Survey of wild food plants for human consumption in Karaisalı (Adana-Turkey)
No full textThis study identified not only the wild plants collected for food purposes by local people of Karaisalı County in the Mediterranean Region, but also the uses and local names of these plants. Field study was carried out over a period of approximately 2 years (2008–2010). During this period, 76 vascular plant specimens were collected. Demographic characteristics of participants, vernacular plant names, edible parts and utilization methods of the plants were investigated and recorded. In the scope of the study, the plant species were collected; herbarium materials were prepared; and the specimens were entitled. In addition, the use-value of the species was determined and was calculated for the food plants included in the study. A total of 76 food plants belonging to 30 families were identified in the region. The most common families are: Asteraceae (12 plants), Lamiaceae (10 plants), Rosaceae (9 plants), Polygonaceae (5 plants), Apiaceae (4 plants). The study showed that the plants used are either eaten raw or ripe, cooked as vegetable dish, consumed as jam, consumed as coffee, as spice, frying in oil or baked to be served as dishes such as stew, pie made by roasting the leaves, prepared sour souce is added to food. During this ethnobotanical research, it was verified that wild edible plants play an important role in diet in Karaisalı. We examined whether the plants used had literature records or not. Varied usages of a number of plants have been recorded for the first time by us. Tree of those plant are endemic. The plant flora of Karaisalı is threatened by such factors as grazing, expansion of new agricultural lands, and unsustainable picking of plants to generate income. Steps should be taken immediately to ensure the inclusion of relevant flora within conservation designations
Kayıplı Veri Sıkıştırma için Fraktal Görüntü Sıkıştırma Yöntemi
No full textGünümüzde kayıplı görüntü sıkıştırmada en çok
kullanılan yöntemlerden bir tanesi JPEG sıkıştırma yöntemidir.
Ancak JPEG sıkıştırma yönteminin dezavantajları vardır. Bu
dezavantajları gidermek için fraktal görüntü sıkıştırma yöntemi
önerilmiştir. JPEG sıkıştırma yöntemi küçük boyutlu
görüntülerde iyi sonuçlar vermekte ancak büyük boyutlu
görüntülerde sıkıntı yaşamaktadır ve görüntünün boyutu arttıkça
hem doğruluk oranı hem sıkıştırma oranı düşmekte hem de
sıkıştırma ve kod çözme çok uzun süreler almaktadır. Ancak
fraktal sıkıştırma yöntemi bu sıkıntıları ortadan kaldırmaktadır.
Programlar matlab dilinde yazılmış olup sonuçlar
değerlendirilmiştir. Görüntülerin boyutu arttıkça fraktal
sıkıştırma yönteminin çok daha uygun olduğu gözlemlenmiştir
Effect of brine and dry salting methods on the physicochemical and microbial quality of chub (Squalius cephalus Linnaeus, 1758)
No full textThe present study, looks at the physicochemical and microbiological quality changes that occur due to different salting techniques (20% salt concentration) of chub (Squalius cephalus) and when stored in 4 ± 0.5 °C. Samples of fish from each group was taken on the 15, 30, 45, 60, 90 and 120th day and was analyzed for nutritional component (crude protein, lipid, moisture, crude ash), pH value, salt content and the microbial flora (total mesophilic aerobic bacteria count, total coliform, total psychrophilic aerobic bacteria count, yeast and mould). It was determined that crude protein, lipid, crude ash and salt amounts in the group where dry salting method was applied were higher than the group where brine salting occurred, in addition protein and lipid values decreased as storage period was longer (P < 0.05). It was determined that there is an increase in total aerobic mesophilic, psycrophile bacteria and enumeration of yeast and mould as storage period increased, while coliform bacteria decreased (P < 0.05).This work was supported by Munzur University Scientific Projects Coordination Department (Project Number: YLTUB012-03)

Effect of post-heat treatment on microstructure and mechanical properties of cu-fe-co powder alloy fabricated by hot pressing
