This study aims to determine various relationships between liver, gonad and body weights of the two pipefish species caught in two breeding seasons from the Bafa Lake (Muğla) coasts between 2014 -2016. Using beach seine-net in the lake, a total of 208 pipefish specimens (79 Synathus abaster and 129 Synathus acus) were sampled. L-W relationship and Fulton condition factor were W = 2E - 0.94.01, 0.035 ± 0.009 in S.abaster specimens. Also LW relationships and condition factor were W = 8E-0.93.83 , 0.033 ± 0.01 in S. acus. On the other hand mean ± SD of HSI and GSI values were 2.18 ± 1.65 and 7.69 ± 7.12 respectively. In S.acus values 3.22 ± 3.13 and 5.49 ± 5.12 as well. The decrease in HIS and K values, provides sufficient information to claim that species in the lake spend all energy requirement obtained with proper feeding to growth and gonad development.

This research was performed to elucidate the effects of temperature on the degradation kinetics of anthocyanins in shalgam beverage. Shalgam beverage was produced according to traditional production method. Then, it was kept at three different temperatures (65°C, 75°C, and 85°C) for 12 hours, and the relevant quantities of anthocyanins were determined thereafter. The research revealed that degradation of the anthocyanins was well described with a 1st-order reaction kinetics model and the R2 values varied in the range of 0.9059-0.9715. Activation energy of the reaction was determined to be 48537 Joule/mole. The half-lives of anthocyanins at 65°C and 75° C, and 85°C were found to be 138.63, 136.72, and 51.57, respectively. Compared the half-life periods at different temperatures, anthocyanins were found to be more resistant at 65°C and 75°C than at 85°C.

Peynir üretimi ile eski zamanlardan bu yana önemli bir yere sahip olan Kırklareli ilinde önemli ticari potansiyele sahip olan iki farklı peynir, Kırklareli Beyaz Peyniri (KBP) ve KBP ve KEKP üretiminde belli oranlarda koyun sütü, keçi sütü ve inek sütü karışımı kullanılmaktadır. Kırklareli peynirlerini ayırt edici kılan temel bazı özellikler mevcuttur. Bu özellikleri coğrafi yapı ve iklim koşullarına bağlı olarak ortaya çıkan doğal bitki örtüsünün getirdiği etki, peynir hammaddesi olan sütün taşımış olduğu farklılıklar, son olarak ve en önemlisi ise üretim yöntemi ve olgunlaşma sürecinde yer alan temel farklılıklar ile belirtildiği gibi süregelen tarihsel ustalık şeklinde özetlemek mümkündür. KBP ve KEKP taşıdığı farklılıkları bir zincir gibi hayvan beslenmesinden, süte, sütten peynire yansımaktadır. İlin botanik kompozisyonunu oluşturan türlerin oranları hayvanların yemini oluşturmaktadır. Botanik özelliklerine göre Kırklareli meralarında yaygın olan bitkiler buğdaygiller (Poaceae), baklagiller (Fabaceae), geniş yapraklı otlar (Asteraceae, Apiaceae, Lamiaceae vd.) ve çalılardır (Fagaceae vd.). Bu 3 farklı bitki grubunun süt ve peynir üzerine farklı şekillerde etkileri bulunmaktadır ve protein miktarı, yağ oranı vb. gibi en temel kalite kriterlerini etkilemektedir. Bunların dışında sütün mikrobiyal yükünün çok düşük olması ile başlayan ve üretim koşullarının getirdiği birçok farklılık ta mevcuttur. İlde üretilen sütlerin AB kriterlerine uygun olması, öncelikle düşük pastörizasyon sıcaklığı gibi çok önemli bir avantajı beraberinde getirmektedir. Üretimlerinde yalnızca inek sütü kullanılabileceği gibi koyun sütü, keçi sütü ve inek sütü karışımı da kullanılabilir. Karışım oranları ise %30-%45 koyun sütü, %25-%40 keçi sütü, %15-%30 inek sütü şeklindedir.

Pesticides have both acute and chronic effects on humans and all other warm blooded living things. In pesticide applications, few of the amount used reaches the target organisms, whereas the rest mixes into the ecosystem and leads to the deterioration of the ongoing natural balance. Therefore, growing attention has been given toward the development of alternate environmentally friendly pesticides/insecticides that would aid an efficient pest management system and also prevent chronic exposures leading to diseases. In this context, plant-derived natural products are considered valuable candidates to reverse this negative trend. Botanical pesticides are relatively safe, degradable, and are readily available sources of biopesticides. Neem is an ideal alternative candidate as a natural non-synthetic plant pesticide. The neem products have been obtained from several species of neem trees in the family Meliaceae. Array of more than 300 bioactive compounds in the neem tree makes it a unique plant with potential applications in pest and vector management. Botanical pesticides, such as neem, have limited persistence in the environment, and ultraviolet light, temperature, rainfall and other environmental factors can degrade neem. Unlike toxic synthetic insecticides, neem materials do not kill the pest, but incapacitate or neutralize it via cumulative behavioural, physiological, and cytological effects. In spite of high selectivity, neem materials affect more than 400 harmful species including insect pests, phytophagous mites, mites, and ticks affecting man and animals, parasitic protozoans, noxious molluscs, plant parasitic nematodes, pathogenic fungi, and harmful bacteria and fungi. Neem ingredients affect insects in various ways such as repellent, antifeedant, toxic, fecundity and growth regulatory effects. This review presents an overview of recent advances in research on the environmental impact of neem products and their use and effectiveness as a biopesticide.

