In this study, fatty acid composition, antioxidant activity, total phenolic compounds (TPC) and oxidative stability of cherry seed (SCO), sweet cherry seed (SCSO), mulberry seed (MSO) and plum seed oil (PSO) were determined. Oleic acid was determined as primary fatty acid (42.9-67.3%), and followed by linoleic acid (23.4-41.8%) for SCO, SCSO and PSO. Linoleic acid was determined as primary fatty acid in MSO. γ-tocopherol was determined the main and highest tocopherol isomers varied from 579.9 to 605 mg/kg oil in SCO, SCSO and PSO, whereas δ-tocopherol was determined main tocopherol isomer with 1354mg/kg oil value in MSO. Plum seed oil (PSO) was the highest antioxidant activity values in both 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azino-bis-(3-ethylbenzthiazoline-6-sulfonic acid) (ABTS) assays. There was no significant differences in lipid hydroperoxide and TBARS (2-thiobarbituric acid-reactive substance) formation among SCO, SCSO and MSO. PSO had the highest induction period (15.1 h), followed by MSO (1.4 h), SCSO (1.5 h), SCO(1.3 h). PSO was oxidatively more stable than the other oil samples. This research shows that these waste seed oils have high antioxidant capacity and tocopherol content, so they could be used in food industry.

Phosphates are widely used as food additives in meat products to increase the water-holding capacity, reduce the cooking loss and improve the textural properties. Furthermore, phosphates protect aroma and accelerate the formation of cured meat color as well as having antioxidant and antimicrobial effects. Many research about using phosphates in meat products showed that increasing chain length of phosphates improves antioxidant and antimicrobial effects. It has been stated that vacuum or modified atmosphere packaging, the use of phosphates with natural antioxidants and encapsulation of phosphates are useful approaches to enhance the antioxidant effects of phosphates. It has been reported that irradiation, vacuum or modified atmosphere packaging, storage at low temperature and the use of the salt provide strong synergistic effect on the antimicrobial properties of phosphates. In this review, researches about antioxidant and antimicrobial properties of phosphates and suggestions for the meat industry about industrial applications of phosphates are presented.

Ecological processes that occur in a lake depend on the physico-chemical (abiotic) and biotic factors of the system and the interrelations between them. It can be concluded that the current nutrient loadings from both point and non-point sources are cause to increase eutrophic case over the years. This study indicate that the sustainable utilization of reservoir in combination with proper wastewater treatment plant and controlled use of pesticides has a potential to reduce the current nutrient loadings into Suat Uğurlu Lake. The estimated nutrient reductions that could be achieved from the management scenario would be enough to revert the lake from mesotrophic situation to trophic state. The reduction of nutrient loadings into Suat Uğurlu Lake could be achieved through the practice of Integrated Water Resource Management (IWRM), through good management. However, as long as pertinent issues of urban poverty, watershed management and public awareness and involvement in water related issues are not addressed, trophic in Suat Uğurlu Lake will remain a problem.

Temel mikro-besin elementi demir (Fe) bitkide önemli rolleri bulunan birçok metalloproteinin aktif bölgesinde kofaktör olarak yer alır. Öte yandan aşırı reaktif olduğundan, hücre içerisinde fazla birikimi reaktif oksijen türlerinin üretimini tetikleyerek hücre ölümlerine neden olur. Dolayısıyla hücre içerisindeki demir homeostazı bitki gelişimi için çok önemlidir. Bitkiler demiri kök içerisine aldıktan sonra hücre içi kompartmanlara dağıtımını yaparlar. Hücre içi demir taşınımı ve dolayısıyla hücresel demir homeostazı farklı membran protein ailelerinin senkronize kontrolü sayesinde yürütülmektedir. Bu membran proteinlerinin demir eksikliği altında ifade seviyelerinin arttığı keşfedilmiştir. Bu taşıyıcıların görev ve regülasyonlarının irdelenmesi bitkilerdeki demir alım ve dağıtım mekanizmalarının anlaşılması açısından çok önemlidir. Bu yüzden bu derlemede hücre içerisine alınan demirin organellere dağıtımından sorumlu taşıyıcılar ile bu taşıyıcılar hakkındaki güncel gelişmelerden bahsedilmektedir.

