Çeliklerin Korozyonuna Boraksın Etkisi

Abstract

Bu çalışmada Ç 1010, Ç 304 ve Ç 316 çeliklerin korozyonuna boraksın (Na 2 B 4 O 7 ) etkisi araştırılmıştır. Bu amaçla farklı derişimlerde (0,0125 M, 0,025 M, 0,050 M ve 0,100 M) borakslı çözeltiler hazırlanmıştır. Çeliklerin bu ortamdaki elektrokimyasal davranışını belirlemek için Dönüşümlü Voltametri (CV) tekniği, korozyon hızlarını ölçmek için ise Tafel Polarizasyon Yöntemi uygulanmıştır. Deneyler sonucunda boraks derişiminin artması ile her üç çelikte korozyon hızının azaldığı ve korozyon potansiyelinin arttığı tespit edilmiştir. En yüksek boraks derişiminde en düşük korozyon hızı Ç 316 çeliğinde belirlenmiştir. Ç 1010, Ç 304 ve Ç 316 çeliklerin 0,100 M boraks derişiminde korozyon hızları sırasıyla; 0,251, 0,132 ve 0,071 mm/yıl olarak ölçülmüştür. Boraks anodik inhibitör davranışı göstererek çelikleri korozyondan korumuştur. Çeliklerin borakslı çözeltilerde güvenle kullanılabileceği sonucuna varılmıştır.

Case Review: Whole-Exome Sequencing Analyses Identify Carriers of a Known Likely Pathogenic Intronic BRCA1 Variant in Ovarian Cancer Cases Clinically Negative for Pathogenic BRCA1 and BRCA2 Variants

“…These cases were subjected to WES and a customized bioinformatics pipeline for germline variant calling at the McGill Genome Center, as previously described [27]. NimbleGen SeqCap ® EZ Exome Kit v3.0 (Roche, USA) was used to capture 64 mega base pairs of coding, non-coding and flanking intronic regions of up to 100 base pairs, where the average coverage of the coding region was 100×, and that of the flanking intronic region was 60× [28,29]. Then, the annotated variant call format (VCF) files were subjected to additional filtering and prioritizing criteria as follows.…”

Genetic Diversification of Starch Branching Enzymes during Maize Domestication and Improvement

“…The genomic DNA of each line was extracted from three mixed leaves (approximately 15 days after the emergence of maize) using the CTAB (cetyl trimethyl ammonium bromide) method [14,15]. The sequences (B73_V3 reference genome) of the ZmSBEI (GR-MZM2G088753), ZmSBEIIa (GRMZM2G073054), ZmSBEIIb (GRMZM2G032628), and ZmS-BEIII (GRMZM2G005298) gene in all tested lines were sequenced using the target sequence capture sequencing technology on the NimbleGen platform [16,17] by BGI Life Tech Co., Ltd (Guangdong, China). The reference sequences captured by the target sequence were the ZmSBEs gene sequences in the background of the B73 inbred line (Table S2).…”

Come as You Are: Examining Autistic Identity Development and the Neurodiversity Movement through an Intersectional Lens

“…While there have been pockets of intersectional thinking in both the autism and autistic community 1 (Baggs, 2016;Barnett, 2017;de Hooge, 2019;Giwa Onaiwu, 2020;Hannon, 2017;Mallipeddi & Van-Daalen, 2021;Mandell et al, 2007;Moore et al, 2022;O'Dell et al, 2016) with particular attention given to issues of representation of autistic people with co-occurring disabilities (e.g., Baggs, 2010;Chapman & Veit, 2020), the majority of the work in both communities has suffered from a lack of engagement with intersectional issues. Collectively, we are only beginning to grapple with the degree to which intersectionality has been neglected in autism practice, research, and activism (e.g., ASAN, 2021;Cascio et al, 2021;Jones et al, 2020). To date, the narratives and rhetoric surrounding autism and autistic people have been intertwined with a pervasive and persisting whiteness, cis-gender, middle-class, straight, maleness (de Hooge, 2019;Giwa Onaiwu, 2020;Wright, 2021).…”

“…For example, Sojourner Truth's "Ain't I A Woman" speech in 1851 called for recognition and respect for the experiences of Black women. Intersectionality also served as a foundation for subsequent advocacy, including ongoing work to ameliorate the pronounced under-representation of Black autistic people and other autistic people of color in leadership roles (ASAN, 2021;Brah & Phoenix, 2004;Strand, 2017). Similarly, the term neurodiversity grew from a history of advocacy, such as the birth of the first autistic-led advocacy organization in 1992, Autism Network International (ANI; Sinclair, 2010), and sparked subsequent collective action, including the formation of the Autistic Self Advocacy Network (ASAN) in 2006.…”
