Potassium borates, which are widely used in welding and metal refining industry, as a lubricating oil additive, cement additive, fiberglass additive and insulation compound, are one of the important groups of borate minerals. In this study the production of a potassium borate mineral via hydrothermal method is aimed. The potassium source of potassium nitrate (KNO3) was used along with a sodium ...
Yem bezelyesi (Pisum sativum spp. arvense L.), yüksek ot verimi ve içeriğinde %20 civarında ham proteine sahip bir yem bitkisidir. tüm yetişme dönemlerinde mikro elementlere ihtiyaç duyduğu herkes tarafından bilinse de bu elementlerin bitki yetiştirmenin en hassas dönemi yani çimlenme fide gelişim dönemindeki rolü pek fazla araştırılmamıştır. Bu çalışmada, bor çinko elementlerinin bezeleyesi to...
The current study investigated the effect of boric acid (H3BO3) nanosized powder on optical properties a Computer-Aided Design and Manufacturing (CAD-CAM) polymer infiltrated ceramic material. Specimens (n = 60), (15 × 8 1.5 mm3) were fabricated from network (PINC) (Vita Enamic, Vita Zahnfabrik, VITA-shade scale A2). Boric (B) nano was applied to Enamic in half specimens 30), while other left u...
Background: In rainfed agriculture, lentil is considered an important legume crop. But in conditions adequate soil moisture condition a major obstacle that leads to reduced germination per cent, slow down growth of the seedlings and finally reduction yield. Seed priming alternative which can improve percentage seedling establishment lentil. Methods: The present work, deals with (Lens culinaris ...
Synthesis of 2,3-dihydroquinazolin-4(1H)-ones using H3BO3/montmorillonite K10 (H3BO3/mont K10) catalyst has been reported. H3BO3/mont K10 and H3BO3/mont K30 have been prepared and used as catalysts in the reaction between anthranilamide and benzaldehyde to prepare 2-phenyl...
Chemical oxo-preceipitation (COP) process that combined the oxidant treatment and precipitation using metal salts was developed for boron containing water disposal under relatively milder conditions (room temperature, pH 10) than a precipitation process. Among the selected boron compounds in 1000 mg-B L, including boric acid (H3BO3), metaborate (NaBO2), borax (Na2B4O7) and perborate (NaBO3), th...
Little information is available on the molecular mechanisms of boron (B)-induced alleviation of aluminum (Al)-toxicity. 'Sour pummelo' (Citrus grandis) seedlings were irrigated for 18 weeks with nutrient solution containing different concentrations of B (2.5 or 20μM H3BO3) and Al (0 or 1.2mM AlCl3·6H2O). B alleviated Al-induced inhibition in plant growth accompanied by lower leaf Al. We used cD...
Turkey has 72 % of total world boron reserves on the basis of B2O3.Borates that is a refined form of boron minerals have a wide range of applications. Zinc borates can be used as multifunctional synergistic additives. The most important properties are low solubility in water and high dehydration temperature. Zinc borates dehydrate above 290°C and anhydrous zinc borate has thermal resistance abo...
Determination of Self-Compatibility of the 'Arsel' Olive Cultivar Obtained by Hybridization Breeding
This study was aimed to determine the fertilization biology of 'Arsel' olive cultivar obtained by hybridization breeding. For this reason, treatments open pollination, cross and self-pollination were performed for 2 years self-compatibility appropriate pollinators new investigated. Among varieties included as (‘Memecik’, ‘Gemlik’, ‘Uslu’, ‘Ayvalık’ ‘Eğriburun Nizip’), highest fruit set achieved...
نیاز به تحقیقات پایة گیاهی تحت شرایط پیچیدة فضا بارها توسط سازمانهای فضایی دنیا، از جمله ناسا، عنوان شده است. هدف از پژوهش حاضر بررسی اثرات میکروگراویتی القایی روی رویش و رشد لوله گرده لیلیوم میباشد. در این تحقیق، میزان زیستپذیری دانههای گرده توسط روش رنگآمیزی با استوکارمن تعیین شد. دانههای گرده لیلیوم در محیط کشت مایع حاوی 10 درصد سوکروز، 6/1 میلی مول H3BO3، 1 میلیمول KCl و 1/0 میلیمول...