This study was conducted to determine the effects of Bayvarol®, Fumidil-B®, Neo-Terramycin® on adult honeybee lifespan. Total twenty honeybee colonies were used and randomly divided into four groups (each group consisted of five colonies). Experimental groups: Bayvarol ®, Fumidil-B® and Neo-Terramycin® were treated to first, second and third groups, respectively. No treatment was done to forth group taken as control group. A hundred one day old worker bees were taken from each group and marked with different colors and numbered on the thorax. After the marked, all worker bees were given into the observation hive. Marked worker bees were controlled and counted daily. Statistical analysis of data was done by variance analysis method and between groups comparisons were done with Duncan's multiple range tests. Average lifespans of the first, second, third and control groups were 44.97±4.90, 46.86±6.56, 45.38±6.12 and 47.72±6.06 days, respectively. There were found statistically significant differences among average lifespan of first, second, third and control groups. This study showed that some drugs used to treat diseases and pests reasoned a negative effect on the lifespan of honeybees.

There are various food-processing technologies with the aim of protecting foodstuffs from environmental factors and increasing their shelf life. One of these is encapsulation technology, which has recently been used with an increased interest. With the fluidized bed coating, which is one of the physical methods used for encapsulation, the solid core materials are fluidized via the air stream and a film layer is formed on the surface of the core material with the coating material. The applicability of the fluid bed coating technique, as well as particulate properties, is significantly influenced by process variables used in the system, environmental variables and thermodynamic factors. The release characteristics of capsules formed during the process can be changed by various mechanisms such as heating, dissolution, mechanical or chemical fracture etc. and controlled release can be achieved. The fluidized bed coating method not only has the advantage of controlled release but also provides a homogeneous powder product, reduction of fine particles, development of transport and storage facilities, protection of reactive components, and prevention unwanted taste and odour. In this study, researches on fluid bed coating mechanism, fluid bed coating systems and applications of fluid bed systems in the food industry have been reviewed.

Antibiotic resistance is being constantly developed worldwide. Coagulase Negative Staphylococci (CNS) and Staphylococcus aureus are common causes of bovine subclinical mastitis. Bioactive compound of medicinal plants shows anti-microbial, anti-mutagenic and anti-oxidant effects. The anti-bacterial and anti-oxidant activities of Liquidambar orientalis (L. orientalis) extracts on subclinical mastitis causing bacteria in cows have not been reported to date. The aim of the present study was to examine anti-bacterial and anti-oxidant effects of L. orientalis leaf extracts on S. aureus and CNS isolated from cows with subclinical mastitis symptoms. In this study, 3.2 mg/mL minimum inhibitory concentration (MIC) of ethanol extracts of L. orientalis has shown to be a most potent anti-bacterial and anti-oxidant for all isolated bacterial species from mastitis cows. In this study, it was investigated anti-bacterial and anti-oxidant potentials of acetone, methanol and ethanol extracts of the L. orientalis. The acetone extract showed maximum inhibition zone against S. aureus numbered 17 (12 mm). In addition to anti-bacterial properties, anti-oxidant activity of L. orientalis extract was examined by ABTS [2,2'-azino-bis (3-ethylbenzothiazoline-6-sulphonic acid)] free radical assay. Trolox was used as a positive control anti-oxidant. Ethanol extract exhibited a strong anti-oxidant activity like Trolox anti-oxidant which was effective at 2.58 mM concentration. Bioactive compounds of sweet gum may be useful to screening mastitis causing bacteria for clinical applications.

