The synthesis of high-temperature ceramic powders is examined through milling durations, reduction temperatures, and excess magnesium addition. Thermochemical analysis of probable reaction products was conducted by the Factsage software. According to the results, the thermochemical predictions and resultant powder phases showed good coherency. High-energy milling has a significant effect on the formation of the zirconium boride phase after annealing. However, extended milling time and higher annealing temperature have no significant effects on the composition of the constituted composite powders according to the X-ray diffraction results. An annealing temperature of 600 ºC was enough to obtain ZrB2-based ceramic composite powders. In the final powder phases, the excess magnesium addition to the stoichiometric displays an important feature. After the milling, annealing, and leaching procedure, the stoichiometric powder composition comprises ZrB2, ZrSi, ZrSi2, ZrO2, and MgSiO2, and excess Mg added powders have the ZrB2, ZrSi, ZrSi2, ZrO2 phases in their structure.

For this aim, different receipts were designed from boron waste (borogypsum) belonging to Emet Boric Acid factory (Kütahya/Turkey) and silica fume, which was taken from Electrometallurgy facilities (Antalya/Turkey). Mixtures were prepared so that the amount of waste material used in the composition was 90%, and the remaining 10% was binder clay. The samples were prepared with different proportions of both wastes were pressed uniaxially at 10 MPa, and the shaped samples were then fired at 1000, 1050, 1100, and 1150 °C. Physical and mechanical tests, as well as mineralogical and microstructural analyses, were carried out on the fired samples. The technical properties of the samples derived from the wastes were evaluated depending on the type of waste material and its usage amounts, and firing temperatures. It has been understood that the use of high Borogypsum will cause high firing loss, which will negatively affect the dimensional stability of the material. Moreover, with silica fume addition to borogypsum, the water absorption and porosity values increased, and the strength values decreased accordingly. Consequently, the water absorption and bending strength values obtained in the samples prepared from a mixture of 70% borogypsum and 20% silica fume can be considered the usage as a wall tile is possible since they coincide with the technical properties defined in the EN ISO 10545-3 and EN ISO 10545-4 standards, respectively.","PeriodicalId":431027,"journal":{"name":"Journal of Boron","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129329930","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, soil boron deficiency is a common nutrient problem for hazelnut growth. In this study, the effect of boron fertilizations of foliar and soil was investigated on the quality of hazelnuts (Corylus avellana L.) in two provinces in Turkey between 2013 and 2014. The experimental trials were carried out in soil application (0.0, 3.0 and 6.0 g per Ocak) and foliar spraying (0 and 300 mg B L-1). Results show that compared with the control, soil and foliar application of boron increased hazelnut yield and quality. Due to the two-year average, the highest yield of the hazelnut in Samsun-Çarşamba was obtained from the application and dose of S1. A 36.70% increase in hazelnut yield was achieved by applying B (3g Ocak-1) from the soil in comparison with the control application. It was a 20 % increase in Ordu-Ulubey district. The highest kernel ratio of hazelnut was obtained from F1S2 applications for the two districts. Increases were observed at Samsun-Çarşamba (10%) and Ordu-ulubey (7%). Results showed that there was also a positive association between the B leaf concentration and hazelnut yield and kernel ratio and no significant differences between foliar and soil applications on hazelnut quality. As a result of this study, and with increasing yield, foliar applications of B are an effective method of supplying sufficient B for the flowers. In addition, B leaf applications are more appropriate than soil B application.","PeriodicalId":431027,"journal":{"name":"Journal of Boron","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124490816","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Especially in species with low salinity and drought tolerance, salt stress may cause physiological and molecular changes such as plant growth and development, increase in secondary metabolite content in response to stress, and somaclonal variation. In this context, three different concentrations of boric acid, sodium perborate, sodium metaborate and disodium octaborate salts were applied to meristems isolated from in vitro clonal propagated L. orientalis and the effects of these boron salts on meristem regeneration and development were evaluated. When compared to the control group samples in which no salt application was applied, the best regeneration percentage was determined as 1mgL-1 disodium octaborate treatment with a value of 100%, while when the shoot forming capacity index was evaluated, 5mgL-1 sodium perborate treatment with a value of 4.94 gave the best results. However, when compared with the mother plant, it was observed that all salt treatments caused somaclonal variation on genetic stability, and in the light of the analyzed data, the lowest 30% (5mgL-1 disodium octaborate) and the highest 49% (1 mgL-1 boric acid) somaclonal variation were determined in all applications.","PeriodicalId":431027,"journal":{"name":"Journal of Boron","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128743477","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Karaciğer hastalıkları ve sonrasında gelişebilecek karaciğer yetersizliği insanlar için çok kritik bir klinik sorundur. Son yıllarda karaciğer hasarının kemoterapotiklerin, antiviral ilaçların ve bitkisel destekleyici ürün kullanımının artışı ile beraber insidansının arttığı görülmektedir. Bu nedenle günümüzde karaciğer hasarının tedavi edilebilmesi artık daha öncelikli olarak düşünülmektedir. Asetaminofen (APAP), dünyada en yaygın kullanılan, reçetesiz satılan analjezik ve antipiretik ilaçlarından biridir. Bununla beraber, aşırı dozda APAP alınmasına bağlı olarak karaciğer hasarı gelişebilir. APAP’ın N-asetil-benzokinonimin(NAPQI) metaboliti toksik etkinin ortaya çıkmasından sorumludur. NAPQI'nın hücre içi proteinlere, özellikle mitokondriyal proteinlere kovalent bağlanması, mitokondriyal oksidatif stresi ve nihayetinde hepatosit nekrozunu tetiklediği bilinmektedir. Bor içeren bileşiklerin antibakteriyel, antiviral, antioksidatif ve antiinflamatuvar özelliklerine sahip olduğu daha önceki çalışmalarda gösterilmiştir. Bor ve türevlerinin HIV, obezite, diabet ve kanser gibi hastalıkların tedavisinde faydaları bilinmektedir. Bu özellikleriyle antioksidan mekanizma üzerinden hepatosit nekrozu için umut vaat etmekte ve araştırılması gerekmektedir.
