Plant image retrieval using color, shape and texture features

We present a content-based image retrieval system for plant image retrieval, intended especially for the house plant identification problem. A plant image consists of a collection of overlapping leaves and possibly flowers, which makes the problem challenging.We studied the suitability of various well-known color, shape and texture features for this problem, as well as introducing some new texture matching techniques and shape features. Feature extraction is applied after segmenting the plant region from the background using the max-flow min-cut technique. Results on a database of 380 plant images belonging to 78 different types of plants show promise of the proposed new techniques and the overall system: in 55% of the queries, the correct plant image is retrieved among the top-15 results. Furthermore, the accuracy goes up to 73% when a 132-image subset of well-segmented plant images are considered

Prunella vulgaris l. ve prunella grandiflora l.’den saflaştırılan rosmarinik asitin farklı tümör hücreleri üzerindeki sitotoksik aktivitesi

Rosmarinic acid was isolated from ethanol extractions obtained from Prunella grandiflora L. and P. vulgaris L. The total phenolic content of ethanol fractions during isolation was determined by the Folin-Ciocateu method. The cytotoxic doses of the isolated rosmarinic acid were determined by WST-1 (Roche Applied Sciences, Mannheim, Germany) cell proliferation assay. A 10-60ng cytotoxic dose was determined for pancreas (PANC-1), prostate (PC-3), colon (HT-29) and breast (MDAMB 436) cancers and GBM (T98G) cell lines and lymphatic tissues. 24 and 48h incubation periods were applied during dose determinations. An antiproliferative effect was observed at the end of 48h incubation period with 50ng rosmaniric acid treatment in PC3 cell line and with 60ng treatment in PANC-1, HT-29, MDA-MB 436 and T98G cell lines. No cytotoxic activity of rosmarinic acid was observed in non-tumor cells.Bu çalışmada rosmarinik asit bileşiği, Prunella grandiflora L. ve P. vulgaris L. türlerinden elde edilen etanol ekstraktlarından saflaştırılmıştır. Saflaştırma işlemi sırasında elde edilen metanol fraksiyonlarının toplam fenol içeriği FolinCiocalteu yöntemi ile belirlenmiştir. Prunella L. türlerinden saflaştırılan rosmarinik asitin farklı kanser hücreleri üzerinde WST-1 (Roche Applied Sciences, Mannheim, Almanya) yöntemiyle sitotoksik doz çalışmaları yapılmıştır. Buna göre pankreas (PANC-1), prostat (PC-3), kolon (HT-29) ve meme (MDA-MB 436) kanserleri ile GBM (T98G) hücre hatları ve lenf dokularında 10-60ng arasında sitotoksik doz belirlenmiştir. Sitotoksik doz belirleme çalışmaları için 24 ve 48 saat inkübasyon süreleri çalışılmıştır. 48 saat inkübasyon süresi sonunda PC3 hücre hattı için 50ng ve PANC-1, HT-29, MDA-MB 436 ve T98G hücre hatları için 60ng rosmarinik asit uygulamasında antiproliferatif etki gözlenmiştir. Sağlıklı hücrelerde rosmarinik asitin sitotoksik etkisi gözlenmemiştir

Organik Sultani Çekirdeksiz Üzüm Yetiştiriciliği

Bu projede, organik ürün olarak, talebi oldukça fazla Sultani Çekirdeksiz kuru üzüm üretimi ele alınmıştır. Çalışma, iki alt projeden oluşturulmuştur. I. Alt projede organik tarımda istenen minimum toprak işlemesi yanında ülkemizde bulunan ve birçok olumlu özelliklere sahip Zeolit (Klinoptilolitie mineral [Agro-clıno (NMF 900)]) kullanımı da denemede yer almıştır. II. Alt proje de ise Ege Bölgesi bağlarının ana hastalığı olan külleme mücadelesinde NaHCO3’ (içme sodasının) mevcut koşullardaki kullanım olanakları projede ele alınmıştır Bağlardaki ana zararlı da salkım güvesi olup her iki alt projede, salkım güvesi mücadelesinde tuzaklar asılarak zararlının ergin populasyonu bu tuzaklarla ilk ergin çıkışından uçuşlar sona erinceye kadar haftalık olarak izlenmiştir. Uçuş eğrileri ile tahmin-uyarı istasyonlarından elde edilen meteorolojik veriler ışığında gerekli uygulamalar yapılmıştır. Çalışmanın sonucunda, KULTIVATOR ile toprak işleme sisteminin toprağa olumsuz etkisinin de en az düzeyde olduğu da dikkate alınarak önerilebileceği ortaya çıkmıştır. Yeşilyurt yöresi topraklarındaki mikrobiyal aktiviteyi arttırmada malç uygulaması önerilmesine karşın, bu uygulama diğer disiplinler tarafından uygun görülmediğinden alternatif olarak KULTIVATOR uygulaması tercih edilmektedir. Kükürt ve içme sodası uygulanan parsellerde külleme hastalık şiddeti konvansiyonel olan şahit parsele göre istatistiki öneme sahip düzeyde azalma kaydetmiştir. Konvansiyonel koşullardaki hastalığın daha fazla görülmesini uygun koşulları yaratacak yoğun vejetatif gelişmenin yaratmış olduğu düşünülmektedir. Kükürdün zararlıları baskılayıcı etkisi de bilindiğinden organik yetiştiricilikte Külleme mücadelesinde içme sodasına nazaran özellikle kükürdün tercih edilmesi uygun bulunmaktadır. Denemenin başladığı 2003 yılı baz alındığında Zeolit (Klinoptilolitie mineral [Agro-clıno (NMF 900)]) uygulamalarında verim ve kalite kriterlerinde artış olduğu tespit edilmiştir. Toprak işleme uygulamalarından toprağı çizerek işleme salkım sayısı ve verim bakımından önemli bulunurken pulluk+ diskharow ile işleme salkım ağırlığını; malç uygulamasının ise kuru maddeyi ve tane tutumunu arttırdığı görülmektedir. Yaprak alma uygulamalarından, 6 adet yaprak alınması kontrole nazaran verim, salkım sayısı ve salkım ağırlığını nispeten arttırmıştır. Proje konusu çalışma birimleri itibarıyla değerlendirildiğinde toprağın çizilerek işlenmesi (KULTIVATOR sistemi) ön plana çıkmaktadır

