A survey of few-shot learning in smart agriculture: developments, applications, and challenges
Get PDFWith the rise of artificial intelligence, deep learning is gradually applied to the field of agriculture and plant science. However, the excellent performance of deep learning needs to be established on massive numbers of samples. In the field of plant science and biology, it is not easy to obtain a large amount of labeled data. The emergence of few-shot learning solves this problem. It imitates the ability of humans' rapid learning and can learn a new task with only a small number of labeled samples, which greatly reduces the time cost and financial resources. At present, the advanced few-shot learning methods are mainly divided into four categories based on: data augmentation, metric learning, external memory, and parameter optimization, solving the over-fitting problem from different viewpoints. This review comprehensively expounds on few-shot learning in smart agriculture, introduces the definition of few-shot learning, four kinds of learning methods, the publicly available datasets for few-shot learning, various applications in smart agriculture, and the challenges in smart agriculture in future development
Antibacterial activity of aqueous and methanol extracts of Althaea officinalis and Althaea cannabina from Turkey
No full textThe chemical composition of essential oil and in vitro antibacterial activities of essential oil and methanol extract of Ziziphora persica Bunge
No full textThis study was designed to examine the chemical composition of essential oil and the in vitro antibacterial activities of essential oil and methanol extracts of Ziziphora persica. The inhibitory effects of essential oil and methanol extracts of Ziziphora persica were tested against 98 laboratory strains belonging to 51 bacteria species by using disc-diffusion assay and micro-broth dilution methods, respectively. GC and GC/MS analyses revealed that the essential oil predominantly contains (+)-pulegone (79.33%), limonene (6.78%) and piperitenone (4.2%). The antibacterial test results showed that both methanol extract and in particular essential oil of Ziziphora persica had antibacterial activity against a number of bacteria tested. The lowest MIC values (7.81 mu g/ml) were obtained with the essential oil of Ziziphora persica against Bacillus dipsauri, Corynebacterium cystitidis and Corynebacterium flavescens.

AN EXAMINATION ON THE USAGE NARRATORIN SEZAİ KARAKOÇ'SPIECES
No full textTürk edebiyatında büyük ölçüde şair kimliği ile tanınan Sezai Karakoç tiyatro türünde de eser vermiştir. Ertelenen Düğün, Çeyiz, Perde, Görev ve Armağan adlı beş kısa piyes yazan Karakoç'un bu yönü üzerinde çok durulmamıştır. Aynı zamanda, tiyatronun edebî bir eser olarak incelenmesinde “anlatıcı” unsuru da son yıllara kadar ihmal edilmiştir. Bu makalemizde Sezai Karakoç'un bu beş piyesini anlatıcı unsuru açısından ele alacağız. Yazarın anlatıcıdan ne şekilde yararlandığını irdeleyerek bu unsurun piyeslerindeki işlevini tespit etmeye çalışacağız. Makalemiz ile Türk tiyatrosu incelemelerine ve Sezai Karakoç hakkında yapılan çalışmalara katkıda bulunmayı amaçlamaktayız.Sezai Karakoç, who is widely known for his poet identity in Turkish literature has written pieces. Karakoç, who wrote five short plays as Ertelenen Düğün, Çeyiz, Perde,Görevand Armağan,has not been emphasized on this aspect of his. Therewithal, in the analysis of theater as a literary work, the “narrator” element has been neglected until recently. In this paper, we would deal with the five plays of Sezai Karakoç, whose plays have not been studied so much in terms of narrator. We will try to determine the function of this element in the pieces by examining how author uses the narrator in his pieces. With this paper, we aim to contribute to the studies of the Turkish theater and studies on Sezai Karakoç
MOTIVE OF ROSE IN SEZAI KARAKOÇ`S “FOURTY HOURS WITH HIZIR”
No full textSezai Karakoç is considered to be a person who created and affirmed the ideal of Turkish culture in which poetry takes prominent place. His poetry is distinguished with a rich artistic language and symbolism of images. Author, for example, attaches big importance to the image of a rose, which in general is one of the most used in the Turkish poetry. Sezai Karakoç lays some kind of bridge between the present, where he lives, and future with the help of his art. He puts a strong poetic and ideological tradition today, in which the cultural codes of his time become quite distinct and highly significant. Exactly because of the evolution of the image of rose in author`s poetry we can observe the process of his art evolution. One of the significant works, on which the researcher focuses special attention, is “Hızırla Kırk Saat”
Antibacterial Activities of Red Colored Radish Types (Raphanus sativus L.)
No full textThe root parts of red skin colored radish cultivars cv. Antep and cv. Cherry Belle which are belongs to Raphanus sativus L. were harvested from Erzurum region of Turkey and their methanol extracts were evaluated for antibacterial activity against 52 food borne bacteria by using disc diffusion assay. Extracts had a broad-spectrum antibacterial activity against food borne bacteria in broth micro dilution bioassays. Maximum antibacterial activity was observed against Arthrobacter ilicis, Corynebacterium ammoniagenes, Enterobacter hormaechei, Kocuria rosea, Neisseria subflava, Pantoea agglomerans, Proteus vulgaris, Psychrobacter immobilis and Shigella dysenteriae. However, cv. Antep showed antibacterial activity against Bacillus sphaericus and Corynebacterium flavescens and cv. Cherry Belle showed antibacterial activity against Arthrobacter atrocyaneus as well as. These inhibitory effects are interesting in relation to the prevention of microbial contamination in many foods
IN VITRO ANTIBACTERIAL ACTIVITIES OF BLACK AND WHITE RADISHES (RAPHANUS SATIVUS L.)
No full textThe present study was conducted to evaluate the in vitro antibacterial activities of methanol extracts of white and black coloured peel taproots of two radish types belonging to Raphanus sativus L. The antibacterial activities of the extracts were tested against 100 laboratory strains belonging to 52 bacteria species by using disc diffusion assay. The results showed that methanol extract in taproots of both black and white radishes had antibacterial activity against Arthrobacter atrocyaneus, Corynebacterium ammoniagenes, Enterobacter hormaechei, Kocuria rosea, Neisseria subflava, Pantoea agglomerans, Proteus vulgaris, Psychrobacter immobilis and Shigella dysenteriae. White radish type showed antibacterial activity against Bacillus sphaericus and Corynebacterium flavescens as well. Based on results, it is possible to conclude that white radish has a stronger and broader spectrum of antibacterial activity as compared to black radish
A short review of the fruit germplasm resources of Turkey
No full textTurkey is one of the most significant and unique countries in the world from the point of view of plant genetic resources and plant diversity. Over 85 fruit species, including almost all the deciduous fruit species, most of the subtropical and some tropical fruit are grown. Matters regarding their distribution within the provinces, nomenclature, characteristics, ethnobotanical aspects and uses are discussed, as well as knowledge about the germplasm of those species of greater economic importance, namely Malus spp., Pyrus spp., Cydonia spp., Crataegus spp., Sorbus spp., Amygdalus spp., Prunus spp., Castanea sativa L., Coryllus spp., Pistacia spp., Juglans regia L., Ribes spp., Ficus spp., Morus spp., Punica granatum L., Rubus spp., Rosa spp., Fragaria spp., Cornus mas L. and Olea spp. Several tables and distribution maps of some fruit species in Turkey are included