Due to rapidly increasing population and urbanization, agricultural lands are shrinking. However, environmental problems and pollution are constantly increasing. This poses a threat to agricultural production and food access. In order to overcome these threats, the use of fully controlled indoor production systems called plant factory is becoming widespread. The management of plant nutrition and monitor of environmental conditions is very important for production in the plant factory. Plant production is sensitive to environmental conditions. For this reason, it is necessary to make accurate measurements in order to ensure the correct climatic conditions. The high cost of control systems designed for this purpose is a problem for producers. In this study, a mini plant factory prototype and control system are presented which is developed by using open source hardware and software. In addition, the temperature, relative humidity and light measured by the low-cost sensors were compared with the reference devices and the system performance and stability were investigated.

Two different thyme species (Thymus vulgaris L. and Origanum majorana L.), sage (Salvia officinalis L.) and lavender (Lavandula officinalis L.) extracts were tested against pre-adult stage of Potato tuber moth-PTM [(Phthorimaea operculella (Zeller) (Lepidoptera: Gelechiidae)], which is an important quarantine pest. Each plant extracts prepared with ethanol were applied to larvae and eggs in three different concentrations 3%, 5 and 10 ml/L. In the egg treatments at the highest concentration (10% ml/L), inhibition rate was observed in Lavander and T. vulgaris 73.7%, in O. majorana 67.5% and in sage 66.2%, respectively. Results indicated that the mean number of hatching eggs were highly decreased as concentration increased, the highest decreased was observed with treated 10% concentration. of lavender and T. vulgaris. Observation were for 7 days. In the insecticidal toxicity study of against the larval stage, mortality were determined at the highest concentration (10% ml/L) in O. majorana 91.2%, Lavander 90%, T. vulgaris 87%, and Sage 83.7% at the end of 7th day. It was also determined that the larval mortality rate was higher with the increasing of extracts of 4 different plant depending on time. As a result, in this study, ovicidal toxicity of plant extracts was recorded against to on egg stage and it was that impact of insecticidal against to on larval stage also.

This study was carried out to determine the concentrations of some heavy metals (Cd, Cu, Pb, Zn, Cr and Fe) in Solen marginatus (Pulteney, 1799) and sediments in the middle region of Izmir Bay. Metal concentrations in S. marginatus vary in the one-year period between summer 2005 and summer 2006. The order of accumulation of metal concentrates in soft tissue of razor clam was determined as Cd < Pb < Cr< Cu < Zn < Fe. Metal accumulations in the soft tissue of S. marginatus were compared with Provisional Tolerable Weakly Intakes (PTWI) and Provisional Tolerable Daily Intakes (PTDI) for human consumption. The results show that the maximum concentrations of metals were markedly below the limits of the FAO (Food and Agriculture Organization), WHO (World Health Organization) and TFC (Turkish Food Codex) for human consumption. The order of the metal concentrations detected in the sediment samples was Cd < Pb < Cu< Cr < Zn < Fe. In this study, the maximum heavy metal values determined in the sediment are below the criteria values of the stated for international sediment quality guidelines in the NOAA (The National Oceanic and Atmospheric Administration), OMEE (The Ministry of Environment and Energy of Ontario), ANZECC (The Australia and New Zealand Environmental on Conservation Council), CCME (The Canadian Council of Ministers of Environment). There was a statistically significant but weak correlation between concentrations of Cu and Cr in sediment and S. marginatus. The significant correlations have shown that Solen species can be used as a bioindicator species, such as mussels due to their ability to accumulate heavy metals.

Gaziantep pita, one of the regional flat breads in Turkey, had the geographical sign registration certificate in 2017. Gaziantep pita quality is directly related to flour properties. In present study, physico-chemical and flourgraph properties of bread flour containing 0.550% and 0.650% ash content (d.b.) were investigated. Results showed that the moisture contents of both samples were not significantly different from each other and were under upper limit of 14.5%. Sedimentation values for 0.550% and 0.650% ash content (db.) of flours were found good, between 25-36 mL. Wet gluten contents of both flours were determined as medium, between 20-27%. The falling number values for the samples were higher than normal values. The extensibility values were in normal values for both flour samples. The resistance to extension values for both samples were low, although these values were significantly different from each other. Energy value of 0.550% ash content (d.b.) of bread flour was in normal value, while energy value of 0.650% ash content (d.b.) of flour was low. Physico-chemical and flourgraph properties of 0.550% and 0.650% ash content (d.b.) of flours could be improved by blending or adding α-amylase.
