliable model with R2, SSE and RMSE values of the model was 0.9964, 0.0250 and 0.0214 respectively. This model is most suitable at 40°C. The effective diffusivity (Deff) values ranged from 8.92452 × 10-12 m2/s to 16.00657 × 10-12 m2/s and increases as temperature increases. It was further observed that the amount of energy required to eliminate moisture within the leaves was in the range of 19.85 kJ/mol - 19.86949 kJ/mol. Dried lemongrass leaves can be used in food preservation as an alternative to synthetic substances that have recently become less acceptable to consumers. Consumers accept natural food products that are universally acknowledged as safe, such as lemon grass with essential oils, and they also fit the standards for green processing.

With the increase in the world population and the continuous development of technology, energy demands continue to increase. In general, the global energy needs are met by fossil sourced fuels. Depleting nature of fossil energy sources, their negative impacts on environment, increasing energy demands have led the efficient use of energy sources and the shift to local and renewable energy resources. Biogas is a renewable energy resource. Since organic wastes are used in biogas production, biogas offers a significant way of elimination of wastes and a source of energy. Animal wastes are the primary source of biogas. In this study, it is aimed to determine the biogas potential of Tokat province from animal wastes. Depending on this purpose, the amount of waste and biogas that can be obtained from animal waste and the energy potential that can be produced have been revealed by using the current data of the Provincial Directorate of Agriculture and Forestry. Energy equivalents of the biogas that can be obtained were also calculated. According to 2021 data, there are 303.952 cattle, 511.457 sheep and 247.333 poultry in Tokat province. Annually, 245.988 tons solid animal waste are obtained in Tokat province. In this study, conducted with the 2021 data of Tokat province, the amount of biogas that can be produced from animal wastes was calculated as 49 million m3/year. Districts with the greatest biogas potential are Merkez, Turhal and Zile respectively in 2021. The energy equivalent of biogas produced has been calculated as 292.000 MWh/year

The livestock sector plays an important role in climate change by contributing to anthropogenic greenhouse gas emissions. Studies to reduce greenhouse gas emissions in production systems of ruminant animals are of particular interest all over the world. Methane gas is formed as a result of microbial fermentation of hydrolyzed carbohydrates such as cellulose, hemicellulose, pectin and starch in the rumen. Ruminants contribute approximately 16% of global greenhouse gas emissions and 33% of global anthropogenic methane emissions. Considering its radioactive effect and global warming potential, it is estimated that the life of methane in the atmosphere, which is an important factor, will reach its half point in 12.4 years. With the increase in the world's population, the demand for animal products for nutritional purposes will need more animals and therefore total methane emissions will increase. Reducing methane emissions without reducing animal production is of critical value. In this review, methane release from ruminant animals, its reduction ways and measurement methods were examined.

In this study, olive oil producing, processing and intermediary enterprises in the TR22 Region in the 2017-18 production year were examined. As a result of the study, it was found that oil mills, olive oil factories, traders, retailers, TARİŞ and final consumers form the marketing channels in olive oil and olive oil in the research region. It was found that the waiting of oil grain olives as a result of agglomeration in post-harvest processing centers, the use of sacks in the transportation of oil grain olives, the mixing of bottom olives with the ones plucked from the branch and the use of poles in harvesting were found to reduce the efficiency. It has been found that increasing the olive paste temperature above the optimum level, opening the lid of the malaxer machine during kneading, and the emergence of the black water problem as a result of the use of three-phase and classical systems are the factors that reduce the marketing efficiency in the processing service. It was found that the marketing margin of the intermediaries was 1.64% in olive oil, 20.00% of traders in olive oil, 14.06% of factories and 22.58% of retailers. The difference between producer prices and retail prices was 51.16% for olive oil.

Family health centers in Turkey started to be implemented for the first time in Düzce in 2004 years within the scope of Law No. 5258. While determining the physical conditions of the places where family health centers are built, the first item in the regulation is that the building should be easily accessible. This situation shows the importance of the subject in terms of accessibility. While determining the features of the places where FHCs will be made, environmental characteristics are also taken into consideration. Environmental features are effective in determining the FHCs location in different ways. These impacts are divided into two groups: the physical features that pavements, roads and parks can include, and the social, cultural and institutional features of neighborhoods that include local social ties and collective activities. From this point of view, the importance of the location of family health centers relative to roads and houses is understood. The aim of this study is to examine the accessibility of Family Health Centers in Konyaaltı, Antalya, on a neighborhood basis using Geographic Information Systems. Konyaaltı has 21 Family Health Centers. As a result of the analyses, it was determined that most of the neighborhoods had problems in terms of accessibility, while a very few of them did not experience problems in terms of accessibility. In terms of the total number of buildings, the ratio of buildings that are 500 meters walking distance from any family health center by using highways is 35.56%. With these rates, 3,634 of the 10,2018 buildings remain within the limits of the regulation. Finally; suggestions were made to increase accessibility to these areas.

Domates bakteriyel benek hastalığına neden olan Pseudomonas syringae pv. tomato, yüksek yaprak nemi, ılıman sıcaklıklar ve bakterilerin konukçu bitkiler arasında yayılmasına neden olan kültürel uygulamalarla ciddi epidemilere neden olabilmektedir. Bor, tarımsal üretimde bitki gelişimi ve sağlığı için gerekli bir mikro besin elementidir. Bu çalışmada, 5 farklı dozda (1, 5, 10, 20 ve 40 mM) 14 farklı Bor bileşiğinin in vitro koşullarda 108 hücre ml-1 yoğunluktaki P. s. pv. tomato’ya karşı etkinliği değerlendirilmiş ve en başarılı bulunan 4 farklı Bor bileşiğinin (amonyum tetrafloroborat, sodyum tetrafloroborat, çinko borat ve disodyum oktaborat tetrahidrat) 5 mM dozları ile patojen enfekteli H2274 çeşidi domates tohumları kaplanarak tohumlardaki bakteriyel popülasyonlar ve tohum çıkış oranları belirlenmiştir. Denemelerde kullanılan 14 farklı Bor bileşiği arasında, domates tohumlarında P. s. pv. tomato popülasyonlarını engellemede %92 oranında disodyum oktaborat tetrahidrat en başarılı etken madde olurken, sodyum tetrafloroborat uygulamaları ile %39 oranında başarı elde edilmiştir. Araştırma sonuçlarına göre bazı Bor bileşiklerinin iyi tarım uygulamaları kapsamında, domates tohumlarında P. s. pv. tomato’yu azaltmada ekonomik, etkin ve çevre dostu bir kimyasal olabileceği düşünülmektedir.