No full textIn this study, the powder mixture which consists of Cu-Fe-Co was produced by using the method of hot pressing technique. In addition, effect of heat treatment process on microstructure and mechanical properties of this alloy was investigated. Following the hot pressing process applied on the samples, heat treatment was carried out at 950°C for two different dwelling times (90 and 180 minutes). Measured density values were considered as physical characteristics, while hardness and fracture strength values were considered as mechanical characteristics. It was observed that porosity rates of hot pressed samples were decreased by increasing of temperature and pressing parameters. In this study it was observed that Cu was spread in matrix and filled the micro porosities. Hardness values were determined to be decreased as a result of grain growth after heat treatment process. That 4 fold increased elongation % values which were achieved by TRS experiments were observed as well

Maslinic acid as an effective anticancer agent
No full textMaslinic acid (2α,3β-dihydroxyolean-12-en-28-oic acid) is a naturally occurring pentacyclic triterpenic compound. Maslinic acid is gradually gaining attention as an excellent pharmacologically active product because of its premium biological properties. In this review we will focus on chemopreventive properties of Maslinic acid against different cancers. Seemingly, available data is limited and we have yet to unravel how Maslinic acid therapeutically targeted oncogenic cell signal transduction cascades in different cancers. Moreover, there are visible knowledge gaps about the ability of Maslinic acid to modulate oncogenic and tumor suppressor microRNAs in various cancers
Biochemical responses of Gammarus pulex to malachite green solutions decolorized by Coriolus versicolor as a biosorbent under batch adsorption conditions optimized with Response Surface Methodology
No full textThe current study was aimed to investigate the detoxifying and antioxidant enzyme response of Gammarus pulex exposed to malachite green (MG) after decolorization by Coriolus versicolor. Response surface methodology (RSM) was utilized to optimize the decolorization conditions of MG synthetic solutions by C. versicolor. Glutathione (GSH), malondialdehyde (MDA) levels and glutathione peroxidase (GPX), catalase (CAT), superoxide dismutase (SOD), glutathione S-transferase (GST), cytochrome P450 1A1 (CYP1A1) activities in G. pulex exposed to undecolorized (A1) and decolorized (A2) MG synthetic solution during 24 and 96 h were tested by using ELISA method. SOD and GPX enzyme activity was increased after decolorization (p > 0.05). CAT enzyme activity was increased in A2 group during 24 h (p > 0.05) but decreased during 96 h (p < 0.05). GSH levels were increased in A2 group during 24 and 96 h (p < 0.05). GST, CYP1A1 enzyme activity and MDA levels were decreased after decolorization during 96 h (p < 0.05). In this study, GSH levels, CAT, GST and CYP1A1 activities in G. pulex approved the capability of C. versicolor in MG decolorization, optimized with RSM
“Anaesthetic Efficacy of Aniba rosaeodora and Cinnamonum camphora Essential Oils for Goldfish (Carassius auratus)”
No full textMany researches have been conducted on goldfish, e.g. stripping eggs or sperm, morphometric
measurement, tagging, grading, hormonal injection, vaccination and transporting. All of these
applications cause stress that influence fish behaviour and physiology adversely, and anesthesia
is used generally for reducing the stress of fish. In this research, the optimal effective
concentration of two herbal essential oils, rosewood (Aniba rosaeodora) and camphora
(Cinnamomum camphora), were evaluated in the goldfish (Carassius auratus). Rosewood
species are scattered in the Amazon Region of Brazil, Guyana, Peru, Colombia, Venezuela, and
Suriname. The oil of Aniba rosaeodora is applied worldwide in the perfumery and cosmetic
industry due to its fragrance based on high linalool content (about 85%). Rosewood oil expected
to be an effective anaesthetic agent on fish owing to its high linalool component. Fish were
exposed to each anaesthetic concentration and the optimal effective concentrations were chosen
according to the criteria that induction stage should be achieved in less than 3 min and the
recovery time should not be exceeded 5 min. Based on this criteria, the lowest effective
concentrations of rosewood oil and camphora oil were detected. The induction time decreased
with increasing concentration for all of the anaesthetic agents evaluated. The recovery time
increased with the enhancing essential oils concentration. These results suggested that rosewood
oil is a new potential anesthetic agent for fish species in aquaculture