This study aims to explore the relations between governance and agricultural performance of countries. Data Envelopment Analysis was used to find out agricultural performance of 81 countries at first stage. Panel data regression was employed in the second stage to assess the relations between performance levels of countries and their governance. Six governance indicators namely; voice and accountability, control of corruption, government effectiveness, regulatory quality, rule of law and political stability and violence were analyzed in this stage. Findings show that firstly, governance indicators are highly correlated with each other. Secondly, developed countries are more efficient and have better governance than developing and undeveloped countries. Finally, a quadratic form of regression was the fitting model that is the marginal effects of good governance on performance are increasing in high values of governance.

Field experiments were carried out during the dry seasons in (2012-2013 and 2013-2014) to study the impact of Integrated Nutrient Management on some soil properties and nutrients uptake by red onion (Allium cepa L.) in Moda, Michika, Adamawa state, Nigeria. Soil samples were randomly collected and analysed for pH, EC, organic carbon, organic matter, total nitrogen, available phosphorus before and at the completion of the experiment. Total nitrogen, phosphorus and potassium contents of the onion bulbs were determined. There was an improvement in the fertility status of the soil as a consequence of integrated nutrient management. Combined organic and inorganic fertilizer application influenced the uptake of nitrogen, phosphorus and potassium by red onion. The highest nitrogen, phosphorous and potassium uptake by onions of 0.76, 43.82 and 2.42kgha-1 occurred when all treatments were combined. Uptake of N and K increased as treatment level increased. The P uptake was highest at lower treatment levels and could be linked to sufficiency of indigenous soil P for plant growth resulting in high P uptake with minimal addition of nutrient inputs. Integrated Nutrient Management could be adopted to improve soil fertility status and N, P and K uptake by red onions.

Araştırma serbest sistem yumurta tavukçuluğunda kullanılacak uygun tavuk materyalini belirlemek üzere yürütülmüştür. Bu amaçla yerli kahverengi yumurtacı Atak-S genotipi ile YB kodu verilen yabancı kahverengi ticari yumurtacı genotip verim ve yumurta özellikleri bakımından karşılaştırılmıştır. Araştırmada her bir genotipten 150’şer adet olmak üzere toplam 300 adet tavuk kullanılmıştır. Her genotip kendi arasında üç parsele ayrılmış ve her parselde 50 tavuk barındırılmıştır. Derin altlıklı yer sistemli kümes içerisinde birim alanda (m2) 5 tavuk yetiştirilirken, otlatma alanında ise tavuk başına 4 m2 alan ayrılmıştır. Aynı gün kuluçka çıkışı yapılmış olan yarkalar 16 haftalık yaşta özel bir firmadan temin edilmiştir. Araştırma 80 haftalık yaşa kadar sürdürülmüş olup bu süre zarfında verim ve yumurta kalite özellikleri tespit edilmiştir. Bu özelliklerden, %50 yumurta verim yaşı, yumurta ağırlığı, tavuk-gün yumurta verimi, tavuk-kümes yumurta verimi, yaşama gücü, ak indeksi, sarı indeksi, haugh birimi ve sarı rengi bakımından genotipler arasında farklılık bulunmamıştır. Buna karşın, 18-80. hafta canlı ağırlığı, yem tüketimi, yemden yararlanma oranı, şekil indeksi, kabuk kalınlığı, kabuk direnci, et-kan lekesi oranı ve kabuk rengi bakımından ise genotipler arasındaki farklılığın önemli olduğu tespit edilmiştir. Araştırmada, genotiplerden herhangi birisinin bütün özellikler bakımından öne çıkmadığı belirlenmiştir. Ancak, piyasa şartları dikkate alınarak yapılan ekonomik analiz sonuçları ve hayvan hassasiyetleri bakımından yapılan gözlemler neticesinde Atak-S genotipinin serbest sistem yumurta tavukçuluğuna daha uygun olduğu sonucuna varılmıştır.
