In this paper, we introduce the new class of implicit L-stable generalized hybrid methods for the numerical solution of first order initial value problems. We generalize the hybrid methods with utilize ynv directly in the right hand side of classical hybrid methods. The numerical experimentation showed that our method is considerably more efficient compared to well known methods used for the n...

Rose is the most favorite cut flowers all over the world. Production of high-quality flowers, prevention, and delay of flower senescence, is a major goal in floriculture. Now a day, biotechnological approaches have been used to improve ornamental attributes. Tissue culture and genetic transformation appear to offer valuable advancements for operating floral characteristics. In this study, after...

In recent years, the use of natural anthocyanin as a biocolour in business has grown to peak and there is an increasing desire enhance extraction procedures. this study, various techniques (Conventional extraction, Microwave assisted Ultrasound extraction) for extracting from Hibiscus rosa-sinensis petals using water, ethanol, citric acid solvents have been investigated. Total Anthocyanin, Anti...

Bu çalışmada, 2019–2021 yılları arasında Bayburt ilinde tespit edilen 11 familyanın 20 cinsine ait 54 odunsu, etli, yabani meyve bulunduran takson verilmiştir. taksonun 4’ü (%7,4) endemiktir. Tespit taksonların fitocoğrafik bölgelere göre dağılımları şöyledir; %67’si çok bölgeli ya da bölgesi bilinmeyenler, %15’i Akdeniz, %9’u İran-Turan, %7’si Karadeniz ve % 1’i ise Hirkanya-Karadeniz bölge el...

Three new inorganic-organic hybrid materials based on heteropolyoxometalates, [L-C6H14NO2]3[(PO4)Mo12O36].3H2O (1), [L-C5H10NO2]3[(PO4)W12O36].H2O (2), and [C2H7N2O]3[(PO4)W12O36]. 4H2O (3), where C6H14NO2, C5H10NO2, and C2H7N2O are protonated L-leucine, L-proline, and methylurea, respectively, have been synthesized and structurally characterized by some physico-chemical methods. Elemental anal...

Antimicrobial activity and cytotoxicity of fifty one extracts of different parts of 14 plants were studied. Ethanol, methanol, aqueous, butanol, and n-hexane extracts were tested against three gram negative, two gram positive bacteria, and two fungi. Cytotoxicity and phytochemical screening were determined using MTT and TLC assays, respectively. Of the fifty one extracts, twenty two showed acti...

This paper explores the use of Topic Maps to represent Learning Objects (LOs) in ROSA (Repository of Objects with Semantic Access for eLearning). ROSA is an e-learning system, which enables the creation, storage, reuse and management of LOs. A LO, characterized by a set of metadata descriptors, is a collection of reusable material used to support learning, i.e., an entity that can be digital or...

The cardiac ischemia-reperfusion (I/R) injury greatly influences the therapeutic effect and remains an urgent challenge in clinical therapy. Polypharmacology opens a new therapeutic opportunity to design drugs with a specific target for improving the efficacy. In this study, we first forecasted that Rosmarinic acid (RosA) could be used for the treatment of cardiovascular disease using text mini...