Image retrieval for identifying house plants

We present a content-based image retrieval system for plant identification which is intended for providing users with a simple method to locate information about their house plants. A plant image consists of a collection of overlapping leaves and possibly flowers, which makes the problem challenging. We studied the suitability of various well-known color, texture and shape features for this problem, as well as introducing some new ones. The features are extracted from the general plant region that is segmented from the background using the max-flow min-cut technique. Results on a database of 132 different plant images show promise (in about 72% of the queries, the correct plant image is retrieved among the top-15 results)

Universities' Perceptions and Applications of Business Ethics: Research on the Black Sea Universities Network

Unal, Aslihan/0000-0001-5896-8880WOS: 000475905800003The main purpose of this research is to examine the business-ethics perceptions of universities belonging to the Black Sea Universities Network by considering them as organizations and to define the activities, principles, and codes they adopt or don't adopt in the field. The population of the research consists of nine universities registered in the network. Data from online interviews with seven of the universities' secretary-generals and assistant secretary-generals and documents provided from these universities' official web sites have been used as the dataset. The semi-structured interview method has been followed in collecting the interview data. The interview form consists of 10 open-ended questions and is supported by probing questions; the form has not been strictly adhered to during the interviews. The interview data have been analyzed using qualitative content analysis following a deductive approach. The predetermined categories of ethical perceptions, activities and practices of universities on business ethics, and the principles and codes of business ethics were searched in the data. As a result of content analysis, universities have been identified as having inadequate ethical perceptions, four universities to have organized ethical committees, and three universities to have issued directives on business ethics

The Adaptation of a Scale for Preschool Teachers' Attitudes Towards Science Teaching

This study was designed to adapt into Turkish the "Early Childhood Teachers' Attitudes towards Science Teaching Scale" developed by Hyung-Sook-Cho et al. (2003). The research data were collected from teachers, working with children at the age group of six in public or private nursery schools or nursery classes affiliated with the Ministry of National Education, in Ankara and Malatya, Turkey. For validity testing, factor analysis and item analysis were conducted; and for reliability testing, internal consistency and test-retest reliability methods were used. The findings of these tests demonstrate that the validity and reliability of the scale are at a sufficient level. (C) 2010 Elsevier Ltd. All rights reserved.WoSScopu

Effect of different kefir source on fermentation, aerobic stability and microbial community of alfalfa silage

The present study has been one of the first attempts to thoroughly examine the effects of different kefir sources on fermentation characteristics, aerobic stability, and microbial communities of alfalfa silages. The effects of commercial kefir (CK) and homemade kefir culture (HK) applied with untreated a common control (CON) and three different application doses (5.0, 5.7, and 6.0 log cfu g?1) on wilted alfalfa and stored at an ambient temperature of 25–30 °C are studied. After 45 days of ensiling, fermentation characteristics and aerobic stability of silages were measured, and bacterial diversity was investigated by 16S ribosomal RNA gene sequencing using the GenomeLab™ GeXP platform. Both CK and HK accelerate more lactic acid production and reduced ammonia nitrogen concentration. Factor analysis of kefir sources suggests that the addition of kefir improves the aerobic stability of silages, even the initial water-soluble carbohydrate (WSC) content is inadequate via its antimicrobial effect on yeast and mold formation. Enterococcus faecium, Pediococcus pentosaceous, and Lactobacillus brevis were dominant bacterial species among the treated groups at silo opening, while Lactobacillus plantarum and Lactobacillus brevis became dominant bacterial species after 7 days of aerobic exposure. In conclusion, the application of kefir on alfalfa silages improves fermentation quality and aerobic stability even with low WSC content. © 2021 by the authors. Licensee MDPI, Basel, Switzerland
